AJAX and the Refresh Button

Adam Winer - Tue, 2007-07-31 17:12
JSF relies heavily on <input type="hidden" name="javax.faces.ViewState"> for its lifecycle. This hidden field carries all UI state for the page. Whether that's client-side state (with the entire page Base64-encoded) or server-side state (with a simple token), it's important that the right field be delivered with any JSF postback for the page to function correctly.

As a result, AJAX implementations in JSF typically need not only to submit this value to the server when posting an AJAX request, but also to update it as necessary when a request completes. While looking at an ADF Rich Client bug recently, I was rudely reminded that the Refresh/Reload button doesn't always behave as you might imagine, and thought it was worth delving into the details. (I'll be talking about JSF, but the behavior is generic to DHTML and applies outside of JSF, and the code samples are just raw HTML.)

Take the following page:



<html>
<head>
</head>
<body>
<form name="foo">
<div id="valCtr">
<input name="val" type="hidden" svalue="1">
<script>
document.forms.foo.val.value=1;
</script>
</div>

<a href="#" onclick="forms.foo.val.value =
parseInt(forms.foo.val.value) + 1; return false;">
Increment</a>
</form>
</body>
</html>


Now, in your favorite browser, try the following:
  • Click Display (you'll see 1)
  • Click Increment a couple of times
  • Click Display again (you'll see 3)
  • Click or select Refresh/Reload (but not Shift-Refresh)
  • And Display once more. You'll still see 3 (unless you're using Safari)
  • Now, Shift-Refresh, and Display. Now we're back at 1.
What have we seen? Refresh has re-queried the HTML for the page, but instead of resetting the value of our hidden input field back to 1, it's stored the updated value of 3! This isn't a bug - so says this Bugzilla bug (and all 61 duplicates!) Microsoft would agree with Mozilla here. Of the big 3, only Safari doesn't overwrite form fields on reload. (The caching behavior is in fact very handy for Back/Forward, and is exploited by the Really Simple History framework.) Shift-refresh fully reloads the page, and drops the form element cache.

This can lead to big problems in a JSF application. Take the following scenario:
  • A page initially renders with state token 1 in a hidden field
  • An AJAX request updates the state token to 2
  • The user hits Reload, and the new HTML contains state token 3
  • But the browser ignores it, and overwrites it with state token 2!
Now we've got a page in state "3", but a token claiming it's really in state "2". This is bad. As always, let's see what alternatives we've got, and whether they suffer from the same problem.

First, how about creating the DOM on the fly?


<script type="text/javascript">
function incrementViaDOM()
{
var value = parseInt(document.forms.foo.val.value) + 1;
var newField = document.createElement("input");
newField.name = "val";
newField.type = "hidden";
newField.value = "" + value;
var oldField = document.forms.foo.val;
var parent = oldField.parentNode;
parent.replaceChild(newField, oldField);
}

</script>

<a href="#" onclick="incrementViaDOM(); return false;">
Increment with replaceChild</a>


In Firefox, this still doesn't help. The hidden field value is still cached. (And this example doesn't work at all in IE... see this entry for why and how to fix it.)

OK, how about innerHTML?


<script type="text/javascript">
</script>

var value = parseInt(document.forms.foo.val.value) + 1;
var valCtr = document.getElementById("valCtr");
valCtr.innerHTML = "<input name=\"val\" " +
"type=\"hidden\" value=\"" + value + "\">";

<a href="#" onclick="increment(); return false;">
Increment with innerHTML</a>


Now this works... changes made by innerHTML are not remembered by Firefox or Internet Explorer (or Safari). So, if you don't want a hidden field cached, update with innerHTML and browsers won't hassle you.

Alternatively, you could look at tackling this issue during the refresh, by forcibly resetting the value from Javascript:


<input name="val" type="hidden">
<script type="text/javascript">
document.forms.foo.val.value=1;
</script>


This works in Firefox, but does not in IE. Whatever code overwrites the value of the hidden field runs after this inline script, but before the page's onload handler. So, if you want to tackle this problem while refreshing, you'll have to do it in onload.

To (finally) come back to JSF, there's a better way to solve this problem, at least for the state token. Use a StateManager that automatically doesn't generate new tokens for AJAX requests, but instead reuses the old token. New tokens are important when you're rendering a new page, but are a waste of space when you're just working on a single page. And, as a nice side-effect, this makes this issue moot. (MyFaces Trinidad 1.0.2 will include this token-reuse optimization, though it's always used innerHTML for updating the state token, so it hasn't been hit by this bug.)

So, to summarize, if you have a programatically-modified, hidden input field that needs to be Reload-proof, two techniques look good:
  • Use innerHTML to update the field
  • Use onload to set the hidden input field value


If you've got any other tricks, I'd be happy to know.

Know Thyself

Mary Ann Davidson - Tue, 2007-07-31 07:47

I am trying something a bit different with this blog entry, which is to tag team it with a colleague. The idea for this entry came out of an email exchange inside Oracle about identity and privacy. It was an interesting enough discussion that a third colleague thought it would be worthy of a blog entry. From my perspective, it's a chance to work with a great colleague and vent my spleen while doing so. What's better than that?


I should do a brief introduction here to my co-blogger, Roger Sullivan, who is VP of Business Development for Oracle Identity Management. I could provide Roger's more formal CV but suffice it to say that on a "street creds" level, Roger is a very well respected identity management kahuna (e.g., he is also President of the Liberty Alliance).  On a more personal level, a few years ago, Oracle acquired a company of which Roger was then-CEO. I remember punching the air with multiple "woo hoos" when I heard the news, because I knew Roger and thought that the fact we were "acquiring" him as part of the deal was at least as important as the technology (which itself was pretty cool).
 
The original email exchange Roger and I (and others) had was around federated identity. There is probably a fancier definition of federated identity with which Roger can enlighten us, but as a practical matter you can think of it as being able to have an "identity" that is recognized in multiple arenas that have some business relationship among them. For example, suppose I go to a web site for FooHotels. FooHotels has a business relationship with a car rental agency, RentHotCars (they offer joint car rental/hotel packages, and you get hotel points for renting cars and vice versa). From a consumer standpoint, I'd like to be able to go to a single web site, book a hotel and rent a car (and get all those points!) without having to separately identify myself to each entity. In particular, if I jump to RentHotCars.com from FooHotels.com, I'd like to be able to do that without typing in yet another cryptic username and password. I can do that through the magic of federated identity.
 
One of the beauties of federated identity is that the standards work in this area was driven by real businesses (not merely technologists in search of a problem to solve "elegantly"). As such, a lot of work to-date has been pragmatic, implementable, and focused on a clear problem that it would be useful to solve. And Roger has been a leader in developing those standards. Woo hoo!
 
&lt;Roger> Mary Ann, you are too kind.  I think it is safe to say that all of the Identity Management acquisitions, including the recent announcement of Bharosa joining the family have, been great moves for Oracle and our customers.  The synergies created by the union of these "best of breed" companies have been truly remarkable and have catapulted Oracle into a leadership position in the Identity Management market.
 
Mary Ann has provided a great description of the essentials of Federation.  What else would I say to a former U.S. Navy officer with a loaded weapon?  (Read on...)
 
Federated Identity Management provides benefits to each of the participants.  For the Service Provider, federation extends their reach into their markets.  For the Identity Provider, it provides a singularly secure mechanism of storing the essential identity elements.  And for the individual user, it provides a safe and secure means of disclosing only the required information necessary for the task at hand.
 
&lt;Mary Ann> To me, the business need (and utility as a user) of a being able have a federated identity is a different issue than having (or needing to have) a single identity recognized by lots of disparate entities who don't have a business relationship. This lack of business need (dare I say Need to Know?) coupled with many people's natural desire for privacy to me means that we don't actually need a single identity and in fact, I'd really resist it. I do resist it.
 
For example, I have multiple "identity cards" in my wallet (I have lots of them in fact, judging by the thickness of my wallet). These identities are issued by different organizations, each of which has a different authority to issue them (and don't in general need to know of my other personas). For example, I have a concealed weapons permit in the state of Idaho (which required me, among other things, to take a gun safety class and pass an FBI check). I also have an American Express card. American Express neither knows nor cares that I am licensed to carry concealed in Idaho and the state of Idaho presumably neither knows nor cares what my credit rating is, as long as I pay my taxes on time. This is one reason why I have two cards: it reflects the fact that these identities have no relationship with each other, and each has "authority" to recognize "Mary Ann's identity" that are unrelated. They don't even need to know I am the same person.
 
&lt;Roger> Mary Ann has hit upon the fundamental issue that concerns many who are using web-based services.
 
Consider the following example of how we interact in our daily (non-electronic) lives.  Let's say that I'm driving home from work and receive a call from my wife asking me to stop at the store for some milk.  I don't have much cash, so I swing by my bank's ATM machine.  This simple example involves at least four distinct identity elements.  [Pause now while the "Jeopardy" music plays and you try to identify at least four forms of identity.]
 
The cell call will probably have my wife's name on the screen as I answer because her number is passed through the cell network and I have that number associated with her name in my contact list.  There is reasonably strong assurance that it will be her on the other end, unless she has loaned the phone to someone else.
 
At the ATM machine, I'll need to insert my ATM card (something I have) and enter a PIN code (something I know) in order to provide multi-factor authentication that it's really me trying to access my bank account.  This is good for the bank and especially good for the security of my funds.  I like providing these extra steps.
 
At the convenience store, the only "authentication" required is that of the $5.00 bill that I present for the milk.  For some transactions, there is an implicit right to anonymity.  Neither the store clerk nor I have any need to know the other's identity for this transaction.  If, on the other hand, I looked considerably younger than I do and was buying beer, the clerk would have an obligation for me to provide proof of legal age on some sort of recognized identity card.  I know that this is expected in the various day-to-day transactions in which I participate.
 
What we want to achieve in the electronic world, is the same kind of humanly intuitive interaction with web-based services.  The minimal set of appropriate credentials - and only those - provided for the transaction at hand.
 
[PS: The 4th form was my driver's license with beaucoup identity information on it.  If I want the privilege of driving, then I will agree to carry and provide this authentication mechanism to the local constable on reasonable demand.]
 
&lt;Mary Ann> Unfortunately, more and more of our representative identities are linked through the magic (or curse) of Social Security Numbers (SSNs). As such, we have the "collapsing" of identity, sort of the metaphysical equivalent of having one persona instead of many, which has made it a lot easier for identity thieves to flourish. It used to be the case that losing a single credit card did not lead to an identity theft nightmare. You just called the company and cancelled the card (I only did this once, when I "lost" a credit card that later turned up).  Now, if you lose (or misplace) one "identity" that is based on your SSN, or someone else gets access to it, they can often "link" to all your other personas. You didn't lose one card, you lost your entire identity.
 
The entire identity theft explosion has been fueled by too darn many people using Social Security Number for purposes for which it was never intended: as a single unique identifier (that enables linkages between non-related personas, many times for no purpose that could possibly be construed as beneficial to a user).  Putting it differently, if my magazine subscription record is leaked, so people know that I take Surfer's Journal, I really would not care. (So what? It's a great publication and no harm to me if people know I read it.)  However, if my "subscription record" were to include my Social Security Number (for no good reason, and there is no good reason to use it), I am in deep kimchee because that SSN allows a bad guy access to many other Mary Ann personas. Bad guy can "become" me.
 
If a Social Security Number is ubiquitous (and it is) but not secret (it has been used as people's health care number and driver's license number, conveniently located on your health care card or driver's license in 12 point font, bold) and the key to "who you are," it is the perfect storm of one "key" (which is not secret and cannot be changed) unlocking your entire identity, so that it can be stolen. The only worse thing would be substituting your fingerprint as your "unique identifier," which is also not secret and can't be changed.
 
I confess to being a professional crank on this issue. Some years ago, I registered for a class at UC Berkeley Extension (which had and presumably still has excellent classes). They wanted my Social Security Number in order for me to register. Here's how the dialogue went:
 
UCB: "We'd like your Social Security Number."
Me: "Why, is this a taxable event? Because if it isn't, you shouldn't be using SSN."
UCB: "We want to uniquely identify you."
Me: "That's your problem. I know perfectly well who I am. Besides, if you want a unique identifier, use a database sequence number. Trust me; I know about these things."
 
I won the argument through sheer stubbornness. (In the interests of full disclosure, I am told that UC Berkeley no longer uses SSN as student identifiers, so good on them. Perhaps in my own small, cranky way, I helped them see the light.)
 
I should note that Oracle has technology (transparent data encryption, woo hoo!) that can encrypt columns (or entire tablespaces, as of Oracle Database 11g) of sensitive information like Social Security Numbers. It's a nice weapon in the security person's arsenal. A great one, in fact. But the entire world is not Oracle, and encryption, as wonderful as it is, doesn't help you if the data is "inappropriately accessed" in decrypted form.  Eventually, data - any data - has to be decrypted to use it.
 
&lt;Roger> As Mary Ann points out, Oracle provides sophisticated security mechanisms in order to protect the information that our solutions manage.  In addition, we strongly believe that these solutions must be based on industry proven standards.  This provides our customers with the investment protection and flexibility that web-based applications require in a connected world.  There is a very long list of boring acronyms that detail the identity-related standards that our products support.  Moreover, there are equally long lists of standards for virtually every product area in the company.  A fundamental criterion for the successful integration of acquired companies is their adherence to relevant standards.  This enables Oracle to quickly achieve a return on its acquisition investment.


&lt;Mary Ann> Clearly, there are times when an organization needs to collect sensitive information (like your employer, who needs your SSN to for tax reporting purposes). Many organizations take appropriate care to secure that information. Those aren't the folks that make my blood boil.
 
You do have to ask, and I have, why is really sensitive data being collected by so many people who do not need it and who don't secure it? Especially when it is users and not "collectors" who pay the costs of recovery from identity theft? It's like someone demanding to borrow my car (something of value to me), getting drunk (not acting responsibly with my property), wrecking my car, and leaving me to pay the repair bill. It's a rotten deal. Any reasonable person would say, "You shouldn't borrow my car; get your own. If you are going to borrow it and you wreck it in a drunken stupor, you pay for it. The entire megillah."
 
&lt;Roger> Identity standards have been well established for the means of collecting and "connecting the bits" so that the necessary identity information can be protected and securely shared for legitimate purposes.  The danger is that, once the bits are connected for illicit purposes, they can spread at light speed through web infrastructure.  The identity industry is beginning to establish policy standards that go beyond simple interoperability of the technology.  Rules can be created so that there are secure electronic safeguards in place to ensure that only legitimate connections can be made, thereby significantly reducing the opportunity for identity theft.  Additionally, one can assure that the mechanisms for managing the data and performing risk analysis can be thoroughly audited.  Establishing, implementing, deploying, and auditing these standards-based solutions will add enormous confidence to those who are using web-based services.  And that will yield comparable market growth.  
 
&lt;Mary Ann> I like what I am hearing from you, Roger! Federated identity is a wonderful thing when there is a business purpose for linking my identities, as there so often is. As someone who is forever being asked to create another username and password for yet another website, I wish we had more of this where it makes sense. However, federated identity is most assuredly not "having a single persona that relies on an immutable non-secret for security." Only God and my mom - well, maybe only God - knows or should know all the different facets of my persona, or anybody's persona. I for one would like to keep it that way.
 
&lt;Roger> So, Mary Ann does your spleen feel sufficiently vented?
 
&lt;Mary Ann> On this topic, yes! Thanks for adding color, detail and expertise to the discussion, and for being part of the solution, not the problem.

Database Upgrade from 8i to 9i

Madan Mohan - Tue, 2007-07-31 01:53
Pre-Upgrade Tasks

1) Make sure that you have 9iR2 software (9.2.0 CD Dump) before starting the installation.

first need to download the software on the server. Following are the details of the software to be downloaded:

i. 9.2.0.1 for Solaris:
Disk1: Part# A99349-01
Disk2: Part# A99350-01
Disk3: Part# A99351-01
ii. 9.2.0.1 for Linux
Disk1: Part# A99339-01
Disk2: Part# A99340-01
Disk3: Part# A99341-01

2) Login to orxxxxxx user and make sure that you have minimum 4 GB free space in /xxxxxx/oracle mount point. If you do not have enough free space, you need to send the TAR to SA team for adding more space to /xxxxxx/oracle mount point.

3) Make sure that you have oraInst.loc file in the below given locations and it has 777 privileges over it. If the file is not there or it does not have 777 privileges, you need to send the TAR to SA team for creating the file or granting 777 on it.
a. On Solaris: /var/opt/oracle/oraInst.loc
b. On Linux: /etc/oraInst.loc

4) Look out for the oraInventory on your instance. As per EBSO standards the location of oraInventory is “/xxxxxx/oracle/product/oraInventory”. If it is not present in this location you need to search for it. Once you know the location of oraInventory and you have privileges to update oraInst.loc file, make sure that the contents of oraInst.loc is as shown below. If the file was already existing and had some other values, just update it as shown below:
inventory_loc=//oracle/product/oraInventory
inst_group=

5) Make sure that you have /igold symbolic link pointing to /xxxxxx on the file system.

Preparing the System for Upgrade

1) Declare blackout on all the Components of APPS Instance and shutdown all Middle-Tier services of the instance. Keep Database server and DB listener up.

2) Check the free space in SYSTEM tablespace and if it is less than 1 GB free, add another datafile to create free space. Similarly, make sure that you have minimum 750 MB free in RBS tablespace. One example of how to add datafile is given below.

SQL> select tablespace_name, round(sum(bytes)/1024/1024) free_space from dba_free_space where tablespace_name in (‘SYSTEM’,’RBS’) group by tablespace_name;

SQL> alter tablespace SYSTEM add datafile ‘/xxxxxx/oradata02/data02/systemxx.dbf’ size 1000m autoextend on next 25m maxsize 1800m;

3) Make sure that the value of maxextents for all Rollback Segments is Unlimited. Run the below given query to check this. The value of “32765” means the Unlimited size. If the value is less than 32765 then alter the rollbacks segment to make maxextents unlimited.

SQL> select segment_name, max_extents,status from dba_rollback_segs;
SQL> alter rollback segment rbsXX storage (maxextents unlimited);

4) Set the values of following parameters in initXXXXXX.ora file as given below.
db_domain =
aq_tm_processes = 0
job_queue_processes = 0
log_archive_start = false
_system_trig_enabled = FALSE

5) Search for any “event=” set in initXXXXXX.ora or ifilecbo.ora files. If you find any event, comment that entry. Also, you may not find some of the initialization parameters given above in initXXXXXX.ora file. In that case check the parameter in ifilecbo.ora file.

6) Alter the database to NOARCHIVELOG mode and shut it down. Also shutdown the DB listener.

$ sqlplus “/ as sysdba”
SQL> shutdown immediate
SQL> startup mount
SQL> alter database noarchivelog;
SQL> archive log list
SQL> shutdown immediate
SQL> exit
$ lsnrctl stop XXXXXX


7) Create new ORACLE_HOME and set environment for that.

a. Create new directory “920” in product directory for the new HOME
$ cd /xxxxxx/oracle/product
$ mkdir 920

b. Copy the environment file from old ORACLE_HOME (817) to new ORACLE_HOME (920)
$ cd /xxxxxx/oracle/product/920
$ cp ../817/.env .

c. Edit the environment file in new ORACLE_HOME and change all the references from “817” to “920” by performing a global replace in “vi”.
$ vi .env
:1,$ s/817/920/g

d. Edit “.profile” file and “.bash_profile” (only in Linux) and edit all the references of “817” to “920”

$ cd $HOME
$ vi .profile
:1,$ s/817/920/g
$ vi .bash_profile
:1,$ s/817/920/g

e. Log out from orxxxxxx user, login again and make sure that the following environment variables are pointing to new ORACLE_HOME i.e. “/orxxxxxx/product/920”.
$ echo $ORACLE_HOME
$ echo $LD_LIBRARY_PATH
$ echo $TNS_ADMIN

8) At this stage we are ready to perform our upgrade. Just review all the steps in these first 2 sections and make sure that you have followed all of them. Then proceed to next section and perform the upgrade.

Performing 920 Upgrade

1) Login to orxxxxxx user and make sure that the environment variables like ORACLE_HOME, TNS_ADMIN and LD_LIBRARY_PATH are pointing to new ORACLE_HOME of 920. Also, make sure that /igold symbolic link is pointing to /xxxxxx and oraInst.loc file has been correctly updated. All these things had been discussed in the previous sections of the document.

2) Start a Reflection X session and connect to orxxxxxx user using Fsecure SSH client. Run xclock to see if you can run GUI. If you are performing the upgrade from a remote location (from India) do not run the Installer from your own PC but use VNC Viewer to connect to a Desktop in the US and then run the upgrade from the US PC. In case of Your Place customers, the normal SSH session is enabled to run GUI Installers and there is no performance hit from any location. You can run the installer without opening any Reflection or VNC viewer.

3) Start “runInstaller” from Disk1 of 9.2.0.1 CD Set which has been downloaded earlier and choose the following options while installation:

a. File Locations:
ORACLE_HOME name: IGOLD920_HOME
ORACLE_HOME path=/igold/oracle/product/920
Do not give the actual location of 920 ORACLE_HOME (/xxxxxx/oracle/product/920) here. We are deliberately using “igold” as it helps in patching of cloned instances

b. Select a Product:
Oracle 9i Database 9.2.0.1.0

c. Type of Installation:
Enterprise Edition

d. Database Configuration
Software Only

4) Download 9.2.0.4 PatchSet (Patch# 3095277) and unzip it in a temporary directory and run below given cpio command. It will create a new Disk1 directory.
Solaris:
$ unzip 9204_solaris_release.cpio.z
$ cpio -idmv < 9204_solaris_release.cpio
Linux:
$ cpio -idmv < 9204_lnx32_release.cpio

5) Start “runInstaller” from /xxxxxx/oracle/product/oui directory to install 9.2.0.4 PatchSet files and choose the following options:

a. Files Locations:
Source Path: /Disk1/stage/products.jar
ORACLE_HOME name: IGOLD920_HOME
ORACLE_HOME path=/igold/oracle/product/920

b. Choose OUI installation and complete it. Exit the installer, do not choose continue with “Next Install”. You have to restart installer.

c. Start installer again with the same File Location values as given above and choose 9.2.0.4 PatchSet installation.

6) Relink Oracle executables to remove igold dependencies and verify that libraries being referenced after relinking are from correct ORACLE_HOME location and not from igold link.
$ cd $ORACLE_HOME/bin
$ ./relink all
$ ldd lsnrctl
$ ldd sqlplus
$ ldd oracle

7) Copy initXXXXXX.ora and ifilecbo.ora files from old ORACLE_HOME to new 920 ORACLE_HOME. Do not change the value of any initialization parameter; this will be done in later steps.
$ cd $ORACLE_HOME/dbs
$ cp ../../817/dbs/initXXXXXX.ora .
$ cp ../../817/dbs/ifilecbo.ora .

8) Perform the DB upgrade from 8.1.7 to 9.2.0 using the manual scripts as given below. These upgrade scripts may take 4-5 hours to complete. “startup migrate” statement will throw “ORA-32004: obsolete and/or deprecated parameter(s) specified” exception. At this point of time ignore this error it will be taken care in later steps. Once the upgrade scripts complete, query “dba_registry” table to make sure that Oracle components have been upgraded.
$ sqlplus “/ as sysdba”
SQL> startup migrate
SQL> spool db_upgrade.log
SQL> @?/rdbms/admin/u0801070.sql

Limit user sessions in Oracle

Hampus Linden - Mon, 2007-07-30 15:55
Developers sometimes enjoy configuring their JDBC datasources after their own likings, testing a performance issue by having a gazzillion threads to the database "just in case we need them".
Well in my opinion, if you need what is obviously too many threads, then there is a coding issue.
So to make people think twice before flooding a service with connections I've started limiting the number of sessions they are allowed to have.
Easy as always to do in Oracle. First we allow resource limits by setting the resource_limit to true, then we simply create a profile and assign that to the user. The profile can set the limit of how many session a user is allowed to have.

A little demonstration;
oracle@htpc:~$ rsqlplus "/ as sysdba"

Integer Series Generators: Multiple Integer Series (New SQL Snippets Tutorial)

Joe Fuda - Sun, 2007-07-29 13:30
The SQL Snippets "Integer Series Generator" section has been expanded to include new topics covering techniques for generating multiple integer series in a single query. Unlike previous topics which only demonstrated queries that created a single integer series, like 1,2,3,4, the new topics show how a query can generate a series like 1,2 for one row and 1,2,3 for another row in the same query.

Accessing Custom Forms after Upgrading To R12

Fadi Hasweh - Sun, 2007-07-29 03:23
I was checking customization upgrade subject since we faced it and I found this interesting note (451934.1)


The note is talking about how to make custom forms that where created and working fine on 11i to work the on R12.
And according to the note
"All custom forms that were build and working fine on releases 11i are designed and compiled using the Form Builder 6i, while the developer version for R12 is 10G.So you need to open the custom forms in Form Builder release 10G and compile them and save then upload them again."

I did not try the solution yet but thought of sharing it since many were asking bout this subject lately.
Also i found the (Custom forms does not work after upgrade to 12i) forum helpful

Data consistency and accuracy

Peter Khos - Fri, 2007-07-27 17:49
Earlier this week, a private contractor working for the City of Burnaby (a suburb of Vancouver) dug their backhoe into a high pressure oil pipeline (a video of incident) sending about 1,400 barrels of crude oil high into air covering the neighbourhood and eventually leaked out into the Burrard Inlet. It took half of an hour before the pipeline was switched off and two hours before the oil boom Peter Khttp://www.blogger.com/profile/14068944101291927006noreply@blogger.com0

Choice of desktop OS

Back in April of this year, I bought a new Dell AMD desktop which comes with Vista installed. I gave that a twirl for a month and thought maybe I should go with Linux so that I can install Oracle on a "proper" OS and also Vista applications are tough to come by.I am finding that Linux (I chose Ubuntu) has similar problems where I was not able to use the software that comes with my various Peter Khttp://www.blogger.com/profile/14068944101291927006noreply@blogger.com1

Remote debugging Code Tester

Jornica - Tue, 2007-07-24 12:04

Quest Code Tester for Oracle (Code Tester) helps you with defining test cases, generating test harnesses and presenting the test results in a structured way. Code Tester does not provide any features to debug your code. If you run into a red light situation when a test case fails, you have discover where the error is located. This means checking inputs and outcomes in order to exclude incorrect setup and incorrect initialization code. And of course checking your code, recompiling your (test) code and login again.

If this does not result into a green light, it is time to debug your code with a development IDE. As a result you have to transfer your test code into your development IDE. Wouldn't it be nice if you could enter debug mode seamlessly: when executing your test case the execution stops at a breakpoint and you can debug your code. The answer is: yes, you can. With SQL Developer you can remote debug your code within a test run.

The linking pin between Code Tester and SQL Developer is the package sys.dbms_debug_jdwp where jdwp stands for Java Debug Wire Protocol. This protocols needs a debugger process i.e. SQL Developer and a debuggee process i.e. Code Tester. The debugger listens for requests from the debuggee i.e. PL/SQL package procedure calls to connect_tcp and disconnect.

Setting up the debuggee
In Code Tester you have to modify the initialization section of your test case. Add the following code
dbms_debug_jdwp.connect_tcp(host => '127.0.0.1', port => 4000);
The first parameter is your IP address of the client where the Code Tester IDE runs (as seen from the database server you're connected to). Because I'm running Code Tester and Oracle XE on the same machine, I use the local host address 127.0.0.1. The second parameter is the default port. An alternative for the hard coded IP address is SYS_CONTEXT ('USERENV', 'IP_ADDRESS').

After the test case is executed, switch off remote debugging. Add the following code to the cleanup section:
dbms_debug_jdwp.disconnect;

Setting up the debugger
In SQL Developer login with the same user as Code Tester and right click on your connection, a context menu appears and select the 'Remote Debug' option. A small window with the title 'Debugger - Listen for the JPDA' (Java Platform Debugger Architecture) appears, enter the address or host name where SQL Developer should listen to connect. Use the same IP address as in dbms_debug_jdwp.connect_tcp. Also check if the port is the same.



Before switching to Code Tester again set a breakpoint in your code (and compile your code for debug) otherwise the debugger will not stop at your breakpoint. At last but not at least make sure the user has the debug connect session privilege and the debug any procedure when debugging other users objects.

Debugger meets debuggee
It is time to run your test with Code Tester. SQL Developer will stop on your breakpoint. Note: while debugging your code Code Tester will not respond. After stepping through your code press the resume button in SQL Developer to return to Code Tester. As an example I modified the code of the normal usage test case of the function qctod#betwnstr (see for an explanation and the source code How Quest Code Tester for Oracle can help you get rid of bugs in your PL/SQL procedures). In the picture below SQL Developer hits the breakpoint at line 13. In the data tab you can see all variables and their values.

This example shows how to use remote debugging with Code Tester. Instead of using SQL Developer as debugger you can also use Toad for Oracle or Jdeveloper. And also every front end can be used as debuggee for remote debugging as long the calls to dbms_debug_jdwp can be implemented. Let's start debugging!

In my last post, I mentioned that I was going to blog about the spat between Burleson and Lewis but decided not to BUT I left a comment on Kevin Closson's blog referring to the spat.
