Check out the ADF content at this year's ODTUG KScope11 conference

Chris Muir - Fri, 2011-03-04 01:47
For all ADF developers, I'd like the chance to point out that this year's ODTUG Kaleidscope '11 conference in Long Beach USA has a substantial amount of ADF presentations. In fact quite a few active members of the ADF EMG will be presenting this year which is great.

For anyone who doesn't know much about the KScope events, ODTUG's conference series highlights real world experience with developers who are actually using Oracle products in the field. For anyone who doesn't consider themselves an expert, the KScope conference provides a great opportunity to learn from the pros tips n tricks on how to get your ADF applications from development to production

In turn for Fusion MiddleWare there's just on 60 sessions covering topics from SOA to WebCenter and of course ADF. Further incentives include streams dedicated to PL/SQL, the database, Apex and more. (Oh, and apparently it's sunny and warm in Long Beach and there's beaches too!)

If you're interested in the content, specifically the Fusion MiddleWare content, check out: http://kscope11.com/fusion ...then select either the Symposium or Presentations links.

We hope to see you there.

Oracle APEX 4.0 Cookbook

Marc Sewtz - Tue, 2011-03-01 16:39
Thanks to some recent train travel, I had a chance to catch up on some reading, and so I looked at the recently published Oracle APEX 4.0 Cookbook by Michel van Zoest and Marcel van der Plas. It's great to see more and more APEX books coming out, and of course there are already several excellent ones out there. This new one I found quite interesting due to the way it's been structured. The authors basically have chapters covering the main areas of interest, i.e. creating basic applications, themes, websheets, web serivces, APIs, etc. And then within each chapter, they have smaller sections that lay out, step by step, how to go about e.g. creating a form, creating a report, creating a theme, etc, all broken down into very manageable pieces. And in each section, they tell you what you need to get started, then walk you through the steps, and then provide some background info on how it all works. So I think this is the kind of book an APEX developer might put on his desk (or e-reader) to quickly look up specific features while they are developing their applications. I think this book provides a great value to both experienced APEX developers and developers who just recently got started. It's not necessarily targeted towards complete beginners though, i.e. it's not so much an introduction into APEX as the authors pretty quickly get into more advanced features, like APIs, AJAX, JavaScript, etc. So for anyone looking for an APEX book they can use to quickly look up certain features, and how to use them, this book is doing an excellent job.

Games (Asian) Indians Play

Khanderao Kand - Mon, 2011-02-28 21:21
I recently read this book,"Games Indian Play". This book is not about Indian games like Kho-Kho, Kabbadi etc. But it is about "why do Indian behave how they behave". To be precise, the sub-title of the book is "">Why we are the way we are". The author, Raghunathan, as used his studies on "Game Theory and Behavioral Economics" to make sense of Indians behavior. Its a though provoking book which uses "Prisoners Dilemma", the famous problem from game theory, to eloborate how Indians are 'rational' but thier self-centered rationalism undermines their long term as well as community interests. His examples cover day to day scenarios covers almost everyone, individuals, politicians, or community by and large. At the end of the book, the author tried to propose crux of "Bhagwat Geeta" as a solution to behavior and explained it in the context of the game theory problem.

I'm Totally Lost: Which Conference Do I Go To for Hyperion and Oracle EPM/BI Content?

Look Smarter Than You Are - Mon, 2011-02-28 17:02
The final Hyperion Solutions conference (the great big conference Hyperion used to put on with non-stop Hyperion content and over 4,000 attendees) was in the spring of 2007.  Back then, everyone knew which conference to attend, because there was only one national conference (Solutions) and then a whole lot of regional HUG (Hyperion User Group) meetings.  But then Oracle bought Hyperion and immediately disbanded the conference leaving the user community in disarray.

There are now several options depending on what you're looking for.  While I could attempt to make some sense out of the whole conference jumble in a blog post, I decided it would be better explained in a webcast.  To that end, I'm devoting two webcasts this week to the question “Now that the Hyperion Solutions conference is gone, which conference should I attend?”

I'm going to compare the benefits of the better known 2011 conferences:

I'm in a unique position to do this, because I don't work for Oracle and I have some ties to every one of these events (so you could say that while I'm biased, I realize the value each one can bring to the right audience).  Usually, our webcasts are only open to Oracle customers (not partners) but in this case, I want everyone to know why you'd want to go to each of the conferences so they don't find themselves wasting money at a conference that's totally not right for them.

Click on the links below to sign up for either Tuesday or Wednesday's webcast:

I will spend around 45 minutes covering all the conferences and then take questions from the audience.  Before you sign up for one of the conferences, devote 45 minutes of your life to making sure you won't find yourself trapped in the 7th circle of hell (otherwise known as stuck at a conference you hate).

Direct NFS Clonedb

Yasin Baskan - Thu, 2011-02-24 06:47
Direct NFS Clonedb is a feature in 11.2 that you can use to clone your databases. Kevin Closson explains what it is in this post. In his demo videos he is using a perl script to automate the process of generating the necessary scripts. That script is not publicly available as of today but the MOS note 1210656.1 explains how to do the clone manually without the perl script.

Tim Hall also has a step by step guide on how to do the cloning in this post. He also uses the perl script mentioned above.

We have been testing backups and clones on Exadata connected to a 7410 ZFS Storage Appliance, I wanted to share our test on Direct NFS Clonedb. This test is on a quarter rack x2-2 connected to a 7410 storage via Infiniband. A RAC database will be cloned as a single instance database and the clone database will opened in one db node.

Enable Direct NFS on Exadata

For security, as of today default Exadata installation disables some services needed by NFS. To use NFS on Exadata db nodes we enabled those services first.

service portmap start
service nfslock start
chkconfig --level 345 portmap on
chkconfig --level 345 nfslock on

Recent Exadata installations come with Direct NFS (dNFS) enabled, you can check if you have it enabled by looking at the database alert log. When the database is started you can see this line in the alert log if you have dNFS enabled.

Oracle instance running with ODM: Oracle Direct NFS ODM Library Version 3.0

If it is not enabled you can use this command after stopping the database to enable it.

make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk dnfs_on

Mount the NFS share

I am assuming 7410 is configured and NFS sharing is up on it at this point. To mount the NFS share you can use a mount command like this on Exadata db nodes.

mount /backup -o rw,bg,hard,intr,rsize=131072,wsize=131072,intr,nodev,nosuid,actimeo=0

Back up the source database

You can use OS copies or RMAN image copies to back up the database for use in the cloning process. Here are the commands we used, do not forget to create the target directory before.

sql 'alter database begin backup';
backup as copy database format '/backup/clone_backup/%U';
sql 'alter database end backup';

Prepare the clone db

To start the clone database we need an init.ora file and a create controlfile script. You can back up the source database's control file to a text file and use it. In the source database run this to get the script, this will produce a script under the udump directory (/u01/app/oracle/diag/rdbms/dbm/dbm1/trace in Exadata).

SQL> alter database backup controlfile to trace;

Database altered.

After editing the script this is the one we can use for the clone database.

  GROUP 1 (
  ) SIZE 4096M BLOCKSIZE 512,
  GROUP 2 (
  ) SIZE 4096M BLOCKSIZE 512,
  GROUP 3 (
  ) SIZE 4096M BLOCKSIZE 512

/u01/app/oradata/clone is a directory on the local disks, you can also use NFS for redo logs if you want to. The DATAFILE section lists the image copies we have just produced using RMAN. You can get this list using this sql, be careful about the completion time because you may have previous image copies in the same directory.

select name,completion_time from V$BACKUP_COPY_DETAILS;

Now we need an init.ora file, we can just copy the source database's file and edit it.

SQL> create pfile='/backup/clone.ora' from spfile;

File created.

Since the source database is a RAC database you need to remove parameters related to RAC (like cluster_database, etc...). You also need to change the paths to reflect the new clone database, like in the parameter control_files. Here is the control_files parameter in this test.


I also use a local directory, not NFS, for the control file.

There is one parameter you need to add when cloning a RAC database to a single instance database.


If you do not set this parameter you will get an error when you try to open the clone database with resetlogs. MOS note 334899.1 explains why we need to set this. If you do not set this this is the error you will get when opening the database.

RMAN> sql 'alter database open resetlogs';

sql statement: alter database open resetlogs
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of sql command on default channel at 02/22/2011 16:13:07
RMAN-11003: failure during parse/execution of SQL statement: alter database open resetlogs
ORA-38856: cannot mark instance UNNAMED_INSTANCE_2 (redo thread 2) as enabled

Now we are ready to create the clone database.

Create the clone db

After preparing the init.ora file and the create controlfile script we can create the database.

export ORACLE_SID=clone
SQL> startup nomount pfile='/backup/clone.ora';
ORACLE instance started.

Total System Global Area 3991842816 bytes
Fixed Size                  2232648 bytes
Variable Size             754978488 bytes
Database Buffers         3087007744 bytes
Redo Buffers              147623936 bytes

SQL>  @cr_control

Control file created.

Now we need to rename the datafiles and point them to a NFS location we want. dbms_dnfs is the package needed for this.


The first parameter to dbms_dnfs is the backup image copy name we set in the controlfile script, the second parameter is the target filename which should reside in NFS. You can create this script using the following sql on the source database.

select 'dbms_dnfs.clonedb_renamefile('''||b.name||''',''/backup/oradata/'||
from v$backup_copy_details b,dba_data_files d
where b.file#=d.file_id
and b.completion_time>sysdate-1/24;

If you have multiple image copies be careful about the completion_time predicate. In this example I am looking at the image copies of the last hour.

If the target location in the dbms_dnfs call is not on NFS here is what you will get:

SQL> exec dbms_dnfs.clonedb_renamefile('/backup/clone_backup/data_D-DBM_I-1222199824_TS-USERS_FNO-10_b1m59uem','/u01/app/oradata/clone/users.275.741357121');
BEGIN dbms_dnfs.clonedb_renamefile('/backup/clone_backup/data_D-DBM_I-1222199824_TS-USERS_FNO-10_b1m59uem','/u01/app/oradata/clone/users.275.741357121'); END;

ERROR at line 1:
ORA-01511: error in renaming log/data files
ORA-17513: dNFS package call failed
ORA-06512: at "SYS.X$DBMS_DNFS", line 10
ORA-06512: at line 1

I got this error in my first try and searched in MOS and Google for some time with no results. Then I realized that my target locations was not on NFS but was on local disk.

As we renamed the datafiles and they are pointing at the NFS location, now we can open the clone database.

SQL> alter database open resetlogs;

Database altered.

At this point we have a clone database ready to use.

The target directory we used shows our files.

ADF BC: Creating an "EXISTS" View Criteria

Chris Muir - Thu, 2011-02-17 19:10
The EXISTS keyword in SQL queries is an efficient mechanism for returning record sets from one dataset when they exist in another dataset. For example we can write queries like:

SELECT org.org_id, org.name FROM organisations org WHERE EXISTS
(SELECT 1 FROM events evt WHERE evt.org_id = org.org_id
AND evt.contact_name = 'Eddie Harris')

....which returns all organisations which have a related event whose contact is Eddie Harris.

ADF Business Components in JDeveloper 11g allow the creation of EXISTS subqueries via the View Object named View Criteria feature. They're easy to implement if you already know how to create View Criteria, as long as you know one small trick.

Default Business Components

Given the SQL query above using the one-to-many organisations-to-events example, imagine we have default Entity Objects (EOs), EO Associations, View Objects (VOs) and VO Links, as seen in this picture:

View Object Link Accessors

When created via the Business Components from Table wizard, the VO Link OrgEvtFkLink created, based on the EO Association OrgEvtFkAssoc, will include Accessors options under its Relationship tab in the VO Link editor:

If you select the pencil icon next to the Accessors options it reveals the View Link Properties dialog:

....from which you can see the "Generate Accessor" option selected for the "In View Object: Organisations View". While the selected state is the default option when created, it's this option which is essential for setting up the EXISTS View Criteria.

View Object View Criteria

Once you've ensured the Accessor option is set as described above, when you create a new View Criteria for the View Object, Organisations in our case, we configure the View Criteria as follows. First in the Create View Criteria dialog we should change the View Criteria name to something more suitable to reflect what the View Criteria will do for us:

Next select the Add Criteria button, which will create the basis of the expression used by the query:

On selecting the Attribute drop down, you'll discover a list of attributes from the OrganisationsView VO. In this list you'll note an attribute called "EventsView". This attribute is only available because of the options you configured in the View Object Link Accessors above. If you hadn't gone with the default options, the EventsView attribute would not be available, and you would not be able to create the EXISTS View Criteria:

With the EventsView Accessor selected the dialog for the first time shows the EXISTS clause:

The only think left to do is to select the Criteria Group expression of the EXISTS statement, in the example above this is the "Event No =" option, and change this using the supplied options in the fields below, to the actual expression we want to use in the EXISTS clause. From our example this is matching the Events Contact Name to a String:

Once completed in the right hand side you can see the EXISTS subquery that the View Criteria will apply to the OrganisationsView VO when executed.

Note I've also turned off the Ignore Case and Ignore Null Values options.


In the Business Components Browser, on opening the OrganisationsView, and selecting the View Criteria via the Find button, we're first prompted for a value for the bind variable:

...which once supplied, returns the only matching Organisations record:


Thanks to Eddie Harris at SAGE Computing Services for revealing the technique.

Whatever happened to Fusion Applications?

Andrews Consulting - Thu, 2011-02-17 12:48
Oracle Fusion Applications were announced with great fanfare at an event at San Francisco City Hall over five years ago.  The announcement created a high enough level of concern and confusion that a year later Oracle introduced the concept of “Applications Unlimited” – a promise to keep the traditional applications (including JDE and PeopleSoft) viable […]

Neighboring Siblings?

Ramkumar Menon - Wed, 2011-02-16 09:30


Found an Interesting observation on C.M.Spielberg McQueen’s Blog – XPath 1.0 describes, amongst other axes, ones that allow access to immediate parent and immediate child nodes, as well as access to ancestor and descendant node-sets, but does not provide for immediate siblings – The only way to access these are via predicates – preceding-sibling::*[1] or following-sibling::*[1], and not explicit next-sibling and a previous-sibling axes.


It’s Conference Season!

Cary Millsap - Mon, 2011-02-14 16:59
My favorite mode of life is being busy doing something that I enjoy and that I know, beyond a doubt, is the Right Thing to be doing. Any hour I get to spend in that zone is a precious gift.

I’ve been in that zone nearly continuously for the past three weeks. I’ve been doing two of my favorite things: lots of consulting work (helping, earning, and learning), and lots of software development work (which helps me help, earn, and learn even faster).

I’m looking forward to the next four weeks, too, because another Right Thing that I love to do is talk with people about software performance, and three of my favorite events where I can do that are coming right up:
  • RMOUG Training Days, Denver CO — I leave tomorrow. I’m looking forward to reuniting with lots of good friends. My stage time will be Wednesday, February 16th, when I’ll talk about material from my new “Mastering Performance with Extended SQL Trace” paper. 
  • NoCOUG Winter Conference, Pleasanton CA — I’ll be in the east Bay Area on Thursday, February 24th presenting the keynote address where I’ll discuss whether Exadata means never having to “tune” again and then spending two hours helping people to think clearly about performance.
  • Hotsos Symposium, Irving TX — I’ll present “Thinking Clearly about Performance” on Monday, March 7th. I love the agenda at this event. It’s a high quality lineup that is dedicated purely to Oracle software performance. This is one of the very few conferences where I can enjoy sitting and just watching for whole days at a time. If you are interested in Oracle system performance, do not miss this. 
Happy Valentine’s Day. I shall hope to see you soon.

Oracle EPM - Looks Like March

Look Smarter Than You Are - Mon, 2011-02-14 00:38
I don't work for Oracle.  Everything you see below is what I've heard said in public forums followed by some speculation of my own.  Oracle not only does commit to release dates, they don't even commit to specific future functionality.  For that matter, they won't even go on the record that there will actually be any future releases of products.  So take this whole entry for the best guess that it is. 

Why Do I Care About a Little Dot Release?
Based on the disclaimer above, I have been really hesitant to go on the record with any information about Oracle EPM (sometimes called "Talleyrand SP1" or "11.1.2sp1" or "The Patch" or "The Migration Patch" or "The Dot Release" although personally I like calling it "Waiting for EPM Godot").  The initial release of 11.1.2 dates back to April 2010 (yup, we're going on 10 months now) and there's still not an official service pack.  That doesn't mean there haven't been bug fixes.  They just slip them in as minor fix releases (like and the rest).  What we're really waiting for are some of the things that should be in

  • Bug Fixes.  Supposedly, all of the big show stopper bugs (like some of the Life Cycle Management issues and the almost complete unusability of the EAS fat client) are fixed in this release.
  • Migration. was released with no migration tools from earlier releases.  It was what was called a "greenfield release."  In other words, you could install it, but you couldn't get there from any earlier version.  Now my company like many others have done several "upgrades" to 11.1.2 of as many parts as we can, but officially, there's no way to migrate to 11.1.2... until  This version should have wizards and conversion utilities to migrate from multiple versions including 9.2, 9.3 and 11.1 (well, specific point releases of those).  In other words, you'll finally be able to do a supported migration and it should be easier than the manual methods we're doing now.
  • Wider Server Support. was released with support only for Oracle WebLogic 10.  Unlike earlier versions, it did not support Apache Tomcat nor IBM Websphere.  Now the good news was that Oracle was kind enough to issue a limited use WebLogic license.  The downside obviously was if you were not already a WebLogic shop.  Taking on a new application server infrastructure isn't easy.  The patch should support Tomcat and Websphere as well as Windows 2008r2 from an OS standpoint.  While it's on the client not server side, also expect to see Office 2010 support in 11.1.2. 
  • Performance Improvements.  With all the new functionality in EPM 11.1.2 (especially in Hyperion Planning), some things just aren't very speedy.  Development has said publicly that they are working on improving the speed of many of these new features including workflow and the new drag-and-drop forms designer.
Any New Functionality?
The four items above are as close to 100% definite as you can get.  They might change the specific versions you're allowed to upgrade from (current rumor is 9.2.1, 9.3.3,, and 11.1.2) but there will be lots of bug fixes, a migration path, wider server support, and performance improvements in most assuredly.  Where we get into a grayer area is, like the iPad 2, when we start speculating about any new features of functions in the release.  So here's what may or may not be in there (and don't base any buying decisions off my wild ass speculation):
  • Data Relationship Management.  This is straight from Oracle themselves, so it's very likely to be in there.  From the excellent though sporadically updated "Versioned Hierarchy of Reality" blog (ya, I'm one to talk), should contain:
    • Performance Improvements
    • Upgrade Support
    • Console Improvements
    • Property Namespaces
    • Single Sign On
    • URL-based Navigation
    • Job Status and Cancellation
    • Action Script Options
  • Disclosure Management.  Both Disclosure Management and Financial Close Management saw their initial releases in 2010.  As such, they should both be seeing substantial functionality improvements as Oracle tends to do in dot releases after the initial major release.  For Disclosure Management, the only major improvement I've publicly heard multiple times is for the UK folks: the ability to do XBRL income tax returns for HMRC.
  • Financial Close Management. It looks like the main improvements to HFCM (Hyperion Financial Close Management) have to do with direct integration to PeopleSoft.  Expect to see direct PeopleSoft 9.0 and 9.1 integration with AP, AR, BI, AM, and GL into HFCM.  For details, scroll down to page 17 of a presentation Oracle delivered to the NorCal OAUG. Looks like Oracle eBS integration won't make it into the release of HFCM but should be out by the end of 2011.
  • Smart View.  There will either be a bunch of improvements to Smart View in this release or they'll delay them to A lot of the new Smart View features we've seen demoed in the last year have to do with a new look for Smart View that makes it look a whole lot like Essbase classic (such as the ability to hide the POV). I'm expecting that these User Interface improvements will actually make it into, but I wouldn't bet on it.
The ones above are what I would be willing to wager make it into  There will doubtless be some minor improvements that I'll try to detail once the product makes it out the door.  As for some of those other big development things you've been hearing about (like custom dimensionality in HFM, account reconciliations in HFCM, project planning module for Hyperion Planning, micro-costing in HPCM, etc.) is probably going to end up waiting until  The most recent public EPM roadmap presentation from Oracle (scroll down to page 12) seems to reflect that other big items are being held.

So When Does It Come Out?
Talk about burying the lead.  The post is almost over and I'm just now getting to what I mentioned in the subject line.  Every person who's talked about release dates to this point has been wrong.  It went from August to fall to October to 2010 year end to January to "when Dallas freezes over the same week they host the Super Bowl."  Well, we all thought that was never going to happen, but then last week leading into the Super Bowl festivities, Dallas spent 100+ hours below freezing and it snowed several inches too.  So recognizing an apocalyptic sign, I reached out to a very high up source in Oracle EPM development...

... and was told March.  Further, the person  was almost willing to guarantee it if I promised to not mention her/his name.  "March?" I asked incredulously, because I had frankly lost all belief in release dates for  Development then explained to me why has been delayed for so many months.  And here's the thing: it's actually not development's fault nor legal's fault nor sales nor marketing nor any of the other groups that would tend to cause holdups like this.

No, it seems to be because of Fusion.  Oracle EPM is part of the Fusion Middleware team, and it is built on several other Oracle technologies both Fusion and otherwise.  The delay is because one of the key technology "tentpole" components in Oracle EPM coming from the Fusion side keeps changing.  Every time that underlying technology changes how it's implemented, they have to go modify the code for Oracle EPM.  In other words, EPM is just sitting there waiting for the tentpole technology to stop changing.

March, Seriously?
So how did development come up with March?  It seems that there's been a line drawn in the sand and that supporting Fusion tech will be finalized this month (February) which makes sense since it's the last month of Oracle's quarter.  Then it's just a quick change to Oracle EPM, some regression testing, and voila: Oracle EPM will finally be released.  That said, I'd bet on March 31 to be a whole lot more likely than March 1.

I know a lot of you will be waiting until the patch comes out, but please don't blame me if the date slips again (but give me kudos if I turn out to be right).  My infrastructure team at interRel is gearing up for all our clients that have managed to be dissuaded from going to 11.1.2 until the patch comes out, so we're concluding that this delivery date is real.  We're expecting busy times in March and April with all the migrations.  Keep watching here, and I'll let you know when finally shows up on edelivery.oracle.com.

How to call Oracle Reports server on cross domain

Branislav Nemec - Sun, 2011-02-13 10:14
If you (or a member of your team) are an Oracle Reports developer you can leverage your Reports skills also with ADF Faces applications. Since Oracle Reports server is part of Oracle Application Server 10g R2 and ADF Faces applications require Oracle AS 10g R3 you might find yourself in need to call the Reports server from different domain. It also might be the case of very scalable infrastructure when you have different parts of Oracle AS (infrastructure, portal, reports, ADF applications) on different servers.

Blog improvement for Linuxies

Branislav Nemec - Sun, 2011-02-13 10:14
Some visitors of my blog complained they couldn't find links to showcasts. I guess that those running Linux cannot see the video plug-in area where video in wmv format should be being played. So I decided to alternate each video also in form of flash and provide link to the separate page with Camtasia flash player. btw. I am using ADF Faces component objectMedia that has no support for flash format (at least for me it doesn't work). I hope it will have in the future. I hope it will be ok also for Linuxies... sorry again for inconveniences

Intergation of Oracle Maps and ADF Faces

Branislav Nemec - Sun, 2011-02-13 10:13
Oracle Maps is a part of Oracle Application Server MapViewer - the tool that visualize spatial data stored in Oracle Database using Oracle Locator or Spatial. What I like very much on Locator/Spatial is that I, as a GIS non-expert, can use Locator/Spatial just through SQL. Oracle Maps has a rich JavaScript API so with it we even don't need SQL to visualize spatial data. Since it is JavaScript client, we can integrate it to HTML/JSP/JSF/ADF Faces application. Furthermore it is based on AJAX technology and uses Map Cache server so you can develop "google like" maps.

Af:table - how to show totals of columns

Branislav Nemec - Sun, 2011-02-13 10:13
Current af:table component has one lack. You cannot simply show total sum of column. After a bit of googling I have found this nice solution from Frank Nimphius "ADF Faces: Compute totals of selected rows in a multi select table" . In my demo you can see the simplest way how to just show total of a column.

Graph in ADF Faces

Branislav Nemec - Sun, 2011-02-13 10:13
In the upcoming version of ADF Faces 11g we will have JSF graph component but so far we don't have. So we must use either third party JSF graph component or integrate Oracle BI Graph Bean. The video shows how to integrate BI Graph Bean into ADF Faces application via non JSF JSP declaratively using JDeveloper wizard.

Passing parameter from Oracle Maps to ADF Faces page

Branislav Nemec - Sun, 2011-02-13 10:12
Oracle Maps JavaScript API provide us with info window where we can show data related to feature of interest we click on. But if we want to show more complex data the simple bubble is not enough. In this case we can show some basic data in info window and the additional data in new browser window where we pass parameter to recognize our object and use it in the business logic.
