APEX UT - Display Image in a List

Denes Kubicek - Mon, 2016-06-20 07:34
If using universal theme, we can switch from a classic navigation bar to a list and display it where usually a navigation bar is displayes - right top of the page. The problem with the list is that it will escape any html code in the list name. If we want to display an image, we will get the html code. To go arround that problem, we can use the "user defined attributes" for the lists and put the image into the "Badge Value". This list will then display the image almost as expected. We will need to apply additional css to make the background of the "Badge Value" transparent and to adjust the font to the rest of the navigation bar list:

.t-Button--navBar .t-Button-badge {background-color: transparent !important; font-weight: 400 !important; font-size: 1.2rem !important}

This is then how it appears:



Here, we can add the "Badge Value":



Finaly, here we can change our navigation bar from classic to list or oposite:

Patch analysis fails at step "Target Status" and at "Build Target Patch" for EM12cR5 GI+DB APR2016 Patches

Arun Bavera - Thu, 2016-06-16 14:10
Issue: Patch analysis fails at step "Target Status" and at "Build Target Patch" for EM12cR5 GI+DB APR2016 Patches
Requirement:

Agent-Side Monitoring 12.1.0.8.160531:(May 31, 2016) Patch 23217639
* Agent-Side Discovery 12.1.0.8.5: (November 30, 2015) Patch 22135601


Steps Taken:
 
1. We started with GRID Infrastructure PSU APR2016 Patch in the lab cluster 22646084 (12.1.0.2.160419).
During the EM Patch analysis we encountered mismatch between the targets configuration info collected from “EM Repository from agent” with “oplan” tool of OPatch.
Similar Bug(this issue  HAS having smallcase and UPPERcase with EM collection and Oplan collection, customer had uppercase shortname host in /etc/hosts)
BUG 20323468 - Run Configuration Compare fails with - invalid instances monitored by EM  -> BUG 21258331 - CONFIGURATIONCOMPARE SHOULD BE CASE INSENSITIVE REGARDING THE HOSTNAME
In our case we were seeing the discrapancies in targetname with FQDN and shortname


2. We then tried DB PSU 22291127 (12.1.0.2.160419), which failed in the step ‘Target Status Check’ which we determined as concurrency issue- we were able to overcome this by removing additional ClusterDBService and Patch analysis was successful for DB side patch only. We decided to create one more ClusterDBService to test again this DB PSU. If we retry this step one by one on each node we can overcome this concurrency.
Erros:Another datapatch session is currently running.
Waiting for that session to complete before continuing...
Queryable inventory could not determine the current opatch status.
Execute 'select dbms_sqlpatch.verify_queryable_inventory from dual' and/or check the invocation log /ora01/app/oracle/cfgtoollogs/sqlpatch/sqlpatch_54049_2016_06_16_14_37_26/sqlpatch_invocation.log for the complete error.
Prereq check failed, exiting without installing any patches.
Error Codes:ORA-20009: Job Load_opatch_inventory_1execution failedWe have a somewhat workaround, but to fully automate we need fix for:
a. BUG 22204310 - CANNOT INVOKE DATAPATCH -PREREQ IN A CONCURRENT FASHION 
b. Bug 19178275 - fixes concurrent access to QI when multiple DBs access it in a shared OH  - is not backported yet
c. Bug 20879709 - concurrency with dbms_qopatch apis with fixed table implementation  -  is not backported yet




3. We again tried troubleshooting GI PSU, we are able to find the root cause, as 2 of the nodes were referring to wrong Oracle Central Inventory. Where the EM patch analysis was failing during compare configuration step. We fixed this.
The GI PSU Patch plan failed at the last step: In the EMOMS.log related errors as:
2016-06-15 15:46:35,246 [RJob Step 250083] ERROR dpGenerator.MultiPatchProcessor logp.251 - 22646084{, root=/%emd_emstagedir%/p22646084_600000000009300_226_0/oracle, oracle=/%emd_emstagedir%/p22646084_600000000009300_226_0/oracle} 2
2016-06-15 15:48:26,137 [RJob Step 250083] ERROR dpIntg.BuildPrereqProcAndConfig logp.251 - Exception while building the prerequisite procedure
oracle.oplan.sdk.oplan.OPlanInternalException: Unsupported Action Type:oracle.opatch.system.automation.jaxb.CommandAction subtype:preRACPatchApplyshell
Error: oracle.opatch.system.automation.jaxb.CommandAction subtype:preRACPatchApplyshell



Analysis:
The first hit you get on this issue is: Bug 21919097 : The Prerequsite Checks Required by OPlan Fails With Unsupported Action Type  - Closed as not a bug due to issue in-à BUG 20950255 - UNABLE TO APPLY APR PSU VIA EM - FAILS AT ANALYSIS AND UNABLE TO PROCEED  -- This is fixed in  EM DB Plugin 12.1.0.8  ---- Which we have already applied

Another, fix which is required for this issue is in Patch:
Patch 21364690: Tracking bug to deliver one-off patch for oplan bugs 20978207 and 20995318 DB Plugin (OMS) 12.1.0.8.0
Action: Fix available at: https://support.oracle.com/epmos/faces/PatchDetail?requestId=19551356&_afrLoop=418222758860502&patchId=21364690&_afrWindowMode=0&_adf.ctrl-state=n3gg18298_1124 – We need to apply this patch




Summary:
We have two issue here:
4. Concurrency issue with “Target Status Check” step – We can check with support whether its related and get fixes for the BUGS: BUG 22204310, Bug 19178275 and 20879709
5. GI PSU failing in last but one step  - “building the prerequisite procedure “ - we applied the fix for 21364690 and it fixed the issue.

Enter your bets on Euro2016Challenge.eu now

Dimitri Gielis - Fri, 2016-06-10 05:55
Looks like I forgot to put on my blog also this year we created a bet site for the European Cup Soccer. Thanks to the people who reminded me to put this post on my blog :)

It all started in 2006 when I first created a site to promote Oracle Application Express (APEX). The site allowed to bet on the games of the World Cup. At that time everybody was using Excel files internally to put the scores together, enter the bets of the people... so I thought why not build it in APEX :) Oh the betting is for fun and honour ... so no money involved!

Since then every two years we have updated the site and enabled it again. Today almost 3000 people are playing with us. We changed a few times from url; first it was called DG Tournament, than the World Cup Challenge and this year it's the Euro 2016 Challenge.

So if you didn't put your bets in, there're a few hours left ... happy betting and that the best may win!


This year we (Belgium) have a chance to come far in the tournament, go go go Belgium! :)

Export your APEX Interactive Report to PDF

Dimitri Gielis - Tue, 2016-06-07 10:36
Interactive Reports (and Grids in 5.1) are one of the nicest features of Oracle Application Express (APEX) as it allows an end-user to look at the data the way they want, without needing a developer to change the underlying code. End-users can show or hide columns, do calculations on columns, filter etc.

Here's an example of an interactive report where highlighting, computation and aggregation is used.


More than once I get the question, how can I export this to PDF or print this Interactive Report?

Here're 3 ways of doing this:

1. Use your browser to Print to PDF

The challenge here's that you would need to add some specific CSS to get rid of the items you don't want to be printed, e.g. the menu, the header and footer and some other components like buttons.
Also if you have many columns, they might not fit on the page and the highlighting is not working when printed, but if you can live with that, it might be an option for you.


Here's the CSS you can use:

@media print {

  .t-Body-nav {
    display:none
  }
}


2. Use the download feature of the Interactive Report itself (Actions > Download > PDF)

This feature is build-in APEX and relies on a print server supporting XSL-FO; when using ORDS it will automatically work. If you're using Apache, you will need to configure a print server like BI Publisher or Apache-FOP.


When downloading to PDF, the result looks like this:

The PDF contains the data and we can specify a header, footer and how the columns look like, but we lost many features of the Interactive Report; no highlighting, no computation or aggregation.


3. Use APEX Office Print to print the Interactive Report in your own template defined in MS Word.

One of the unique features of APEX Office Print is that it's tightly integrated with Oracle Application Express and that it understands Interactive Reports as the source of your data.

Here're the steps:

- Create your template in MS Word and add {&interactive} tag where you want the Interactive Report to be


- Give your Interactive Report a static id:



- Add the APEX Office Print Process Plugin to your page and specify the template and the static id: 


And here's the result: 


I'm biased as we created APEX Office Print (AOP), but I just find it awesome :)
In your Word template you just add one tag, that's it!

In all seriousness, we would really want to hear from you if this feature works for your Interactive Report. You can try AOP for free for 100 days. We're trying to be smart and are doing automatic calculations of the column width, but we probably can improve it even more. We introduced this feature with AOP v2.0 (MAR-16) and improved it in v2.1 (MAY-16).

Requirements:
Customer has requirement to alert if the multipath count goes down from 4.

Command to get the count as privileged User:
multipathd list multipaths status | awk '{print $1"|"$4}'

Once you add this metric Extension as part of your Standard Template, only requirement is to have this executed as Privileged Named Credential  or give access to your normal user say 'oracle' the ability to execute multipathd restricting options in /etc/sudo or put that in a shell script in restricted folder and give access to execute only that shell script.

Oracle DBaaS CookBook using EM12c : MyNotes

Arun Bavera - Thu, 2016-06-02 10:15

Cloud/Super Administrator Tasks (EM CLOUD ADMIN Role)



Step 1: Decide with Architects and Cloud decision makers about the Service Catalog offerings


Business Catalog->Technical Catalog -> Service Catalog ( May be Subset of Technical Catalog)



A company can provide the Bronze and Silver tier in the self-service model but choose to deploy the Gold and Platinum tiers using native Oracle Enterprise Manager 12c capabilities.
Platinum Tier, should be implemented in its own reference architecture. In some cases, companies elect to provision these tiers using Oracle Enterprise Manager 12c native capabilities, as opposed to self-service




Step 2: Configure Software Library

Step 3: Deploy the necessary plug-ins. See Section 3.2, "Deploying the Required Plug-ins"


Step 4: Install the Management Agent on unmanaged hosts
so that they can be monitored by Enterprise Manager. See Section 11.2.1, "Adding Hosts".


Step 5: Configure Privilege Delegation for Database Servers Setup > Security > Privilege Delegation Configuring Privilege Delegation Settings


Step 6: Define Named Credentials Setup > Security > Named Credentials. Defining Roles and Assigning Users
In a DBaaS implementation the configuration of the named and preferred credentials is critical. In larger implementations of DBaaS, the preferred credentials are vital especially when using automation using emcli or when using the cloud framework in conjunction to the lifecycle management pack.


Step 7: Creating Cloud Users and Roles Setup > Security > Roles.
Quotas are assigned at the role level and users should be assigned to the roles based on the desired limits.
                 MYPROJECT_SSA_DB_DEV_USER_ROLE [ EM_SSA_USER is assigned to this role, also EM_USER and Public ]
               MYPROJECT_SSA_DB_PROD_USER_ROLE

Note: EM_CLOUD_ADMINISTRATOR(SYSMAN), EM_SSA_ADMINISTRATOR (SYSMAN), and EM_SSA_USER roles must have been created https://docs.oracle.com/cd/E63000_01/EMCLO/cloud_paas_setup.htm#EMCLO323>


Step 8: Create Self Service Portal Users Setup >Security >Administrators.
    MYPROJECT_CLOUD_USER as an example user or assign MYPROJECT_SSA_USER_ROLE to all MYPROJECT_DBA_USERS AD Group.


Step 9: Defining Databases Zones Setup > Cloud > PaaS Infrastructure Zones http://docs.oracle.com/cd/E24628_01/doc.121/e28814/cloud_paas_setup.htm#CHDBIBGB
Define and create zones to satisfy the Reference Architecture Design.
              1. DataCenter- A - Primary [ MYPROJECT_PaaS_DBZone_Primary_A ]
              2. DataCenter -B - Standby [ MYPROJECT_PaaS_DBZone_STandBy_B ]
Can be based on Geography (East/West),Lifecycle(Prod/Dev) or Functional ( ERP, DB, Siebel etc)
Placement Policy is maximum constraint for CPU and Memory on these Hosts
Refer: Adding Hosts  and  Creating a PaaS Infrastructure Zone


DBaaS Administrator Tasks (EM_SSA_ADMIN)


Step 10: Define Database Sizes: [ Only emcli option ]
emcli create_database_size -name=Small -description="Small size database" -attributes="cpu:2;storage:2;memory:1;processes:350"
emcli create_database_size -name=Medium -description="Medium size database" -attributes="cpu:3;storage:3;memory:1;processes:500"
emcli create_database_size -name=Large -description="Large size database" -attributes="cpu:4;storage:4;memory:2;processes:700"


Step 11: Defining Database Pools Setup >Cloud > Database and select "Database Pools"
a) Database pool name (select a distinct name that describes purpose of the pool in this example: DataCenter-A Linux64-11202-SI,
b) Provide Global credentials for an Oracle named credential. In this case, the grid and root credentials are optional,
c) Select the Hosts and database homes that will define the pool,
d) Select the PaaS Infrastructure Zone, Platform, database configuration and database version to be installed in the pool.




Step 12: Request Settings Setup >Cloud > Database and select "Request Settings" ( All settings at self service level)
• The amount of time in advance the self service user can schedule a request.
• The maximum amount of time for which a self service user can retain the instance.
• The amount of time after the completed self service create requests will be purged from the repository.


Step 13: Quotas Setup >Cloud > Database and select "Quotas" ( all settings at Role Level)
Using the Quota, the cloud administrator is able to assign to roles the following:
1. The amount of memory all the users assigned to the roles can consume.
2. The amount of storage all the users assigned to the roles can consume.
3. The number of databases all the users assigned to the roles can request.
4. The number of schema requests all the users assigned to the roles can request.
5. The number of Pluggable database requests all the users assigned to the roles can request.


Step 14: Defining Service Templates for Self Service Provisioning Setup >Cloud > Database and select "Profiles and Service Templates"





NOTE: Provide as much as details in description this is what SSA_USERS see when they request
Cloud DBaaS User Tasks [EM_SSA_USER is assigned to this role, also EM_USER and Public]


Step 15: Using Self Service Portal Enterprise > Cloud > Self-Service Portal or If the user has only SSA then when he logins he gets SSA Portal only not the normal view

Crowdsourced software development experiment

Dimitri Gielis - Thu, 2016-05-26 16:30
A few days ago I got an email about an experiment how to program with the crowd.

I didn't really heard about it before, but found it an interesting thought. In this experiment people will perform microtasks (10 minutes task), as a member of the crowd. People don't know each other, but will collaborate together. The system is distributing the work and supplies instructions. The challenge is in creating quality code that meets the specifications.

Job is still searching for some people to be part of the experiment, so I thought to put it on my blog, in case you're interested you find more details below and how to contact him.
