OOW 2009 1st report

Wed, 2009-10-14 00:03
It’s all about innovation that what Larry Ellison/Oracle and Scott McNealy/Sun said at the opening key note. I arrived to san Francisco for oow 2009 and I have to admit it’s a butifaul place. The organization of the oow is more than perfect so far. I did my registration online at moscone center and even thought there were thousands doing registration at the same time the registration process did not take more that 5 min. it was all online and automated. Meeting some of oracle team/employees was they were very friendly and helpful. Attending the unconffrance session was very good experience I attended Michael taylor session (Hyperion 11.1.1.3 on Linux Live Demo) and Fundamentals of Performance (Oracle ACE Director Cary Millsap). Attending ahmed al-omari session was a very good experience to me it was a Q&A session which was very helpful really. Also tom kyte session was great too I cannot put every thing in one post but more to come soon I will post some video and pictures I took from the event here soon If anyone who is reading this blog at the conference it’s a great chance to meet please drop me a line.


The Unconference sessions













the games area were people can have some fun

more to come soon.

Cloning 11i with 10g database (you may need a patch)

Sun, 2008-03-16 10:56
I faced the following error while configuring database when cloning apps 11i with 10g database and it happens directly after entering the path of the third data_top (by the way the script will always assume you have 4 data_tops even if you have more/less data_tops)

StackTrace:
java.lang.NullPointerException
at oracle.apps.ad.context.CloneContext.createContextFileForDbhomes(CloneContext.java:2816)
at oracle.apps.ad.context.CloneContext.getInputFromUsers(CloneContext.java:1485)
at oracle.apps.ad.context.CloneContext.doClone(CloneContext.java:627)
at oracle.apps.ad.context.CloneContext.main(CloneContext.java:6085)

On metalink there was the solution on Note:427981.1 Subject:RC-50004 When Specifying DATA_TOPS While Cloning a 10.2 Database
And the solution is to apply a patch with a version of CloneContext.java above 115.203. the following are possibilities patches

Patch 5473292, Patch 5732291, Patch 5604818, Patch 5456078, Patch 5474116

Well I did not do that because this means that I have to apply the patch and recopy the database, which take time.
So I recreate the database manually using control file. And when try to open the database I issued
SQL>alter database open resetlogs;
It failed with the following
alter database open resetlogs
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/ora_dev/data/system01.dbf'
Even though the database was completely down when I copied it I faced this error the good thing is 2 days ago I was reading bas post http://basklaassen.blogspot.com/2008/01/recover-database.html
I followed the steps for recovery and provided the path to my online log files and the recovery completed successfully.
Next down time for the production database for sure I will apply one of the patches above.

Hope that helped

Add new node to apps 2

Wed, 2008-02-13 09:30
Please read http://oracle-magic.blogspot.com/2008/02/add-new-node-to-apps.html before reading the steps below,

After finishing configuring the clone instance by running adcfgclone.pl I had to run the adaddnode.pl script according to note 464018.1.
While running adaddnode.pl I faced the following error
ERROR at line 1:
ORA-00001: unique constraint (APPLSYS.AD_APPL_TOPS_U2) violated
ORA-06512: at line 16

I followed note 394615.1 to solve it and after I did the steps in the note I run adaddnode.pl again and I faced error related to AD_TIMESTAMPS_U1 I checked on metalink but I could not find anything then I search on google and found post by dave http://newappsdba.blogspot.com/2006/09/dont-hit-ctrl-c-while-running.html from his post I took a backup the ad_timestamps and then truncate it after that I run adaddnode.pl and it completed successfully.
Then I updated the xml file to have only the forms and web servers running on this new node following the same note 464018.1 I run autoconfig the start the service on both nodes a now able to access both nodes.

What I want to do now is to configure web cache as load balancer also I want to implement Step 2.4.1.2. Implement Forms Listener Servlet Support from note (Advanced Configurations and Topologies for Enterprise Deployments of E-Business Suite 11i) Note:217368.1 in order to have Forms Server Load Balancing, so when one form server go down in one node users will be connect to the other forms node.Because the current configuration if I am connect to webnode1 and forms on that node is down I will not be able to connect to forms and I will receive an error but if load balancing is implemented it will take me to the other working forms server node.

Add new node to apps

Mon, 2008-02-04 11:04
A customer want to add new web/forms node to his current multi-node apps 11.5.10.2 production system also we have to configure a web cache load balancer.
The current system is 2 nodes (db node, apps tire node).
I am currently doing the configuration on test environment, I followed note (
How to Add a New Node to The Application Tier, and Make It a Web Server Node Only, Note: 464018.1 same as instructions of "Part 4: Adding a new node to an existing system" under "Section 4: Advanced Cloning Options" of Note 230672.1"Cloning Oracle Applications Release 11iwith Rapid Clone".

I am currently cloning the apps tire to the new server after that I will run adcfgclone.pl then adaddnode.pl in order to configure it. One important note is to disable SQL*Net Access so that the new node can access the database.
after that i will try to configure the webcache as load balancer.
I will update you once done.

Enjoy

DISPLAY, Audience, IE and page cannot be displayed

Sun, 2007-09-02 07:34
For the last 45 days my end user faced an issue accessing the following path
Audience super user responsibility ->AUDIENCE ADMINISTRATION DASHBOARD and then click link------->Audience Workbench

It will work fine if the user don’t have and lists attached to his workbench, if he created a list he will not be able to access the audience workbench, there will be no errors but after 7 minutes the user will receive the page cannot be displayed and no errors in the error_log or jserv.log.

After a long investigation and many OWCs and after creating a bug a smart engineer form oracle support (libby) and from her first update figure out that it might be a display issue since accessing the (Audience Workbench) when a list is attached the page will draw a chart for that list, so she gave me the following update to try

1.Please create a small jsp say testXServer.jsp and place it in the OA_HTML directory for the env and point your browserto it. If the DISPLAY setting is okay you will see a message stating the same, else you will see an exception.

please check the note to get the code for the test file (note 456424.1)

2. Invoke the jsp using the following url :http://.us.oracle.com:/OA_HTML/testXServer.jsp

3. If the DISPLAY is pointing to a valid xserver then the page will come up very quickly with the success message

When I tried the page it returned the page cannot be displayed error so I figured out that there is something with the display, I fixed the display issue and now every thing is working fine.

A new note has been created under metalink with the number (456424.1) for that issue.

Hope that helped

Handy script to find out eligible workflow data for purging

Tue, 2007-08-07 02:33
I have the "purge Obsolete Workflow Runtime Data" concurrent request scheduled to run on a weekly basis but I find out that this request is not purging all data that can be purged, so I searched metalink for similar cases and found more that one note talking about the same issue, anyway one of the notes (165316.1) (bde_wf_data.sql - Query Workflow Runtime Data That Is Eligible For Purging) has the bde_wf_data.sql script that can be downloaded from metalink, this script will create a bde_wf_data.lst file that looks like a script but it needs some cleansing, the script has commands like the following
Ex.

exec WF_PURGE.ITEMS('POAPPRV','10289-20146',SYSDATE,FALSE);
exec WF_PURGE.ITEMS('REQAPPRV','4941-13066',SYSDATE, FALSE);

Which will purge data eligible to be purged, also at the end of the .lst file there are statements to delete/build the tables stats for the following tables
WF_ITEM_ACTIVITY_STATUSES, WF_ITEM_ACTIVITY_STATUSES_H, WF_ITEM_ATTRIBUTE_VALUES, WF_ITEMS, WF_NOTIFICATIONS, WF_NOTIFICATION_ATTRIBUTES

Since the script do a lot of purging/delete form those tables so the stats needs to be build again

EXEC DBMS_STATS.DELETE_TABLE_STATS(ownname=>'APPLSYS',tabname=>'WF_ITEM_ACTIVITY_STATUSES');
EXEC FND_STATS.GATHER_TABLE_STATS(ownname=>'APPLSYS',tabname=>'WF_ITEM_ACTIVITY_STATUSES',percent=>10,granularity=>'DEFAULT');

And during the search I found note (144806.1) (A Detailed Approach To Purging Oracle Workflow Runtime Data) which I recommend so much for reading

have a nice free bugs day

Accessing Custom Forms after Upgrading To R12

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

How we solved a (ORA-02049 Timeout: Distributed Transaction Waiting for Lock) on our Apps Customized module

Sun, 2007-07-22 05:00
We have a customized Point of Sale module that is integrated with our Apps standard CRM and financial modules; we faced a serious issue on this customized module that is when users are trying to sale through this module they receive an ORA-02049 Timeout: Distributed Transaction Waiting for Lock, which require them to keep trying until they make the sale. This error used to show on daily basis on the peak hours only but we could not tell what the cause of it, simple search of the error on metalink return note 1018919.102 that advices that we should increases the distributed_lock_timeout value in the INIT.ORA file the default value was 60 seconds so we increased it to 300 seconds even though we don’t have any distributed transactions on the system all the transactions were local. We restart the issue and the problem became worse because now the end users have to wait for 5 minutes (300 seconds) before they receive the error message (ORA-02049) and because of that we had to set the value back to 60 seconds.

After that we tried to trace the error using different event trace levels but with no luck we were not able to determine what is causing the error.

We thought that it’s a database bug and oracle advised us to upgrade the database from 9.2.0.5 to 9.2.0.7 we did that but still the issue is there.

After a month of investigation/tracing and snapshot of when the problem is happing we managed to find out what was causing the problem. It was a bitmap index that was built on the table we were trying to insert data on.

When an end user was trying to sale without committing his transaction for some reason and at the same time another end user tries to sale he will receive the error message and a lock on the table happened and the error pops-up.

We solved the issue by dropping the bitmap index and creating a normal b-tree index even though the column has only three distinct values.
