Add new node to apps

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

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

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

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

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.

ATG Rollup 4 and my Custom schema

After Appling ATG Rollup 4 patch no. (4676589) on our HP-UX server successfully we start to receive the following error only on our customized schema but not on the standard schemas.
The error was showing when we try to run any procedure from this customized schema we keep getting the following even though it used to work fine before the patch
"
ORA-00942: table or view does not existORA-06512: at "APPS.FND_CORE_LOG", line 23ORA-06512: at "APPS.FND_CORE_LOG", line 158ORA-06512: at "APPS.FND_PROFILE", line 2468ORA-06512: at "APPS.XX_PACKAGE_PA", line 682ORA-06512: at line 4
"

After checking on metalink we got a hint from note 370000.1 the note dose not apply for the same case but it did gave us the hint and the solution was as follow

connect as APPLSYSGRANT SELECT ON FND_PROFILE_OPTIONS TO SUPPORT;GRANT SELECT ON FND_PROFILE_OPTION_VALUES TO SUPPORT;


Support is my customized schema Custom
Have an error free day ;-)

Issues while installing oracle redhat linux

Before a couple of days me and my friend ghassan who is also a certified apps 11i dba was doing an installation at my new p.c and while installing oracle linux on the new Intel 965 motherboard the installer freezes at " PCI: Probing PCI hardware (bus 00)" stage after checking redhat forums we found out that we need to start the installation using the following command from the command line to over come this issue
linux all-generic-ide pci=nommconf
of course that solved our issue after the installation finished and the system reboot we had to do the following the grub screen

at the grub menu. Select the kernel we want to edit, and press (e) to edit. Then move the cursor down to the "kernel" line and press (e) to edit that line. And add the all-generic-ide pci=nommconf at the kernel line.
Then press ENTER to accept the changes. And then press (b) to boot.

When the server boot successfully we had to add the all-generic-ide pci=nommconf at the /boot/grub/grub.conf file.

I guess that this issue in not only related to oracle linux but general to all redhat with this Intel motherboard (from what we saw at the redhat forums), anyway after that we did the installation for vision database and the installation went successfully but with one small issue (RW-50004) at step 2 of 5
At the log it shows (ORA-01031: insufficient privileges) this error was a typo of the oracle user group the group was ordba instated of oradba so we fixed that and the installation went successfully


Hope that helped and thank you guz for your help
Fadi
P.S I got the redhat issue resolved mostly from the http://www.linuxquestions.org/questions/showthread.php?t=479778 and some other forums

Thank you apps community

Today is my first day at work after the EPI-LASIK Surgery and my sight is facing haze, glare, ghosts and halos it will need more time before it become stable, I would like to take the chance to thank all apps community who wished me luck during my eye surgery, special thanks goes to hussine sawwan (hsawwan) for his phone call from Kuwait to check on me, and big thanks goes to Steven Chan for taking time to leave comment wishing me luck during the surgery. I would like also to thank marwan shantir, moh'd abu saif and adam shaug for their concerns. During my off days the most I missed was the oracle forums and the oracle blogs, I will need time to keep up with them.

Multi to Single node Cloning issue

A friend called me yesterday he was facing the following error when he tried to clone from multi node to single node cloning
"Could not create the high water mark manifest..Please re-run the program to create the manifest required for merging APPL_TOPs"

He faced this error after he run the (perl adpreclone.pl appsTier merge) and then he cancel it while running and then he run it again on the other node then he recived this error.

According to metalink notes 372819.1 and 372758.1 he should reapply the AD.I.x patch again to the node and then run Maintain snapshot and then run the perl adpreclone.pl appsTier merge again, we did so and every thing went fine.

Hope that helped and by the way this will be my last post before my Eye LASIK Surgery which is scheduled tomorrow morning at 8:30 a.m.

Support forum,

I am thinking of opening a forum here to share support cases with all users, even though I guess oracle forums a great place to post problems and to get answers quickly, I will try to open my own forum for 3 months period if it was successful I will keep it other wise I will stick with oracle forums.
Suggestion are welcomed

Oracle support day in amman

Been busy lately, yesterday I went to oracle support day at Hayyat Amman. It was presented by two oracle support managers, wael sadaqa from Oracle dubi and jafar al omary from Oracle Saudi Arabia, they presented how to work effectively with support and the escalation process and they also stressed on using oracle diagnostics and configuration support manager. They mentioned a little bit about R12 upgrade process and they mentioned that people who are doing upgrade will get more attention from oracle support.
It was good and helpful, the presentations can be downloaded from here

Open Workflow notifications list is very slow

Here I am publishing a note which I already published on metlaink through the Customer Knowledge Exchange program the note id is 428573.1, they had this program a couple of months ago and I managed to publish two notes and I will be sharing them here with you.

I faced a slow performance issue which only applies on the notifications list page, opening the workflow notifications list to see a list with two notifications when the problem happened used to take a lot of time (more that 20 minutes and most of the times it used to time out) so I followed the below to solve the issue

SQL> select message_type,count(*) from WF_NOTIFICATIONS group by message_type;

MESSAGE_ COUNT(*)
-------- ----------
AZNM000 3
FERASWF 8
POAPPRV 121
POERROR 29
PORCPT 38
POSDSALE 332
REQAPPRV 131
WFERROR 1137436

8 rows selected.
SQL> select count(*) from WF_NOTIFICATIONS where status='OPEN'
and MESSAGE_TYPE='WFERROR'

998976 rows selected.

I find out that I have a lot of the WFERROR message_type and most of them with an open status so I took a backup of the table just incase any thing went wrong using the following statement

SQL> CREATE TABLE WF_NOTIFICATIONS_bck AS SELECT * from WF_NOTIFICATIONS;

Table created.

Then I run the following update statement to set the status of all open notifications of the WFERROR type

SQL> update wf_notifications
set status='CLOSED', mail_status='CANCELED', end_date=sysdate
where status='OPEN'
and MESSAGE_TYPE='WFERROR' ;

998976 rows created
SQL> commit;

After that I tried the notifications list page it did not take more than 3 seconds and every thing went back to normal, so I scheduled a database job that run every month to close all the open notifications with message_type wferror.

To avoid this problem from happing again I am make sure that all the sysadmin notifications are closed and I also have monthly task to check that the above job is running.

i hope that helped
