After applying EBS 12.2.13 RUP on Redhat Linux 8.9 OS, Viewing the Output and Log Files from any Concurrent Request Shows a Blank Page in the Browser

Environment: Oracle EBS Release that is 12.2.13 with 19c that is 19.22 which is Running on Red Hat Enterprise Linux release 8.9 (Ootpa)

Issue:

After Applying :

1. R12.AD.C.delta.15 -> 34695811
2. R12.TXK.C.delta.15 -> 34785677
3. Oracle E-Business Suite 12.2.13 Release Update Pack -> 34776655
   
   We started facing problem i.e Concurrent Request Output and Log output displays Blank Page in the Browser.

SOLUTION:

Make sure to shutdown EBS Services including Weblogic

Then Run the following commands to unzip the container and WLS patch respectively and then Apply below Weblogic Server Patch ( for OL8/RHEL8 customers only ):

1. cd /u01/8005_uat_app/ebiz/fs1/FMW_Home/utils/bsu/cache_dir/

2-a. unzip -o /u01/EBS_UPDATE_12_2_13/CONC_LOG_NO_OUTPUT/p32931976_R12_GENERIC.zip
2-b. unzip -o /u01/EBS_UPDATE_12_2_13/CONC_LOG_NO_OUTPUT/p31090393_1036_Linux-x86-64.zip —-> EG54.jar delivered by this patch is actually going to fix.
