On right side will see  Configuration > "Customize this table"

 




   Click  >     oacore_server1

   Click  Server Start ("Sub Tab")

   Click Lock & Edit

   Go to Arguments

 

  Entry like this.

  -Xms512m -Xmx1024m -Djava.security.policy=/../fs1/FMW_Home/wlserver_10.3/server/lib/weblogic.policy

 

  Change to

 

  -Xms1024m -Xmx2048m -Djava.security.policy=/.../fs1/FMW_Home/wlserver_10.3/server/lib/weblogic.policy

Click the 'Save' button to save the configuration changes.

Specially during Downtime autoconfig can also be modified


s_oacore_jvm_start_options in the $CONTEXT_FILE and re-run autoconfig

There isn't a necessity to make any changes in the Patch FS.

When changes done in Run FS and start the adop patch cycle by running adop phase=prepare, the CCD (Configuration Change Detector) will be invoked and

it will compare the configuration files and will take care of implementing the necessary changes.

Linux OL7/RHEL7: PRVE-0421 : No entry exists in /etc/fstab for mounting /dev/shm

  This is due to below bugs: OL7 -  Unpublished Bug 21441387- 12.2/MAIN/OL7.1: CVU REPORTS /DEV/SHM NOT MOUNTED WHEN IT IS MOUNTED  21441387.8 RHEL 7 - Unpublished Bug 25907259 : RHEL7.2: CVU REPORTS /DEV/SHM NOT MOUNTED WHEN IT IS MOUNTED  25907259.8 As a work-around in OL7: In OL7, the /dev/shm is not mounted in /etc/fstab on a fresh system, it is done in: [root@testc140 u02]# ll /usr/lib/dracut/modules.d/99base/init.sh -rwxr-xr-x. 1 root root 11379 Mar 26 10:14 vi /usr/lib/dracut/modules.d/99base/init.sh and comment the below lines 62 if ! ismounted /dev/shm; then 63 mkdir -m 0755 /dev/shm 64 mount -t tmpfs -o mode=1777,nosuid,nodev,strictatime tmpfs /dev/shm >/dev/null 65 fi so, this validation is not really valid for OL7.    We can also safely ignore this message.

How to troubleshoot Long Running Concurrent Request in EBS 12.2

 The following points need to answer before jumping into troubleshooting: Are there any recent code changes done in the concurrent program?           Check long_running_sid and verify the recent code change of last_ddl_timestamp after a             discussion with the developer. Was this running long in the last few run as well, or was this time only?            ==> Check the program history. How much time does it take to complete?           Once again program history can give us some idea. Are these jobs fetching higher data compared to the last run           ===> Confirm on data change . Query Plan change will indicate this issue. Does this job runs at any specific time or it can be run anytime           ===> The nature of the job can help to understand the job's nature. Does this job fetch data using DB Link...

How to write to a CSV file using Oracle SQL*Plus

  SPOOL command  The  SPOOL  command is  unavailable  in the browser-based SQL*Plus version,  iSQL*Plus . To generate files while using iSQL*Plus, change the necessary preference settings to directly output to a file. This is accomplished using the  SPOOL  statement. While  SPOOL  is  active , SQL*PLus will store the output of any query to the specified file. Therefore, the next command to enter is  spool : spool filepath Skipping ahead slightly,  after  your query is inserted, you also need to halt  spool  so the file output is closed by using the  spool off  command: spool off Insert the query  The last step after the settings are modified and  spool  is running is to insert your query. For our simple example, we’re outputting all books from our  books  table. SELECT   title,   author FROM   authors; Don’t forget the semi...
