SYS.DBMS_JOB.SUBMIT
*( job => X*
*,what => 'BEGIN INVS_RIM_DATA_LOAD(''01A'',''RIMADMIN'',TRUNC(SYSDATE)); END;'*
*,next_date => to_date('15/08/2011 23:09:00','dd/mm/yyyy hh24:mi:ss')*

For taking the cold backup, db is shut down on every Friday 11:00PM and open by 02:30 PM Saturday. So job expected to run on Friday night will be running by Saturday 02:30AM. It is ok for us. But problem is job is not running on Saturday night.
When checked on Sunday morning the user_jobs shows details as
Last_date : 13-Aug-2011 02:30:14 AM
Next_Date : 14-Aug-2011 11:09:00 PM
Issue we are facing is job is not running on 13-Aug 11:09:00 PM
Please help me to fix this issue.

Well, it runs on the expected time (for me). This is your interval: TRUNC(SYSDATE+1)+23.15/24
If the last job run at 13-Aug-2011 02:30:14 AM, then the next one should be:
= TRUNC( '13-Aug-2011 02:30:14 AM' + 1 ) + 23.15/24
= TRUNC( '14-Aug-2011 02:30:14 AM' ) + 23.15/24
= '14-Aug-2011' + 23.15/24
= '14-Aug-2011 11:09:00 PM'
You can create an additional job which will work at Saturday nights. This is the easiest fix I can think.
