How to drop Old Database edition in R12.2

By -

 Dropping old database editions:

As online patching cycles are completed, the system will build up several old database editions. When the number of old database editions reach about 25, you should consider running a special maintenance operation to drop old database editions.

Use below script to find DB edition details

Cd $AD_TOP/sql/ADZDSHOWED.sql

Output:

SQL> @ADZDSHOWED.sql

=========================================================================

= Editions

=========================================================================

Edition Name Type Status Current?

--------------- -------- -------- -------- ---------

V_20210318_1313 ACTIVE

V_20210323_0209 ACTIVE

V_20210421_0706 ACTIVE

V_20210428_1036 ACTIVE

V_20210505_0620 OLD ACTIVE

V_20210507_2006 RUN ACTIVE CURRENT

Disconnected from Oracle Database 19c EE Extreme Perf Release 19.0.0.0.0 - Production

Actualize_All and Full Cleanup will clear the old database

Example

adop phase=prepare

adop phase=actualize_all

adop phase=finalize

adop phase=cutover

adop phase=cleanup cleanup_mode=full

Note:

This maintenance operation will take much longer than a typical online patching cycle and should only be performed when there is no immediate need to start a new online patching cycle.

We can execute Actualize_All and Full Cleanup combined with part of patching

Example:

adop phase=prepare

adop phase=apply patches=123456,765101,11121314

adop phase=actualize_all

adop phase=finalize

adop phase=cutover

adop phase=cleanup cleanup_mode=full

adop exiting with status = 0 (Success)

How to troubleshoot long running concurrent request in R12.2

By -
Normally we are getting concurrent program running longer and concurrent request not picking jobs, etc. those are very frequent issue we expected from development team. Collect below basis level of information to development team 1 Oracle seeded program/Custom program? 2 How much time it used earlier? 3 Is there any recent code change done in concurrent program? 4 Is this program fetching higher data compare to last run? 5 Does this job running any specific time/ It can be run any time? 6 Does this job fetching data using DB link? 7 Does the problem happen on both the test and production instance? Once asked above questions to development team in meanwhile we need to start basic sanity check in our environment. 1 Verify the status of the concurrent program Copy select REQUEST_ID,phase_code,status_code,ORACLE_SESSION_ID from apps.fnd_concurrent_requests where request_id=’1234567’;
