From the above output we see only DEV03 database which is FIRST line in mgr param file

Now, Lets try to Refresh manager using below command and see if it changes……….

Mgr Params Updated

NOTE:   DO NOT Rely on above refresh mgr command as it has only LIMITED purpose and Functionality. so better STOP and START manager but careful this will bring down EXT and REPLICATS running associated with this Manager.

No Changes happened………….From the above output we can see that though I have specified multiple lines in the manager param file for deleting trail files using PURGEOLDEXTARCTS using checkpoints it still takes ONLY the first line in the manager param file and this behavior is concluded as a BUG # 22912874 in 12.2 and the fix is in 12.3 version.

According to the (Doc ID 2149579.1) the Work around is to use the Parent directory instead of multiple directories 

Workaround :

WAIT for around 5 to 10 mins and it will Work as expected for all the directories ...........
