How to fix DATAGUARD UNRESOLVEABLE GAP on ASM

edited Jul 2, 2014 10:45AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 7 commentsAnswered ✓

I am running datguard on ASM on Oracle 11g 11.2.0.3, about a month ago we have encountered a crash because the flashback area was full. I wasn't able to bring up the DB or connect to the DB using RMAN. I finally manage to connect to the ASMCMD and deleted the older logs and managed to restart the DB. Now my RMAN delete expired fails giving me warning that the logs that I am trying to delete aren't applied to the STDBY. Upon further investigation I have determined that there is unrecoverable gap in the logs.

Please let me know if anyone had the similar issue and what is the resolution.

Howdy, Stranger!
