Hi,
I am having below error on my standby DB. its started suddenly , now there is as huge gap between my primary archive and standby by archive.
Can anyone help , my DB is on 2 node RAC and my db version is Oracle 12c
have already increase the value of CONTROL_FILE_RECORD_KEEP_TIME but its doesn't work for me.
ERROR :
FAL[client]: Failed to request gap sequence
GAP - thread 2 sequence 4469-4470
DBID 3882014422 branch 882017560
FAL[client]: All defined FAL servers have been attempted.
------------------------------------------------------------
Check that the CONTROL_FILE_RECORD_KEEP_TIME initialization
parameter is defined to a value that's sufficiently large
enough to maintain adequate log switch information to resolve
archivelog gaps.
