Aha....it would appear we are having network issues and connections are being dropped.

Just set up an 11gR2 DG config (one primary/one standby) on Linux and am seeing some strange errors in the standby alert log.....
Every now and again, (its fairly random) the following is happening.
RFS: Selected log 5 for thread 1 sequence 29031 dbid 874073702 branch 764422822

Fetching gap sequence in thread 1, gap sequence 29030-29030

RFS: Selected log 5 for thread 1 sequence 29033 dbid 874073702 branch 764422822

FAL[client]: Failed to request gap sequence
GAP - thread 1 sequence 29030-29030
DBID 874073702 branch 764422822
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
I have googled until I am sick and also been on My Oracle Support . Everything points to a bug (which says has been fixed in 11g) as I have tried all the various select statements from the internal views that have been recommended on various web sites (and MOS) yet they all return no rows which supposedly means all is fine. Despite this we are still missing logs which have not been shipped onto the standby from the Primary.
Any ideas ?
