ORA-16434: Archive log for branch string thread string sequence string cannot be queued. Cause: An archive log neededby the standby database to resolve a redo gap was
not found on the primary database. This is a fatal situation during aswitchover
because the primary database waits for the target standby to be clear of allarchive
log gaps before allowing the switchover to proceed. If a redo gap cannot be
resolved, the switchover cannot succeed. Action: If the specified logis listed in V$ARCHIVED_LOG for the DEST_ID of the
local destination on the primary database but no longer exists in that locationon
disk, the archived log can be copied back to that location to allow gapprocessing
to automatically resolve the gap. If the specified log has been purged from
V$ARCHIVED_LOG, the archived log can be copied to disk on either the primary
or standby database and registered using the ALTER DATABASE REGISTER OR
REPLACE LOGFILE command.
