Description
ORA-7445 [kggibr()+52] during RECOVERY when platform is
IBM AIX on POWER Systems (64-bit). This bug is more commonly
seen in RDBMS version 11.2.0.1.

This is a fix to prevent a parallel recovery slave process
from crashing with an ORA-07445 during recovery.

Rediscovery Notes:
Look for all the following:
- a parallel recovery slave crashes with a ORA-07445 with
krp_next_cv_for_apply() on the stack
- for example in 11.2.0.1 on AIX the top of the crashed
process's stack looks like this:
-> krp_next_cv_for_apply() -> kggibr()+52 -> ORA-07445
- the recovery coordinator process (eg MRP on a standby
database) terminates recovery and writes the following
message to its tracefile:
ORA-10878: parallel recovery slave died unexpectedly
This error may also be accompanied by
ORA-16766 Redo Apply is stopped
- the memory model of the underlying platform is non-TSO
(eg AIX.PPC64)

Workaround:
Restart recovery or use serial recovery
eg: ALTER DATABASE RECOVER MANAGED STANDBY
DATABASE USING CURRENT LOGFILE DISCONNECT noparallel;
