Description

This bug is only relevant when using Real Application Clusters (RAC)

OHASD may not restart CRSD when crsd.bin is hanging

Rediscovery Notes

1. We may have this scenario:

Time 1. CRSD hangs

Time 2. OHASD is terminated

Time 3. CRSD still hanging

Time 4. OHASD restart

2. A call stack on OHASD reveals a check on ASM is running:

....

#28 0x0000000000a098fb in CLS_Threading::CLSthreadMain::cppStart(void*) ()

3. When the check action on ASM is completed (or aborted) then OHASD tries to start CRSD. This could happen after 20 mins.

Workaround

Start the CRSD resource running:

crsctl start res ora.crsd -init

Note. This fix is dependent on the fix for bug 8934841
