Hi all experts,
Good morning. We are on WIN 2012R2 , DB & RAC 12.1.0.2 with ASM. Our cluster is pretty stable . However, last night first node rebooted with following messages.
ASM log
Fatal NI connect error 12638, connecting to:
(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
VERSION INFORMATION:
TNS for 64-bit Windows: Version 12.1.0.2.0 - Production
Oracle Bequeath NT Protocol Adapter for 64-bit Windows: Version 12.1.0.2.0 - Production
Time: 23-OCT-2017 22:05:11
Tracing not turned on.
Tns error struct:
ns main err code: 12638
TNS-12638: Credential retrieval failed
ns secondary err code: 0
nt main err code: 0
nt secondary err code: 0
nt OS err code: 0
Then i had to restart HAS manually and i see CRSD did not come by itseld due to this,
[OHASD(4504)]CRS-8503: Oracle Clusterware OHASD process with operating system process ID 4120 experienced fatal signal or exception code -529697949
I would appreciate if you guys points me how i can trouble shoot this. Especially ASM logs errors. Thanks.
