RAC instance stucking in open phase

in Database ORA-600 / ORA-7445 Analysis , Diagnostic Repository (ADR) & Packaging (MOSC) 1 commentAnswered

Dear Community,

I need to find out what're libraries being called during an open phase of a stuck-in-the-open-phase instance, to see what the instance is looking for while it's hanging/and what library or maybe oracle function, it's been called up. I've already tried hanganalyze without any clue within the trace to drive to the RCA. I guess the last resource would be any event with any short stack, or maybe ltrace, but I'm not sure which one suit best.  

DB 18.14 Oracle Linux 7.9

I would appreciate input from the community.


Thanks in advance.

Howdy, Stranger!
