ORA-12543: TNS:destination host unreachable When 'crsctl stop crs'

edited Apr 7, 2015 10:05AM in Database - RAC/Scalability (MOSC) 2 commentsAnswered

I have an 11.2 2-node rac cluster with 3 scan listeners. When I shutdown CRS on node 1 using 'crsctl stop cs', clients experienced 'ORA-12543: TNS:destination host unreachable' for few seconds, they issue resolved automatically. I did not expect this behavior as all future requests should simply be forwarded to one of the 2 remaining scan vips.

Would it be possible that a client request resolved to a scan vip as it was in 'transit', and thus, unavailable yet?

Ideas?

Thank you.

Howdy, Stranger!
