Hi,

We have Oracle 11.2.0.3 two node RAC which is running in Linux RedHat OS.

CRSD went down in one node due to  routing info missing for which we raised a sev1 SR and Oracle support confirmed that its bug and they initiated for a bug fix patch..

During this incident, we didn't have any issues becuase all the applications was connected to available node as all the instances were up and running on the other node.

The problem is that one of our application user was not able to connect to the database which was running on other node.

When they tried to connect the database from their apps server they got "TNS-12535: TNS:operation timed out" for few hours.

Howdy, Stranger!
