This is one of my fist posts under Pythian’s blog. I will try to keep those short and simple at the beginning.
Recently I was troubleshooting a new GNS (Grid Name Services) functionality.
For more information please see here: Oracle Clusterware Network Configuration Concepts.
I have noticed that there is a-trace-level parameter in the GNS process string.
# ps -ef | grep gns
root 26790 1 2 14:41 ? 00:00:00 /u01/app/11.2.0/grid/bin/gnsd.bin -trace-level 0 -ip-address 10.10.193.201 -startup-endpoint ipc://GNS_hostrac01_23867_408c49e351f1f6a8
root 26825 17210 0 14:41 pts/1 00:00:00 grep gns
Unfortunately there is no description as of now in the documentation or MOS on how to change it to generate invaluable diagnostic information.
NOTE: I am sure the documentation will be updated in Database 12c version (c for Cloud ;)
For a time being the following should work for you:
# /u01/app/11.2.0/grid/bin/crsctl modify resource ora.gns -attr "TRACE_LEVEL=6"
# /u01/app/11.2.0/grid/bin/srvctl stop gns
# /u01/app/11.2.0/grid/bin/srvctl start gns
I hope that this advice will help you to diagnose your GNS issue.
I will blog about the way I resolved future GNS-related issues later on.
It looks like I have said too much for my very first post already.
See you around,
