ORA-29702: ERROR OCCURRED IN CLUSTER GROUP                                            SERVICE OPERATION

While starting the RAC instance , after changing the hostname in cluster nodes.


ora-29702 error occurred in cluster group service operation startup

SQL> startup nomount;
ORA-29702: error occurred in Cluster Group Service operation

Findings :

1) As it is cluster nodes database , cross-checked the cluster parameters like cluster_interconnect,no of threads,cluster_dataabase etc.
2) Cross-checked the all cluster nodes are pinned to the cluster group.


Here one node has not been pinned to the cluster group .

[oracle@ordbtest2 bin]$ ./olsnodes -s -t

ordbtest1        Active  unpinned
ordbtest2        Active  pinned
ordbtest3        Active  pinned

So we have to pin the node from the available nodes either ordbtst2 or ordbtest3.

[root@ordbtest2 bin]# ./crsctl pin css -n ordbtest1
CRS-4664: Node ordbtest1 successfully pinned.

And now startup the database , it will start without any error.
