Workaround for Growing in Huge Size File crfclust.bdb

Issue : 

File crfclust.bdb is growing in huge size due to an Oracle bug.

[root@db1 db1]# ls -lhrt crfclust.bdb

-rw-r----- 1 root root 42G Sep 7 10:17 crfclust.bdb

Workaround : 

Modify BDBSIZE parameter in config file crf<hostname>.ora to adequately lower value. 

1. Issue "$GI_HOME/bin/crsctl stop res ora.crf -init " on all the nodes of the cluster.

2. Locate the config file $GRID_HOME/crf/admin/crf<hostname>.ora

3. Manually edit the crf<hostname>.ora file on every node of the cluster and

change BDBSIZE tag entry and remove the value (set it to blank) or set it to a lower value.

4. Restart ora.crf daemon on every node.
