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.

3. Open  setDomainEnv.sh file that is under the $DOMAIN_HOME/bin directory.

4. Copy and paste the below lines in the setDomainEnv.sh file.

#In case of Admin Server

if [ "${SERVER_NAME}" == "AdminServer" ] ; then

USER_MEM_ARGS="-Xms1024m -Xmx1024m -XX:MaxPermSize=512m"

export USER_MEM_ARGS

fi

#In case of osb_server1 Server

if [ "${SERVER_NAME}" == "osb_server1" ] ; then

USER_MEM_ARGS="-Xms512m -Xmx4096m -XX:MaxPermSize=4096m"

export USER_MEM_ARGS

fi

Xms: The minimum heapsize

Xmx: The maximum heapsize
