Issue:
I was trying to add a node in RAC environment using the below command; the prerequisites were all met and the copy portion of files was in progress. But, after some time, noticed that files were not being copied over to the other node. Noticed a “.err” file in oraInventory/logs with the below error message.
Command Executed:
./addnode.sh -silent “CLUSTER_NEW_NODES={node2}” “CLUSTER_NEW_VIRTUAL_HOSTNAMES={node2-vip}”
Error in the logfile:
Exception in thread “AddNode API Thread” java.lang.OutOfMemoryError: Java heap space
Cause:
The Copy process is using a java process which might be consuming all the memory
Resolution:
There are two possible solutions for addressing this issue,
1. Increase memory settings in oraParams.ini files
Navigate to $ORACLE_HOME/oui/ and modify the JRE_MEMORY_OPTIONS in oraparam.ini to a higher valuer (depending on the free memory on the server)
Eg: JRE_MEMORY_OPTIONS=” -Xms1500m -Xmx1500m -XX:MaxPermSize=128M”
Once the above change is done, restart the ./addnode.sh command
2. The main culprit for this process to error out could be “Audit Files” in “$ORACLE_GRID_HOME/rdbms/audit”
you could purge the files and retry the command
