Grid Infra $ORACLE_HOME/log maintenance
We have several Oracle 11gR2 Rac cluster nodes and noticed that the Grid Infra (Clusterware/ASM) $ORACLE_HOME/log directory seems to take up about 2.5 to 3.6 GB of space:
/opt/pkg/grid/product/11.2.0/grid/log
For maintenance purposes we'd like to purge files from the $ORACLE_HOME/log location on a regular basis such as files older than 30 days but even though it is a log directory we're not sure if its safe to simply purge all files older than 30 days from this directory location and this is a Grid Infra $ORACLE_HOME and not the Rdbms $ORACLE_HOME with which we are more familiar. Can we delete any files from this directory path location and not affect the running processes (Clusterware/ASM) that run out of this $ORACLE_HOME? Is there some other known method to handle
