DB version: 11.2
In solaris the default location of inventory pointer file is /var/opt/oracle/oraInst.loc
In AIX, Linux the default location of inventory pointer file is /etc/oraInst.loc
In my current shop, most of the DB servers have multiple RDBMS_HOMEs. Here oraInst.loc is stored in $ORACLE_HOME as
$ORACLE_HOME/oraInst.loc
for each RDBMS_HOME. Is this a good practice ?
