Cloning an Existing Oracle11g Release 2 (11.2.0.x) RDBMS Installation
Cloning an Existing Oracle11g Release 2 (11.2.0.x) RDBMS Installation: Step 1: Make a copy of the existing (source) Oracle RDBMS installation. If the clone (target) installation is on the same server then the " cp -Rp " command could be used. NOTE: There should be no requirement to shutdown any databases, listeners, agents etc. that are running from the source home before copying the source installation because any processes that load the static binaries or libraries into memory should not hold a write lock. For example: cp -Rp /u01/app/oracle/product/11.2.0 /u01/app/oracle/product/11.2.0_clone NOTE: This command can be executed by either the ' root ' user or the owner of the $ORACLE_HOME (F or example , ' oracle '). The intention is to make sure that the ownership of the files is preserved correctly. Some files in $ORACLE_HOME/bin are owned by root and have the SUID / SGID set: -rws--x--- 1 root oinstall 20872 Apr 24 12:00 nmb -rws
