CRS and ORACLE_BASE
37801May 24 2007 — edited May 25 2007In some of the documentation from Oracle, it says not to use the same ORACLE_BASE for CRS and the databases. Then the examples in the oracle manuals and in the books (including Murali Vallath's Oracle10g RAC book, page 207) show the same ORACLE_BASE for the CRS, ASM and databases.
There is one note in the "Oracle Clusterware and Oracle RAC Installation Guide" that says "Because you must change the permissions of all the parent directories of the Oracle Clusterware home directory after installing the software to grant write access only to the root user, the Oracle Clusterware home directory must not be a subdirectory of the Oracle base directory". This seems to indicate it must be a different ORACLE_BASE as well as a different ORACLE_HOME for CRS.
Can anyone tell me if they have encountered issues with having the same ORACLE_BASE for CRS, ASM and the RAC databases if they have different ORACLE_HOME for each?
