Oracle Grid Infrastructure 11g Release 2 is a packaged software installation type that integrates ASM, ASM Cluster File System, Oracle Database, and Oracle Restart. It is designed to push the deployment of the different components of a highly available database into two different operating system accounts—ASM+ CFS and RDBMS. At the same time this allows multiple people to administer their respective components—the system administrator configures hardware and storage, the network administrator configures all network components, and the DBA is in charge of the database.
SYSASM
and SYSDBA
are privileged accounts associated with an ORACLE_HOME
. The SYSASM
account has privileges (for performing specific tasks) granted to an ASM ORACLE_HOME
with a SYSDBA
account with privileges to a Database ORACLE_HOME
. Currently, both ORACLE_HOME
types (ASM and Database) can exist in the same ORACLE_HOME
installation directory.
