Have available your Oracle installation documentation. Refer to those procedures to perform the following tasks.
On phys-sun, prepare the database configuration files.
Place all of the database-related files (data files, redo log files, and control files) on the /oradata/10gR2 directory.
Within the init$ORACLE_SID.ora file or the config$ORACLE_SID.ora file, modify the assignments for control_files and background_dump_dest to specify the location of the control files.
Start the creation of the database by using a utility from the following list:
The Oracle Database Configuration Assistant (DBCA)
The Oracle sqlplus(1M) command
During creation, ensure that all of the database-related files are placed in the /oradata/10gR2 directory.
Verify that the file names of your control files match the file names in your configuration files.
Run the catalog scripts that create the v$sysstat view. The Sun Cluster HA for Oracle fault monitor uses this view.
