Distributing Data Files Across Disks

If you have multiple physical disks available for your database you can improve performance by distributing data files between disks.

Placing log files on one disk, indexes on another disk, and data tables on a third disk, can reduce I/O contention.

To distribute data files across disks, indicate different disks at installation time, or follow the re-installation procedures.

Note: For more information, see Configure a CSE Server Environment in the CA Gen Client Server Encyclopedia User Guide.

During installation the log files are created in $ORACLE_HOME/dbs. The log file directory, the index tablespace and application table tablespace location are specified during installation.

If you will be performing uploads and checkouts with large models (more than 125,000 objects), your system will require additional virtual memory. Work with your UNIX Administrator to allow for this by setting the kernel configuration parameter maxdsiz.

You also will need to ensure that you have adequate swap space. Use the online help in the CSE Support Client to assist in determining an appropriate amount of swap space for Object Cache settings.
