Using the Optical Disk Interface › Optical Disk Page-Level Access › Page-Level Access Functionality

Page-Level Access Functionality

This functionality lets you do the following:

• Access archived SYSOUT data directly from optical disk secondary storage

Page-level access is different than report-level access which requires an entire SYSOUT to be loaded into the CA View database for viewing.

This capability helps you reduce the DASD load at your site while minimizing the performance impact of the slightly slower access speed of optical disk. Instead of loading a 100,000-line report back to the CA View database, you can view or print just the data you need.

• Add indexes to your SYSOUT archives at archive time

  The optical disk interface uses the user-defined indexes to reduce optical disk access time. Using indexes minimizes the performance impact of the slightly slower access speed of optical disk.

  The net result is that, depending on your indexing and the number of concurrent access requests to optical disk, the response time can be the same as primary storage.
