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

Operation

With page-level access, you can add indexes to your SYSOUT archives at archive time. The optical disk interface uses these user-defined indexes to reduce optical disk access time, minimizing 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 indistinguishable from viewing records from primary storage.
