CA View provides optional drivers that enable you to archive SYSOUT data to the following:
  • FileTek Optical Disk Storage Machine
  • Kodak Optistar Storage System
  • IBM 3995 Optical Library Dataserver, models 131, 132, 133, and 153
Using the CA View optical disk driver also enables you to retrieve data from an optical disk to the CA View database to view or print. After you configure CA View to use an optical disk driver, CA View archives SYSOUT data to three levels of storage:
  • Primary disk
     
    (the CA View database)
  • Secondary disk (optical disk; saved using the driver)
  • Tape storage (CA View archival tapes)
Note:
In this document, the terms
secondary storage
and
optical disk storage
are used interchangeably.

What Is Secondary Disk Storage?
Secondary disk storage
 is a storage alternative to the CA View primary disk database. You can specify an optical disk device as a destination for SYSOUT archiving to create a more portable and permanent backup for reports.
When to Use Secondary Disk Storage
Select a destination for SYSOUT group archiving based upon retrieval frequency and retention period.
  • Use primary disk storage to store:
    • SYSOUT groups that you must view frequently because the SYSOUT group is always available for immediate retrieval.
    • Any SYSOUT group with a relatively short retention requirement because primary disk space is reusable and the space quickly becomes available again.
  • Use secondary disk storage (optical disk) to archive:
    • Any SYSOUT group with a relatively long retention period
    • Any SYSOUT that is frequently required for viewing.
    When an optical disk is used for this kind of storage, it is an extremely reliable and cost effective medium.
  • Use tape storage to back up SYSOUT groups on primary or secondary disk.
Requirements
The system requirements for the CA View Optical Disk Interface are as follows:
  • To use any of the optical disk interfaces you must have CA View r11 (or higher) and the CA View Expanded Retention Option (ERO).
  • The Kodak Optistar Storage System page level driver requires the Data/Ware Multi-user Data Retrieval Subsystem (MDRS).
  • The FileTek drivers require the FileTek callable interface (module LSMCALL).
  • The OAM driver needs OAM to be is running with all CA View transactions occurring on the system that is running OAM. This involves the following:
    • The CA View archival started task must execute on the system with OAM if either the CA View backup cycle or optical migration subtask does the migration to OAM.
    • All online users selecting SYSOUT groups from secondary disk storage must be executing on the system with OAM.
    • Users on another system can load the SYSOUT group from secondary disk to the CA View database in order to access it. The SARBCH job used to load the SYSOUT group must run on the system with OAM.
    • All SARBCH jobs requesting SYSOUT groups from secondary disk storage must execute on the system with OAM.
Report-Level versus Page-Level Access
When you select a SYSOUT group from CA View that has a status of DSK2, PDK2, or PRM2, CA View does one of the following:
  • Allows you to view or print the SYSOUT file directly from optical disk (page-level access)
  • Loads the entire SYSOUT from the optical disk into the CA View database (report-level access)
Notes:
  • DSK2, PDK2, or PRM2 all indicate optical disk secondary storage.
  • Most of the information in this document applies to both types of drivers.
Driver Names and Types
CA View currently supports the following optical disk drivers:
  • SARD2D00 for IBM DASD Emulation Optical devices (including the ESA/370 and ESA/390 3995 model 153 Optical Library Dataserver) with page-level access
  • SARD2D01 for the Kodak Optistar Storage System with report-level access
  • SARD2D02 for the FileTek Optical Disk Storage Machine with report-level access
  • SARD2D03 for the FileTek Optical Disk Storage Machine with page-level access
  • SARD2D04 for the Kodak Optistar Storage System optical disk device with page-level access
  • SARD2D05 for IBM Object Access Method (OAM) devices (including the ESA/370 and ESA/390 3995 models 131, 132, and 133 Optical Library Dataserver) with page-level access
