ADDRESS OPSCTL Commands for OPSLOG

ADDRESS OPSCTL OPSLOG commands enable you to manage and control the OPSLOGs for use by your CA OPS/MVS subsystem. Each copy of CA OPS/MVS that is active on your system will use a unique set of OPSLOGs.

You may use the following types of OPSLOGs:

• DIV-backed OPSLOG data sets - the data is backed to disk and retained across product restarts.
• In-storage OPSLOGs - not backed to disk - the data is discarded when the log is inactivated or the product terminates.

Each OPSLOG can have the following formats:

• Read/write

  These OPSLOGs are eligible to be the live OPSLOG.

• Read-only

  These OPSLOGs contain restored data from the OPSLOG archival system.

Note: A live OPSLOG is the log currently being updated with new events as they occur in the system.

Warnings:

• DIV-backed OPSLOGs that are used as the live OPSLOG must be treated like a page data set.
• Do not use large in-storage OPSLOGs unless you are certain that your page data sets can handle the potential increased paging load.
• When introducing multiple OPSLOGs into your existing CA OPS/MVS configuration for the first time, and have the OPSLOG archive component previously implemented, you must ensure that CA OPS/MVS r11.6 (or higher) archive components are being utilized.

  Note: For information about migration, see the Release Notes.

Each copy of CA OPS/MVS that is active on your system must use unique OPSLOG data sets if DIV-backed OPSLOGs are being used. Even if you are able to do so, it is unsafe and unreliable to have an OPSLOG DIV data set being used as the live OPSLOG on more than one CA OPS/MVS subsystem.
