CICS® VSAM Recovery Version 6 Release 3 (CICS VR) recovers your lost or damaged VSAM data.
CICS® VR offers many different functions. Some functions are specific to a particular environment such as: VSAM batch logging, or CICS TS.
The batch functions that can be used with CICS® VR.
CICS® VR 6.3 contains these changes.
CICS® VR uses logs to recover your VSAM data.
CICS® VR helps you recover your VSAM data sets in CICS VR VSAM batch logging, when the VSAM data sets are not accessed in record level sharing–mode following, and CICS TS environments.
The functions that can be used with CICS® TS, or without CICS.
The CICS® VR functions that are specifically available in the CICS TS environment.
CICS® VR VSAM batch logging provides logging for your batch changes to VSAM data sets that are not accessed in RLS-mode.
CICS® VR batch backout allows you to remove updates that were made to VSAM data sets by a failed batch job step.
Descriptions of the capabilities and limitations of CICS® VR.
This information describes all the necessary steps to successfully set up CICS VR 6.3. It includes a detailed description of the various CICS VR components and how to set them up. The CICS VR server address space is required for batch logging, backup notification, and backout failure notification.
Consider these general migration considerations when you migrate to CICS® VR 6.3 from an earlier release.
The CICS® VR server address space provides a communication vehicle for CICS VR and other applications. It must be active if you want to use any of these CICS VR functions.
CICS® VR VSAM batch logging, referred to as batch logging, provides logging of updates made to VSAM data sets by batch jobs. Two types of batch logging are available, forward recovery logging and undo logging.
Security has been enhanced to protect the RCDS from being updated by any user. It is possible to specify that the users security profile must be checked before allowing certain information in the RCDS to be added, changed, or deleted.
CICS® VR forward recovery consists of a restore and then forward recovery.
The information in the following topics describe how to take a backup using CICS® VR. The panels and secondary windows are in the sequence that they are displayed during a backup job generation.
You can reorganize a VSAM sphere using CICS® VR. VSAM sphere reorganization can increase the space of a sphere and its alternate indexes. It can also change the control interval sizes for a sphere's components.
The CICS® VR recovery and backup functions are typically accessed using the Utilities pull-down menu after selecting VSAM spheres.
The CICS® Backout Failed sphere list shows the CICS spheres registered for manual recovery or reorganization after CICS notification of a backout failure.
CICS® VR is integrated with ISMF so that you can create a CICS VR recovery job for the data sets in an ISMF data set list by entering the VSAMREC line operator or list command. When you enter the VSAMREC line operator or list command, the necessary CICS VR panels are called and you can create a recovery job for the VSAM sphere.
IBM® recommends that you use the CICS® VR panel interface to create recovery jobs for your VSAM spheres. Using the CICS VR panel interface eliminates the need for you to manually keep track of daily update activity, logs, backups, etc. Also, the CICS VR panel interface automatically creates the recovery JCL for you.
The CICS® VR batch backout utility allows you to remove updates that were made to KSDS, ESDS, RRDS, and VRRDS VSAM spheres by steps in a batch job. This section describes how to run the CICS VR batch backout utility.
The CICS® VR forward recovery and batch backout utilities produce a set of reports upon successful completion. The reports are written to the data set allocated to the DWWPRINT ddname. However, the set of reports written for the forward recovery backout utilities differ from the set of reports written for the batch backout utilities.
The IBM® Customer Engineering Program Support structure helps you resolve problems with IBM products, and ensures that you can make the best use of your IBM computing systems.
If you have to contact IBM® personnel about a CICS® VR problem, you must classify and describe the problem.
You can determine the cause of a CICS® VR abend in a number of ways.
The reference sections of the information contain reference information that you need when you use CICS® VR.
