Welcome
Running CICS® VR batch backout
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.
Starting CICS® VR batch backout
CICS® VR batch backout processing is started by running the DWWBACK program.

What's new in CICS VR 6.3
CICS® VR 6.3 contains these changes.
Operating environment
CICS® VR uses logs to recover your VSAM data.
CICS VR Overview
Getting Started
CICS® VR and CICS® TS
CICS VR Exits
Running CICS® VR forward recovery
CICS® VR forward recovery consists of a restore and then forward recovery.
Running CICS® VR backup
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.
Running CICS® VR reorganization
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.
Working with other VSAM sphere list pull-down menus
The CICS® VR recovery and backup functions are typically accessed using the Utilities pull-down menu after selecting VSAM spheres.
Working with CICS® Backout Failed spheres
The CICS® Backout Failed sphere list shows the CICS spheres registered for manual recovery or reorganization after CICS notification of a backout failure.
Working with logs
Using ISMF data set lists with CICS® VR
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.
Running CICS® VR manually
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.
Running CICS® VR batch backout
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.
- Understanding the common batch window problem
  In many environments, the batch window is a predefined time of day that VSAM spheres can be offline, unavailable for online CICS® processing.
- Starting CICS® VR batch backout
  CICS® VR batch backout processing is started by running the DWWBACK program.
  - Automatically running CICS® VR batch backout
    CICS® VR can be configured to automatically start the batch backout utility when a batch job step encounters an abend.
- Executing batch backout when the RCDSs are unavailable
  In most scenarios, the RCDSs that were allocated to the CICS® VR server address space when the batch job that made the updates you want to back out was originally run are allocated to the CICS VR batch backout job on the DWWCONx DD statements. However, you might encounter a situation where the RCDSs are no longer available.
- Additional ESDS considerations
  When a record is added to a VSAM ESDS by a batch job, CICS® VR undo logging writes a before-image log record with the RBA of the record that was added to the undo log stream. Therefore, during batch backout processing, CICS VR locates any records that were added to the ESDS by the batch job step.
- Understanding CICS® VR batch backout completion
  Upon completion of the CICS® VR batch backout program, messages are written to the data set allocated to the DWWMSG ddname indicating the result of the processing.
Understanding CICS® VR reports
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.
Understanding IBM® program support
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.
Problem determination procedures
If you have to contact IBM® personnel about a CICS® VR problem, you must classify and describe the problem.
Diagnosing the causes of abends
You can determine the cause of a CICS® VR abend in a number of ways.
Reference information
The reference sections of the information contain reference information that you need when you use CICS® VR.
Glossary
The terms in this glossary are defined as they pertain to the CICS VSAM Recovery documentation.
Edition notice
This is the information for CICS VSAM Recovery for z/OS. It applies to CICS VSAM Recovery for z/OS Version 6.3, and to all subsequent versions, releases, and modifications until otherwise indicated in new editions. Make sure you are using the correct edition for the level of the product.

Starting CICS® VR batch backout

CICS® VR batch backout processing is started by running the DWWBACK program.

The DWWBACK batch backout program can be started in one of the following ways:

Automatically by CICS® VR when a batch job encounters an abend.
Manually by creating and submitting a batch job that starts the DWWBACK program.

Note:

To use the CICS® VR batch backout utility, undo logging must enabled for the VSAM spheres, along with some other additional configuration. See Setting up CICS VR VSAM batch loggingCICS® VR Implementation Guide and Reference, for further information on setting up CICS® VR VSAM batch logging.

CICS® VR batch backout supports KSDS, ESDS, RRDS, and VRRDS VSAM spheres.

The following sections describe the manual and automatic execution of CICS® VR batch backout.
