      - What is the CICS® VR change accumulation utility?
        CICS® VR change accumulation (CA) is the process of consolidating forward recovery log records into a change accumulation data set. CICS VR uses the change accumulation data set in conjunction with the forward recovery log to speed up forward recovery processing.
      - What is the CICS® VR RCDS export/import utility?
        You can use the CICS® VR RCDS export/import utility to extract the information in your RCDS so that you can send it to your remote recovery site and incorporate the information into its RCDS.
      - What is VSAMREC?
        VSAMREC is the name of a list command and line operator that can be issued from the ISMF data set list. Use the ISMF data set list feature to group VSAM spheres based on user-defined selection criteria.
    - CICS® VR functions for CICS® TS
      The CICS® VR functions that are specifically available in the CICS TS environment.
    - Batch functions
      The batch functions that can be used with CICS® VR.
  - CICS® VR capabilities and limitations
    Descriptions of the capabilities and limitations of CICS® VR.
- Overview of CICS VR installation
  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.
- Migration considerations
  Consider these general migration considerations when you migrate to CICS® VR 6.3 from an earlier release.
- Activating the CICS® VR server address space
  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.
- Setting up CICS® VR VSAM batch logging
  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.
- CICS® VR security
  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 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 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.

What is the CICS® VR server address space?

The CICS® VR server address space is an essential part of CICS® VR. It is started when MVS™ is IPLed.

The CICS® VR server address space must be active if you want to use any of the following CICS® VR functions:

CICS® VR VSAM batch logging.
Notification and registration of logical backups in the CICS® VR RCDS.
Notification of CICS® backout failures in the CICS® VR RCDS.
Automated change accumulation processing with backups of which CICS® VR is notified.

The DISPLAY and VARY commands are available to display and alter the status of the CICS® VR server address space.
