CICS VR Overview
Getting Started
- Introducing CICS® VR
  CICS® VSAM Recovery Version 6 Release 1 (CICS VR) recovers your lost or damaged VSAM data.
- Overview of CICS VR installation
  This information describes all the necessary steps to successfully set up CICS VR 6.1. 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 V6.1 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.
  - Understanding the CICS® VR server address space requirements
    To enable the CICS® VR server address space, these are the requirements that must be met.
  - Setting up PARMLIB for the CICS® VR server address space
    Prior to activating the CICS® VR server address space there are parameters that you must specify.
  - Allocating data sets required by the CICS® VR server address space
    During activation of the CICS® VR server address space, CICS VR attempts to allocate data sets to various ddnames. For some of the ddnames, CICS VR attempts to dynamically create, catalog and allocate a data set if one was not created prior to activation.
  - Identifying preallocation errors
    The message that the CICS® VR server address space issues if the DWWMSGx or DWWCONn data sets are not preallocated correctly.
  - Using the DISPLAY command
    You can use the DISPLAY command to display the status of the CICS® VR server address space, logstreams, and RCDS on a single system or all systems that belong to the same CICS VR XCF group.
  - Using the VARY command to activate or terminate the CICS® VR server
    You can use the VARY command to activate or terminate the CICS® VR server on a single system.
    - Activate the CICS® VR server
      If the CICS® VR server fails, it restarts automatically, up to a maximum of six times. If this limit is exceeded, the automatic restart mechanism is disabled and CICS VR terminates. You can restart the CICS VR server.
    - Stop the CICS® VR server
      If you need to stop the CICS® VR server address space, use the VARY SMS,CICSVR,TERMINATESERVER command.
  - Assigning CICS® VR access authority
    By default, all processes started by the CICS® VR server address space run under an undefined RACF® user ID.
  - Authorizing user IDS to issue DFSMShsm™ commands
    If you want to use DFSMShsm™ as your backup utility and the CICS® VR server address space is enabled, you must request that your user ID be authorized to issue DFSMShsm-authorized commands.
  - Understanding the CICS® VR scavengers
    Descriptions of the three scavengers that the CICS VR server address space runs: the history, server and inventory scavengers.
- 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.
Edition notice
This is the information for CICS VSAM Recovery for z/OS. It applies to CICS VSAM Recovery for z/OS Version 6.1, 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.

Activate the CICS® VR server

If the CICS® VR server fails, it restarts automatically, up to a maximum of six times. If this limit is exceeded, the automatic restart mechanism is disabled and CICS® VR terminates. You can restart the CICS® VR server.

When you have resolved the problem, you can restart the CICS® VR server by using the VARY SMS,CICSVR,ACTIVE command. When the CICS® VR server is restarted, the following message is displayed on the operator console:

Figure 1. VARY SMS,CICSVR,ACTIVE results

 DWW014I  CICSVR SERVER ADDRESS SPACE IS NOW ACTIVE.

VARY SMS,CICSVR,ACTIVE is also needed to restart the CICS® VR server after the VARY SMS,CICSVR,TERMINATESERVER command is issued. Also, the CICSVR_INIT parameter in the SYS1.PARMLIB IGDSMSxx member must be set to YES for successful completion of the VARY SMS,CICSVR,ACTIVE command.

Note:

If a failure occurs during the initialization of the CICS® VR server address space, automatic restart is not performed.
