CICS VR Overview
Getting Started
- Introducing CICS® VR
  CICS® VSAM Recovery Version 6 Release 3 (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 6.3. 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.
  - Running CICS® VR JCL customization
    CICS® VR JCL customization is an optional step that assists you to customize the CICS VR sample jobs, clists, and ISPF dialog skeletons.
  - LPALST updates
    Add the library DWW.V630.SDWWLPA to the LPALST. To add the library dynamically to the LPALST issue the SETPROG command.
  - LNKLST updates
    Libraries need to be added to the LNKLST concatenation for the CICS VR server.
  - SYS1.PARMLIB updates
    The parameters required to activate the CICS VR server address space are discussed here with some example settings.
  - Define the RCDS data sets
    To allocate your final RCDS data sets so that they can both be used by the ISPF interface and the server address space, you must follow the RCDS naming convention.
  - Activating the CICS VR server address space
    The commands that are required to activate the CICS VR server address space.
  - Setting up the ISPF interface
    To run IVP jobs the ISPF interface must be set up first, using the sample JCL and pre-allocated data sets.
  - Running the IVP jobs to verify your CICS VR installation
    When you have completed the installation of the CICS VR server address space you run the following IVP jobs to verify your installation using the following CICS VR installation verification procedures (IVPs) to confirm that CICS VR is operational. You must also run the CLIST to activate the ISPF interface in order to complete the IVP process.
    - The DWWASMLI job
      The first IVP job to run is an assemble and link job for one of the sample exits. You can use this exit to examine and modify a before or after image before it is applied to the VSAM data set.
    - The DWWRCDEF job
      The DWWRCDEF job is optional and is run to allocate RCDS data sets intended only for the IVP process.
    - The DWWVRDEF job
      The DWWVRDEF job produces four data sets when it is submitted successfully.
    - The DWWRUNBL job
      The DWWRUNBL job updates the sample VSAM cluster created by the DWWVRDEF IVP job.
    - DWWCLIST - ISPF dialog interface
      The next step to verify the CICS® VR installation requires activating the CICS VR ISPF interface.
    - The DWWCLNUP job
      The DWWCLNUP job is optional, it is run to delete the test data created by the IVP jobs.
- 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.

The DWWCLNUP job

The DWWCLNUP job is optional, it is run to delete the test data created by the IVP jobs.

Run the DWWCLNUP job from your customized SDWWCNTL.OUT data set. If you have not performed customization, copy member DWWCLNUP from the SDWWCNTL data set and update the following variables:

SET THLQ=DWWUSER.V630
SET PREF=DWWUSER.V630
SET SUFF=PROD

When the job is successfully submitted these data sets are deleted:

DWWUSER.V630.CUSTOMER
DWWUSER.V630.CUSTOMER.DATA
DWWUSER.V630.CUSTOMER.NEW
DWWUSER.V630.CUSTOMER.NEW.DATA
DWWUSER.V630.DWWCON1.GRPPROD
DWWUSER.V630.DWWCON1.GRPPROD.DATA
DWWUSER.V630.DWWCON2.GRPPROD
DWWUSER.V630.DWWCON2.GRPPROD.DATA
DWWUSER.V630.DWWCON3.GRPPROD
DWWUSER.V630.DWWCON3.GRPPROD.DATA

Before deleting the RCDS data sets, ensure that the CICS VR server address space is terminated. If you do not want to delete the RCDS data sets, specify blank values for the PREF and SUFF variables:

SET THLQ=DWWUSER.V630
SET PREF=
SET SUFF=
