CICS VR Overview
Getting Started
CICS® VR and CICS® TS
- Setting up CICS® VR for CICS® TS
  The tasks you need to do to set up CICS® VR for CICS TS.
  - Setting up your CICS® VR ISPF environment
    Using the CICS® VR panel interface can significantly reduce the amount of effort and time required to recover your VSAM data.
  - Understanding the recovery control data set
    The CICS® VR recovery control data set (RCDS) contains essential information for recovering your VSAM spheres.
  - Deciding which VSAM spheres to protect
    You want to be able to forward recover all VSAM spheres that are defined as CICS® files. Data sets that are read-only or browse-only do not need forward recovery or backout, however, back them up regularly in case they become unusable.
  - Creating groups of VSAM spheres
    When you have decided which VSAM spheres to protect, you can create groups of VSAM spheres that share common attributes, such as spheres that reside on the same volume or are updated by the same application, into groups.
  - Registering or deregistering your log of logs data sets
    All log of logs data sets must be registered in the RCDS for CICS® VR to know about them.
  - Setting up the log of logs scan utility (scan)
    The LOGOFLOGS scan utility scans all the log of logs that are registered in the RCDS, gathers information, and updates the RCDS with this information.
  - Setting up CICS® VR change accumulation
    CICS® VR CA reduces the time it takes to perform a forward recovery.
    - Step 1: Set up change accumulation batch jobs
      The first step is to create batch jobs that define CA groups and identify the spheres in each group.
    - Step 2: Use the change accumulation data sets in a forward recovery
      The second step occurs automatically when you use the CICS® VR ISPF dialog interface to forward recover a sphere.
    - Using change accumulation in a remote site recovery scenario
      If you want to periodically create change accumulation data sets and send them for use during forward recovery processing at a remote recovery site, you can consider using change accumulation with the options described in this section.
      - Specifying change accumulation options for remote site recovery
        The options used for change accumulation and remote site recovery.
      - Understanding change accumulation sequencing
        The first time a change accumulation batch job is run with the ONLY keyword specified for a change accumulation group, CICS® VR consolidates log records from the beginning of the specified log stream up to the time the job was submitted.
      - Using change accumulation data sets during forward recovery at a remote recovery site
        If you have periodically created change accumulation data sets using CA batch jobs with the ONLY keyword specified, you can use them to forward recover VSAM spheres at a remote recovery site, without having to send a copy of the primary site's RCDS to the remote recovery site.
  - Deciding if you want to use shadow copies
    You can reduce the time it takes to forward recover a VSAM file by creating a shadow copy of it.
  - Understanding CICS® VR automatic deregistration
    During the execution of various CICS® VR utilities, log of logs scan, backup notification, change accumulation, and so on. CICS VR stores information in the RCDS.
  - Implementing CICS® VR automatic deregistration
    The retention period values that you enter for CICS® VR automatic deregistration reflect your current environment and requirements.
- Setting up your CICS® TS environment
  This section describes the tasks you need to do to set up your CICS® TS environment for CICS VR.
- Using the CICS® VR file copy notification service
  This section primarily documents intended Programming Interface that allow the customer to write programs to obtain the notify service of CICS® VR.
- Using CICS® VR with CICS® TS at your disaster recovery site
  This section describes the tasks you need to perform to prepare your primary site and your remote site for disaster recovery using CICS® TS and CICS VR.
- Automated Recovery and Reorganization
  This section describes the tasks to perform when enabling automated recovery in CICS® VR V4R1.
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

Understanding change accumulation sequencing

The first time a change accumulation batch job is run with the ONLY keyword specified for a change accumulation group, CICS® VR consolidates log records from the beginning of the specified log stream up to the time the job was submitted.

The next time the same change accumulation job is run, CICS® VR consolidates log records from the time that the last change accumulation job stopped, up to the time the current job was submitted. The table Change accumulation sequencing for a sample CA group summarizes change accumulation sequencing for a sample CA group:

Table 1. Change accumulation sequencing for a sample CA group
Job run	First consolidated log record	Last consolidated log record
First run	First log record on the log stream	Last log record with a time stamp earlier than or equal to current job's submission time
All other runs	First log record with a time stamp later than previous job's submission time	Last log record with a time stamp earlier than or equal to current job's submission time

Note:

A date and time can be entered as a parameter of the BACKUPTIME keyword in the SPHERE command. If BACKUPTIME is specified, CICS® VR uses the entered data and time when determining the first log record to consolidate. Only log records that have a time stamp equal to or later than the specified date and time are consolidated. A separate BACKUPTIME keyword can be added for the ALL keyword and each NAME keyword in the SPHERE command if desired.
