CICS VR Exits
- Using the CICS® VR archive exits
  Documentation of intended Programming Interfaces that assist you to write exits for CICS® VR archive and log stream copy utilities.
  - What you can use the exits for
    The CICS® VR archive and log stream copy exits let you perform special processing at two different exit points.
  - How the archive exits work
    Before you start using an exit, you must know how it works with the CICS® VR archive utility and log stream copy utility. The interface conventions for passing control and information between the archive utility or the log stream copy utility and the exit programs are described here.
  - Precopy exit: process a copy of the log record
    Use the precopy exit to copy each log record to another data set, before the archive utility or log stream copy utility copies the record to the output data set
    - When the exit is called
      This exit is called just before each log record is copied to the output data sets.
    - Parameter list
      The parameter list that is passed to the precopy exit.
    - Parameters passed to the exit program
      The parameters that are passed to the exit program.
    - Parameter returned from the exit program
      The parameter that is returned from the exit program.
    - Additional records in the log stream copy
      When a log stream copy (DWWLC) is performed, the records in the MVS™ log stream are copied to a sequential data set. In addition to the records in the MVS log stream, DWWLC writes two additional records to the output file, the first record and the last record, both called LOGI records.
  - Termination exit: terminate operations from the precopy exit
    Use the termination exit to stop the actions that were performed by the precopy exit, such as closing the data set that the precopy exit copied the log records to.
- Implementing exits for forward recovery and backout
  Description of intended Programming Interfaces that allow you to write exits for CICS® VR forward recovery and backout.
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 6.3, 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.

Parameter list

The parameter list that is passed to the precopy exit.

Log record, work area

Precopy exit parameters show how you find the parameters from the contents of register 1.

This figure lists the contents of the registers passed to the precopy exit used with the CICS VR archive or log stream copy utilities. Register 1 contains the address of the parameter list. The first fullword in the parameter list points to the log record. The second fullword in the parameter list points to the work area. Register 13 contains the address of the register save area. Register 14 contains the return address. Register 15 contains the exit program start address. — Figure 1. Precopy exit parameters

The figure shows the precopy exit parameters when the exit is defined without the OLD keyword. This is the recommended way to define the exit. With the OLD keyword specified, there is an extra level of indirection. Log record in the figure is the address of the log record, and Work area in the figure is the address of the work area. The OLD keyword allows compatibility with exits written for earlier CICS® VR releases, such as CICS® VR V3R3 and earlier, and CICS® VR V4R1 without apar PK28852 applied.
