(Optional) Analyzing IMS data set placement for System Level Backup validation

If a System Level Backup created by IMS Recovery Expert will be used to restore an entire IMS environment, there are strict guidelines on how IMS is configured on your local DASD.

About this task

These utilities require the segregation of the active logs, RECONs, and IMS system data sets from the database data. They also require the MVS user catalogs where the data sets of an IMS system are to be backed up and restored with the IMS system.

The IMS Recovery Expert System Setup facility collects and displays information about the IMS system's user catalogs, IMS system data sets, active logs, and related IMS database data sets. Before a System Level Backup can be created, IMS Recovery Expert validates that the data sets are separated by volume. This ensures that valid system restores can be done based on options specified in the backup profiles.
Note: It is highly recommended that you analyze data set placement before attempting the first System Level Backup.

Procedure

  1. On the IMS Recovery Expert main menu panel (BSY$MAIN), specify 1 (System Operations) on the Option line and press Enter.

       The System Backup and System Restore utilities are the fastest and most      
       effective backups available for IMS.  In order for this utility to be        
       effective, there are very strict guidelines on how IMS is configured on your 
       local DASD.  This utility requires the segregation of the Active logs and    
       RECON datasets from the database data.  It also requires that the MVS User   
       catalogs where the data sets are catalogued to be backed up and restored     
       with the IMS system. This utility will help you in getting your IMS system   
       available for System Backup and System Restore Utilities.                    
    

  3. On the Enter IMS System or Group panel (BSY$SSIW), specify an IMS system or group and a backup method.
    1. To choose from a list of IMS systems, specify ? in the IMS System field and press Enter.
