Abstract

Disclosed is an automatic backup and restore control system for VSE/SP which records pertinent information about user and system datasets to time release the execution of backup utility operations. There are several access methods used for VSE/SP system and application datasets. VSE/SP system libraries have an access method of their own and require the use of the LIBR utility to perform backup and restore operations, while the ICCF library requires the use of the ICCF utility DTSUTIL. Application datasets generally utilize the VSAM, BDAM, or SAM access methods. DL/I and SQL/DS use a variation of VSAM, and again require specialized backup and restore utilities.

Automatic Backup And Restore Control System for VSE/SP

       Disclosed is an automatic backup and restore control
system for VSE/SP which records pertinent information about user and
system datasets to time release the execution of backup utility
operations.  There are several access methods used for VSE/SP system
and application datasets.  VSE/SP system libraries have an access
method of their own and require the use of the LIBR utility to
perform backup and restore operations, while the ICCF library
requires the use of the ICCF utility DTSUTIL.  Application datasets
generally utilize the VSAM, BDAM, or SAM access methods.  DL/I and
SQL/DS use a variation of VSAM, and again require specialized backup
and restore utilities.

      There is no single facility to tie the various utility programs
all together.  Current technology demands that a comprehensive VSE/SP
backup control system be manually operated.

      In accordance with this invention, a dataset catalog is
maintained on-line via a CICS transaction.  At a time of day
convenient to users and operations, a scan utility will sweep the
dataset catalog looking for entries that are currently (or past) due
for backup.  Upon finding an eligible entry, the scan job will then
build the appropriate JCL stream using the information from the
dataset catalog. A second job step is included in the stream to
update the backup catalog with information about the successful
completion of the previous backup job s...
