Backup creation through the CICS VR panel interface

CICS® VR can create backups configured through the panel interface, using a backup skeleton.

The skeleton is stored in SDWWSENU, and contains the details of the job to submit for the specific backup product. A base skeleton is provided in DWWRE1RO, and can be customized for the specific backup product.

Several CICS VR variables are available for use within the backup skeleton, as described below:
Table 1. Backup skeleton variables supported by CICS VR
Variable name Description
&CSPH The original sphere name
&CBKDSN The backup sphere name
&CBKCSID The CICS APPLID, if backup type 2 is specified
&CBKTYPE The backup type value. This can be 1, 2, or 3, and is specified on the panel interface
The name of the customized skeleton is in the form DWWprdnm, where prdnm is a five character product name abbreviation, with the digit '1' in the third place. For example, a product name HSMLB would produce a skeleton name DWWHS1LB. The sample skeleton uses IDCAMS REPRO, and so has the name DWWRE1RO.
Note: The same backup name is used for restore and backup. For example, to restore from a backup made using IDCAMS REPRO, select the REPRO product. Similarly, to make a backup using IDCAMS REPRO, select the REPRO product. CICS VR uses the correct skeleton in the resulting job.
After the backup step within the skeleton, a file copy notification can be performed. This is done by executing a program which calls the CICS VR File Copy Notification Service.
Note: File copy notification from within the backup skeleton must be performed only if the backup product does not include a call to the CICS VR notification service already.
