To exercise the CA Dynam/T interface, each system must define the same range(s) of volume serial numbers in its respective catalog. If the CA Dynam/T catalog contains volumes not defined in the CA 1 Tape Management Catalog (TMC), the CA 1 utilities TMSXTEND or TMSFORMT must be executed to extend the TMC and add the volumes. If the CA 1 TMC contains volumes not defined to CA Dynam/T, the undefined volumes are added to the CA Dynam/T catalog automatically when the database synchronization utility DYNSYNC is executed.
After being initially defined during installation, the databases of each interfacing system must be synchronized to establish that there are no differences. This synchronization must be maintained throughout all activity to ensure the integrity of the databases. Should queue-related problems prevent information from being shared between CA 1 and CA Dynam/T, a synchronization utility is provided to help resolve discrepancies between the databases.
An extract utility is supplied with each system to convert database information into a common format that can be compared to determine if any discrepancies exist between the systems. CA recommends that the CA Dynam/T VM extract be put on tape, as VM cannot write to a sequential data set using MVS access methods. Any other extract(s) is stored on DASD.
Volumes in delete status are not placed in the extract. If these volumes are active under CA Dynam/T, the synchronization utility generates a message indicating that the volume could not be found on the extract for CA 1.
The synchronization utility accepts the extracts from each system as input and performs the analysis. All discrepancies are indicated on an exception report and information relative to resolving the discrepancies is sent to the appropriate system for corrective action through separate data sets.
Each system provides a product-specific update utility used to apply synchronization information to its respective database. Any updates that cannot be performed are detailed in error reports. These errors may require additional research and manual correction.
