EDM support for running a newly installed Control-M/Tape version and an earlier Control-M/Tape version in parallel

The following topics describe how to modify the External Data Manager (EDM) so that both versions work in parallel:

• Installing parallel EDM support with earlier Control-M/Tape versions
• Removing parallel EDM support with Control-M/Tape

The interface between an EDM and Control‑M/Tape is achieved using a Tape Volume exit of the EDM. Sample Tape Volume exits for interfacing with each type of EDM are supplied with the installation tape.

When more than one Control‑M/Tape version runs at the same time (for example, in parallel), the Tape Volume exits that interface with each version must be modified so that they perform the same functions. This ensures that the two databases are updated and kept synchronized.

Note: The text shown below is a general description of Control‑M/Tape EDM support during parallel execution. For more information about support for specific EDMs, see "External Data Manager Support" in the Control‑M/Tape Implementation Guide.
