Interoperability and Versioning Issues

In some computing environments, you may find your TMFCOM process interacting

with a newer or older version of TMFSERVE. If the TMFSERVE does not support the

options introduced in the version of TMFCOM covered by this manual edition, the

following results apply:

•

A TMFCOM operational command (such as ALTER AUDITTRAIL or RECOVER

FILES) that specifies one of these new options fails with an error message.

•

A TMFCOM command that displays information (such as INFO AUDITTRAIL or

INFO CATALOG) does not present information related to the new option.

Table 3-2, TMFCOM and TMFSERVE Version Interaction: Operational Commands,

shows the behavior for operational commands when different versions of TMFCOM

and TMFSERVE interact.

Table 3-3, TMFCOM and TMFSERVE Version Interaction: Informational Commands,

shows the behavior for informational commands when different versions of TMFCOM

and TMFSERVE interact. Notice that in no cases are error messages returned.

The TMFCOM HELP command displays information about the new options only if

TMFCOM is connected to a current version of TMFSERVE.
