ALTER TMF

The ALTER TMF command changes the TMF configuration volume or switches the

functions of the TMP’s primary and backup processes.

CONFIGVOL volume

specifies the name of the volume that contains the configuration files to be used in

the next TMF startup. The volume must be accessible by the TMFMON2 process,

which creates other TMF processes during TMF startup.

SWITCHPROCESS TMP

switches the function of the TMP’s primary and backup processes, effectively

changing the primary process to the backup and vice-versa.

Security Restrictions

You can use the ALTER TMF command only if you are a member of the super user

group.

TMF State Requirement

Before you can enter the ALTER TMF command with the CONFIGVOL volume option,

TMF must be stopped. However, you can enter the ALTER TMF command with the

SWITCHPROCESS TMP option at any time, whether or not TMF is running.

Usage Guidelines

With the ALTER TMF command, you can select either of two operations: changing the

TMF configuration volume or switching the TMP’s primary and backup processes.

When entering an ALTER TMF command, you select one or the other of these

operations, but not both.

Changing the TMF Configuration Volume

With the CONFIGVOL option, the ALTER TMF command causes the TMP process to

change the TMF configuration volume and then stop itself. The new TMP process, re-

created automatically, uses the new configuration volume. If there are no configuration

files located in the ZTMFCONF subvolume on that volume, the TMP creates new ones.

ALTER TMF, {CONFIGVOL volume }

{SWITCHPROCESS TMP}
