Stopping and Restarting Processes

When you change the process configuration for a TMF process, you must stop and

then restart the process to enable the new configuration to take effect.

To stop and then restart a TMF process, take the steps described here for the specific

type of process you want to stop and restart:

•

TMFMON and TMFMON2 processes

Stop and then restart the system.

•

TMP

1. Stop TMF to obtain a clean shutdown with all active transactions completed.

2. Stop TMF abruptly to stop and then recreate the primary and backup TMP

processess.

3. Restart TMF.

•

Backout and catalog processes

Stop and restart TMF. The TMP then restarts the process automatically.

TMFMON2

$SYSTEM.SYSnn.TMFMON2

TMP

$SYSTEM.SYSnn.TMFTMP

Volume recovery

$SYSTEM.SYSnn.TMFVRCV

Caution. If the SWAP, TERM, or PROGRAMFILE attribute for the TMFMON2 process is

modified so that the swap volume, terminal, or program file is inaccessible when a processor is

reloaded, the attempt to create the TMFMON2 process in that processor fails. Then TMF tries

again to create TMFMON2 in this processor, this time ignoring the configured value of the

attribute causing the problem and using that attribute’s default value instead. Although TMF

starts this TMFMON2 process with one or more default values, the configuration attributes are

not permanently modified. Thus, if the attribute values no longer cause errors when future

TMFMON2 processes are created, these new processes run with the configured values rather

than the defaults.

Until successful, TMF attempts to start the TMFMON2 process every 60 seconds. For each

failed attempt, TMF issues an EMS event message 184 to explain the problem.

If you alter the program file name for a TMF process, the change is persistent across cold

loads. Before loading a new SYSnn system image, you should issue the following TMFCOM

command to reset the program file names for all TMF processes to the appropriate defaults:

TMF 70> ALTER PROCESS *, RESET PROGRAMFILE
