ALTER PROCESS
Stopping and Restarting TMF Processes
Some types of TMF processes persist in the system but can be manually stopped and
restarted, as described in Table 3-4. Others are transient processes that start and stop
automatically as needed, as also noted in this table.
Table 3-4. Stopping and Restarting TMF Processes
Process Type How Stopped and Restarted
TMP To manually stop and restart the TMP process pair:
1. Issue a STOP TMF command to obtain a clean shutdown
of TMF.
2. Issue a STOP TMF, ABRUPT command to stop the TMP
processes. (This operation is equivalent to a controlled
TMF crash, which terminates both the primary and
backup TMPs. A new TMP process pair is created
automatically.)
3. Issue a START TMF command to restart TMF.
BACKOUT
CATALOG
To manually stop and restart all backout or catalog processes:
1. Issue a STOP TMF command to obtain a clean shutdown
of TMF. This action stops all processes of these types.
2. Issue a START TMF command to restart TMF. This
action restarts the processes.
An alternative way to stop and restart the backout or catalog
processes is by entering, through the TACL command
interpreter, a STOP process-name command for each
process. For the backout process-name, use $XBKn,
where n is a digit uniquely identifying the particular process;
for the catalog process pair, use $XCAT. After they are
stopped in this way, the TMP automatically restarts the
backout and catalog processes.
TMFMON
TMFMON2
The TMFMON and TMFMON2 processes are started
automatically during system cold load and processor reload,
and run until the system is shut down or a processor fails.
The only way to stop and restart these processes is to cold
load the system or shut down and reload individual
processors.
