ALTER PROCESS
ZTMF-MAP-Alter-Processes
is an extensible structured token specifying the attributes of the process
configuration that are to be changed. This token is optional; only one occurrence
is allowed. This token contains the following fields:
ZCpusInfo
specifies from 1 to 16 different processors in which to run the process. See the
struct ZTMF-TYP-CpusInfo under Private Token and Field Types on page 4-6.
If the value is ZTMF-VAL-ResetCpusInfo, the CPUs for the process are reset to
the CPUs selected by the CMON process or by TMF.
The CPU is assigned as follows:

If the command specifies more than one CPU, the list is searched from
beginning to end to beginning again, until a CPU is found.

If the command does not specify a CPU and the operating system’s CMON
process is running, the CMON process chooses a CPU.

If the command does not specify a CPU and the CMON process is not
running, the following assignments take place:

For the BACKOUT, FILERECOVERY, and VOLUMERECOVERY
process types, TMF assigns the first available processor with the
fewest instances of the same process type.

For the TMP, TMF assigns the processors to which the $SYSTEM disk
is connected (typically Processors 0 and 1).

For all other configurable process types, TMF assigns the same
processors on which the TMP is running.
For the TMFMON2 process, the ZCpusInfo field has no effect.
ZPriority
specifies the execution priority for the process. Valid values range from
1 through 199.
If the value is ZTMF-VAL-ResetWord, the priority for the process is reset to the
priority selected by the CMON process. If CMON is not available, the system
uses the priority 204 for the TMP, 180 for TMFMON2, and 149 for all other
process types.
ZMakeSaveAbend
specifies whether an Inspect program save-abend file is created if the process
terminates abnormally. The following values are valid:
ZSPI-VAL-True A save-abend file is created.
ZSPI-VAL-False A save-abend file is not created.
