Process Options and Startup Parameters
CHARMAPFILE filename
specifies the name of the file that the subsystem searches for character set tables.
If you omit this parameter, the file $SYSTEM.SYSTEM.ZCHARMAP is used.
CHARMAPNAME mapname
specifies the name of the default character-map translation table. This table is
found in the character-map file specified by the CHARMAPFILE parameter. If you
omit this parameter, the standard ASCII-EBCDIC table is used.
COLLECTOR procname
specifies the primary event collector. If omitted, the collector named $0 on the local
node is used. If the COLLECTOR parameter is included without an accompanying
procname argument, no event messages are sent to the primary collector.
COLLECTOR-1 procname
COLLECTOR-2 procname
COLLECTOR-3 procname
specifies an alternate event collector (1, 2, or 3, respectively). If the
COLLECTOR-n parameter is omitted or included without an accompanying
procname argument, no event messages are sent to the corresponding collector.
DATAPAGES pages [E[XTENSIBLE]]
specifies a total amount of storage allocated for use as general dynamic memory.
pages is the number of pages to be allocated (at 2048 bytes per page) in the
range 0 through 2046 (for process versions earlier than D10) or 0 through 65280
(for later-version processes).
If you specify pages as 0, the process allocates pages dynamically, or as needed.
The process makes an initial allocation, always sufficient for process startup,
based on a variety of factors. After that, the process requests additional storage as
needed until approximately 4 MB has been allocated, the operating system limit on
segment size is reached, or disk space is exhausted. All versions of processes
create extensible segments by default. When starting a version D10 or later
process, you can explicitly request an extensible segment by appending E or
EXTENSIBLE to this parameter.
Dynamic allocation can be advantageous, but the danger is that memory cannot be
extended after the subsystem has been running for some time. If you can predict
memory requirements, specify an actual value for pages.
DEBUGONERROR value
specifies the action taken by a program when explicit tests detect a fatal error. If
enabled, the DEBUG procedure is called instead of ABEND. Take care when using
this feature: a backup does not take over until the offending primary process stops.
A value of TRUE, SET, ON, or YES enables debugging.
