SEGMENTID
Access^group
Access^group is used to indicate which users are allowed to issue sensitive SCF or SPI
commands. If access^group is set to 0 (owner), then the process sending a request (a
$ZNET SPI message to GDSX) must have a process accessor ID that allows access to
the GDSX process.
If access^group is set to 1 (group), user^group is used to indicate the group ID of users
allowed to issue sensitive commands. If access^group does not equal 1, user^group is
not referenced by TSCODE.
If access^group is set to 2 (all), the sensitive commands can be issued by anyone. If
access^group is set to 3 (255,255), the sensitive commands can be issued only by the
super ID.
SEGMENTID
This static parameter allows you to specify the extended segment allocated by TSCODE
for various control and data structures. Segment ID 1025 is reserved by TSCODE for
tracing purposes. GDSX stops with abend error 30 if you set SEGMENTID to 1025.
SERVER
This static parameter allows you to run a GDSX application as if it were a NonStop
TS/MP server. See "Running GDSX as a NonStop TS/MP Server" on page 3-10 for
more information.
TASKCPSIZE
This static parameter specifies the size of the area for checkpointed memory pool buffers
that is allocated for each user task in extended memory. When a task checkpoints its
memory pool buffers by a call to ^CHECKPOINT(2), the data sent to the backup
process is stored in the task’s TASKCPSIZE-sized area.
This is the area that ^RECLAIMBUFFER traverses to recover buffer images after a
failure. See "^RECLAIMBUFFER" on page 8-61.
The size of the pool in bytes allocated by TSCODE for all user and system tasks is:
(TASKCPSIZE * 2) * (MAXTASKS + 5)
