cable is disconnected or the printer is powered off.
3.4.4 Purging the Symbiont Process’s Working Set
The DCPS symbiont purges its working set after it has been idle for a period of
time in order to conserve system resources. The time delay is intended to help
prevent the system from thrashing by keeping the program in physical memory
while more work is apt to arrive.
By default, DCPS waits ten (10) minutes after becoming idle before purging its
working set. You can increase this value, if desired, by defining a system-wide
logical:
$ DEFINE/SYSTEM/EXECUTIVE DCPS$PURGE_TIME "0 hh:mm:ss.00"
where hh:mm:ss.00 is an OpenVMS delta-time value specifying the desired
time delay. If the value is less than the default of ten seconds, the default is
used.
3.4.5 Suppressing the OPCOM Message ‘‘User Name Not Found’’
When DCPS is executing in a cluster environment where the UAF files are
different between cluster members, an OPCOM message is displayed and the
job prints normally:
%%%%%%%%%%% OPCOM 1-MAR-2001 18:43:55.87 %%%%%%%%%%%
Message from user SYSTEM on LITERA
Queue SHARIE: %DCPS-W-USERNOTFOUND, user name FOO not found,
no log files created
-RMS-E-RNF, record not found
Because the username cannot be found, the symbiont cannot perform the
MESSAGES=KEEP or MESSAGES=PRINT parameter request.
To keep this OPCOM message from being displayed for every job:
$ DEFINE/SYSTEM/EXECUTIVE DCPS$queuename_IGNORE_UNKNOWN_USER 1
3.4.6 Using Old ANSI Translator Page Size for A4 Landscape
All versions of the ANSI translator prior to DCPS V1.1A had a problem
printing 66 lines of text in landscape mode on A4 paper. Certain printers
have slightly smaller than average print areas when using A4 paper, which
resulted in the 66th line being lost or clipped when using print parameters of
PAGE_SIZE=A4,PAGE_ORIENTATION=LANDSCAPE .
The ANSI translator now correctly prints 66 lines of text in landscape mode
on A4 paper. The fix involved changing the vertical spacing of the font used
(SGR 15) and correcting the maximum printable area for A4 paper.
