SNAX/HLS Configuration and Control Manual

Command Dictionary
Using the HLSCOM Utility
6–10 104705 Tandem Computers Incorporated
events are logged and/or sent to EMS. The text of messages produced on the log
is not affected.
Changing the RDT file introduces a new set of profiles to SNAX/HLS. Sessions
already allocated are not affected. If the new RDT file cannot be allocated, the old
RDT file remains in effect.
Changing the backup CPU number from -1 (indicating that there is no backup) to
a real value (in the range 0 through 15) causes the backup to be initiated.
Changing the backup CPU number from a real value to -1 stops the current
backup. Changing the backup CPU number from a real value to another real
value stops and restarts the backup. You cannot set the backup CPU number to
the same CPU as is running the primary.
The BACKUPDEBUG configuration parameter takes effect only when a backup
process is next started; it has no effect on any backup currently running. This
option corresponds to the BACKUPDEBUG configuration parameter on the
startup line. See Section 5, “Operating SNAX/HLS” for a discussion of this
configuration parameter.
The CHARMAPFILE alters the name of the current character map file. This file
defaults to $SYSTEM.SYSTEM.ZCHARMAP. This file only has to be present if a
mapping other than the standard ASCII-to-EBCDIC translation is to be employed.
The CHARMAPNAME alters the name of the default character mapping table,
which must exist in the current character map file. The default map name is
originally set by the startup parameter CHARMAPNAME, which itself defaults to
the standard ASCII<->EBCDIC mapping. Once a default map is specified for the
process (that is, not the standard ASCII<->EBCDIC translation), this standard map
becomes unavailable.
The DEBUGONERROR configuration parameter causes the primary process to
enter INSPECT (or DEBUG) when an internal error is detected. See Section 5,
“Operating SNAX/HLS” for more information.
Changing the value of the TWOSTEP parameter can affect the amount of resources
consumed by the HLS process and the processing time. In general, a low value
uses fewer resources but greater processing time. If you specify zero, two-step
reads are disabled.
Changing the value of the SSCPTEXTSIZE limit can affect the size of reads issued
by HLS on sessions whose profiles have specified the WANT-SSCP-TEXT option.
Examples
This command changes the primary EMS collector to which events are sent on the
\AUSTIN node.
@ ALTER EMS \AUSTIN.$0
This command changes the log file to $NULL and also switches to the new RDT file,
NEWRDT.
@ ALTER LOG $NULL, RDT NEWRDT
