Configuring a New Subsystem Into DSNM
•
The following are changes to the processing of the DSNM configuration file:
•
If no DSNM configuration file is specified, each DSMS process uses the file 
named DSNMCONF, located on the same subvolume as the object file of the 
process.
•
If a nonexistent DSNM configuration file is specified (explicitly or by default), 
the DSNM processes behave as if the file is present, but empty. 
•
All DSNM configuration file parameters for DSMS processes supplied by 
Tandem now have internal default values.  Additionally, a number of DSNM 
configuration file parameters have been added or altered for C31 and subsequent 
releases. Refer to the Distributed Systems Management Solutions (DSMS) 
System Management Guide for the complete description of a DSNM 
configuration parameters.
•
The following are changes to the processing of the $SYSTEM.SYSTEM.DSNM 
file:
•
If $SYSTEM.SYSTEM.DSNM does not exist or is unreadable, each DSMS 
process uses the default DSNM configuration file (DSNMCONF) and the 
default value STARTUP PARAMS YES.
•
The CONFIG parameter in $SYSTEM.SYSTEM.DSNM is now optional. If 
present, it may contain a search list of one to three files, all of which must be in 
the format of a DSNM configuration file. (The specified files are searched for 
parameters in the order listed.)  If CONFIG is absent, the default DSNM 
configuration file is used. In either case, $SYSTEM.SYSTEM.ZDSNCONF is 
searched for parameters after all other DSNM configuration files. Refer to the 
Distributed Systems Management Solutions (DSMS) System Management Guide 
for details on the search order.
•
Comments are now allowed in the $SYSTEM.SYSTEM.DSNM file.
The $SYSTEM.SYSTEM.DSNM File
$SYSTEM.SYSTEM.DSNM is an edit file that all DSNM processes in a production 
environment read as part of their startup function. It points to the DSNMCONF file 
from which configuration parameters are retrieved, and specifies whether parameter 
values in the DSNMCONF file can be overridden by parameter values from the startup 
message (startup message parameters are discussed in Section 5, “DSNM Process 
Startup Functions”). 
Note. In a test environment, you specify a DSNMCONF file with the CONFIG process 
parameter in your I process RUN command.
