TS/MP 2.5 System Management Manual

• CREATEDELAY specifies the maximum amount of time, ACS subsystem processes or TCP
process must wait to use an established link to a server class before the PATHMON process
starts another server process.
• DELETEDELAY specifies the maximum amount of time a link between ACS subsystem processes,
or TCP process and a dynamic server process can remain idle before the ACS subsystem
processes or TCP process automatically returns the link to the dynamic server.
The CREATEDELAY and DELETEDELAY attributes have the potential to dramatically impact
system performance. See “Configuring Links for Optimum Performance” (page 66).
• DEFINE assigns a DEFINE definition as part of a server class definition. You can use DEFINEs
to specify the default volume and subvolume and to specify files used by the server.
• MAXSERVERS specifies the maximum number of server processes in this server class that can
be run simultaneously.
• MAXLINKS specifies the maximum number of links to a server process from all TCPs and ACS
subsystem processes.
• NUMSTATIC specifies the maximum number of static server processes allowed within this
server class. Static server processes are those that start in response to the START SERVER
command.
For a complete description of all the SET SERVER attributes, see “SERVER Commands” (page 177).
Attributes That Apply Only to Guardian Servers
These attributes are valid only for Guardian servers:
• ASSIGN assigns a logical file name to a physical file used by your server program and
specifies the attributes of that file.
You can include multiple ASSIGN specifications for a server class to cover as many files as
necessary. The ASSIGN specification sets up a correspondence between the name used for
a file by your server program and the name by which the TACL command recognizes this file.
If your server program is written in COBOL, you use this attribute to override a program file
assignment made in the SELECT clause. Among the file attributes that you can specify with
ASSIGN are disk extent size, access exclusion mode, file code, and record and block size.
• IN specifies the name of the input file passed to the server in the startup message. It can be
a DEFINE name. If you omit this attribute, spaces are passed to the server.
• OUT specifies the name of the OUT file passed to the server in the startup message. It can be
a DEFINE name. If you omit this attribute, spaces are passed to the server.
• PARAM assigns a string value to a parameter name, which the PATHMON process then sends
in a PARAM message to each server process as it starts. You can include multiple PARAM
specifications for a server class, just as you can include multiple ASSIGN specifications. (If
you specified a backup processor for the processor attribute, the PATHMON process
automatically adds a PARAM for the backup processor to the PARAM message.)
• STARTUP specifies a character string sent to the server in the startup message.
• VOLUME specifies the volume and subvolume names to be passed to the server in the startup
message. If you omit this attribute, the defaults are those set with the CMDVOL command.
These commands defines a Guardian SERVER object and then adds it under the server class name
