Defining Attributes for Guardian and OSS Servers
processor specified as a backup. This parameter is passed to the server as part of
the PARAM message. As it creates the server processes, the PATHMON process
uses the primary CPUs in the order specified. If a processor is down, the
PATHMON process uses the backup processor as an alternate processor and
passes the primary processor number as the backup processor parameter.
•
CREATEDELAY specifies the maximum amount of time a LINKMON 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 a
LINKMON or TCP process and a dynamic server process can remain idle before
the LINKMON 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 on page 3-23.
•
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 LINKMON 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 Section 12,
SERVER Commands.
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.
