Example
For example, the following sequence of PXMCFG statements defines a SERVER object
and then adds it under the server-class name ORDER-SRV:
RESET SERVER
SET SERVER NODE SERVER-1
SET SERVER PROGRAM $DATA.SRVRS.ORDSRV
SET SERVER GROUP ORDERS
SET SERVER GROUP THURSDAY
SET SERVER CMON ON
SET SERVER HIGHPIN ON
SET SERVER MAXSERVERS 5
SET SERVER NUMSTATIC 3
SET SERVER NONSTOP 0
SET SERVER TMF ON
SET SERVER ASSIGN ORDERS, $DATA.REG1.ORDFILE
SET SERVER ASSIGN PARTS, $DATA.REG2.PARTFILE
SET SERVER PARAM SWITCH-1 “ON”
ADD SERVER ORDER-SRV
The SET statements in this example establish the following characteristics for the
SERVER object:
•
The system and the CPU resources used for server processes in this server class, as
well as any specified attribute defaults, are defined in the NODE object SERVER-1.
•
The object code for the server class is stored in the file $DATA.SRVRS.ORDSRV.
•
The server class is managed as a distributed server class (because the TYPE
attribute is not specified and its default is DISTRIBUTED).
•
The server class is defined as a member of two server groups: ORDERS and
THURSDAY.
•
Before creating each new server process, Pathway/XM will send a message to the
user-supplied $CMON process, if any, allowing $CMON to approve or modify the
process startup parameter values.
•
Server processes in this server class will run using high PINs.
•
The total number of server process reservations that can be distributed for the server
class is 5.
•
The total number of server process reservations and started servers that are
permanently allotted to this server class per PATHMON process is 3.
•
Server processes in this server class will not be run as process pairs.
•
The relative priority at which processes in this server class will run is determined by
the setting of the PRI attribute of the NODE object SERVER-1 (because no PRI
attribute is specified for the server class).
•
Send operations from requesters to processes in this server class are allowed
whether or not the SCREEN COBOL or Pathsend requester program is in TMF
transaction mode.
