Understanding the Working Set of Attribute Values

PXMCFG maintains a working set of attribute values for objects you define in your

Pathway/XM environment. These objects include NODE, SERVER, TCP, TERM,

PROGRAM, ROUTER, and SERVICE objects.

The working set of attribute values is initialized when you start PXMCFG. In this initial

stage, each attribute entry in the working set specifies either of the following:

•

The attribute and its default value, assigned by PXMCFG. If you do not specify

another value for this attribute with the SET or ADD statement, this default value is

assigned when you add any object of this type.

•

The attribute alone, with no value specified. You must assign a value for this

attribute with the SET or ADD statement.

By using values from the PXMCFG working set whenever possible, you can greatly

simplify object definition and creation. For example, the following statement creates a

SERVER object named FRED, using the current values from the working set:

ADD SERVER FRED

The following paragraphs describe how to display, modify, override, and reinitialize

working-set values.

Establishing and Modifying Working-Set Values

As you configure and add objects to your Pathway/XM environment, you can establish

or modify the attribute values in the PXMCFG working set by using the SET statement.

For example, you can specify the number of guaranteed server-process reservations for a

distributed server class by entering:

SET SERVER NUMSTATIC 2

Each time you enter the ADD statement, PXMCFG assigns the working-set values last

established for that object type (unless you override these values with new ones in the

ADD statement). This feature allows you to use the PXMCFG working set as a

template for defining and adding multiple objects of the same type with identical or

similar attribute values.

For example, the following statements add four SERVER objects to your Pathway/XM

environment.

SET SERVER TYPE DISTRIBUTED

SET SERVER NUMSTATIC 1

ADD SERVER FRED, PROGRAM \*.$MKT.SALES.HIST

ADD SERVER JOAN, PROGRAM \*.$MKT.SALES.PROJ

SET SERVER NUMSTATIC 2

ADD SERVER DON, PROGRAM \*.$MKT.SALES.ANAL

ADD SERVER MARY,PROGRAM \*.$MKT.SALES.ADMIN, AUTORESTART 1

Note. Do not use PXMCFG or PXMCOM reserved words to identify Pathway/XM objects. For

a list of reserved words, refer to Appendix B.
