Configure SCS Address Space Parameters

This section only applies if the default SCS address space values do not correspond with your environment settings.

To update SCS address space runtime parameters, update the MSMCPROC member in the library that the MSMCPARM DD card in the MSMCPROC procedure points.

You can update the following parameters: TCP/IP, SAF, and AUX.

TCP/IP

Specifies the address space parameters for the interface between the SCS address space and TCP/IP for communicating with other components of CA CSM.

The TCP/IP parameters are specified using the following attributes:

ipaddr

Specifies the IP address of the interface through which the SCS address space accepts TCP connection requests from other CA CSM components.

Limits: IPv4 address using standard dotted decimal notation.

(Optional) IPv6 address using one of the standard text forms that are defined in RFC 4291, IPv6

Example 1: 0.0.0.0

Example 2: ::

Note: The IPv4 unspecified address, 0.0.0.0, is used to indicate that the SCS address space accepts TCP connection requests through all IPv4 interfaces. The IPv6 unspecified address, :: , can be used to indicate that the SCS address space accepts TCP connection requests through all IPv4 and IPv6 interfaces.

Default: ::

port

Specifies the port number the SCS address space uses to listen for TCP connection requests from other CA CSM components.

Limits: 65535

Default: 49152

SAF

Sets the parameters that are related to the SCS address space interface to the System Authorization Facility (SAF).

The SAF parameters are specified using the following attributes:

application

Specifies the application name that is assigned to the SCS address space.

Limits: 1-8 bytes. The first character must be alphabetic or national. The remaining characters must be alphanumeric or national.

Default: MSMCAPPL

requestor

Specifies the name that is assigned to the SCS address space that assigns a unique control point within a set of control points that exist in a subsystem.

Note: If you specify a requestor name and IBM RACF is installed, update the IBM RACF router table with a matching entry. If you do not update the table, IBM RACF processing is bypassed.

Limits: 1-8 bytes. The first character must be alphabetic or national. The remaining characters must be alphanumeric or national.

Default: None

subsystem

Specifies the subsystem name, version, and release level that are assigned to the SCS address space.

Note: If you specify a subsystem name and IBM RACF is installed, update the IBM RACF router table with a matching entry. If you do not update the table, IBM RACF processing is bypassed.

Limits: 1-8 bytes. The first character must be alphabetic or national. The remaining characters must be alphanumeric or national.

Default: None

class

Specifies the resource class name that CA CSM uses for security rules in resource profiles.

Limits: 1-8 bytes. All characters of the name must be alphanumeric or national.

Default: CAMSM

AUX

Sets the parameters that are related to the SCS AUX address space.

The SCS AUX address space parameters are specified using the following attributes:

procname

Specifies the name of a JCL procedure library member that contains the source JCL for the SCS AUX address space.

Limits: 1-8 bytes. The first character must be alphabetic or national. The remaining characters must be alphanumeric or national.

Default: MSMCAUX

jobname

Specifies the job name that is assigned to the SCS AUX address space.

Limits: 1-8 bytes. The first character must be alphabetic or national. The remaining characters must be alphanumeric or national.

Default: The JCL procedure library member name (if the source JCL is a procedure), or the job name that is assigned on the JOB statement (if the source JCL is a job).

reusasid

Determines if a reusable ASID is requested for the SCS AUX address space.

The SCS AUX address space receives one of the following values:

YES

The SCS AUX address space is assigned a reusable ASID if REUSASID (YES) is also specified in the DIAGxx PARMLIB member.

NO

The SCS AUX address space is not assigned reusable ASID.

Default: YES

Note: Using a reusable ASID results in an ABEND of system 0D3 if products or programs that are used in the configuration of a CA Technologies product are not upgraded to tolerate reusable ASIDs.

See the IBM z/OS MVS Programming: Extended Addressability Guide for more information about reusing ASIDs.

maxactive

Specifies the maximum number of concurrently active SCS AUX address spaces.

Limits: 1 to 20 numeric

Default: 20
