CA GSS Initialization Parameter Overview

Last update July 27, 2014

The CA GSS started task locates the member that contains the initialization parameters through &MEMBER and the PARMLIB DD statement. CAW0OPTN(RUNPARM) is the default data set member that contains the parameters. During the CA GSS initialization, ISERVE reads this member (and possibly others) to obtain information about CA GSS operation.

Depending on your CA products, you can customize certain CA GSS initialization parameters. Unless otherwise noted, specify parameters on an as-needed basis. The following table provides an overview of these parameters and helps you determine which ones to customize.

Parameter

Description

Required?

ADDRESS

Identifies an ADDRESS environment and its associated load module.

Required for any external environment that is being accessed in an IMOD using an ADDRESS instruction.

Most products that CA GSS supports require an ADDRESS statement.

ALTNAME

Defines an alternative name for an address.

Most products that CA GSS supports (such as CA SYSVIEW®  Performance Management) may require an ALTNAME statement if you change the default name for an ADDRESS environment that the product supplies.

CMD

Adds a CA GSS/ISERVE operator command.

Not required.

COMMAND

Defines a word that can be issued as an operator console command to execute an IMOD.

Recommended once for each CA GSS/ISERVE operator command.

DB2PLAN

Identifies the DB2 plan that should be used for dynamic SQL requests.

Required if you are using the DB2() built-in function.

DUMP

Routes CA GSS and REXX dumps to a specific user or SYSOUT class.

Required.

EDITOR

Defines default data sets for the IMOD editor and the CA‑GSS/ISERVE Operator Control Panel.

Required.

EVENTS

Determines the size of the internal EVENTS table.

In most cases, the default value of 1,000 is sufficient. However, you should increase this value if you receive S502 abends during normal processing.

FUNCTION

Identifies an external function and its associated load module.

Required if you are running IBM Tivoli NetView or you have written your own functions.

GLOBVAL

Defines a REXX global variable and assigns it an initial value.

Not required.

GOALNET

Defines a GoalNet node.

Required if you are using the CA‑GSS GoalNet component.

GOALNETLOCAL

Declares the GoalNet name for the local system.

Required if you are using the CA‑GSS GoalNet component.

HELPDSN

Identifies the ISPF panel library that contains the help panels for CA GSS.

Not required.

ILOG

Defines an ILOG data set.

Required if you are using ILOG data sets or CA Insight™ Database Performance Monitor for DB2 for z/OS.

INCLUDE

Nests parmlib members.

Not required.

INSIGHT

Provides parameters for the CA Insight Database Performance Monitor for DB2 for z/OS initialization IMOD.

If you are using CA Insight, check your documentation to see whether your release of CA Insight provides an initializationIMOD and, if so, what parameters to pass it.

ISET

Defines an ISET for loading IMODs.

Required by CA Jobtrac®  Job Management.

JESNODE

Specifies the name of the JES node where this CA‑GSS started task is executing.

Required if you are using CA Jobtrac in a multisystem environment.

JOBTRAC

Provides parameters for the CA Jobtrac Job Management initialization IMOD.

If you are using CA Jobtrac, check your documentation to see whether your release of CA Jobtrac provides an initialization IMOD and, if so, what parameters to pass it.

LOGLINES

Determines the maximum number of lines written to the ISRVLOG.

If omitted, the maximum is determined by the system limit on spool data sets.

LOGON

Defines and activates the Logon Facility.

Not required.

MAXSTACK

Limits the default size of IMOD stacks.

Not required.

MAXXREQ

Determines the maximum number of active, cross memory requests.

Not required.

PRIMARY

Indicates whether this CA‑GSS address space is the primary one.

Not required.

PRODUCT

Identifies installed CA products that require special CA‑GSS support.

Required if you are using CA Insight.

SCHEDULE

Executes a list of IMODs immediately after the system initializes.

Not required.

SECURITY

Indicates what type of security software is installed on your system.

Required if you are running CA‑GSS on a system where SAF‑compatible security is in use.

SLICE

Determines the maximum number of REXX clauses that an IMOD can execute before relinquishing control to another IMOD.

In most cases, the default value is sufficient.

Default: 10000

SSID

Provides the subsystem name for another product with which CA GSS interacts.

Required if you are using CA OPS/MVS®  Event Management and Automation or CA SYSVIEW, or if the DB2 address space that CA GSS communicates with has a subsystem name other than DSN.

SSNAME

Defines a subsystem name for this CA GSS address space.

Required.

Default: ISRV. Do not change the value unless you are starting a secondary ISERVE.

STORAGE

Forces CA GSS work areas into 24-bit addressable storage.

Required on MVS/XA systems.

TCP/IP

Enables use of the TCP/IP communications protocol.

Not required.

TRACE

Sends trace output to the CA‑GSS ISRVLOG data set.

Not required.

USER

Provides parameters for the installation-provided initialization IMOD.

Not required.

VIEW

Provides parameters for the CA View® initialization IMOD.

If you are using CA View, check your documentation to see whether your release of CA View provides an initialization IMOD and, if so, what parameters to pass it.

VIOUNIT

Defines the unit name for virtual I/O (VIO) requests.

Required if you are using any unit name other than VIO in your z/OS system generation.

VTAMRESTART

Indicates what action CA GSS should take if VTAM fails and restarts.

Required if you are using the CA GSS GoalNet component.

Provides criteria for intercepting WTO messages and executing IMODs based on them.

Required if you are using either of these CA products:

  • CA Insight
  • CA Jobtrac
