HOLDMODE SPECIFIED

One of the following:

YES: Hold mode is in effect. For each console, pressing the ENTER key without entering a command will suspend or resume message rolling.
NO: Hold mode is not in effect for this system.

DEFAULT LOGON SPECIFICATION

The logon definition specified on the DEFAULT statement in CONSOLxx.

SYSTEM IS MEMBER OF SYSPLEX

One of the following:

YES: The system to which this console is defined belongs to a set of one of more systems in a multisystem environment. Programs in the system can use cross-coupling facility (XCF) services.
NO: The system is not a member of a sysplex.

CURRENT SYSTEM ID

An identifier that XCF assigns to a sysplex member. If the system is not a member of a sysplex, and has a JES2 subsystem, the system identifier is 0.

ACTIVE PFK SUFFIX

The 2-character suffix for the PFKTABxx parmlib member at the time the dump was written. This member contains the program function key (PFK) tables that have the installation definitions for PFKs. If no member was specified, NONE appears in this field.

ACTIVE CONSOLXX SUFFIX

The 2-character suffix for the CONSOLxx parmlib member at the time the dump was written. It contains console statements or other parameters that, in conjunction with the members MPFLSTxx and PFKTABxx, control the following:

SMCS STATUS

Indicates the status of the SMCS application. Possible values include:

ACTIVE

The SMCS application is connected to SecureWay Security Server and SMCS consoles are available for use.

NOT ACTIVE

SMCS is not active at this time. SMCS has failed and has completed termination cleanup processing.

INITIALIZING

SMCS is beginning to initialize.

WAITING FOR VTAM®

SMCS is attempting to communicate with VTAM, but VTAM is not available at this time.

WAITING FOR SMCS APPLID ACTIVATION

SMCS is communicating with SecureWay Security Server, but one of the following has occurred to the APPLID that SMCS is to use:

The APPLID has not been activated by SecureWay Security Server.
The APPLID was found to be not valid APPLID, but some other SecureWay Security Server resource.

The installation must ensure the separation of system logger logstream resources (separate catalogs and DASD). The logstream offload dataset naming convention must be included in the inclusion list as discussed in z/OS MVS Planning: Global Resource Serialization.

SHUTTING DOWN

SMCS has been requested to shut down. SMCS will cleanup and wait for the SMCS APPLID to become active.
