UTM-SM2 subsystem

The SM2 event monitor can store performance values for active UTM applications in the SM2 measurement file and output them to the screen. A prerequisite is that the UTM-SM2 component is installed. UTM-SM2 is included in BS2000-GA (basic configuration). UTM-SM2 is loaded as an independent subsystem of BS2000.

Components

UTM-SM2 contains the following libraries and files:

Name	Contents
SYSLNK.UTM-SM2.nnn SKMLNK.UTM-SM2.nnn	Load library for servers with /390 architecture Load library for servers with x86 architecture
SYSSSC.UTM-SM2.nnn	SSD object for BS2000 operating system
SYSREP.UTM-SM2.nnn	REP file

The identifier nnn stands for the UTM-SM2 version:

nnn=190 for UTM-SM2 V19.0 on BS2000 OSD/BC V10.0
nnn=200 for UTM-SM2 V20.0 on BS2000 OSD/BC V11.0

When installation is performed using IMON, the REP file is generated from the supplied fileSYSRMS.UTM-SM2.nnn.

Entries in the subsystem catalog

With the SSD object, the system administrator can create an entry for the UTM-SM2 subsystem in the subsystem catalog of the BS2000 during operation.

With the standard installation, IMON automatically creates the entry in the subsystem catalog for UTM-SM2.

The following default values apply in the SSD objects SYSSSC.UTM-SM2.nnn and SPMSSC.UTM-SM2.nnn:

• Load time:
  UTM-SM2 must be explicitly loaded with the command START-SUBSYSTEM.

• Installation user ID:
  *DEFAULT-USERID

• Load library:
  SYSLNK.UTM-SM2.nnn on servers with /390 architecture
  SKMLNK.UTM-SM2.nnn on servers with x86 architecture

• REP file: SYSREP.UTM-SM2.nnn

The UTM-SM2 subsystem default settings can be changed by the system administrator. For changes to be permanent, they should be made using IMON resources. For details, refer to the "IMON" user manual.

The default value for the load time must not be changed by the system administrator.

Loading the UTM-SM2 subsystem

UTM-SM2 can be loaded via a system administrator command as well as via openUTM.

• Loading via a command:

  /START-SUBSYSTEM SUBSYSTEM-NAME=UTM-SM2

• Loading via openUTM (there are two possibilities here):

  • UTM-SM2 is automatically loaded at the start of the application if the application is generated with MAX SM2=ON.

  • UTM-SM2 is loaded implicitly by the administration when the data is supplied if the application is generated with MAX SM2=OFF or MAX SM2=ON.

Unloading UTM-SM2

UTM-SM2 is unloaded with the command:

/STOP-SUBSYSTEM SUBSYSTEM-NAME=UTM-SM2
