Universal Control Manager for zOS

Universal Control Manager for zOS

Introduction

This Universal Control (UCTL) Manager information is specific to the z/OS operating system.

UCTL Manager for z/OS executes as a batch job.

Control Requests

UCTL Manager for z/OS supports all three Universal Control control requests:

  1. Start (START_CMD option)

  2. Stop (STOP_CMD option)

  3. Refresh (REFRESH_CMD option)

JCL Procedure

The following figure identifies the UCTL Manager for z/OS JCL procedure (UCTLPRC, located in the SUNVSAMP library) that is provided to simplify the execution JCL and future maintenance.

Description

STEPLIB

DSORG=PO,
RECFM=U

Input

Load library containing the program being executed.

UNVNLS

DSORG=PO,
RECFM=(F, FB, V, VB)

Input

UCTL national language support library. Contains message catalogs and code page translation tables.

UNVTRACE

DSORG=PS,
RECFM=(F, FB, V, VB)

Output

UCTL trace output.

SYSPRINT

DSORG=PS,
RECFM=(F, FB, V, VB)

Output

stdout file for the UCTL program. UCTL does not write any messages to SYSPRINT.

SYSOUT *

DSORG=PS,
RECFM=(F, FB, V, VB)

Output

stderr file for the UCTL program. UCTL writes its messages to SYSOUT.

* The C runtime library determines the default DCB attributes. Refer to the IBM manual OS/390 C/C++ Programming Guide for details on default DCB attributes for stream I/O

JCL

The following figure illustrates the UCTL Manager for z/OS JCL using the UCTLPRC JCL procedure, above.

//jobname JOB CLASS=A,MSGCLASS=X //STEP1 EXEC UCTLPRC //SYSIN DD * -stop 10312932 -host dallas -userid joe -pwd akkSdiq /*

Job step STEP1 executes UCTLPRC.

The configuration options are specified on the SYSIN DD.

Configuration

Configuration consists of:

  • Setting default options and preferences for all executions of UCTL Manager.

  • Setting options and preferences for a single execution of UCTL Manager.

Configuration Sources

Configuration options are read from the following sources:

  1. PARM keyword

  2. SYSIN ddname

  3. Command file ddname

  4. Configuration file

The order of precedence is the same as the list above; command line being the highest, and configuration file being the lowest. That is, options specified via a PARM keyword override options specified via a SYSIN ddname, and so on.

Detailed information on these methods of configuration can be found in Configuration Management.

Configuration File

The UCTL Manager configuration file is provided to the manager by the local Universal Broker with which it registers. The UCTL Manager configuration file is located in the UCTCFG00 member of the PDSE allocated to the UNVCONF ddname in the Universal Broker started task.

The configuration file, provided by the local Universal Broker, provides the simplest method of specifying configuration options whose values will not change with each command invocation. These default values are used if the options are not read from one or more other sources.

Some options only can be specified in the configuration file; they have no corresponding command line equivalent. Other options cannot be specified in the configuration file; they must be specified via one or more other sources for a single execution of UCTL Manager.

Note

For any changes to the UCTL Manager configuration file to become active, a Universal Broker refresh is required, or the Universal Broker started task must be restarted.
