Introduction

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

Environment

The UCTL Server runs as z/OS UNIX System Services (USS) background process started by the Universal Broker. The address space name is UCTSRV. Its user identifier is inherited from the Broker address space.

As with all components managed by the Universal Broker, UCTL Server inherits the message language from the Universal Broker. All messages generated by the Universal Control Server are sent to Universal Broker for processing.

User Identification

UCTL Server can operate with user security active or inactive, based on the USER_SECURITY configuration option.

With user security active, the UCTL Server requires the UCTL Manager to supply a valid z/OS user ID and a password. The user profile must have a properly defined OMVS segment.
With user security inactive, the UCTL Server does not require the UCTL Manager to supply a valid user ID. Essentially, any operation that the UCTL Server is capable of can be requested by any UCTL Manager.
