Key concepts

Common REST API (CRA)

CRA enables you to retrieve data collected by BMC mainframe monitoring products.

BMC Configuration Component for z/OS (LGC)

The LGC technology separates product or solution installation from configuration. Through its online interface, LGC simplifies configuration and deployment by setting default option values for you.

BMC Execution Component for z/OS (DBC)

DBC provides a persistent z/OS subsystem address space into which BMC products can dynamically initialize their own product services.

The following components also require the DBC subsystem:

• The Data Collector for System and SQL Performance products
• BMC AMI Command Center for Db2 (also called the GUD component)
• BMC Subsystem Optimizer for zEnterprise
• LGC and NGL infrastructure components

Next Generation Logger (NGL)

NGL is a logging facility that logs and retrieves data based on application-defined keys and a time span. NGL runs as a service within the DBC subsystem and relies on the Registry Component of RTCS to permanently store information used to manage the logged application data.

Runtime Component System (RTCS)

RTCS runs as a started task and provides programming services to various BMC mainframe products. RTCS is designed for continuous operation and seldom, if ever, needs to be stopped.

User Interface Middleware (UIM) 

UIM provides a client/server environment that facilitates communication between clients and the mainframe computer. UIM also provides a framework for web-based consoles.

Cross-System Image Manager (XIM)

XIM provides sysplex performance improvements by enabling the distribution and management of discrete units of work (UOW) across one or more MVS systems.
