Managing targets and target contexts

A target is a system or subsystem that is being monitored by one or more MainView products, such as a system image, IMS or DB2 subsystem, or CICS region.

A target context is a single target and product combination.

When a product is running in full-screen mode, the target ID is displayed in the upper-right corner of the screen in the TGT field. When a product is running in windows mode, the target context is displayed on the window information line. In windows mode, you also can view data from several targets at once and the context that is displayed on the window information line is called an SSI context. See Managing SSI contexts for more information about defining and displaying SSI contexts.

Target IDs are defined in the BBI-SS PAS in BBPARM member BBIJNT00 for applications that run in full-screen mode. Target contexts are defined with the Plex Manager TGTDEF and TGTDEFD views for applications that run in windows mode.


For MainView for CICS, new targets can be dynamically defined by using the Plex Manager Add Target Definition dialog from the TGTDEF view. The target definitions are saved in BBPARM member BBMTXP nn, where nn is a number from 00 to 99. The definitions are appended to an in-memory list of target entries that is produced from member BBIJNT00. Existing targets cannot be modified with the TGTDEF dialog.


The information in this section applies to specific MainView products as described in each topic.

This section explains how to perform the following tasks:
