Running in different modes

If you choose to log on to the OMEGAMON for CICS (3270) interface directly, you can do so in several different modes of operation.

These include VTAM®, ISPF, TSO, and dedicated modes. For information about how to install and start OMEGAMON for CICS (3270) in each mode, see the IBM Z OMEGAMON AI for CICS: Planning and Configuration Guide. The following table describes each operating mode and its requirements:

Table 1. The mode type and characteristics for OMEGAMON for CICS (3270) modes of operation
Mode	Characteristics
VTAM	VTAM mode enables you to run OMEGAMON for CICS (3270) sessions from a VTAM terminal without an intermediate online application, for example, TSO. You can set Auto Update mode so that the screen refreshes automatically. VTAM mode allows all VTAM terminal users to share a single copy of OMEGAMON for CICS (3270). TSF functions only in Auto Update mode (VTAM or dedicated). To activate Auto Update, select the Auto Update On option (F) on the Profile menu (fastpath P.F).
TSO and ISPF	The TSO address space communicates with the OMEGAMON for CICS (3270) address space through the VTM1 VTAM application. In this mode there is no auto screen refresh; the screen refreshes when you press the Enter key. TSO mode enables you to access OMEGAMON for CICS (3270) without logging off TSO. ISPF mode includes split-screen capability that you can swap between multiple OMEGAMON for CICS (3270) sessions, or between OMEGAMON for CICS (3270) and another ISPF application.
Dedicated	Dedicated mode offers high availability and does not require VTAM services. Dedicated mode uses EXCP to communicate with a terminal and refreshes the screen every few seconds. Dedicated mode allows OMEGAMON for CICS (3270) to provide realtime data even when VTAM is not available.
