OMEGAMON for IMS modes of operation

When you configure OMEGAMON® for IMS, you are asked to select and customize an operating mode.

Available operating modes are as follows:

VTAM® mode
TSO/ISPF mode
Dedicated mode

The following table describes each operating mode and its requirements.

Table 1. Characteristics and requirements for OMEGAMON for IMS modes of operation
Mode	Characteristics	Configuration requirements
VTAM	Use VTAM mode to run OMEGAMON for IMS sessions from a VTAM terminal without an intermediate online application, such as TSO. You can set automatic update mode so that the screen refreshes automatically. VTAM mode allows all VTAM terminal users to share a single copy of OMEGAMON for IMS.	Define a VTAM applid for OBVTAM.
TSO and ISPF	The TSO address space communicates with the OMEGAMON for IMS address space by using a VTAM application, VTM1. In this mode, there is no auto screen refresh; the screen refreshes when you press the Enter key. Use TSO mode to access OMEGAMON for IMS without logging off TSO. ISPF mode includes split-screen capability that you can swap between multiple OMEGAMON for IMS sessions, or between OMEGAMON for IMS and another ISPF application.	Define a VTAM applid for OBVTAM. Requires an active OBVTAM application. Define a set of virtual terminals to VTAM. You can define up to 99 virtual terminals in the virtual terminal pool (VTPOOL).
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 IMS to provide real-time data even when VTAM is not available.	Availability of a locally attached non-SNA terminal.
