Chapter 4 Initializing and Testing the Native Execution Environment : Overview

Overview
The Native Execution Environment is a TIBCO Object Service Broker component that enables multiple users concurrent online access to a Data Object Broker and its attached external database servers. It can be executed as a batch job or as a started task.
The single most important benefit of the Native Execution Environment is reduced overhead, thus accommodating a large number of user sessions in a single address space.
Facilities That Require a Native Execution Environment
The Native Execution Environment component is required for the following facilities:
NOTE: The Service Gateway for CICS component can be used as an alternative to connect Eclipse UI sessions.
Events During Native Execution Environment Initialization
During Native Execution Environment initialization, the following events take place:
The Execution Environment establishes environments for Cross Memory Services (XMS), VTAM, and TCP/IP communications. For VTAM, it opens an ACB with the name specified by the EENAME initialization parameter.
An Execution Environment is created that establishes communication with the Data Object Broker specified by the TDS parameter defined in the Execution Environment initialization parameters.
Communications from the user to the Native Execution Environment and from the Native Execution Environment to the Data Object Broker are established using the most efficient communication method possible (Cross Memory Services or TPC/IP).
Logging In to the Native Execution Environment
When this initialization is complete, users can log in to the Native Execution Environment using the VTAM LOGON command. For details, see Log In to a Native Execution Environment.
IMS TM users connect to a Native Execution Environment when they invoke the TIBCO Object Service Broker IMS TM command to log in to TIBCO Object Service Broker.
