Introduction to the ILOGMGR
Figure 1-2 shows how the ILOGMGR and the TLOGMGR interact to establish a
session. Upon activation, the ILOGMGR examines its control file and finds a
TLOGMGR whose SNA LU name is tn1. The ILOGMGR then sends a BIND request to
the appropriate TLOGMGR (tn1).
SNAX/APN receives the BIND request and creates a remote LU object to represent the
ILOGMGR (ibm1), thus establishing an LU-LU session (type 6.2) between the
ILOGMGR and the TLOGMGR.
When examining its control file, the ILOGMGR also finds the names of Tandem
applications; for example, tcl1. In this case, the ILOGMGR (ibm1) opens the VTAM
access method control block (ACB) named tcl1. If tcl1 is defined in the VTAM list
(VTAMLST), the ILOGMGR successfully opens the access method control block.
See Section 3, “Configuring for the ILOGMGR,” for detailed information about
configuring the control file.
