Introduction to the ILOGMGR
Figure 1-5 shows the ILOGMGR forwarding a Program Start Request
(PROGRAM_START_REQ) to the TLOGMGR. The TLOGMGR automatically
configures a remote LU object to represent the 3270 device (lua1).
At this time, the LU representing the remote device is started, and the requested
application (tcl1) sends a BIND to the 3270 device (lua1).
Note. Program Start Requests can also be generated by the TLOGMGR. You do this by using
the SNAX Application Logical Unit (SNALU) feature of SNAX/APN with mode of operation SLU
Acquire. See the SNAX/APN Application Programming Manual for further details.
