Migrating TPs to LU 6.2 API/XL Peer-to-Peer
Customers migrating to the peer-to-peer version (the Release 4.0
version) of LU 6.2 API/XL from LU 6.2 API/V or from an earlier
version of LU 6.2 API/XL might have to change their transaction
programs. Transaction programs will require modification if they
perform either of the following functions:
1. Issue APPCCONTROL commands programmatically.
2. Call the MCGetAllocate intrinsic to receive allocate requests
from remote TPs.
TPs that issue APPCCONTROL commands must be changed, because
APPCCONTROL commands will be interpreted by a system UDC
instead of by the MPE command interpreter. The MPE COMMAND
intrinsic (for issuing MPE commands programmatically) can be
replaced with the MPE HPCICOMMAND intrinsic (for executing
UDCs programmatically). Or, the programmatic calls to
APPCCONTROL commands can be replaced with calls to the new
control operator intrinsics, which will perform the same
functions as APPCCONTROL commands. The control operator intrinsics
will be included in the peer-to-peer version of LU 6.2 API/XL.
TPs that call the MCGetAllocate intrinsic must be changed, because
the LocalTPName parameter of the MCGetAllocate intrinsic will be
an input parameter in the peer-to-peer version of LU 6.2 API/XL.
(It was an output parameter in previous versions of the product.)
The April 1992 edition (the Release 4.0 edition) of the LU 6.2 API
Application Programmer's Reference Manual (30294-61000) will explain
how to migrate transaction programs to the peer-to-peer version of
LU 6.2 API/XL. Instructions will be in appendix F of that manual.
