Installing TRANSFER
in an Existing
PATHWAY System
A TRANSFER system does not have to run in a separate PATHWAY system; it can be
integrated into an existing PATHWAY system (referred to as a mixed PATHWAY
system). The XCNFG, the XCOOL, and the XSTOP TACL macros, however, assume
that the TRANSFER system runs in a separate PATHWAY system. Therefore, these
macros cannot be used as they are if you want to integrate TRANSFER into an existing
PATHWAY environment.
Note When you integrate a TRANSFER system into an existing PATHWAY system, you complicate your
configuration management. Before you decide to do so, read to the end of this section.
The following section describes the tasks you perform to define, start, and stop a
TRANSFER system when it is not running as a separate PATHWAY system. What
you do is to mimic the functions of the XCNFG, XCOOL, and XSTOP macros.
Configuring TRANSFER
Initially in a Mixed
PATHWAY System
To configure the TRANSFER system for the first time, you follow all the steps for
installing a TRANSFER system described in Sections 4, 5, 6, and 7 of this manual,
including the execution of XCNFG. You actually build a standalone TRANSFER
system.
When you have a functioning TRANSFER system that is ready to run, you can begin
integration into the existing PATHWAY environment by following these steps:
1. Append the following commands to your CUSTCNFG file, which is explained in
Section 7 of this manual, “Customizing a TRANSFER System.”
INFO /OUT file/ TCP *, OBEYFORM
INFO /OUT file/ TERM *, OBEYFORM
INFO /OUT file/ PROGRAM *, OBEYFORM
INFO /OUT file/ SERVER *, OBEYFORM
Note file contains the PATHWAY definitions for all the TRANSFER components; make sure that no previous
file exists.
2. Run XCNFG again.
3. Enter:
1> PATHCOM /IN file/ $pm
where $pm is the PATHMON process name of your existing PATHWAY system.
This command defines all the necessary entries in the PATHWAY system.
4. Check your PATHWAY and PATHMON parameters, such as
MAXSERVERCLASSES and MAXTCPS, to make sure that they are sufficient for
running your existing PATHWAY system plus the new TRANSFER system.
You are now ready to start the TRANSFER system.
