RSC/MP Installation and Configuration Guide

Installation Troubleshooting Step 5. Run the Workstation RSC/MP Test Program
If no process is found, start the process before proceeding:
4>RUN $SYSTEM.ZRSCHOST.TDDSVR /NAME $TDD,NOWAIT/INTERPROCESS
If there is more than one RSC/MP ISV on your system, be sure that you are using
the correct one. Use the VOLUME command to locate to the ISV for the version of
RSC/MP that you are going to use.
3. Ensure that a TDP process is running. The installation process moves the TDP
object code to $SYSTEM.SYSTEM. Enter the following command at the TACL
prompt:
5> STATUS *,PROG $SYSTEM.SYSTEM.TDP
There must be at least one TDP process running on the NonStop system; there
can be more. If the TDP process with a configuration you need is not running, start
the TDP process.
Step 5. Run the Workstation RSC/MP Test Program
The RSC/MP test program should immediately report message traffic between the
workstation and NonStop host. If the test fails, you receive an appropriate error
message. Record the message number and see the Remote Server Call (RSC/MP)
Messages Manual to investigate its cause and remedy.
Step 6. Interpret the Workstation and Host Error Messages
The RSC/MP product provides error messages on both the workstation and the
NonStop host. These error messages provide the first opportunities to resolve
problems with RSC/MP connectivity.
The error messages that the RSC/MP test program displays can help you to determine
if the problem is on the workstation or the NonStop host. If the problem is on the host,
TDP error messages help to identify a solution.
To interpret errors, it is necessary to understand the conditions required for
establishi ng a successful RSC/MP environment:
1. RSC/MP can run on the workstation. In the Microsoft Windows environment,
RSC/MP must communicate with any necessary DLL libraries needed to support
its API calls.
2. RSC/MP can find and open the correct RSC.INI file.
3. RSC/MP can successfully use the communications subsystem on the workstation.
4. A communication channel (for example, a network) exists between the
workstation and the host.
5. The communications subsystem on the NonStop host acknowledges or receives
messages from the workstation.
