Configuring an Invokable TP Using snaptpinstall

File Format for snaptpinstall

If you use NON-QUEUED, more than one copy of the TP can be running at a time. If the TP writes to files on the Windows computer, you need to ensure that different copies of the TP do not overwrite each other's files. To do this, use one of the following methods:

•Ensure that the TP appends data to an existing file instead of creating the file (so that all copies of the TP append data to the same file)

•Design the TP to generate file names at run-time, based on the process ID with which the TP is running (so that each copy of the TP writes to a different file).

This line is optional. If it is not included, or if an invalid value is specified, the default is QUEUED.

TIMEOUT

The maximum length of time, in seconds, that a Receive_Allocate call issued by the TP should block if there is no incoming Allocate request pending. If no incoming Allocate is received in this time, the call fails with a return code indicating “State check - Allocate not pending.”

A timeout value of 0 indicates that the call always fails unless an incoming Allocate is already pending when the call is issued. A timeout value of −1 indicates that the call waits indefinitely for an incoming Allocate and does not time out.

This line is optional. If it is not included, or if an invalid value (a non-numeric value) is specified, the default is −1 (infinite).

Do not specify this parameter if the TYPE parameter is set to NON-QUEUED. SNAplus2 uses a timeout value of 0 for nonqueued TPs, because the TP is always started in response to an incoming Allocate and so there is always one pending.

For UNIX USERID

Specify the user ID that SNAplus2 uses to start the TP. The TP is started in the home directory associated with this user ID. This home directory is also the default path for trace files and any other files accessed by the
