When the BIS Request Handler passes a request to a service program, page rendering is suspended while the program performs the required processing. The service timeout value sets an upper bound on the amount of time that page rendering will be suspended.
The default service timeout is 30 seconds. This value can be changed in the following ways:
BIS_SERVICE_TIMEOUT=30This environment variable sets the timeout to 30 seconds. See Setting Environment Variables for information about setting and modifying environment variables on Windows, and Service Engine Configuration for information on configuring BIS on UNIX.
Of the above, the BIS_SERVICE_TIMEOUT variable and ServiceTimeout option keyword have the lowest priority and are overridden by either SessionParms tag or the B_SetServiceTimeout call.
