IBM SC34-4499-03 manual Starting an MVS build server

v-ssends log ®le messages to the screen.The build server generates a log ®le called teamcbld.log. Build server log messages can be routed to the screen using the -sparameter.

v-nwrites ®les:

±writes the changed environment variables to a ®le calledtcbldenv.lst instead of setting them in program's environment. The format of the ®le isvariable=value.

±writes the list of input ®les to a ®le calledtcbldin.lst. One ®le per line, format is pathName type.

±writes the list of output ®les to a ®le calledtcbldout.lst. One ®le per line, format is pathName type.

You can also set the -sand -nbuild options using the TC_BUILDOPTS

environment variable.

Two environment variables that directly affect build performance are:

vTC_BUILDMINWAIT - Minimum amount of time to wait (in seconds) between queries for new jobs. Default setting is 5, minimum setting is 3.

vTC_BUILDMAXWAIT - Maximum amount of time to wait (in seconds) between queries for new jobs. Default setting is 15, maximum setting is 300.

The command teamcbld will check the family for work to do every TC_BUILDMINWAIT. If it is not busy it will slow down to the TC_BUILDMAXWAIT time. The build administrator can adjust these variables to tune the frequency that the build server will check the family.

Starting an MVS build server

The MVS build server is a special client to the family server. It uses a user ID that must be de®ned to the family server. Depending on the authentication level in effect, a host list entry must be created for the user, and, if password authentication is required, the -l parameter must be used to specify the password when starting the build server.

The user ID used by the build server is the TSO user ID under which the build job is started. The user ID must always be in uppercase and must be created in uppercase on the family server. The user ID is not determined by the TC_USER environment variable.

You can start the MVS build server program TEAMCBLD, in Batch or under TSO. The RUNPGM JCL executes the MVS build server in batch. The RUNPGMT JCL executes the MVS build server under a TSO environment.

The following summarizes the actions to run the build server on MVS:

Modify the RUNPGM JCL for your installation.

Modify the environment variable dataset as needed. Two environment variables that directly affect build performance are:
