If a z/OS system is attached to AWM, the master configuration file is read by a REXX procedure that must be located under the SYSEXEC or SYSPROC allocation. The name of this REXX procedure is TAUZCAPP.
If you attache a new remote system to the Tree view, the new system entry receives the remote system name returned from the master configuration file. The called REXX procedure updates all AWM model entries which are listed in the master configuration file. At this time a specific AWM model is not loaded.
This REXX procedure is called each time you perform an action for the first time during an Eclipse session that requires a link to the remote system. The following checks are performed when the REXX procedure is called:
Could the REXX procedure be located on the remote system. If not, the action is cancelled, producing an error message.
The REXX procedure checks the consistency of the master configuration file. If any error occurs it is communicated in an error dialog. Warnings are written into the Eclipse .log file.
The data set name of the master configuration file is specified in TAUZCAPP respectively TAULAPPL. The REXX procedure used with the server installation (REXX TAUZCAPP with a MFA Server installation, REXX TAULAPPL with a RSED installation) has to be adapted after the MFA server installation, otherwise the mainframe server is not able to find the master configuration file. See Mainframe Access Installation Guide for more information.
