On startup, the UFINIT control member is processed and the UFHIST file is rebuilt to contain the new information. For files that were defined previously, the last modified date that was contained in the UFHIST file is retained.
Once initialization is complete, the files that are specified in the UFHIST file control member are checked to see if they have been modified, if so, the command associated with the modified file is issued to the specified CA scheduling system. Once all the files are checked, a wait for the interval is issued and then the file check is repeated. This continues until termination or a refresh is requested. Termination causes an orderly shutdown. Refresh reads the UFINIT file and rebuilds the UFHIST file. A refresh can be requested in real time.
The UFINIT file control member is read at startup, updates the UFHIST file, and then begins monitoring. If errors are found in the UFINIT file, a WTO will be issued showing the error and the line number in the control member where it occurred.
