Have you ever wondered why CA Support recommends performing GLOBAL RESOLVES twice a year? This Knowledge Document provides an explanation.
A GLOBAL RESOLVE of your Production Schedules to Base Calendars is recommended twice a year to help ensure seamless scheduling of the CA 7 controlled production workload, and for other purposes such as forecasting. CA 7 is limited to 12 months of resolved calendar-oriented processing schedules at a time. Because of this fact, when you perform your Global Resolve between January 1st and June 30th, CA 7 will resolve 12 months of schedules - January thru December of current year. If you DO NOT perform another global resolve between July 1st and December 31st, all calendars would expire on December 31st after midnight. Performing Global Resolves twice a year will provide schedule overlapping and keep your schedules from expiring at the end of the year.
When you perform this 2nd Global Resolve between July and December, this will resolve 12 months again with the time frame representing July of current year through June of the following year. Not only will this keep your schedules from expiring, this will also be necessary to allow forecasting your workload into the following year.
You can create your Base Calendars in advance. Since CA 7 is limited to only 12 months of resolved processing schedules at a time, you will still need to do your Global Resolves twice a year to build them prior to use, as explained above.
The command to issue your GLOBAL RESOLVE is as follows:
You can use the LSCHD command to determine when your schedules will expire. Key in the following to view schedules expiring after June 30th:
LSCHD,DSNBR=SJ*,ST=JUL (or ST=JAN or ST=EXP for already expired)
(Listed from above command as either JANUARY or JULY SCHEDULE)
More information on this subject can be found in the Command Reference Guide and Systems Programming Guide.
