Question How will Torch behave after upgrading to CP15? Answer There was a change in the ALOG format from CP14 to CP15 that does have an impact on Torch. We've tested the Torch run across ALOG cycles that span the upgrade from CP14 to CP15. Torch will not successfully run after the upgrade unless the CP14 cycles are removed, and also the bridge/spare cycle created at the time of the upgrade. That is, as long as it starts with a CP14 cycle, it will fail when it reaches a non-CP14 cycle. You can use the TORCH.CYCLE-INFO utility to see cycles from before and after the upgrade. For instance, these are some sample cycles: CYCLE-INFO 4R7EQ1 (140807 1119:50) 2014-08-08 10:06:51 CDT Enter file name (or just return for ASCII Log File): -------------------------------------------------- rel abs Audit Trail # of fcycle fcycle creation date/time tracks -------------------------------------------------- 0 60 23:16:08 on Aug 3, 2014 20000 -1 59 12:29:52 on Aug 3, 2014 20000 -2 58 12:29:52 on Aug 3, 2014 1 <-- date is wrong, we will update. -3 57 12:14:39 on Aug 3, 2014 25000 -4 56 12:14:38 on Aug 3, 2014 25000 -------------------------------------------------- In this case, cycles 56 and 57 were CP14 cycles. Cycle 58 is the �bridge� cycle. It is not completely empty as the OS writes a block of data (with a specific pattern) when it initially assigns it to make sure it is writable, but there are no records for Torch to process. Cycles 59 and 60 are CP15 cycles. You can force Torch start processing at a specific cycle, and force the CP15 cycles to be merged until the CP14 cycles have aged off the system. If you only want to run the Torch process once per day, you will need to remove the CP14 and bridge cycles after Torch runs once. That is: Day 1: Upgrade to CP15. Day 2: Torch runs at about 6:00 am. CP14 cycles will be merged; processing will stop at the bridge cycle. Day 2: Back up and remove CP14 cycles, and also the bridge cycle. Day 3: Torch runs at about 6:00 am. All CP15 cycles from Day 1 and Day 2 will be processed and merged. Please let us know if more detail is required. Symptoms Torch processing for ALOG cycles stops at new cycles produced by CP15.
