The first couple of PTFs in the HIPER group are enough scare the wits out of you, so we just went with them. The important thing is to get them on your systems as soon as possible. You need to install the whole HIPER group.
There was a time, a long, long time ago, when the CUME PTF pack sufficed when it came to keeping the system up to snuff. The CUME hasn’t contained all of the patches necessary to keep your systems running smoothly for quite a while, though. We need to pay attention to our Group PTFs and apply them as frequently as we can.
Here is the list of HIPERs:
V7R3 MF63501 05/30/17 MA46327 5770999 1000 During normal operations a partition terminates with a SRCB6000103. CORRECTION FOR APAR MA46327 : ----------------------------- Licensed Internal Code tries to allocate additional storage in a critical window, where it can cause an exception. The storage is now obtained outside of the window. This problem is very unpredictable; the fix should be applied at the earliest convenience. MF63634 05/30/17 MA46392 5770999 1000 SLB (Segment Lookaside Buffer) entries are used to resolve Process Local Addresses (PLA) for Teraspace and PASE (Portable Application Solution Environment) applications. Improper serialization allows the structure that tracks SLB entries to be updated while being read, leading to duplicate entries. Once the duplicates are encountered, the hardware diagnostics take an exception. If this exception happens frequently enough, the system may decide the processor involved is failing, and flag the processor for deconfiguration on the next full system IPL. The hardware detection would be shown as a Platform Event Log (PEL) with the following SRCs: src word 1: srcB113E504 B113E504 src word 8: srcC8E90022 C8E90022 LS_SLB_MULTIHIT_ERR CORRECTION FOR APAR MA46392 : ----------------------------- LIC is changed to avoid adding duplicate entries to the SLB. V7R2 MF63500 05/30/17 MA46327 5770999 1000 Same as MF63501 for V7R3 above MF63632 05/30/17 MA46392 5770999 1000 Same as MF63634 for V7R3 above V7R1 MF63499 05/30/17 MA46327 5770999 1000 Same as MF63501 for V7R3 above MF63633 05/30/17 MA46392 5770999 1000 Same as MF63634 for V7R3 above
