5698-B12 Tiv Advanced Audit DFSMShsm high events SIISStore Into the Instruction Stream
TS003903912
We running ZOS 2.3
We running 5698-B12 Tiv Advanced Audit DFSMShsm 2.06.00
When we execute job UHSMA110 on sysplex system S2U1
we exceed the guard threshold for the percentage of SIIS events (Store Into the Instruction Stream) which caused cache Level 1 miss on the total of misses.
SIIS events are due to a code that does not respect the separation of data and instructions in the cache line.
This also happens on S2B1 system ( another sysplex ) when the analogous job runs.
We upload : smf records , joblog UHSMA110 , image from EPV monitor application .[Meno]
