I had problems to solve to combine old SMF records (0/IPL, 90(5A)/System
Status) when 4-char SMFID/SYSPLEX/SYSNAME are duplicated on different machines
as the CPUTYPE and serial number are not in most of the SMF records. I did ask
IBM to add those to the SMF header some time ago. I think through
I don't consider myself a "systems programmer" any longer... I assume the only
safe way to do this is with an IPL. I don't know if changing this dynamically
is an option. There will be no issue with SCRT. SYSNAME is in both the SMF 70
and SMF 89 records that SCRT processes. SCRT can handle chang
SMF89 record.)
Most of my licensees have 4-char SMFID=SYSNAME. I have a few customers where
they are different. As others have written some sites have found interesting
uses for the extra four characters in SYSNAME.
