Is it documented which Db2 IFCID field name is being used to populate the columns in the Sysview Performance Management
Option for Db2 for z/OS (IDB2) archive database?
The Archive Tables section in the Sysview for Db2 documentation list the Db2 column names with the corresponding common IQL field names.
One can then look up the definitions of the IQL field names in the same guide, in the "Common Fields/Records and Fields" section,
to determine the corresponding IBM IFCID field names.
