A DB2 region can access multiple Netezza appliances resulting in a separate data section in the record with the metrics from each appliance. The original support for IDAA, product change DB26816, only supported the first Netezza data section in the SMF type 100 subtype 1 record. The original DB2DSD file IDAA data elements are being obsoleted and information about Netezza appliances is provided with a new DB2 System IDAA Activity (DB2DSI) file.
The IDAA/NOIDAA keyword that is used on the OPTION statement on sharedprefix.MICS.GENLIB(DB2GENIN) controls the activation or deactivation of this file.
IDAA-related metrics that are read from the SMF 101 transaction records which populate the DB2DSU and DB2DSP files are not affected by this change.
