Question:

Seeing an increase of acct trace records in SMF data being collected due to package tracing after new install of INSIGHT. In IDDCPRMS tracing parms ACCTTRACE=8 is set. dis trace command shows them being collected in its own buffer. Does this buffer get externalized to SMF and if so, what's the trigger and can it be turn off?

Answer:

The IFI parameter controls the destination of the Unicenter CA-Insight  traces. If IFI=YES, the destination is usually OP1 for Online Perfomance monitor buffer number 1. If other performance monitoring programs using the  IFI are active, Unicenter CA-Insight will be assigned the next destination number in sequence, so you could see destination OP2 or OP3.                                                     Some trace data can be externalized to SMF and other can't. Technically, READA (tracing of events in DB2) data can and READS data cannot be written to SMF (traces reflecting real-time snapshot of subsystem and thread information).                                 However, to get READA data written to SMF, you need to start a trace with the appropriate trace classes and IFCIDs with DEST(SMF).                           

The monitor(Insight) does not write data to SMF nor start traces for destination of SMF.  Insight does provide support for a SAVEIFI file which will cause the DC to capture and write out raw trace records to the linear dataset, which can be unloaded to SMF formatted file or used directly as input to the batch report writer.
