WLX Audit for Db2 z/OS works solely with IBM Technology. It gathers all static & dynamic SQLs from EDM & DSC Caches by STC to OPx and efficiently uses IFCIDs 23, 24, 25, 62, 90, 91, 140, 141,142, 143, 144, 219, 220, 316, 318, 400, 401
There are hundreds of IFCIDs that you can start and use for Db2 z/OS Audit or performance monitoring. Some come very cheaply like the 316, 317, 401 some are very CPU expensive like the 58 (SQL Full Trace). WorkLoadExpert (WLX) does not use the following IFCIDs for this very reason.

WLX Audit for Db2 z/OS use the Following IFCIDS
WorkLoadExpert (WLX) does not use
the following IFCIDs
|IFCIDs 23, 24, 25, 219, 220||Utilities||IFCID 58||SQL Trace. Very expensive indeed!|
|IFCIDS 62||DDL||IFCID 63 IFCID 350||SQL statement text Output by every PREPARE, BIND/REBIND and also very expensive|
|IFCIDS 141||DCL||IFCID 97||Drop of objects is covered by the 62 DDL IFCID|
|IFCIDS 144, 316, 318, 400, 401||DML||IFCID 107||For every table open and close is very expensive and again can be easily got with the data already in the IFCIDs 316, 317 and 401|
|IFCIDS 90, 91, 140, 142, 143||IFCID 145||Audit SQL text. Is Available with the IFCIDs 316, 317, 401 and so this is not required|
|IFCID 247||Host variables. Is very expensive and not required for Audit|

From our experience with the banking industry we established an effective process where our WLX Audit replaces the homegrown customer solution.
|IFCID 361||Audit Administrative Authorities. Unless you are running with Audit Policy SYSADMIN or DBADMIN this IFCID outputs for *every* SELECT, INSERT etc. this is very high CPU and just dangerous in production. The data within can be captured using other means|
