IBM has introduced a new SMF type 100 subtype 5 records which aggregate the QWAC and QWAX transaction level accounting statistics and produces an interval record. Statistics include CPU times on CP and specialty engines and various wait times and counts. The new DB2 Aggregated Accounting Stats (DB2DAS) file enables users to report easily on transaction statistics with system level statistics for the same interval. In addition, this file provides the user the ability to analyze transaction-based performance and usage information without processing high volume transaction level data.
