SS Statistics Records
The SS statistics records contain information about SELECT STATISTICS processing. One SS record is written for each SELECT STATISTICS command that executes. The SS record includes information such as the index that IBM® Connect:Direct® uses to search the files and the number of requests issued to the keyed and entry-sequenced clusters. The record also includes the number of records examined and rejected.
Use the SELECT STATISTICS command with the TYPE parameter to view the SS record.
Using selection criteria with the SELECT STATISTICS request improves the performance by efficiently locating the requested records. For example, you can include the ID of the user that issued the SELECT STATISTICS command or the approximate time the request was issued, using the STARTT, STOPT, and USER parameters. The following figure shows an example using this selection criteria.
