Specify SQL data collection parameters for your DB2 environment.

• Explain SQL
  Requests that information regarding DB2 access path selection be obtained from DB2 SQL statements by issuing the EXPLAIN command and externalizing the data.

  • Selected
    Specifies that DB2 EXPLAIN data is collected for all statements seen. The call for Explain data is made while the address space is being measured. If YES is specified then Use DB2 Catalog for EXPLAIN must also be YES.

  • Unselected
    Specifies that no DB2 EXPLAIN data is gathered.
    Default: Unselected

• DB2 Requestor Location
  Specifies whether the requesting location name for a SQL statement is collected as part of the key.
  Default: Unselected

• DB2 Operator ID
  Specifies whether the operator ID is collected and used as part of the key.
  Default: Unselected

• Get SQL from Catalog
  Use this option to determine whether CA MAT extracts the plan or package statements from the DB2 catalog or extracts them directly from DB2 control blocks when monitoring a DB2 application. Suppressing the collection of the SQL statements from the DB2 catalog can result in the incorrect statement being identified during the sample process.

  • Selected
    Indicates that SQL data is collected for each plan or package sampled or harvested from the DB2 catalog. This value is the default and is recommended.

  • Unselected
    Indicates that the SQL statement is not collected from the DB2 catalog.

  If Explain SQL is selected then the Use DB2 Catalog for EXPLAIN is forced to YES (in case, the value was NO previously) because the DB2 Catalog must be accessed to collect EXPLAIN data.

• DB2 Correlation ID
  Specifies whether the correlation ID is collected and used as part of the key.
  Default: Unselected

• DB2 Thread Address
  Specifies whether the thread address is used as part of the key.
  Default: Unselected
