COMM (Communicate with MUF) › COMM CLRPXX (Clear Statistics and Diagnostics Area (PXX))

COMM CLRPXX (Clear Statistics and Diagnostics Area (PXX))

The COMM CLRPXX option clears the Statistics and Diagnostics Area (PXX) of all data. This option has the same effect as disabling and enabling the MUF. That is, CA Datacom/DB begins to write data to logical block one, and all data previously in the Statistics and Diagnostics Area (PXX) is lost.

Note: Summary statistics are maintained in the MUF and are not cleared nor reset in memory.

The COMM CLRPXX function communicates with one MUF. Be aware of the following:

• Ensure that DBUTLTY is communicating with the desired MUF by executing DBUTLTY with the same System Identifier module (DBSIDPR) that is being used by the MUF, and
• Ensure proper load library concatenation by keeping the System Identifier modules (DBSIDPR) in separate load libraries.

If the z/OS Cross-System Coupling Facility (XCF) is being used, ensure that the TOGROUP DBSIDPR parameter is correctly defined. For more information about XCF, see the CA Datacom/DB Database and System Administration Guide.

When using a console command, these steps are unnecessary.
