Maintaining Statistics HDBs

Statistics and Performance HDBs are maintained in the same way. You can alter any of the HDB characteristics, such as container data set name and allocation size.

Select option 7 Maintenance from the HDB menu to maintain your HDB environment.

For Statistics HDBs, you can also change the types of statistics data collected. Select Select to specify Statistics Reports to review or alter the type of statistics collected.

In the following example, we have activated collection for Transaction Manager statistics.

Note that either activating new reports, or deactivating reports already collecting data does not change the data already collected. All the existing data can still be reported, regardless of whether collection is still active or not.
