Defining a Statistics HDB allows you to collect (load) and report historical CICS® statistics and server statistics data and CICS Transaction Gateway statistics data. The definition alone does not cause any action by CICS PA.

Specify APPLID to ensure that only data for this CICS system is loaded into the HDB. At Load time, CICS PA will generate JCL that includes this APPLID in the command deck and DD statements for this system's SMF Files.
qualifier.CPA_statid
Qualifier
is mandatory if Explorer is selected, and optional otherwise. If Qualifier
and Explorer are both entered then details of this HDB will be included
in the manifest for the CICS PA plug-in the
next time it is rebuilt for this qualifier.If the HDB container data sets are no longer required after their data has been exported to DB2, you can specify a retention period of 0 in any of the HDB periods to make the HDB data sets expire immediately.
Container data sets and DB2 data are deleted by HDB Housekeeping after they have passed their expiry date. If you do not specify a retention period, the corresponding HDB data sets or DB2 data will never expire.
Use HDB Maintenance to check container data set status or to alter the HDB or DB2 retention period.
The format of the data set name is
DSN-prefix.HDB-name.Dyyddd.Thhmmss.HDB
where the DSN prefix is the data set name high level qualifier.
Specify allocation settings that satisfy your installation requirements. The size of container data sets is not critical. Typically you would specify a size that accommodates a single load request. For example, if you load data into the HDB daily, then 10 cylinders might be sufficient. However if CICS PA encounters an out-of-space condition (ABENDx37) during load, then it simply closes the data set and recommences loading in a new data set. You can decide to specify a larger size initially and adjust it later using HDB Maintenance.

When you load a statistics HDB, you can also choose to export the data to DB2®. The DB2 Load column identifies the statistics reports that are exported.
