EDH_ANZDBA: Data extraction

EDH_ANZDBL: Analysis of extracted data

These tools are based on statistical activity database available with DSPFD.

There is no need to activate journaling for this analysis.

A physical file stores the list of files and its members.

For each file, we store the record length and 5 groups of counters:

• The first group stores current counters of the file.

The 3 others groups store counters that have been picked up during 3 analysis.

The command EDH_ANZDBA performs 3 analysis (Submission of a batch job by the command).

• EDH_ANZDBA is used for storing the current value of counters (*INIT)

EDH_ANZDBA (YourLibrary) PERIOD(*INIT)

• We re-use the command at 3 different periods of time:

  • After jobs batches

EDH_ANZDBA (YourLibrary) PERIOD(*PERIOD2)

• After 24 hours

EDH_ANZDBA (YourLibrary) PERIOD(*PERIOD3)

• After a week

EDH_ANZDBA (YourLibrary) PERIOD(*PERIOD4)

The second command EDH_ANZDBL allows you to print data into a spool file.

• Compares the selected periods to the initial values

EDH_ANZDBL TOPERIOD(*PERIODn)

• Adds all the entries (Add, Update, Delete) for each file and multiplies them by the record length

You can also compare 2 periods:

EDH_ANZDBL FRMPERIOD(*PERIOD2) TOPERIOD(*PERIOD3)
