WIZIVP: The Interval Chopper › Operations

Operations

To execute the Interval Chopper you must:

Include a CALL statement for the Interval Chopper program, WIZIVP, in the control statements for the run. For example:

CALL WIZIVP

Define a value for the Interval Chopper field INTERVAL. INTERVAL is used by the Interval Chopper to specify the reporting interval. If no value is specified, CA JARS Wizard assumes a default of 15 minutes. Use the following format when defining INTERVAL:

DEFINE(K) INTERVAL EQ n

The (K) suffix code is appended to the DEFINE statement because INTERVAL is a constant field that is maintained strictly by you. Specify n as a value from 1 to 60 minutes. The value of n must be evenly divisible into 60. For example,

DEFINE(K) INTERVAL EQ 12

This defines the INTERVAL as 12 minutes. Notice that 12 divides evenly into 60 (5 times); there is no remainder.

Once the value of INTERVAL has been defined, CA JARS Wizard reads all the records in the input file and adds them to the appropriate time interval record. If an input file record extends over more than one time interval, multiple segments of the input record are created to allocate the input record statistics to your user-defined time interval records.

For each time interval record generated, two fields are created: INTERVAL START and INTERVAL LENGTH. These contain the starting time of the record (INTERVAL START) and the length of the record (INTERVAL LENGTH). Each of these fields can be used for sorting and breaking operations. Time analysis reports can then be produced.
