NEW ELAPSED SEC PACKAGE

Create new field in KPM_DB2_PACKAGE_H
In KPM_DB2_PACKAGE_H there is PKG_ELAPSED_SEC
(Total elapsed time for executing the package. From QPACSCT).
In this field the value of elapsed time is very high only for DB2 Batch because in the summary the tool doesn't discard parallel rollup record .
We ask you to create a new field purified from parallel rollup record that you must identified
by QWACFLGS='.........1......' (11th byte set to 1 ), and you must summary the elapsed real time of job batch.

    Most likely already communicate but somewhat must presume that the reader understands "CPU parallelism" concept pertaining to DB2 - relevant field to test (as mentioned) is QWACFLAGS - here is the laymen's consideration about how/when to populate this field PKG_ELAPSED_SEC:

    • For DB2 SMF 101 subtype 1 records representing non-parallel tasks and for the parent record of a DB2 parallel query (test-values of 'NONE', 'PARENT', or 'ACUMAC'), populate PKG_ELAPSED_SEC with the value input from field QPACSCT in the Package/DBRM Accounting Data Section of the SMF type 101/1 record.

    • Otherwise, for a parallel child subtask (test-values of 'CHILD' or 'ROLLUP'), PKG_ELAPSED_SEC is to be set equal to 0, since it is not relevant here.

    Now, if you require DB2 SMF 101 candidate example data, that's another story....the above scenario represents the use-case clearly -- but one must also understand CPU parallelism within DB2 Accounting data source as well.
