AutoCollect Process › Creating the Snapshot Rowsets

Creating the Snapshot Rowsets

The AutoCollect process provides a specific methodology to take snapshots of selected DST tables and record them in a permanent database for analysis and reporting.

Multiple DST tables are collected in a given snapshot and the number of rows collected from each table vary. The AutoCollect functions assign a unique identifier (key value) to each row of a given snapshot. In this way, all rows from the different tables can easily be found. To make it easier to refer to the collection of rows that make up a snapshot, we have created the term ROWSET. A rowset refers to all the rows (in all tables) that make up a given snapshot or delta. Delta rowsets are discussed later in this section.

For AutoCollect to collect as much data as possible, verify that the collection is executed one last time just before the MUF terminates.

The purpose of AutoScope is to collect and analyze performance statistics over given periods. The occasional missed snapshot collection should not reduce its overall value to you.
