Collecting report data with the Near-Term History Data Collector

If the Near-Term History Data Collector is configured to store collected data in sequential data sets, the contents of these data sets can be used as input for OMEGAMONĀ® for Db2 PE reports and trace reports.

The Near-Term History Data Collector can be configured to store data in various types of data sets, for example sequential data sets, Generation Data Group (GDG) data sets, and VSAM data sets. The configuration is done with the Configuration Tool, the currently active configuration can be viewed by means of the OMEGAMON for Db2 PE Classic Interface in the Near-Term History Data Collection Options panel.

Ensure that collected data is written to sequential data sets by one of the following methods:
  • The near-term history data collection options keyword WRITEOPTION in data set member RKD2PAR(COPT<ssid>) should have the value VSAM,SEQ.
  • In the Near-Term History Data Collection Options panel you should see Writeoption=VSAM,SEQ. This panel also lists the currently used data sets where collected data is stored.
