Database Activity Detail for a Data Sharing Group view (IDAGDTLR)
The Database Activity Detail for a Data Sharing Group view (IDAGDTLR) provides information about database I/O activity and DL/I calls for a data sharing group.
You can use the IDAGDTLR view to analyze I/O information related to logical and physical databases. The view helps you recognize and solve N-way data sharing problems resulting from I/O contention or buffer cross-invalidation, and it shows DL/I call and I/O event totals, rates, and average times.
The IDAGDTLR view reports DEDB activity if the Event Collector parameter DBFPLVL is set to collect DEDB activity, but it does not report MSDB or GSAM database activity or activity caused by background write.
| For more information, view the Quick Course 'MainView for IMS - Region and Database Activity'. |
You can hyperlink to the IDAGDTLR view from the
- Database Activity option in the IMS SSI Easy Menu (EZISSIR) and the DBCTL Operations Menu (EZDOPSR)
- System DB Activity option in the DBCTL DBA Easy Menu (EZIDBA)
- Data ShrGrp field in the IDASSUMR view
