Miscellaneous LOB data report and trace

The miscellaneous LOB data report shows general information about large objects.

This block provides miscellaneous data for large objects (LOBs). For formatting reasons, OMEGAMON for Db2® PE shows different labels for report and trace. The following example shows both layouts, the report on the left, and the trace layout on the right.
