Checking State on Disk (Informix) 

Use

You can use the detailed database analysis in the SAP/Informix database monitor to check the state of tables, indexes, and dbspaces on disk. For example, you can find out how large your database is, how large certain tables are, and which objects have an excessive number of extents. Checks for full dbspaces and missing indexes are particularly important.
