Screen Description

The System Run Unit Summary screen displays a line of information for each of these types of system transactions:

You can request a detailed display for a specific run unit. Type any nonblank character in the select field to the left of a run unit type, then press [Enter]. The Realtime Monitor displays the Specific System Run Unit Detail screen.

What To Look for

If the number of overflow run units (Total Ovrflw) is a high percentage of the total number of run units (Total Alloc) for the same run unit type, you should consider increasing the number of run units specified in the appropriate RUNUNITS FOR parameter of the system generation SYSTEM statement. The current RUNUNITS FOR parameter specification appears in the Sysgen Number column.

Overflow run units may be high for LOADER run units. This typically occurs when the DC/UCF system accesses the load areas of alternate dictionaries. In this case, increasing the RUNUNITS FOR parameter will not reduce the number of run units. Users who specify an alternate dictionary (using the DCUF SET DICTNAME command) must be careful to reset the dictionary specification when they are finished (using the DCUF SET DICTNAME ' ' command).
