Under option D.1, line command S in front of a dynamic database provides the same information as the IDCAMS LISTCAT command. If the selected database does not support dynamic extension (e.g. a SPOOL database), the amount of information provided is reduced. The examples below show the results for a dynamic database.

Warning threshold/
|
These values are displayed only if the optional MAXSIZE value has been defined for this database in the database definition file: Warning threshold is a user-defined value (in cylinders) which can be used to monitor the growth of dynamic databases when extents are formatted (messages 9549I and 9549W). Allocated displays the amount of allocated space (in percent) in relation to the warning threshold. |
