STATUS display-option reserve-option
where
Specifies FULL to print detailed statistics for the database and data sets or INDEX to print detailed statistics for the database only.
If the parameter is omitted, summary statistics for the database and data sets are printed.
Specifies either RESERVE to place a reserve on the database for the duration of the database evaluation process or NORESERVE to not place a reserve on the database.
This option is only applicable when specified with the display-option. Because the database is updated by many tasks, jobs, or online sessions, the database data can change during the evaluation process, causing inconsistent statistics. The RESERVE option delays external updates to the database for the purpose of obtaining consistent statistics. If reserve-option is omitted, NORESERVE is assumed.
To compile detailed statistical information, the entire database must be read. Depending on the size of the database, this process can take a considerable amount of time.
