Displays a variety of Sybase IQ status information about the current database.
sp_iqstatus
DBA authority required. Users without DBA authority must be granted EXECUTE permission to run the stored procedure.
Shows status information about the current database, including the database name, creation date, page size, number of dbspace segments, block usage, buffer usage, I/O, backup information, and so on.
sp_iqstatus displays an out-of-space
status for main and temporary stores. If a store runs into an out-of-space
condition, sp_iqstatus shows Y in
the store’s out-of-space status display value.
sp_iqspaceused returns a subset of the same information as provided by sp_iqstatus, but allows the user to return the information in SQL variables to be used in calculations. See “sp_iqspaceused procedure”.
To display space that can be reclaimed by dropping connections, use sp_iqstatus and add the results from the two returned rows:
(DBA)> select * from sp_iqstatus() where name like '%Versions:%' Execution time: 6.25 seconds Name Value ---------------------------- Other Versions: 2 = 1968Mb Active Txn Versions: 1 = C:2175Mb/D:2850Mb (First 2 rows)
The above example output shows that one active write transaction created 2175MB and destroyed 2850 MB of data. The total data consumed in transactions and not yet released is 4818MB, or 1968MB + 2850MB = 4818MB.
sp_iqstatus does not show blocks that will be deallocated at the next checkpoint. These blocks do however, appear in sp_iqdbspace output as type X.
The following output is from the sp_iqstatus stored procedure:
