Monitor Databases
This section describes information that is available to you about OnLine
databases. Monitor databases to track disk space usage by database.
From DB-Monitor
From DB-Monitor, select the Status menu, Databases option.
This option lists all OnLine databases (up to a limit of 100). For each database,
DB-Monitor provides the following information:
■ Database name
■ Database owner (user who created the database)
■ Dbspace location where the system catalog for this database resides
■ Date that the database was created (or the time, if the database was
created today)
■ Logging status flag of the database
Logging status is indicated with three flags: B for buffered logging, N for no
logging, and U for unbuffered logging. If an asterisk appears by the U, the
database is ANSI-compliant.
From the Command Line
From the command line, execute tbcheck -pc with a database name as a
parameter to obtain further information about every table in the database.
The table information is derived from the database system catalog and
includes the following data:
■ Whether the table includes VARCHAR or blob columns
■ Number of extents allocated
■ First and next extent sizes
■ Count of pages used and rows stored
