Using the Disk Usage Utility in Online Mode

If you select the online (default) mode, all other conditions for usage must have been met and Oracle must be installed and running before you use the utility. If you are running ora11du / ora12du on the active dictionary, the product line must currently be in Oracle. If you are running ora11du / ora12du on either a new or old dictionary, the product line must have been in Oracle when that dictionary was built. When running in online mode, the utility queries the Oracle database for information on the existence and size of database spaces and other parameters necessary for determining required disk space. When run in online mode, ora11du / ora12du also checks the Oracle database to determine how much space you have available in your tablespaces.

ora11du / ora12du -[c][w]bx dataarea [tablespace...]

In online mode, the ora11du / ora12du utility run has the following options:


`-c`	Show information about the existing Oracle tablespaces.
`-w`	Show detailed warning messages for tables and indexes.
`-bx`	Use a block size of `x`K. This must be the last specified option in the command line.
