Manage disk space

You can use several utilities and tools to manage disk spaces and the data that the database server controls.

You can use the following utilities to manage storage spaces:

  • The onspaces utility commands
  • SQL administration API commands

Your HCL OneDB™ Performance Guide also contains information about managing disk space. In particular, it describes how to eliminate interleaved extents, how to reclaim space in an empty extent, and how to improve disk I/O.

You can generate SQL administration API or onspaces commands for reproducing the storage spaces, chunks, and logs that exist in a file with the dbschema utility.
