Allocation Manager

Allocation Manager, part of the Index Manager, performs these tasks:

When one of these tasks must be performed, the Allocation Manager uses this process to allocate space:

  1. It attempts to use free space in an existing file.

  2. If not enough free space is available, it attempts to expand an existing file.

  3. If not enough free space is available in existing files, it creates a file on the current volume.

  4. If it cannot expand a file or create a file on the specified volume, it attempts to use the next specified volume.

  5. If all specified volumes are full, an error message is displayed, and the transaction is aborted.

The Allocation Manager allocates space for index and data files based on the database settings for storage.
