Initializing Disk Space

Disk-space initiali zation uses the values stored in the configuration file to create the initial chunk of the root dbspace on disk and to initialize shared memory. When you initialize disk space, shared memory is automatically initialized for you as part of the process.

Typically, you initialize disk space just once in the life of an database server. This action occurs when you bring the database server online for the first time.

Warning:

When you initialize the database server disk space, you overwrite whatever is on that disk space. If you reinitialize disk space for an existing database server, all data in the earlier database server instance becomes inaccessible and, in effect, is destroyed.

For information on initializing the database server, see Initializing Disk Space.
