The DATA_DICTIONARY keyword in Oracle

The DATA_DICTIONARY keyword contains parameters that determine the storage settings for specific ArcSDE geodatabase system tables.

Most geodatabases in Oracle do not require more than one tablespace for the ArcSDE repository tables. However, if you anticipate the need to manage space for the following segments independently of the rest of the ArcSDE system tables, create one or more tablespaces for those segments when you create your Oracle database. If you do create additional tablespaces, place them on a fast storage volume such as RAID 10.

If you want to store business tables and indexes, states tables and indexes, and/or ArcSDE XML tables and indexes in different tablespaces, uncomment the appropriate TABLESPACE line or lines in the dbtune.sde file and type your tablespace names in the line before you create your geodatabase.
