SYSAUX Tablespace was introduced in Oracle 10g. The SYSAUX tablespace is an auxiliary tablespace to the SYSTEM tablespace. Many database components use the SYSAUX tablespace as their default location to store data. Therefore, the SYSAUX tablespace is always created during database creation or database upgrade.
Unlike SYSTEM tablespace if SYSAUX tablespace is unavailable database will not go down but some of the features may not be available.

 Name                       Null?    Type
 ----------------------------------------- -------- ----------------------------
 OCCUPANT_NAME                        VARCHAR2(64)
 OCCUPANT_DESC                        VARCHAR2(64)
 SCHEMA_NAME                        VARCHAR2(64)
 MOVE_PROCEDURE                     VARCHAR2(64)
 MOVE_PROCEDURE_DESC                    VARCHAR2(64)
 SPACE_USAGE_KBYTES                    NUMBER

The SYSAUX tablespace provides a centralized location for database metadata that does not reside in the SYSTEM tablespace. It reduces the number of tablespaces created by default, both in the seed database and in user-defined databases.

During normal database operation, Oracle Database does not allow the SYSAUX tablespace to be dropped or renamed. Transportable tablespaces for SYSAUX is not supported.
