default tablespace for non-core system usersWhen you create an Oracle instance, you create non-core users, such as DBSNMP, ODM, Perfstat, and so on, in addition to creating users such as SYS, system cores, and so on. These users are using system as their default tablespace in 9i. These users, once used, also generate a large amount of data to occupy the system table space.In oracle10g, a new tablespace sysaux is used as the default table space for th
