那么这些用户到底是干什么的,我怕误人子弟,翻了一下联机文档,还是看看他们的解释吧:

Account that allows HTTP access to Oracle XML DB. It is used in place of the APEX_PUBLIC_USER account when the Embedded PL/SQL Gateway (EPG) is installed in the database.
EPG is a Web server that can be used with Oracle Database. It provides the necessary infrastructure to create dynamic applications.

The account used to administer Oracle Text. Oracle Text enables you to build text query applications and document classification applications. It provides indexing, word and theme searching, and viewing capabilities for text.
See Oracle Text Application Developer's Guide.

The account used by the Management Agent component of Oracle Enterprise Manager to monitor and manage the database.
See Oracle Enterprise Manager Grid Control Installation and Basic Configuration.

The account used internally to access the EXFSYS schema, which is associated with the Rules Manager and Expression Filter feature. This feature enables you to build complex PL/SQL rules and expressions. The EXFSYS schema contains the Rules Manager and Expression Filter DDL, DML, and associated metadata.
See Oracle Database Rules Manager and Expression Filter Developer's Guide.

The account used to administer Oracle Label Security (OLS). It is created only when you install the Label Security custom option.

The Oracle Multimedia user. Plug-ins supplied by Oracle and third-party, format plug-ins are installed in this schema.
Oracle Multimedia enables Oracle Database to store, manage, and retrieve images, audio, video, DICOM format medical images and other objects, or other heterogeneous media data integrated with other enterprise information.
See Oracle Multimedia User's Guide and Oracle Multimedia Reference.

The account that supports plan stability. Plan stability prevents certain database environment changes from affecting the performance characteristics of applications by preserving execution plans in stored outlines. OUTLN acts as a role to centrally manage metadata associated with stored outlines.
See Oracle Database Performance Tuning Guide.
