For example:. Oracle Database Security Guide for more information on privileges and roles. Certain user accounts are created automatically for database administration.

Other accounts are automatically created just so that individual Oracle Database XE features or products can have their own schemas. These automatically created accounts are called internal us er accounts , and their schemas are called int ernal schemas. Do not attempt to log in with other internal accounts. Administrative accounts and privileges enable you to perform administrative functions like managing users, managing database memory, and starting up and shutting down the database.

They are both created with the password that you supplied upon installation Windows operating systems or configuration Linux operating systems. This is the use r account that you log in with to perform all administrative functions other than starting up and shutting down the database. All ba se tables and views for the database data dictionary are stored in the SYS schema. These base tables and views are critical for the operation of Oracle Database XE. To maintain the integrity of the data dictionary, tables in the SYS schema are manipulated only by the database.

They should never be modified by any user or database administrator. You must not create any tables in the SYS schema.

There is typically no reason to log in as user SYS. See "Starting Up and Shutting Down" for more information. It enables SYS to perform high-level administrative tasks such as starting up and shutting down the database. Operating system authentica tion OS authentication is a way of using operating system login credentials to authenticate database users.

One aspect of OS authentication can be used to authenticate database administrators. If you log in to the Oracle Database XE host computer with a user name that is in a special operating system user group, you are then permitted to conn ect to the database with the SYSDBA privilege.

OS authentication is needed because there must be a way to identify administrative users even if the database is shut down. A user authenticated in this way can then start up the database.

Table lists the operating system user groups whose member users can connect to the database with the SYSDBA privilege. On each platform, if the OS authentication user gro up does not already exist, it is automatically created when you install Oracle Database XE. In addition, upon installation on the Linux platform, the user account oracle is automatically created and placed in the dba group. On both platforms, you can add other host users to the OS authentication user group to enable them to connect to the database with the SYSDBA privilege.

Table Database Administrator Login Methods. For routine administrative tasks like managing memory and managing users. For routine administrative tasks like managing users. An administrator must first grant the DBA role to the user. For high-level administrative tasks like starting up and shutting down the database, and changing the SYS password. An administrator must have previously logged in and granted the DBA role to this user.

Remember that when you connect with OS authentication, you are effectively logging in to the database as user SYS. This section discusses using SQL Developer, and contains the following topics:.

This displays nodes for all database users, including several Oracle-supplied internal users. The Connections navigator hierarchy may look like this:. To create a new database user, right-click the Other Users node in the Connections navigator and select Create User. To perform an action on a database user, right-click that user in the hierarchy and select the appropriate command Edit User or Drop User. Before creating a user, determine the following:.

If so, on the Create Database User page, grant individual session-related and create object system privileges. See the following topics for more information:. The Overflow Blog. Podcast Helping communities build their own LTE networks.

Manage how update sets store, retrieve, preview, and apply configuration changes between instances. These procedures help you manage your customizations and resolve potential collisions before you move them to another instance.

When an update set is completed, you can transfer it between instances to move customizations from development, through testing, and into production.

Batch update sets enable you to group update sets together so you can preview and commit them in bulk. An update set is an XML file that contains: A set of record details that uniquely identify the update set. A list of configuration changes. A state that determines whether another instance can retrieve and apply configuration changes. Asked 7 years, 8 months ago. Active 7 years, 8 months ago. Viewed 1k times. How do i fix this?
