You cannot grant this system privilege to roles. Use and reference object types and collection types in any schema, and invoke methods of an object type in any schema if you make the grant to a specific user. If a user has been granted the MERGE ANY VIEW privilege, then for any query issued by that user, the optimizer can use view merging to improve query performance without performing the checks that would otherwise be performed to ensure that view merging does not violate any security intentions of the view creator.
Create a registration on queries and receive database change notifications in response to DML or DDL changes to the objects associated with the registered queries. Please refer to Oracle Database Application Developer's Guide - Fundamentals for more information on database change notification. Caution: This is a very powerful system privilege, as it lets the grantee bypass application-driven security policies. Database administrators should use caution when granting this privilege.
Force the commit or rollback of the grantee's in-doubt distributed transactions in the local database. Query any data dictionary object in the SYS schema. Caution: This is a very powerful system privilege, as it lets the grantee view all data in the database, including past data.
This privilege should be granted only to users who need to use the Oracle Flashback Transaction Query feature. These roles are provided for compatibility with previous versions of Oracle Database. Note: Oracle recommends that you design your own roles for database security rather than relying on these roles.
These roles may not be created automatically by future versions of Oracle Database. See Also: Oracle Database Utilities for more information on these roles. Table Oracle Database Predefined Roles. A DBA using Oracle Database heterogeneous services needs this role to access appropriate tables in the data dictionary.
It includes all of the job scheduler system privileges and is included in the DBA role. Note 1: Oracle Database treats a Java class, source, or resource as if it were a procedure for purposes of granting object privileges.
The following table privileges authorize operations on a table. The following view privileges authorize operations on a view. Create a subview under this view. The following procedure, function, and package privileges authorize operations on procedures, functions, and packages. These privileges also apply to Java sources, classes, and resources , which Oracle Database treats as though they were procedures for purposes of granting object privileges.
Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object. Place a breakpoint or stop at a line or instruction boundary within the procedure, function, or package.
This privilege grants access to the declarations in the method or package specification and body. Execute the procedure or function directly, or access any program object declared in the specification of a package, or compile the object implicitly during a call to a currently invalid or uncompiled function or procedure. Access, through a debugger, public variables, types, and methods defined on the procedure, function, or package.
This privilege grants access to the declarations in the method or package specification only. Note: Users do not need this privilege to execute a procedure, function, or package indirectly. The following materialized view privileges authorize operations on a materialized view. Synonym privileges are the same as the privileges for the base object.
Granting a privilege on a synonym is equivalent to granting the privilege on the base object. Similarly, granting a privilege on a base object is equivalent to granting the privilege on all synonyms for the object. If you grant to a user a privilege on a synonym, then the user can use either the synonym name or the base object name in the SQL statement that exercises the privilege.
The following directory privileges provide secured access to the files stored in the operating system directory to which the directory object serves as a pointer. The directory object contains the full path name of the operating system directory where the files reside. Because the files are actually stored outside the database, Oracle Database server processes also need to have appropriate file permissions on the file system server. Granting object privileges on the directory database object to individual database users, rather than on the operating system, allows the database to enforce security during file operations.
Write files in the directory. This privilege is useful only in connection with external tables. It allows the grantee to determine whether the external table agent can write a log file or a bad file to the directory. The following object type privileges authorize operations on a database object type. Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object type. Create a subtype under this type. The following operator privilege authorizes operations on user-defined operators.
Granting System Privileges to a Role: Example The following statement grants appropriate system privileges to a data warehouse manager role, which was created in the "Creating a Role: Example" :. Both roles were created in the "Creating a Role: Example" :. The user hr can subsequently generate the next value of the sequence with the following statement:. However, because the GRANT statement lists only these columns, oe cannot perform operations on any of the other columns of the employees table.
For security reasons, Oracle recommends that you use this setting only with great caution. Alter a refresh-on-demand materialized on any table in the database to refresh-on-commit. Reference public package variables in any schema. This privilege also allows the creator to: Assign quotas on any tablespace. Set default and temporary tablespaces. This privilege authorizes the grantee to: Change another user's password or authentication method. Assign quotas on any tablespace.
Assign a profile and default roles. Induce the failure of a distributed transaction. You cannot grant this privilege to a role. DEBUG Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object. EXECUTE Execute the procedure or function directly, or access any program object declared in the specification of a package, or compile the object implicitly during a call to a currently invalid or uncompiled function or procedure.
READ Read files in the directory. DEBUG Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object type. Place a breakpoint or stop at a line or instruction boundary within the type body. Access, through a debugger, public variables, types, and methods defined on the object type.

Question and Answer. You Asked Dear Team. Thanks and Regards,. The derby. You can grant privileges on an object if you are the owner of the object or the database owner. The syntax that you use for the GRANT statement depends on whether you are granting privileges to a schema object or granting a role. This privilege can be granted to users and to roles.
If a schemaName is not provided, the current schema is the default schema. If a qualified sequence name is specified, the schema name cannot begin with SYS. If a qualified type name is specified, the schema name cannot begin with SYS. Only the database owner can grant a role.
