ALTER PACKAGE

Description

Changes the attributes of a package or recompiles a package.

Precautions

• Currently, only users with the ALTER PACKAGE OWNER permission can run this command. The system administrator has this permission by default. The restrictions are as follows:
  • The current user must be the owner of the package or the system administrator and a member of the new owner role.
• When separation of duties is enabled, to change the owner of a package, users must have the user group permission, even a system administrator. The owner of a package of the DEFINER type cannot be changed.
• Only the initial user can change the owner of a package to the initial user.
• When separation of duties is disabled, only a system administrator or a higher-level user can change the package owner, but the owner cannot be changed to an O&M administrator.
• The system administrator is not allowed to change the owner of a package of the DEFINER type to the initial user or O&M administrator.

Syntax

• Change the owner of a package.

  ALTER PACKAGE package_name OWNER TO new_owner;

  

• Recompile the package.

  ALTER PACKAGE package_name COMPILE [PACKAGE | BODY | SPECIFICATION];

  

Parameters

• package_name

  Specifies the name of the package to be modified.

  Value range: an existing package name. Only one package can be modified at a time.

• new_owner

  Specifies the new owner of a package. To change the owner of a package, the new owner must have the CREATE permission on the schema to which the package belongs.

  Value range: an existing user role.
