Oracle Database 11g Building Oracle XML DB Applications

Version Control

The DBMS_XDB_VERSION and DBMS_XDB PL/SQL packages provide a way to create and manage a Version Controlled Resource (VCR) in XML DB Repository.

When an XML DB Repository resource is turned into a VCR, a flag is set to mark it as a VCR and the current resource becomes the initial version.

To make an XML DB Repository resource versioned, run the following command (create_vcr.sql):

Listing 3-13 Creating a VCR from an XML DB Repository Resource

declare

     v_resid DBMS_XDB_VERSION.RESID_TYPE;

begin

     v_resid := dbms_xdb_version.makeversioned(‘/public/chp03/john_smith.xml’);

end;

/

Commit;

You have to commit to complete the preceding operation.
