This operation performs the following actions:

• Activates an object using the Servant supplied to service objects of the type rep_id, using the supplied stroid (a stringified ObjectId), which must have been obtained by a previous call on start_persistent_systemid.
• Sets the ORB and the POA into the state in which they will accept requests on that object.
• Returns an object reference to the object activated.
• The reactivation would be done using the restart_persistent_systemid method.
