When we buy new device such as HP Serviceguard Toolkit for Oracle Data Guard we often through away most of the documentation but the warranty.
Very often issues with HP Serviceguard Toolkit for Oracle Data Guard begin only after the warranty period ends and you may want to find how to repair it or just do some service work.
Even oftener it is hard to remember what does each function in Software HP Serviceguard Toolkit for Oracle Data Guard is responsible for and what options to choose for expected result.
