A silent upgrade may be preferred when automating the upgrade of one or more Hybrid Data Pipeline servers. The silent upgrade process hinges on the creation of a response file. The response file is a text file that you create (for example, pipeline.response) with the product installer. You begin by generating a response file, you then tailor the response file to your environment, and you then perform the upgrade installation.
If you are using the silent installation process to upgrade cluster nodes, the response file generated during the initial upgrade must be modified to upgrade the server on any additional nodes. For a GUI generated response file, you will need to designate the name of an additional node with the D2C_HOSTNAME option. For a console generated response file, you will need to designate the name of an additional node with the D2C_HOSTNAME_CONSOLE option.
A silent upgrade requires performing the following steps:
1. You must create a response file using the installer as described in any of the following topics.
2. You must edit the response file to suit your environment. Response files differ depending on whether you generate them using the installer in GUI mode or console mode. Editing the response file is described in the following topics:
