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. After you generate the response file, it must be tailored to your environment. Once tailored, you can then perform the silent 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 may include performing the following steps:
- If you are using environment variables to specify system database and server credentials, then you must begin by setting these environment variables. See Using environment variables for server and system database credentials.
- You must create a response file using the installer as described in any of the following topics. Note that an installation or upgrade of the server occurs when using the installer to generate a response file.
- 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:
- You must perform the silent upgrade using the response file as described in Performing a silent upgrade.
