Response file installation of Db2 overview (Linux and UNIX)
This task describes how to perform response file installations on Linux® or UNIX. You can use the response file to install additional components or products after an initial installation. A response file installation might also be referred to as a silent installation or an unattended installation.
Before you begin
Before you begin the installation, ensure that:
- Your system meets all of the memory, hardware, and software requirements to install your Db2 database product.
- All Db2 processes are stopped. If you are installing a Db2 database product on top of an existing Db2 installation on the computer, you must stop all Db2 applications, the Db2 database manager, and Db2 processes for all Db2 instances and Db2 DAS related to the existing Db2 installation.
Be aware of the following limitations when using the response files method to install Db2 on Linux or UNIX operating systems:
- If you set any instance or global profile registry keywords to BLANK (the word "BLANK"), that keyword is, in effect, deleted from the list of currently set keywords.
- Ensure that you have sufficient disk space before installing. Otherwise, if the installation fails, manual cleanup is required.
- If you are performing multiple installations or are installing Db2 database products from multiple DVDs, it is recommended that you install from a network file system rather than a DVD drive. Installing from a network file system significantly decreases the amount of time it takes to perform the installation.
- If you are planning on installing multiple clients, set up a mounted file system on a code server to improve performance.
To perform a response file installation:
- Mount your Db2 database product DVD or access the file system where the installation image is stored.
- Create a response file by using the sample response file.
Refer to Creating a response file using the sample response file.
Response files have a file type of
.rsp. For example, ese.rsp.
