Installing DB2 Servers > Response file installation >
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.
Restrictions
Be aware of the following limitations
when using the response files method to install DB2® on Linux or UNIX platforms:
- 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 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 will take 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.
Prerequisites
Before you begin the installation,
ensure that:
- Your system meets all of the memory, hardware, and software requirements
to install your DB2 product.
- All DB2 processes are stopped.
If you are installing a DB2 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.
To perform a response file installation:
- Mount your DB2 product
DVD or access the file system where the installation image is stored.
- Create a response file using
the sample response file
Response files have
a file type of .rsp. For example, ese.rsp.
- Install DB2 using a response file
