Before you install HCL
OneDB™
database server products, you must prepare your system and plan for choices that you must make
during the installation process.
About this task
Preparing for installation includes reviewing system
requirements, planning how to upgrade, deciding on the installation
owner and the installation directory, reviewing installation options,
and gathering information if you want to create a database server
during installation. It also includes preinstallation tasks such as
obtaining the software and reviewing the machine notes.
Procedure
To prepare for installation:
-
Obtain the software and configure a License Server to obtain licenses to run HCL
OneDB.
-
Review the HCL
OneDB components that
can be installed with the database server.
You can install all of them or some of them.
-
Ensure that your computer meets the system requirements.
-
Choose a user account with which to install the product. The user account becomes the
installation owner.
- UNIX, Linux: Decide between a non-root owner and
an owner with root or administrative privileges.
- If you plan to install as an administrative user, decide on a password for user
informix.
-
Choose an installation directory.
If the database server is already installed, decide on the upgrade path.
-
Decide between a typical or custom installation.
- Choose a typical installation in the following cases:
- For default server features, language support, extensions, and tools.
- To create a configured database during installation with connectivity for JSON
applications and multiple storage spaces for data.
- Choose a custom installation if you want to have any of the following options:
- To install a subset of database server components.
- In root-based installation, to set up event auditing for the security policies
of your organization.
- To create a configured database server during installation with one storage
space for data.
- To prepare a response file for a non-interactive installation.
Depending on your operating system, you can choose other types of
installations that have similar options to a custom installation. UNIX, Linux: You can choose the Legacy installation to
prepare a script-based installation. Linux: You can choose the RPM installation to
generate an RPM package.
Results
Log files are created during
the installation process. You can use the log files to troubleshoot
installation errors.
What to do next
After you install the database server, you can create
the demonstration databases that are included with the database server.
Many examples in the documentation and in the $ONEDB_HOME/demo (UNIX,
Linux) or the %ONEDB_HOME%\demo (Windows)
directory are based on the demonstration databases. You can use the
demonstration databases to explore database server features. You can
create the demonstration databases at any time after installation
by running the dbaccessdemo command. See Demonstration databases.
