Choosing whether to install DB2 Express

You can choose to have the installation process include automatically installing an instance of IBM DB2® Express. Choose this option if you do not have an existing or planned supported database server you intend to use to store content from Process Center or Process Server. If you are installing a test or proof-of-concept environment, you would likely choose to have a new DB2 Express installed automatically, unless one already exists on the system.

Choices you make for other installation options affect what is available for this choice. If you want the generated instructions to include automatically installing DB2 Express, you must install on Windows or Linux on an Intel system. If you are installing any product configuration onto Linux on System z, Linux on Power, Linux on Power LE, AIX, or Solaris, the installation process does not offer to install DB2 Express; you must use a database server product that you have already installed or will install.

You cannot install DB2 Express on any system that already has DB2 installed on it. You must install as an administrative or root user to install DB2 Express. If you are installing as a nonadministrative user or as an installation group user, you must install the database separately.

The configuration steps configure Process Center or Process Server to use the database of your choice, regardless of whether you automatically install a new DB2 Express instance or you are using an otherwise-installed supported database server.
