Using an IBM Db2 database
If you want to use an IBM Db2 database, ensure that the database is installed and configured for use with WebSphere Commerce. If you want to use a remote database, then ensure that the Db2 client is installed before you install WebSphere Commerce.
Note: The Db2 registry variable Db2_COMPATIBILITY_VECTOR is not supported.
Before you begin
- If you are using a remote database, install the appropriate Db2 client to access the remote Db2 database. For more information, see your Db2 documentation.
- Check your version of Db2 database by issuing the following command from a Db2 command line:
db2level
- Your existing Db2 database installation must be Db2 Enterprise Server Edition Version 10.5 Fix Pack 5 or later.
- For information about installing Db2 Version 10.5, see Installing DB2 database servers.
- For information about applying Db2 fix packs, see Applying fix packs in DB2 database environments.
If you are on WebSphere Commerce Version 8 Mod Pack 1 or later, you can choose upgrade your existing IBM Db2 Version 10.5 database to IBM Db2 Enterprise Server Edition Version 11.1 or a later 11.1 Fix Pack. For more information about upgrading to Version 11.1, see Upgrading runtime environments to use IBM Db2 Version 11.1.
Note: IBM Db2 Version 11. includes new optimization and has different performance characteristics designed to support high load environments with high concurrency.
