You can connect to a Db2 database using two methods. The recommended method is to use connection strings, as these can be used for both 32-bit and 64-bit client connections. Connection strings are configured using the connect attribute within the database configuration file. You can also connect using the ODBC data source method that is used for other database types.
Db2 region and cross-region databases can be created in their own database, or you can store them in a single database. This database may also contain one or more datastore databases.
Use these steps to configure region and cross-region databases in Db2.
