Working with instances on the same or different Db2 copies
You can run multiple instances concurrently, in the same Db2 copy or in different Db2 copies.
About this task
To prevent one instance from accessing the database of another instance, the database files for
an instance are created under a directory that has the same name as the instance name. For example,
when creating a database on drive C: for instance DB2, the
database files are created inside a directory called C:\DB2. Similarly, when
creating a database on drive C: for instance TEST, the
database files are created inside a directory called C:\TEST. By default, its
value is the drive letter where Db2 product is installed.
For more information, see the dftdbpath database manager configuration
parameter.
