DB2 10.5 for Linux, UNIX, and Windows

Directory structure for your installed DB2 database product (Windows)

When you install DB2® database products, you can specify a DB2 database product installation path or else use the default path. After installation, DB2 objects are created in these directories.

Follow these steps to verify the DB2 product you have installed on Windows.
  1. From a command prompt, type the regedit command. The Registry Editor window opens.
  2. Expand HKEY_LOCAL_MACHINE > Software > IBM > DB2
The DB2 product you have installed will be displayed.
The following table shows the location of DB2 objects after a default installation.

The following figures illustrate an example of the DB2 directory structure after installation on Windows operating systems using the default options. In these figures, there are two instances, DB2 and MYINST. The directories DB2 and MYINST under the local disk C: will only appear if a database has been created under the appropriate instance.
