Please see see Chapter 2, "Installing the Mobile Client" in the Oracle Database Mobile Server Mobile Client . It covers the details of client installs.
BDB comes as prebuilt binaries for DMS and they are built to be compatible with needs of the DMS client. These binaries are bundled in with the
DMS download. You do NOT need to separately download BDB and build it.
In Chapter 4 of the Mobile Server Installation guide it covers the server side of the install.
Do you have a DMS license?
