At current time, the DB2 Rails Adapter (ibm_db2_adapter.rb) has a direct dependency on the DB2 Ruby driver (ibm_db2) which in turn has a similar direct dependency on the DB2 CLI driver. In DB2 version 8.x this dependency implies at least *DB2 Run-Time Client Lite* install (see *DB2 v8.x* Info Center "documentation":http://publib.boulder.ibm.com/infocenter/db2luw/v8/topic/com.ibm.db2.udb.doc/start/c0011426.htm). In "version 9.x":http://publib.boulder.ibm.com/infocenter/db2luw/v9/topic/com.ibm.db2.udb.apdv.cli.doc/doc/c0023378.htm, the *DB2 Driver for ODBC and CLI* is "available separately, installed separately, and supports a subset of the functionality of the DB2 clients", therefore there's a way to limit DB2 Rails Adapter dependencies only to Ruby and CLI drivers (_some_ _restrictions_ _apply_, please consult "documentation":http://publib.boulder.ibm.com/infocenter/db2luw/v9/topic/com.ibm.db2.udb.apdv.cli.doc/doc/r0024160.htm).
