The drivers are ODBC API-compliant dynamic link libraries, referred to in UNIX and Linux as shared objects. The prefix for all 32-bit driver file names is iv. The prefix for all 64-bit driver file names is dd. The driver file names are lowercase and the extension is .so, the standard form for a shared object. For example, the 32-bit DB2 Wire Protocol driver file name is ivdb2
nn.so, where
nn is the revision number of the driver. For drivers on HP-UX PA-RISC only, the extension is .sl, for example, ivdb2
nn.sl.
