Applications written for DB-Library versions 4.x, 10.x, 11.x, and 12.x must be recompiled to use DB-Library version 15.0.
DB-Library 12.0 and later
is non-reentrant and does not use native threads. You cannot use DB-Library 12.0 and later with an Open
Server that uses multithreaded or reentrant (*_r.*)
libraries and that runs on any UNIX system.
