Other processes (e.g. embedded servers) may open the same database simultaneously (hence the Shared). • Superserver (ThreadedDedicated) is also a single server process with threads handling client your version number, e.g. 5.0.0 or 5.0.1 If you’re running applications that expect the legacy libraries to be present, also create the following symlinks: Chapter 3.

Word document. Translation … The Russian sponsors, recognising that their efforts needed to be shared with the world-wide Firebird community, asked some Project members to initiate a crowd-funding campaign (UDFs) are programs written in an external programming language and stored in dynamically loaded libraries. Once declared to a database, they become available in dynamic and procedural statements as though user-defined BLOB subtypes. External functions for converting BLOB types are stored in dynamic libraries and loaded when necessary. For more details on BLOB subtypes, see Binary Data Types. 5.10.1.

Needs of the Access Layer Various database development libraries interrogate metadata, such as primary key, domain and similar structural information, in order is an open source product. If the encryption facilities were built in, or open source plug-in libraries were used, it would be feasible for users to build their own versions of the server or plug- in indeed, there are decompilers available to assist with this process. Once a person discovers what libraries your code was compiled with, isolating the results to only your own “secret” code makes the whole

defined in separate modules. Firebird ships with two UDF libraries: ib_udf (a widely used “InterBase library”) and fbudf. You can add more libraries, e.g. by buying or downloading them, or by writing them Testing for NULL — if it matters, elsewhere in this guide). The declarations for the shipped UDF libraries can be found in the Firebird subdirectory examples (v.1.0) or UDF (v.1.5 and up). Look at the files
