Firebird 5.0. The legacy connection method sends passwords over the wire unencrypted, does not support wire protocol encryption, and also limits Chapter 3. Installing Firebird 8 (truncates!) the usable length reachable from the client at all. At this point, it is assumed that you will use the TCP/IP network protocol for your Firebird client/server connections. Chapter 3. Installing Firebird 9 3.4.1. Pinging ib_util.dll $(install) Client connection libraries fbclient.dll (with an optional gds32.dll, to support legacy apps) $(install) (with an optional copy in %windir%\System32 — see note below table) Some

Local connections On Windows, both architectures now support safe and reliable local connec- tions, with only the server process requiring access rights to the performance in case of a small number of connections that do not influ- ence each other. No SMP support.

These SQL statement syntaxes provide better interchangeability with other SQL database products Windows Local Connection Protocol with XNet The transport internals for the local protocol have been reimplemented (XNET instead of IPServer). With regard to the local protocol, the new client library

performance in case of a small number of multiple connections that do not influence each other. No SMP support. On multi-processor Windows ma- chines, performance can even drop dramatically as the OS switches will be started automatically. The non-server Windows platforms – Windows 95, 98 and ME – do not support services. The install- ation will start Firebird server as an application, protected by another application assumed that you will use the recommended TCP/IP protocol for your Firebird cli- ent/server network. Note For information about using NetBEUI protocol in an all-Windows environment, refer to Chapter 6
