Oracle ODBC-Datenquelle in Windows 7

Um Oracle-Daten in Office-Anwendungen nutzen zu können, benötigt man in den meisten Fällen eine sog. ODBC-Datenquelle (DSN). In Windows 7 findet man eine Möglichkeit zu deren Verwaltung unter "Systemsteuerung", "Verwantung", "Datenquellen (ODBC)". Hier sind auch bereits vordefinierte Datenquellen enthalten (z. B. für Excel-Datenblätter, Access-Dateien oder auch Microsoft SQL-Server).

Um Oracle als ODBC-Datenquelle nutzen zu können, benötigt man den passenden ODBC-Treiber für die zu verwendend Datenbankversion. Diese kann man nach kostenloser Anmeldung im Oracle Software Download herunterladen nach vorheriger Registrierung.

Zum Erstellen der ODBC-Datenquelle muss eigentlich nicht viel beachtet werden, wenn man denn den richtigen ODBC-Treiber (richtige Architektur 32/64-Bit, richtige Datenbankversion) heruntergeladen hat. Das Feld "Data Source Name" bekommt den Namen, den die Datenquelle erhalten soll. "TNS Service Name" referenziert den korrespondierenden Eintrag der TNSNAMES.ORA-Datei und "User ID" ist selbsterklärend - der Benutzername. Weitere EInstellungen sind gewöhnlich nicht notwendig.

Aus persönlicher Sicht kann ich den Full-Client empfehlen. Der Download ist zwar groß (>1GB), enthält aber einen vollwertigen Installer, der viel Konfigurationsarbeit abnimmt. Er enthält auch den passenden ODBC-Treiber. Hier muss nach der Installation nur noch die Datei TNSNAMES.ORA angepasst werden. Danach muss man nur noch den Benutzer- System- oder Datei-DSN im Windows 7 anlegen unter Angabe der bekannten Oracle Benutzer- und Verbindungsdaten.

Pi And More 11 - QMC5883 Magnetic Field Sensor Class

A little aside from the analytical topics of this blog, I also was occupied with a little ubiquitous computing project. It was about machine learning with a magnetic field sensor, the QMC5883. In the Arduino module GY-271, usually the chip HMC5883 is equipped. Unfortunately, in cheap modules from china, another chip is used: the QMC5883. And, as a matter of course, the software library used for the HMC5883 does not work with the QMC version, because the I2C adress and the usage is a little bit different. Another problem to me was, that I didn't find any proper working source codes for that little magnetic field device, and so I had to debug a source code I found for Arduino at Github (thanks to dthain ). Unfortunately it didn't work properly at this time, and to change it for the Raspberry Pi into Python. Below you can find the "driver" module for the GY-271 with the QMC5883 chip. Sorry for the bad documentation, but at least it will work on a Raspberry Pi 3.

How to use TOracleConnection under Lazarus for Win64

Lazarus Programmers have had no possibility to use TOracleConnection under 64 Bit Windows and Lazarus for years. Even if you tried to use the TOracleConnection with a correctly configured Oracle 11g client, you were not able to connect to the Oracle Database. The error message was always: ORA-12154: TNS:could not resolve the connect identifier specified Today I found a simple workaround to fix this problem. It seems like the OCI.DLL from Oracle Client 11g2 is buggy. All my attempts to find identify the error ended here. I could exclude problems with the TNS systems in Oracle - or the Free Pascal file oracleconnection.pp though the error messages suggestes those problems. After investigating the function calls with Process Monitor (Procmon) I found out, that even the file TNSNAMES.ORA was found and read correctly by the Lazarus Test applictaion. So trouble with files not found or wrong Registry keys could also be eliminated. Finally I installed the Oracle Instant Client 12.1c - aft

Lazarus IDE and TOracleConnection - A How-To

Free programming IDEs are a great benefit for everybody who's interested in Programming and for little but ambitious companies. One of these free IDEs is the Lazarus IDE . It's a "clone" of the Delphi IDE by Embarcadero (originally by Borland). But actually Lazarus is much more than a clone: Using the Free Pascal-Compiler , it was platform-independent and cross-compiling since it was started. I am using Lazarus very often - especially for building GUIs easily because Java is still Stone-Age when a GUI is required (though there is a couple of GUI-building tools - they all are much less performant than Delphi / Lazarus). In defiance of all benefits of Lazarus there still is one Problem. Not all Components are designed for use on a 64 bit systems. Considering that 64 bit CPUs are common in ordinary PCs since at least 2008, this is very anpleasant. One of the components which will not be available on 64 bit installations is the TOracleConnection of Lazarus' SQLDB
