Success story : After NT4 death , firebird db started on another server

After the untimely demise of the NT server, I had to move the databases and the firebird server to a different computer. I had tried to do this before in December but was unable to connect from other computers on the network.

This time around, I noticed that I was getting a strange error message about temporary files; it turns out that the temporary file directory had been set to a directory which doesn’t exist. But more importantly, I still couldn’t get any computer to connect to the databases.

Servers that don’t want to die Farewell NT4 server: you served us well for 13 years and now is the time to say goodbye

The full goodbye in tears story is on this blog

The server worked admirably as a file server and as a database server (Firebird) until a few months ago when the first Windows 7 machines started to arrive. Win7 had difficulty reading the files on the NT4 server and even more difficulty in creating files. With regret, we installed another computer (originally Win7 but swiftly downgraded to XP) which served as a file host; the NT4 kept on working as the Firebird server.

You’ve heard the story about the servers which stopped working every night? When the support team came to find out what had happened, they found that the janitor had unplugged the electricity cable in order to plug in his vacuum cleaner.
This story may be apocryphal but something similar happened this morning. The noise of the computer annoyed one of the psychologists who was sitting in the same room, so she unplugged the server!  Instant death of the databases! We tried resuscitating the server but it kept on showing ‘MBR fault’ – obviously the master boot record of the server had been damaged. I imagine that someone, somewhere will know how to fix this, but we need those databases up and running now.

I’ve got the databases running on a temporary computer, but I will have to transfer them to the XP server. I tried this a few months ago, and whilst I was able to run the databases, I couldn’t connect to them from the Win7 machines. Now I have no option but to try again.

Farewell NT4 server: you served us well for 13 years and now is the time to say goodbye.

Creating access control into Lazarus + Firebird applications

This is a getting started article (written in Portuguese) from a series of articles related to Firebird and Lazarus
In the first part it’s explained how to install Lazarus and Firebird/Flamerobin on Ubuntu

I have been implementing the access control on my applications. It is a simple model, I have been “improving” since I started the program and always adapting to the new reality that has been presented. Not the last word on programming, but I believe it can be a good start for those who want to implement something from scratch.
