Delete JSC Lock Files

Posted on May 5, 2003 by qtzar

A while back I posted about how to change the Domino R6 service startup command so that it would automatically start with the Java Console support enabled.

I was just taking a quick look through the SandBox and I came across a handy little utility. When you start the Domino server with the Java Console enabled it creates a special lock file called .jsc_lock in the Domino data directory. Quiting the server normally will get rid of the lock file however in the case of a server crash the file will still exist when the server is rebooted and therefore the Domino service will not start.

So what is needed is something that will delete the .jsc_lock file before the Domino service starts. The easiest way of doing this is to create another service and make the Domino service dependent on it so that the Domino service won’t run until the new service has ran and removed the file.

Download the file from the SandBox

R6.5 Wishlist : During server installation have an option to ask if the administrator would like to enable the Java Console when creating the service and auto install this little addon if it is selected.

Making Money From Open Source

Posted on May 1, 2003 by qtzar

An interesting discussion has been spreading across some of the Domino Blogs since the London Developers Piss Up Meeting the other night. How can people make money from Open Source development?

As the number of Open Source projects for Lotus Domino increases there does come a point when somebody will want to start making money. As Steve Castledine mentions in a response on NotesTips, Open Source doesn’t pay the bills.

Steve has jumped onto one of the many ways of making money from open source software by splitting the license agreement so that personal use and non-profit organisations can make full use of his offerings without having to pay a license fee while commercial companies that make profit would have to pay a fee. The only issue with this is hoping that commercial companies will make the payments and not just use the software without paying.

Another way of making money from open source software is not by selling the software but by selling the service and support that goes along with the software. Take the OpenNTF mail template for example. If you have a big customer who is using ND6 why not show them the mail template. Show off the features. Sell the IDEA to them, then when they buy in charge them what ever it takes to roll out the product within their environment. Then charge them again for supporting it.

The same can be applied to BlogSphere. If you know a company that needs a website and you think BlogSphere can fit the bill then sell them the IDEA and then charge them the time it takes to configure the template to suite their environment. Use it as a base point for a new application. Use the ideas for developing a customised application. The main point is your not selling the template itself, your selling the service and support.

Don’t think it could work… Look at Linux. It is an open source OS. Go to RedHat and download it for free. No Support No Help. Yet their Enterprise server edition can cost upwards of 800 dollars for the software, printed manual and service and support.

That is how we make money from Open Source Software.

Exam Fever

Posted on April 30, 2003 by qtzar

Joe Litton is not the only one
doing exams these days.

Today I sat the ND6 Administration Upgrade exam and the Lotus Workflow 3 Development exam. Both exams were passed with ease. This means that I am now an R5 CLP, ND6 CLP, R5 CLI and ND6 CLI for the administration track and a CLS on the collaborative Solutions development track. I am already a R5 CLP on the development track. I must sit the upgrade exam for that soon.

Tomorrow I hope to do the SameTime 3 Admin exam and the QuickPlace 3 Admin exam.

LotusScript Posters

Posted on April 29, 2003 by qtzar

Whenever I’m working with LotusScript I always have my reference posters on hand to do quick lookups of classes and their methods and properties. Now with ND6 the LotusScript chart is built right into the Domino Designer’s hoome page but I still like to have the full sized chart on a nearby wall.

If you have upgraded to ND6 and you want to get your hands on the new revised wall charts then you can download the pdf format of the charts from the Lotus Developer Domain documentation site. The ND6 charts look a bit different from the old R5 charts. The LotusScript chart has been split into two seperate charts and there is now a new Formula Language chart as well as an updated Cobra / Java chart. The LotusScript charts also show what methods can and cannot be used via COM. Well worth the download.
