Hi Mihai,

While it may be relatively possible to have a 'limit my db size to' option, it would be very messy to start making assumptions about what data can stay and what data can go. It gets messier when it becomes possible other programs are the origin of the problem (i.e. "what do you mean someone ran (please don't!) 'dd if=/dev/zero of=/allYourDiskAreBelongToUs &' ? What a jerk!") causing behavior in the form of an ever-shrinking database.

It's definitely a part of server administration that isn't going anywhere soon.

Hi

I think this is probably something that the Wiki will address, but it would be great to specifically have a list of mango scripts (meta scripts) and examples in one place as a reference.

Yeah, JForum development looks pretty dead.

No feature to approve new users is odd. Though it sounds like it wouldn't be that hard to hack in... If you happened to know some java developers, that is :-}

Migrating to a new forum and SSO would be a pretty major exercise I expect so I can see the scope of the problem now.

Jeremy and Joel:

Thanks for the replies.

Jeremy: To reinstall, i exported the entire mango data base, using mySQL Export, then imported it into a virgin mango installation on another computer with mySQL Import.

I found the problem. At some time in the past, Mango created a table called datasourcesold which appears to be identical to datasources. When I created a new datasource, a new entry was made in datasources but not in datasourcesold. Then when I tried to create a new point, the difference btween datasources and datasourcesold triggered the error.

I copied the newly created datasource record from datasources to datasourcesold. Then the new point was created wih no problem.

I'll be testing this extensively before going forward.

Again, thanks for the responses.

Testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property

As a mater of fact there is. The first step to creating a new UI is to have a full API for Mango that will allow UI designers to easily exchange data with the backend. We are working on this right now and should have version 1 available soon. Version 1 will have limited features but will get things started and then we will add in the rest of the needed features as we go. This will allow the UI to be completely decoupled from the backend which has several benefits including easy theming and also hosting on separate sites, the development of mobile apps and many more exciting things. Redoing a new UI is a huge and expensive undertaking so I'm expecting it's going to take some time. The method and technology we will use will allow for customization and also the creation to 100% custom UI features using the API. The API will be released in stages but we will certainly be interested in feedback and use cases.

Sincerely,
Joel.

This is definitely a good idea. Documentation has been one of those things we keep working on but never gets finished as much as we want. Right now the wiki you found is purely a collection of the identical help documents you will find in Mango when you click on the "?" for the popup. I think in the near future we will implement a better wiki and maybe take you up on your suggestion to encourage others to help up with the documentation process.

Thanks very much,
Joel.

I've been playing with Dallas one wire sensors etc for sometime as they are reasonably cheap. The end plan is to control the house heating system intelligently. Currently we have a standard two zone system with a boiler.

WOW!!!! Long time since I've been to his site. Here is the situation. I personally would not recommend SCADABR anymore. Mainly because they are unresponsive to English users. Unless the new Mango does not have features you are looking for, I would stay away from SCADABR. Having said that, they are very active in their development and may have features that Mango does not have. It's been a while since I looked at either new versions.

I still use SCADABR on a Fedora 13 server. Back then they had a script instead an install file for Ubuntu. I was able to modify the script to get it to work on Fedora. I sent it to SCADABR and as I said, they were very unresponsive and as you can see they moved to Ubuntu support only. This does not mean it will not work on just about any Linux box, becasue all you have to do is create a Tom Cat Server and get the WAR files installed and running on the Tom Cat Server. Make sure you get the Environment variables correct too and you should be good to go. To get the WAR of the latest SCADABR, create a virtual Ubuntu server on your Centos and install SCADABR. Then you should be able to study the install and figure out how to transfer it to Centos. That is the best advice I can give you, the rest will have to be up to you. As I said, I would probably steer away from SCADABR.

The other option would be to install it on Windows. They have an incredible installer for windows. It is a breeze. Although I completely understand if you do not want to deal with Windows and all it's License complications. I know I don't, but it can give you a good idea if you think it is worth your effort to use over Mango. I typically install SCADABR on Windows first just to see the new features, which I have not done in a long while, because my server is set up and working fine, so I haven't installed anything in a year or two.

Good Luck!

I tried to export the "point hierarchy" and import right away. The port show up again. When the interval is extended to 3 minutes, number of the alert messages becomes less.

@mlohbihler said:

Found the bug. The fix will be in the next release. Thanks for pointing this out.

nice to hear that :wink:

Thank you.

Hi emdeex,

first mango is not open-source anymore.

@2 this is a special topic with special questions for special hardware, for special ... , so its better not to expect a vast community.

@3 You can assume ScadaBR as open-source successor of mango.

@4 this means huge effort without pay or benefit for the programmer, go and search for apache commons-math on YouTube, Twitter .... ;-)
But, YOU can change this.

Hi All,
I don't know if this is a bug or a normal behavior, if I set the "alias" field in a point change detector (with alarm information level), the email that came out from an email event handler doesn't contain any details about the change.
to be more clear:

(in thi example "ConfigurationChange" is my alias to a change detector of a point named "Configuration")
If I set the alias field the email body will contain:

[alarm info flag] - [alarm timestamp] - ConfigurationChange

If I don't set anything in the alias field, the email body is more verbose:

[alarm info flag] - [alarm timestamp] - Configuration has changed from XXX to YYY

is that normal?

Regards.
Fabrizio

Previous version hasn't this problem..
Isn't possible to return back to previous library version?

Regards

True, but "dp.getPointLocator().getDataTypeId()" to be specific. Thanks Arne.

Hi!
I've added a new user, after that I've added some data sources.
When I try to give that user access to the new data sources (in the "Users" page) I've got an error message:

PreparedStatementCallback; SQL [update users set username=?, password=?, email=?, phone=?, admin=?, disabled=?, homeUrl=?, receiveAlarmEmails=?, receiveOwnAuditEvents=? where id=?]; An attempt was made to get a data value of type 'VARCHAR' from a data value of type 'null'.; nested exception is java.sql.SQLDataException: An attempt was made to get a data value of type 'VARCHAR' from a data value of type 'null'.

The same message I've seen trying to change user password.

Sir,
I really appreciate the work your doing for developing this wonderful software. Mango m2m is amazing and I want to buy the complete version of Mango m2m2 and also want to know the details of long term Support from you, once i have purchased this software . So kindly provide me with the details.

Regards,
Srinivas.
