I use Nhibernate in a windows application. at run time I close the form and then i change the data in Db manually so after opening the form, it shows the old values instead of new entered values. it shows new values just when i close all program (killing process) and start application again.
this question was already asked by Kristoffer but there was no accepted answer for that.
please lead me to solve this problem.
thanks
You should read some texts that explain how the NHibernate session (first level cache) works, otherwise you will get big problems using it.
To me it sounds like you are keeping a session around for longer than needed. I would recommend the following article, it is essential reading for anyone creating a winforms application using nhibernate.
MSDN Magazine - Building a Desktop To-Do Application with NHibernate
On a windows application you should be using session per presenter.
This SO Question has some good answers that might provide you with a solution.
Also a good Google phrase is "session per presenter"
The NHibernate cookbook also has a good example (although you will need to pay for this)

I'm working on a couple of million records, as soon as I try to run an advanced find, and put as a criteria a linked entity, the advanced find goes in timeout.
Create custom views on this allows me to filter properly? Anyone knows the proper way of using the advanced find this way? Are there limitations on the out of the box CRM that i should be aware of?
In CRM 2013 - it is possible to add indexes for specific fields by adding the columns to the quick find view for the entity.
You will need to wait for the Indexing Management Job to run (which is run every 24 hours by default) - see http://blogs.msdn.com/b/darrenliu/archive/2014/04/02/crm-2013-maintenance-jobs.aspx.
In previous version of CRM, it was necessary to add the indexes directly to the database - this may be necessary for more complex queries.
was too early to post an answer. The problem that I encountered was related to the OOB advanced find. Looking for example for an account with some related contacts (a really plain search with a linked entity) i had a SQL timeout. Everything was OOB so I was a little bit clueless and I opened a case to Microsoft. They found a bug, if i was changing the sorting the advanced find started to work again. They are still investigating. So wasn't a setting problem but a crm bug.
I am facing issue with my xpage application. It works perfectly fine with less number of concurrent users. But When more concurrent users say more then 1000 , try to access xpage application, It becomes very slow. I have looked the code and corrected some redundant code .
But I am not sure this is the issue. For that is there any way in lotus notes to simulate the load testing with 1000 users?
Please help me if any workaround there.
Agree with Oliver about using JMeter.
But then what you really want is to find out where you have "expensive" code. For an agent you can just "profile" it. However, that is a little less straight-forward for an XPage. You can try the XPages Toolbox from OpenNTF.org. I have not tried it on Domino 9.0.x but I would think you could use it.
Another simple (and quick) way to get an idea is to print some time info on the console of the server when you load the pages in your application. You can use a phase listener to add this information - or put it in another more specific location - it really depends on the way that your application is structured. But this way you can get a very quick idea of where the bottlenecks are before you dive into something like the toolbox :-)

We used JMeter to get an idea what will happen if X users will access our app in Y threads etc. http://jmeter.apache.org/
After using youtrack for quite a while my organization is considering a move to JIRA (because of many reasons). However JIRA doesn't seem to include a youtrack importer/migration out of the box (though there seems to be plenty of importers/migrations the other way around).
Has anyone migrated from youtrack to JIRA and have any experience in this?
Edit:
To anyone who might have this problem later, my final solution ended up something like this:
transfer all "basic" data by hand (user accounts, basic project setup etc)
write a small C# program using the atlassian sdk and the youtrack sdk that transfers from one to the other (creating empty placeholder issues if issues was missing due to someone deleting them in youtrack in order to keep numbering).
This approach worked good enough and I managed to transfer pretty much all data without any loss of any very important data (though of course all timestamps are messed up now, but we saw that as an acceptable loss).
Important to know is that youtrack handles issues moved from one project to another a bit counter-intuitive (they still show up in their first project even when they're moved away from there, but they have an issue id from their new project - a slight wtf when I ran into that the first time).
Also, while the atlassian sdk did allow me to "spoof" the creator of an issue (that is, being logged in as used A and creating an issue while telling the system that it's actually user B who is creating this issue) it does not allow you to do this with comments. So in order to transfer those properly I had to actually loop through the comments and log in with the corresponding new user and post the comments.
Also, attachments from youtrack was a bit annoying to download, so I ended up having to download those "by hand". :/
But all in all, it was relatively pain-free. Some assembly required, some final touch-ups required, but it was all done within a couple of days.
I had the same problem. After a discussion with JIM (Jira Importer) developer, I used YouTrack Rest API and Python script to make JSON files. Then I used JIM JSON import.
With this solution you can import almost all fields from YT - the standard one and files with description, links between issues and projects and so on...
I don't know if I can push it to GitHub, I have to ask my boss - I did it during my work hours.... But of course you can ask me if you want.
The easiest approach is probably to export the data from youtrack into CSV and use the JIRA CSV importer. You may have to modify some of the data to fit the expected format for the CSV importer
I am trying to view my sagas in the RavenDB management studio, and loading even the initial page, all that I see is this "Querying documents..." box with a continuous moving progress bar. I can not seem to get past it, going from page to page it does not go away. Is there a way to pull all of the saga data into a list so I can look at it? It appears the issue is that the saga documents are continuously being added.
I've looked into the HTTP API and the Linq adapters, but I guess I am looking for something that already exists that can easily peer into the server much like the silverlight studio, except not such a pain. I more or less just want to pull a snapshot of all the documents into some kind of readable list.
I find LINQPad 4 convenient, the RavenDB driver for LINQPad can be found here:
https://github.com/ronnieoverby/RavenDB-Linqpad-Driver
For the command line - cURL using dynamic indexes as explained here:
http://ravendb.net/docs/http-api/indexes/dynamic-indexes
In the browser, go to http://localhost:8080/docs
You might need to install JsonView, but that should give you what you want.
If anyone wants to know how to browse the data through REST call,
"localhost:8080/databases/{database-name}/docs/{dataset-name}/id"
example:
"localhost:8080/databases/testDB/docs/Sites/1"
will give the json data for the "Sites" document
"localhost:8080/databases/testDB/docs/"
will give the json data for all the documents in
testDB.
What is the process to access data from a SQL data source and have it fill in a list box control so that the user may select one of the values?
I have been given the name of the database and server, the login ID and password.
Code samples would really be appreciated as I have never done any SQL coding.
The latest Extension Library on OpenNTF ( extlib.openntf.org ) has a whole bunch of Relational Database extensions.
You'll need to get the JDBC drivers for whatever SQL server your going to be accessing and then take a look at the ExtLib demo application on how to create the JDBC connector from your application. Once the connector is in place you can then just the new controls in ExtLib to easily create a view pane etc.
You will also need more then the SQL server, username and password, you'll need to find out the different tables that you'll be accessing so that you can reference them from your Xpages application.
I've created a video showing JDBC access from XPages: http://www.youtube.com/watch?v=p6oRCsTsVqc
Wait for the book that will e released soon about the extlib. I know Jeremy hodge wrote the chapter so you might be able to get some info from him.
From an answer I gave earlier: you might want to check out the blog post announcing the JDBC support . It has an excellent video explanation and a link to a slide deck.
Also, take a look at Xpages101 lesson 61. It's paid-for content, but well worth it if you're serious about Xpages development.
If you want to combine Upgrade Pack 1 (UP1) with the Extension Library JDBC parts, then make sure to use the Extension Library that matches exactly the UP1 version. This is version 853-20111215 of the Extension Library. Then you can use the update site method to only deploy the experimental parts of the Extension Library (com.ibm.xsp.extlibx.feature_8.5.3.20111215-0914.jar).
For newer releases of Extension Library things might (will) have changed so that UP1 and Extension Library can not work together.
When UP2 is released, you need to remove the Extension Library package and deploy UP2. At that point in time UP2 might contain the JDBC support.
Roy,
As the previous posters put the ext library stuff will make it a little more "Drag and Drop", but you can use regular JDBC connection to get the data you want, Its pretty simple, but a lot more code than using Domino as a backend. You might want to look at this John Mackey blog post about doing a very similar thing...http://www.jmackey.net/groupwareinc/johnblog/johnblog.nsf/d6plinks/GROC-7G9GT4
Keep in mind that you need the actual ext. library for this. The upgrade pack does not contain the JDBC stuff.
Edit:
Keep in mind that if you don't need "LIVE" data access, and the information you want is fairly static you could always just use a lotusscript agent to pull the data down into Notes Documents. Run that once a day or whatever. No fancy XPages stuff needed. That's fairly common coding and practices with examples available.
Then just have the list box pull from the documents you brought down.
