In our company we're using the Mirth Connect interface engine to interpret HL7 messages. For high availability we now need to move to a clustered setup, for which I'm reading this page. In that page we get an instruction to select the Applications menu like so:
I'm kinda puzzled here, because where does this application appear? I just have the Mirth Connect web interface and the Mirth Connect Java interface, but this seems to be a higher level system.
Could anybody help me out in where I can find this menu, or of what this screenshot is?
You are viewing documentation for the Mirth Appliance. This is an application that runs on the physical and virtual appliances sold for Mirth applications by NextGen. This requires an appliance license. Those licenses are generally sold with support contracts.

I have been trying to find an open source or affordable platform / CMS that is distributed.
And by distributed I mean that there is a single control panel with all the content, but you can have multiple websites on multiple web hosts that query an API that holds this content. Not the usual "one install, multiple websites" as you can do with Wordpress MU.
Ideally there would be an API that the website can connect to and get the data, or use push technology from the control panel once new content is added.
If there is no client side platform built but there is a sophisticated content management platform with an API that allows me to build my own client/website connecting to it, that would be fine too.
Does anyone have tips if there is such a thing?
Govento CMS is a distributed CMS, that allow you, to manage all projects with a single installation and present your content via push publishing dynamic and current on different remote delivery-platforms.

I am making a chat system and am new to xmpp technology.For server I am confused among ejabbered , openfire or tigase.I don't know erlang.And am good at java.
I am looking in a case where I have to change a user roster again and again everytimes a user logged in.And that too completely.So I am thinking to control user roster by myself and not by xmpp server.Morever I want to control what to do when a user went idle/busy. And many more.And for security it will be great if it can be done on server side rather than client side.
so how should I customize the xmpp server.And as I need to customise a lot which server should I use?Based on how easy its to learn them and customise them?
I have done similar kinds of customization in Tigase. I will recommend you to choose Tigase if and only if you are looking for high scalability . For Tigase scalability look at Scaling Tigase XMPP server on Amazon EC2 . The other part of Tigase is you need to dig into the code on your own there isn't much help available else than Tigase offical website.
In openfire you can get much community support in term of blogs and tutorials as compared to Tigase. But openfire isn't salable as Tigase. Also Openfire has a wide range of plugins available.
One more thing about Tigase is that Tigase maintains in memory rosters once user gets login.
We used Vysper (http://mina.apache.org/vysper-project/) as our XMPP server for custom clients, actually have it within an OSGi bundle so can hot deploy it.
It has needed some updates and XEP work when we needed something more detailed, but has been a great server to get started with.
I know this has been asked a few times, but there seems to be no clear answer ... am searching on this for the past 3 days or more.
There seem to be 2 ways to connect to an Oracle database from an iOS App :
ODBC Client
I need to compile ODBC (which ODBC?) using gcj for ARM. I think this is the hard way, wrought with errors, but possible with quite an effort.
USING WEB SERVICE
Connect from App to webservice and from web service to Oracle DB.
Are these the 2 methods available or any other?
Few questions on the two methods:
a. Which is more secure?
b. Will my company's security department oppose to any of the above?
c. Which is more performant?
d. Which of the above does one normally use?
Webservices are the answer, you do not want people connecting directly to the database from a mobile device. A Webserver will add one extra layer of security as well as the ability to handle simultaneous request without stressing the database directly
a. Which is more secure?
Webservices as explained above
b. Will my company's security department oppose to any of the above?
Yes, security department will insist not to open the oracle port to connect directly, unless they have it already open.
c. Which is more performant?
Webservices, setting up the right cache policies in a webserver can save resources to the database.
d. Which of the above does one normally use?
Webservices, because they offer you great advantages in security and performance, not only that, webservices are reusable and can be accessed by many different platforms, think on the future you might want to serve your application later on Android devices and Webservices will save you a lot of development time.
Many of today's top applications in the market use webservices, think about it.
Google Maps is a great example of how powerful webservices are!
It's not a good idea to connect to your database directly from your app. It can be secure if you create an account that can do nothing but SELECT, but there are some other things to consider.
Why burden the app with the Oracle client?
If you have many users you have to worry about Oracle handling a huge number of simultaneous connections. With a Restful API requests are stateless.
If you decide to change your schema. You'll also have to change your app. When you place a service in between, the app is no longer dependent on the schema.
ODBC connection will require that the Oracle port is open to the Internet, which in vast majority of cases will not be allowed for security and performance reasons. Even if it were, or even if you establish a secure VPN, a direct database access requires that the connection is kept open, which can be problematic when a mobile device can go in and out of the network coverage.
HTTP is far more tolerant to unreliable networks and can be encrypted using SSL (HTTPS). The problem with HTTP is that database do not have direct support for this transport so most people develop dedicated web services.
I work on a project called SlashDB, which automatically constructs RESTful APIs out of databases. For public APIs you would install /db in so called DMZ (a network segment between two firewalls) as described in this blog post.
SlashDB can be configured to allow restricted data access to public users or you can define specific users with varying privileges to data. It is designed as stateless service, which means that you can easily set up multiple nodes behind a load balancer and reverse HTTP proxy for high availability web scale deployments.
Regardless whether you develop the web service by hand or use our product you will achieve better scalablity, performance and security for your solution than by using direct client/server approach. I would even argue that REST APIs should be used internal enterprise data integration solutions but that's a whole new topic.
I am going to repeat what everyone else said, Rest API is the way to go. Do not connect to the database directly. However, there might be a way to connect to your database which I never tried my self.

We're currently using the SSO component of Oracle 10g App Server to authenticate users on our external / internet facing client "portal" (think similar to online banking)
SSO uses Oracle Internet Directory to store it's data, and we've been able to use PL/SQL and Java to access and modify the data held in OID (e.g create/drop users, change/verify passwords etc)
With the advent of 11g, Oracle appears to have "orphaned" SSO… it is available, but only as an add-on, and it appears to have been superseded by Oracle Access Manager. I'm guessing that it will have been dropped together by 12g. Plus it looks pretty difficult to install and get running correctly.
So, I'm wondering if anyone has any experience of having had the same migration problem as us? If so, what did you do?
Alternatively, does anyone have any experience of doing something similar using Oracle Access Manager? Do you think it will do what we want?
Or is there a better road to go down? Is there something else I should be considering?
Sorry for the very broad question, but it's one of those situations where a person's experience of what does + doesn’t work can make an enormous difference to us making some progress in a timely fashion. Thanks.
From my knowledge, Oracle Internet Directory (OID) is an LDAP compliant directory whereas Oracle Access Manager (OAM) is much more complex and consists of two main systems:
Identity System (users, groups,
workflows)
Access System (single/multi domain
SSO solution for Web and non-Web
based applications).
Access Manager relies on an Identity Server which is a stand-alone server process that communicates with any Directory Server (AD, OID, Sun Directory server..).
So you can use the new OAM and link it with your existing OID... to retrieve users/groups and metadata. All that you could do with OID will be doable with OAM as it brings more abstraction layers.
But in my opinion, and considering your case, directly accessing LDAP servers (OID, AD, etc) and using a light and "home made" SSO system is cheaper than relying on those big systems.... I think OAM is a usefull solution when you have lots of heterogeneous applications (web, non web, mobile, ...) and/or multiple organizations/domains with links and/or you need a very scalable approach.
I have requirement to develop DMS(Document Managemen System) with some initial requirements:
If possible DMS should be open source
Initially DMS should support up to 500 users
System should be scalable in sence od users or content
Docuemtns/Content should be stored on a file system
Document should be able to be marked for later destruction
Mandatory to have workflow capabilities
Mandatory to have version control capability
Nice to have SSO(Single Sign On) with Liferay portal
Nice to have posibility to expose some of funccionality via portlets in Liferay
Document management should be done via the web interface
Nice to have shared drive capability
Nice to have events and notifications about add/change content
At the moment I am in doubth to choose between Alfresco and Nuxeo.
I will appreciate any help to choose between them.
Thanks in advance
I have not much experience with Nuxeo, but here is for Alfresco:
1.If possible DMS should be open source
Yes.
2.Initially DMS should support up to 500 users
Yes, if you have a good server.
3.System should be scalable in sence od users or content
Yes.
4.Docuemtns/Content should be stored on a file system
Yes. Only metadata is stored in a database.
5.Document should be able to be marked for later destruction
The free Records Management module has retention capabilities.
6.Mandatory to have workflow capabilities
Yes.
7.Mandatory to have version control capability
Yes.
8.Nice to have SSO(Single Sign On) with Liferay portal
Yes.
9.Nice to have posibility to expose some of funccionality via portlets in Liferay
Alfresco and Liferay work very well together.
10.Document management should be done via the web interface
Yes.
11.Nice to have shared drive capability
Yes.
12.Nice to have events and notifications about add/change content
Not sure about this one. The Share module has this feature, but not sure about the main DM application.
Don't know the Nuxeo system, but we are using Alfresco as a document storage and session server. We have our own GUI and only use it as a back-end system. So far we had no problems. Plus Alfresco has a nice REST interface which makes it easy to integrate into any existing system.
