Application Servers

An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.

Hi EE,

We have an application that dependent on a user session being one of our Windows 2003 servers. If we log out or even minimize the session multiple interfaces (msg queues) of the application shutdown, could anyone give me some insight as what is going on here and how to resolve.

An odd issue any assistance in welcome.

Thank you.

I have a Warehouse Management Systems running on window server 2008. It seem slow accessing the WMS at times and I don’t see any issue with the network.

I run Wireshark on the network and see everything is working just fine and run continuous ping using ping plotter show latency within 4ms Avg.

Asking if anyone has any idea on how isolate if the issue is with the WMS application, window server itself or some services on the server that causes the issue.

The window server is hosted on VMWare with 8vcpu and 8gb ram

Are the following Application Servers Cloud Native?

1. Websphere Liberty
2. WildFly/JBoss Application Server

I mean without their native(IBM/Red Hat) Cloud offering, whether these two could be
considered similar to Node.js/Cloud Native?

Hi All,

I am doing some housekeeping on application servers I am responsible for.  All applications are working fine I just want to free up space on the drives.

Having come across the WinSxS folder which I know is very important and should not just delete files as I could quite easily break the server or applications.

I was going to start with a simple disk cleanup but discovered this is not installed as standard on Windows Server 2012, it need to be added as a role then requires a reboot which I'd rather avoid outside of the monthly scheduled reboot.

What other options do I have and how do I know which files can or can't be deleted?

I have a customer who is wanting to ensure his staff can't take any data with them.  We can lock down USB devices (Thumb drives, Hard Drives, etc), but he's now concerned about them accessing things on the server and getting them off by using web mail clients (Yahoo, Gmail, Hotmail, AOL, etc) or file sharing sites (Dropbox, OneDrive, etc).  Short of blocking access to these sites (which would be a pain), is there any way to restrict their ability to steal his work?  And, if so, how difficult AND expensive would it be?

Failing that, is there some way of recording access so we can tell that John Doe accessed these 275 files today, and he was only supposed to be accessing 100 of them?

We're in a workgroup environment at the moment, switching to a Server 2016 AD domain.  All users are local admins on their workstations (Windows 7 and Windows 10).  A lot of the people in question will likely have to REMAIN local admins due to their software (AutoCAD, Quickbooks).

Please feel free to ask any questions for me to elaborate.

MacOS Sierra plug-in configuration a qualified success.  However, I have no CFB perspective.
Install log says:
Installation: Successful with errors.

Non fatal errors being two occurrences of
Modify Text File - Single File:   /Users/barrygbrunning/eclipse/java-oxygen/Eclipse.app/Contents/Eclipse/Eclipse.app/Conten ts/Info.plist
                          Status: ERROR
                          Additional Notes: ERROR - Unable to locate ASCII text file to be manipulated. Deferring...
 
Indeed there is no such file, whereas there is a file /Users/barrygbrunning/eclipse/java-oxygen/Eclipse.app/Contents/Info.plist.  At the install log errors referenced path /Users/barrygbrunning/eclipse/java-oxygen/Eclipse.app/Contents/Eclipse/ are located folders: configuration, droppins, features, jre, plugins, readme and the eclipse.ini file, but no info.plist.
 
The implied "Deferring..." action seems to have not happened.  Any suggestions as to what I might do to recover the situation?  What should have happened to an info.plist somewhere? How might I get the CFB perspective to manifest in Eclipse?

I am in the process of getting an outdated server upgraded to a supported OS. Running VMWare 5.5 and we get getting a system off a Virtual Server 2003 x86, and upgrading it to the only available system possible a virtual Server 2008 x86. The original server is an application and file server. It has 3 IP addresses assigned to a single nick and the DNS has 2 of those IP's assigned to static FQDN's.
Here is where things get unusual...

When the original server is the one bound to the domain I can ping it from all of my systems. When the new computer is bound to the domain it will not respond to ping from only certain subdomains (inbound ICMP v4 & v6 are enabled for file and print sharing.. so it isn't the firewall).

The 2nd and 3rd IP's do not respond to any type of ping even though they show they are connected to the network. I have even tried changing the configuration by removing the 2nd and 3rd IP's from the one nic and giving them their own individual nic cards to see if they might respond from there. Again no such luck.

I am going crazy trying to get this to work properly but I can't seem to find a way to get the nic's to talk correctly, nor can I get them to respond to all of the subdomains that the original server had no issues responding to.

I am hoping that someone may have seen something like this before. I realize that an in place upgrade doesn't always resolve all issues but I've never seen something like this in any previous attempts.
Thank you in …

we have direct printing with two application servers running IIS connecting to  SQL DB . we have upgraded two application servers  3 months back and one application is not responding for direct printing .
our application vendor is asking us to check with the network team to resolve the issue  . but it seems to be nothing wrong with the network level .

Q1  - How can I confirm the network level issue is  clear - Eg by ping the client to server or  ?
Q2 -  Patch level , there are some changes in the patch level  , but our vendor has confirm before the patch upgrade ,there is nor issue with the latest patch update .

Our Printing is configured as below
Client end  - connecting the receipt printer to client PC  - Host name  - C1
Application server side  -   Direct printer is mapping    billingPrinterC1 and billingPrinter is the  prefix for the printer profile name for billing Dep.

billingPrinterC1   IPaddress

how can I rectify the direct printing issue on the not responding server .  Direct printing still using for big applications ? we are having so much of issues with this architecture . please comment on this
 I will share some testing result later

How can I use RDP (MSTSC.EXE) to log on to server as if you are at the console? I am looking for a way to modify the .RDP so when I execute the remote desktop to a server, the login page is pulled up so i can type my credentials in or use a digipass (vasco) alternative. I also use HP RGS to get into servers and blades, but the version in my environment is buggy and needs to install a client ... but it does accomplish the type of login behavior I am looking for ... when it works. I know that the .rdp file can be modified with a text editor, but I have not had any luck with the settings I have.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Using an Oracle Data Guard with a Primary and Standby database instance, is there a way to use a JDBC driver to send to the correct DB instance (or more specifically, to allow the application to fail over to the Standby  database instance if the primary is down)

I examined the documentation and the JDBC drivers appear to be for a RAC cluster as opposed to the Data Guard Primary and Standby

Can some one please help clarify ?

Thanks

Cloud based application having issues with ldaps bind to our Domain Controller in DMZ.
The application vendor is seeing the follwoing log entries on their side:
           [7:Public User][1024:application notice][R] (:) - Unable to bind to the LDAP server.

Based on this they have taken a wireshark capture and seen the following sequence of packets:-
Source -> destination (DC)   TCP    49662->636 [ACK] Seq=805 Ack=12910
Source -> destination (DC)   TLSv1  Application data
Source -> destination (DC)   TLSv1  Encrypted Alert
Source -> destination (DC)   TCP    49662->636 [FIN, ACK] Seq=927 Ack=12910
destination (DC) -> Source   TCP    636->49662 [ACK] Seq=12910 Ack=928
destination (DC) -> Source   TCP    636->49662 [RST,ACK] Seq=12910 Ack=928

They are saying that the reason packet analyser highlights the [RST, ACT] packets in red is because after the connection closure by Cloud Application server (source) [FIN, ACK] , server is expecting a final [FIN, ACK] from Domain Controller  (destination) but [RST, ACK] arrives instead. And thus they believe that it could be a issue with the Domain Controller.

Is this claim correct?
What can we do to troubleshoot this further?

App Development

Apart from its culture, demographics, and beliefs, Indian infrastructure is also quite complex, especially because of the challenge of overpopulation that stares us right in the eye. Due to this, it has been quite difficult to anticipate the traffic behavior, directions, local businesses, and many other things, with accuracy. When Google Maps was launched in India, it certainly helped, but also showed us that we need a better solution. Something that is indigenous, so that it knows the country inside out. Hence, MapMyIndia.


A mobile apps development company that works in sync with ISRO’s Bhuvan satellite - MapMyIndia recently launched its navigation and positioning app, created exclusively for India, and is already giving tough competition to Google Maps. It provides accurate information even for daily commuters. In fact, it has taken it a step further by including many live features that are extremely helpful, especially when you are in a country like India where traffic situations and even addresses change every now and then. So let’s take a look at what features it brings together to create something that is messing with the Google ‘bear’.


IoT Tracking


A big leap ahead for India with this IoT solution, the app uses its own IoT devices to track and collect information from different points through sensors. Making the best use of IoT technology, the app has been instilled with the ability to create real-time alerts for users and commuters. In case of a traffic jams, IoT sensors take note of the situation and suggest short and alternative routes to mitigate the traffic.


Voice-guidance


Matching shoulders with Google, the app also provides a voice navigation facility with turn-by-turn navigation support, which is expected to decrease the rate of road accidents that happen due to the lack of hands-free GPS systems.


Floating button for Reporting Issues


Apart from the data collection via the IoT system, there is a manual way of reporting issues i.e via people. Road damaged? Broken transport? Traffic jam in your area? Just take a picture and upload it to the relevant section in the app. Good thing is that the app has covered almost all kinds of issues that occur, including map issues, traffic issues, connectivity issues, and areas with specific access.


Tailored for India


Compared to Google Maps, MapMyIndia focuses on much more detail and list small businesses, facilities, shopping centers, and even personal addresses. However, because the app is still quite new to the market in terms of reach, it is still under the data collection phase, during which you may not find many small addresses in the app. But that is only for now because the database is constantly growing.


Detailed Information


Another reason why the app has great usability in India is that it provides complete information about a particular thing that you look for on the map. Apart from the address and direction, you also get a contact number, email, website and opening hours. Also, with the help of worldview, not only you can get details about a place, you can also see what people think of this place, based on the number of likes it has garnered.


Analytics


Some people just want more information about everything, including trips, so just an odometer and tachometer is not enough for them. MapMyIndia comes with trip analytics that allows info savvy people to track more. You can track the time of trip completion, estimated time of arrival, remaining distance, remaining time of arrival, and much more; on-the-go.



MapMyIndia has created something that is perfectly tailored to the ever-changing maps of India. However, one of the things that the application clearly lacks is user experience. The touch buttons and screens reflect subliminal efforts on the designing side.

I have Tomcat 8.0.35 running, web application running from IntelliJ IDEA 2017.3.3 (build successful and WAR deployed) but the browser (I tried with Chrome, Firefox, and IE) is showing HTTP Status 404 when I try to access http://localhost:8080/ or http://127.0.0.1:8080/.

I built my web application with Maven as WAR. The WAR file was successfully deployed in Tomcat's "/webapps/ROOT" directory and "index.html" and "index.jsp" are there and at the end of the deployment the browser page is open.

Tomat is configured to default ports: 8080, 8081, 8009.
