I'm starting with AmazonEC2 and created a security group with port 27017 open, but when I try to connect using "MongoClient" (java) I got the following output, can someone help me?
I'm also using Amazon Linux, and already tried to check to MongoDB documentation (https://docs.mongodb.org/ecosystem/platforms/amazon-ec2/)

Follow below my security group policies print screen:
Security group policies
Check your mongodb config and ensure that the bind IP is not set to 127.0.0.1 and listens to external connections
See if you can connect to mongo locally on that port
Take a look at this if the above two don't fix your issue https://serverfault.com/a/347272/269101

I am trying to connect to an oracle 12c database using the eclipse IDE but I get the error "Ping Failed!" every time I try to test the connection. I have tried to disable the windows firewall as some other similar post suggested it might be network related or the fire wall blocking it. I have the following settings:

Any ideas of what I am doing wrong?
Change your connection url to jdbc:oracle:thin:#server:1521:db. This will work.
I have followed the Bluemix/Eclipse instructions to setup the Liberty servers in eclipse. Able to do everything with the Bluemix/eclipse tools except for remote debugging.
Receiving the following exceptions/errors when I select the "Enable Debug Mode" on my application under the servers.
Tried a longer Debug timeout but that has not helped. Any pointers?
TIA

You need to ensure that you've done the following:
Enabled & configured the debug App Management utility as indicated here (1).
Ensure that dev mode for Eclipse Tools is enabled as indicated here (2).
Enable Remote Debug in Eclipse Tools as indicate here (3).
(1) https://www.ng.bluemix.net/docs/manageapps/app_management.html#Utilities
(2) https://www.ng.bluemix.net/docs/manageapps/app_management.html#devmode
(3) https://www.ng.bluemix.net/docs/manageapps/eclipsetools/eclipsetools.html#remotedebug
Do you happens to be using IBM JDK to launch the workbench? There is an existing problem that we are tracking on the debug support using that combination. If you happens to be using that, can you try using an Orcale JDK 8 to see if that resolves the problem?
The issue was with the JDK in use .... replaced the ORACLE JDK 7 with ORACLE JRE 8 and that resolved the issue.

The main causes of this exception - and the things you need to check - are:-
There is no network between your application (the client) and the server (the Box API). Where is the Box instance running, on same machine as your application (locally)?
What port is Box listening on? You need to show your connection code code (endpoint / port etc).
If client and server on different hardware, and you know you have a network connection between them then is Box behind firewall?
Hi
I am creating a web service and web service client in Eclipse IDE.
From the client I am able to access the methods of the web service, but when I write some code related to database( in the method of web service), I get Error that It is unable to locate the driver, But I have set the related jar file in the class path of the web service project.
After the above error I get the following Error:

Tell me please, why..? (I use MongoDB, Tomcat, Java)Thanks..
This is the type of error you should expect to see when load testing any web application with a tool like JMeter, and tells you that you're hitting the upper limit of transactions that the app can support... and this is where you'd do some tweaking of the settings to get better results.
The error message is saying that there are too many HTTP connections going at once and Tomcat is overwhelmed. I'm not sure which version of Tomcat you're on, but it looks like the default for Tomcat 6 is to queue up to 100 requests, then refuse any after that, and maxes out at 200 threads. Try increasing the "acceptCount" or "maxThreads" and see if that helps.
You may also try retagging the question, since this is a broader problem that affects more than just MongoDB apps... and you should get more replies that way. ;)
