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.

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.

We have an application server that is mission critical. Is it possible to create a backup of the server, where everything is identical including the IP Address, that works on something like a heartbeat and only comes online if the other server goes down?

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

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.

I keep seeing this error message on two 100% identical (same hardware ProLiant DL380p G8, 8 GB RAM on each, same 2012 R2 o/s, same updates) servers that are currently
doing nothing and have nothing else installed in terms of roles and
features except file server. No Exchange, no DC, etc.
Both are physical servers (NO virtualization running on them) on the same network in the same AD domain as all other servers that do not show this error
They both have Shadow Copies enabled and configured for previous versions of files/folders,

We are deploying Web application proxy server in AD FS environment. We will use this ADFS to configure Azure AD Connect for Exchange Hybrid Environment.

Question:   For above mentioned environment, Web Application server should be part of domain or can we keep it as stand alone server?

If it should be part of domain then what ports should we need to open to allow its access to DMZ domain controller servers ( active directory)?

I program in C# but need to write a Java app that can be downloaded and run on many platforms. The application will "scrub" confidential information from a merchant's credit card report (PDF).

It will remove the merchant's name, address, merchant ID (xxxx-xxxx-xxxx-xxxx) account number, etc.

It will do this by scanning the entire PDF and exporting non-confidential data to a CSV file.

I need this to be easy for non-techies to download and run.

What basic considerations should I have about what I should and should not consider before I start planning the design?

What frameworks help? Hurt?

What kind of installation program/script is needed?

I would host this download from my website...

Thanks.

Is there a nice tool that can retrieve all folders in a certain directory that have a .v1 or .v2 folder extension (not file extension).  I need a list so I can delete those directories instead of manually doing it.  If anyone finds a tool or command that can do this, thank you!

I host application servers for a website and to allow users to upload documents, we need them to be scanned first by AV software. I assume I will need to find AV with some sort of API to trigger the scan. Does anyone know how to approach this problem?

EE,

I'm having issues getting our network devices to work with SNMP v3 and there's not much online in the way of troubleshooting v3.
I went ahead and switched to v2 just to see it work and does show up as healthy now, however, it doesn't appear to pull any CPU/Memory or interface data even though it shows CERTIFIED and enumerated the Vender as PA-5000 series. The Network Summary view shows the interfaces with a green empty circle as if it's not being monitored. Firewalls are obviously fine since it enumerated the OID Tree and discovered everything.

Do we need SNMP port 162 in addition to 161 or could this be another issue?

Hi Expert,

One of our development team were trying to loading the data in their test database from their application portal.

They can attach file into the database but they got the following error.

"Timeout during database update. The operation has been accepted by the server and will usually complete successfully."

They are able to load the file successfully but don't want application user to see this.

Here is my question, is there any option to set up timeout for the database level. They set up the file size from application side only for 20 MB


Please help
