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.

I have to draft a guideline for systems that interface with a CII system & need inputs:
currently, the interfaces concerned are limited to 3 types only:

1. files transfer
============
I can only think that the generally practices ie:
 a) encryption of data in transit (eg: using sftp instead of ftp/mapping a drive or NFS)
 b) encryption of data at rest if it's sensitive (tampered with)

2. API
=====
how do we secure these (in particular APIs using microServices)??
I've heard of API needs to be certified so before requesting for it, need to be certain
else applications developers may question its relevance/usefulness

3. DBLink
========
Those sqlconnect  esp Oracle links to extract / update data.
Will need to define if the non-CII system is
   a) updating into CII, will have to be extra stringent but how?
   b) extracting from CII, just encrypting the sql calls
 

Oracle databases, weblogic are involved in the critical systems
while the less-critical systems may be Windows, Linux on
various apps (including mobile apps).

Editing thread to add Oracle as it relates to DBLink.

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.

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

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?

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.

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!
