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.

My colleague got the attached error last month back when trying
to download Sparc Solaris 10 patchset : what's the reason?

Didn't try to download the patch for Solaris x86.  Does the support
contract we have with Oracle makes any difference if it's Sparc or x86?
Or the patch is simply old & has been superseded with a new one?

Experts,
 We have 2013 sharepoint farm. We are planning to implement SSL (http to https) to our web application. We have 4 front end servers , 6 Application servers. We would like to know what is the advantage and  dis advantage to implement SSL on back end server or Load balance? Also we are planning to migrate our Sharepoint 2013 to Office 365 so what is the common practice to implement (server or load balance)?

Hi EE

I'd like to configure SSL for JBoss EAP 6.4 in domain mode.

Hello - I am running SharePoint 2016 and I've been task to setup a way to have external access to SharePoint.

Front-End Servers = 2 Servers
Distributed Cache Servers = 2 Servers
Application Servers = 2 Servers
SQL Servers = 1

What I have read is that the best practice is to leave our SharePoint farm entirely within the Intranet and use a reverse proxy in the DMZ, like WAP + ADFS. We’ll need to open far too many ports between SharePoint and Domain Controllers which will reduce the security of the environment. A reverse proxy is a single port -- tcp/443.

I am looking for a step-by-step guide on how I can set this up for SharePoint. I truly appreciate your help!

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?

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.

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.
