I need help in the following situation:
I have two WebSphere application servers and WebSphere HTTP server.
I need to do the following:
when a request failed or (get timeout) on one server , Http Server do not foreword the request to the other WebSphere Application Server.
thanks.
That's a complicated process, not easily explained, there are so many things that could be wrong. Have you started with the WAS Admin guide? It has walkthroughs on this proceedure. Find it here: http://www.redbooks.ibm.com/abstracts/sg247615.html?Open

I researched about any plugin/module WSGI for Oracle WebLogic 12c that allows me run a python flask app, with no success.
The reason for why i need to run from WebLogic 12c, it's because i need to use the SSL certfied living there.
Researching, i found many web server (Apache, Gunicorn, etc) can act as proxy of WebLogic, here is an example, where Nginx receive all the requests with SSL and then passed them to WebLogic:
https://medium.com/#Dracontis/nginx-as-proxy-for-weblogic-with-ssl-c7e1076e2c0c
So, i wonder if there is a manner to invert this order? I mean, WebLogic receive all the requests (safely because of SSL certified) and then pass them to any web server with the WSGI standard.
Thanks in advance.
I didn't find a sort of solution that accomplished the topic above. However, in case someone needs implements this topology here is what i did:
I've installed an Oracle HTTP Server (OHS) and creating a wallet for the SSL certified, in certain way in which the OHS can receive the requests secure, then inside the OHS with specific setting achieve forward the request to the Apache running with the module WSGI.
I have to check the connectivity to the portal which is behind the WebSeal Server. I need the response code of the actual server and WebSeal server code too. Please help me.
Try turning on debugging. Ideally, you are the only traffic on the server. Make sure to turn it on before you do anything that may be related to the problem (i.e. logging in) then wait at least 1 min after the problem occurs to let the logs catch up.
server task default-webseald-xxxx trace set pdweb.snoop 9 file path=c:/pdweb.snoop.txt,rollover_size=100000000
server task default-webseald-xxxx trace set pdweb.debug 9 file path=c:/pdweb.debug.txt,rollover_size=100000000
Make sure to turn it off afterwards as it will destroy your hard drives.
server task default-webseald-xxxx trace set pdweb.snoop 0
server task default-webseald-xxxx trace set pdweb.debug 0
WebSEAL constantly checks the backend servers within the junction. If you use pdadmin to do server task SERVER show /junction you can see if the backend server is online or offline.
I am assuming you mean HTTP response code. You can get that from WebSEAL by doing a simple HTTP/S get like you would any regular HTTP server. However, for the backend server, you will need to go around WebSEAL and connect to the backend directly to perform your checks.
If you are trying to setup monitoring, you can do one of two things. Either watch the msg__webseal-default.log for the following lines:
DPWWA2025W IBM Security Access Manager WebSEAL has lost contact with junction server:
Or you can use the server task command to show the junction and look for the Server State: being running or not running.
I'm on Weblogic AS 10.3.5, I have two managed servers pointed to a cluster, so I have two url, one for the first managed server, the other one for the second.
I will deploy my application on the cluster, so will I reach it on both the url? will the application deployed and running on both the servers?
How does it work? Can you give me some references, please?
Is it clear?
Thanks a lot!
First, you shouldn't be using WebLogic 10.3.5 anymore since it has reached the last stage of support called Sustained Support. Consider to upgrade at least to WebLogic 10.3.6.
Related to your question, I believe you are talking about a Web Application and how to access it. First you need to read about Load Balancing in a Cluster. For the web part (JSP and Servlets) basically you have to options: setup a Web Server (like Apache HTTP) to make use of the WebLogic Plug-in, that will then be connected to the WebLogic cluster. The other easier option is to simply use an LBR (load balance router hardware).
These are the "software" solutions you have for Load Balancing your web application in a clustered WebLogic:
WebLogic Server supports the following Web servers and associated
proxy plug-ins:
WebLogic Server with the HttpClusterServlet
Netscape Enterprise Server with the Netscape (proxy) plug-in
Apache with the Apache Server (proxy) plug-in
Microsoft Internet Information Server with the Microsoft-IIS (proxy) plug-in
You can read more about this options at the Configure Proxy Plug-ins documentation page for WebLogic 10.3.6.
I am trying to understand the working of HTTP , IIS and sql server.
I am having an IIS 7 server in my environment which is interacting with a sql database server.
The architecture is
Apache ----> IIS -----> SQL server
The Apache is a reverse proxy server which is sending the HTTP request to the IIS server and from there IIS server is interacting with the SQL database connecting by different application pools for different applications.
My query is if some request has been forwarded by the Apache server and it has reached the IIS ; after that, if the network between the Apache and IIS is having any packet drops ;
Will that have any affect to the performance of IIS and database server?
Will there be any long running queries in the worker process of the IIS? Because my concern is what will happen after the queries that has successfully executed in the Database server. But since the network between the IIS and Apache is broken how can they be forwarded further to the Apache and further to the end user.
Will these queries keep on holding the resources till they are forwarded from IIS to Apache? Because they have successfully completed their tasks but because of network issue they are not being forwarded further. Or are such request stacked up somewhere by the IIS to free up the resources for the upcoming requests??
Once a request has reached IIS it will go and do the required actions, and format the reply. It will try to send the reply to the requestor but if the link has gone, it will be unable to. It will then abandon the request. Resources it is holding for that request will be freed.
To get the data it had for you, Apache has to repeat the request.
I'm running a Rails app on Heroku's Cedar stack.
I need to access a remote Windows Server (over the internet, not in a LAN) to query a SQL Server database.
First, I used TinyTDS to access the DB but configuring it on Heroku is really painful.
Secondly, I had made a dynamic web page on the IIS remote server and I was making http get requests to retrieve data. But it's not secure.
I need a good and secure solution (ssh tunnel?).
Any help appreciated.
There's nothing wrong with using HTTP requests to interface between the two. If you want encryption, just use HTTPS. If it's just for internal use then you don't need to buy an SSL certificate, you can generate one yourself.
