Web and appln server

hi once again
Yet another question : What is the difference between a web server and application server? Functionally how do the 2 differ? Can one assume the functions of both? Please Help

Web servers handle static content like HTML pages.
There is a hierarchy of app servers.
Servlet/JSP engines have Web servers built into them, so they can also handle static content. But they also can act as a container for servlets and JSPs, so they can also handle dynamic content. You can use JDBC to access a database and do 3-tier architectures with servlet/JSP engines.
J2EE app servers have Web server and servlet/JSP engine built into them, soi they can also handle static and dynamic content. But they can also act as a container for EJBs. They support the entire J2EE suite: servlets, JSPs, EJBs, transactions, messaging, naming, etc.
EAI servers can tie together multiple J2EE app servers.

Help me Decide on OpenBSD or Solaris as my web and file server please

Hi
5 questions
i have been using OpenBSD as my Web and file server for a while now
and FreeBSD as my Desktop
i decided on OpenBSD as my Server because of its Security
1) But now i hear Solaris is the most Secure OS pn the Planet? is this true
And which is real Unix?
i seem to always have trouble with things such as PHP on OpenBSD
Most of my pages run as *.html but i also have a forum which uses PHP 4
But all my PHP pages come up blank..
i am always encountering errors using PHP
2) If i Switch to Solaris will it b even harder to use or
is it precompiled with PHP 4 and higher when i install Apache
3) Also what about cgi and the ability to use *.htaccess files should i use them
4) Also i i still would like to generate SSH keys ssh-keygen
is that possible?Forcing the user to login using only a key and
not a password on SSH
5) Does Solaris have any Linux compatibility as well?as FreeBSD has
Concider me a newbie even though i use to post on this forum once before
i am always experimenting trying new things out

Either will work just fine. Since you're asking in the Sun forums, you should receive more Solaris replies of course! :-)
The weak point in your setup (as far as security goes) would be the use of PHP either way...

Deployment of Flex app to web and app server

Hi
I'm working on putting a Flex front-end on an existing J2EE
app which gets deployed as an ear file. The architecture consists
of web server, app server and database server. Is the following
approach to deployment possible / recommended?
My Flex app will be deployed to the web server. The J2EE ear
file will be deployed to the app server (Weblogic). BlazeDS will be
bundled within the ear file as a war file. Remote Objects will be
configured in my BlazeDS configuration files to enable me to access
the code in my J2EE app. In the compiler options of my Flex app,
I'll be setting the server root folder and server root URL to point
to the BlazeDS war file on my app server.
At present I'm at the stage where I can run my Flex app
directly from Flex builder on my development PC and it's able to
connect tto the J2EE app, which is running on the app server
(Weblogic) also on my development PC. I can't find documentation
explaining how to extend this to work on a multi-tier architecture.
Thanks
David

Web and Application Server

Hi
My web and application roles for SharePoint are on a single server in which the hardware failed. I have SQL and the databases on another server. Is it possible to rebuild the server and connect it to these databases to restore the data?
Thanks

As suggested by Scot, Rebuilding a server with the same Farm configuration database is not good to go because you may get some encountered error when associating the existing configuration databases.
Suggesting you to create a new SharePoint farm with same build version and then attach the content databases to this newly created farm.
Thanks

**Diiferences web and app server**

hi techs
i am a newbie to application server concept.
first i want to know why we need application server.
and what is the difference between web server and application server.

You need to install "Webconnector" plugin to connect to Sun One webserver and App server..
The webconnector pluging comes with Appserver binary.

Diff Patch Level on External web and Source Server

Hi ,
Version - 11.5.10.2
We recently setup our external web server in DMZ on Linux while our source system
is running on Solaris.
We followed 238276.1 doc to migration the middle tier to linux. We were asked to check
both systems should have same Patch level.
I have doubts here
o Since we have only one DB Tier, and we copied APPL_TOP from Source solaris and
convert the files to linux. we installed IAS and 8.0.6 home from Universal installer
Is it possible to have diff patch level on both instances. as we have only DbTier
and the only way [ I know ] to check whether we have patch applied or not is
query to database or using OAM as it would show the same patch.
o if there is possibility to have diff. patch level then how can we detect this and what is the way to apply patches on one server [ Adadmin ? ]
o Can you please point me to any DOC which can give clarity how diff. type of patches
we can have in Apps.
Regards,
Jagjeet Singh

How To Apply a Patch in a Multi-Server Environment
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=136342.1
Patches must always be applied in their entirety. If you apply a patch to update
your filesystem, you must also apply the corresponding database and generation
portions of the patch if they are included. When updating the filesystem in a
multi-server environment, you should apply the patch on all servers.
You can see what patches have been applied to which nodes in OAM on the Applied Patches page. Oracle will not advise you to have patch differences, otherwise supportability comes into question due to partial patch application.

How do I fix the web and wiki server - error reading settings?

Hello,
      I upgraded to OS X Mountain Lion and installed the OS X Server. The Wiki pane has the error message "Error Reading Settings". The Websites pane looks fine, but when I click on "View Server Website", I get the webpage that simply says "Server Error". (I am wondering if these are interrelated, which is why I put them in the same discussion.) I will note that the admin tools must have changed since trying to follow the discussions for previous versions of the Server leads to paths that are not present. Any suggestions on what to try would be most appreciated. Many thanks!

Hello. Unfortunately, serveradmin is indeed one of those paths/tools that are no longer present in the new version of OS X Server. Either that, or it is renamed to something new that I am not aware of. However, doing a ps -A | grep -i postgres, I get the below. I am not sure if this really means postgres is running or not. Looking in system.log file, I am noticing a weird error (attached). Any thoughts on this would be most appreciated. Many thanks!

BACK button difference between Weblogic and J2EE server

          Hi Everyone,
          I have a J2EE application implemented mainly with JSP and EJB, which can run on
          both J2EE and Weblogic Servers seperately. When running on either of them, the
          server acts as both a web and application server.
          It is my understanding that it first goes to the cache in the browser when you
          try to revisit the previous page (JSP files) by clicking the BACK button in the
          browser. If the page is there, it just displays that page from the cache. If not,
          it will go to the server to retrive (execute) that page.
          When I run my application over J2EE server and try to visit the previous page
          by using the BACK button in the browser, it does this way correctly. But when
          I run my
          application over Weblogic server, it always goes to the server and execute the
          JSP file again in the server, rather than simply retriving that page from the
          cache. If your JSP file is simply doing data retriving, that is fine. But if it
          is doing data inserting, it will insert your data again. This is not good.
          I know that the Weblogic server is mainly an application server. But I am not
          sure when it acts as a web server,
          why it works differently from J2EE which also can acts as both an pplication and
          a web server. Does anyone have any ideas or suggestions about this?
          Thanks a lot.
          -John


I believe that the correct behaviour is to rerun the .jsp page unless the
          user specifically sets the header to allow the browser to cache it. That
          being said... You should never make a web application that can be broken by
          the user hitting "reload" or the browser automatically retrying. An
          application like this is very fragile and will probably break in practice.
          I suggest that you either make all your pages idempotent or you keep track
          through a hidden form field a transaction id and only allow the execution of
          any particular transaction once. As far as WebLogic not being a good web
          server, I would say that with 6.1 you get most of the management advantages
          of using a separate web server and also most of the static file performance
          you will find with apache or IIS.

Replace FE and APP server in SharePoint 2013 farm

Hello,
We have to replace the front-end web and app server from a SharePoint 2013 farm. The farm only has 1 FE, 1 APP and 1 SQL server. As the FE and APP were wrongly patched and have unsupported software installed there's no way of getting all servers
at same version level and to succesfully run the Product Configuration Wizard. The database server is ok but we have to replace the 2 other servers.
Is there any documented procedure to perform this migration/reinstall?
Thanks!
Martin

for first approach.
1- go to central admin and add all roles you need for the server that will stay
2- log into the server you will remove then run configuration wizard and choose disconnect from farm
you will have now one server, you can clean it up and keep it or later remove it when u have the new one
3- to add new server

Web host, mail server and FTP.

Dear all:
I have some questions and will try to make my post a short one (although the questions aren't exactly simple). I have the need to set up my own web server, e-mail server and FTP server. It is my understanding (and I remember setting another computer I had 2 or 3 years ago this way) that OS X can be used for this without the need to have OS X server installed. I don't need (at least not for the for the immediate future) to have a server for my own local network. Basically all I need is a single computer where (1) I can host multiple web sites, (2) I can host my own e-mail that will correspond in number to the number of web sites (domain names) being hosted and (3) I can set-up as a FTP server so that my clients can log on and download files.
I have used VirtualHostX for virtual hosting as well as PureFTD Manager with good results in the past. I've also found both to be easy to use, with a good and intuitive GUI which is essential for someone with as little knowledge as I have of networking. My question now as to do with e-mail and how to set-up Mac OS X to work as an e-mail server.
Are there any applications you would suggest that would be simple to use, have a simple and intuitive user interface and also provide mailing list services along with e-mail services that you would recommend ? I've looked at a few but most of the ones I have found seem to require command line input and this is something I am not comfortable with. I need an application with a simple interface and allows things to be set-up in a straight forward manner (and preferably free instead of paid).
What would be your recommendations for this project ? Any recommendations, advice and suggestions you can offer will be very appreciated.
Thank you in advance,
Joseph

Perhaps you should give people more time to answer.
1. You do not need a DNS on your server, ask the ISP to set up the MX record as they set up the A record.
2. Not really enough information in your setup to say either way, but as it takes seconds to do and you have everything else needed - set it up anyway.
3. Domain name: mydomain.com, Host name depends what you call it. If you don't have a name why not mail.mydomain.com and make you mx record point to that name. Perhaps that is what your A record is already.

To configure SSIS packages out of these SQL Server Standard, Web and Workgroup editions which is preferred?

Hi All,
To configure SSIS packages out of these SQL Server Standard, Web and Workgroup editions which is preferred?
Grateful to your time and support. Regards, Shiva

Hi Shiva,
SSIS designer and runtime, basic transforms, and data profiling tools are only supported by Standard and higher editions. Besides, some advanced SSIS adapters such as High performance Oracle/Teradata destination and Dimension processing destination adapter
are only supported in Enterprise edition. So, if you need to develop/modify SSIS packages on this server, Standard or even Enterprise editor is recommended.

My Wikis and Ical on the WEB give a Server starting up.. message

Wikis (and Ical on the WEB) give a Server starting up... message with the turning wheel. They were working perfect, and yesterday started the problem. I have not changed any of the server settings neither permissions. From Mozilla Firefox on windows throes an Mac OS X server message
500: An internal error occurred trying to process your request. Sorry. Safari gives a Server starting up..
I checked permissions and look ok, root and admin group have read & write access. to
/Volumes/DATA HD/ServiceData/Web/Documents/Collaboration folder and up in the path.
Does anybody know how to solve this?
I tried updating to OS X 10.6.5 but the problem continues.

I am having a similar issue as you marktech, with colaboration folder on a different drive.
My temporary solution is to stop and start web services on the server, and the message goes away and users can log in. Problem comes back on a server restart.
Swamped here so have not been able to apply troubleshooting techniques.
What I have checked is verifying permissions on collaboration folder. Seems like I had to re-apply permissions after any significant update.
My final resolution will be to migrate from the ssd hard drive (the extra speed is not any significant impact for us) to a 1TB hard drive and migrate data back over to a single drive in original directory locations. appologies have not had ample time to research the issues....

Installing Iplanet web server and directory server behind a firewall

When installing iplanet web server and directory server behind a firewall - should the interal ip address be used or the external ip address?

Hello,
When you are installing iplanet web server behind a firewall,you should use the internal ip address in the firewall.
1. The external ip address connection to the Internet. The type of IP address used?dynamic (commonly used for standard
modems) or static (commonly used for cable modems) is dictated by the ISP to which you connect and the type of service it provides.
2. The internal ip adress connection. This connection must be a static IP assignment, and it must be assigned by you.
obviously it depends on the type of firewall setup you have.
Thanks

Web Start and Game Server

i have a client-server game and i would like to put it on my site
i've managed to put both the client and the server
the problem is when i run the server, i give it a port and it opens and says waiting for a connection, but when a client joins it doesn't detect it
of course, this problem doesn't exist if i run the server jar file from my computer and then run the clients (webstart or console), it's only loading server through web start that it doesn't work
so, if i run the server through webstart, then run a client through command prompt, what happens is it connects, server doesn't display a connection detected message and then client just drops out, seems like the sockets don't connect properly???
thanx

i generated a key and signed the jar file, but it still gives the same error
seems like i need a java.policy file in order to allow connection on the ports >1024???
i made a policy file, but in order to use it, i have to give it as a parameter to the jar file
so, java -jar myjar.jar -Djava.security.policy=java.policy
now, the problem is how to make the jnlp file run my class file with the -Djava.security.policy=java.policy parameter???
the policy file contains:
grant {
permission java.net.SocketPermission "*:1024-65535",
"connect,accept";
permission java.net.SocketPermission "*:80", "connect";
};

Difference between web server and application server

Hi Everybody
Could anybody expain difference between web server and application server?
Sharad

Hi there
The difference I know is the application servers provides the containers for the applications to run which is not provided by the web servers.
For example the containers can be an EJB container or JSP container etc
