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.

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

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

Legacy java app & Web Logic App Server

Hi,
We have a legacy java application that we like to provide an EJB layer
for.
The legacy application provides a servelet interface, event queues, our
own
JDBC Conn Pools, etc...
Can we integerate legacy java code into the Web Logic App Server? That
is,
we like to use the Weblogic's api's for servelets and JDBC conn pools.
We would also
like to use the clustering feature to provide failover. Also, our
application creates bunches of
threads. Do we need to rewrite this code to use Weblogics thread
creation techniques?
If this cannot be done,
another option would be to provide an EJB layer where the entity beans
would map to
elements in the legacy application using our own version of the
connector.
Then the app server would only encapsulate the EJB
layer. Could we still use your JDBC Conn Pools and other services in
the java legacy app?
Still the problem with this solution is that we can't use your
clustering scheme around our legacy app,
or can we?
Any help would be appreciated.

It can even be a standard production scenario if you want to run Oracle Portal 11g on a single box. The single sign-on part typically requires you to install an AS 10g SSO server which co-exists with other components such as WebLogic server.
Notice that there is a sharp division between everything which is inherit from the old OAS, the so-called instance components, typically started with OPMN and the new WLS stuff.

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...

P13N Server and App Server on separate systems - strange ports opened

Hi -
          We have a configuration using WebLogic Personalization Server 3.1.1 on one
          server and WebLogic Application Server 5.1 w/Service Pack 6 on another
          server. What we've seen with our firewall configuration is that it appears
          there are high-number random ports opened occasionally from the App Server
          to the P13N Server, which d not appear to be related to connection attempts
          (ex: port 42100). The only communication that we know should be happening
          between the two systems are T3-based JNDI lookups, LDAP lookup/update
          requests, and SQL queries. My questions, then, are as follows:
          1) In handling JNDI requests, are there any callbacks that can occur between
          the two servers in this configuration on a different port?
          2) When separating the P13N Server and App Server, are there any "private"
          ports opened between the two systems for management? As far as I know, the
          App Server should simply view the P13N Server as another client, but the
          firewall log would indicate that something is going on related to this.
          If anyone has a similar config and can provide some info related to
          potentially unseen port connections, please let me know. Thanks in advance!

How to set ORACLE_HOME for database and apps server in same server

Hi, I have problem here to set ORACLE_HOME in .bash_profile for database and apps server. please help me to set this Oracle Home.
Thanks
-jebatco

If you mean to have both simultaneosly set on the same OS session, of course that's not possible. But you can configure them on your profile, and choose them when needed. The following is an excerpt from my .bash_profile
export EDITOR=vi
umask 022
alias O='cd ${ORACLE_HOME}'
o10()
{       export ORACLE_SID=db102
        export ORACLE_BASE=/home/oracle/base
        export ORACLE_HOME=$ORACLE_BASE/OraHome10
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export TNS_ADMIN=$ORACLE_BASE/OraHome11/network/admin
        export PS1='[\u@\h_10 \W]\$ '
o11()
{       export ORACLE_SID=db11
        export ORACLE_BASE=/home/oracle/base
        export ORACLE_HOME=$ORACLE_BASE/OraHome11
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export PS1='[\u@\h_11 \W]\$ '
xe()
{       export ORACLE_SID=XE
        export ORACLE_BASE=/usr/lib/oracle/xe/app/oracle
        export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/server
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export TNS_ADMIN=/home/oracle/base/OraHome11/network/admin
        export PS1='[\u@\h_XE \W]\$ '
}If I want to set Oracle 10g environment I type "o10" at OS prompt, "o11" for 11g, and so on.

Cannot start Infra and App Server after reboot

I have installed iAS 10.1.2.0.2. on Solaris 2.9 -infra and appserver on same box. After installation I was able to configure Discoverer etc. The machine was rebooted recently and I cannot get the infrastructure and app server to start. opmnctl startall just hangs.

I think borkur is probably right.
We have our midtiers on different machines from the infra, but nonetheless, you could use the same sort of startup script.
What I do is go into a wget wait loop on the mid-tiers before trying to opmnctl start them:
#! /bin/bash
# script waitfordas
DAS_RESPONDING=`wget -q -O - http://infra.mycompany.com:7777/oiddas > /dev/null; echo $?`
echo Waiting for DAS to be up on infra.mycompany.com...
while [ "$DAS_RESPONDING" -eq 1 ]
do
sleep 10
echo Waiting for DAS to be up on infra.mycompany.com...
DAS_RESPONDING=`wget -q -O - http://infra.mycompany.com:7777/oiddas > /dev/null; echo $?`
done
echo DAS responded.
Then I call this in my startup script:
#! /bin/bash
# oracleas Start/Stop the Oracle Application Server
# chkconfig: 2345 99 10
# description: Starts and stops the Oracle Application Server
exec 2>/tmp/oracleas.err 1>/tmp/oracleas.log

return $RETVAL
restart() {

case "$1" in
start)
start &

restart
echo $"Usage: $0 {start|stop|restart}"
exit 1

Deploying servlet in iPlanet web or App server

Hello,
I have a simple struts implementation of servlet, which goes after LDAP
directory to fetch information. Under my local machine, I was just able
to copy the .war file to webapps folder under tomcat and it works.
How do I do it with either web server or app. server?
Any help is appreciated.

you can use the deploytool which installed in the {ias installed}/bin or a command line tool iasdeploy

WAS Monitoring DB and App server failures

Hi! I am using Websphere Application Server. I have deployed an application as a ear file (it does not have EJB.. just web components)
1) . I have my database server in another machine. I get database errors in between. How can I track network connections/DB connections from Websphere using logs/traces..
2) Also, is it possible to know from traces/logs that Websphere did not respond for a period of time.
Like I post a URL to Websphere and read from the URL to update a database in another machine. The class file which does that is in the WEB-INF/lib as a jar file . I saw from the Websphere stdout.log files that I get
java.io.FileNotFound Exception. "http://servername:9080/.....filename is not found.
Obviously, the file is always present as a jar file. So, it could be a Server:port error. But, how is that possible when it is the server:port of the app server. This did not occur all the time.
Soem days and like within minute many items failed. Later on during the same day, many other items weer processed. I am not able to fugure out what the problem is.. If WAS failed to respond can we get this kind of an error ? Does the machine need to be more powerful inroder to prevent this problem ?

So why posted in a JVM forum?
Still FileNotFound is not a server:port error. That is a Java error. If you give a wrong server:port you would be getting a 'Page Not Found' and this is a HTTP error message.
Cheers

Who is serving my page, web or app server?

I have my HTTP web server and Websphere installed on the same machine. When I deploy my ear file to my WebSphere, I noticed that my jsp files also go under the websphere directory. From this, I am guessing that when my jsp is called, the app server is the one serving the page.
Suppose I have separated my web/app servers. Does it mean that my app server will always be the one server pages, even basic HTML pages. If so then what is the point of having the web server?
Many thanks u all......

The idea behind having one of each is that your web server should serve up the "static" content - HTML, images and so on. The app server serves the dynamic content (JSPs, servlets, etc.), as well as any EJBs you're using. To each their own strengths.
Now, you do not have to have a separate web server - that's true. But if the majority of you site content is static and you have a lot of traffic, the separate web server will definitely increase your performance.

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.

And so on..so my requirement is I have to compare with internal table postal code to that file postal code, if it matches I have to do something, other wise I have to ignore, pls give me brief logic hw to compare.

Xaresource and app. server

Hi everyone,
i am trying to write a xa-resource. i went through JTA spec. at section
[3.3.1 Resource Enlistment], spec says
'for each resource in use by the application, the application server
invokes the -enlistResource- method and specifies the XAResource object
that identifies the resource in use. the enlistResource request result
in TM informing the resource manager to start associating the txn with
the work performed through the corresponding resource'.
Q1. how do i 'register' or let the app.server know about my XA Resource?
Q2. how does app. server knows which xa resources are involved in the
application?
thanks,
-talip

Hi,
Application servers and JTA implementations that don't do restart or crash recovery (like virtually all open-source products I know of) don't need you to do anything special for your XAResource.
It's a bit like driving a car without brakes: it works as long as there are no obstacles on the road.
On the other hand, a JTA implementation that works the way it should (and therefore does recovery) will typically have a custom mechanism to find out about your resource when it restarts or does recovery.
For more information, you can download our free developer release, or just download the JtaGuide from the same page:
