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.

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

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
-jebatcoIf 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

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!
Martinfor 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

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

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,
-talipHi,
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:
http://www.atomikos.com/download.html

Guy

Hello,
I'm currently tryig SJSC and I would like to use another instance f the App-Server and another version of the SDK (1.5_03). Is it possible to configure SJSC to do so or better just say while installation that SJSC should use the already installed versions? The OS is WinXP Prof.

ThomasHi Thomas,
Yes it is possible. you can have an other instance of appserver and in SJSC you can add that server instance as a remote server and deploy your applications to that server.

Logging in App Server 7 and App Server 8
Hi,
We have an application (servlets/MDBs/EJBs) running in the Sun Application Server 7 that we want to run on the Sun Application Server 8 (J2EE 1.4.2).
The application has logging facilities with various objects having their own java.util.logging.Logger...
java.util.logging.Logger m_logger = java.util.logging.Logger.getLogger( "ServletLogger" ) ;
m_logger.fine( "How do I get this in the App Server log file?" );
To enable the above logging in App Server 7, I would simply set the global App Server logging level to "FINE" using the admin console. How can I do the same with the App Server 8?
I've tried using the admin console to set the App Server logging levels to "FINE", but they seem to only effect the App Server itself and not the code it is running. I've also tried adding the following properties in the "Logging Levels" page of the admin console...
ServletLogger FINE
ServletLogger.level FINE
.level FINE
but they don't seem to make any difference? Any help will be most appreciated!
Cheers,
PaulGoto the admin console (port 4848 for default domain).
Click on Topmost Leftmost link -- "Application Server."
choose the "Logging" Tab.
Choose the "Log Levels" tab.
add a new property
com.company.app.applogger FINER and in your code, :-
Logger applogger = Logger.getLogger("com.company.app.applogger "); Now if only I knew how to keep a separate log file for this. -
Report display is different in report builder, local oc4j and app server
Hi guys,
we upgrade reports from sql report writer into report 10g. In the report 10g builder,
the report format looks fine. but if i use the url as below
http://applicationserver/reports/rwservlet?report=test.rdf&userid=username/password@service&desformat=pdf&destype=cache
so the format will be mess up whatever i use this url in my local oc4j or i deployed it into 10g application server. and the format is different in oc4j and application server. Why this issue happend?
Thanks in advance,
AppcatHello,
They are a Fix Pack higher than you which may explain why it's broken on their server.
Download the Fix Pack for R2 and see if you can duplicate the issue.

Why is printing report different from report builder and app server
I created a report and when ran from report builder it looks fine.
And when i moved the report to server and ran the report in the browser using this url
http://192.1.1.8:7778/reports/rwservlet?userid=esp/esp_dev1@wdev&report=FMMA_VOUCHER.rdf&destype=cache&desformat=pdf
and print it the report shrinks, the fonts become small and the margins change. I am having hard time how to figure out a way to correlate the formatting in the report builder and when i run on the server using pdf format.
Is there any way to set the server so that the pdf output matches with the report builder.
Thanks.
