Oracle Application Server cluster on Linux - Help Pls

Hi,
I am having two seperate Linux machines on which I am trying to install Oracle Application Server. I need to cluster both the IAS installations. What are the different ways I could do it? I have read a couple of documentation which says that I need a hardware cluster to do it. Is it possible to create an IAS cluster without a hardware cluster.
Would creating a farm using file repository and then adding two instances of two seperate Linux machines be enough for clustering? While trying to do so, I am not able to add the second linux machine's file repository in the web farm. I checked if the ports are open. All the ports are open. Still I am not able to add the second instance as part of the farm.
Pls help.
Thanks,
Vidya

Hello Vidya,
it depends on what you want to use with Oracle AS.
If you only installed the Java Edition (J2EE/WebCache installation type) then you don't need a HW cluster. Yes you only have to install a managed cluster based on a file based repository.
How did you add the nodes to the farm?
Install on both nodes the Java Edition. Be aware of that
you checked during the installation the file based repository.
For node 1 execute the following commandos on Linux:
1.) dcmctl getRepositoryId
2.) dcmctl joinFarm âr <repositoryId> where <repositoryId> is the ID which you get in step 1
For node 2 execute the following:
3.) dcmctl joinFarm âr <repositoryId> where <repositoryId> is the ID which you get in step 1
After that you should see in Oracle AS Control (web based Enterprise Manager) both nodes in the farm.
Then create a cluster and join the AS instances to the cluster. Do this via the web based console.
Regards
Kersten

How to start Oracle Application Server 10g on Linux

Hi,
I have installed the Oracle Appliacion server and Infrastructure server on Linux. Both I have installed under with Diff. folder
Can some one please tell me how to start / stop Appliacion server and Infrastructure server on Linux
We are going to use the these with Oracle EBS 11.5.10.2 .
Oracle EBS 11.5.10.2 installed in the same Linux server under diff. folder
Can some one please guide me.
Thanks,

You can do as rizla said or go another route.
We setup profiles to use for all of the oracle homes. Then in the scripts we call the profiles. Easier to migrate and manage in my opinion if you have multiple oracle homes. You can then use profiles when ssh'd into the boxes, too. Both ways will work.
Example:
Script which you can chkconfig.
#!/bin/sh
# oracle_collabInfra
# This shell script takes care of starting and stopping Oracle Collab Infra instance.
#chkconfig: 345 96 14
# Source function library.

Oracle Application Server 10g (Application Running)

Dear All Sir/Madam
It is my humble request that please tell me how to run Application on Application Server 10g.
I developed my Application in Oracle developer suit 10g (build internet appliacation), and I am using *10g database*.
Now please tell me the complete procedure who to configure oracle application server 10g on linux.

Hello Ghulam,
Notice that you can deploy different kind of applications within the Application Server framework, e.g. JEE applications, PL/SQL applications, Forms Applications etc. Based on what you initially mentioned, it seems that your have developed a Forms application. The above document reference refers to Application Server 10.1.3, which was a JEE / SOA release. You are probably better off with the [url http://download.oracle.com/docs/cd/B14099_18/web.1012/b14032/toc.htm]Forms Deployment Guide.
One note : Application Server 10.1.2.x is soon to be desupported. Consider to move to version [url http://www.oracle.com/technetwork/developer-tools/forms/downloads/index.html]11.1.2 !
Thanks,
EJ

Hello,
Did you copy the 2 JAR files in your /forms/java directory ?
Did you add them to your /forms/server/formsweb.cfg file (archive_jini tag) ?
As always when a Java Bean is in the game, display the Java Console at runtime to see if any error are raised.

Oracle Application Server On Linux Problem

Our client's application server has been live for 6 months now and currently there is an issue.
This server is a Dell 6850 running Red Hat Linux ES 3.4 (Taroon Update 5) and kernel 2.4.21-32 with 2 CPUs and 8Gb of ram. Our J2EE web application runs in Oracle Application Server and currently 5 OC4Js are up and running.
The issue we are facing is the server has frequently gone to a hang state. When this happened, we won't be able to telnet into the server but there are ping responses. So the only thing to do then would be to reboot the server.
Now I have setup nmon for linux to run 24 hours in the server taking snap shots of the server's performance every 10 minutes. From the nmon output, I could see free memory is always around 20Mb - 50 Mb and sometimes would shoot up to 1Gb and then in 3 hours back down to 20Mb - 50Mb. Is this a normal pattern for a linux server?
From the Oracle console under memory usage, I saw that around 1.5Gb is being used by the Application Server, 36Mb free and 6.5Gb used by other processes. Now, I am curious as what this other processes are and why are they using 6.5Gb.
I am not sure if this is caused by a faulty hardware, OS/kernel bug, or our web application.
What I have done:
i) monitor /var/log/messages but no suspicious error being logged not even before or during the server hang.
ii) monitor Oracle Application Sever log files but no suspicious errors logged.
iii) monitor nmon output daily
iv) searched for similar cases using Google and Oracle's Metalink but found nothing.
Thanks.

As a followup ---
We believe that we have found the culprit finally based on two lucky catches during lockups. Last seven days we have been testing various combinations of centennial agent and enterprise agent running and have successfully tracked issue down to these two products not wanting to run together.
We have 32 machines with centennial running and no emctl and there has been no issues for last 18 months. The machines we have had problem with are the ones that use enterprise agent also. We disabled centennial agent on 8 machines and left it running on 6 machines that had emctl agent. We were still experiencing failures on the 6 machines but no failures on 8 machines.
We turned off centennial software on the remaining 6 and have had no lockups since. Based on this we are concluding that "emctl agent" and "centennial agent" dont play well together and so plan to discontinue using both of these together on any machines.
Did not reseach exactly why these two were causing a system panic but since these are production and vital we will live with workaround.

Specify Oracle Application Server EM Port in \ETC\SERVICES File - Help

Hi,
Can anyone tell me what to soecify in the /ETC/SERVICES file for Oracle Application Server Enterprise Manager Console 9.0.4 , so that the port is not used by any other process.
I have had situation where a rogue process was using port 1810 and was preventing the console from loading up.
Can anyone help??
I have to do this on a production system.
Thanks

Did you get an answer to this question?
I'm looking for the same information thanks to a rougue piece of software that removed my entry in /etc/services for port 1810 during it's install. I don't know what the service name should be. Of course - there was no backup copy of this file made prior to the install. It's a development box, so it doesn't get backed up often.
I can get the infra page to load fine, but the midtier page will not load.
I'm curious to know if you ever found anything on this.
Thanks,
Deb

Oracle Application Server Environment Variables for Linux

Hello All,
I have installed Oracle As (infratructure & middlie tire) on same box.
10g Release 2 (10.1.2)
Now I need to do post installation steps as below.
ORACLE_HOME
1) How to set to the full path of the installation's Oracle home?
2) Do I need to also set ORACLE_HOME for middle tier?
ORACLE_SID
(Infrastructure installations only)
3) How to set the OracleAS Metadata Repository SID supplied during installation?
cheers,

Hello,
I have installed Oracle AS Infrastructure (10.1.2) and BI & Forms on our Linux box.
Now I am doing some post installtion steps .
Per Oracle® Application Server Quick Administration Guide 10g Release 2 (10.1.2) B14126-02
\http://download-west.oracle.com/docs/cd/B14099_10/core.1012/b14126/toc.htm
**Set to the full path of the installation's Oracle home
ORACLE_HOME=/opt/oracle/infra; export ORACLE_HOME
** Set to the OracleAS Metadata Repository SID you supplied during installation.
ORACLE_SID=orcl; export ORACLE_SID
Is it the correct way to setup ORACLE_HOME & ORACLE_SID?
Actually I have setup as above on Last thursday. (09-15-05)
But when I have checked today (09-19-05) as
echo $ORACLE_HOME
I got nothing.same with SID, now I need to set again.

Oracle application server 10g help

Hi,
I need to work on a project that pulls data from the oracle database and should be able to generate reports based on user entered criteria and they want me to use the oracle application server 10g.
(I also need to do manipulations on the data pulled out.)
How do i start and what are the things that i need to install..
If somebody could guide me in a few words, i can pick it up from there...
Thanks

Hi,
Thanks a lot for replying..
This is a simple overview of my project..
Basically i need to convert a client server application which was initially in Access (and coded in VBA) and oracle to oracle based web application.
The application that was built in access has various flaws and hence we decided to rewrite them with lot of new features..
what i would need is several web pages(probably intranet based...) where i pull data from the oracle db, and then do manipulations on them and then based on certain criteria come up with a report based on users needs...
I hope this info is enough to guide me
Thanks.
