10g Application Server Clustering

Hello All,
We have recently decided to move our standalone server to Oracle 10g 2 node RAC for which the preparations on the test environment have been initiated, so far oracle 10g DB have been setup on the 2 nodes with failover settings. Now my primary concern is to check on options for application servers failover settings, i would like to know if application server needs to be clustered. If so, is there a separate software for this clustering ? or do i have to install application server 10g software on each node separately and just specify DB servers details in TNS for the application server and failover is totally dependent on the DB RAC configuration. All i want to determine is how application can be safely failed over to the next available node with no downtime or loss of transactions/data. Here is a brief summary of setup:
Node 1 - Win 2003 R2 Enterprise Edition, Oracle 10g RAC database (10.2.0.3.0)
Node 2 - Win 2003 R2 Enterprise Edition, Oracle 10g RAC database (10.2.0.3.0)
Could you also answer to following :
a) How should i replicate/keep in sync my application data (a folder containing regularly changed forms/reports) on windows to node 2
Thank you
Ali

Hello All,
My target is to achieve failover for oracle forms based application. Now this is what i have currently in my setup :
1) 2 nodes with win2003 r2 (32 - bit)
2) Oracle RAC DB 10.2.0.5.0
3) Oracle Application Server IAS 10.1.2.3.0 on each node
I have included TNS entries for TAF under Oracle Infrastructure home of IAS and also under Oracle MiddleTier home of IAS.
After completing all the setup when i test failover for the clients like TOAD, SQL for the RAC DB it is absolutely fine. Unfortunately when i test my forms application for failover by switching off the DB to which forms client is connected it simply errors out "UNHANDLED EXCEPTION" and the session closes abruptly. Are there any specific settings i have to make in order to ensure forms client failsover to the next running node rather than getting disconnected with loss of transactions.\
I also look forward to get an input with respect to failing over Application Server 10g to the next node.
Thank you.

10g Application Server 10.0.3 Topology

Hi, all!
Could anyone tell me if there's a place where I can find information regarding the new JMX feature for 10g Application Server? It would also be useful to know about topology (clustering,...) and scalability.
Thanks in advance!

please help me.

Hi
You have to deploy Servlet as a WAR File. I hope you already have web.xml file which u can get automatically in eclsipse during creation of servelet. I am not sure what ide u r using here. If u have created servlet in eclipse then I would suggest create a project dynamic webproject if u have not where IDE create all required files autmatiicaly and even you can deploy application from there itself.
If you wanted to deploy manually then follow below steps (if u have war file)
I am assuming you already created a Weblogic Domain and have admin username/password. Start your domain. Login into weblogic console like http://host:port/console and use admin username/password. Then from Deployments section, deploy the above WAR file. In Weblogic you can deploy JAR (EJBs, java files), WAR (web jsp, html, webservices, servlets) or EAR (JAR + WAR). In your case its just a WAR file.
Thanks

hi buddies,
I want to know that whether

pls do send ur replies if known to you.

Hi ,
As far as I know AS 10.1.2.0.2 is Not certified with JDK 1.5.
Please see below some links where you can double-check this

Urgent: problem running reports in Oracle 10g application server

Hi all,
our problem is that we deployed a jsp report as Ear file in Oracle 10g application server in infrastructure node.deployment says successfull.when we try to run that report it says 401 unauthorised.while sending request we are passing the database username,password &sid is this correct or any configuration setting to be done to make it run.
one morething normal jsp works fine.when we run reports jsp it gives the above mentioned 401 error.

hello,
when you deploy reports JSPs they still require the reports specific componentes (e.g. TLD file, classes, ...) etc be available. i doubt that's the case in your ear file.

Server B:
then, i now hv to set up a 10G application server and 10G discoverer on a new server. The user request that they want to login to discoverer using the username and password as mentioned above. They reject to logon to database using 'connect directly', 'open connection' or 'private connection'.
what can i do in order to synchronize the username from Server A to Server B so that they can logon using the username and password they created in e-business suites.

Installation of Oracle 10g Application Server in custom port or 1522

I want to install Oracle 10g Application Server in Port 1522 or some other port as in port 1521 Oracle 10g database server is already installed.
But every time I try to install Oracle 10g Application Server it give the warning about 1521 port and then start installing on same 1521 port automatically.
What should I do if I want to install in some other port ?
Please help
Thanx

As a method, to install an OAS on a custom port,
1) make a file called staticports.ini and define your components/ports there.
2) on the Specify Port Configuration Options screen, select Manual and specify this file.
Follow this link for details for 10g.
http://download.oracle.com/docs/cd/B14099_19/win.1012/install.1012/install/reqs.htm#CHDJACIG
However, there are ways to use the same port for OAS and DB depending upon the version of your listener. Check the version of your DB Listener, and if it is 10.1.0.2 or higher then you are just good to go with automatic port assignments.

Auditing in oracle 10g database and oracle 10g application server

Dear friends,
We have oracle 10g application server and oracle 10g database server in place.My criteria is to audit users connected using oracle application user credentials to the database.
Can you please tell me how can i do it.
Thanks & regards,

Its the database connection you want to track. The session audit will show where it came from.
Auditing is turned using this command:
alter system set audit_trail = DB scope=spfile;
Note: The use of spfile will require a DB bounce before audit starts
To audit Sessions:
audit create session;
Query by Audit Type:
SELECT A.USERNAME,
OS_USERNAME,
A.TIMESTAMP,
A.RETURNCODE,
TERMINAL,
USERHOST
FROM DBA_AUDIT_SESSION A
WHERE USERHOST = <replace with iAS servername> ;
By User
SELECT USERNAME,OBJ_NAME,ACTION_NAME , TIMESTAMP
FROM DBA_AUDIT_TRAIL WHERE USERNAME = 'SCOTT';
Check for users sharing database accounts
select count(distinct(terminal)),username
from dba_audit_session
having count(distinct(terminal))>1
group by username;
Attempts to access the database at unusual hours
SELECT username, terminal, action_name, returncode,
TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS'),
TO_CHAR (logoff_time, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') <
TO_DATE ('08:00:00', 'HH24:MI:SS')
OR TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') >
TO_DATE ('19:30:00', 'HH24:MI:SS');
Attempts to access the database with non-existent users
SELECT username, terminal, TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE returncode <> 0
AND NOT EXISTS (SELECT 'x'
FROM dba_users
WHERE dba_users.username = dba_audit_session.username);
Other audits you might consider:
audit grant any object privilege;
audit alter user;
audit create user;
audit drop user;
audit drop tablespace;
audit grant any role;
audit grant any privilege;
audit alter system;
audit alter session;
audit delete on AUD$ by access;
audit insert on AUD$ by access;
audit update on AUD$ by access;
audit delete table;
audit create tablespace;
audit alter database;
audit create role;
audit create table;
audit alter any procedure;
audit create view;
audit drop any procedure;
audit drop profile;
audit alter profile;
audit alter any table;
audit create public database link;

Does 10g application server 10.1.2.0.2 work for 9i database?

I have installed 9i database on UNIX. then I am trying to install 10 application server 10.1.2.0.2. But somehow it force me to install a complete 10g database, which is undesireable for me. So I just wonder whether 10g application server can work for 9i database? If it works, how to install 10g app server with 9i database?

Hi,
The 10g database installed by the 10.1.2.0.2 application server is used by it as a metadata repository for configuration and also as an LDAP server for the Oracle Internet Directory.
What components of the application server do you need? If all you want is Forms and Reports services, there is a standalone version that does not install the 10g infrastructure database.

Unable to get 10g application server control page

Need Urget help
hi
Operating system windows 2003 with sp1
Application server 10g-- v 10.1.2.0.2
I have installed both 10g application server infrastructure and middle tire sucessfully on the machine with all the components sucessfully installed without any component failure or error.
i can access welcome page on
http://localhost:7777 or
http://hostname.domainname:7777
sucessfully but when i try to login to application server control from welcome page
it directs me to http://hostname.domainname:18100 but doesnot display any page
no error just blank page with status done at status bar.
-- but i can access server control page using
http://hostname.domainname:18100/emd/console
login sucessfully after entering username and paswword
but why i can not access it just by specifiying
http://hostname.domainname:18100 also when i try to start or stop any components no response after pressing stop/start/restart button available.
-- same problem with
http://localhost:7778/forms/frmservlet no button shows any response or any error on configuration or on any other components web page.
i checked all almost every thing
all services or running sucessfully
plz i need ur help.

I saw this on another windows machine as well. I believe that the port should be 1800 and not 18100. Look into the emd.properties and check if they are configured correctly.

Benifits of 10g(Application Server)

Hi,
I want to know the benifits of oracle 10g(Application Server) as compare to Developer 6i.Actually we are using an application built on forms6i & reports6i with Oracle 9i database.We want to convert that application on Oracle 10g(Application Server).For this we will give a presentation to our managment shows the benifits of new tech. over previous tech. which we are using.
Thank's in advance

There can be various factors to be considered. I'll list some of them, from my experience :
- End user point of view : if current architecture is Client/Server, and depending on geographic Clients distribution, there could be a quite sensitive performance enhancement. This is not a general tip, it depends on some factors, but we often noticed such an enhancement passing from Client/Server to Web architecture.
- Technical point of view :
-- if current architecture is C/S, then you won't need Forms runtime anymore on each Client, just a browser. Moreover, if you don't use a centralized file server, now you have to update each Client for software management.
-- if current architecture is Web, then 10g is much easier to install and configure, especially if using standalone version Forms and Reports services, and more flexible and powerful.
-- your version is already desupported, and assuming we are speaking of production environment, this could be a problem.
