Forward to different web-app on same server

I can forward a request from a servlet to another web-app on same server, but the authenticated principal is not propagated from original servlet to forwarded servlet. I'm using the requestDispatcher.forward(req,resp) method. It seems that if you forward to a web-app within same EAR or server than the user's identifty should be propagated.

With tomcat you can use single sign on .

Can you run multiple APEX listeners for different instances on the same server

Please confirm that we can run multiple APEX listeners for different instances on the same server? Is it an xml setup configuration or do we need to do more??

How to track session IDs for multiple apps in same server instance?

All:
We have 2 web applications (for example: app1,app2) running in one app
server instance (weblogic 5.1). Both of those applications use the same
cookie name (defined in weblogic.properties ) to keep the HttpSessionID.
The tricky thing is that if a client logs in to app1 and then logs in to
app2 with the same web browser, (for example, IE). The app1's
HttpSessionID kept in the cookie will be overwritten by app2's
HttpSessionID because they use the same cookie name.
My question is this:
Is there a way to specify a cookie name for each application running in
an application server instance?
The only way we know of to work around the problem is that we have to
host the app1 and app2 in 2 different app server instances so we can
config app1 and app2 to use different cookie names for the
HttpSessionID. We are curious if there is a better way to do that.
BTW, We must use Cookie because of the requirement of cluster and load
balancer.
Thanks,
Ben

Hi Ben,
Which version of Weblogic are you using??
In 5.1 sp8 the Cookie names of the Web Apps are different by default.

Why can't you add your own cookie?
In 6.0 you can have different cookie names for different
apps.

Problem with multiple Toplink/JPA apps in same server

Anyone have experence of running serveral Toplink/ EJB-3 Web apps in the same server (OC4J, alas)?
We seem to get a problem with the second app failing to initialise toplink, with an entity not found message. Each app runs OK on it's own.

Yes, they access the same datasource and most of the tables overlap.
We're thinking it might help to have common entity classes and put them in a shared library, but I don't know if this is relevant (setting up shared libraries complicates testing and tends to snowball, I reckon we need about 15 jars all told).
I''ve had some funnies on OC4J before which I think may be to do with it's use of ClassLoaders, for example I initially put persistence.xml in the libary jar with the data model, but for some reason I get the entity not found error that way. It only seems to work if it's in the classes folder.
For the moment we're getting arround the problem with multiple OC4J instances in the server.

Is it possible to have 2 instances with the same name but different edition in the same server?

Hi everybody!
I have in a little trouble ....
*** Scenario.
Oracle Enterprise Edition 11gr2 over Oracle Solaris 11
3 instances: PROD, QA, DEV
1 ASM instance
Listener ports: 1520, 1530 & 1540
           Those are production system
*** The problem:
Customer can't pay Oracle EE, they want to change to Oracle Std One
Limitations:
I cant have a similar system to test.
*** My idea:
Install Oracle Std One, in the same path:
/u01/app/oracle/product/11.2.0/db          <-- EE
/u01/app/oracle/product/11.2.0/db_one   <-- Std Ed One
ASM:
/u01/app/11.2.0/grid          <-- EE                    +ASM
/u01/app/11.2.0/grid_one   <-- Std Ed One        +ASM1
Create databases:
Asign similar disks to +ASM1
Create DGs on +ASM1
Create databases: PROD, QA, DEV for Std Ed one
- is it posible that they have same instance name?
- if not, i suppose create as: PROD1, QA1, DEV1
Configure Listener port : 1521, 1531 & 1541
Migration technique:
Create Tablespaces, schemas
Lock users in EE
down listener: 1520, 1530 & 1540
Import data of final users in a window maintanance
configure and up listener: 1521, 1531 & 1541
Customer should test access and apps in new
Please tell me if my Idea is reallistic, all comments are going to be very apreciated.

sol.beach
I suppose end customer use a port per database in order to separate in a logical way the access to the databases,
i mean PROD, QA & DEV has the same users.
Hemant K Chitale
1. I've seen physical servers with 3 ASM instances: +ASM1, +ASM2, +ASM3
   on Solaris & Oracle 10g, I suppose is posible on 11g
2. The sever has occupied 2 sockets (2 physical CPU), so I can use Oracle Standard Ed One.
JohnWatson2
Thanks for your comments.
WadhahDaouehi
1. - You cannot run two ASM instance simultaneously on one Server, but you can run many Oracle database simultaneously
      on the same server which they use the ASM as storage type.
As a mentioned to Hemant K Chitale, I've seen a system with several instances running
About
     "you can run many Oracle database simultaneously on the same server which they use the ASM as storage type."
I'm not sure if i can use the same ASM which is part of a current Enterprise Ed over the new installation with Oracle Std Ed One.
2. - Why you want the same instance name?
If it is about the service name, which has by default the same instance name, just you can create a different instance name
and create the service name with the name that you wish.
SQL> alter system set service_names='instance_name';
Is a similar name, not the same
PROD, QA & DEV
PROD1, QA1 & DEV1
I consider add "1" at the end to refer "Oracle Standar Ed One"
But I agree with you, i can customize throught service_name.

Deploying a copy of existing database with a different name on the same server

I am a developer(an inexperienced one) trying to understand what is the best way to deploy a brand new database with
the exact same schema as an existing DB on the same server, but with a different name. I want to preserve the data in all reference tables which I can do by having the relevant post-deployment scripts run after the deployment.
What I can't understand is how the project should be set up to deploy database Customer_2 if database Customer_1 exists on
this server - the Visual Studio project contains DB Customer and I need to find a way to be able to deploy Customer_N (but without creating N identical DB's in the project). I checked a ton of articles and blogs, and feel dumb asking this question but haven't
been able to understand it yet. Any help would be appreciated.

Hello,
Maybe the TargetDatabase and the DeployToDatabase properties can help you.
http://www.asp.net/web-forms/tutorials/deployment/web-deployment-in-the-enterprise/deploying-database-projects
You can deploy multiples databases from one project if you want, as explained on the following

Multiple oracle database instances with different characterset on the same server

Hello,
Is it possible to have 2 database instances running with different charactersets,one with AL32UTF8 and the other with WE8MSWIN1252.?
Are there any setup requirements to be performed prior to setting up the database instances?
The 3rd party utility that we want to use does not support AL32UTF8 and insists on using a database with character set WE8MSWIN1252.
Kindly help.
Thanks,
Ram.

Hello Zhe,
I guess I posted my question in a wrong forum. I tried my best to find a suitable forum and thought this was the best and closest I found. Apparently not. Can you please let me know the right forum for my question?
The below is the breif of what we are currently facing:
We are in the process of finalizing plans to install Automic for our Retail applications to schedule jobs. In the process came to know that Automic does not support AL32UTF8.
Right now we have RMS and UC4 (now called Automic) run on the database server as UC4 supports AL32UTF8 and schema for UC4 is inside the RMS database.
Going forward it is recommended to have a separate database instance on the same server as that of RMS database and with a different characterset which is WE8MSWIN1252.
Please let me know what forum to post in, I will repost the question.
Thanks,
Ram.

Multiple web apps sharing same cache in a single JVM ?

Is it possible to share cache across multiple web apps running in the same app server (multiple web apps, single JVM) ?
Thanks for any info.

Hi Bob,
Cluster membership is scoped to the ClassLoader, so if your application server provides a ClassLoader-per-application, this will work fine.
This is supported for both Coherence (NamedCaches) and Coherence*Web (HTTP sessions).

Different logon pages for same server.

hi Expert,
I have created two different logon pages with different URL's for the same server, now i can use both the pages to logon in to the system.
what i need to do now is :-
URL "A" users set ="A"
URL "B" users set ="B"
If we have the above two different URL and respective users for those URLs.
Now if i am User from the User set "A" and try to Login by using URL "B".
I am able to login, but i want to restrict.
ie.
users from set ="A" login only by the link URL "A"
users from set ="B" login only by the link URL "B"
Points would be given to helpful answers.
Regards,
Sanjyoti.

Hi Sanjyoti,
I am not sure if this would work, but if time permits then do try this.
User A -- URL A
User B -- URL B
Now make User A a part of Group A, and set conditions in code that Group A can logon only through URL A and User B can logon through URL B.
Then in code check the association user - group and group - url and accordingly allow / disallow the user to go ahead.
This is just a thought.....do tell me if this works.....or if it doesnt then do post the solution you use....

Falied "Configure OLAP cubes for Project Web App" in Project Server 2013

Hi
I'm trying to use the PS2013's capability for generate SSAS Cubes; but after I execute
the steps described on “Configure OLAP cubes for Project Web App (http://technet.microsoft.com/en-us/library/jj943761.asp)” the only thing
achieved is that the state being "Processing…" and the log:

When I check the jobs, the one who is associated with the cube creation is on "Succeeded" state but the OLAP database is never created. There is no evidence I think on the Sharepoint log.

I want to install to different version on the same server

Hi all,
I want to install two different version of oracle on same server.
and Both should work parallely without disturbing to each other.
I know it is possible
But while installing what preliminary precautions I willl have to take so that it won't disturbed other running database.
waiting urgently for reply
Pramod

I would think as long as you set up separate staging areas for the two different versions that there should be no conflict. As always though - make sure you have good backups - maybe two.

Same Application Variables name in different websites on the same server.

Hi,
I have two websites in the same server that use both their own Application.cfm file.
In each Application.cfm file is defined the application variable Application.DB
In website1 the Application.DB = DB1
In website2 the Application.DB = DB2
Since I'm studying Application.CFC solution, and I did read that application variables with same name have as scope the entire server ... I'm a bit worried. This happen also with Application.CFM ?

Since I'm studying Application.CFC solution, and I did read that application variables with same name have as scope the entire server ... I'm a bit worried. This happen also with Application.CFM ?
That's not quite how it works. Each application has its own name, and application.foo on one application (name) is a different variable from application.foo within a different application (name).
Reading these sections of the docs might help:

Multiple apps (instances) same server?

Hi all,
          Are there any known issues with having multiple apps share the same weblogic.jar file?
          I have a Tomcat server that has the same app installed twice; Productive and Test.
          When both are started, they seem to be unable to read from their queues. The following exception was thrown:
          [Security:090398]Invalid Subject: principals=[jndi, Deployers, Monitors, Operators]
          When we only started one instance (either Productive or Test) the single instance worked perfectly.
          Now, we have installed both instances on seperate servers and have started both and they also appear to be working perfectly - however, it would be more ideal for us if we could get them working in harmony on the same server.
          Is it not possible to share the weblogic.jar file?
          Cheers,

barnes,
          Thanks your response.
          The application (both) do create their own threads (daemons), but I can not see how they could be intertwined.
          I've ran tests to make sure they do reference their own settings (memory) and all seems to be ok.
          What I can't test is the internal workings of Tomcat, maybe somehow something goes awry internally there!?
          When I get a chance, I'll run some more tests... If I get something working, I'll post the results here (if I get the time).
          Cheers

Can I have 2 different EP instances in same server.

Hi Friends..
I have Enterise portal installed on server. It uses UME engine of SCM4.0 server.
Client weants to install EP for different SCM5.1 system along with the old one. I am new to EP and moreoevr have no idea if tha is feasible. They say they will publish 2 links on internet.... 1 with having link to SCM4.0 and other with SCM5.1.
Can you please provide me the guideline or some material abt same.? Is it possible and what are the risk factors. coz I have no ep development for R&D and we can't risk stopping our current EP working fine with SCM4.0
regards.
Ranjan

Hi Ranjan,
Considering your server sizing the performance will take a hit. But Still you can install 2 instance of EP in this server. All you need to take care is
1. Your SID of the instances should be different. Eg.,EPD & EPP
2. Your http port should be different. Eg., 50000 & 50200
For productive use it is recommended to have atleast 2GB for one instance exclusively. In your case you have only 4GB out of which your OS & DB will consume more than a GB. So consider increasing the RAM size.
HDD free space 10 GB should be enough.

Log4j doesn't create backup files in web-app, the same code in pure java ap

Hi all,
in my application I have a class DummyLogger, which is a superclass to all others. It provides them a log4j Logger.
In the constructor it sets up the important attributes:
log = Logger.getLogger(name+" (" + app + ") ");
log.setLevel(Level.toLevel(level));
PatternLayout defaultLayout = new PatternLayout("%p %c,line %L,%d{dd.MM.yyyy/HH:mm:ss},%m%n");
RollingFileAppender rollingFileAppender = new RollingFileAppender();
rollingFileAppender.setName(name);
rollingFileAppender.setFile(path+app+".log", true, false, 0);
rollingFileAppender.setMaxFileSize("10MB");
rollingFileAppender.setMaxBackupIndex(5);
rollingFileAppender.setLayout(defaultLayout);
log.removeAllAppenders();
log.addAppender(rollingFileAppender);
log.setAdditivity(false);Formerly I had the application as a pure java app and everything worked fine. Now I've made it a web application (I run it on WebsphereAS 5.0) and it has stopped creating the backup files. However the code remained the same.
Any ideas what has happend?
Thanks a lot,
Ondra

I also have the same problem. Did you find a fix?
