Re:Two application servers .

We would like to know the possibilty of having 2 application servers with Database.
Our Currnent setup - Databse is on one node and whole applications is on another node .
Now we got another Application server .
Requirement:- We would like to split the users of different units to access Applications; For example 'A' unit users can accessing Oracle Applications through only one URL & another 'B' unit users can only be access through another URL.
We have to make sure if 'A' unit users tries to login through 'B' unit URL it should not work.
Can you please suggest the recommended way to implement the same.
Regards .

Hi Hussein ,
thanks for the docs
i would like to also clarify whether the below requirement is possible
Requirement:- We would like to split the users of defferent units to access Applications; For examble 'A' unit users can be accessing through only one URL & another 'B' unit users can only be access through another URL to access the Oracle Applications.
""""""We have to make sure if 'A' unit users tries to login through 'B' unit URL it should not work """". is it possible ?

One iPlanet using two application servers?

Can anyone help, is it possible for one iplanet 6.0 instance using/connecting two application servers (i.e. one is JRun server, another is Webspere server) at the same time?
If so, how to do it?

I don't see why not. I have had the same webserver talking to both iplanet 6.5 and sunOne 7. As both the application servers will connect vias a plugin I would suggest you follow the instructions for both application servers and see what happens.

Issues with sharing a single OID with two Application servers (9.0.4)

We have two installations of 9.0.4 Application Servers and both share the same OID. We use Oracle Portal for deploying our jsp applications.
All users in the OID are sync'ed from Microsoft Active Directory.
Application Server 1 is for an application X
Application Server 2 is for an application Y
We create groups in the portal of Application Server 1 specifically for Application X. DEF_GROUP1 is default group for all applications in application X
DEF_GROUP1 has a default page - Page 1. DEF_GROUP 1 does not exist in Application server 2
We create groups in the portal of Application Server 2 specifically for Application Y. DEF_GROUP2 is default group for all applications in application Y
DEF_GROUP2 has a default page - Page 2
DEF_GROUP2 does not exist in application server 1
We have users who access both application X and applicaiton Y
For a user "JOHN" we assign DEF_GROUP1 in the user profile on the portal in Application Server 1
When we go to the user profile of "JOHN" on application server 2, we find that DEF_GROUP1 is a default group in the user profile of user "JOHN"
If we change it DEF_GROUP2, then the default group on the portal of application server 1 automatically changes to DEF_GROUP2.
Why is this so ? We would like to have a different default group for the same user in the two portal repositories. ?
Can any one provide some insight into this issue ?

Basically I started to develop this system inside Oracle AS and then when it came time to passing a request to a new page, it crapped out on me on the App. Server. So instead of trying to fix the problem there and then I continued to develop outside Portal and inside Jdeveloper. After a week or two once all my stuff worked perfectly I try and take it back into Portal but only the first JSP of all my Portlets would show up, because as soon as I would submit a form and the action directed me to a new page and Portal would be lost/confused. Obviously I shouldn't have done it that way but none the less...
So now I'm reading through the documentation you pointed me towards and it seems I have to qualify my parameters and then "attach" them to the url which the form will pass to the actioned page. I'm importing numerous classes (...urlUtils, etc) in order to qualify the parameters and then build this url without affecting any parameters currently present that my portlet does not own.
What I'm rambling towards here is all this separation of logic and presentation and the whole nine, implies different people can develop different parts of a 'system' mostly independant of one another...so in my situation I shouldn't in huge trouble yet, since underlying everything is a working system. My issue is with oracle and the App Server. If I take my code which works great outside of the App. Server and I fully qualify parameters and make sure my form actions are constructed using the UrlUtils in order to fully qualify them as well, and then I make sure page parameters are mapped to the proper portlet parameter values....should my system work on the App Server (assuming everything is done properly)....or am I still missing something.

Calling ABAP Web Service on the system with two application servers

Hello all,
I try to figure out, how to setup a web service in the TC WSCONFIG in the multi application server environment.
Basically the requirement is that when WSClient calls my WS, it should not care about accessibility of one or another application server. In other words the WS's URI should contain the IP/domain name of "SAP Web Dispatcher" or other component, which handles the loadbalancing.
I think it could be done in ICM within WSCONFIG transaction, but I'm completely lost inside the setup. Also I was not able to find proper helpsap page with the description.
Is there a WEBLOG or any other document how to setup this ?
Thank you for your help in advance.
Regards
Tom

Hello,
You do not have anything to do in SAP transactions.
The HTTP load balancing is the SAP Web dispatcher job.
Just install and configure the web dispatcher. Follow HELP.SAP.COM, it is well explained.
We use this config to load balance 200 000 web servce calls/day on 5 abap application servers.

Olivier

Two application servers

Dear all
I installed Oracle AS in two servers:
*1. Windows Server 2008 R2*
*2. Oracle 10g Application Server R2 (10.1.2.0.2)*
*3. Two servers: oracleap1 & oracleap2*
Now both servers are working fine.
what is the best way to make these servers working simultaneously (same time), so all clients can use each server (by this i'll get best performance) ???
I asked network administrator on my company. He guided me to make an alias for both server (as oracleap). so now I can use oracleap instead of both servers. As he says, by this way the client will use the available server at a time.
Any other Idea??
Kind Regards

Replicate All Service Application into two Application Servers

Hi All,
I want to replicate all the service applications into another application server in order to configure HA.
we are having two servers having single farm.
Please Help..!!

Install SharePoint on server 2
Join Server 2 to the farm
Activate the services on server 2.
http://technet.microsoft.com/en-us/library/ee704549(v=office.14).aspx
Most service applications can be run on multiple servers (and are designed to). The exception is the User Profile Application Synchronisation Service, which can only run on one server in a farm at a time.

How to install two Application Servers with shared Portal DB?

I currently am supporting a 9ias 1.0.2.2.2 server that has an existing Portal database on another 9i RDMBS server. Everything runs well in this environment, but now management wants to add another 9ias server (different IP address and DNS Name), and point it to the existing Portal database. I've installed the Application Server without installing Portal, but that's as far as I've gotten.
Now I'm at a loss as to how to proceed with the Portal Install. Can I install the software and point it to a new database, then modify the DAD and tnsnames files afterwards? Or is it more complicated than that?
Thx in advance,
Julie

WebDynpro Notification Service with multiple Application Servers

Hello Experts,
I am currently working on a project where I have to integrate a BSP Application into a new Web Dynpro ABAP Application. On the BSP Page it is possible to edit some details (for example for a customer).
When the user start to work on the BSP Page, the Web Dynpro Page should prohibit the navigation (i.e. disable all links). After Saving the BSP page, the navigation lock is released and the Web Dynpro reloads some data, which were changed from the BSP Page.
I have a NetWeaver 7.02 so I decided to use Shared Objects and the new Web Dynpro Notification Service to realize the given requirements. On the development system everything worked fine. The Notification Service was called and it took about 2 Seconds until the Web Dynpro Application updated.
But we got serious problems on the testmachine, which uses a Web Dispatcher and two application servers. After some research we managed that the application is running, and works.
But the Notification Service takes now up to 1 Minute until it fires the registered actions. And I good frequently an ASSERTION_FAILED from the method CL_WDR_NOTIFICATION=>ATTACH_FOR_READ in the ST22 as long as the application is running.
Can anybody help me how to solve this issue. It is a real blocker for the project.
If there is another way to establish eventing between Web Dynpro and BSP I would also go for another solution. But I don't think there are many other possibilities (SAP Portal and NWBC are no options - Maybe the new Web Dynpro PageBuilder?).
Best Regards
Daniel

Hello Guys,
we decided to do a workaround for the moment. We use a refresh button on the Web Dynpro screen. That is not very nice, but sufficient for the moment.
Anyway: I am still interessted in the BSP-Web Dynpro Interaction Issue. So if somebody has any ideas, please let me know.
@PageBuilder: Currently the page builder does not work on the system, because of an 403 - Error when I try to call the Application-Configurator (the SICF service is active). But I will try this also as soon as this problem is solved.
Best regards
Daniel

Mount Points in Application Servers

Hi ,
I am planning to install ECC ISU , EP and BI in production environment.
ECC & BI are On AIX and DB2
EP is on Linux and DB2
We will have two application servers for all systems ( ECC, BI and EP).
Can anyone please let me know , what are the sap related mount points (or, file systems) that should be present in the application servers of these systems ?
Thanks and Regards,
Moulinath Ray

Thanks a lot Sunny.
What I understand from your comment ,
1. /sapmnt and /usr/sap/trans are to be shared between CI and all application servers.
2. /usr/sap/<D01> or <D02> has to be created as local mount points in all application servers.
3. The structure will remain same for all systems (i.e. ECC, BI & EP)
Can you please confirm ?
Regards,

How many application servers do I need??

Does anyone know at what point i would need to consider using two application servers instead of just the one??
Is it based on number of users?? Is it based on hardware spec??
or both
Thanks
G.

Hello
I don't know about your configuration of hardware but my practice (bigger company) is good to have etc.one sever as infrastrocture (OID..SSO, portal repository,...) and other for forms and report server as middletier... And around 100 f10 forms users per server/middletier...For more, just add another middletier server and use network load balancer...If you have many print jobs it's good to have for reports other server as middletier which is not in NLB.

Apache / JRUN setting up trust between two app servers

Hi,
I have two applications running on Apache web server and JRUN app server.
How can i setup a trust domain between the two jrun app servers so that the user doesnt have to enter authentication credentials in both the servers when forwarded from app server 1 to app server 2?
Thanks in advance

I researched that we can do a "fake" authentication by using cookies. Has anyone does this before? Can somebody guide me on this?

Configure CRS2008 to using AD and Kerberos with Java application servers.

Hi All,
I have configure CRS2008 to using AD and Kerberos with Java application servers. Domain Controller is installed on W2K3 Server. In addition, CRS2008 is installed on another W2k3 Server.
I have create service account in domain controller: CMSACC
I have create two user account: CRuser1 and CRuser2
I have create domain group: CRSGroup

I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.

My problem is failed to logon CMC and infoview and got error message at below:
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserNameatDNS_DomainName, and then try again.
Actually, I am sucessful to logon Business View manager with CRuser1. However, I fail to logon CMC and infoview and got the above error. Have you any suggestion to solve this problem?
Ken.

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

Multiple Application Servers - Same class instance

Hi,
Due to increasing load we have to add multiple Web Servers and Application Servers (custom built) for our Web Application.
As currently we are using 'synchronized' for adding and releasing connection in ConnectionPool and also using static in several other classes - we have to make these few classes single instance across the application servers.
We are using iPlanet 6.0 for Win 2000. Is there any way we can direct specific classes for a single instance. Please provide me with all sorts of alternatives.
Thanks a lot,
Suman Biswas

Hi,
Yes, we have different JVMs. Different JVM means different processes,now there can be two cases,these process running on same machines
or on different machines.If it is in different machines then undoubtly you require to go for the Distributed Technology(RMI for java).
As we have couple of classes which are using
'synchronized' - cann't we use centralized classes for
these couple of classes to maintain integrity?Yes you can do it,now this centralized class should be available in common place from where your all applications can get results,and for avoiding the data corruption your require to go for synchronized(if some global variables) block,since the same instance will be serving all the requests.
When you say RMI - my question is how the commercial products handle these kind of issues while they are in multiple servers?I have created some application using RMI but not the same one which you had specified.I had used it for different purpose.

Session cleanup issue with multiple Application servers

Hi ,
I am facing a strange problem with multiple application servers. The java Webdynro session does not get cleaned up completely when user closes the browser ( without using logoff ). On re-login it gets handle of old session and then fails for consecutive view on other webdynpro iviews with an invalid session error. It again starts working with a refresh event.
Any ideas/suggestion if you have seen something similar before ?
Thanks and regards,
Amit.

Hi Amit
It seems that issues is not server related, but caused by your client browser. I know, for example, that IE8.0 keeps user session even if two separate browser instances opened on the same client machine. IE 7.0 and lower behave differently - they are separate user sessions per browser instance.

How to access two entity managers from two different servers?

Hello
My test programm is trying to access two glassfish application servers (gf 2.1). The code base of these servers is the same, the persistence layers are just accessing different databases -> one ist the staging/test system, the other the live server.
After setting the connection and obtaining the em via the class persistence i can not fetch the em from the other system.
          properties.setProperty("org.omg.CORBA.ORBInitialHost", "host1");
          properties.setProperty("org.omg.CORBA.ORBInitialPort", "port1");
                InitialContext ctx = new InitialContext(properties);
          entityManagerFactory1 = Persistence.createEntityManagerFactory("pu/refdata");
          entityManager1 = entityManagerFactory.createEntityManager();After that Persistence seems to have been bound to host1 forever, so i can not fetch a reference to the em of host2. There is another createEntityManagerFactory method accepting a map but i dont find any reference for the properties, maybe that would help - dont know.
Regardless of what i do, any further call to Persistence.createEntityManagerFactory returns the handle of entityManagerFactory1.
Regards

I want to use the EntityManagers bound to the DataSources provided by different app servers.
Below you find an example persistence.xml with three entries. 1 & 2 have the same jta data source, 3 is different.
My point is that Persistence binds the new factory in a wrong way if the jta data source String has already been resolved.
If a progamm sets connection properties for app server 1 and fetches an entityManagerFactory for pu/refdata_Live, then sets connection properties for app server 2 with pu/refdata_Test they get different factory instances bound to the same server, in this case app server 1.
If i know set the connection properties for app server 3 with pu/refdata3 Persistence sees that the jta data source "dbc/ref3" has not yet been resolved and tries to connect to the app server 3. Which it should have done for app server 2 too.
<persistence-unit name="pu/refdata_Live" transaction-type="JTA">
     <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref</jta-data-source>
    <properties>
      <property name="toplink.ddl-generation" value="none"/>
    </properties>
</persistence-unit>
    <persistence-unit name="pu/refdata_Test" transaction-type="JTA">
    <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref</jta-data-source>
    <properties>
      <property name="toplink.ddl-generation" value="none"/>
    </properties>
</persistence-unit>
    <persistence-unit name="pu/refdata3" transaction-type="JTA">
    <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <jta-data-source>jdbc/ref3</jta-data-source>
    <properties>
