Regarding Application Servers

Hi,
i need to know the basic dfference between the application Servers,
JBOSS and Weblogic
Which one is feasible for Enterprise applications and how ?

How about giving a try to Sun's AppServer? It has all features enterprise might need and it is absolutely free!

SAP R/3 Enterprise : Background job run on application servers

Hello All,
For our SAP system (SAP_BASIS 620, SAP_ABA 620,SAP_APPL 470), there are 5 application servers and one central instance.
We have a Background job that connects to external non sap system for data delivery via RFC of Type "G" i.e.HTTP Connection to Ext. Server with port 443 . RFC works fine.
In transaction STRUST, SSL certificates are also installed to enable the https connectivity from R3 system.
Our current issue is that background jon runs on one of the application server correctly and is able to transfer that data to external system. However if same job runs on other 4 application server, it fails to connect to external server and throws error:
RFC Destination XXXX not defined
407 Unknown error
Failed to store the XML content
Error in the XML document: 1301540.xml
407 Unknown error
This is very starnge for us .RFC is working correctly every time but background job works on one AS and not on other AS.
Where and What can be the difference in application servers.
Please help to send in ur replies. Thanks

Hi,
Is there a firewall between the non SAP system and the SAP system ? It could be that firewall rules have only been set for one only of the SAP application servers ?
Did you check the HTTP connections from each application server ?
Did you check that the ICM is running on each SAP application server ?

Regarding Application server file path browsing

Hi All,
I have a issue regarding Application Server File Path browsing.
Actually in my selection-screen i will declare a parameter as Application Server File Path now when i press F4 in that field it should be able to browse through Application Server Path's.
Just like F4_FILENAME in the case of Presentation Server File Path Browsing.
Can anybody solve my issue.
Thanks in advance.

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,
Moulinath

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

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
After I had run the setspn in domain controller,I got the message at below:

Default AD Domain: BD.com
Add AD Group(Domain\Group): secWinAD:CN=CRSGroup,OU=TEST,D=BD,DC=com
Service principal name:BOBJCentralMS/CMSACCatBD.com
I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.
bscLogin.conf:
com.businessobjects.security.jgss.initiate {
com.sun.security.auth.module.Krb5LoginModule required;
krb5.ini:

I have tested the Kerberos,using kinit CMSACCatBD.com password, and got error message at below:

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

Tim

Check SITSPMON at multiple application servers at once

Dear Sirs,
we are in a setting with close to 10 application servers. To the memory consumption and current status on my system, I need to check SITSMON on every application server.
Is there an easy way to get a STISPMON like (e.g watch memory) on all the application servers in one go?
best regards,
Jørgen

Dear Jørgen,
at the moment we do not have an easy way to monitor more than one application server within SITSPMON. I am the developer of SITSPMON and happy to read your question. I do agree in your wish to have a feature like this.
How to implement? I would suggest to provide an additional check box in the dialog panes for
*the memory staistics,
*the HTML templates cache directory, and
*the Mutex lock statistics.
This checkbox allows to switch between 'system' and 'application server mode' checking it will result in an enhaced table, containing an additional column for the appl server...
Do you agree? Better ideas? If this fits to your requirement, I will implement this. And ideas are welcome always.
BTW: Did you already check the CCMS? There a technical experts monitor for the internal ITS. This might be helpful four you.
best regards
Tobias

Portal pointing to Backend (Multiple Application Servers)

Hello Experts,
Landscape details : NW04s SP17 Portal for Travel Expense pointing to ECC 6.0 backend (running with 3 application servers). We don't have web dispather installed on the ECC 6.0 system, and client has no plan to install that also.
We have created portal system with Load Balancing template and using logon group (all 3 backend application servers are part of this logon group). In portal system, we have configured -
1. Connectors - using logon group.
2. User Management with LogonTicket.
3. ITS - pointing to specific application server - Can't we use logon group for ITS traffic going to backend
4. WAS - pointing to specific application server - Can't we use logon group for WAS traffic going to backend
In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
As per my understanding ITS is used for transactional Iviews.
When will Connector and WAS connections will be used?
Thanks
Davinder

Hello Experts,
1. Connectors - using logon group.
2. User Management with LogonTicket.
3. ITS - pointing to specific application server - Can't we use logon group for ITS traffic going to backend
4. WAS - pointing to specific application server - Can't we use logon group for WAS traffic going to backend
In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
Regarding points 3 & 4:-
http://help.sap.com/saphelp_nw04/helpdata/en/42/5cfd3b0e59774ee10000000a114084/frameset.htm
You can only use the SAP Message Server for HTTP load distribution, if the browser is the direct client of the message server. If another component lies between the client (browser) and the message server, (for example, the portal), you cannot use the message server to distribute the load.
So this is a requirement to use the webdispatcher if your backend is called from the Portal. Otherwise all requests will go to the CI.
(Q) In ESS/MSS (Travel Expense) scenario, what kind of calls will be made to backend and will these be through Connector, or ITS, or WAS?
(A) It depneds on how you have configured the services. Usually its via HTTP, HTTPS or a SOAP adapter to a FM.
Hope this helps

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.

Kernel Upgrade reflecting in application servers

Hello All,
I have question regarding kernel upgrade .
while performing kernel upgrade ,we uncar the files and replace the exe file in central instance (/sapmnt/<sid>/) .
After restarting the server , it is automatically getting reflected in appl.servers too.
Can any one tell me the work around beyond it .On what basis this is exactly getting updated by default in appl. servers too ?
Best Regards
Rakesh

If you look in the start profile of the application servers you will find the sapcpe program that runs at startup. This program is responsible for going out and looking to see if there is a newer kernel available at the CI. If it does see a newer version it will copy the correct files out to the application server.

Do all the weblogic application servers need to share storage in order to implement high availability?

I would like to understand if a shared storage is required for all application servers that will run weblogic + oracle identity manager. I've been using the following oracle guides : http://docs.oracle.com/cd/E40329_01/doc.1112/e28391/iam.htm#BABEJGID and http://www.oracle.com/technetwork/database/availability/maa-deployment-blueprint-1735105.pdf and from my interpretation both talk about configuring all the application servers with access to a shared storage. From an architecture standpoint, does this mean all the application servers need access to an external hard disk? if shared storage is required what are the steps to implement it?
Thanks,
user12107187

You can do it and it will work. But Fusion Middleware products have EDG to provide guidelines to help you to implement high availability.
Having a shared storage will help you to recover from storage failure, otherwise this might be a point of failure.
Enterprise Deployment Overview
"An Oracle Fusion Middleware enterprise deployment:
Considers various business service level agreements (SLA) to make high-availability best practices as widely applicable as possible
Leverages database grid servers and storage grid with low-cost storage to provide highly resilient, lower cost infrastructure
Uses results from extensive performance impact studies for different configurations to ensure that the high-availability architecture is optimally configured to perform and scale to business needs
Enables control over the length of time to recover from an outage and the amount of acceptable data loss from a natural disaster
Evolves with each Oracle version and is completely independent of hardware and operating system "
