ABAP+Java - MSCS Configuration on Web AS 640

Hi
We are in the process of migrating our CRM 4.0 running Web AS 620 (ABAP+J2EE) to CRM 4.0 Web AS 640 (ABAP +J2EE) on Windows 64 bit Microsoft cluster with Oracle 10g.
I have gone thru lot of installation guides for ABAP + J2EE (640) and do not find the steps for adding J2EE Server (640) to the Cluster.
As per the various guides, I believe the following procedure is right:
1) Install CI (ABAP)
2) Install Database Instance
3) MSCS Node A Configuration
4) MSCS Node B Configuration
5) Select Java Add-in for ABAP - Oracle (SAPINST)
    - SCS Installation
    - Java Database Schema Installation
    - Central Instance Finanlization
I am not sure about the Step 5, as I would have choosen Java System Finalization option under Java Add-in for ABAP (Oracle) in the Central System installation. If I choose Jaa System Finalization, the step 3 & 4 would be choosen after the Java System Finalisation.
Any thoughts on this would be highly appreciated.

Hi
Just to update on my progress.
I noticed there are different options in SAPINST for 32 bit & 64 bit. If you adding Java add-on to ABAP on 32 bit, the said SAP note needs to be implemented as there is no "High Availability option" under Java Add-on for ABAP in 32 bit SAPINST.
However, in 64 bit there is a option for High Availability install under Java add-on for ABAP. So, I believe the steps suggested in the notes are automated in 64 bit.
I checked both the sapinst and noted the following:
32 bit:
NW04 - Java Add-in for ABAP
            Oracle
                 - Central System
                 - Distributed System
64 bit:
NW04 - Java Add-in for ABAP
            Oracle
                 - Central System
                 - Distributed System
                 - High Availability System
                      - SCS installation
                      - Java Database Schema installation
                      - Central Instance Finalisation
                      - Dialog Instance Finalisation
We are configuring cluster on 64 bit, so i believe the steps outlined in the notes are automated under 64 bit.
Please comment.

Perform an export for both ABAP & JAVA in one shot with WAS 640 SAPinst ...

Hello,
I have to perform an OS/DB Migration of a SAP XI 3.0 (WAS640-SR1), an ABAP + JAVA addin configuration.
I would like to know if SAPinst for WAS640 (and SR1) could perform an export for both ABAP & JAVA in one shot as it seems possible in NW7.0 SAPinst version. None of the WAS 640 OS/DB migration guides gives these possibility.
And if not not, could U confirm that I have to perform 1st an export (with R3LOAD) of ABAB stack, then an export (with JLOAD) of the JAVA one ?
And apply the same way for installation with R3load and JLOAD downloaded files ?
Thks in advance
Bernard Accoce
SAP Basis Consultant - TeamWork in Toulouse (France)

Hi Bernard,
No, both exports cannot be executed in one single step. You have to execute the procedure twice, once for ABAP and once for Java, like you already mentioned yourself..
For the import applies the same.
Kind regards,
Mark

ABAP + JAVA MSCS installation on windows 2003.

Hello Everyone,
We are in process of installation of ABAP + JAVA in HIgh Availability on windows server 2003 , oracle database.
Our plan is to install ASCS, SCS, DB , CI on node A & DI on Node B.
In Installation guide its given that " Central instance installation " is to be done on local disk.
Can anyone explain why we need to do central instance installation on local disk?
Can we install central instance on shared disk instead of local disk ?
If yes, any other implicaiton later on.
Regards,
maitray.

Hi,
If you install CI on share disk than server performance will go down. since already you have ASCS & SCS on the same disk.
Thanks,
Vadivel

Web Dispatcher configuration (ABAP+Java vs. ABAP+Portal)

We are using an internal Web Dispatcher to allow the connections from different networks.
This Webdispatcher entry we add to WAS configuration within Portal system object
By defintion of ABAP+Java double stack we do not have any problems and the test
http://webpispatcher:port/sap/bc/ping is successful.
When we have a ABAP system + Portal (Java) we only can test the connection
http://webpispatcher:port/
When we execute the test
http://webpispatcher:port/sap/bc/ping we get an error, because the url goes to Java stack.
We also detected that on Web Dispatcher configuration for ABAP+Java we have ABAP and J2EE server groups and application servers.
For ABAP+Portal we have only J2EE groups on Web Dispatcher configuration.
Question:
Which SAP parameter (e.g. ms/server_port_0, icm/HTTP/j2ee_0) or Web Dispatcher parameter (ms/http_port) is responsible for generation of ABAP groups (e.g. PUBLIC) within Web Dispatcher?

Which SAP parameter (e.g. ms/server_port_0, icm/HTTP/j2ee_0) or Web Dispatcher parameter (ms/http_port) is responsible for generation of ABAP groups (e.g. PUBLIC) within Web Dispatcher?
In ABAP the logon group is handled by the ICF. In SICF you specify within the actual services(properties) which logon group that service should use for load balancing. As far as I remember though there is an exception if you are using an "end-to-end" ssl configuration where you can specify the destination logon group using wdisp/HTTPS/dest_logon_group parameter.
rdisp/mshost is the parameter on your web dispatcher that points to your message server to get a list of available logon groups.

Password resetting in web as abap+java

Hi,
I have installed portal 6.0 SR1 on Web AS ABAP+JAVA 640 SR1.
User I am creating in su01 through the ABAP stack.
Whenever I assign the initial password to a user created in this way or reset password of a user (through the ABAP stack), portal asks for new password and confirm the password.After this, it says "user authentication failed". 
The workaround for this is that with the initial password of the user, I have to login as the user in portal through ABAP stack.When it asks for new password and we confirm it, we have to user this 'new' password to login to the portal screen.
I would like to know whether there is a setting I have to make in the JAVA stack for this purpose, or this is some bug in abap+java stack.
Thanks and regards,
Kunal.

Hi Kunal,
u can reset password of user through Visual Administrator(from UserStore) or by WebAdministrator
for Visual Admin

Web Dispatcher and SSL on ABAP+Java

Hello,
Have installed SAP web dispatcher on WAS 6.40 ABAP+Java system. Communicating with Portal SP16 system.
The HTTP works fine. Have not been able to get SSL working with web dispatcher.
For troubleshooting activated ITS on this system and HTTPS works fine with ITS webgui.
Have followed the "how to" SSL for web dispatcher guide.
Also should mention that we have generated certificate requests and PSE's but our organization has not yet chosen a certificate authority to sign the cerficates. For other scenarios (log onto Portal, XI, etc) the only difference is the certifcate warning dialog, otherwise works fine. Would this cause a problem for Web Dispatcher?
Trying the SSL end to end scenario receive
WARNING: Could not start service 0 for protocol HTTPS on host "max-sap" on all adapters
Is there anything
unique for the ABAP+Java configuration?
Thanks,
Alan

I solved this problem by setting the following profile parameter on my webdispatcher profile.
wdisp/ssl_ignore_host_mismatch = true
Doesn't fix the underlying problem but got me going until I can figure it out.

Error while applying Java Patch 16 on WAS 640 ABAP+JAVA

Hello Digesh,
The firt thing please go to os level prompt for <SID>adm user and type echo $JAVA_HOME. What is the value that is reflected after issuing the above.
Also please check that your SAP-J2EE instance is running properly or not.
The JCE is used for Weak and strong encryption.
Also please check the instance.properties file. Does it contain proper parameter as per your SAP installation.

ABAP/Java Code to create ID configuration

Hi Experts ,
It is our project requirement that we need to create the mass ID Configs like ( Receiver determination / Interface determination) from the code (ABAP/JAVA)...
I have seen on the SAP docs that there is some web services available to do that .
Has anybody has this sort of exposure ...
Kind regards
Goutam

Hi,
For ID objects, I did not see any article yet.
But for IR objects or SLD objects, the answer is Yes.
Please check following blog:
XI - Reverse Engineering #1 Software Component

/people/felix.jeyareuben/blog/2007/03/22/xi-150-reverse-engineering-2-150-dependencies-in-swc-amp-adding-a-namespace
What you can do is to check the author of the blog to see if this is possible.

WEB AS 6.40 ABAP+JAVA

Hi all,

How shall i procced.
Can u tell me the Difference betwwen Portal and WEB AS 6.40 ABAP+JAVA ?
As I am new to this installation.

Hi,
please have a look to this overview of NetWeaver:
http://help.sap.com/saphelp_nw04/helpdata/en/30/c4461ff69d5a438f1286e344b545fa/frameset.htm

How to choose between Web AS JAVA / ABAP / ABAP+Java ??

Hello,
Does any one has an idea, what should be the criteria for choosing the web AS instance for NW Enterprise portal?
let us make it simple......
Can we compare (WEB AS JAVA/ABAP/ABAP+Java ADD-ON) & come up with advantages & disadvantages of the above three ?
Regards
Sunil Kulkarni

Hi Sunil,
I think there is no official statement except that both is possible, it depends on your needs.
But check out these docs:
http://service.sap.com/instguides -> Netweaver 04 -> Planning -> Technical Infrastructure Guide - SAP Enterprise Portal 6.0
and
http://service.sap.com/instguides -> Netweaver 04 -> Installation -> Installation Guide - SAP EP 6.0 (SR1) on WebAS 6.40
there you'll see that also the installation is more complex. Also patching the whole system will take more time as you have to patch also all the ABAP components of the application server.
If you can think of any need to have an ABAP stack on the same system, then make a good decision, because you can't install the ABAP stack afterwards as you can with the JAVA addin.
Regards,
Pascal

SAP Web AS ABAP + Java system

Hello All,
I am looking at the installation guide of SAP XI. I did not understand one thing from that guide. it says
"If you want to install the component SAP Exchange Infrastructure:Prepare the SAP Web AS ABAP + Java system for SAP Exchange Infrastructure"
I would appreciate if anyone of you can clarify what is SAP Web AS ABAP + Java system.
What I have been thinking all these days is we could have either Java(J2EE) or ABAP Web Application Server.
I don't understand what this ABAP + Java system is ?
Thanks in Advance

Hi Vanaja,
in the world of WAS 6.40 you can install it as three variant.
1. ABAP standalone (with it own SID) e.g. for R/3
2. Java stanalone (with it own SID) e.g. for EP 7.0
3. ABAP + Java as an Add in (Java and ABAP has the same SID)
For XI you have to install a so called double stack WAS 6.40 or SAP Web AS ABAP + Java System or ABAP + Java Add in. All this describe the same variant of the installation.
Normally you will have one database where J2EE-Scheme and
the ABAP-Schema is on the same database. I would really
suggest you to read the installation master SR1 there you
will get the understanding what is the difference.
regards,
Ly-Na Phu

ABAP Export in MSCS ABAP+Java Import

Hi,
I have an ABAP export from an HRP system (not a cluster one). I 've set up a new MSCS system for HRP, which is ABAP+Java and I know want to import the db to this new system. Should I consider anything before or after the import? Will the Java work correctly after the import? Or should I set up again the MSCS system with ABAP only, import the db from old HRP system and then install a Java Add-In in order to work correctly?
Any help will be greatly appreciated. And pointly appreciated also. Thx in advance.
