Error in creation of JCO with Load balancing server

Hi,
We are using a ABAP user base for our WEBAS server 6.40 (with ABAP+JAVA). i have created a Public group in concerned ECC 5.0 system. I have already configured SLD, and then i maintain data supplier bridge in SLD and run RZ70 in ECC 5.0 system to load system information.. i can see details in SLD ..
now i am trying to create JCO connections .. here i am unable to create JCO with load balancing option.. i get
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=<servername> GROUP=PUBLIC R3NAME=SID MSSERV=sapms<SID> PCS=1 ERROR service 'sapms<SID>' unknown TIME Fri Jun 16 12:41:20 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapms<SID>' not found SYSTEM CALL getservbyname_r COUNTER 1
i am able to create single server JCO, but it fails in load balancing.. is there anything i have missed out in settings...
Thanks and regards,

Thanks, Bogdan Rokosa
I have the same problem,and solved it following the steps provided by Bogdan Rokosa :
you must insert an entry for your R3 system
(like: sapms<SID> 3600/tcp)
in services file
(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.
I test the Jco successful without restart J2EE Engine.

Trouble in a SAP system with load balancing

Hello masters:
I had a trouble with workitems that came from a SAP system with load balancing. They doesn't receive the workitem ID in the UWL.
I created another system in the portal as a "dedicated application server", and made the necessary configuration in order to replace the first one, and then my workitems worked fine.
However, I would like to know what appened with the first system created as "system with load balancing". Why this system didn´t pass the workitem ID to the application (web dynpro abap) that execute the workitems?
Thank you.

I hope there was some missing configuration in the first case which was not replicating the workitem from SAP Inbox to UWL.
Thanks

System with load balancing server

Hi All,
We are having SAP NW 7.0 Portal and back end we have R3 implemented in a cluster environment. The system object in EP have used "System with Load balancing" template; using the LOGON group and the other related parameters.
But we have some problem with the ITS and WAS parameters; since we are using some Transaction iViews.
Let me explain.. for the R3 cluster we have 2 systems PROD1.domain.ext and PROD2.domain.ext. Now in the system object in portal, how to specify the parameters for ITS and WAS parameters? Since the host name in these we need to specify a single server which defeats the basic purpose of having clustered environment.
Can any one please help in resolving this issue.
Thanks,
Sravanthi

Hi Sravanthi,
Please check the below for finding ITS and WAS parameters from backend :
For ITS - Go to SE37 >> Utilities >> Setting >> Click on ICON Right Top Corner in popup window >> Select Internet Transaction Server >> you will find the Standard Path and HTTP URL.
For WAS - Go to SE37 >> Run FM - RSBB_URL_PREFIX_GET >> Execute it >> you will find PRefix and PAth paramter for WAS.
Please refer to this may help step-by-step : How-to create a portal system for using it in Visual Composer
Hope it helps

HTTPS with load balancing

Hi guys,
We have a portal system with instance 08, so we typically connect to the portal using port 50800 for HTTP, and 50801 for HTTPS.
We have just created a second server node for this portal (in the config tool).
When we connect to 50800, does this automatically load balance the user to the better server? From some reading on these forums, it seemed to indicate that load balancing will only occur if I connect using port 8109. (where 09 is the instance number for the SCS of our portal)
When connecting to port 8109, we are redirected to port 50800, as I'd expect.
Question 1 - do we need to use 8109 for load balancing, or can we still use 50800?
Question 2 - If we need to use 8109, which is a HTTP port, how can we achieve load balancing with HTTPS. Is there a different port we need to use to have HTTPS with load balancing?
Question 3 - Is the creation of a second server node the best way to accomodate additional users and load on the portal system, or is there a better way to do things?
Thanks,
Michael.

Better late than never.
The load balancing you describe through the message server has its limitation. It redirects you to one of the dialog server hosts which means that any bookmarks will always point directly to a dialog server which may be down at that moment.
Access directly to a dialog server on port 50800 will sort of load balanc on the java server instances that are on that server but not on other servers.
The general recommendation is to setup an external loadbalancer and SAP Web dispatcher is a good match if the load is not very high. SAP webdispatcher will then bind up the cluster address and act as a proxy towards the dialog servers of the portal. The user will therefore only see one address. This will also work for HTTPS.

Moving SMTP server to Azure with Load balancer

How to

Hi TechM,
Base on my experience, Windows Azure Platform does not provide out-of-the-box mail server (neither SMTP nor POP3). You could use SendGrid to sent mail. About this issue, I recommend you could refer to

How to configure R/3 System with Load Balancing?

Hello,
I've created a Web DynPro Application and I would like to case an iView on it. According to SAP tutorials I first need to configure an R/3 System with Load Balancing.
My problem is how to configure the "WAS Host Name".
According to the tutorial:
WAS Host Name = <host>.<domain>:port (this corresponds to the Web Dynpro server location and the port on which it is running eg. PXYZ.wdf.sap.corp:50000.)
I am using NW 04 and my portal is running on this address:
http://ep6sp9test:50000/irj/portal
When I set the WAS Host Name to ep6sp9test:50000 the Test connection fails (I have privildges and created an alias and User mapping). What should I put at this field then?

Hi
I think you have to specify the HTTP port og the WAS running the R/3 system. The 50000 port is the HTTP port of your portal - not the R/3 system. You can see the HTTP port of the R/3 system using transactioncode SMICM - services in the R/3 system.

Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

David,
We've used Resonate (software) to load balance the gateways. It allows
you to group all the gateways under 1 virtual URL and load balance the
incoming connections over each gateway depending on the rules that you
define in Resonate. Look in the SUN portal whitepapers there is one that
talks about it specifically.
As far as load balancing the calls to the portals, the gateways will
automatically load balance across all the portals that they know about
using a simple round-robin rotation. You may be able to use Resonate in
front of the portals but you may need to activate persistance within
Resonate to ensure that the user always ends up on the portal that he
established his initial connection on (if you want that), check with Sun
on this one.

BM clustering with load balancing

I want to implement BM clustering with load balancing according to AppNote written by Steve Aitken from March 25, 2005.
It's clear that I need to use two private addresses (from the example, these are 10.10.10.10 and 10.10.10.11). However, I'm not sure what are IP addresses 10.10.10.1 and 10.10.10.2 used for?
Existing BM servers have two NICs: first defined as private and the second as public addresses connected directly to Internet (they are from different subnets).

What do you mean "aren't able to get out through any of the ip
addresses"?
Do the addresses show up in any of the proxy nodes with display secondary
ipaddress? Does the proxy console option 17 show the server listening on
those addresses?
Is the gateway timeout error a BorderManager (or Windows) error? If
BMgr, then check that BMgr has a correct default gateway, DNS is working
(option 4 on proxy console screen) and try dropping filters for a test.

Got it working. I noticed that my dns setting in BM2 didn't coincide with settings in BM1. So, I made them the same and reinitialized the system on both servers. Of course, when I did that, it added the secondary IP addresses. So, I'm really not sure what was stopping it from working before, unless I have something misconfigured that's preventing the secondary addresses from loading. Go figure.

OAM 11g integration with Kerberos on cluster with load-balanced virtualhost

Hello!
I need to make a Kerberos integration with OAM.
I find following notes about OAM 11g: WNA Configuration for HA Clusters [ID 1365888.1] (https://support.oracle.com/epmos/faces/ui/km/SearchDocDisplay.jspx?_afrLoop=223640518878014&type=DOCUMENT&id=1365888.1&displayIndex=1&_afrWindowMode=0&_adf.ctrl-state=14ehvbh4z2_61).
"In an OAM Clustered environment, the OAM Principal for WNA must be the same on all tiers i.e. the load-balanced virtualhost for the OAM cluster.
Therefore each OAM managed server will reference the same keytab file, generated for Principal HTTP/<virtualhost.domain>, and the keytab file will be in the same location on all OAM managed servers.
For example: ${DOMAIN_HOME}/domains/${DOMAIN_NAME}/config/fmwconfig/oam/<keytab filename>.
After copying the keytab file to the same directory on all OAM managed server machines, complete the configuration of the Kerberos authentication module in OAM Administration Console (/oamconsole).
The AdminServer will ensure that the oam-config.xml file on all OAM managed server tiers in the cluster is updated with this configuration."
The question is; When I generate oam.keytab with following command, What is the name of the server that I will must put in the command? Virtualhost (load-balanced), Node1 or Node2?
ktpass -princ HTTP/<servername>@DOMAIN -pass XXXXXXX mapuser DOMAIN\user -out oam.keytab.
Thanks in advance and best regards!
PS: Sorry if my english is not clear.

David,
Your Principal name should be the SSO LB URL.(ie :sso.mycomany.com)
ktpass -princ HTTP/sso.mycomany.com@DOMAIN -pass XXXXXXX mapuser DOMAIN\user -out oam.keytab.
Also make sure sso.mycomany.com has a reverse DNS configured correctly.
you can check using dig command
ping sso.mycomany.com
What ever the ip-address
dig -x <IP-ADDRESS>
Check in the reverse DNS section there should be 1 record.
;; ANSWER SECTION:
1.1.1.1.in-addr.arpa. 3600 IN PTR sso.mycomany.com.
Let me know if you have more questions.
Thanks

SSO with SAP R/3 with load balancing as backend over the Web AS

Hi,
we have Netweaver 2004 at this time and we have to connect the portal to a BSP application in a load balancing environment.
We set user mapping for the user and set the connection type from SAPLOGONTICKET to UIDPW. This is running for a test environment with only one R/3 system without load balancing.
Does anyone know the setting parameters for a load balancing environment (ok, the message server and...?).
Thank you.
Best regards
Patrizia

Hi all,
run into the same problem. Setting up a mapping with UIDPW in a non load balanced WEB-AS enviroment for BSP or Webdynpro for ABAP works fine. But if I go to set it up in a balanced system I can see the following behavior. The http request is send to the messageserver. This request enclosed my mapped user and password. The messageserver responds with an HTTP 301 wich contains one of my applicationservers, so far so good. The client sends a new request to the mentioned applicationserver but this time without the UIDPW. So the user will not be logged in.
I was wondering if my backend have to issue logonticket too, cause today it only accept tickets from the portal.
Is this is a bug or a feature?
Regards,
Bernd

How to configure RZ12 and SM59 ABAP connection settings when we have work with Load Balancing servers rather than a specific server .

Hi ,
If we have a specific server say 10.10.10.10 (abc.co.in) on which we are working, Then under RZ12 we make the following entry as :
LOGON GROUP          INSTANCE
parallel_generators        abc.co.in_10         ( Lets assume : The instance number is 10 )
Now in SM59 under ABAP Connections , I am giving the following technical settings:
TARGET HOST          abc.co.in
IP address                  10.10.10.10
Instance number          10
Now if we have a scenario of load balancing servers with following server details (with all servers on different instance numbers ) :
10.10.10.11
10.10.10.13
10.1010.10
10.10.10.15
In this case how can we make the RZ12 settings and SM59 settings such that we don't have to hardcode any IP Address.
If the request is redirected to 10.10.10.11 and not to 10.10.10.10 , in that case how will the settings be.

X.509 certificate based authentication with load balancer

I've been asked to implement certificate-based authentication (CBA)
on a weblogic cluster serving up web services. I've read through
Chapter 10 (security) and understand the "Identity Assertion" concept.
Environment:
Weblogic 8.1 cluster fronted by a load-balancer that handles SSL and
uses sticky-sessions.
Question:
If the load balancer is used to handle SSL, do I still need to turn
on SSL on the weblogic cluster in order to use CBA? Is there another
way to request the client's certificate?
If the above is yes, what is the minnimal level of SSL? Does it have
to be two-way?
If SSL has to be turned on is there any reason to use the load
balancer's SSL? Is there still a performance benefit?

Hi George,
If you want the client's cert, the server has to ask for it and this
implies two-way SSL. Normal one-way SSL the server provides the cert to
the client and the client decides if it wants to continue the handshake.
If the client is OK with the server certs and two-way SSL is configured
on the server, then the server will request the client send it's certs.
If the client certs are OK, then the pipe is established.
Concerning the load balancer I'm assuming it is simply providing a
tunnel, but I don't have the experience to comment and it is something I
would suggest that you that you seek guidance from our outstanding
support team [1] or drop a note in the security newsgroup [2] for the
experts to review.
