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

Load-balancing and fail-over between web containers and EJB containers

When web components and EJB components are run in different OC4J instances, can we achieve load-balancing and fail-over between web containers and EJB containers?
null

It looks like there is clustering, but not loadbalancing available for rmi
from the rmi.xml configuration. The application will treat any ejbs on the
cluster as one-to-one look-ups. Orion will go out and get the first ejb
available on the cluster. See the docs on configuring rmi.xml (and also the
note below).
That is a kind-of failover, because if machine A goes down, and the
myotherAejbs.jar are on machine B too, orion will go out and get the bean
from machine B when it can't find machine A. But it doesn't go machine A
then machine B for each remote instance of the bean. You could also specify
the maximum number of instances of a bean, and as one machine gets "loaded",
orion would go to the next available machine...but that's not really
loadbalancing.
That is, you can set up your web-apps with ejbs, but let all of the ejbs be
remote="true" in the orion-application.xml file:
<?xml version="1.0"?>
<!DOCTYPE orion-application PUBLIC "-//Evermind//DTD J2EE Application
runtime 1.2//EN" "http://www.orionserver.com/dtds/orion-application.dtd">
<orion-application deployment-version="1.5.2">
<ejb-module remote="true" path="myotherAejbs.jar" />
<ejb-module remote="true" path="myotherBejbs.jar" />
<ejb-module remote="true" path="myotherCejbs.jar" />
&ltweb-module id="mysite" path="mysite.war" />
... other stuff ...
</orion-application>In the rmi.xml you would define your clustering:
<cluster host="230.0.0.1" id="123" password="123abc" port="9127"
username="cluster-user" />
Tag that is defined if the application is to be clustered. Used to set up
a local multicast cluster. A username and password used for the servers to
intercommunicate also needs to be specified.
host - The multicast host/ip to transmit and receive cluster data on. The
default is 230.0.0.1.
id - The id (number) of this cluster node to identify itself with in the
cluster. The default is based on local machine IP.
password - The password configured for cluster access. Needs to match that
of the other nodes in the cluster.
port - The port to transmit and receive cluster data on. The default is
9127.
username - The username configured for cluster access. Needs to match that
of the other nodes in the cluster.

Load balancing and HA for office web apps server Lync 2013

Hi,
I have 12000 users, 3 FE servers in a pool, 2 edge server in a pool, HA required, IM/presence, A/V, WEb conferencing required. plan to have 2 office web apps server a farm with HA, below are my queries
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?

Hi,
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
WebApps runs on https and you cannot load balance http traffic using DNS load balancing. you need to have a HLB.
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
you can use the same HLB for that
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?
for that one, you probably need a separate HLB.

          So do i must use it or not???
          2. When i don't use "<home-call-router-class-name>common.QARouter</home-call-router-class-name>"
          , there's no exception
          but load balancing does not happen. According to the document , there's must load
          balancing when i call home.create() method.
          my client program goes here
               DBStateful the_ejb1 = (DBStateful) PortableRemoteObject.narrow(home.create(),
          DBStateful.class);
               DBStateful the_ejb2 = (DBStateful) PortableRemoteObject.narrow(home.create(3),

          the result is like that
               the_ejb1 = ClusterableRemoteRef(203.231.15.167 weblogic.rmi.cluster.PrimarySecon
               daryReplicaHandler@4695a6)/397
               the_ejb2 = ClusterableRemoteRef(203.231.15.167 weblogic.rmi.cluster.PrimarySecon
               daryReplicaHandler@acf6e)/398
               or
               the_ejb1 = ClusterableRemoteRef(203.231.15.125 weblogic.rmi.cluster.PrimarySecon
               daryReplicaHandler@252fdf)/380
               the_ejb2 = ClusterableRemoteRef(203.231.15.125 weblogic.rmi.cluster.PrimarySecon
               daryReplicaHandler@6a0252)/381
               I think the result should be like under one... isn't it??
               the_ejb1 = ClusterableRemoteRef(203.231.15.167 weblogic.rmi.cluster.PrimarySecon

               daryReplicaHandler@6a0252)/381
          In this case i think the_ejb1 and the_ejb2 must have instance in different cluster
          server
          but they go to one server .
          3. If i don't use      "<home-call-router-class-name>common.QARouter</home-call-router-class-name>",
          "<replication-type>InMemory</replication-type>" then load balancing happen but
          there's no fail-over
          So how can i get load-balancing and fail over together??

Can I create a site proof in Muse and share it with a client over the web?

Ideally I'd share the site proof with Creative Cloud. Any feedback is greatly appreciated, thx!

Hi Tommy,
Yes, you can create a site in Muse and publish it to business catalyst. It will be in trial mode and your client will be able to view the site over the web.

Update to IOS 6 has been a nightmare. Facebook would allow me to save pictures unless I granted access to my foto album. Does this mean my pictures are going be planted all over the web? The safari keeps crashing and loading is slow.

Back up all data.
Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

Export Release Build Flash Builder 4.5 fails to load over the web.

Exported Release Build Application fails to load over the web. You can reproduce using the following steps:
1. Create New Flex Project in Trial Flash Builder 4.5.
2. Use the default Flex 4.5 sdk.
3. Configure as a web application.
3. Place the following MXML code in the main application file:
<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"
xmlns:s = "library://ns.adobe.com/flex/spark"
xmlns:mx = "library://ns.adobe.com/flex/mx"
minWidth = "955"
minHeight = "600">
<fx:Declarations>

</fx:Declarations>
<s:TextArea text = "Hello World!" width = "100%" height = "100%">
</s:TextArea>
</s:Application>
3. Save the main application file and Export Release Build to bin-release.
4. Place all files in bin-release on IIS web server in a web accessible location.
5. Go to the web accessible location in any browser with newest flash player and view the application's html page.
Actual Results:
Flash movie appears blank. Context menu shows Movie Not Loaded. Network traffic shows application main swf downloaded. Framework dependent swfs not downloaded.
Expected Results:
Movie loads. Hello World! appears in text box. Context menu does not show Movie Not Loaded. Framework dependent swfs downloaded.
Workaround (if any):
Deploy on an Apache web server.
The tests were run on IIS 7.x (7.0 for one, and 7.5)
Flex application was built using Flex 4.5.0 SDK pre-bundled release (built-in flex 4.5 with Flash Builder 4.5 trial) on Mac OS X 10.6.7 (10J869)
Flash Player 10.3.181.14
Example failing website:
http://staging.ibenergy.com/Test.html
Any idea as to why my exported release build fails? Any help would be appreciated.

Just tried this out on an IIS server with Flash player 10.3.181.14 - it worked.
Are you using the release version of Flash Builder 4.5 with the release version of Flex SDK (not a prior SDK build)?
The URL you mentioned gives me a 403 forbidden error.

How to load/save a file in the WEB-INF?

how can i load and save files in the WEB-INF directory using servlet?

This doesn't save files. And in order to reuseability and maintainability, I'd rather use java.io and passing the path/filename around in File object.
You can retrieve the absolute path for "/WEB-INF" byString absoluteWebInfPath = getServletContext().getRealPath("/WEB-INF");Then you can use that to read/write files.
File file = new File(absoluteWebInfPath, "filename.ext");
InputStream input = FileUtil.read(file);
FileUtil.write(file, input);and so on.

Cisco 2811 Router with 3 ADSL card and load balancing

Dear All,
I have few queries:
1. Does Cisco 2811 Router support 3 ADSL card?
2. We are the ISP. I want to do load balancing with 3 dsl
line on Cisco 2811 Router.
Please send me the linke for this configuration.
Thanks/Regards
Atul

hi
In 2811 you have 4 HWIC and 1 NME you can install 1-port ADSL WAN Interface Cardon the HWIC slots.
Also just enable 3 default (equal cost) routes towards the interfaces which will take care of the load balancing.
if you need more info and inputs do post out with ur requirements along with network topology in place at present..

SAP GLM Print Request - Load Balancing of WWI server

Hi GLM Experts,
I am using new GLM + module that generates labels based on Print Requests. I am unable to understand how I can load balance the WWI services when there are multiple label printing requests.
In GLM + we associate a WWI to a Print Station and which can then be associated with a printer. So in the configuration we are tying up a printer a WWI.
Also during label printing, if the scenario uses print request module, then the use need to select a print station and printer. What happens if the WWI related to the print station is down?
For example I have two services in WWI server GENPC1 and GENPC2. I created WWII and WWI2 as two print stations. I will associate my printer PRNWWI to both the print stations WWI1 and WWI2.
During label printing if the user picks and WWI1 and Printer PDNWWI and if the GENPC1 WWI server assocaited with print status WWI1 is busy and down I want WWI GENPC2 to generate the label?
How to setup the above load balancing or fall back? Please let me know.
Thanks
Pugal

Dear Pugal
we are not using GLM + and I am not sure about the technqiue used there to handle load balancing. Regarding general WWI setup I assume you know this Note: EH&amp;S: Availability and performance of WWI and Expert servers
On the top there is a further SAP Note abvailable which might be of interest. This is referenced here:
http://de.scribd.com/doc/191576739/011000358700000861002013-e
May be check OSS note: 1958655; OSS Note 1155294 is more related to normal WWI stuff; but may be check it as well. May be 1934253 might help better
May be this might help.
C.B.
PS: may be check as well: consolut - EHS_MD_140_01 - EH&amp;S-Management-Server einrichten
The load balancing of synchron WWi servers is donein the "RFC" layer, therefore you have no inffluence here, for asynchron WWI servers you can do a lot to manage the WWI load balancing by using "exits" etc.

Business Objects XI 3.0/3.1- Connection with SAP ERP not with BW

Hi all members,
I have to confirm that can we connect "SAP Business Objects XI 3.0 or XI 3.1" with SAP ERP.
My client does not have SAP Business Warehouse. Neither they are interested to have SAP BW.
So, I have to confirm that can we connect "SAP Business Objects XI 3.0 or XI 3.1" with SAP ERP ?
Any other thing i have to go for?
Kindly any member guide me in bit detail.
Thanks and Best Regards,
Izhar

Hi,
currently it is not possible to build web intelligence reports fetching data directly from an SAP ERP system. The reason is that SAP ERP data sources are not supported in universes.

Stratos
PS: An option is to deploy a BOBJ rapid mart. Please note that in this case you require the BOBJ Data services (ETL) tools. The idea behind the SAP ERP related rapid marts is that in the first step the data are extracted from your SAP ERP sources and load them into a relational database (using a predifined DWH scheme). Additionally the package provides you with universes (which rely on this predefined DWH scheme) and use the database as data sources, here your SAP ERP data were extracted to.

SAP Sourcing 7.0 integration with SAP ERP - issue with SAP PI

Hi All,
We are integrating SAP Sourcing 7.0 with SAP ERP 6.0 with SAP PI 7.1 in middle. So the Sourcing will talk to PI and this intern will talk to ERP. Sourcing is on oracle 11g where as PI and ERP are on SQL 2008. All these 3 are on windows 2003 x64.
We are following the "Configuration Guide Integration of SAP ERP and SAP Sourcing 7.0" provided by SAP.
We have successfully configured Sourcing and PI systems as pe the document. In Sourcing, by using background jobs we are able to successfully generate files in "export" folder which is part of FTP directory.
However the issue is with PI, we configured the "configuration scenerio" in Integration builder and point all channels to the FTP folder in Sourcing. But PI is not picking up these files.
Is there any way to trigger this in PI system. Or do we need to do anything in sourcing itself.
Regards,
Siva.

Hello Siva,
I am thinking that you may need to deploy FTP adapter in PI to get this process work fine but not sure.
Let's see what other experts suggest.
Thanks,
Siva Kumar

Hello Gurus
I need take a decision about use or not SAP WebDispatcher for a large customer. We estimated the numbers for the service in more than 4000 hit/sec. How I can compare the service level and features or both solutions?

would be greatly appreciated!

Hi MS DEF,
A second network adapter is required to provide peer-to-peer communication between cluster hosts. Please isolate your heartbeat network. With unicast when cluster is connected
to a switch, incoming packets are sent to all the ports on the switch, which can cause switch flooding, please confirm you have setup your switch correct, you can refer the following Cisco Switch related unicast configuration.
The Cisco switch unicast related information:
