Data storage on a SAP WEB AS cluster environment

Hi,
We are using the SAP WEB AS 7.0 and I'm facing a problem with a single sign on (SSO) in a clustered environment.
The SSO works like this:
1. On an application outside of our WEB AS (Customer Application) a user logs on and an object called Token is send to a servlet on our application on the WEB AS (Internal Application). This Token is saved within the servlet context and contains data of the user.
2. If the user then decides to call our Internal Application, he clicks a link on the Customer Application and a second Token is send to our Internal Application. A new session in our Internal Application will be created and a search in the servlet context for the first Token for this user starts. If the first Token is found, the data from the second token will be matched with the first token.
This works fine in a single node environment. But in a clustered environment the Token objects will be spread among all server nodes because each server node holds its own servlet context. And there is my question: <b>How can I store the first Token object, so that I can reach the data within other session from every other server node?</b>
Sticky sessions are not an option, because this SSO works asynchronous and we have a session for the first Token and another session for the second Token. There are up to 800 concurrent users and the time difference between the first and the second token can be milliseconds. So Im afraid storage in the database would not work either.
I hope someone can help me with that.

Hi Nora,
When you persist the information you need in the database, you don't have a problem with multiple server nodes. Simply create a CMP EJB ("Container Managed Persistence") that holds everything you need for your single sign on. You just have to keep in mind hat you need something that does a cleanup for the data you stored in the database...
As far as I know, there is no way to deal with this issue without using a persistency layer.
Best regards,
Frank

Data storage solution for SAP BO

Hello,
Is there a storage platform that SAP prefers for Business One SQL databases? For example, Storage Area Networks? Some big storage Vendors are HP, EMC, is there a preference on which vendor and which product?
I would appreciate it if you could share any of your experience on this topic. Thanks.
Yi

Hi Yi,
I suppose this forum may not be the right place for this question since it is mostly about the SAP Business One SDK and related questions.
I propose that you contact your SAP sales representative who should forward you accordingly - or give you the information you are asking for.
I remember having heard about special offerings from hardware vendors for B1 partners customers, but I don't know about any recommendation.
If you would like to get recommendations from other partners or customers, I would suggest that you ask the question in the SAP community forum (www.sap.com/community) or the SAP Business One forum on Channel Partner Solution Network (CPSN): http://cpsn-channel.sap.com/businessoneforum

Cannot see data in SAP.Web.UI.Controls.Table

Hi,I have created a portal project and dragged a sap table into the design area. then i call a webservice and bind the resulting dataset to the table. the dataset seems to bind, since i can see there are the right number of pages in the table, but i cannot see any of the data. all the rows are blank. am i treating the ascx file correctly? i deploy and browse to test it.
this is the code in the aspx:

Hi,
The problem is that the SAP table doesn't support this kind of "dynamic binding" at the moment. The SAP table can contain any one of several controls in each cell, and these controls have several possible properties to bind to. So currently you have to "tell" the table what you want to bind to.
You have several options:
1. The easiest option, if you can create a typed dataset in design-time, according to what your webservice returns, then do that... and then put an instance of it on your portal component, and bind your table to that typed dataset (using the designer property grid). This should create a default ItemTemplate with all textViews in the cells, and the texts will be bound to the columns.
2. Write code in ItemCreated Event handler of the table. This event will be raised for each row in the DS. There you can tell the cells to get the data from the content. Remember that you'd have to create the cells according to the number of columns and set the content of each cell to be what control you want (like TextView) and then fill the properties of that control.
3. If you know the Data structure, but don't want to or can't create a typed DataSet - First define the columns using the designer (right click the table, select "edit columns"). Then in the event handler (from "2") just set the property "text" of each TextView which is in the content of each cell (use the Cell's property "TableCellContent" to get to the TextView control)
4. Don't use databinding and create the table contents completely manually (See here -
How to modify cells in a table?)
One last thing, here's a link to some more explanations about DataBinding in SAP controls:
https://media.sdn.sap.com/html/submitted_docs/PDK_for_dotNET_10/Programming%20with%20PDK%20for%20.NET/SAP%20NetWeaver%20.NET%20Controls/Data%20Binding/Complex%20Data%20Binding.htm
If you choose a solution and need more help, just ask.

Data lost in Weblogic 6.0 web server cluster

We developed a system using JSP+Servlet+Weblogic 6.0.
We use web sever cluster provided by weblogic 6.0. We implemented
a business logic to login user data. Because data user has to input is too
much, there are multiple pages for user to login data. When use finished
the first page's input, data will be posted to server and store as
attribute
object in session, and user can inut data in second page. Our problem is
when user input data in the second page, the main server is down, another
server will be become main server, however, the previous data user input
has lost. Who can tell me why, or necessary information to solve this
problem?
Regards,
Sun Gang.

In the release notes for WebLogic 6.0 it is recommended to use the

is,
however to use the weblogic.rmi.server.UnicastRemoteObject to get an RMI

But looking at the reference API for 6.0, I didn't see anywhere the

weblogic.rmi.server. The only package available for RMI in 6.0 is

SAP Data Storage Migration from HP EVA SAN to NetApp FAS3070 FMC for M5000s

Good day all
We are needing to perform a storage migration for SAP Data that is currently on 2 HP EVA SANs. We have 2 SUN M5000s, 2 SUN E2900s and a couple of V490s, that all connect to the SAN via Cisco 9506 Directors. We have recently commissioned a NetApp Fabric Metrocluster on 2 FAS 3070s, and need to move our SAP Data from the EVAs to the new Metrocluster. Our SUN boxes are running Solaris 10. It was suggested that we use LVM to move the data, but I have no knowledge when it comes to Solaris.
I have some questions, which I hope someone can assist me in answering:
- Can we perform a live transfer of this data with low risk, using LVM? (Non-disruptive migration of 11Tb)
- Is LVM a wise choice for this task? We have Replicator X too, but have had challenges using it on another Metrocluster.
- I would like to migrate our Sandbox, as a test migration (1.5Tb), and to judge the speed of the data migration. Then move all DEV and QA boxes across, before Production data. There are multiple zones on the hardware mentioned above. Is there no simple way of cloning data from the HP to the NetApp, and then re-synching before going live on the new system?
- Would it be best to have LUNs created with the same volume on the new SAN as the HP EVA sizings, or is it equally simple to create "Best Practise" sized LUNs on the other side before copying data across? Hard to believe it would be equally simple, but we would like to size the LUNs properly.
Please assist, I can get further answers, if there are any questions in this regard.

SAP Web Dispatcher in a high availability environment

Hello, guys
We are working in a CRM 7.0 implementation Project. Our system landscape is the following:
   - Two hosts (host1 & host2) on MSCS cluster (Windows 2008) with SQL Server and ASCS in high availability. Additional, this MSCS cluster has a instance of SAP Web Dispatcher.
   - In these two host weu2019ve installed a CI & DI instance, outside of high availability scope
   - Two additional hosts (host3 & host4) with one dialog instance in every host
We have severe problems with communication between SAP Web Dispatcher and ICM components. Our configuration schema is the next:
   - ASCS (MSCS_virtual_hostname):
ms/server_port_0 = PROT=HTTP,PORT=8141
SAPLOCALHOSTFULL = <MSCS_virtual_hostname>.<domain>
   - IC (host1)
icm/server_port_0 = PROT=HTTP,PORT=8040,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host1>.<domain>
   - ID1 (host2)
icm/server_port_0 = PROT=HTTP,PORT=8044,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host2>.<domain>
   - ID3 (host3)
icm/server_port_0 = PROT=HTTP,PORT=8045,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host3>.<domain>
   - ID4 (host4)
icm/server_port_0 = PROT=HTTP,PORT=8046,TIMEOUT=90,PROCTIMEOUT=600
icm/host_name_full = <host4>.<domain>
   - SAP Web Dispatcheer (MSCS_virtual_hostname):
SAPGLOBALHOST = <MSCS_virtual_hostname>
SAPLOCALHOSTFULL = <MSCS_virtual_hostname>.<domain>
SAPLOCALHOST = <MSCS_virtual_hostname>
SAPLOCALHOST = <MSCS_virtual_hostname>
ms/http_port = 8141
icm/server_port_0 = PROT=HTTP, PORT=8042,TIMEOUT=30,PROCTIMEOUT=600
wdisp/add_xforwardedfor_header = TRUE
In SAP Web Dispatcher log weu2019ve found the following error messages:
Fri Jan 28 15:45:22 2011
***LOG Q0I=> NiPConnect2: connect (10061: WSAECONNREFUSED: Connection refused)
*** ERROR => NiPConnect2: SiPeekPendConn failed for hdl 6 / sock 130060

*** ERROR => Connection request to host: , service: 8044 failed (NIECONN_REFUSED)
SAP Web Dispather is trying to connect to connect with dialog instances through , which itu2019s incorrect (ports 8044, 8045 & 8046 are opened in dialog instances, not in virtual instance). I think it should try with real hostnames (host1, host2, host3 & host4).
¡¡Please, help!! Thanks in advance

JDBC Configuration Error -- Please Help!!!!! any SAP WebAS folks

Hi,
I'm not sure what the problem is, but I can give you some basic suggestions about what you could do.
First of all, check if there are more detailed error messages available in the defaultTrace.trc file. You can open the file using LogViewer service in Visual Administrator.
Also, check the settings for Database URL, and make sure you have set the SQL Engine option in the Additional tab to "Native SQL".

Web Services Session /Singleton cluster environment

Hi!
I am having trouble figuring out how to do sessions in web services.
I am trying to build an app that uses multiple GUI's in different languages (not java) and we want to implement our business layer with web services.
I need a session to save user settings, and user info so that I can avoid going to the database and ldap in every call.
So far my idea is to have a web service that deals with the authentication. If the user is valid, the web service will save in a singleton that has hashmap the user setting and return to the client the hashmap key as a token.
The client has the responsibility to save the token and to use it in later calls.
The problem that I have is that a singleton would not work in a cluster environment! And I really don't want to be passing all the user information between calls
Any ideas how can I solve this???

Hi Gaurav,
Yes, the currently running session will be taken care of by the another server node which is up and running.
Your question: Does this mean that the a session of WebDynpro application will continue to work or the changes are lost and the user needs to login again?
"The state of the session is maintained in the persistent storage after the last successfully ended request." Which means that for example a user was filling up a form and haven't saved the changes and the server crashes then the data on that form will be lost when the second server node starts processing the request. But if the user had saved the data before the server crashes that state of the session will be stored and the data of the form will be saved and user need not fill it up again. If the Server crashes in between the HTTP request session then the request is assinged to the another server node to generate the response. In none of the case user needs to login again.
Your question: Fundamentally the question is what WebDynpro uses behind the scenes for maintaining session?
It uses Java Serialization to serialize the HTTP Sessions
"Serialization involves saving the current state of an object to a stream, and restoring an equivalent object from that stream. The stream functions as a container for the object. The information stored in the container can later be used to construct an equivalent object containing the same data as the original."

WSDL Data connection not working - SAP Interactive Forms(Adobe Based)

Greetings,
I am trying to explore the features of Adobe based forms in SAP (WAS 6.4) and have been trying to create an interactive form.
I am trying to use the WSDL file Data Connection but with no success. This is what I have been doing, starting with a blank form in the "Layout" tab,
   - In the "Data View", created a "New Data Connection".
   - Selected "WSDL file" Option.
   - Browsed to and selected the desired WSDL file.
   - Selected the WebService Option listed (Only one in my case).
The WebService in this case is programed to "Request" two numbers and "Response" back the sum. (This was just for trial).
- The connection subsequently appeared in the "Data View".
   - Expanded the "Request" and "Response" trees and dragged the elements to the "Body Page" screen.
   - Dragged the Data Connection Button to the screen.
   - On the Properties of the Button, Went to the "Object" tab and then to the "Execute" tab.
   - Checked "Re-Merge Form Data" and Run at "Client and Server"
   - Generated the PDF Preview
   - On the preview, entered the values for the "Requested" fields and clicked the button. It displays the error message "Couldn't post data to ".
This was my long story, but with this background, what I want to know is:
   - How do i get it to work, I expected to see the sum in the field.
   - What is meant by running at "Client or Server".
We do use a proxy server to connect to the Internet.
As a bottom line, I intend to make an interactive form with which I can display real-time transactional data on the form from our R/3 46C server based on a user input on the form itself (eg: PO info on entering of PO number on the form output itself)
Best Regards,
Sanyam Kapur

Hi Sanyam,
Looking for messages with zero reply I have found yours.
Even if it is some time ago, when you posted the message, I would like to give some hints here:
Web Dynpro does not allow to access data coming directly from a Web Service and display it within a pdf file. You need to create a Web Service modell first. Then you would bind the InteractiveForm property to the context and the data can be shown.
Hope that helps.
Best regards,
Karin

How to change the default operators in sap web ui Search screen?

How to change the default operators in sap web ui Search screen?
For eg. Using advance search option , I have some fields with default operators like equals, contains,is between, is less than and is greater than. I don't need all these operators for this field.
I need only "equals" operator. How do i remove the rest of the operators?

There is a view cluster crmvc_dq where all the standard setting is present related to you r issue. Please try if you can modify that, that way you will avoid the code.
Incase you are not able to make any changes there then in that case you have to redefine the method GET_DQUERY_DEFINITION () of the IMPL class to delete the operators for a particular serach field.
Regards,
Harshit

TREX - Configuring Distributed Slave with Decentralized Data Storage

I am creating a distributed TREX environment with decentralized data storage with 3 hosts. The environment is running TREX 7.10 Rev 14 on Windows 2003 x64. These are the hosts:
Server 01p: 1st Master NameServer, Master Index Server, Master Queue Server
Server 02p: 2nd Master NameServer, Slave Index Server
Server 03p: Slave NameServer, Slave Index Server (GOAL; Not there yet)
The first and second hosts are properly set up, with the first host creating the index and replicating the snapshot to the slave index server for searching. The third host is added to the landscape. When I attempt to change the role of the third host to be a slave for the Master IS and run a check on the landscape, I receive the following errors:
check...
wsaphptd03p: file error on 'wsaphptd03p:e:\usr\sap\HPT\TRX00\_test_file_wsaphptd02p_: The system cannot find the file specified'
wsaphptd02p: file error on 'wsaphptd02p:e:\usr\sap\HPT\TRX00\_test_file_wsaphptd03p_: The system cannot find the file specified'
slaves: select 'Use Central Storage' for shared slaves on central storage or change base path to non shared location
The installs were all performed in the same with, with storage on the "E:" drive using a local install on the stand-alone installation as described in the TREX71InstallMultipleHosts and TREX71INstallSingleHosts guides provided.
Does anybody know what I should try to do to resolve this issue to add the third host to my TREX distributed landscape? There really weren't any documents that gave more information besides the install documents.
Thanks for any help.

A ticket was opened with SAP customer support. The response to that ticket is below:
Many thanks for the connection. We found out, that the error message is wrong. It can be ignored, if you press 'Shift' and button 'Deploy' (TREXAdmin tool -> Landscape Configuration). We will fix this error in the next Revision (Revision 25) for TREX 7.1.
