Dynamically connecting WD Application to different backends
Hi,
A single WebDynpro Application running in the portal needs to be connected to different Clients in the backend system depending on the current logged user.
As I found out, the standard JCO Connections can be overwritten by URL parameter overwriting.
But for this I need different iViews in the portal connected to the same WebDynpro application but with different JCO Connections.
Is it possible to have one iView which does this?
Regards
MK
Hi MK,
You should create the JCO Connections manually in your WebDynpro Application.
The overhead is that you then need to manually close them as well when not in use.
Check this tutorial.

Multiple ESS's in one Portal connected to different backend systems?
Hi,
We have two backend systems installed.
We have one portal.
We want to create a second copy of the ESS Portal content connected to the the second backend.
Datawise this is not a problem.
But what about the JCo's and the Homepage Framework?
The WebDympro application seems to look for two specific JCo (for example SAP_R3_HumanResources and ...MetaData) and then both copies of ESS want to use this. Is it not possible to have each copy of ESS use it own JCo's and connect to its own backend system for the Homepage Frameworks?
Thanks,
AdriaanAdriaan,
Its NOT possible to even talk to different clients in same backend system because you cannot duplicate the JCos and while creating them you need to specify the system and client details.
Also it uses a system alias which also has to be unique.
Per my knowledge one portal instance can talk to only backend client and to talk to another backend / client you will need to create a new instance within the Portal.
This [help|http://help.sap.com/saphelp_nw2004s/helpdata/en/82/76a2406546ba15e10000000a1550b0/frameset.htm] talks sometihng on multiple backend support. I am not much aware about it but see if it helps you.

Dynamically connecting to different clusters
Hi,
Is there a way to dynamically connect to different clusters?
I have QA/Stage/Production cache clusters, and working on utility to manipulate any of those from an admin tool. For example, is it possible to dynamically attach to QA cluster, perform some operations, detach, then connect to the Stage cluster later? If so, then how to specify the configuration for the different clusters programmatically (e.g. the coherence override xml files)?
Thanks,
HarryHi,
I am having a similar problem. I want to connect to 2 different clusters, one running version 3.3.1, one running version 3.4, from the same jvm using extend. I can get the clusters to connect by using separate classloaders (the parent containing 3.3.1 and a child classloader that is overridden to look in its own classes before looking in the parent with the 3.4 classes loaded). My domain interfaces are loaded in the parent classloader so I can transport the objects around the rest of the app.
Unfortunately when I try and do anything more sophisticated than connecting (ie get, put, invoke) I get the following:
2009-02-13 08:33:54.922/2.781 Oracle Coherence GE 3.4/405 <Error> (thread=TestCache:TcpInitiator, member=n/a): An exception occurred while decoding a Message for Service=TestCache:TcpInitiator received from: TcpConnection(Id=null, Open=true, LocalAddress=147.114.128.215:1884, RemoteAddress=147.114.128.215:9300): java.io.IOException: Class initialization failed: java.lang.ClassCastException: com.tangosol.util.UUID cannot be cast to com.tangosol.io.ExternalizableLite

Dynamic Connection to different servers are not working
Hi All,
I am trying to create a SSIS Package that loops through a table containing the server names and fetching results from all the servers.
Created two variables
--list is an object
--itr is an string variable
I have created a table "Serverlist" that contains all the servernames,
and using a OLE DB connection with a property "Servername" --> user::itr. used for loop through all the servers in for Each loop.
The execution is started, showing the results for one server and failed with the below error"
"[OLE DB Source [29]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call
to the connection manager "src" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
[SSIS.Pipeline] Error: OLE DB Source failed validation and returned error code 0xC020801C."
Any suggestions are welcome.Hi,
Are you passing the correct servername, password, login, database in your connection string??
Are you getting the value at runtime?
Try this: Click on the package and on the property try to set the DelayValidation=True.
If the DelayValidation is true the package will validate the connections before it execute. If DelayValidation is false it will validate when the package is running.
So if you have a dynamic connection I suggest you set it the DelayValidation=False -
How to Use the Oracle Security (dynamic connection) ADF Struts ?
Hello All
I need to use the security from Oracle in my application, I mean I use a connection to my DB , but This connection would have to be dynamic, I have to create different users with grants to my tables , and The users would have to connect to my application directly , I read something in the forum , but I'm not sure if it's possible , because I have appmodule created and they are connected to a same user. I need this be dynamic Could I use do This?. Someone have the same requirement?. Someone can help me , pleaser, Urgent!!
Thanks all.
Regards.Hello
We were banging our heads on a similar thing, maybe this will help
We needed to convert the wrapped connection to an OracleConnection so that we could do a proxy switch, but maybe you could apply it to your situation anyway
1-you have to convert the Connection object to an OracleConnection in order to use the method that does the proxy switch
The method to do this is getInnermostDelegate()
Once you call this method, you get a new Connection object that can be cast to an OracleConnection object
See below for the snippet of code
// now switch the user and reselect
if (conn instanceof DelegatingConnection) {
properties.put("PROXY_USER_NAME","peter/peter");
oraConn =((DelegatingConnection)conn).getInnermostDelegate();
if (oraConn == null)
out.println("oraConn is null\n");
((OracleConnection)oraConn).openProxySession(OracleConnection.PROXYTYPE_USER_NAME,properties);
2-you have to put a setting in the xml file in conf/Catalina/localhost that allows you to call the getInnermostDelegate() method
By default, Tomcat does not allow you to call this method, it will always return null
You have to change the xml to allow it to return an object
It seems that WebSphere and Tomcat both frown on vendor-specific methods that do not comply with the JDBC standards, but do allow it
Here is the setting:
<parameter>
<!-- NOTE: This is necessary to enable access to the Oracle connection object -->
<name>accessToUnderlyingConnectionAllowed</name>
<value>true</value>
</parameter>
Note, this setting was also put in the conf/server.xml file
Thanks

Dynamic Connection Pool Creation Failing in a cluster

Slava,
I am working with Mike on this issue and wanted to add some moreclarifications.
We have a two server cluster where one of the EJB's on one of the Managedservers
creates the connection pool. The problem comes in when a request comes tothe
second server in the cluster. The connection pool is created by the firstserver
but it is only assigned to the first server in the targets section on theconsole.
It isn't assigned to the cluster. Is there a way to programmaticallyassign the
pool to the cluster instead of just the server that created the pool?

Hi Michael,
Could you show us the code? Without looking at the code
I can only say that JdbcServices.poolExists(someName)
returns true only in case the pool is up and running.
If the connection pool MBean was created but not assigned
a target, subsequent tries to create it would fail.

More connections in application...
Hi! I need to create more connections in my app. So I have 2 users in DB. I created two connections under Application Resources in my project. How can I say that for first AppModule I want to use one connection, but for second AppModule I want to use another connection?
Best regards, DebugerDear, John! Thanks for fast reply. So At Design time in Model project I always need to change connection properties when I need to create new EO. And I need to set each AM conn. to necessary for this AM. Hope I am right so far.
1) What conn. I need to set to Model project when I run my app.?
2) I need to change something on ViewController also?
3) Maybe it is better to create main DB user and under it create two different users with own object each. So then I can use main user in my application? Can I do that way? And what You suggest me in my problem case?
Best regards, Debuger! -

How to Call Same Adaptive RFC across different Backend R/3 Systems
Hi Everyone,
I have been troubled for the last 3 or 4 days on how I should develop Web DynPro code to call the same RFC on different backend R/3 systems. Don't really want to maintain my own Jco connects within a SAP Connector project and I don't really want to import 3 or 4 of the same models. Can someone please inform what is the best approach?
Thanks.Hi Glen,
There is one other way of doing this which needs a bit of data maintenance.
The webdynpro app will connect to one R/3 backend. In the same R/3 create RFC destinations to all others backends where the RFC's needs to be called. Create a table where u maintain for what value which backend system should be called. Add rfc_dest as an import paramter in all the RFCs in the backend system where the webdynpro app is connected and call those systems using RFC destinations.
For e.g. you have one HR system and multiple FI systems based on Company codes.
Connect your webdynpro app to the HR system. Create a table in the HR system which will contain data like given below
CoCode RFC Destination
1000 RFCDEST1
2000 RFCDEST1
In the RFC's in HR system add both CoCode and RFC Destination as additional input parameters. From the front end u can pass different values and call the same RFC's from different systems.

Trace Users Currently Connected to Application
Hi,
I want to see the list of users who are currently connected to Application.
I had set the Profile Option "Sign-On Audit" at "Form" level.
Now I am monitoring the database using "Security:Users -> Monitor" option and throuth the sql query mentioned below. I am getting different output from both the ways.
select distinct fu.user_name User_Name,fr.RESPONSIBILITY_KEY Responsibility
from fnd_user fu, fnd_responsibility fr, icx_sessions ic
where fu.user_id = ic.user_id AND
fr.responsibility_id = ic.responsibility_id AND
ic.disabled_flag='N' AND
ic.responsibility_id is not null AND
ic.last_connect like sysdate;
Please let me know how to check the users currently connected to the application and their logged in time.
Thanks and Regards
AmithAfter successfully completing the request "Purge Signon Audit" i tried to monitor the users, it shows all the users connected to the Application today. It does't display the users who are currently connected to APPS Server. This is an expected behavior since you have "ic.last_connect like sysdate;" in your query. If you want to check the users who are connect in the last in the past (15/30 minutes or 1 hour) please refer to:

Report model dynamic connection string
hi
I'm trying to build a report model,which has to connect to different database
For ex:
I've 10 different customers, and i need to connect the selected customer database,
Any thoughts how to proceed in this
Thanks
ChezhianHi Chezhian,
As per my understanding, I would try the two methods to achieve your requirement: create one report model which contains those databases or create 10 report model, the data source can connect to the corresponding model based on the user. In Reporting Services,
a report model can only map to a database. So the first method doesn’t work. If we want to connect to a report model, we should browse to a report server or SharePoint site and select a published model. We don’t need a connection string to use a report model
as a data source. So the second method still doesn’t work.
To work around the issue, I think we can create 10 report model, each report model corresponding each user’s database and named the user name. Then set Item-Level Permissions of each report model based on the user on report manager. Each user can only see
his own report model on the report server.
Or we can create a data source with dynamic connection string, the blog below is for your reference:
http://blogs.msdn.com/b/bimusings/archive/2006/07/20/673051.aspx
References:

Setting Item-Level Permissions on a Report Server
Hope this helps.

Crystal Report Dynamic connection issue ORA-04043 Database Vendor Code 4043
HI All,
Ii am getting dynamic connection issue with Crystal Report 2008 and Business View Manager, i have Oracle database,
i have done following steps
1 Creating Dynamic Connection (including two connection XDC & YDC)
2. Creating Data Foundation (Common object available in both connection ie. stored procedure)
3. Creating Business View (with selected number of elements in business element, like firsta name, lastname)
I have verified database connectivity from Business view manager, both the connection are working fine bringing different number of rows from two different schemas (different schema but same objects in two schemas)
4. Database connectivity to different database schemas
5. Connectivity from Crystal Report (done the connectivity from the repository to business view )
6. Report Connectivity with first schema shows records
7 Report Connectivity with second schemas shows error
as follows Failed to retrive data from the database & on clicking of detail i get following error
Crystal Reports
Database Connector Error: 'ORA-04043: object HR.EXCEPTION_REPORT_SUB1_PROC [Database Vendor Code: 4043 ]'
Q first of all i need to know if dynamic connection using business view manager and crystal report technically possible or not, if yes then please let me know the solution, since we did verified with SQL database and ite work with two different database.
Q if not possible then are there any options to resolve dynamic deployment of crystal report over multiple schemas with crystal report 2008
Any help or suggestion will be appriciated, hope some one might have got similar issue
Thanks in advance

Edited by: smunir on Jul 12, 2011 9:43 AMHi,
When i use same credentials in Tod or sqlplus it works perfect and gives appropriate results. But when i use same credentials using business view manager, the very first connection works but the second connection does not work
Please suggest!

Hi. I'm having trouble building an application which does text processing. The application is structured as a pipeline with data flowing through a chain of modules. Each module is constructed with a java.io.Reader and java.io.Writer and the module reads from the Reader, does some processing, and writes to the Writer. For a module in the middle of the pipeline, the Reader and Writer are actually a PipedReader and PipedWriter which connect a PipedWriter and PipedReader respectively in an adjacent module.
The problem is that I want to be able to add and remove modules during runtime but the PipedReader and PipedWriter classes only allow you to connect them once. You can't disconnect them and reconnect them in new configurations. So what do I do? I need something that allows me to read from a changing Reader, either a dynamically connectable pipe or something like a BufferedReader except that you change the Reader that it reads from at runtime. Do any know of a solution?
Thanks. EliTake a look at FilterInputStream and FilterOutputStream. You can extend those, and then furnish addPipe() and removePipe(). This would be custom functionality. Maintain the list of streams each module is outputtting in a Collection. It would be relatively easy to create a Tee (one FilterOutputStream writing to multiple nested output streams) but harder to do so on the input stream end.

How to use one dynamic connection managers for multiple parallel data flow tasks
hi there:
I have 6 databases residing on the same server. What I want to do is call a store procedure with identical name on each database dbo schema and transport results to a centralized place. The key is to have those SPs run in parallel instead
of in sequence as each SP may take around 10 mins to finish.
The simplest way is to create 6 OLE DB connection managers and create 6 DFT tasks. However, I do not want to maintain 6 OLE DB connection managers as there is a chance to have more connection managers.
What I did so far is to create a OLD DB connection manager and use expression to set up connectionString properties so that it will get populated by variables at run time. It is fine when running all SPs in a Foreach Loop Container. However, it takes
around 60 mins to finish.
When I try to run it in parallel ( basically created 6 DFTs but use only one Dynamic Connection Manager), the connection string gets confused therefore all DFT tasks failed.
Does anyone here have some experience on this topic?
Thanks

--Currently using Reporting Service 2000; Visual Studio .NET 2003; Visual Source Safe SSIS 2008 SSAS 2008, SVN --Yes, basically, on the connectionString property of ONE OLEDB, you are using an expression to supply value and this expression is pointing to a variable.
In this case , you can update this variable from a table which contains many connection strings. It's good if you want to execute Store procedures in a sequential order. When in parallel mode, this will cause issues as connectionString gets overwritten.
I am thinking about using script task to exec sp.
The whole idea is that I do not want to maintain a large number of Connection Managers.
Hope it helps

So you are not able to run parallel executions using same conn mgmr, even with dynamic connectionstring, is that correct? Yes, script task will be a way to go if you wish to execute it in parallel, you may connect to SS and query the proper conn string with
SELECT/WHERE clause in each script > pass it to a script variable > use that script variable and execute the proc. This will require only two things to change in each script, the WHERE condition to get the conn string and the proc name (you may even
get the proc names the same way you get conn string) and everything else will be same. Let us know how that goes.
Hope no two or more procs doing insert/update/delete on the same tables. -
I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC). First of all, it works fine as long as the connection string is inside the App.Config file. But when I try to build it dynamically in the C# code (or rather, statically at the moment) it fails. I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works.I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC).
