Exception:'NetworkAdapter fails'when connecting with oracle from web dynpro

Hi,
I am trying to run one of my application in SAP netweaver Studio(webdynpro).
I want to connect to the oracle db on my local system.
I wrote the code:
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection cn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:DSNname","UsrId","password");
I am getting the following error in the connection statement
Error:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
Oracle is 9.2.0.1.0 on windows XP platform.
I can do an SQLPLUS and the connection is ok.
I don't know were the problem is ?
Can any body help me out.
Thanks
Smitha

Hi,
For the error "The Network Adapter could not establish the connection" check and do the following:
In the Computer Management - Services, check if the Oracle*TNSListener is started. If not, restart the listener and set the Startup Type to "Automatic".
Also check whether the port number in listener.ora is correct ($ORACLE_HOME\network\admin\listener.ora) and updated during the installation.
For other details run through SAP Note 786673
Hope this helps.

Connecting to SAP from Web Dynpro

Hi,
I am new to web dynpro, but have downloaded the java sneak preview edition and worked through it a bit. I understand that we have to use JCo to connect to SAP from Java Web dynpro, . Is it true?
What about web dynpro for ABAP? Can we use normal select statements to connect to SAP? How is it exactly done in that case?
Thanks in advance
PG

hi pg
Just go thru this example which describes how to connect to SAP from web dynpro application.

"UnknownHost" exception while connecting to mysql from web dynpro

Hi
I am trying to connect to Mysql 5.0 database from web dynpro application.I am using NWDS 7.1.
I have followed this blog and created the datasource in NWA.
https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/8675
I have written the following code in my web dynpro application.
InitialContext ctx;
       try{
            ctx=new InitialContext();
            DataSource ds=(DataSource)ctx.lookup("jdbc/dbconnect");
            Connection conn=ds.getConnection();
            wdComponentAPI.getMessageManager().reportSuccess("connected");
            Statement stmt=conn.createStatement();
               String query="select Col from TestTable";
               ResultSet res=stmt.executeQuery(query);
               while(res.next())
                    String str1=res.getString(1);
                    wdComponentAPI.getMessageManager().reportSuccess(str1);
          }catch (Exception e) {
               wdComponentAPI.getMessageManager().reportSuccess(e.getMessage());
               // TODO: handle exception
But I m getting the following error as "UnknownHost exception"
I checked with the datasource created in NWA.Here in the Driver status it is showing the driver as unknown.
I have added the following driver.
mysql-connector-java-5.0.8-bin.jar
Any idea on how to solve this problem?
Do I need to add the driver in my application also.
Thanks in advance,
Sumangala

Hi,
Have you created a datasource in Visualadmin?
Was that tested and was it success full?
If you havent done this this could be your issue
make sure the following code is using the correct datasource
DataSource ds=(DataSource)ctx.lookup("jdbc/dbconnect");

Failed to connect SQL Server from Web Analysis

Hi,
I am not able to connect RDBMS-SQL Server 2000 SP3 from Web Analysis 9.3. I have installed JDBC driver for SQL Server 2000 also. Also defined CLASSPATH environmental variable for MSSQLSERVER.jar file. I am creating JDBC drive as: -
Driver Type: Microsoft SQL Server
Database Connection String:
jdbc:microsoft:sqlserver://CNOIA258:1433;DatabaseName=biplus;SelectMethod=cursor
JDBC User: biplus
JDBC: biplus
I am getting error "Getting Connection Failed"
Please suggest any solution to resolve this issue.
Regards.
Atul K

Hi Atul
I think you need to amend the standard strings as follows:
hyperion.jdbc.sqlserver.SQLServerDriver
jdbc:hyperion:sqlserver://CNOIA258:1433;DatabaseName=biplus;SelectMethod=cursor
This has always worked for me, hope this helps

Failing to connect to Oracle from Crystal Reports

We have a client attempting to connect to 10g using crystal reports. They are getting ora-08001 as an error reported to them. Any ideas what could be causing this?

I don't know Crystal Reports and what it sends to and requests from the database, but that's the formal description of this error:
Error: ORA 8001
Text: maximum number of sequences per session exceeded
Cause: An operation requested a resource that was unavailable.
The maximum number of user sequences per session is specified by the
initialization parameter DC_SEQUENCES.
When this maximum is reached, no more requests are processed.
Action: Try the operation again in a few minutes.
If this error occurs often, shut down Oracle, increase the
DC_SEQUENCES parameter in the initialization parameter file, and
restart Oracle.

"User authentication failed" when connecting with Visual Administrator

Hello,
I am having trouble making a connection to my local J2EE Engine using the Visual Administrator (VA).
I open the VA interface and create a new connection. The default User Name is "Administrator". I put in "localhost" for host, "50004" for port and leave the Transport Layer selection to "Default".
When I try to connect this way I get the following message:
User authentication failed
Next I went into Start|Settings|Control Panel|Users and Passwords and saw that there were several ids created by the Developer Workplace (DW) installation. The ids that I see are: j2eadm,sapadmin,sapinstall and SAPServiceJ2E
I checked all of them to see what groups they're members of and they're all at least members of "Administrators" group.
There are also 3 new groups that must have been created by the DW installation: SAP_J2E_GlobalAdmin, SAP_J2E_LocalAdmin and SAP_LocalAdmin.
The j2eadm id belonged to all 3 new sap groups so I changed its password to something I'd remember and then changed the connection to use that login.
When I tried to connect thru VA using this id and the new password I still get the "User authentication failed" error message.
Can anyone please tell me what I'm doing wrong?
Thanks in advance for any help.
David.

Hi,
During the installation the SAPINST asks for a Administrator Password.. This password is very important.
We had kept same passwords for all userids to start with.
This helped reduce lot of confusion.
Warning: if you enter the wrong password 5 times, the userid 'Administrator' gets locked.
However there is an Emergency password recovery procedures.

Error connecting to Oracle from when running SSIS Package on Windows 64-bit

When I execute this same exact package as a SQLAgent job 32-bit (type Operating System CmdExec) it runs successfully. When I run the package using the Execute Package Utility, it runs successfully. When I am editting the package in BIDS I can connect to Oracle. For both 64 and 32 bit, I use a dtsconfig file which specifies the Oracle connection string and password.
Someone mentioned on another forum that maybe there is no Oracle ODBC driver for 64-bit Windows. I would assume that the OracleClient 64-bit would include that.
I hope I have included all info needed. Please let me know if you may have a resolution to this problem.
Thanks.

I was trying to transfer data from oracle to sql server 2008 on a daily basis.
I have very hard time connecting to oracle from ssis package on windows server 2008. I am almost dead and cannot find any help. i was able to connect to oracle using import/export 64 bit feature of SQL Server 2008 using Oracle provider for OLEDB. But I am not sure why the same does not work with BIDS?
Here's the environment info:
1. Oracle Client 10g
2. SQL Server 2008
3. Windows Server 2008
Appreciate your help. Please save me.

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

"stack overflow" when trying to connect with Oracle ODBC

Hi,
I'm trying to connect to Oracle DB (8.1.7.3.0) from WinNT 4.0 SP6 with Oracle ODBC driver 8.0.6.6.0. I've been trying to connect with "Oracle ODBC Test" and with "MS Query". In either way I end up with Dr. Watson reporting about "stack overflow". Before starting to upgrade ODBC driver I wanted to ask - should these versions of driver and DB work together at all (even unofficially)? Or may I be missing some other thing? Any hints, ideas are welcome.
Regards,
Madis Priilinn

Thank You for replying, Justin!
Yes, I can connect successfully to the database through other tools - at the moment I tried SQL*Plus, Net8 Easy Config and Schema Manager.
The Oracle client in the NT machine is 8.0.5.0.0. And unfortunately I do not know anything about the Oracle installation on this machine and at the moment I don't have that person near me too whom to ask also. But I think the installation was ok, because the connection through ODBC was working before the DB upgrade as far as I understood (sorry, again at the moment I don't know what was the previous version of DB. I will ask that information as soon as possible).
The main problem that bothers me at the moment is that I can't install 8.1.* series OraODBC driver with 8.0.5.0.0 Oracle Installer. I managed to install 8.0.6.6.0 version of the driver, but not the newer ones. As far as I've understood I have to upgrade the whole Oracle in the NT machine to upgrade that installer. Am I correct?
Regards,
Madis Priilinn

RPE-02150: Failed to connect with user... when deploying location

Hello.
I've created cube and 3 dimentions in OWB 10.2, then derived them to make business definition for Discoverer 10.1.
When I try to deploy this business definition, I get error "RPE-02150: Failed to connect with user xxx, password ***, connection null. Disco export file 5039.eex written to directory owb/deployed_files." The error appears at deploying location step. What feature is that?
Thanks,
Evgeni

Hi,
same situation, same behaviour. I've seen, that the location for the discoverer could only be of type 10.1 database in the lov of the location form. But the database is 10.2. Perhaps that might be the problem.
Do you have any other suggestions?
