Problem Connecting to SFTP server using the SFTP Transport in OSB 11gr1

Hi,
I have a proxy service that polls for files from an SFTP server. But there seems to be some problem with the handshake between the both.
Below is the error that is logged:

I could see the same error mentioned in a couple of posts; but couldn't find any resolution to it. Any Pointers on this would really help.
Settings Done:
I have configured a service key provider.
Placed the Known_hosts file at Domain_Home/config/osb/transports/sftp with all the necessary details.
Thanks,
Manoj

Hi Manoj,
It may be an issue with Known_hosts file. Make sure that it is properly formed and it has no space/newline character at the starting of the file.

Problem connecting to Windows Server using RDC with RDP SSL on PowerPC Mac

At work we use Windows Terminal Server 2003. We have multiple Macs connecting remotely using Microsoft Remote Desktop Connection 2.0. We recently changed settings to require SSL security on all remote connections. Everything works fine with Intel based Macs, but no PowerPC based Mac has been able to connect since enabling SSL. The error message states "you have been disconnected from the Windows-based computer because there were problems during the licensing protocol."
In the Administrative tools of the Terminal Services Configuration on the server, the Security Layer is set to SSL. If we change the security layer back to RDP Security Layer, the PowerPC based Macs can connect without a problem. The Encryption Level settings seems to have no effect on the connection.
Does anyone have experience with this problem or know of a solution?
Thanks in advance!
David

Problem connecting to Sybase Server using Crystal XI-Version-11.0.0.1994

Dear All,
I have Crystal Reports XI (Version-11.0.0.1994) and Sybase Adaptive Server Enterprise 12.5 installed in my machine.
Now Im trying to connect to Sybase Server As , File > Log On or Off Server > Create New Connection > More Data Sources > Sybase. But am not Able to. It takes me to the installation wizard and ends with "No items found" error message.
How ever Im able to create an ODBC Connection to the sybase server. But I want to create a connection using Sybase Native Driver. Could you anyone please throw some light on this
Thanks

Hello,
Go into Add/Remove Programs and Change and then select Custom install and expand the database drivers. Verify you have selected Sybase, if not select it and then OK.
If it's there then make sure the client is installed and path to the Sybase Client is in the PATH statement. Sorry I don't recall what it should be but you should see Sybase there somewhere. If not add it, typically it also has a \bin folder.
Thank you
Don

How do i connect to SQL server using the JDBC ODBC

I am attempting to connect to a database on a server over a network. It is running SQL Server 2005. Am i supposed to set the ODBC on my computer or on the server computer and this is the code i am using but i keep getting a class not found exception.
//Variables for the connection to the second Database static final String JDBC_DRIVER2 = "com.microsoft.sqlserver.jdbc";; static final String DATABASE_URL2 = "jdbc:sqlserver:///*serverName*/;databaseName=Dashboard;" + "user=dashboard; password = **********"; private Connection connection2; public void Connection2() throws Exception{ Class.forName(JDBC_DRIVER2); connection2 = DriverManager.getConnection(DATABASE_URL2); System.out.println("Connected 2"); Statement statement2 = connection2.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); }
I have the server's actual name in /*serverName*/ so i know that it is not the issue i left it out for business sensitivity.
I downloaded sqljdbc.jar and have placed it both in my eclipse driver folder and in the project folder itself.
Any help would be very grateful.
Thanks Nathan M.

ODBC has nothing to do with the driver in the code that you posted.
Class not found has nothing to do with the connection string.
And the exception stack trace, if you were printing it, would make that obvious because then you would note that
it isn't getting to that line.
Class not found exception means that either your class path is wrong, which is a basic part of java not jdbc,
or that you specified the class name wrong.
I downloaded sqljdbc.jar and have placed it both in my eclipse driver folder and in the project folder itself.Apparently that isn't sufficient because it still isn't in your class path.

Problem connection to SQL Server using DG4MSQL gateway.

I am getting the following error trying to use a SQL gateway on Windows platforms:

Connection with external System using AS2/SFTP adapter.

Hi All,
I need to use SFTP/AS2 to connect to an external Server which is not in our landscape.
Can anybody could help whether i need to create a party on the Sender side as sender system is an external Server.
I have gone through many docs but i am not clear when to use party and when not..?
Regards,
Rahul

Hi Rahul
Whether to use a party or not is both an architectural question as well as a development question.
Architecturally, if an external server is not in your landscape and belongs to a different company/entity, your scenario would be a B2B process. You can refer to the below link for more details about B2B, but I've included a short snippet below too.
http://help.sap.com/saphelp_nwpi711/helpdata/en/48/c7a475da5e31ebe10000000a42189b/content.htm
Using a communication party, you address a company that is involved in a B2B process.
The (technical) name of the communication party (for example Bosch) is the identifier for the company within an Integration Directory. To be able to identify the company during any external communication using a globally unique ID, you specify alternative identifiers for a communication party. For external communication, the name of the communication party that is known internally is mapped to the ID. A particular identifier is specified in the communication channel (see below).
In terms of development, not all adapters (FTP, SFTP, SOAP, etc) require the use of a party object when you develop a B2B integration scenario. There are companies which have implemented all B2B scenarios using those adapters in an A2A style (using just Business Systems.)
As Harish has mentioned, if you use the Seeburger AS2 adapter, you will need the party object (AS2ID is configured there), but if you use the SFTP adapter, it is optional.
For your case, I'd recommend going with Party to clear distinguish that it is a B2B process.

Problem connecting to SQL Server from JDeveloper 10g using jdbc third party

I am using Oracle 10g Jdeveloper and I tried to setup a database
connection to SQL Server using various Drivers for JDBC as Merlin, jtds, inet.tds, etc.
(I had no problem to set up a connection to an Oracle Database using the
Oracle JDBC driver).
When I am testing the connection throughout the wizard, I do receive
this error message: "Unable to find driver:
com.microsoft.jdbc.sqlserver.SQLServerDriver".
I m not understanding from last 3 days where to place the corresponding JAR files so thaI may not get the Error.
When I hit n trialed at various directories of the JDeveloper as </rootDir/jdbc/lib>
</rootDir/lib>
</root/jdev/my Work/Application1/Project1/public_html>
</root/jdev/my Work/Application1/Project1/public_html/web-inf/>
when I tested the connection I do received:
"Unable to find driver:
xxx.xxx.xxx.xxxxxxx Unable to find driver:
Obviously it can't locate the Micrososft JDBC driver but I can't
figure out why.
I tried all kind of things without any success. Is somebody can help
me and took me beyond this.
I m trying to build DataSource connection from JavaBeans.
Please make me out of this cave. I m not finding any of the way to do this.
The last code I tried is
try {
Class.forName("com.inet.pool.PoolDriver");
com.inet.tds.TdsDataSource tds = new com.inet.tds.TdsDataSource();
tds.setServerName( "local" );
tds.setDatabaseName( "bluff" );
tds.setUser( dbUserName );
tds.setPassword( dbPassword );
DataSource ds = tds;
Connection con = ds.getConnection(dbUserName,dbPassword);
Statement stmt;
ResultSet rs = null;
Thanks,

you are confusing me at least as your error is discussing the microsoft driver yet you are configuring the inet datasource.
I do not use JDeveloper, but you need to make sure that whatever is servicing your web app/JavaBean has access to the driver. Not sure why you are not doing a JNDI look up of the resoure, but because you are not you can stick the driver jar in the lib directory within the WAR bundle. I would suggest that you add the driver to the lib/ext or the lib directory which is loaded at boot time for your web container and then use JNDI to look up your DataSource to reduce your coding maintenance headaches.

The easiest way would be to use Back to My Mac, but that will only work if the server is a Mac running OS X 10.7 or later and you have the cooperation of the network administrator.

I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

Installing Printers from Windows 2008 R2 printer server using the Cname

Am having issues installing printers on workstations from the windows 2008 R2 print server using the DNS names. the servername and Full qualified Name works fine.
l have tweaked the Registry and Disabled the StrictNameChecking but still getting an error. this is the message am getting...
Printer Installation Failed
You do not have enough privilege to complete the printer installation on the local machine.
I found this KB and did exactly what is in the KB but stilll....

need help

Hi.
I think I solved this yesterday. We got 1 printserver, with an alias, which we had this problem to connect to. I noticed that there is a difference between x86 and 64bits system entries in the registry...
When you are having a 64bit system, you must use REG_QWORD instead of REG_DWORD, REG_DWORD is only to be used in x86 system! See below.
Windows 2008 server R2 64-bit
HKLM\SYSTEM\CurrentControlSet\Control\Print
= ”DnsOnWire” = REG_QWORD Decimal = 1
(reg add hklm\system\currentcontrolset\control\print /v DnsOnWire /t REG_QWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters
= DisableStrictNameChecking = REG_QWORD Decimal = 1
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v DisableStrictNameChecking /t REG_QWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters\
REG_SZ = OptionalNames = “aliasname” (C-name record in DNS)
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v OptionalNames /t REG_SZ)
Windows 2008 server x86
HKLM\SYSTEM\CurrentControlSet\Control\Print = "DnsOnWire" = REG_DWORD Decimal = 1
(reg add hklm\system\currentcontrolset\control\print /v DnsOnWire /t REG_DWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\Lanmanserver\Parameters = DisableStrictNameChecking = REG_DWORD Decimal = 1
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v DisableStrictNameChecking /t REG_DWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanManServer\Parameters\ REG_SZ = OptionalNames = “aliasname”
(C-name record in DNS)
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v OptionalNames /t REG_SZ)
Don't forget to reboot your system after these changes!

Problem while sending/Receiving request using the HttpURLConnection obj

Hi,
We are facing the problem while passing the request in Weblogic.
Looks like there is some problem with Weblogic while sending/Receiving the request using the HttpURLConnection object.
Currently we are migrating 2 applications to WebLogic. Application1 to application2 request should pass.
Below is some example we tried:
"When we send a request to our code using the SSOAdaptor code (which handles the request/session in our application) which is on the SunOne server the request parameters are received by our code successfully. And also in Create User Functionality of application1 we are sending a request to webpass(which is on Sunone Server) using the HttpURLConnection object and the SOAP request is received successfully by the Webpass."
Looks like when we send request (using HttpURLConnection) from a server other than Weblogic to a servlet in a Weblogic the request parameters are received with out issues.
Where as when the request is sent from WebLogic to WebLogic the request parameters are missing some how.
Is there any issue in Weblogic? Please helpus on this.
Thanks,
Nagesh

Hi,
Please find below scenario for testing.
We have tested the SSOAdaptor code (it is the fucntion name which will send the data from source) locally by hittiing the WPS adaptor URL in a Java client program(TestRequest.java) and the request parameters were reaching the WPS Adapter successfully.
Then we have written two test servlets to test the communication between SSOAdaptor(TestServlet.java) and WPS adaptor(WPSServlet.java).
Functionality of TestSevlet: It is sending a request to WPSServelt similar to the way we are doing it in SSOAdaptor.
Functionality of WPSServlet: It will receive the request parameters and write the parameter Map to console.
We have deployed and these two servlets(in a single webapplication) on Tomcat server and the request parameters are reaching the WPSServlet successfully.
Output on Tomcat server:
before sending request
**********************Inside WPS Servlet -- the request Map is:{TypeAcc=[Ljava.lang.String;@14e3f41, ServiceName=[Ljava.lang.String;@1acd47, GMEPortalUserID=[Ljava.lang.String;@19b04e2, UserID=[Ljava.lang.String;@5dcec6, Country=[Ljava.lang.String;@b25b9d}
after sending request
After this we have deployed these two servlets (with in a single webapplication) on the Weblogic server in Dev machine(path: /apps/usmport/domains/usmport/servers/usmport_admin/upload/ssoAdaptor/WEB-INF/classes/com/gm/gmeportal/security/adaptor) and
now the request parameters are not reaching the WPSServlet.
Output on Weblogic Server:
before sending request
**********************Inside WPS Servlet -- the request Map is:{}
after sending request
Looks like there is some problem with Weblogic while sending/Receiving the request using the HttpURLConnection object.
When we send a request to WPSAdaptor using the Old SSOAdaptor code which is on the SunOne server the request parameters are received by WPS successfully. And also in Create User Functionality of Portal we are sending a request to webpass(which is on Sunone Server) using the HttpURLConnection object and the SOAP request is received successfully by the Webpass.
Looks like when we send request (using HttpURLConnection) from a server other than Weblogic to a servlet in a Weblogic the request parameters are received with out issues. Where as when the request is sent from weblogic to weblogic the request parameters are missing some how.

Encryption is required to connect to this server but the client library does not support encryption

Hi ,guys
I came cross a trouble when I configured connection encryption.
I met the following problem when I have configured connection encryption done.
Encryption is required to connect to this server but the client library does not support encryption; the connection has been closed. Please upgrade your client library. [client: ip]
environment info:
SQL:SQL2008 \SQL2005\SQL2008R2
SERVER:WIN2003 \WIN2008R2
We use C# to develop asp.net webform app, so the provider I use should be SQL client.
client .NET Framework version:NET Framework 3.5
Pls tell me why I met this weird problem.
Thanks in advance.
Love SQL

Sure,here is the connetion string of java app.
jdbc
db.url=jdbc:jtds:sqlserver://60.x.x.x./TaskSiteInfo
db.username=xxx
db.pwd=xxx
Your initial post stated you were using SqlClient in an ASP.NET 3.5 app. I think this is an issue with the jTDS client based on the error message. Are you using the latest jTDS driver? If so, try posting this issue to

Why does my computer say that there is a problem connecting to a server when I'm in iPhoto?

After I launch iPhoto, this message pops up every 10 seconds or so,
There is a problem connecting to the server "Scotts Macbook"?
Why does this happen? I'm not trying to connect to any server, how do I disconnect? I used to use the Macbook for my iWeb site, but I haven't done that for years.

I'm having the same problem. I'm running 10.7.2. My main NAS just failed and I'm using a new one. The old NAS was called "DATASERVER". The new NAS is called "NEWSERVER".
Many, but not all of my original files were located on and imported from DATASERVER which is no longer in use. I can see all of my photos but when I try to open them/edit them it's clear that I just have thumbnails. I get the error message "There was a problem connecting to a server "DATASERVER". The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
Other information:
* I'm using iPhoto 9.2.1
* Currently in Preferences I have the "copy items to the iPhoto library" CHECKED.
* I can access the directories, files, etc. on NEWSERVER via Finder.
* I have gone into keychain and deleted any references to DATASERVER
* I have turned off Time Machine.
* At one point it was asking me to find the original file and a finder window would pop up. I could then point to the original file only to get the "There wasa a problem connecting to a server "DATASERVER" again.
I do not know if I'm using a Managed Library or a Referenced Library since I set this up long ago. I seem to recall at one point I tried to manage the library myself but then changed.
Any help that you can provide would be very much appreciated. I've scoured this site and others but cannot find a solution that works.
