Remote Hosting SAP

Hi
We currently run SAP internally but there is a project to host SAP externally. Has anyone got any advice on doing this or any contacts that offer hosting.
One area we need to look at is the network bandwidth, I have read the SAP documentation about this but would like some real life examples of bandwidth to the hosting site to our site with about 400 users, running EEC6 and plans to run BI as well.
Any advice would be helpful.
Thanks
Barry

Sap J2ee is instaled on remot host

Hi,
I'm work in a proyect with a page web in html,in Sap netweaver developer studio(eclipse) and i like insert date in a database that it is on remot host. How I can to make?
Thanks.
excuse me for my english

ok, it depends
of what?
of where is the database?, in case of the database is in the same web server then you can use the timestamp of the server in your sql Statement, or in the case if your Database server resides in another server then y suggest you the posibility to create an Java RMI class that lives on the database server and then call it.
(or a servlet if you wisht to use a web container).
Greetings

Connection to remote host in NWDS preferences (SAP Instance not reachable)

Hi Experts
I am trying to connect to a SAP Web AS running CE 7.1 with Netweaver Developer Studio as described [here|http://help.sap.com/saphelp_nwce10/helpdata/en/46/9ca4cf4e8b0487e10000000a1553f6/frameset.htm].
The u201Cinstance hostu201D is a remote host. When I try to connect with NWDS 7.1 SPS 5, I get the error message:
SAP Instance is currently not reachable. Check if the SAP Instance number is correct.
However, with NWDS 2004s SPS 13 (installed on the same machine) and message server port 3901, I can see the host in the J2EE view with two green dots (icm, server 0) and one grey dot (debugproxy). NWDS seems to connect (in spite of the grey dot).
Do I have to configure anything else in NWDS (message server port)? Does the debugproxy have to be started?
Thanks for helping!
Kind regards
Bettina

I had the same issue and resolved by adding:
(1) Windows server firewall exception to include "D:\usr\sap\CE1\SYS\exe\uc\NTI386\sapstartsrv.exe" EXE.
Basically, the windows server on which SAP NetWeaver CE 7.1 was installed, by default, BLOCKS all relevant ports:
50000-50020 & 50100-50120. By add the above (a) rule, the serrver allows any incoming TCP connections used by "D:\usr\sap\CE1\SYS\exe\uc\NTI386\sapstartsrv.exe."

Hi,
MSHOST=logon**.*.com is name server, but it can be recognized as in message is also part "on local host with Unicode ERROR partner '.*..**:" where *.*... is IP address..
That problem occurred after some patches were implemented.

Remote host supports the use of SSL ciphers that offer weak encryption

Dear All,
Our Internal security audit suggests to avoid the use of Week SSL ciphers for our SAP PI 7.0 servers.
We have followed the SAP note 510007 - Setting up SSL on Web Application Server ABAP
as mentioned in the point 6 we have added below parameter in the instance profile of application server and restarted our server but still the issue is not resoved.
ssl/ciphersuites=MEDIUM:HIGH:EXPORT:!LOW:!eNULL
Clients are accessing our PI server through SAP Web dispatcher.
Kindly suggest the action to be taken to resolve the issue.
Please find the below comment from Audit.
The remote host supports the use of SSL ciphers that offer weak encryption.
Note: This is considerably easier to exploit if the attacker is on the same physical network

Lalitha.

Connection closed by the remote host

Hello everyone.
I'm getting this problem in XI:
When a NON-SAP system is sending messages to XI via HTTP protocol (SOAP adapter), we are getting this error:
"An existing connection was forcibly closed by the remote host"
The guy from the non-sap system (Real Estate) got this error when he is sending a big amount of data.
When the amount data is reduced, this problem is not happening, so all messages passed ok.
In the other case, he needs to send them in batches.
We are trying to find out where the problem is.
Has anybody any idea of this?

SOAP: call failed: java.io.EOFException: Connection closed by remote host

Hi folks,
my friday crusher:
We have a sync RFC-PI-SOAP scenario.
All is working fine in Dev system.
After moving into Test following error is displayed as the SOAP response message:
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

Also Channel Monitoring says:
Message-Verarbeitung fehlgeschlagen. Grund: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.EOFException: Connection closed by remote host.
Couldn´t find any hints in SDN and the web to this issue.
Does anyone of you has made experiences with that problem?
Maybe it´s a system parameter for time out SOAP connections....?
Many thanks for your help
-and-
have a great weekend!
Cheers
André

Very strange!
But I have the solution:
I have looked into channel monitoring / RWB again.
There I saw, this PI is using two clusters on two application servers.
Everytime the SOAP call is executed through the frist cluster, all was fine.
But no SOAP call was successfully executed by the second cluster.
Fortuity? No!
The second cluster node / app server wasn´t registered for internet access in the used proxy server.
So it wasn´t an PI issue.
Now, all is fine & I´m happy!
Thanks @all for helping!
Cheers,
André

Now, i need to configure its Introcope agent for JAVA system in sOlution manager. when i go to RCA->MAnaged system->setup wizard, it successfully configures it in further screens.
However, wehn i go to RCA->MAnaged system->INtroscope agent and select the respective JAVA SID for which I installed sMD agent, it does not display the server node of jAVA for that system. Also when I check in the logs of sMG agent in the managed system, I get the below error;

Hi Guilherme,
Thanks for your reply.
I have checked in agent administration screen. The agent is successfully assigned. I only see a problem while solman talking to the managed system on P4 port. I believe I have to open or do some administration of this P4 port. But where I am not sure.
I mean while installed another SMD Agent on another J2EE server and it worked instantly!
Can you help?

I guess, that you have Java proxy libraries in the EAR file. Remove them before deploying.

A remote host refused an attempted connect operation

I have been tasked with putting together a demo of Adobe Interactive Forms on our development system, and I'm following the steps listed in the SAP How-To guide, "How To... Create Online and Offline Forms in Web Dynpro for Java."
The demo form (as described in the How-To) has been created and deployed from a NetWeaver 2004s to our Application Server 6.40 (with all the latest patches). When run, however, I get a 500 Internal Error:
      <b>java.net.ConnectException: A remote host refused an attempted connect operation.</b>
Our BASIS team has confirmed that ADS is configured correctly on the server, per SAP Note 944221.
Any suggestions on the cause and possible fixes would be greatly appreciated.

Hi Nick,
Can you verify the ADS connection using the web service test tool? Go to http://myhost:50000/, choose web services, choose the 1st one (Adobe Document Services?), choose test, don't enter any values (leave the default values) and choose test (or something very similar, I don't have access to a server right now to verify it). You should get a login screen where you need to login with "ADSUser". Finally you should see the request and response where the response status code must be "200 OK" (and the response content-type should not be text/html; that's when a logon screen html page is returned, e.g. if the password is expired).
If it fails somewhere, try it again using the FQHN, e.g. http://myhost.mydomain.com:50000/ (I think we had a similar issue once).
If the web service test doesn't work, there's definitely a problem with the ADS configuration. If the web service does work, check the connection settings in Visual Administrator <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/43/f3fcf604777062e10000000a1553f6/frameset.htm">Setting Up Basic Authentication in a Java Environment</a> (or the ABAP and/or SSL version of the same document).
Kind regards,

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;
using System.IO;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Diagnostics;
using System.Linq;
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;
try
listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
LoggingProvider.Logger.Info("This is what the host sent to you: " + input+". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
break;
catch (Exception ex)
LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
break;
}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!
Javier
En caso de que la respuesta te sirva, porfavor, márcala como válida
Muchas gracias y suerte!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
catch (Exception ex)
//LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
Please try it. For this error message, I suggest you could refer to this thread (http://stackoverflow.com/questions/6173763/using-windows-azure-to-use-as-a-tcp-server

Unable to delete file on the remote host

Hi,
I tried to delete a file on the remote host using File.delete method as well as using Runtime.getRuntime.exec("del filename")
But both of them failed to work. First one returned false, but the second one is throwing IOException always.
I am trying this through a java application in Windows NT environment. I am using jdk1.3. How can i solve this problem?.
IOException occured at DataLoadFromTxtToOra exeBatchForTWS: CreateProcess: del \\ERSWEB\DTemp\ERS\HEB_428\DATAFILES\ERSWEB\DLCOMMA.txt error=2
Regards,
Babu

you should be able to do that if you have rights on the file, try the following code and substitute the computer/share names:
               File aFile = new File("\\\\COMPUTER\\share\\filename.ext");
               System.out.println("Read: " + aFile.canRead());
               System.out.println("Write: " + aFile.canWrite());
               System.out.println("Exists: " + aFile.exists());
               System.out.println("File: " + aFile.isFile());
               aFile.delete();Mind the slashes: a single backslash is causing a escape character: \n for example is a (unix) return. A double \\ defeats it and results in a single \ in the filename
If everything returns true I think the file will be deleted. If isFile() returns false you've got the path/filename wrong.

Do I need to have my site uploaded to a remote host for embeded formscentral form to work? I am getting a broken section of header with a warning sign on top corner saying "!Local host." Cheers

Hey there all.
I am wondering if there is something wrong with my embedded form or if it is simply because
I have not uploaded my site to remote host yet? I am only getting a broken part of the header with
no actual form, with a warning "!local host" in top left hand corner. If anyone could enlighten
me on this problem it would be greatly appreciated, it is my first time making forms

Cheers, I noticed some browsers were treating the form differently. I am uploading to a test server tomorrow, hopefully all goes well, thanks for your reply
