RFC Sender: Connection refused
Hi experts,
We are running a scenario with a RFC Sender communication channel.
When the RFC is executed this error occurs in the Runtime Workbench:
Transmitting the message using connection HOSTNAME failed, due to: com.sap.aii.af.ra.ms.api.DeliveryException: java.net.ConnectException: Connection refused: connect
Our basis reported that the HOSTNAME value is incorrect, but could not tell where this information is configurated.
Can anybody tell where is this hostname configurated?
Is there any transaction to check the error?
Thanks anyway.
David,
http://SERVER:8002/sap/xi/engine?type=entry is your integration pipeline URL which belongs to your XI box.
In trasaction SXMB_ADM there are two ways through which you can enter the pipeline URL for the corresponding IE of XI system.
1) By creating and RFC destination and referring that in field "Corresponding Integ. Server" and
2) By directlyspecifying the pipeline URL in above mentioned field
in your case the URL is entered using 2nd option that can be edited by an option Edit-> Change Global parameters.
it will allow you to change the server name.
Thanks,
Sunil Singh

RFC sender connect to PI results in ST22 error - CALL_FUNCTION_NOT_FOUND
Hello,
we are doing an RFC connect with a self defined RFC (simply a trigger, a report that calls a FM with a single value) to
PI.
The connectivity is working, sender channel in comm.channel monitoring is in green.
The function module is imported to PI and implemented in the related scenario.
But when we try to start the call to PI this will simply result in an ST22 error on PI with the message
CALL_FUNCTION_NOT_FOUND.
Does anybody here have an idea about that issue?
We are on SAP PI 7.0 SP 15.
Regards
Dirk> Out implementation:
> We have a TCP IP connection in SM59 of the R/3 with host and service entries for the R/3 system and the registered server prg. name that is the same as in the comm.channel (know about case sensivity).
> The prog. is registered in SMGW on the R/3 now.
This looks perfect!
> In the report where we are calling the function module the destination is the PI connection added as a ABAP Type 3 connection in SM59 of the R/3 system.
Suppose you created TCP IP connection with a name R3_TO_XI, then in the report you have to code it as shown below.
CALL FUNCTION 'your RFC FM name here'
IN BACKGROUND TASK
DESTINATION 'R3_TO_XI'
TABLES
COMMIT WORK.

How to send a file without getting Connection Refused??
Hello everyone!
I'm developing a FTP (Client and Server) program as a project and I have 2 main problems:
1. The program can't connect to computers with router (Connection Refused error)
2. If a computer with router connects to me, the program will not transfer the file (Connection Refused error again). but if it does, my friend's internet is suddenly disconnect after one transfer
what should i do?!? : //
everything is working well on one computer, but when i'm trying to work on 2 computers its screwed
***FOR EVERY TRANSFER I OPEN A DIFFERENT SOCKET AND CLOSE IT (AND ALL THE OTHER STREAMS) IN CASE OF EXCEPTION OR COMPLETION
Thanks!!cotton.m wrote:

How does FTP work normally? Well in most cases you are talking to a server that is on the internet. This server has been configured to be behind or on a network where the routers are not blocking requests to connect to FTP ports (among other services). So nothing different other than it is configured correctly.
I do suspect your program may have some bugs as well. For example when you talk about it dropping the connection after one transfer. That doesn't sound too great.when i checked the program...no
in the test...yes
so the server has no blocking ports, but what about a client with a router?..how do the programs pass the client blocking?
when i checked the program with a friend (i have a modem and i was the server) all the data was perfectly transfered (moving among folders, deleting files, creation of folders-->all these actions on the server..sending codes, strings and stuff), but when i tried to transfer a file it did connection refused :S
i can bring a link to the file that do the transfer and if you have patience to read -

Agent Error? IOException in sending Request :: Connection refused: connect
For the past couple of days, I have been running into the "IOException in sending Request :: Connection refused: connect" error. I am running 10.2.01 on Windows 2003R2.
Along with this error, the DB Control shows agent unreachable.
Is there anything that anyone knows that may have caused this issue?
Thank You in advance,
JeffJhep,
Have you changed the timezone settings on the database server? Check emdctl.trc and see what it says. In the meanwhile, (a) stop dbconsole service, (b) execute emctl resetTZ agent and (c) restart dbconsole service.
Kindly should refer to the following Metalink Notes for a possible workaround:
bq. Metalink Note ID: 362888.1 "Startup Agent: EM Agent will not start due to Timezone mismatch (Daylight \\ Savings changes for Australia)" \\ Metalink Note ID: 409121.1 "Startup Agent: Agent Fails to Start due to Incorrect Timezone File Used as \\ Pointed by ORA_TZFILE" \\ Metalink Note ID: 388280.1 "Startup Agent: ORA-20233: Invalid agent name when running \\ mgmt_target.set_agent_tzrgn procedure in repository"
Lastly, see if any of the following post(s) are of any assistance to you:
bq. Oracle 10g EM DB console Host Preferred Credentials for Windows \\ Oracle 10g EM DB console Host Preferred Credentials for Windows \\ New Error -- Since DST 2007 \\ New Error -- Since DST 2007 \\ DST Patching for Grid Control Release 2 \\ Re: DST Patching for Grid Control Release 2

I set up mac mini and when I test the mail server by sending a mail from administrator to administrator I get the error message 'Diagnostic-Code: X-Postfix; connect to 127.0.0.1[127.0.0.1]:10024: Connection refused'. Can any one suggest a solution
Thanks. Where could I possibly look for a firewall rule. I knowingly did not creat any. My system has internet coming to a Modem which then is connected to a wireless router. I have computers connecting to the router through cable as well as wireless. One of these computers has been our mailserver using Mercury and Pegasus and that computer has a static IP address. The Mac Mini also has been assigned a different srtatic IP address. I have only set up user account, none of them an email account as I initially expect them to receive only internal mails. Is it necessary that I must set up an email id for each user while setting up the user account. My server id is server.local. So would the email id for local users be [email protected]?

Cant send emails nskntcmgw05p BigPond Outbound Connection refused. OB113.
i can receive emails ,but cant send them ,get error message
An error occurred sending mail: The mail server sent an incorrect greeting: nschwcmgw08p BigPond Outbound Connection refused. OB113.bigpond suffer rather badly from incompetence and a disconnect between their technical people and the idiots on support.
If it works sometime and not others you can be almost certain that the good people at Bigpond have managed to mess it up again, unfortunately the IQ of their tech support people is so low that a conversation is about impossible, let along an actual useful solution. Last time I wasted time with them they blamed my copy of Microsoft Outlook and regardless of my assurances that it was simply not installed, refused to change their tack, or put me onto someone with a sufficient grasp on reality to at least consider blaming installed software.
My solution, and that of many others, is to simply not use their email accounts for communication with anyone but bogpond. If I had a choice, I would not be their customer at all, but where I live real choice is not something we have. -
I am new to Mac and i managed to install and configure all the services. Now my issue is when i sending mail using the local server to internal, mails are not receiving. Mail queue showing Connection refused error. Please help me

This happens if the RFC connection pool is not instantiated or may be cache failed to auto-refresh....And manual restart of RFC channel resolves it.
Refer page 8 in the RFC troubleshooting guide.

R3 (rfc-sender) - XI - Webservice ( soap-receiver)
Hi,
I am getting below error whenever webservice(target system) is unavailable.
HTTP 404 Not Found
Then RFC got failed in R3, due to this error in XI
R3 (rfc-sender) <-> XI <-> Webservice ( soap-receiver) Synch
User will enter the request data in R3 and waiting for the response, but webservice is down(i.e not available)
Request is reached to XI box and XI is trying to send data when webservice is down( i,e not available), RFC is waiting for the response from XI box.
how we will handle this kind of situation,how should i give response back to RFC( because RFC sent the request and waiting for the response, XI could not send any response back as Webservce is down, Please advice me how should XI inform to the end user r R3 abt webservice.
I am getting this error to my mail box as i have configured ALERTS. i do not want to change existing RFC.
is there any chance to send response to R3 even webservice is down, please can any one suggest.
Thanks,

Edited by: Siva Grandhi on Jun 18, 2008 1:12 PMHi siva,
check this blog on HTTP errors.
/people/krishna.moorthyp/blog/2006/07/23/http-errors-in-xi
May be the URL you have given in SOAP at receiver adapter is wrong.Check that once.
Error: 404 Not Found
Description: The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
Possible Tips:- for HTTP_RESP_STATUS_CODE_NOT_OK 404
u2022 404 is an HTTP response code that indicates that the resource in question couldn't be found. Usually this is due to an incorrect URL, so it is better to cross check all URLs. Check pipeline URL in the SLD in the business system of the Integration Server For this go to SLD->Business System-><yourIntegrtaion Server>->Pipeline URL: It should be like this http://<host>:<port>/sap/xi/engine?type=entry Where host is the host name of the Integration Server and port is the HTTP(8xxx) port. To verify this in Integration Server you can do like this. Go to SXMB_ADM->Integration Engine Configuration->Choose Edit from Menu -> Change Global Configuration Data to switch to change mode. Then select System Landscape - Load Configuration. (This is not required always)
u2022 Check that the port really is the ICM HTTP Port and not the J2EE port i.e SMICM then menu GOTO --> SERVICES and check the port number for HTTP. It should be HTTP port
u2022 If the error is Page cannot be displayed, cannot find server in https configurations Check and correct the SSL configuration for the ABAP and the J2EE side of the system
u2022 If the error is because of integration server when using Proxy communications then check these. i.e SXMB_ADM->Integration Engine Configuration->Corresponding Integration Server enrty should be dest://<Http Integration server-Destination> Where < Http Integration server -Destination > is the RFC destination (SM59) of type HTTP connection (type H) to the Integration Server. In this case, host name, port, and path prefix are saved in the RFC destination.
Thanks,

transformer.transform(streamSource, streamResult);

pw.close();and when i do the receiverConnection.getOutputStream() it throws

thanks in advanced!!!Comment out your call to setDoInput(true). See if that helps. If not, then it is probably a configuration issue on the server you are attempting to send to.
