RFC type communication channel status is red in RWB

HI!
In The Runtime Workbench in component monitoring for my RFC channel the cluster node log is the following:
Receiver channel 'rfc_out' for party '', service 'Diploma_CLIENT000_ON_NE2'
Error can not instantiate RfcPool caused by:

What kind of gateway confirgurations should I check?Is there any other problem here?
Please help.
thanks

HI!
Satish!
My scenario is HTTP-XI-RFC. Why do you think that this time the gateway is not in use? Can you write down your reasoning.
thanks
Bhavesh!
Thanks for the idea. I had made it before, but nothing happened.
Despite of it, since then I tried to active it more than one. After any activation, the error was differed from the previous one. but some cases, there was no error too. I think my XI server is a bit sick.
And the results of the chanel status in the RWB was:

All Communications Channels go to red status.

Hello Folks,
We are on PI .0 SP 19.
I see a repeated problem in our system. All our communications channels go to red status every two weeks. During this time there is a disruption in our services....
I noticed that many of the service nodes goes to red....
The systems seems to come up only when all service nodes are restarted or the entire Java service is restarted...this seems to happen every 2 weeks...
I am not sure what is causing all our channels to go into error status at once. Would appreciate it someone advices me on how to investigate this problem furter...
Has anyone faced similar problems before??
Regards
Arvind

Mine is only an idea...
However, i don't know so much about java memory space... but for tablespace, you can look this document:

Communication Channel Status Is Shwoing RedLed(Error)

Hi,
I used File Adapter in my communication channels that is FTP ... scenario is working fine.. but in the RWB- Communication Channel Monitoring the Communication cHannel is showing RedLed(ERROR Status)
The FTP server was running on UNIX.. that is Bourne Shell ... If the file is there in the source directory it was processing successfully.. even though the remaing all the time it was throwing the following Error Mesage in the RWB-Communication Channel Monitoring..
Could not process file 'SIMS-10.xml: No such file or directory': com.sap.exception.standard.SAPIllegalArgumentException: The parameter "argument" has the value "ftp://10.25.10.6:21./SIMS-10.xml: No such file or directory", so it contains the character "ftp://10.25.10.6:21./SIMS-10*.xml: No such file or directory" which is not allowed
Please Suggest me.
Regards
Jain

Hi ,
We are polling a particular FTP site for files. If file is found communication channel is showing green led with no error message, but when file is not found it is showing red led with an error message in RWB .
My concern :
1. We applied the same approach in other scenarios also , but never came across this type of situation. In other cases if file is not found, communication channel is not showing red led and error message , so this is a metter of real concern to me.
2. I believe that if communication channel is showing red led then definately alerts will get triggered for any error in adapter engine . correct me if wrong ...?
the only difference i found is the shell on which FTP site is configured...We are getting error in bourne shell but no errors in Korn shell ,,,Our XI box is on HP-UX but FTP site is on Solaris 2.8
Is it a bug In PI 7.0 ....?or Something is missing from FTP site ? or some configuration missing at configuration channel level.
Regards

XI Communication Channel Status sent to email/ccms

Hi,
We need to get an alert via email/sms whenever our XI Communication Channel Status got an errors (RED) or got inactive (YELLOW). Please shed some light on this. Thanks.
Regards,
Raquel

Hi Raquel,
Let me try to clear out some things in this thread . First of all you do your alert configuration which you say you have already done. Thats good . Now you ask that you want only to monitor the communication channels and you want specific guide . Here is the specific guide.
If you have configured alerts you will know that when you create an alert rule you have the option to choose radio button where did the error occur it could be no restriction , integration engine or adapter engine. You need to choose adapter engine.
Now whenever the colour of the lights change to red. You will get your alerts.

Intermittent problems with a RFC receiver communication channel.

Hello.
I want to know how to get the total channel history for a RFC receiver communication channel (in RWB only last 5 calls are available).
We use this communication channel in a java mapping to run a RFC of the abap engine of XI. Sometimes the rfc doesn't work and mapping throws a mapping transformation exception. Then, without a modification, we reprocess the message in SXMB_MONI and it is processed without errors. We think that it could be caused by a huge message volume.
How can I get the maximum number of rfc calls that the rfc communication channel can admit simultaneously. Which parameters have influence in these calls?
Thank you very much.
Alberto.

1. Increase the maximum connections
from help.sap.com
Additional Parameters
Parameter ~~~~ Entry
Maximum Connections ~~ Maximum possible number of initial connections required between adapter and sender system. This value is limited internally to a maximum of 50.

Mail to File Integration(Mail Sender Communication channel status RED)

Hi all,
I am doing Email to File Integration Scenario, XI is reading mails from an particular exchange server mail id & putting it in to a file. now all IR & ID configuration is done.
But in RuntimeW Bench -> Adapter Monitreing The Sender Mail Communication Channel is RED with error occured: exception caught during processing mail message; java.io.IOException: invalid IMAP status response; not finding * STATUS, but 00KC NO The requested item could not be found

We check the Exchange Server login Acess through TELNET ,as suggested from SAP Service marketplace
and login is successfull, with details available of Inbox
but in TENET when we try to execute the IMAP Status command error message comes
" expected space not found" .
Since XI is not able to read the inbox mail, so Sxmb_moni is blank.....
can any body suggest that this issus is related to that IMAP Status..........or some thing else..
our URL is correct.
Regards,
Ashutosh

the URL path was wrong...
it should end with .......exchange/Inbox/
the sender channel was having error RED ,but it was showing green status intially because delay update .....
Regards
Ashutosh

Communication Channel status successful but file Not Delivered.

Hi All
I have a receiver communication channel which is showing status as SUCCESSFUL but the log says The message status was set to NDLV. Due to which am unable to retrigger it even form Message Monitoring
Its set to FTP & is not received at that side.
Kindly put in your inputs on the possible solution for this issue.
Regards
Soumen!!!

I dont think it is held in queue.....you will get an error (the one which you got) and then the message will go into Error state.
When the channels are stopped and it receives a file it raises an error alert and is set to error state. Later when channel is started the file gets processed(You can try doing it.I did). Here it gave the error message but sets the channel to successful. Thats what is botehring me.
Looks like you are scheduling the receiver channel....why?
Had some requirement...
@ Balaji : Its successful

RFC Sender Communication Channel is not Working Properly

Hi All,
I had a Small Problem.
I had configured RFC Sender in Asyn mode as given in Weblog 5398
The Scenario is working fine for 1 time, after the execution the Communication Channel should be made Active again to make it work for the next time.
For every time to Execute the Scenario i had to Activate the RFC CC.
It is some complicated one. So any one please suggest me what can be done to Resolve the issue.
Thanks in Advance.

Regarding Communication Channel Error in Component Monitoring(RWB) in Dev

Hi,
In my XI dev Server when I check Component monitoring....Adapter Engine and CC monitoring are showing errors ( showing red
symbol)......
I think my RFC to File Scenario cannot be executed due to this.......I cant receive any messages in SXMB_MONI.....
Please help me......
Thanks,
Sudheer

Hi...
Still I am not getting any messages in the MONI.....
In communication Channel Monitoring it is showing green.......
In Component Monitoring Integration Engine:XID showing red.....CCMS Status: showing red and Adapter Engine Showing red......
Created RFC destination at ECC(of 'T' type) and gave ECC details....Then gave same details in Communication channel in XI.......
I did not created RFC Destination at XI.......
Should data to be passed to RFC or XI automatically pings the data......
When ABAPer executed RFC Connection its successful...but when he executes Functional module i.e test it is showing 'SYSTEM_FAILURE'.....
Thanks,
Sudheer

Communication channels do not appear in RWB

Dear experts,
I am using PI 7.1, after creating some communication Channels for my scenarios, although they appear in the ABAP system (sxi_cache), they do not appear in the RWB.
And when i choose the menu Cache Status Overview in ID, it shows the error below:
"Unable to determine the name of the central Adapter Engine from the System Landscape Directory at this time. Notifications to the central Adapter Engine are therefore listed using the technical name of the Adapter Engine. This is usually structured as follows: af.<SAP System ID>.<Name of application server>"
Pls show me where i am wrong.
Thanks in advance.
Thien Duong.

Regarding RFC Sender Communication Channel

Hi All,
I am working on RFC sender channel, need some important information.
1). Can i use single RFC Sender Channel in Multiple Sender Agreements.
2). Can i use Program ID in Multiple Sender RFC Channels. I am having one RFC to File interface and another RFC to JDBC interface.
Do i need to create 2 sender channels and 2 RFC destinations with 2 Program Ids????.
Please give me clarifications.
Regards,
Balu

If i will use single sender RFC channel and Single Program ID for my all sender agreements, how that Single RFC channel
will identify the information like
In our sender agreement we configure not only the channel but also the Sender Interface (in your case RFC)......this is the factor which defines what to accept......in broader term we use the same concept of channel re-use in other cases also and the same work fine because of this Sender Interface.
I found Q28 interesting: https://service.sap.com/sap/support/notes/730870
In first read it may sound confusing...but after some more rreads you will know what the answer means in the SAP note.

RFC sender communication channel

Hi,
I am working on RFC->XI->SOAP scenario. In R/3, I maintainted an RFC destination with program id same as RFC sender CC in XI, Gateway and host of XI server. But when i test connection the RFC destination, I am getting the following error.
/CPIC-CALL: ThSAPOCMINIT'Transaction program not registered'
Error details: program 'testid' not registered.
What could be the reason and pls let me know if there are any thing else need to be checked or configured. Any blogs or example links are an additional help.
Thanks
Ricky

1) In sap gateway (smgw) of R/3 sender, what should LU Name and TP Name contain? I am right now only seeing R3 host and gateway service respectively for both the columns. Is this correct?
>>>LU name is R/3 Host name. To get the gateway service , go to SMGW>Menu in there GOTO->Parameters-->Display..
Generally it is sapgwXX where XX means System no.
2) The Gateway host of RFC destination in R/3 sender should be what? Is it the business system name in XI for the sender R/3?
>>>It should be Application Server details of the Application System i.e R/3 system. U can get this from the SAP logon pad and application host name. It is not XI server.
Hope this helps,
regards,
Moorthy

Hello everybody,
does anybody know how to establish the values for the cc-parameters?
For example:
Where do I receive information about:

- the Application Server Service (Gateway)
- the Program ID
etc.
