Error opening communication channel tree

Hi,
i'm trying to open the comm channel tree in PI 7.1. When i click on the icon left to expand the tree i'm getting the error message
while trying to invoke the method com.sap.aii.ib.bom.gen.XiReference.getTypeId() of an object loaded from local variable 'xiReference'
Clicking on ok to acknowledge the error message the icon for the comm channels tree disappears.
I was not able to find an oss note for that. Does anybody has some information on how to solve that?
//Rainer

Thx for the quick reply. Strange that i was looking exactly for the error message mentionend in the note but it wasnt popping up...
As i need Basis team to implement the patch and this issue is blocking our development, is there a quick (maybe dirty) workaround?

LMS 3.2 Internal Error in Communication Channel

Hello,
I am having an issue with the DCR in which I get the error "Internal Error in Communication Channel" after trying to edit the credentials of a device.
It started when I tried to add a device to the DCR, with all credentials, and it wouldn't show up in the DCR. I tried this 3x, but no luck. I was eventually able to do so by using the Bulk Import, and having the single device (with all the credentials) in the .csv file.
Now that the device is in the DCR, I need to edit the User Defined Fields - but when I try to, I get the error mentioned above.
I've seen other threads here that talk about multi-server setups, and FQDNs, but I'm not using any of that. I've also noticed that there is a bug ID for it, CSCtd07131, but it says 'release-pending'.
Am I up the creek until an update comes out? (its not just user defined fields, btw, I'm unable to modify any credentials.)
Thanks

When you restart the ciscoworks processes you should always give a couple of minutes and log on when the cpu starts to come down.
If it continues to error when you add or modify you better open a case with the tac.
The bug you mention is only if you have multiple systems with a master and slave DCR
Cheers,
Michel

Hi,
The error could be because
1) The URL referenced from RWB (Communictaion Channel) is incorrect.
        Try accesing the link directly http://HOST:JAVAPORT/mdt/channelmonitorservlet
If you are able to open the window with out nay error, it means you url referenced from SLD is wrong. Correct your SLD and update the cache.
2) If you are not able to access above URL, it means the java service is not running to accept your request, check in visual admin if any of the services are stopped. Try restarting the same.

Advance selection for source file-Error in communication channel monitoring

Hi all,
Referring to the link below:
/people/mickael.huchet/blog/2006/09/18/xipi-how-to-exclude-files-in-a-sender-file-adapter
I have developed my scenario in the same way.But due to the values <NOTHING>
in Mandatory fields Source Directory and Filename,i am facing problem in Communication Channel Monitoring as it shows an error;even though the end-to-end scenario works successfully.
Plase note that our scenario is not to exclude the particular file but to pick the files serially after a certain delay.
Kindly provide some idea about how can we remove the error from Communication Channel Monitoring.
Thanks & Regards,
Sudhir Tiwari

Sudhir,
In the sender file adapter, you have an option called "Processing Sequence".
By selecting ByName or ByDate you can make files get selected sequentially either ByName ( alphabetically ) or by the creation time stamp of the file.
In the sender file adapter also make the QOS as EOIO and give the QueueName as any value and the files will be processed sequentially.
Regards
Bhavesh

Can you tell me the name of this process that causes this conflict?
Then I could disable the virus scanner for this process!!

Go to SXMB_ADM and click integration engine configuration -> click edit mode configuration -> see the tuning parameter EO_MSG_SIZE_LIMIT set and value of it. If it not set, talk to basis to set the this tuning parmeter and value desired.

Page cannot be displayed error in Communication channel monitoring

Hi,
when i am trying to click on Communication channel monitoring from RWB it shows me the error " Page cannot be displayed".
I am testing this for the for the first time in QA environment.
But in development , CC monitoring works fine in the same Laptop.
I have checked the hosts file and it has the IP address and system name present in it.
i have checked in my collegues laptop and it opens there, but it doesn't open in my laptop.
we are using PI 7.0, windows XP and IE 7.0.
Could anyone help to solve this problem?
Thanks
JJ

I am able to open the communciation channel if i am using the path http://<full qualified host>:<http port>/mdt/channelmonitorservlet
This means that there is a problem in the host file....the changes are not getting reflected.....did you log-ff and then again login?
instead of the FQDN you can also open the page using the IP address of the server.
I am really sorry I am unable to give you points, since the Star icon is not displaying in the browser to award points

Error in communication channel in PI 7.1 Server

PI 7.1gives the error shown below when I check the status of the communication channel in the Run Time Workbench. .
Error: com.sap.engine.interfaces.messaging.api.exception.ConfigException: Some of the IS access information is not available. SLDAccess property may be set to true, but SLD is not available.
This occurs after I restart the system , before the restart everything seems to be working fine . This is a vexing problem which is recurring.
I have tried the sap notes

809420
97860
1031321
1117249
1444430
1506101
That includes
1. creating a BS system for the JAVA AS
2. restarting the rwb/adapter/dir/repository etc components
3. releasing locks
4. delayed start of jco etc .
Can anyone suggest a possible solution . would installaing PI 7.1 EHP1 make the SLD problem go away ?
regards

Error in communication channel " not initialized"

Hi All,
I'm working in FIle to mail scenario. In this scenario whenever i upload a text file to the R/3 application server. that file should be sent (as a attachment with a mail) to any email id. I did all the required configuration in IR. but i'm verymuch confused in ID configuration. I have created both sender and receiver communication channel in the same business system which refers a sender (R/3) System.sender communication channel is working fine. but when i activate the receiver communication channel it shows an error "not initialized".
So kindly let me know,
1. Should i use business system for my receiver end?,If so how do i create it?
2. is receiver agreement, receiver determination, interface mapping necessary? If so, how do i configure it? because i'm not using any recever service since i'm sending mail to my mail box.
note:
It would be very helpful if u refer any link to find out the recever determination and interface determination configuration for this type of scenario.
Thanks & Regards,
hari.

Provide us the XML formed after mapping.
make sure that the msg type name is Mail and the name space name is http://sap.com/xi/XI/Mail/30.
