file adapter stops pulling files from ftp

[Former Member]

hi,

i defined a communication channel in this way:

adapter type: File

Sender

transport protocol: FTP

message protocol: file content conversion

data connction: passive

connect mode: permanently

Quality of service: exacly once.

somtimes the channel stops working - no indication in message monitioring or communication channel monitoring of any error.

the only way to get it to again and start pulling files again from ftp is to set it to inactive, save, activate, set it to active, save,

activate. somtimes this operation needs to be repeated more than once until it starts working again.

the only relevant note i found is: 999791

https://websmp130.sap-ag.de/sap(bD1oZSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=999791

but this note was already implemented on my system.

Does anyone know what could be the problem?

Thanks,

Please refer SAP Note 1083488 which talks about same issue.

Also please shedule the channel. Make sure that channel will be stopped and started atleast once a day.

Set clusterSyncMode = lock parameter if you have cluster environment. Refer SAP note 801926.

Hi,

In communication channel monitoring, is it so happening that channel is working but it is not fetching any data?

If this is the case, that means, your channel must be getting locked.

For this the solution we have implemented is, in advanced tab, we have mentioned the parameter as 'taskTimeout' and

have assigned the value of 300sec to it.

That means, aftr 300 sec, channel will be unlocked (if at all it is locked) and try to fetch the data again.

If this is not the case with you, then pls explain the issue in detail.

Supriya.
