Connect Mode: Permanent

[Former Member]

I created a file adapter with a connection mode of permanent. File/FTP. I would have thought this would have logged on the the source system once and then polled at whatever interval I specified.

The Unix admin is telling me XI is establishing a new connection each time which sounds like what per file transfer would do.

Is my understanding of the option correct. SAP library sheds little light.

Hi,

SAP Help~

<i>Permanently

An existing connection to the FTP server is used permanently.

The connection is reestablished automatically if it is closed by the server.

Per File Transfer

A new connection to the FTP server is established for each file transfer</i>

>>>I think in your case , it is closing automatically for each transfer

Just check this SAP note for Timeout handling -849089

Hi Moorthy,

Saw that in help but it isn't much help

I'm polling every second and based on manual FTP the connection would no time time out in less than a second.

What do you think it means by an 'existing connection'. Is that something established outside of XI?

Hi Mark,

did you check the configuration of the FTP server itself? Maybe the server has some kind of configuration so that it closes the connection after each transfer and thus forces XI to reestablish the connection?

If something like that happens, you should be able to see an entry in the XI logs in Visual Administrator. It should say something like "connection lost" or "connection was closed".

I think , connection is getting lost for each transfer.

As mentioned by other response, check the logs..

Hi Christine,

I'm seeing if one of the admins have access to VA. I don't though.

However in the syslog on the unix system it I can see the XI messages and the last one is a quit.
