FTP best practice with XI

[Former Member]

What is the best practice in using FTP adapter which is in vendor network ( external) ? If the connection parameter is set as permanent, or file per transfer, whats the major difference in performance and security? The vendor FTP has uname and pwd for each interfaces from SAP system. If I use file per transfer, everytime the data is sent, FTP takes it in a directory using uname and pwd access. Will it affect the performance ?

Thanks

Ricky,

Permanently should be used when the FTP service is stable and will not go down at all. If the FTP server goes down then if your File Adapter is in permanent mode it will error out due to connectivity issues. You will have to manually restart the file adapter for the connectivity to happen again.

Per file transfer is used when a permamanent connection cannot be guaranteed. Evey polling interval the file adapter will connetc to the FTP service, transfer the file and then close the connection.

There will be a slight performance overhead in per file transfer but I dont think this will be significant and should be negligble.

Thanks Bhavesh. Given points. One more question

In per file transfer, is there any way to avoid checking the uname and pwd always so that performance can be increased. And what was the slight performance issue you were talking about in per file transfer

Thanks

Dont think this can be done. If you do not want User Id and password check the FTP server should allow Anonymous Login and then in the File Adapter you can select Anonymous Login.

And what was the slight performance

> issue you were talking about in per file transfer

As the File Adapter will connect to the FTP server every time it polls in the case of the sender file adapter or every time it wants to transfer a file in the case of a receiver file adapter , there will be a slight issue when comapred to permanenet ( dont think we will even be able to see the difference in the runtime ) . But dont think it will be an issue at all.
