Error when connecting FTP server

[Former Member]

Hi Experts,

We have issue while connecting to FTP server. These error are captured in Log viewer. These error are received while processing file or only during polling the server.

Usually get below 2 errors:

1. java.net.ConnectException: Connection timed out

2. com.sap.aii.adapter.file.ftp.FTPEx: 500 Unexpected reply codeOOPS: child died

Most connections are Passive with Per file Transfer mode and poll interval of 60 to 120 sec and timeout of 300 sec.Domain name is used instead of IP in Server URL. 50+ FTP channel connecting to same server.

Please suggest on below queries:

1. Is the issue caused by overloaded connection or bad timeout.

2. Should the timeout be increased and to what value?

2. Should the poll interval be increased and to what value?

3. Should the domain name replaced by IP?

4. How many concurrent connection allowed at a time. Any limit?

Thanks

Hi Priyanka,

1. Is the issue caused by overloaded connection or bad timeout.

This issue should be generated when you do a huge number of connections. You should let open one connection and not open/close in every request or to increase the poll.

2. Should the timeout be increased and to what value?

I think it is not necessary.

2. Should the poll interval be increased and to what value?

In my opinion you can increase the poll and to use the same connection.

3. Should the domain name replaced by IP?

I think not.

4. How many concurrent connection allowed at a time. Any limit?

I think, the limit is in the FTP server, not in PI.
