APAR status

  • Closed as program error.

Error description

  • If FileInput node is configured with FTP/SFTP transport and a
high value like 3600 is set as Scan Delay, then this value get
ignored and File Node tries to create FTP/SFTP connection in
every second.

Local fix

  • Set a lower value like 1200

Problem summary

  • ****************************************************************
USERS AFFECTED:
All Users of IBM App Connect Enterprise V11 and V12 using the
FileInput node with Remote Transfer option.


Platforms affected:
MultiPlatform

****************************************************************
PROBLEM DESCRIPTION:
If FileInput Node is configured with FTP/SFTP/FTPS  transport
and a high value like 3600 is set as Scan Delay, then this value
gets ignored and File Node tries to create FTP/SFTP/FTPS
connection in every second. This large number of connection
creation can result in high CPU usage by the Integration Server.

Problem conclusion

  • The product now correctly attempts the remote connection
creation only at the interval specified as the scan delay value.
