Error description
IIB V10.0.0.3 or above and IIB V9.0.0.6 or above show performance degradation for message flows with FileInput nodes configured for SFTP transport.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM Integration Bus V9.0.0.6 or above, V10.0.0.3 or above, and IBM App Connect Enterprise V11 using the FileNodes with SFTP transport. Platforms affected: z/OS, MultiPlatform **************************************************************** PROBLEM DESCRIPTION: IIB V10.0.0.3 or above, IIB V9.0.0.6 or above, and IBM App Connect Enterprise V11 show performance degradation for message flows with FileInput nodes configured for SFTP transport. This is caused by the change in key exchange algorithms used by the Jsch library version shipped with IIB installation.
Problem conclusion
The product now introduced an environment variable ''MQSI_FILENODES_SFTP_USE_JSCH150_OPTIONS', once this environment variable is set the Jsch libraries will proceed with the key exchange algorithm used in the previous versions of Jsch and it avoids the high CPU usage by the File node flows. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.14 v11.0 11.0.0.2 v9.0 9.0.0.11 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
