Closed as program error.
Error description
When using the File Nodes to transfer files to or from a remote server using FTPS, it is not possible to specify the SSL/TLS protocol. Instead the protocol is hardcoded to "TLS". On IBM JRE implentations this means TLSv1.0 only. On Oracle JRE implenentations this means any enabled TLS protocol.
Local fix
It is possible to align the IBM JRE to treat this hard coded value as any allowed TLS protocol by setting the java system properties described here: https://www.ibm.com/support/knowledgecenter/en/SSYKE2_7.1.0/com. ibm.java.security.component.71.doc/security-component/jsse2Docs/ matchsslcontext_tls.html#matchsslcontext_tls

Problem conclusion
This APAR changes the default SSL/TLS protocol used by the file nodes to be TLSv1.2 in line with both the JRE defaults. Additionally this APAR adds a new property "sslProtocol" to the FtpServer configurable service definition in v10 and the FtpServer policy in v11 allowing the user to specify the TLS/SSL protocol. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.21 v11.0 11.0.0.9 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 ---------------------------------------------------------------
