Error description
Connect ECONNREFUSED 9.30.128.37:27001 when trying to log in to Watson Machine Learning for z/OS User Interface
Local fix
Have a local customized java.security file and make sure the provider list has IBMJCE on the top of the provider sequence. Then set up the environment variable IBM_JAVA_OPTIONS pointing to the local customized java.security file.
Problem summary
**************************************************************** * USERS AFFECTED: * * All IBM Watson Machine Learning for z/OS * * V2.3.0 users * **************************************************************** * PROBLEM DESCRIPTION: * * IBM Waton Machine Learning for z/OS * * User Interface (UI) login failed with * * connect ECONNREFUSED error * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** This problem occurs when IBM Watson Machine Learning for z/OS base is configured and started on a Z LPAR where it has crypto express adapter card enabled and configured. At the same time, the search order of cryptography package providers which exploit hardware cryptograph such as IBMJCECCA is higher than the standard Java Cryptography Extension (JCE) provider in the JDK java.security file.
Problem conclusion
The connect ECONNREFUSED error is fixed in the Watson Machine Learning for z/OS core services component by specifying the supported cryptography package provider to the Java interface. After this PTF is applied, restart Waton Machine Learning for z/OS core services for the fix to take effect.
