Troubleshooting
Problem
After Rational Application Developer (RAD) or Rational Software Architect Designer (RSAD) is updated to include IBM JDK 8.0.7.5 using Installation Manager, RAD or RSAD may fail to connect to a traditional WebSphere Server.
Cause
TLS 1.0 and TLS 1.1 are vulnerable and have been deprecated. They are disabled by default by IBM JDK 8.0.7.5.
Resolving The Problem
If RAD or RSAD fails to connect to WebSphere Application Server after performing one of the following actions:
- IM update of RAD/RSAD JDK to IBM JDK 8.0.7.5
- IM install/update of RAD 9.7.x or RSAD 9.7.x to RAD 9.7.0.5 or RSAD 9.7.1.1
You can workaround the issue by performing the following steps to expand SSL communications to include/allow TLS v1.2 and restore connectivity to WebSphere Application Server:
- Navigate to the <INSTALL_DIRECTORY>/runtimes/base_stub/properties folder.
- Modify the ssl.client.props file and specify "SSL_TLSv2" instead of "SSL_TLS" for the com.ibm.ssl.protocol property as indicated below:
- com.ibm.ssl.protocol=SSL_TLSv2
