Enabling TLS 1.2 in IBM Java

Edit online

Starting from application update 9.2.13, TLS 1.2 is enabled in IBM Java by default. If you use an earlier application update, or you previously disabled TLS 1.2, enable it back by changing the value of the Dcom.ibm.jsse2.overrideDefaultTLS parameter to true in the jvm.options file.

Procedure

  1. Go to the computer where the License Metric Tool server is installed.
  2. Go to one of the following directories and open the jvm.options file.
    • Windows icon C:\Program Files\ibm\LMT\wlp\usr\servers\server1\
    • Linux icon /opt/ibm/LMT/wlp/usr/servers/server1/
  3. Set the value of the -Dcom.ibm.jsse2.overrideDefaultTLS parameter to true. 
    -Dcom.ibm.jsse2.overrideDefaultTLS=true
  4. Restart the License Metric Tool server.
    1. Stop the server.
    2. Start the server.
