To disable SSLv3 the configuration of the Apache Tomcat server has to be modified by the following procedure:
- The file ${WMCROOT}/tomcat/conf/server.xml has to be modified. When the value of the parameter ‘sslProtocol’ is “SSL” or “SSLv3” then the parameter value has to be changed to “TLS”.
- The Apache Tomcat server has to be restarted. To restart the server the following commands should be executed by the ‘saserver’ user’:

$ sap stop coreweb
$ sap start coreweb

IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. You should verify disabling SSLv3 does not cause any compatibility issues.
