You must remove SSL keys and certificates to switch from an SSL to a TCP configuration. The manual steps taken in setting up self-signed keys and certificates for SSL must be reverted to TCP manually.
Use the ssl_setup_cert_wrapper.sh script with the -C option to clean up configuration files in the ActiveMQ directory. The script is located in the $DSA_DSC_ROOT directory. Script usage is ssl_setup_cert_wrapper.sh [-h] [-C] [-a activemq_dir], where:
Option Description -h Displays help information. -C Cleans up the configuration files in the specified ActiveMQ directory. -a Specifies the directory where ActiveMQ is installed.
At the Directory prompt, type the full path to the ActiveMQ directory: /opt/teradata/tdactivemq/apache-activemq-5.xx.xx
ActiveMQ restarts after certificates are removed.
