To connect to an Informix DB using SSL/TLS you need to add some driver properties in the connection. The properties are not exposed by the driver, so you will need to add them in Connection using the + tool button.
The properties needed are:
- SSL_TRUSTSTORE=<path to keystore>
- SSL_TRUSTSTORE_PASSWORD=<password>
- SSLCONNECTION=true
For more details, see https://www.ibm.com/docs/en/informix-servers/14.10?topic=options-connecting-jdbc-applications-ssl
Note: Leaving out SSLCONNECTION=true may result in IndexOutOfBoundsException in the JDBC driver.
