In a typical SSL usage scenario, a server is configured with a certificate containing a public key as well as a matching private key. Connector/J can encrypt all data communicated between the JDBC driver and the server (except for the initial handshake) using SSL. Eventually, once the handshake completes and the data exchange has been done, either both or one of the entities will eventually close down the connection gracefully. Oracle recommends that users and developers disable use of the SSLv3 protocol. The JMeter Proxy is used for recording a script - as such the browser needs to be configured to send all requests to JMeter for it to record it - you typically dont want to exclude things here (if you did , you'd configure the browser to bypass the JMeter proxy for some hosts) This is different from how JMeter/java itself needing a proxy to make its request.
