 Issue description

 

when we are trying to hit the database by the tcps port, we are getting the below error in the applications log. <o:p> </o:p>

 

We are using clm 6.0.3 version with bundled liberty profile. For enabling mutual authentication with Application DB and application servers we have imported the certificates properly to both source and destination servers. However when we are testing the connection we are getting below error.

“SSLv2Hello is not a recognized protocol.” <o:p> </o:p>


 The used ojdbc string:-   

 

thin:jts_user/{password}@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=192.168.100.216)(PORT=2484))(CONNECT_DATA=(SERVICE_NAME=vmtestdb)))  <o:p> </o:p>

<o:p> </o:p>

You can try this document.

You need an Oracle subscription to see the actual content. I don't so I don't know whether it helps or not.

 HI Donald. Thanks, however we dont have any account.


Please suggest us if u ever faced any issue like this from your experience.

It's the first time I have seen such error. I believe it's more of an Oracle (JDBC driver) issue so you may need to reach out to Oracle Support anyway.

Oracle team suggested that," you are using the SSLv2 protocol, which isn't supported by Oracle. Switching to a supported protocol such as TLS or SSLv3 should resolve the issue".

Here how to make the liberty profile not to use sslv2 and use other protocol like sslv3 or TLS.
