Try with oci/thick/Oracle instant client.
To try oci/thick/Oracle instant client:
(To get the version number right - connect then show jdbc and get the client version)
"Driver Version: 188.8.131.52.0" is the setting on the latest sqlcl download.
Set PATH (in windows) LD_LIBRARY_PATH in UNIX/Linux.
Match versions both instant client and java i.e. both need to be 32 bit
or both need to be 64 bit
My test connection was 184.108.40.206 oracle client to local
220.127.116.11 oracle server, this type of connection may be version sensitive.
