Trying to connect to a Oracle database listener that has TCPS enabled for network encryption. On the Toad client (v12.10) when making a new connection, I'm using Direct option, when pressing more button there is 'TCPS' option in protocol drop-down. I'm get following error.
ORA-28759: failure to open file
in the sqlnet.ora of the Oracle client home TNS_ADMIN directory, it has appropriate wallet directory and DB certificate loaded.
SSL_CLIENT_AUTHENTICATION = FALSE
