Good Afternoon TOAD team,
I only find the subject error, **Can't initialize OCI. Error -1**, in the beta version; it has been annoying me for months, but I'm finally ready to ask for help. This is recreatable if I connect to a schema other than ETADB3 first, then when I attempt to connect to ETADB3 I get the subject error which takes me to [https://support.quest.com/toad-for-oracle/kb/64853](https://support.quest.com/toad-for-oracle/kb/64853) which does not talk about this error, just other errors. If I connect to ETADB3 first: I do not see the error, even after connecting to other databases and then connecting again to ETADB3. The error happens for any user and as quick connect or from the connection dialogue. My TNSnames.ora file is attached. If I use the Oracle 11g client the error does not occur; this is an Oracle 12c client only issue. Most of the databases I use are Oracle 11G.
