Toad on Mac not connecting, what am I doing wrong?

Toad for Oracle & DevOps Toolkit
1

I have these variables set:

export ORACLE_HOME=/Users/user/oic
export TNS_ADMIN=/Users/user/oic/network/admin

OIC directory is the Oracle Instant Client.

2

The error is "iohandler not specified"

Also it is showing no ORACLE_HOMEs set.

3

Mac version cannot use Oracle client, so the "No Oracle Home" message is not a problem. Toad has client functionality built in.

You might have better luck NOT exporting these values. Toad will tell you where it is looking for your TNSNames.ora file if it can't locate it.

If you still get the message, please send me your connection details (I don't need actual server, user, password names, but I need to know what parameters are being specified). Typically that "IOHANDLER" involves SSH or SSL connections.
