If you have a 64 bit Oracle Client installed on your desktop/laptop then you will see this error whenever you attempt to connect with Toad to a database. HTH -- Cheers, Norm. [TeamT] ---

I was thinking it was the 64 vs 32 bit issue as well but stumbled over the information that indicated a successful connection the first time. Here’s a possibility that might explain that anomaly: Upon first connection a different (the 32 bit) client was selected. The 64 bit client is set as the default and has been used since. This would explain why a first connection would work and every connection after that would fail. Roger S. ---

Send the contents of your Support Bundle. It’s available from the Help menu within Toad. SQL Developer doesn’t use OCI to connect so it cannot be compared to Toad in this case.

Error -1 **[Can’t initialize OCI. Error -1](http://www.toadworld.com/products/toad-for-oracle/f/10/t/24603.aspx)** Thread created by cfb73 Today I siwtch on the computer and TOAD seems to upgrade itself when I tried to load it. Once the loading process was complete I had lost all my connections and passwords. So I tried to manually type in the connection details. Each time I get: Can’t initialize OCI. Error -1 Yes I have looked at other threads but have not found anything relevant. I’ve unistalled TOAD and loaded back in without any success. The confusing issue is I can use SQL Developer without any issues. So, to my limited knowledge, the clients are OK. Im not convinced its a PATH issue either since I can run Crystal Reports 2008 (32 bit) without issue and dont want to mess up the configuration. Any thoughts?
