Is there something with mine rights or some other program that runs as security policy … I’m not a local admin but granted all tasks through some program instead (which is allowing me to do “more sensitive tasks”).

What did you do right before this error was generated? I have occasionally seen similar messages after closing all connections and then trying to make another connection that requires a different Oracle Home.

When we switch from one Oracle Home to another, we have to release one Oracle Home’s DLLs before attaching to those of the other, but I have seen OCI DLLs refuse to be released (for reasons unknown to me) and that leads to this error. If you get this message, I would just close Toad and then restart, making the first connection in the new instance of Toad with the desired Oracle Home.

What did you do right before this error was generated?

Always after closing Toad (with or without opened connections)

When we switch from one Oracle Home to another,

I have two homes (11.2.0.3 and 12.1) but all the connections are pointing to just one-11.2.0.3

Hi John,

Today I installed 12.7.0.51 and remove all connections for the user that was using other ORACLE_HOME (12c) but was never connected in mentioned period, so now only 11.2.0.3 is inside Toad …
Do not if this is important but mentioned as a fact.

Now 5 hours working and no crashes …
