What's the difference between Toad for Oracle 64 bit and 32 bit? What client do I use? Can I install the 32 bit version on a 64 bit machine?
What are the advantages of upgrading to 64 bit?
With Toad for Oracle 11.6, a 64 bit version is available along with the usual 32 bit version.
Toad for Oracle 32 bit can be installed in either a 32 bit or a 64 bit Windows operating system. But it requires a 32 bit Oracle client.
Toad for Oracle 64 bit can only be installed in a 64 bit Windows operating system. It requires a 64 bit Oracle client.
If working with very large data sets (high memory demands), upgrading to a 64 bit version might be helpful. But in general the 32 bit version should be enough. If there were no preformance issues when working with a previous 32 bit version of Toad, there should no be a need to upgrade to a 64 bit version of Toad.
Note that the 64-bit version of Toad will only recognize a 64-bit Oracle Client, even if there is also a 32-bit Oracle client installed, and vice versa for the 32-bit version of Toad.
Please refer to the release notes for a particular version of Toad for more specific info on operative system support and other system requirements.
If the wrong client is installed, Toad will give a connection error when trying to connect, noting an oci.dll error, or suggesting that no client is installed. In this case, verify the version of the install and the version of the Oracle client being used to connect.
