FAQ: Does ArcSDE support 64-bit Oracle on 64-bit operating systems?

Question

Does ArcSDE support 64-bit Oracle on 64-bit operating systems?

Answer

ArcSDE is built as a 32-bit application on 32-bit operating systems with the exception of Compaq Tru64.
ArcSDE installation on the same machine with 64-bit Oracle is not a supported configuration.

If a 64-bit operating system is being used other than Compaq Tru64, use one of the following configurations:

1) Use a 32-bit version of Oracle ensuring the operating system vendor guarantees 32-bit compatibility with a 64-bit OS.

2) Install ArcSDE on a second machine using Net8 to connect to the 64-bit Oracle instance.

3) Use direct connect configuration to connect to the 64-bit Oracle 8i instance.
