Preassign vs. Not Preassigned Oracle Libraries

[deleted_user]

I have hit a real puzzler...

Why does my pre-assigned Oracle library work fine BUT when I turn off just the pre-assigned option in SMC, it fails in EG 4.1? This is 9.1.3 SP4 with the library assigned by MLE with no table metadata required.

Here is the message on the failure:

"The library could not be assigned by the SAS server.

Hello Stephen,

You might try a straight libname statement to see if the META engine is working at all in this case:

libname ora META library="Oracle library in metadata";

With pre-assigned in place, the SAS workspace might be assigning the library without using the META engine, instead using the native Oracle engine.
