Register ST_GEOMETRY shape column with GDB system table? (to get a view to utilize a function-based spatial index)

Bud

I'm troubleshooting the following issue with Esri Canada support (case #03065700): Get map to use ST_GEOMETRY function-based spatial index

Question:

Are there any geodatabase system tables that I could register the db view with? (or register the view's ST_GEOMETRY shape column)

I tried registering the view with the geodatabase. But unsurprisingly, that didn't work. The view still doesn't utilize the function-based spatial index, and so the view is still extremely slow.

Thanks.
