It would be helpful to know if the SPATIAL_VECTOR_ACCELERATION parameter is enabled in db<>fiddle for **Oracle 18c**.

Reason: I'm trying to optimize a spatial query: [Select polygons that intersect points](https://topanswers.xyz). The SPATIAL_VECTOR_ACCELERATION parameter would likely affect the performance of that query.

-----------------



I can't seem to check from a non-dba user [(Oracle Spatial Community link)](https://community.oracle.com/tech/apps-infra/discussion/4500610/check-if-spatial-vector-acceleration-is-enabled-as-a-non-dba):

>     select * from v$parameter;
> 
> ORA-00942: table or view does not exist



>     show parameter SPATIAL_VECTOR_ACCELERATION;
> 
> ORA-00900: invalid SQL statement
