Selecting from view (by another scheme) doesn't use spatial index

I'm using XE to store spatial data. Data are in my general_scheme. I created restricted_scheme+ just with basic privileges to access the data.

The problem starts when I'm selecting data by restricted_schema+ from general_scheme.view+ - I notised that select operation don't use spatial index of the table and select is too slow (f.g. 30 sec. per one select). When I'm selecting data by restricted_scheme+ from data_scheme.table+, everything goes well.

Is that a bug?
It relates just to spatial index.
I tested these events on Oracle 11g and there was no problem with selecting by restricted_scheme.

Thanks for advices.

    After some investigation we found that in the Oracle Patchset ( there is a fix for this bug:

    5487727 SDO_ANYINTERACT can be slow

    Unfortunately we don't have access to Oracle MetaLink so we can't check details about it.
    We tested another machine and it indeed seems to be a problem on both (Express edition) and (Enterprise Edition). Version 11 (Enterprise Edition Release doesn't have problem.
    Can anybody check what is in Metalink about 5487727 and if there's a workaround?

    Support for the XE edition is provided through the XE forum. Please ask your question there.

    Cheers, APC

    Although we founded that problem in XE, it relates really on both (XE) and (Enterprice) editions.
