Oracle Error when creating indexes

Question

Help!! I'm getting an error on a spatial create. I read the documents here on this error and I've tried every suggestion.
1. Plenty of free space in the tablespace indx
2. Plenty of free space in the temp tablespace
Does anyone have any ideas??
Thanx in Advance..

Hi Frank,
When you specified "sdo_indx_dim" instead of "sdo_indx_dims",
the parser is ignoring the parameter. Since the default
is 2, it still works fine.
Regarding sdo_rtr_override:
Glad that the workaround helped. This is a non-documented parameter
for R-tree that gives a workaround for any possible bugs that
are introduced as part of new features in new releases. Given
the nature of spatial, there could be some data-specific bugs. In 9.2,
there are some new clustering improvements (internal) and guessing
from the error stack the new one is running out of some stack space
internally due to data outliers (does not occur in all datasets though).
The sdo_rtr_override=0 defaults the behavior of the current operation
(create-index or query) to prior releases (like 9.1). This parameter
allows the users to work uninterrupted while things improve in new
releases. The behavior of this parameter should not be used to compare
performance etc. in different versions though and should be used only
as a workaround. (It is not documented due to these implications
and only recommended when needed by spatial).
Spatial will definitely try to improve on the error messages.
Please file a bug with some sample data or send Oracle
the data at the earliest so that this can be fixed properly.
