Is there a way in
RAC that I can create 2 TEMP tablespaces which can be explicitly assigned to
separate instances of RAC. Or is there a way that to specify the size
of the instance-specific temp segments? If I have a TEMP tablespace
with a size of 10GB, how can i split it between 2 instances with 5GB each. We're
using 9.2.0.2.
Are there any
white papers that talk about how TEMP is managed in RAC?
As I understand
it, if you have a single TEMP tablespace, there will be 2 temp
segments created under the TEMP tablespace specific to each instance and extents
will be allocated from those segments to each instance's session, but Oracle
doesn't allow for TEMP space to be pre-allocated between instances.
Depending on the instance-specific TEMP segment's requirements, it allocates and
deallocates automatically between segments.
