parallel query slaves are each going to allocate private areas in memory.
this system configuration does not have enough memory for what you are attempting to do.

Q1: workarea_size_policy [AUTO | MANUAL]  for the instance, session?
If the workarea_size_policy=AUTO, it doesn't matter what you set the sort_area_size to, as its not being used.

Q2: what are the existing settings for the following parameters:

Q3: if in fact, at least for the session, the workarea_size_policy=MANUAL, if 4 parallel query slaves each threw 512 MB of memory, you'd be well over the process limit. Have you attempted this with smaller values for the sort_area_size, say 64 MB and had it complete?

Q4: is this a 32 bit of 64 bit version of solaris, oracle?
(not that you'd want to run 64 bit with only 2 GB of physical memory - I don't see the point there)

Q5: did you examine v$sgastat at the time to see how the memory in the sga was allocated?

that's a start.


Existing Pointers :-

Sometimes decreasing the size of your sort_area_size will remedy this problem.

Another thought is that if you are using parallel query on this view, perhaps the amount of memory required for the number of slaves handling the query is growing too big.
