We have a SQL query that accepts WHERE clause parameters of date range. 1 year, 2 years, all work predictably. When I use a very large date range (i.e. “everything”), the Oracle dedicated server process crashes.
From the trace file:

Searching Google brought up a Russian blog page, that seems to be citing exactly the same issue:

valid value (0 - 0x8000)
The gist of the post seems to indicate that they are using Oracle 12.1.0.2 and had set TEMP_UNDO_ENABLED=TRUE (a new feature in 12c).
This is interesting because we set this parameter true also, in our code.
Google Translate failed to come through with a useful translation, but it could be that they set this parameter FALSE in order to resolve the problem.
Previously, our test failed after ~2 hours. So far, having made the change to the parameter, it is still running after 4 hours. So, we’re optimistic.
