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:

*** MODULE NAME:(e:AR:bes:oracle.apps.xla.accounting.extract) 2015-10-01 06:37:00.659 -- станд.модуль OEBS

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.
