Subject [jira] [Updated] (DERBY-5865) On IBM 1.7 TestDurabilityProperty fails with FAIL -- derby.system.durability=test mode seems to be broken.
Date Fri, 14 Sep 2012 15:59:07 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5865?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Matrigali updated DERBY-5865:
----------------------------------

    Labels: derby_triage10_10  (was: )

triaged for 10.10

I don' think this has happened much.  Since it is very intermittent it is more likely either
a test problem
or maybe a machine issue.  The test times two sets of actions and has an expected range of
performance.
Something external could affect the performance.  I think these tests are now on vmware systems
so 
we have even less control on the external effects.

> > -- In this mode one would expect that inserts with autocommit off and on would be
in the same range as syncs are not happening but the difference here seems to be more than
the approximate estimated range.
> > -- Also comparing the time taken to do the inserts without this property set seems
to be in the same range as with this property set.
> > -- Please note this test times inserts and approximate estimates were considered
to report this observation.
> Test Failed.
