Subject [jira] Updated: (DERBY-4152) mailjdbc test database grows very fast with 10.5
Date Thu, 16 Apr 2009 19:10:14 GMT

Kathey Marsden updated DERBY-4152:
----------------------------------

    Attachment: insertMailSummary.txt

Understanding the primary key violations ended up to be an adventure.   I am attaching insertMailSummary.txt
for those who are interested. Thanks to Myrna for helping me with this.  I made the short
term change described in this document to see if there is other growth besides DERBY-691 on
trunk and have been running for a few hours without noticing any significant growth.

I still have no clue as to what's different between 10.5 and 10.4.

> When I ran the mailjdbc test on 10.5.1.0 RC I found that the mailsdb database grew to
16GB after two days.  On 10.4.2.0  on the same machine with the same configuration (no derby.properties)
it grew to only 1.7GB after 7 days.  Both were sane builds.
> This is with the embedded configuration:
> java org.apache.derbyTesting.system.mailjdbc.MailJdbc embedded
