Subject [jira] Updated: (DERBY-4245) Sorting a table containing a CLOB fails after upgrade to 10.5
Date Wed, 01 Jul 2009 13:49:47 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4245?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-4245:
-----------------------------------

    Attachment: derby-4245-4a-adjust_sort_buffer_test.diff

Thanks for the tip, Knut.

Patch 4a lowers the sort buffer. Although the lowered sort buffer size makes it possible to
run with even fewer rows, I chose to keep it as high as it is (100 rows) due to the randomness
in the test and because lowering it further didn't make the test runs that much faster.

Committed patch 4a to trunk with revision 790162.
