Subject [jira] Updated: (DERBY-2328) Reduce monitor contention in SinglePool
Date Wed, 14 Feb 2007 12:06:07 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2328?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-2328:
--------------------------------------

    Attachment: unused.diff

LanguageConnectionContext has a method called getLockSpace(int) which creates a compatibility
space, but the method is not used. unused.diff removes the method so that it doesn't complicate
things when the use of compatibility space objects changes. All the tests passed.

> When multiple threads enter the lock manager, there might be contention on SinglePool's
monitor. The contention should be reduced in order to improve scalability.
