Fix Version: DataMapper 1.4 (was: DataMapper 1.3) Resolution: Fixed Assign To: Gilles Bayon Apply patch from Christopher Bissell In SNV > Pre-load stored procedure parameters should use the already-open connection > of the IDalSession > ---------------------------------------------------------------------------------------------- > > Key: IBATISNET-151 > URL: http://issues.apache.org/jira/browse/IBATISNET-151 > Project: iBatis for .NET > Type: Bug > Components: DataMapper > Versions: DataMapper 1.3 > Reporter: Gilles Bayon > Assignee: Gilles Bayon > Fix For: DataMapper 1.4 > > Report by > Chris Bissell > Managing Architect > MySpace.com > The only performance optimization we've made so far is to ensure that the > call to pre-load stored procedure parameters borrows the already-open > connection of the IDalSession above it. We saw that under super-heavy load > the fact that the sproc parameter populator tried to grab its own connection > within the connection of its parent that a semi-deadlock situation would > result, because the parameter populator does all its work in a heavy lock. > Interested in hearing why this was done, because we definitely got a big > boost on app startup post-optimization. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
