Performance Issue: Lazy OTO Unnecessarily Triggered When Querying Via Stored Procedure
Last updated on JUNE 23, 2015
Applies to:Oracle TopLink - Version 18.104.22.168.0 to 22.214.171.124.0 [Release Oracle11g to 12c]
Information in this document applies to any platform.
One to one relationships marked as lazy are being triggered unnecessarily when the objects are queried via a stored procedure in a transaction and REFRESH hint (RefreshIdentityMapResult) is set to true.
As a result, additional queries are issued to the database when they are not needed which lead to performance degradation.

No - Toplink 126.96.36.199/ Eclipselink 2.1.2
No - Toplink 188.8.131.52/ Eclipselink 2.1.3
