Memory leak from XMLType.transform
Last updated on MARCH 06, 2015
Applies to:Oracle Database - Enterprise Edition - Version 220.127.116.11 to 18.104.22.168 [Release 11.2 to 12.1]
Information in this document applies to any platform.
Memory usage of a session continues to go every time it calls a program that runs XMLType.transform and an INSERT in a loop. Calling DBMS_SESSION.FREE_UNUSED_USER_MEMORY between runs of the program does not release any significant amount of memory. A heapdump shows the "qmxxvm:subheap" heap is growing. Memory used is released only when the session ends or terminates.
