Re: Event 10235

Hi!

This event is meant for detectiong heap corruptions, by doing additional checks when allocating/deallocating memory. (It affects heap manager).

When set on level 2 it does some check of heap structure when freeing it (level 1) + when allocating/deallocating memory in heap, the memory is filled with junk (level 2). I assume it's because, when you have complete junk in your heap (not some leftover from other session) you'll more likely have a crash in case of some mispointing pointer, thus detecting problems earlier.

So, it's for diagnostics, and you should remove it, especially when on decent Oracle version.

Metalink doc is very sparse (barely more than oerr). It mentions that it protects internal memory management structures. What I am needing are reasons why this event would be set. Anyone have experience with this event and what some of the motivations were?
