Hello Stefan,

> => But then why ORA-04031 flood, in the first place? According to the system dump there was plenty of free memory to fulfill the request, at least at some point. The scenario of not being able to find consecutive 40 bytes seems rather unlikely.

>> Sorry I may got your question wrong but I thought you wanna know what kind of action triggers MMAN as you wrote "How does a session makes a decision whether to allocate a chunk from the free memory or to wait on 'SGA: allocation forcing component growth'?". Seems like it was not or there is a bug for finding free space :-)

In fact, it's me who caused this confusion, as I didn't know that a session posts MMAN only after getting ORA-04031.

Best regards,

Nenad
