MaxDB Memory Allocation

609 Views

Hi,

How does MaxDB gets memory allocated from os. Could any one please clarify.

Suppose i have X GB of physical memory & i allocated Y GB to CACHE_SIZE(Y < X ). When i start the database does it grabs all Y GB from physical memory.

When i do ipcs on linux box i only see Z GB of shared memory used( Z <<< Y). When i do top db kernel is occupying XX GB of memory (XX > Z).

So little bit confused how MaxDB gets memory allocation from OS.

Thanks in advance.
