Relation between Redobuffer and SharedGlobalMemoryWhat is (no replies)

Hi,

I want to understand relation between SharedGlobalMemory and RedoBuffer.
Is it ok to set ,
RedoBuffer=512M
SharedGlobalMemory=128M

Or this will led to some config error or error when running sotring the data in mysql. For eg : redo logs overloaded.

Please suggest,

Thnaks,
Sohan
