RE: Solaris 10 shmmax

Does it really matter if your shared memory is in one chunk or not?  

..No
 

I seem to remember a bit of misinformation that used to float around was that if the SGA was not in a single shared memory chunk, then ISM was disabled. Turns out that isn't true.  

..It is

  I can't think of any reason why it would be important for the SGA to be in one contiguous memory chunk.  

...no reason
