    Setting shmmax - conflicting guidelines in installation document

    pnosko
      I've allocated 2GB to my OEL 5.2 virtual machine.

      First, it says...

      Either 4 GB - 1 byte, or
      half the size of physical
      memory (in bytes),
      whichever is lower.
      Default: 536870912

      But then, it says...

      However, if any of the current values are larger than the minimum value, then specify the larger value.

      The current value is 4294967295 (4GB - 1), more than my physical memory. Half my physical memory would be 1073741824. Where does the DEFAULT fit into this equation-- is it even relevant?

      Whichever is lower vs. specify the larger value-- which is it?
