GF v2.1 and HADB ...

I am looking for some insight into HADB ...

Configuration:
     - Solaris 10 u8 on 2 SPARC systems
     - GF v.2.1 running in each system within a Local Zone
     - no shared memory area specified
     - Cluster configured with HADB 4.4.3.6

it seems the HA database is working without having a shared memory area
being specified. Any help available regarding the following questions:

     - What is the purpose of the shared memory ?
     - Why is there no error showing up ?
     - What are the ramifications if shared memory is not configured ?
     - What are the ramifications not being able to set the real time
priority for NSUP
        due to be running in a local zone ?
     - Are all of these performance related ? Would it just impact the
availability rate ?

Thanks in advance,

Peter
