Thanks Ranga
Re: strange startup problem
The database in question was set as a shared and not a dedicated server. So, in trying to increase the shared pool size in OEM, it would not shut down because it is running on a shared memory service. So I had to change or add to the TNSnames.ora and .bak under that TNSname changing it to a dedicated server and it took in the new memory increase quite alright.
addedd (server = Dedicated) in code below:
EDIS =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = fulham)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = dedicated)
      (SERVICE_NAME = edis)
  )and it was fine
Thanks for the reference.
