Question about enabling Automatic Shared Memory Management

John Dunn

2007-08-10


Platform is Oracle 10.
 
I thought that  ASMM was enabled by setting sga_target to a non-zero value.
 
But I recently read the notes below, which confused me.
 
Do I really need to set shared_pool_size to a non-zero value? I thought the whole point of ASMM was that oracle calculated shared_pool_size?
 
 
Oracle Automatic Shared Memory Management is enabled by setting:
  • You must use an spfile for the init.ora values

  • sga_target parameter is set to a non-zero value

  • statistics_level parameter set to to TYPICAL (the default) or ALL

  • shared_pool_size must be set to a non-zero value
