Disable DISM
Dynamic Intimate Shared Memory (DISM) is not supported for use on SPARC
SuperCluster Solaris environments in instances other than the ASM instance. For
more information, see DISM Restrictions.
Note -
Do not disable the use of automatic shared memory management (ASMM) within
the database, which is a very useful and desirable feature to reduce DBA
management of the database.
-
Disable the use of DISM by the database on Solaris in one of two ways;
either unsetting the SGA_MAX_SIZE / MEMORY_MAX_TARGET / MEMORY_TARGET
parameters, or ensure SGA_MAX_SIZE is set to the same value as SGA_TARGET
parameter or equal to the sum of all sga components in the instance.
