Disable DISM

DISM is not supported for use on SuperCluster M8 and SuperCluster M7 Oracle Solaris environments in instances other than the Oracle ASM instance. For more information, see DISM Restrictions.

Note -  Do not disable the use of ASM 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 Oracle Solaris in one of two ways:
    • 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.

    For example, to set a 64 G SGA:

    alter system set SGA_TARGET=64G scope=spfile;
    alter system set SGA_MAX_SIZE=64G scope=spfile;
    alter system set MEMORY_MAX_TARGET=0 scope=spfile;
    alter system set MEMORY_TARGET=0 scope=spfile;
