Description
Factory value
Access mode
DefaultStoreIsMemory
If set to yes, new tables are created as in-memory tables, unless they are created without an explicit STORE clause in the CREATE TABLE statement. If set to no, new tables are stored on disk by default. You can override the factory value by using the STORE clause in the CREATE TABLE statement.
Note System tables are stored on disk, even if this parameter is set to yes.
yes
RW
MultiprocessingLevel
This parameter defines the number of processing units (processors, cores) available in the computer system. Typically, the concurrency of write operations in the database can be improved if the value matches the number of physical processors (cores) in your system.
The factory value is read from the system as the number of logical processing units. The auto-detected value is output to solmsg.out at server startup. With some processor architectures, the number of logical processing units might not be the same as the number of physical cores. In such cases, the optimal value for this parameter typically varies between the number of the physical cores and the number of logical processing units.
Note The value of the MME.RestoreThreads parameter defaults to the value of this parameter, unless you set it to a different value explicitly.
