Documentation
Definition
This parameter defines the maximum size of Shared Memory in MB used by each workprocess.
Use
The shared memory segment instantiated by the RAL framework is divided in parts. For each work process a part of the shared memory is allocated. The parameter sets a limit of memory size for each work process. If this values is exceeded the use of the shared memory is blocked until the used memory space has been freed by the memory management. Instead of writing the data to the shared memory, the direct store to the database is used.
Dependencies
The number of work processes of an application server must be multiplied by the value of the maximum size of shared memory. This value should not exceed the value of the shared memory available for the application server.
Example
The standard value for the maximum value of shared memory space is 5 MB. The value of the maximum size for each work process should be adjusted, if the number of work processes multiplied with this parameter value exceeds the complete shared memory size available.
