Determine the SAP ASE Memory Configuration

The total memory allocated during system start-up is the sum of memory required for all the configuration needs of SAP ASE. You can obtain this value from the read-only configuration parameter total logical memory.

This value is calculated by SAP ASE. The configuration parameter max memory must be greater than or equal to total logical memory. max memory indicates the amount of memory you will allow for SAP ASE needs.

During server start-up, by default, SAP ASE allocates memory based on the value of total logical memory. However, if the configuration parameter allocate max shared memory has been set, then the memory allocated will be based on the value of max memory. The configuration parameter allocate max shared memory enables a system administrator to allocate the maximum memory that is allowed to be used by SAP ASE, during server start-up.

The key points for memory configuration are:
