When allocate max shared memory is set to 1, SAP ASE must have the amount of memory available that is specified by max memory.
If the memory is not available, SAP ASE does not start. If this occurs, reduce the memory requirements for SAP ASE by manually changing the value of max memory in the server’s configuration file. You can also change the value of allocate max shared memory to 0 so that not all memory required by max memory is required at start-up.
You may also want to reduce the values for other configuration parameters that require large amounts of memory. Then restart SAP ASE to use the memory specified by the new values. If SAP ASE fails to start because the total of other configuration parameter values is higher than the max memory value, see System Administration Guide: Volume 2 > Configuring Memory for information about configuration parameters that use memory.
