Specifies the maximum amount of total physical memory that you can configure Adaptive Server to allocate. max memory must be greater than the total logical memory consumed by the current configuration of Adaptive Server.
There is no performance penalty for configuring Adaptive Server to use the maximum memory available to it on your computer. However, assess the other memory needs on your system, or Adaptive Server may not be able to acquire enough memory to start.
See Chapter 18, “Configuring Memory,” in the System Administration Guide for instructions on how to maximize the amount of max memory for Adaptive Server.
When allocate max shared memory is set to 1, Adaptive Server must have the amount of memory available that is specified by max memory. If the memory is not available, Adaptive Server will not start. If this occurs, reduce the memory requirements for Adaptive Server 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 Adaptive Server to use the memory specified by the new values. If Adaptive Server fails to start because the total of other configuration parameter values is higher than the max memory value, see Chapter 18, “Configuring Memory,” in the System Administration Guide for information about configuration parameters that use memory.
