The ADABAS kernel of a started SERVERDB needs the following system resources: queues, shared memory segments, and semaphores.
The number and size of these system resources, and therefore the minimum main memory space requirements, depend on the SERVERDB configuration (e.g., the number of users).
At least 12 MB main memory should be available. 16 MB are recommended to avoid too many main memory swap activities. Sufficient Windows NT system swap space should be configured depending on the main memory size. Otherwise, it could happen that no swap space is available to the Windows NT system in case of dynamically increasing memory requirements (e.g., when another simultaneous database session is being started), so that the requesting kernel process has to be terminated.
The configuration of the SERVERDB is described by a parameter file. The required system resources are calculated from these parameters. The computed values must be compared with the current system configuration (see CONTROL manual).
