If you are upgrading from Adabas System Coordinator for Adabas Options version 7.3, you may see an increase in virtual memory requirements for batch jobs and local mode TP jobs. This is due to a change in the way the user session memory pool size is calculated. The size is based on the estimated number of client sessions as defined in the job parameter record for the job. The reason for this change is to improve performance - a correctly sized memory pool is more efficient than one that has multiple extents. Any over-allocation of virtual memory can be rectified by reducing the value of job parameter Client Session.
Adabas System Coordinator requires approximately 256 bytes per client session. Additional memory per session is required. This varies according to which product options are installed and how they are used. Refer to the product documentation for further information.
