4.8.3 Setting the MAXACCESSERS, MAXOBJECTS, MAXSERVERS, MAXINTERFACES, and MAXSERVICES Parameters

The MAXACCESSERS, MAXOBJECTS, MAXSERVERS, MAXINTERFACES, and MAXSERVICES parameters increase semaphore and shared memory costs, so you must choose the minimum value that satisfies the needs of the system. You must also allow for the variation in the number of clients accessing the system at the same time. Defaults may be appropriate for a generous allocation of IPC resources. However, it is prudent to set these parameters to the lowest appropriate values for the application.

For multithreaded servers, you must account for the number of threads that each server is configured to run. The MAXACCESSERS parameter sets the maximum number of concurrent accessors of an Oracle Tuxedo system. Accessors include native and remote clients, servers, and administration processes. For more information on setting the MAXACCESSERS parameter, see MAXDISPATCHTHREADS.
