The Question is:
Which sysgen parameter controls "Lock Manager Dynamic Memory"?
The Answer is :
The bulk of the lock manager structures have been moved to S2 space.
"...For OpenVMS Version 7.2, the lock manager software has been enhanced
to improve the performance of applications that issue a large number of
lock manager requests and to improve application scaling. These
improvements pertain to single systems and to OpenVMS Cluster systems.
"For OpenVMS Alpha, the changes include a new location for most of the
lock manager data structures. These data structures now reside in S2
space in a structure known as a Pool Zone. The SHOW MEMORY display has
been modified to display attributes of the Pool Zone memory used by the
lock manager. For more information, refer to the OpenVMS DCL Dictionary.
Other than the process-level quotas for the lock activity and other the
limits imposed by the available physical memory, there is no limit on
the amount of memory that is available for the lock manager.
