Property Description
Spin lock retries The number of times a process tries to
acquire a latch before pausing.
If the process cannot acquire the
resource's latch, it continues the attempt.
This iterative process is called spinning.
By default, this value is set to 0.
If the value of this property is greater than
zero, a spin lock algorithm is used for
shared-memory data structures. When a
process has to lock a shared-memory
structure, the process attempts to acquire
the latch for that structure up to the
specified number of times.
If the process has not acquired the latch in
the specified number of attempts, then the
process pauses, or naps. The length of the
pause increases gradually if the process
repeatedly fails to acquire a latch. After
the allotted nap time, the process wakes
up and attempts to acquire the latch again.
If it fails to acquire the latch, it retries up
to the number of attempts specified.
Storage object cache size The size of the object cache for all
database objects.
TXE commit lock skip limit Sets the maximum SHARE/UPDATE
locks that can skip the queued COMMIT
locks.
Note: Do not edit this property unless
directed to do so by Progress Software
Technical Support.
User MUX latches A value that controls the granularity of
access to large database resources in
shared memory.
Note: Do not edit this property unless
directed to do so by Progress Software
Technical Support.
Minimum heap size The minimum value is 0, and the
maximum value is 65535.
The minimum size for temporary storage.
