Optimizing Garbage Collection
The value is the average number of pages swapped from disk to memory per
second, calculated over the last five seconds. The default is 2000.
To change the values for this parameter using NetWare Remote Manager, do
the following:
1
Click the Set Parameters link in the navigation frame and then the
Memory Category link on the Set Parameter Categories page.
2
Click the value link for the Average Page In Alert Threshold setting.
3
Enter the new value in the Current Value field and click OK.
When disk thrashing occurs, the complete solution is to add more RAM.
Virtual memory cannot compensate for an overall lack of server memory,
although it can prevent processes from failing and allow a server to continue
to function.
The NetWare server provides a
process that periodically collects alloc memory freed by NLM programs and
returns it to cache.
Garbage collection responds to pressure from the virtual memory system. (For
an explanation of virtual memory, see
virtual memory system is checked every 10 seconds.
If pressure on virtual memory is high, then garbage collection is accelerated.
If pressure on virtual memory is low, then garbage collection happens at the
regularly scheduled garbage collection interval. This interval is controlled by
the Garbage Collection Interval server parameter.
To view or change this interval in the NetWare Remote Manager, in the
navigation frame click the Set Parameters link > Memory > Garbage
Collection Interval value link.
Normally, garbage collection happens in the background. The only indicator
that garbage collection has taken place is an increase in the amount of free
memory displayed in MONITOR after garbage collection has freed memory.
