The primary data collection process allocates non-paged pool resources depending on the number of processes that the system supports and the number of disk drives. For details on setting the non-paged pool requirements, see the Installation Guide.
The primary data collection process allocates resources in the following amounts as shown in the following table:
|
Bytes |
Allocations |
|---|---|
|
38400 |
(1) |
|
Multiply MAXPROCESSCNT by 480 |
(1) |
|
392 |
As needed on CPD process image queue overflow (2) |
|
Multiply MAXPROCESSCNT by 4 |
(1) per active disk |
|
Multiply maximum configured disks by 184 |
(1) |
|
7680 |
As needed on VMS I/O event buffer overflow (1) |
(1) I/O buffer overruns may occur in heavily I/O-intensive environments. See the appendix “Error Messages and Recovery Procedures” for descriptions of the logicals PSDC$IO_FLUSH_FREQUENCY and PSDC$IO_PACKET_MAX. These logicals control the frequency of overruns and specify the maximum number of non-paged pool allocations due to overruns, respectively.
(2) Process image queue overruns increase as the system image activation rate increases.
