NRQ
The Non Reusable Queue (NRQ) sampler monitors the number of available address space vector table slots (RSVNONR) that are available for replacing address space IDs marked as non-reusable.
It produces a warning message when both of the following conditions occur:
- The number of available address space vector table slots (RSVNONR) that are available for replacing address space IDs marked as non-reusable drops below the specified threshold value (limit1).
- The number of slots that are available for starting new address spaces (available queue) drops below the specified threshold value (limit2).
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
int | is the length of the sample period in intervals; the default interval is 30 seconds |
limit1 | is the threshold for slots reserved for replacing slots marked non-reusable The number of slots on the non-reusable replacement queue (value in ASVTANR) must be less than or equal to the specified number for a warning message to be issued. |
limit2 | is the threshold for the available queue (number of additional address spaces that can be started) The number of slots on the available queue (ASVTAAV) must be less than or equal to the specified number for a warning message to be issued. |
Example
To display a warning message for a specified threshold, type
NRQ 2,5,10
This NRQ sampler checks every two intervals to see if there are less than six (limit1 value) slots remaining on the non-reusable replacement queue and less than 11 (limit2 value) slots on the available queue. A warning message is issued if both limit1 and limit2 have been reached. The message is reissued every minute (two intervals), assuming that the default interval value is 30 seconds, unless the number of slots on the available queue exceeds the limit2 value.
Warning message
The following warning message is issued by the NRQ service:
PWSNRQ01 *WARNING* Non-reusable replacement queue length is nnn
