Positional Qualifiers

/WORKING_SET

Specifies the working set quota for the Performance Agent process. The minimum value is 1024. The default working set quota is 2048, and working set extent is 20K. You can override the defaults by specifying different values for quota.

Increase the working set quota when the Performance Agent page faults heavily.

Following the node name parameter in the command, it specifies an integer value for that node only.

Following the collection definition name, it specifies the default value for the entire collection definition.

/FREE_SPACE=n

Specifies the minimum amount of disk space required to keep the Performance Agent running. If the number of blocks falls below this value the Performance Agent notifies you in the Performance Agent log file (PSDC$DATABASE:PSDC$LOG) and pauses until sufficient disk space is released. The default value is 2500 and the range is 0-999,999.

Following the node name parameter in the command, it specifies an integer value for that node only.

Following the collection definition name, it specifies the default value for the entire collection definition.

/PATH=device:[directory]

Following the node name parameter in the command, it specifies a string value for the location for the data files for that node only.

Following the collection definition name, it specifies the default value for the location for the data files for the entire collection definition.

Specify a device and directory or a logical name that indicates a disk directory, which contains the daily collection data files.

Example

$ ADVISE COLLECT ADD PRIMETIME/PATH = $DISK1:[PSDC_DATA]-
_$ /SCHEDULE=(WEEKDAYS = 8-17,NOWEEKENDS)-
_$ /INTERVAL = 300/FREE_SPACE = 50000- 
_$ /CLASSES = (SYSTEM_METRICS,IO_METRICS)-
_$ BERT/PATH=BERT$DISK:[BERTS_PSDC_DATA]-
_$ /WORKING_SET=1536/FREE_SPACE=10000,- 
_$ ERNIE/PATH=ERNIE$DISK:[ERNIE_PSDC_DATA]- 
_$ /FREE_SPACE = 25000,BIGBRD

This command creates a collection definition with entries for the following three nodes:
