Running Heavy Services
The server.conf file is configured so that only one heavy PPM service can be run at any given time. This is enforced by having the values for the HEAVY_QUEUE_MAX_CONCURRENT_CONSUMERS
and HEAVY_QUEUE_CONCURRENT_CONSUMERS
parameters set to 1 by default.
Although restricting heavy services to run one at a time is recommended, these low settings can be too restrictive. If listeners are unavailable and heavy services are scheduled in a certain way, some services may never run.
To run heavy services, we recommend the following:
-
Set a higher value, such as 6, for the
HEAVY_QUEUE_MAX_CONCURRENT_CONSUMERS
andHEAVY_QUEUE_CONCURRENT_CONSUMERS
parameters. -
Do not schedule a time-consuming heavy service to run at more frequent intervals than its expected run time.
-
Schedule no more frequent runs of heavy services than there are heavy consumers available.
