Don't run in the background. Useful for debugging.
-d backlog
Specify the default delta backlog, in kilobytes. The default is 256 bytes.
-l argument
(“el”) Set the object load behavior, as follows:
-m mount
Specify the mountpath for PPS. The default is /pps/.
-p path
Set the path for backing up the persistent storage. The default is /var/pps.
-t period
Specify the periodicity of the forced persistence, in milliseconds. For example, -t 5000 forces the PPS service to write to persistent storage every five seconds. The default is no forced persistence.
Enable verbose mode. Increase the number of “v”s to increase verbosity.


The pps program manages the Persistent Publish/Subscribe system, which provides a simple method of disseminating information to interested processes.
