What's New in Managing System Processes?

Pseudo Kernel Processes

Oracle Solaris includes several processes that are running on the system. These processes perform a specific task, but do not require any administration. Note that there are no reference manual documents (man pages) that describe these processes.

The following table describes each of these processes.

System daemon that flushes pages to the disk
Initial system process that starts and restarts other processes and SMF components
System process that monitors and balances system load due to interrupts
System process that monitors memory cache sizes
System process that controls memory paging to disk
System process that is responsible for OS scheduling and process swapping
System process with one thread per processor that balances and distributes virtual memory related workloads across CPUs for better performance
System process for each ZFS storage pool containing the I/O taskq threads for the associated pool
