Configuring paging space

Many of the configuring tasks can be done with SMIT. Paging space and memory allocation is controlled by the PSALLOC environment variable.

Adding and activating paging space
To make paging space available to your system, you must add and activate the paging space.
Improving paging performance
To improve paging performance, use multiple paging spaces and locate them on separate physical volumes whenever possible.
Configuring the PSALLOC environment variable for early allocation mode
The operating system uses the PSALLOC environment variable to determine the mechanism used for memory and paging space allocation.
Changing or removing a paging space
Changing a paging space is easily done with SMIT, but removing a paging space is more risky.
Using the paging space allocation mode programming interface
The programming interface that controls the paging space allocation mode uses the PSALLOC environment variable.
Relocating and reducing hd6 paging space
You might want to reduce or move the default paging space in order to enhance storage system performance by forcing paging and swapping to other disks in the system that are less busy. Reducing or moving the default paging also conserves disk space on hdisk0.
