The Solaris software includes the following system resources enhancements from prior Solaris 9 releases.
This is a new feature in the Solaris 9 12/03 release.
The resource capping daemon rcapd regulates the consumption of physical memory by processes that run in projects that have defined resource caps. Associated utilities provide mechanisms for administering the daemon and reporting related statistics.
For additional information, see Chapter 4, Solaris 9 Resource Manager Topics, in System Administration Guide: Resource Management and Network Services. See also the man pages rcapstat(1), rcapadm(1M), project(4), and rcapd(1M).
This feature is new in the Solaris 9 9/02 release and has been revised in the Solaris 9 4/03 release.
You can now use extended accounting processes in conjunction with the flow accounting module for IPQoS. For information about IPQoS, see the IPQoS Administration Guide.
For information about the extended accounting feature, see “Extended Accounting” in the System Administration Guide: Resource Management and Network Services.
A Perl interface to libexacct is available in the Solaris 9 4/03 release. This interface enables you to create Perl scripts that can read the accounting files which are produced by the exacct framework. You can also create Perl scripts that write exacct files.
The new interface is functionally equivalent to the underlying C API.
You can use the Perl interface to record system resource consumption on a task or process basis. Or, you can record consumption on the basis of selectors provided by the IPQoS flowacct module.
For information about the Perl interface to libexacct, see Chapter 7, Extended Accounting, in System Administration Guide: Resource Management and Network Services.
