Solaris 10+ Resource Management

Solaris 10 resource mangement is a major step forward over what was available in Solaris 8 and 9. In Solaris 10, we can manage resources at a zone, project or task level. This page focuses mainly on project-level resource management.

Okes has done a remarkable job creating a book that is readable, concise and useful. There are several well-known books which will smother you with statistics and studies. Okes' book is a common sense introduction to root cause analysis that is general enough to be widely applicable, but specific enough to help most front-line people sharpen their troubleshooting process.

The examples are well-chosen and pointed, and the graphs and charts are explicit and well-explained.

If you need to troubleshoot or perform root cause analyses, this is an excellent book to keep on your bookshelf.

Process accounting can be turned on by referencing the /etc/init.d/acct file, either in a command line with start/stop, or by linking to the appropriate rc file:

ln -s /etc/init.d/acct /etc/rc2.d/S22acct

ln -s /etc/init.d/acct /etc/rc0.d/K22acct

The /etc/acct/holidays file may also need to be edited, if different monitoring is desired during holidays.

Kernel memory size can be tracked using the sar -k command. The total of the "alloc" fields is the kernel memory size. If it appears to be growing without bound, you may have a memory leak. It should be noted that not all buckets are tracked by sar -k, so the reported memory size is not as accurate as that reported by crash.
