Because of my work with the US DoD and Defense Information Systems Agency (DISA), I get asked this question all the time from Oracle employees as well as customers.
MYTHThere is a single organization in the Government/DoD that approves products for use.
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.
The purpose of resource pools is to segregate different workloads to eliminate their contention for certain types of resources. Resource pools allow persistent configuration for workload processor set and scheduler assignments.
Pools can operate on the following types of elements:
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.
Authors of books in the "Complete Reference" series have always had a tough row to hoe. They attempt to condense an entire set of product documentation to a single, referenceable volume. And all that has to be done in the time frame allowed by software release schedules.
Kudos to the authors of this particular volume for having pulled together a lucid, reasonably detailed summary of the most important parts of Solaris.
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
/etc/acct/holidays file may also need to be edited, if different monitoring is desired during holidays.
Hardly six months after announcing Siebel 18.104.22.168 benchmark results on Oracle SPARC T4 servers, we have a brand new set of Siebel 22.214.171.124 benchmark results on Oracle SPARC T5 servers. There are no updates to the Siebel benchmark kit in the last couple years - so, we continued to use the Siebel 126.96.36.199 benchmark workload to measure the performance of Siebel Financial Services Call Center and Order Management business transactions on the recently announced SPARC T5 servers.
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
Four types of locking are available on Solaris:
The Service Management Facility was introduced in Solaris 9 as an alternative way to manage services. In Solaris 10, SMF has been made the default way to manage most services. The SMF framework has significant advantages over the legacy SVR4 mechanisms, primarily in terms of service monitoring and integration with the Fault Management Facility.
