Intermittent problems are extremely difficult to troubleshoot. Any reproducible problem can be troubleshot, if for no other reason than that each individual component can be proven to not be the problem through experimentation. Problems that are not reproducible cannot be approached in the same way.
Problems present as intermittent for one of two reasons:
Disk drive connectivity problems on a Solaris 2.x systems can be caused by software, hardware or PROM configuration problems.
New devices may require that the appropriate
/devices files be created. This can be done through use of the
disks commands, but it is usually done by performing a
boot -r from the
ZFS was first publicly released in the 6/2006 distribution of Solaris 10. Previous versions of Solaris 10 did not include ZFS.
Zones are containers to segregate services so that they do not interfere with each other. One zone, the global zone, is the locus for system-wide administrative functions. Non-global zones are not able to interact with each other except through network interfaces. When using management commands that reference PIDs, only processes in the same zone will be visible from any non-global zone.
In Solaris, highest priorities are scheduled first. Kernel thread scheduling information can be revealed with
A process can exist in one of the following states: running, sleeping or ready.
Recently, one of our good U.S. DoD customers purchased a SPARC SuperCluster system and received their "Interim Authority to Operate" on the DoD network. Why is this a big deal? First, allow me provide an overview of the SPARC SuperCluster system.
SPARC SuperCluster is a relatively new engineered system from Oracle consisting of:
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.
