Troubleshooting Intermittent Problems

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:

  1. We have not identified the real cause of the problem.
  2. The problem is being caused by failing or flaky hardware.

Troubleshooting Hard Drive Connectivity

Disk drive connectivity problems on a Solaris 2.x systems can be caused by software, hardware or PROM configuration problems.

Software Problems

New devices may require that the appropriate /dev and /devices files be created. This can be done through use of the drvconfig and disks commands, but it is usually done by performing a boot -r from the ok> prompt.

Sun CD ROM Troubleshooting

Many CD ROM problems are software rather than hardware problems. If your problem is hardware-related, you can look at our Hardware Diagnostics page. Our page on Hard Drive Connectivity may also be useful by analogy.

ZFS Management

ZFS was first publicly released in the 6/2006 distribution of Solaris 10. Previous versions of Solaris 10 did not include ZFS.

IDC Reviews New SPARC T5 and M5 Servers

recent announcement of Oracle T5 and M5 servers.

IDC's conclusion: "Oracle has invested deeply in improving`the performance of the T-series processors it developed following its acquisition of Sun Microsystems in 2010.

Introduction to Solaris Zones


Zone Introduction

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.

Solaris Process Scheduling

In Solaris, highest priorities are scheduled first. Kernel thread scheduling information can be revealed with ps -elcL.

A process can exist in one of the following states: running, sleeping or ready.

DoD customer receives authority to operate SparcSupercluster

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:

FAQ: Is Solaris 11 "approved for use" in the US DoD?

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.

  • Is Oracle XYZ server or operating system on the DISA approved products list?

MYTHThere is a single organization in the Government/DoD that approves products for use.

Solaris Resource Management

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.
