Oracle is marketing Oracle’s ZFS(Zeta Byte filesystem) is the next generation filesystem. If you say next generation filesystem,will it be enhanced to support OS virtualization ? Yes.It is.Unlike VXVM, we can delegate the entire zpool to local zones.So that we can manage the entire zpool from the local zone level without logging in to global zone.It includes creating […]

How to assign different type of filesystems from Solaris global zone to local zone ? The filesystem type could be type of vxfs , zfs or ufs. Oracle Solaris offers various way of assigning filesystem to Solaris zones.But we need to find out the best method for adding different type filesystems to local zones. The […]
rcapadm – Solaris Online Resource Capping
As you know, system resources like CPU,MEMORY,SWAP can be limited to Solaris local zones using capping.We do the resource capping by just using “zonecfg” command. But the changes are instantaneous ? No. You need to reboot the local zone in a order to take the settings effect.Here we will see how to make the changes instantaneous. But instantaneous […]
Solaris Zone’s Resource capping – MEMORY-CPU
Solaris Zone’s Resource capping: Resource capping is nothing but Limiting the system resources like CPU,Memory,SWAP to local zone.For an example, if you are running local zones without a resource capping,there may be high possibility that one zone will consume all the global zone resources and it will effect other local zones which are running the same global zone.We […]

Solaris 10 – Local zone wise utilization Report using zonestat
I am sure many of the Solaris administrators will break their head in an order to find Solaris local zones wise resource utilization details on oracle Solaris 10. Because there is no simple inbuilt tool to find these details in Solaris 10 (Apart from prstat -Z). I just come across Jeff Victor’s Blog and found this […]
Solaris memory management – Performance issue
Memory bottlenecks are evidenced by two different things happening on the system — paging and swapping. Paging refers to pages of memory being reclaimed by the page daemon when the system starts to get low on free memory. Swapping is more extreme, and refers to entire processes being swapped out. To determine if you are […]
How to create whole root zone on Solaris 11 ?
In this post we will see how to install zone on Solaris 11.Unlike solaris 10,we can’t install it without configuring repo on Solaris. First we need to create a Solaris 11 repo , then you can install Solaris local zone (i.e there is no sparse root zone in Solaris 11) using below method.From Solaris 11 on-wards,all the local zones by default uses exclusive ip address. In exclusive IP, you […]
How to patch the Solaris global zone with vxfs root local zones
In UNIX system administration, we may need to perform OS patching often.But we can;t give any Guarantee that the server will come-up after the reboot.So prior to OS patching we need to make sure ,you have the valid back-out plan.If your global zone’s root filesystem is ZFS,then you have to choose live upgrade in order to perform OS patching. This post will help you […]
