Resource management in solaris zones : Capped memory

By admin

Examples of adding VxFS, ZFS, SVM, UFS, lofs, Raw volumes and disk devices to non-global zones. Resource management in solaris zones : CPU shares, capped CPU, Dedicated CPU assignment Resource management in solaris zones : Dynamic Resource pools Resource management in solaris zones : Capped memory Be default when you create a solaris zone, it will take up all the CPU and memory resources from the global zone. There are ways to limit the memory utilized by zones. The resource capping daemon … [Read more...] about Resource management in solaris zones : Capped memory

Resource management in solaris zones : Dynamic Resource pools

By admin

Resource pools in solaris 10/solaris 11 provides a mechanism to assign processor set and scheduling class to non-global zone. The resource pool framework is as shown in the figure below. The dynamic resource pools comes in extremely useful when you have a variable load on zones and you want to dynamically change the resource allocation to these zones. Unlike the capped CPU allocation, dynamic resource pool allocation to zones is online and can be changed any time online. Note : Resource pool … [Read more...] about Resource management in solaris zones : Dynamic Resource pools

How to clone a solaris 11 zone

By admin

In the last post we saw how to install and configure a basic solaris 11 zone. We can use the ZFS clone feature to clone the existing zone to create new ones. This saves us the time to install and create new zone everytime with all the new softwares that are common to all the zones. As seen in the last post we have a zone named zone01 already created on the global zone. First step to clone any zone is to create a profile and store it as a template. Login to the non-global zone and use … [Read more...] about How to clone a solaris 11 zone

How to create a zone in solaris 11

By admin

In oracle solaris 10, zones was introduced which gave us an ability to create isolated environments for applications that can run on a single machine. Solaris 11 has added a lot of new features to the zones technology. Let us get started and see how we can create a zone in solaris 11. In case you are new to solaris zones refer the post how to create zones in solaris 10 to get started. Pre-requisites : 1. A good laptop/desktop with Solaris 11 virtual machine (VMware workstation or … [Read more...] about How to create a zone in solaris 11

Comparing Network configuration : Solaris 10 Vs Solaris 11

By admin

One of the best things I like about solaris 11 over solaris 10 is the huge change in the network stack in solaris 11. Oracle has added loads of new features to the networking stack of solaris 11. We'll be discussing the new features in solaris 11 network stack and also compare it with solaris 10 where ever applicable. Network Configuration Files The use of below network files has been deprecated starting solaris 11 and it is being managed by SMF to have a Persistent network configuration … [Read more...] about Comparing Network configuration : Solaris 10 Vs Solaris 11

How to configure Probe Based IPMP in Solaris 11

By admin

In the last post we have seen how to configure link based IPMP in solaris 11. Let us see how we can configure a probe-based IPMP in solaris 11. Solaris 11 uses 2 methods for probe-based failure detection 1. Using test addreses (default method) 2. Transitive Probing - No test addresses are used To enable transitive probing : # svccfg -s svc:/network/ipmp setprop config/transitive-probing=true # svcadm refresh svc:/network/ipmp:default To disable transitive probing : # svccfg -s … [Read more...] about How to configure Probe Based IPMP in Solaris 11

How to configure link based IPMP in Solaris 11

By admin

Oracle made a tone of changes to its networking stack in Solaris 11. Persistent network configuration is now managed by SMF, and not by editing following files : /etc/defaultdomain /etc/dhcp.* /etc/hostname.* /etc/hostname.ip*.tun* /etc/nodename /etc/nsswitch.conf IPMP conponents : 1. mpathd daemon - This daemon is responsible to detect an interface failure or repair. It uses a configuration file /etc/default/mpathd to determine when to failover the interface. # cat … [Read more...] about How to configure link based IPMP in Solaris 11
