2. VDS independent agent system, also known as virtual dedicated server system (VDS), in short, it is based on easyweb2.0 virtual host management platform to add agents / large enterprises to directly manage their domain names, users, site management interface, a low-cost, high reliability, powerful function, easy to use Easy to maintain virtual independent server management system. VDS virtual independent server provides a revolutionary Linux host storage environment for agent service providers and large enterprises. This environment enables you to have the ability to allocate disk space 24 hours like a real professional virtual host service provider. It is the most effective low-cost server operation mode at present
VDS combines the security independent mode of independent server with virtual host leasing with high performance price ratio, so that companies and indivials who are developing and preparing to enter the field of professional virtual host providers can obtain various powerful management tools at the lowest price that are not available in other places, and provide their customers with website setting, leasing and management services independently.

3. VDS can not be switched, even if it can be charged. Htaccess is under Linux system
4. In the example provided in this article, the source server is configured with a control domain and a guest domain (named ldg1) that hosts the Oracle database. The control domain name is
primary, which is also an I / O domain. In addition, the control domain is also used as a service domain to provide virtual device services (virtual disk and virtual network) for the guest domain
as a service domain, the control domain provides the following virtual device services:
a virtual disk service (primary-vds0), which exports physical disks to the guest domain as virtual disks
a virtual console concentrator service (primary-vcc0) provides access to the guest domain virtual console. This service uses the port range 5000 – 5100
to access the virtual console
a virtual switch service (primary vsw0) is associated with the main network interface (nxge0)
software installation and configuration
follow these steps to configure your environment for real-time migration
installing Oracle Solaris
Oracle Solaris is pre installed on the new SPARC server. For these systems, ensure that the corresponding Oracle Solaris
version is installed, and verify that the required patches are applied
to re install Oracle
Solaris on SPARC system, please refer to Oracle
Solaris 10 documentation or Oracle
Solaris 11 documentation. In the example in this article, the operating system is installed on the first internal disk of the server
after installing Oracle Solaris, you can configure and enable the system to use Oracle VM server for SPARC 2.1 software
install Oracle VM
server for SPARC software
Oracle VM server for SPARC software is also pre installed on the new SPARC server. For these systems, ensure that the corresponding Oracle VM
server for SPARC version is installed, and verify that all necessary patches are applied
if you re install Oracle
Solaris on the server, you may have to re install the Oracle VM server for SPARC software. See Oracle
VM download page
the following example shows the operations performed on each physical server. Oracle Solaris and the required patches have been installed on each server
make sure that the system firmware matches the Oracle VM
server for SPARC version you plan to install. Refer to "required software and patches" in Oracle VM
server for SPARC 2.1 Version Description and "upgrading system firmware" in Oracle VM server for SPARC 2.1

configure storage array
Sun storage 2540-m2 storage array is connected to the control domain, which exports two Lun (Lun 0 and Lun 1) to the guest domain as virtual disks
the guest domain uses the first Lun (Lun 0) as the system disk of the operating system and the second Lun (Lun 1) as the disk for storing Oracle database data files
configure control domain
after installing Oracle VM server for SPARC software, reconfigure the current system to become a control domain. Perform the following operations on each physical server:
create a virtual console concentrator (VCC)
service to be used by the virtual network terminal server daemons (vntd) and serve as a concentrator for all logical domain consoles
primary # LDM add VCC port range = 5000-5100 primary-vcc0 primary

primary # LDM add VDS primary-vds0 primary
create a virtual switch service (VSW)

Oracle VM server for SPARC uses SSL to encrypt migration traffic to protect sensitive data from utilization and eliminate the need for additional hardware and private network
when the primary domains on the source and target computers have assigned encryption units, the speed of migration operation increases. The reason for the increase in speed is that SSL operations can be shunted to the encryption unit
note: SPARC T4 CPU
has built-in encryption instructions, so you don't need to assign them to CPU
determine whether there are encryption devices in the control domain
primary # LDM list - O crypto primary
allocates encryption resources for the control domain
primary # LDM set crypto 1 primary
allocates CPU and memory for the control domain
you can rece the overall migration time by adding more CPUs to the primary domain on the source computer. It is best to allocate at least eight CPUs for each primary domain. For example, the following command allocates 8 CPUs and
4 GB of memory for the control domain
primary # LDM start reconf primary
primary # LDM set vcu8 primary
primary # LDM set memory 4G primary
restart the system< After restarting the system, enable Oracle VM server for SPARC and configure a domain for the system: control domain
primary. In the control domain, you can create and configure other domains
ensure that the logical domains manager
(ldmd) and virtual network terminal server (vntd) services are enabled
primary # svcadm enable ldmd
primary # svcadm enable vntd
Add logical domain computer configuration to service processor (SP)
. For example, the following command adds a configuration called initial
primary # LDM add config initial
verify that the configuration can be used
primary? LDM list config
factory default
initial [current]
configure the guest domain
after configuring the control domain, create the guest domain to be used as the Oracle database node. On the physical server that is the source computer, only one guest domain is created. The other physical server will eventually become the target computer<
the guest domain ldg1 is initially created using the following resources:
8 GB of memory
24 CPUs
a virtual network interface (vnet0), which connects to the virtual switch primary-vsw0
a virtual disk, which is displayed as c0d0 in the guest domain and is a Lun in the storage array. Domain ldg1
uses Lun 0 (c2t6d0) of the storage array
another virtual disk, which is displayed as c0d1 in the guest domain and is a Lun in the storage array. Domain ldg1
uses Lun 1 (c2t6d1) of the storage array. This virtual disk is used to store Oracle database files
perform the following steps to create each guest domain:
on the source computer, create the
ldg1 guest domain from the control domain
note: if your server is not a SPARC T4 based system, only the LDM set crypto command is executed< br />primary# ldm create ldg1
primary# ldm set-vcpu 24 ldg1
primary# ldm set-memory 8G ldg1
primary# ldm set-crypto 3 ldg1
primary# ldm add-vnet vnet0 primary-vsw0 ldg1
primary# ldm add-vdsdev /dev/dsk/c2t6d0s2 vol1@primary-vds0
primary# ldm add-vdisk vol1 vol1@primary-vds0 ldg1
primary# ldm add-vdsdev /dev/dsk/ c2t6d1s2 oradata@primary-vds0
primary# ldm add-vdisk oradata oradata@primary-vds0 Ldg1
after creating a domain, use the following command on the source computer to bind and start the guest domain from the control domain
primary # LDM bind ldg1
primary # LDM start ldg1
determine the console port of the domain
primary # LDM LS ldg1
name state flags cons vcpu memory util uptime
ldg1 active - N --- 5000 248g 0.0% 1H 1m
use telnet command to access the console of
ldg1 domain
after starting the guest domain, ensure that the corresponding Oracle Solaris Operating System and patch are installed in the guest domain. You can perform the installation through the network, from a DVD or using a DVD ISO
image. See the Oracle VM server for SPARC 2.1 administration guide
note: Lun
is usually displayed with different names on different servers. The Lun names in the control domain do not need to be the same. However, the control domains on both systems must virtualize the same Lun (Lun 0 and Lun 1) with the same volume name (Vol1 and
oradata)
the example in Listing 2 shows how to configure a domain named ldg1 with eight CPUs, 24 GB of memory, and two Lun in the sun storage
