You can create a private vNet in Exalogic Control as follows: 1. The Create Private vNet wizard is displayed, as shown in Figure Figure Create Private vNet Wizard. In the Name field, enter a name for the private vNet. For example, vnet1. Note that the Name field accepts a-z, A-Z, , and characters only. Use the slide bar to set the value. The values entered are rounded up to the next value of 2, 6, 14, 30, 62, , , , , , , and The slider on this screen gives a set of limited values only.
If you enter a value not on the list, the summary displays the next highest number in the list. A private vNet uses n high order bits of the IP address range. The highest and lowest values are reserved. Therefore, 6 IP addresses are available to the private vNet. Review the summary, and click Finish to create the private vNet. After a private vNet is created, you can click the Networks tab on the top navigation bar to verify that vnet1 is listed in the Private vNets section. The Create Distribution Group wizard is displayed, as shown in Figure In the Name field, enter a name for the Distribution Group.
For example, Dept1-distgrp1. Note that the Name field accepts a-z, A-Z, , and - characters only. The size of the distribution group is limited by the actual number of Oracle VM Servers available in the server pools of the vDC. You cannot specify a distribution group for a set of vServers after vServer creation. For information about associating a vServer with a distribution group while creating the vServer, see step 17 in Section 9. To create a volume, complete the following steps: 1. The Create Volume wizard is displayed, as shown in Figure Select the Shared option if you wish to attach the volume to multiple vServers in the account.
If you do not select the Shared option, a volume is created for one vServer to use. Use shared volumes, with caution. The Volume Summary screen is displayed. Review the summary, and click Finish to create the volume in your account. Repeat this procedure to create additional volumes Volume2, Volume3, and. After creating a volume, you must partition the volume using fdisk and create a file system using mkfs on the first vServer to which the volume is attached. For information about attaching a volume to a vServer, see Section 9.
Click Import Volume on the Actions pane under Operate on the right. The Import Volume screen is displayed, as shown in Figure Optional: Select the Shared option, which enables a volume to be used by multiple vServers in the account. Creating, cloning, deleting, or modifying vServers by using Oracle VM Manager will result in unsupported configurations. So before proceeding, checkwith your Exalogic Systems Administratorwhether both the gateway switches are running. The Create vServer wizard is displayed, as shown in Figure In the vServer Name field, enter a name for the vServer to be created.
For example, vserver1. The name of a vServer need not be unique. In the Number of vServers field, enter the number of vServers to be created. For example, 1. If you want to enable high availability for the vServer, leave the High Availability Support check box selected; otherwise, deselect it. For more information about how vServer high availability works, see Section 9. The vServer Type Selection screen is displayed, as shown in Figure Figure vServer Type Selection.
The Attach Volumes screen is displayed.

The networks to which you want to associate the vServer must be assigned to the account and IP addresses must be provisioned as described in Section 9. If you associate the vServer with two or more EoIB networks, then, for enabling access to the vServer from outside the machine through all the EoIB interfaces, you must configure advanced routing on the vServer, by using for example iproute2 or dynamic routing.
If you chose to create multiple vServers by specifying the number of vServers, the IP address assignment is skipped. All IP addresses are allocated automatically. Select an IP address allocation method: static IP, or automatic. If you select static.
If you select automatic, you do not need to enter an IP address; it is selected from IP addresses available for the network. If you select the static IP address option, ensure that you have allocated IP addresses for the network. For more information, see Section After assigning an IP address, click Next. The Distribution Group Selection screen is displayed. If necessary, select one of the available distribution groups in which the new. Note that you cannot assign a vServer to a distribution group after creating the vServer.

From the actions pane on the right, click Stop vServer. In this context, HA is the ability to. This feature is available starting from release 2. Currently, high availability for Exalogic Control VMs is not supported. You must ensure that there are sufficient CPU and memory resources on compute nodes in the vDC for a successful migration of the vServers affected by an unexpected outage.
If none of the compute nodes has sufficient resources, the failed vServer is not migrated. If an HA-enabled vServer crashes, the failed vServer is restarted automatically on the same compute node. However, if the compute node on which the vServer was originally running has failed or does not have enough resources, the vServer is started on the next active compute node in the same server pool.
Note that, if there are no active compute nodes in the server pool, the failed vServer is not started. If the compute node on which a failed vServer is restarted already hosts any vServer that belongs to the same distribution group as that of the restarted vServer, an alert is displayed for the account to which the distribution group belongs in the Incidents tab of Exalogic Control.
To resolve this distribution-group violation, the Cloud User should stop the vServer and then start it again as described in Section 9. If such a compute node is not available, the vServer is not started. If the vServers fail, they are automatically restarted on the same compute node, or migrated to a different compute node if the original node is down, as described in Section 9. In addition, in the vServers tab of any account, you can view the HA state of a vServer by clicking the Status icon corresponding to the vServer.

As the CPU oversubscription ratio increases, performance may be affected, but the utilization of CPU resources improves.
The CPU oversubscription ratio that you might want to use is at most At extremely high ratios, the risk of instability of the system increases. The Edit Volume Storage screen is displayed. If required, select more storage resources to allocate to the vDC from the list; otherwise proceed to the next step.
The vCPU quotas of the accounts in the vDC are fully allocated to the vServers created by the cloud users assigned to the accounts. The memory and storage quotas of the accounts in the vDCs are not yet fully allocated to vServers. Cloud Users want to create more vServers, but cannot do so because the vCPU quota is fully allocated. CPU oversubscription has been enabled and the oversubscription ratio is currently at that is, vCPUs 2 x 24 x 30 are available in the vDC. Only of the available vCPUs are being used by vServers.
The Cloud Admin decides that an oversubscription ratio of would suffice for this vDC. For example, when you want to perform maintenance on a compute node.
