You manage some system settings by using the App Controller command-line console. You can use the command-line console from the Console tab in either XenCenter or in vSphere. If you enable Secure Shell (SSH) access, you can also open any command prompt, such as PuTTY, and log on to App Controller. The following sections appear in the App Controller command-line console:
With Express Setup, you can configure the basic network settings to enable App Controller to work within your network. These settings include:
For more information about using these settings, see Setting the App Controller IP Address for the First Time.
You can install multiple instances of the App Controller virtual machine (VM) to create a cluster. One App Controller VM acts as the cluster head. All other App Controller VMs in the cluster are called service nodes. Each service node has a local database that is used by the service node only. Updating user information from the service node to the cluster head requires writing to the database. A service node connects to the database on the cluster head by using a secure channel.
Citrix recommends deploying two App Controller VMs in a high availability pair. Each VM is a cluster head. If one VM fails, the secondary VM can act as the cluster head. Citrix also recommends using the gateway proxy to establish a secure connection between the service node and the cluster head.
When you create the cluster head, you enter a shared key for the cluster. When you join additional VMs to the cluster, you enter the shared key. For more information about clustering, see Creating a Cluster.
With high availability, you configure the settings for the primary and secondary App Controller VMs. These settings include:
For more information about configuring high availability, see Configuring High Availability.
With the System Menu, you can configure or view basic system settings that include:
With Troubleshooting, you can access three tools that help you view network settings, view logs, and create a support bundle that you can send to technical support. In Network Utilities, you can do the following:
You can configure logs by using the Logging menu. In the menu, you can:
You can also create a support bundle to send to technical support staff for evaluation.
You can view the date and time in App Controller.
The day, date, time, time zone, and year appear.
When you install App Controller, 50 GB of disk space is allocated in XenServer for the App Controller VM. You can use the command-line console to view how much disk space App Controller is using.
The system disk usage statistics appear.
You can use the command-line console to change the default server certificate in App Controller. When you reset the certificate, App Controller removes the passphrase and the new certificate file overwrites the old certificate file. When you reset the default certificate, you must restart App Controller.
The certificate resets.
You can restart or shut down App Controller by using the command-line console.
