You can configure some of the settings directly from the CONFIGURATION > Settings page in the App Volumes Manager admin UI, and others through the environment variables.
Configuration Settings
To view and edit the settings, go to CONFIGURATION > Settings.
| Type | Value | Description |
|---|---|---|
| General Settings | UI Session Timeout | The number of seconds App Volumes Manager remains active after the user logs in. The default value is 30 minutes. Set through the system environment variable SESSION_TIMEOUT. |
| General Settings | Certificate Authority File | Path of the certificate file used by machine managers. Set through the system environment variable SSL_CERT_FILE. |
| Volume Mounting | API Mounting | Enable the user to log in even if a Writable Volume or an AppStack cannot be attached to the user at the time of login. Set through the system environment variable AVM_ALLOW_API_MOUNT (or CV_ALLOW_API_MOUNT). |
| Writable Volumes | Delete Protection | Protect volumes from getting deleted directly from storage. Set through the system environment variable AVM_NO_PROTECT (or CV_NO_PROTECT). |
| Writable Volumes | Force Reboot on Error | If a Writable Volume is assigned to a user, and the volume does not get attached to the user, the user has the option to reboot the machine. Set through the system environment variable AVM_WRITABLE_REBOOT. Note: The AVM_WRITABLE_REBOOT does not apply to Writable Volumes conflicts. Writable Volumes conflicts are handled by the Block user login setting. See Create a Writable Volume (2.x) for information about this setting. |
| Writable Volume Backups | Regular backups | Toggle the slider to activate or deactivate regular backups for Writable Volumes. If enabled, Writable Volumes are backed up regularly based on the recurrent interval. For example, if the recurrent interval is set to 7 days, a Writable Volume will be backed up if 7 days have elapsed since the last back up. Back up is only performed for Writable Volumes that have been used at least once since the last backup. |
| Active Directory | Allow or Disallow | The App Volumes Manager expects Computer and User accounts to be members of a registered Active Directory domain. Computer startups and user logins using local accounts are normally ignored. If non-domain entities are allowed, the Manager will create a record for local entities when they are first seen. That entity can then have application packages or AppStacks assigned to it from the Directory tab. |
| Writable Volume Backups | Storage Location | The location where the volumes are backed up. For example, [xxx]AV-LUN. |
| Writable Volume Backups | Storage Path | Name and path of the folder where the volumes are backed up. For example, cloudvolumes/writable_volumes_backup |
| Advanced Settings | Disable Agent Session Cookie | Toggle the slider to activate or deactivate Agent Session Cookie. App Volumes uses a session cookie to optimize the communication between the App Volumes Manager and App Volumes Agent. If you have Agent session issues, you can use this setting to deactivate the session cookies. |
| Advanced Settings | Disable Volume Cache | Toggle the slider to activate or deactivate volume cache. App Volumes caches AppStack or application objects to improve performance. However, if you experience increased memory usage, consider deactivating volume caching. |
| Advanced Settings | Disable Token AD query | Toggle the slider to activate or deactivate token AD query. App Volumes queries for Active Directory group membership using cached object SIDs. Previous versions of App Volumes performed group membership queries against Active Directory domains directly and recursively. Deactivate token AD query to revert to the previous implementation. |
| Advanced Settings | Enable Volumes (2.x) | Toggle the slider to activate or deactivate the VOLUMES (2.X) tab.
VOLUMES (2.X) tab is for working with AppStacks and Writable Volumes along with App Volumes Agent 2.x. For upgraded deployments, this setting can be deactivated after the AppStacks and Writable Volumes are completely migrated. If you have newly installed App Volumes Manager, for more information about this setting, see Perform App Volumes 2.x Management Tasks. If you have upgraded to the latest version of App Volumes Manager, for more information about this setting, see Configuring visibility and management of App Volumes Manager 2.x UI. |
| Advanced Settings | VMDK Package Attachment Resiliency | If this setting is turned on, any VMDK attachment failures are skipped and the remaining VMDK packages are attached.
If this setting is turned off, no packages are attached during failures.
When the setting is turned on, for package attachment resiliency to occur, ensure that you have the following system requirements:
|
| Advanced Settings | Dynamic File Permissions | Use this checkbox to dynamically control the permissions given to the App Volumes agent machines to access Writable Volumes when App Volumes is configured in the VHD in-guest mode.
