VMware releases certified Data Management for VMware Tanzu database templates and software updates to Tanzu Network. If you have configured a Tanzu Net Token, the Provider checks for new releases once a day at 12:00 AM GMT. If a new release is available, the Provider downloads the bits and pushes them to the Provider Repo.
If you have deployed Data Management for VMware Tanzu in an air-gapped environment, you obtain the database templates and software updates available in a new release from Tanzu Network or VMware Customer Connect as described in Manually Populating Templates and Software Updates, and manually populate the software in the Provider Repo.
An Agent initiates its own update; this occurs some time after the software is available in the Provider Repo.
The information in this topic is relevant to a Data Management for VMware Tanzu user in the Organization Administrator role.
A new Data Management for VMware Tanzu release may include software updates for the Agent VM.
The Agent VM software is updated automatically by Data Management for VMware Tanzu. The Agent polls the Provider 3 times a day for updates, at 12:00 AM, 8:00 AM, and 4:00 PM GMT. If an update is available, and the update is compatible with the current agent version, the Agent:
If the software update fails, manual intervention on your part is required; you may be required to recover the Agent VM.
A new Data Management for VMware Tanzu release may include updated database templates. A database template is comprised of a set of software packages:
The Service Instance VM polls the Agent every 10 minutes for updates. If an update is available, it must be compatible with the current version of the software components on the Service Instance:
Core Service, Adapter, and OS software updates that do not require a reboot are always automatically applied to a Service Instance VM by Data Management for VMware Tanzu. DMS applies Service Instance updates that require a service or VM restart only during the maintenance window configured for the instance.
DMS applies Engine updates during the maintenance window configured for a Service Instance only when the user turned on Enable Auto Minor Version Upgrade during Service Instance creation. If this property is turned off, you are required to manually update the Engine software using the Data Management for VMware Tanzu API.
If Data Management for VMware Tanzu finds that a requested update is compatible:
The Service Instance initiates the software update. The instance Status changes based on the type of update being applied:
|CONTROL_PLANE_UPDATE_IN_PROGRESS||A control plane software update is in progress.|
|DB_ENGINE_UPDATE_IN_PROGRESS||An Engine software update is in progress.|
|OS_UPDATE_IN_PROGRESS||An operating system software update is in progress.|
If the update is successful, the Service Instance is back ONLINE.
If the update fails, you may be required to restore the Service Instance from the last available snapshot.
If you did not check the Enable Auto Minor Version Upgrade property when you created a Service Instance, the only way to update the Engine software is using the Data Management for VMware Tanzu API.
Before you initiate an on-demand Engine software update on a Service Instance, ensure that the Service Instance has no running Data Management for VMware Tanzu or system-level tasks in progress. DMS will not apply an Engine software update when there are tasks running on the Service Instance.
You must also obtain the instance identifier for the service instance. You can obtain the identifier by invoking the
/provider/databases endpoint of the Data Management for VMware Tanzu API, locating the instance in the output, and then extracting its
You invoke the following Data Management for VMware Tanzu API endpoint to initiate an on-demand Engine update of a Service Instance:
Data Management for VMware Tanzu guarantees compatibility between versions n and n-1 releases of the Agent API. If you do not have access to release deliverables that meet this criteria, you must manually update the Agent using the DMS API.
