35.3. Applying a Configuration Preset #

Important

When you apply a configuration preset, the instances can be automatically restarted if it is required for changes to take effect.

To apply a configuration preset to one or more instances:

  1. In the navigation panel, go to SettingsConfiguration presets.

  2. If a configuration preset both increases and decreases configuration parameters, split it into two separate presets: one for increasing values and one for decreasing values.

    Then apply both presets individually.

  3. Click Launch a mass application next to the configuration preset.

  4. In Instances, select the instances to which the configuration preset will be applied.

    The order in which you select the instances is the order in which the configuration preset is applied to them.

    Important

    If you select a configuration preset that increases the values of the configuration parameters, first apply it to standby/follower nodes. Otherwise, first apply the configuration preset to the primary/leader node.

    Applying a configuration preset in the wrong order may cause standby/follower nodes to shut down.

  5. Click Next.

  6. In Confirmation, review the list of instances and configure compatibility check:

    1. Review the list of instances and the order in which the configuration preset is applied to them.

    2. Select whether to verify compatibility between the configuration preset and the instance before applying the preset. If the compatibility check fails, the configuration preset is not applied to the instance.

      The compatibility check does not guarantee that no errors will occur when applying the configuration preset.

      You can select one of the following values:

      • For each instance

      • No check

  7. Click Apply.
