Scale 1C database

carefully

During 1C database scaling, all information bases associated with the database may be temporarily unavailable.

We recommend to schedule the work during the minimum load of the 1C database and use session locking for information bases.

When you zoom in, you can:

  • reconfigure;
  • change the ruler — Standard to HighFreq and vice versa;
  • change the number of resources in the current fixed or arbitrary configuration — vCPU, RAM, local disk size. The number of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.

The process of changing the database configuration depends on the availability of the replica:

  • no replica — the master node will be stopped while the changes are applied, the database will be temporarily unavailable for reading and writing;
  • there is a replica — the base will be available for reading and writing in the process of applying changes. First the replica configuration will be changed, then the master node will switch to the replica and its configuration will also be changed.

Configuration change time depends on the amount of data in the database.

  1. In the control panel, in the top menu, click Products → 1C Ready Cloud → Database section.

  2. Open the database page.

  3. Click Scale Base.

  4. Select a configuration.

  5. Specify the desired amount of resources. The amount of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.

  6. Optional: configure replication. A database can have only one replica.

    • To disable an existing cue, uncheck the Add Cue checkbox;
    • If the base does not yet have a replica and you want to create one, check the Add replica checkbox.

  7. Click Save.
