Resizing Memory for an OCI Cache Cluster

Change the memory allocation for an OCI Cache cluster.

You can change the amount of memory per node in an existing OCI Cache cluster to scale up or down based on application requirements.

If you decrease the memory, ensure that the cluster's current data usage fits within the new memory limit. If the attached configuration uses the reserved-memory-percentage parameter, consider the effective Redis or Valkey memory after you exclude the reserved percentage.

Note

You can only resize one configuration setting at a time, and you need to wait for a resize operation to complete before you can start a new resize operation.
    1. On the Clusters list page, select the cluster that you want to work with. If you need help finding the list page or the cluster, see Listing OCI Cache Clusters.
    2. On the cluster's details page, select Actions, then select Resize memory.
    3. In the Resize memory dialog box, enter a number between the 2 and 500.
    4. Select Resize.

  • Use the oci redis redis-cluster redis-cluster update command and required parameters to resize the memory per node for a cluster:

    oci redis redis-cluster redis-cluster update --redis-cluster-id <cluster_OCID> --node-memory-in-gbs <memory_in_gigabytes> [OPTIONS]
    For information about using the CLI, see Command Line Interface (CLI). For a complete list of flags and options available for CLI commands, see the CLI Command Reference.

  • Run the UpdateRedisCluster operation to resize the memory per node for a cluster.
