Learn how to modify an Exadata VM Cluster and tags from Oracle AI Database@AWS console.

  • Exadata VM Cluster

    These are the steps to modify an Exadata VM Cluster.
    1. From the Oracle AI Database@AWS dashboard, select Exadata VM clusters, and then select your Exadata VM Cluster that you want to modify from the Exadata VM clusters list.
    2. Navigate to Virtual machines section, and expand the section to view the details of your Virtual machines.
    3. Select the Virtual machines link form the list, and then select the Actions button. You can perform the Stop, Start and Reboot steps.
      1. To Stop a virtual machine (VM), select the Stop from the Actions list, and then select the Stop DB node.
      2. To Start a virtual machine (VM), select the Start from the Actions list, and then select the Start DB node.
      3. To Reboot a virtual machine (VM), select the Reboot from the Actions list, and then select the Reboot DB node.

    Tags

    These are the steps to modify Tags within your Exadata VM Cluster.
    1. From the Oracle AI Database@AWS dashboard, select Exadata VM clusters.
    2. From the Exadata VM clusters list, select your Exadata VM Cluster where you want to add or modify a tag.
    3. Select the Tags tab and then select the Manage tags button.
    4. From the Manage tags page, you can complete the following substeps:
      1. You can modify your existing Key and Value fields.
      2. Alternatively, you can add a new tag by selecting the Add new tag button, and then enter your Key and Value pair.
        Note

        The Value field is optional.
      3. Once you modify your information, select the Save button.This screenshot shows the last part of managing tags in Exadata VM Cluster.
    Scale an Exadata VM Cluster
    1. From the Oracle AI Database@AWS dashboard, select Exadata VM clusters, and then select your Exadata VM Cluster that you want to scale from the list.
    2. Select the Manage in OCI button.This screenshot shows how to scale an Exadata VM Cluster.
    3. Subsequent steps for scaling an Exadata VM Cluster are performed through the OCI Console.
    1. To change scaling options, in the OCI console for the selected Exadata VM Cluster, select the Scale VM cluster button.
      1. From the Scale VM cluster page, you can scale your resource usage. The VM count shows you the current Exadata VM Cluster count.
      2. In the Resource allocation per VM section, you can modify the following values.
        1. In the OCPU count per VM field, you can enter a value. This value is constrained by your Exadata Infrastructure.
        2. The Requested OCPU count for the VM cluster is a read-only field.
        3. In the Memory per VM field, you can enter a value. This value is constrained by your Exadata Infrastructure.
        4. The Requested memory for the VM cluster (GB) is a read-only field.
      3. In the Local Storage per VM section, you can modify the following values.
        1. The Allocated and Available fields are read-only. These values are constrained by your Exadata Infrastructure.
        2. In the /u02 (GB) field, you can enter a value. The prompt shows you the range of valid values. This value is constrained by your Exadata Infrastructure.
        3. The Total local storage across VM Cluster (GB) is a read-only calculated value.
        4. In the Advanced options section, which is optional and collapsed by default, you can enter values for / (GB (root), /var (GB), /home (GB), /tmp (GB), /u01 (GB), /var/log (GB), and /var/log/audit (GB). These values are constrained by your Exadata Infrastructure and your previous selections.
      4. In the Exadata storage section, you can modify the following values.
        1. In the Specify the usable Exadata storage (TB) field, you can enter a value. The prompt shows you the range of valid values. This value is constrained by your Exadata Infrastructure.
        2. The Usable storage allocation is a read-only calculated field.
      5. Select the Scale button when finished.

    2. To change the I/O resource management, in the OCI console for the selected Exadata VM Cluster, select the Actions button and the Enable IORM item from the menu. From the Enable I/O Resource Management page, you can change the following options.
      Note

      The Enable I/O Resource Management screen allows administrators to control how Exadata VM Cluster storage I/O resources are allocated across multiple databases. This ensures fair resource usage, prevents one database from monopolizing I/O, and aligns system performance with workload priorities. IORM does not set hard limits, but uses relative shares to prioritize databases. If a database is idle, others can use its share.
      1. From the Objective section, you can choose Low Latency, High Throughput, Auto, or Balanced based on your requirements. To learn more about these options, select the information icon beside the value.
      2. In the Resource Plan Default Directive section, set the Share value. This value specifies the number of shares to assign to each database by default.
      3. The Percentage and Flash Cache Limit are read-only calculated fields.
      4. The Resource Plan Directives (Optional) section, allows you to add directives for individual databases to allocate a greater or lesser share of I/O resources. By default, there are no directives. Select the + Additional Directive button to add one or more.
      5. If a directive is added, the Database field allows you to select an available database. The Share field allows you to increase or decrease that database's resources. The Percentage field is calculated based on your input. The Flash Cache Limit allows you to cap this value, if available for your database.
      6. Select the Enable button to continue.
      This screenshot shows how to change the I/O resource.
    3. To add a tag to your Exadata VM Cluster, in the OCI console for the selectedExadata VM Cluster, select the Actions button and the Add Tags item from the menu. From the Add Tags page, you can change following.
      1. The Namespace dropdown is a single value None (free-form tag).
      2. The Key and Value fields can be used needed.
      3. For more information on what you can do with tags, see Overview of Tagging.
      4. If you want to enter another tag, select the Add tag button.
      5. When you have added the tag(s) you want, select the Add button.
      This screenshot shows how to add tags.
