Configuring CPU Core Count

Oracle Database Appliance is delivered with all cores on each server enabled. Follow this procedure to reduce the number of cores, if required.

About CPU Core Modification

When the CPU core count is modified on Oracle Database Appliance bare metal high availability system, the two nodes are restarted sequentially. After a node is restarted, DCS monitors the start of databases on the bare metal system and DB systems. After all databases on the bare metal system on the first node are started, then the second node is restarted. For DB systems, DCS waits for the virtual machines (VMs) infrastructure to become online but does not monitor databases, applications, or other resources running inside the VM before restarting the second node.

Starting with Oracle Database Appliance release 19.33, you can use the --no-wait option with the odacli modify-cpucore command to skip this monitoring step. When this option is specified, DCS proceeds to restart the next node as soon as Oracle Clusterware is operational on the first node.

  1. To reduce the number of cores, run the following command on Node 0 only:

    Set the cores in multiples of 2, for example, 12:

    [root@oak1 opt]# /opt/oracle/dcs/bin/odacli modify-cpucore --cores 12

    When you run the command, the nodes are restarted to apply the changes.

  2. Check if the job completed successfully:

    [root@oak1 opt]# /opt/oracle/dcs/bin/odacli describe-job -i job_ID

  3. Verify that the core count is updated on both nodes:

    [root@oak1 opt]# /opt/oracle/dcs/bin/odacli describe-cpucore

Changing GRUB Password on Oracle Database Appliance

After provisioning your appliance, you can change the Grand Unified Bootloader (GRUB) password.

Changing the GRUB credentials through the Command-Line

You can change the GRUB credentials using ODACLI as follows:

/opt/oracle/dcs/bin/odacli modify-osconfigurations --grub
GRUB username: bootadmin
Enter GRUB password:
Retype GRUB password:

Changing the GRUB credentials through the BUI

  1. Log into the BUI. For multi-user access enabled systems, log in with the user name odaadmin. For non-multi user access enabled systems, log in with the user name oda-admin.

  2. From the Account menu, select GRUB Configuration.

  3. Enter the values in the GRUB User Name, Password and the Confirm Password, fields, and then click Submit.

    A confirmation message is displayed.

Modifying Oracle ASM Listener Port After Deployment

Understand how you can modify Oracle ASM listener port on Oracle Database Appliance after deployment.

Modifying Oracle ASM listener port using ODACLI commands

In earlier Oracle Database Appliance releases, you provisioned your bare metal system with Oracle ASM listener port 1525 as the default and as the Oracle ASM discovery address port from DB systems. Starting with Oracle Database Appliance release 19.24, you can customize Oracle ASM listener port number as a postinstallation task. All DB systems that you provision after changing the Oracle ASM listener port number use the new Oracle ASM port number.

Use the following command to modify the Oracle ASM listener port number:

odacli modify-asmport -p any_unused_port_between_1024_and_65536

For example:

# odacli modify-asmport -p 1528

Note: You can run the odacli modify-asmport command only on deployments where the bare metal system is on Oracle Database Appliance release 19.24 or later and the DB system is on release 19.24 or later and you use the Oracle AI Database 26ai clones available with Oracle Database Appliance release 19.29.

Important: When you run the `odacli

                                     modify-asmport` command in an Oracle Data Guard enabled environment on a standby system where MAX PROTECTION is enabled, Oracle Clusterware is restarted on the standby system. This may impact the downtime of the primary system. Ensure that you take these factors into consideration when you change the Oracle ASM port on either the primary or standby systems, or both.
                                     {: .infoboxcaution}

Managing Power Consumption on Oracle Database Appliance X11

Understand how you can manage power consumption on Oracle Database Appliance X11.

Important: This feature is applicable only for Oracle Database Appliance X11 hardware models.

The power consumption management feature on Oracle Database Appliance enables you to reduce power usage on supported AMD EPYC-based Oracle Database Appliance systems. Power can be managed in two ways:

Note: Host System Management Port (HSMP) support must be enabled in the system BIOS. On recent firmware, this is enabled by default, but on earlier systems you may need to enable it and restart the system. Refer to the Enabling HSMP on Oracle Database Appliance X11 Systems in this chapter.

The following sections describe these power management options.

Managing Power Consumption Mode

Oracle Database Appliance X11 supports power consumption management.

With power saving mode, you can:

The system can exit power saving mode in three ways:

Managing Power Consumption Schedules

You can automate transitions into and out of power saving mode on Oracle Database Appliance by configuring schedules that specify when the system should enter or exit power saving mode.

Creating Schedules

Schedules must include the following information:

When configuring schedules for power saving mode, the time zone is automatically detected and the system time zone is used. You need not specify a time zone when creating schedules.

Schedule Conflict Management

When adding schedules, understand the following:

Automatic Exit From Power Saving Mode

When in power saving mode, Oracle Database Appliance continuously monitors CPU, disk, and network utilization. If sustained activity exceeds predefined workload thresholds for longer than five minutes, the system automatically exits power saving mode. Power saving mode is resumed at the next scheduled window. Activity is characterized by any of the following:

Automatic transition based on workload does not reset the power limit to the platform default. It only affects the power saving mode, manual or scheduled.

Managing CPU Power Limits

CPU power limits allow you to cap the maximum CPU power consumption on Oracle Database Appliance.

Unlike power consumption mode, CPU power limits do not place the system into a dedicated power consumption mode. Instead, they enforce a configured maximum platform power envelope, applied uniformly across all CPU sockets on the node. Use CPU power limits when you want to keep CPU power consumption within a defined limit for operational, energy, or compliance requirements.

With CPU power limits, you can:

The configured power limit must be within supported platform-specific bounds. On supported AMD platforms, supported CPU power limits are set symmetrically across CPU sockets, in increments of 20W, and cannot be set below 50% of the total supported power limit for the platform.

Viewing Power Consumption State

You can view the current power consumption state on Oracle Database Appliance before making configuration changes.

Viewing current power consumption helps you review whether power saving mode is currently active, the schedules that are currently configured, and the CPU power limit that is currently set. Power consumption state can be viewed using ODACLI or BUI. These interfaces also allow you to review schedule information, current power saving mode state, configured CPU power limits, and power state transitions.

Enabling HSMP on Oracle Database Appliance X11 Systems

Understand how you can enable HSMP on Oracle Database Appliance X11 systems.

Note: When patching an existing Oracle Database Appliance X11 system to Oracle Database Appliance release 19.31, the patching process automatically enables HSMP in the BIOS configuration and installs the necessary AMD E-SMI: EPYCTM System management Interface In-band Library RPMs.

If HSMP is not already enabled on your Oracle Database Appliance X11 system , run these steps on each node as the root user: 1. Verify HSMP status:

<pre class="copy"><code># lsmod | grep -i amd_hsmp</code></pre>

If the module is loaded, HSMP is already enabled and you can skip the remaining steps in this procedure.

  1. Export the current BIOS configuration:

    # ubiosconfig export all -f --expert -y -x /tmp/bios-export.xml

    Check the exported file for <HSMP_Support>Disabled</HSMP_Support>.

  2. Modify the BIOS configuration to enable HSMP:

    # sed -i.bak 's|<HSMP_Support>Disabled</HSMP_Support>|<HSMP_Support>Enabled</HSMP_Support>|g' /tmp/bios-export.xml

  3. Import the updated BIOS configuration:

    # ubiosconfig import all -f --expert -y -x /tmp/bios-export.xml

  4. Restart the system:

    # reboot

  5. Verify the HSMP status after the restart:

    # lsmod | grep -i amd_hsmp
# ubiosconfig export all -f --expert -y -x /tmp/bios-export-new.xml
# grep "<HSMP_Support>Enabled</HSMP_Support>" /tmp/bios-export-new.xml

Managing Power Consumption Using ODACLI Commands

Oracle Database Appliance X11 supports power consumption management using ODACLI commands. Note: The ODACLI commands and processes for configuring and managing power saving mode can only be run by users with root privileges or the ODA-ADMINISTRATOR role in multi-user access configurations. Unprivileged users are not permitted to run these operations.

To enable power saving mode on Oracle Database Appliance X11 hardware models:
