Monitoring and Managing Exadata Storage Servers on Exadata Cloud at Customer

This topic explains how you can use the ExaCLI utility on Exadata Cloud at Customer to perform monitoring and management functions on the Exadata Storage Servers.

ExaCLI is a command-line administration tool that runs on Exadata compute nodes and storage server nodes and enables you to manage other nodes remotely. See Using the ExaCLI Utility.

On Exadata Cloud at Customer, ExaCLI is configured on the compute nodes to support essential Exadata Storage Server monitoring and management functions, which are performed without direct administrative access to the Exadata Storage Servers. The ExaCLI utility is located on each Exadata Cloud at Customer compute node at /usr/local/sbin/exacli. To use the ExaCLI utility you require:

  • The ExaCLI command, which specifies the operation that you want to perform.

    For Exadata Storage Server targets, ExaCLI supports the same command syntax as CellCLI. See CellCLI Command Reference. However, ExaCLI on Exadata Cloud at Customer supports only a specific set of monitoring and management operations. For a full list, see Supported ExaCLI Commands on Exadata Cloud at Customer.

  • The username and password to connect to the Exadata Storage Server.

    On Exadata Cloud at Customer, the preconfigured user is cloud_user_clustername, where clustername is the name of the Oracle Grid Infrastructure cluster that is being used. You can determine the Oracle Grid Infrastructure cluster name by running the following command as the grid user on any cluster node:

    $ crsctl get cluster name

    The password for cloud_user_clustername is initially set to a random value, which you can view by running the following command as the opc user on any cluster node:

    $ /opt/exacloud/get_cs_data.py
  • The network address of the Exadata Storage Server that is the target of the operation.

    You can determine the IP addresses for your Exadata Storage Servers by examining the /etc/oracle/cell/network-config/cellip.ora file on any Exadata Cloud at Customer compute node.
