7.4 About CellCLI Object Types

There are several Oracle Exadata System Software object types that can be used with CellCLI object commands.

• ACTIVEREQUEST — An active request provides a client-centric or application-centric view of client I/O requests that are currently being processed by a cell. The active request object can be used only with the LIST command.

• ALERTDEFINITION — An alert definition provides a definition for every alert that can be produced on the cell. Alerts are defined on metrics and other sources of alerts.

• ALERTHISTORY — An alert history provides a list of alerts that have occurred on the cell.

• CELL — Cell refers to the current or local cell. A cell is the server to which disks are attached and on which the CellCLI utility runs.

• CELLDISK — Each cell disk is associated with a logical unit number (LUN). One physical disk is associated with each cell disk.

• CLUSTER — An Oracle Grid Infrastructure (GI) cluster, which may contain various Oracle databases.

• DATABASE — Database refers to an active database instance.

• DIAGPACK — A diagpack represents a compressed file under $LOG_HOME and contains log files and trace files.

• FLASHCACHE — Flash storage allocated to Exadata Smart Flash Cache.

• FLASHCACHECONTENT — List of all objects currently cached in Exadata Smart Flash Cache.

• FLASHLOG — The portion of flash storage allocated for storing the Exadata Smart Flash Log.

• GRIDDISK — A grid disk is a logical partition of a cell disk. It is exposed on the Oracle Exadata Storage Server network to the database hosts, where it can be consumed by Oracle ASM as part of a disk group.

• IBPORT — The InfiniBand Network Fabric ports for Oracle Exadata Storage Server. Does not apply to Oracle Exadata X8M systems.

• IORMPLAN — An I/O Resource Management (IORM) interdatabase plan is a set of directives that determines allocation of I/O resources to database clients. There is one plan for the cell.

• IORMPROFILE — IORM interdatabase plans support profiles to ease management, and configuration of interdatabase plans for hundreds of databases. Profiles introduce a way to allocate I/O resources for a database.

• KEY — A key is a unique hexadecimal string that identifies clients for security purposes.

• LUN — Logical unit number (LUN) is the address for an individual physical disk device (a single-disk LUN). LUNs are automatically discovered when the cell is started. They are assigned to the corresponding cell disk when the cell disk is first created or when cell disks are discovered after the system is restarted. LUNs that are not yet assigned to a cell disk have a NULL value for the cellDisk attribute.

• METRICCURRENT — Describes the most recent (most current) metric observation.

• METRICDEFINITION — Describes the configuration of a metric.

• METRICHISTORY — Describes the collection of past (historical) metric observations.

• METRICSTREAM — Describes the set of metrics configured for fine-grained collection and Real-Time Insight.

• OFFLOADGROUP — An object that contains modifiable attributes of offload groups, and can be used to restart, start up, and shut down services.

• OFFLOADPACKAGE — An object that contains attributes describing offload support on the cell, including the installation time.

• PHYSICALDISK — A disk is called a physical disk on the cell. Physical disks can be listed, but they are not managed directly by CellCLI. Physical disks are automatically discovered and assigned to the corresponding cell disk when the cell disk is first created or when cell disks are discovered after the system is restarted.

• PLUGGABLEDATABASE — This object describes tenant databases known to the cell.

• PMEMCACHE — The portion of persistent memory (PMEM) storage allocated for use as a cache.

  Note:

  Oracle Exadata System Software release 23.1.0 introduces Exadata RDMA Memory (XRMEM). XRMEM represents the collection of Exadata software technologies that provide direct access to storage server memory using Remote Direct Memory Access (RDMA), enabling faster response times and lower read latencies. In this release, the persistent memory data accelerator, previously known as PMEM cache, is now called XRMEM cache.

• PMEMLOG — The portion of persistent memory (PMEM) storage allocated for caching redo log data.

• PRIVILEGE — A right or permission assigned to a role.

• QUARANTINE — A quarantine stops faulty SQL statements from performing a Smart Scan. This reduces software crashes, and improves storage availability.

• ROLE — A named group of related privileges.

• SOFTWAREHISTORY — A list of final states for past software updates.

• SOFTWAREUPDATE — An object that contains the software location and time parameters for scheduling software updates

• THRESHOLD — A threshold describes the rules for generating stateful alerts based on a specific metric. The rules include boundary (threshold) values and how long the metric values can violate these boundaries before an alert is generated.

• USER — A person allowed access to the storage servers.

• XRMEMCACHE — Memory allocated for use as the Exadata RDMA Memory Cache (XRMEM cache).
