A dynamic view, which is also called Dynamic Performance View (DPV), belongs to the SYS user schema. Dynamic views are used by the DBA to monitor the internal operating status of Tibero and thus users are required to have DBA authority when viewing most of the dynamic views.

Unlike static views providing structural information of the database, dynamic views provide status information of the database at a specific point in time. As the information of dynamic views is provided by information stored in memory and control files, it provides accurate information of the current status of the database.

As the information written to memory and the control file reflects changes over time, dynamic views are recommended for database monitoring and tuning. The dynamic views can be seen using the tbSQL tool, but are not updatable or deletable as they are managed by system.

This section provides the list of dynamic views of Tibero in alphabetical order and describes the columns which corresponds to each dynamic view in the table.

The following is the list of summarized dynamic views:

  • Columns

    Column NameData TypeDescription
    NAMEVARCHAR(64)

    Name of a PGA statistic

    - Ex memory soft limit: The maximum amount of PGA memory that can be allocated for the entire working thread running for queries. The memory tuner within the RDBMS monitors the PGA memory usage of the entire thread and adjusts the value accordingly to ensure the value does not exceed the maximum limit.

    - Ex memory operation limit: The maximum amount of memory that can be allocated for a single working thread to use memory (Sort, Hash-Join, and so on) during query executions. The memory tuner within the RDBMS adjusts this value properly when distributing the available memory among a number of working threads simultaneously request memory. The sort and hash-join operation references this value to check whether the operation is possible with its allocated memory. And if not possible, it uses a temporary table space and executes the file I/O operation instead.

    - Total ex memory allocated: The total amount of PGA memory currently occupied by the entire working thread of RDBMS.

    - Total ex memory allocated (max): The highest total PGA memory usage it has ever reached after RDBMS boots. In turn, the system keeps the highest value of the 'Total ex memory allocated' item.

    - FIXED pga memory: The fixed amount of memory that the malloc function directly allocates from the system when booted.

    - ALLOCATED pga memory: The amount of memory allocated using the malloc function and managed by the allocator with the RDBMS. This may increase during the operation.

    - USED pga memory (from ALLOCATED): The amount of 'ALLOCATED pga memory' currently occupied by server processes. This value must be either less than or equal to the value set in 'ALLOCATED pga memory'. And this value is equal to the sum of each 'pga_used_mem' item of the processes listed via v$process.

    - Total workarea memory used: The total amount of memory allocated by the server for query processing.

    - Total workarea temporary segment used: The size of the temporary segments used for query processing.
