DBA_WORKLOAD_REPLAYS

DBA_WORKLOAD_REPLAYS displays all the workload replays that have been performed in the current database. It also lists replays on which DBMS_WORKLOAD_REPLAY.GET_REPLAY_INFO() has been called. Each row contains information about one workload replay.

Column Datatype NULL Description
ID NUMBER NOT NULL Internal key for the workload replay
NAME VARCHAR2(128) NOT NULL Name of the workload replay
DBID NUMBER NOT NULL ID of the database in which the workload was replayed
DBNAME VARCHAR2(10) NOT NULL Name of the database in which the workload was replayed
DBVERSION VARCHAR2(128) NOT NULL Version of the database in which the workload was replayed
PARALLEL VARCHAR2(3)   Indicates whether the database in which the workload was replayed was an Oracle RAC database (YES) or a single instance database (NO)
DIRECTORY VARCHAR2(128) NOT NULL Name of the directory object for the workload replay
CAPTURE_ID NUMBER   ID of the capture (DBA_WORKLOAD_CAPTURES.ID) that was replayed
STATUS VARCHAR2(40) NOT NULL Current status of the workload replay:

  • PREPARE - Workload prepare has been started and is waiting for clients to join

  • IN PROGRESS - Workload replay is in progress

  • COMPLETED - Workload replay has successfully completed

  • CANCELLED - Workload replay or the workload prepare has been cancelled

  • FAILED - Workload replay was aborted due to errors encountered. See the COMMENTS column for further information.
PREPARE_TIME DATE   Datetime at which the workload prepare started
START_TIME DATE   Datetime when the replay began
END_TIME DATE   Datetime when the replay completed or cancelled; NULL if the replay is still in progress
DURATION_SECS NUMBER   Duration of the workload replay (in seconds)
NUM_CLIENTS NUMBER NOT NULL Number of workload replay client processes that were used in this workload replay
NUM_CLIENTS_DONE NUMBER NOT NULL Number of workload replay client processes that have finished replay
FILTER_SET_NAMEFootref 1 VARCHAR2(1000)   Name of the filter set used for the replay
DEFAULT_ACTION VARCHAR2(30) NOT NULL Reserved for future use
SYNCHRONIZATION VARCHAR2(9)   Indicates whether recorded transaction semantics should be maintained (TRUE) or not (FALSE)

When synchronization is on, the commit order observed during the original workload capture will be preserved. Every action that is replayed will be executed only after all of its dependent commits have been executed. Dependent commits are commits that were issued before the given action in the original workload capture.

CONNECT_TIME_SCALE NUMBER NOT NULL Connection time scaling factor for captured streams during replay. The value is interpreted as a percentage.The default value of 100 means 100 percent.

See Also: DBMS_WORKLOAD_REPLAY.PREPARE_REPLAY() in Oracle Database PL/SQL Packages and Types Reference for a detailed explanation of this replay parameter
THINK_TIME_SCALE NUMBER NOT NULL Think time scaling factor for captured streams during replay. It scales the thinking time elapsed between two successive user calls from the same captured stream. The input is interpreted as a percentage. The default value of 100 means 100 percent.

See Also: DBMS_WORKLOAD_REPLAY.PREPARE_REPLAY() in Oracle Database PL/SQL Packages and Types Reference for a detailed explanation of this replay parameter
THINK_TIME_AUTO_CORRECT VARCHAR2(5)   Indicates whether the think time should be automatically corrected between calls (TRUE) or not (FALSE)

A value of TRUE reduces think time if replay goes slower than capture.

A value of FALSE results in no action.

SCALE_UP_MULTIPLIER NUMBER NOT NULL Before the multiple-capture replay, SCALE_UP_MULTIPLIER is used to scale up the query part of a workload capture. The queries from each captured session are replayed concurrently as many times as the value of SCALE_UP_MULTIPLIER.
USER_CALLS NUMBER   Total number of user calls replayed
DBTIME NUMBER   Accumulated database time for the replay
NETWORK_TIME NUMBER   Accumulated network time for the replay
THINK_TIME NUMBER   Accumulated think time for the replay
PAUSE_TIME NUMBER   Time that the replay spent in the paused state
ELAPSED_TIME_DIFF NUMBER   Reserved for future use
AWR_DBID NUMBER   Database ID of the AWR snapshots that correspond to this workload replay. For replays that were performed in the current database, this value is equal to the current database's DBID. For replays that were performed in other databases, this value will either be NULL or will be populated by DBMS_WORKLOAD_REPLAY.IMPORT_AWR().
AWR_BEGIN_SNAP NUMBER   Begin snapshot ID of the AWR snapshots that correspond to this workload replay
AWR_END_SNAP NUMBER   End snapshot ID of the AWR snapshots that correspond to this workload replay
AWR_EXPORTED VARCHAR2(12)   Indicates whether the AWR snapshots that correspond to this workload replay have been exported using DBMS_WORKLOAD_REPLAY.EXPORT_AWR() (YES) or not (NO), or whether AWR snapshots cannot be exported because the replay is still in progress, has run to completion successfully, or was done in a different database from which it was not exported (NOT POSSIBLE)
ERROR_CODE NUMBER   Error code for this workload replay
ERROR_MESSAGE VARCHAR2(300)   Error message for this workload replay
DIR_PATH VARCHAR2(4000) NOT NULL Full directory path for the replay directory object
REPLAY_DIR_NUMBER NUMBER   A hash value computed based on the values of other columns in this view, such as the NAME, DBID, DBNAME, PREPARE_TIME, START_TIME, and END_TIME columns. It should be fairly unique for any replay. The value is used to create a subdirectory under the replay directory.
SQLSET_OWNERFoot 1  VARCHAR2(128)   User name of the SQL tuning set owner
SQLSET_NAMEFootref 1 VARCHAR2(128)   Name of the SQL tuning set for this workload replay
SCHEDULE_NAMEFoot 2  VARCHAR2(128)   The name of a schedule to be replayed. It defines one or multiple workload captures, and the order to start their replays.

If SCHEDULE_NAME is NULL, the replay is a regular replay introduced since Oracle Database 11g, done with existing APIs from DBMS_WORKLOAD_REPLAY: INITIALIZE_REPLAY, PREPARE_REPLAY, and START_REPLAY.

If SCHEDULE_NAME is not NULL, the replay is a new consolidated replay introduced at Oracle Database 11.2.0.4. That is, it is a replay of one or more workload captures done with new APIs at DBMS_WORKLOAD_REPLAY: INITIALIZE_CONSOLIDATED_REPLAY, PREPARE_CONSOLIDATED_REPLAY, and START_CONSOLIDATED_REPLAY.
