V$GG_APPLY_COORDINATOR

V$GG_APPLY_COORDINATOR displays information about each GoldenGate apply process coordinator. The coordinator for an apply process gets transactions from the apply process reader and passes them to apply servers. An apply process coordinator is a subcomponent of an apply process used by Oracle GoldenGate Integrated Replicat.

Column Datatype Description
SID NUMBER Session ID of the coordinator's session
SERIAL# NUMBER Serial number of the coordinator's session
STATE VARCHAR2(21) State of the coordinator:
  • INITIALIZING - Starting up

  • IDLE - Performing no work

  • APPLYING - Passing transactions to apply servers

  • SHUTTING DOWN CLEANLY - Stopping without an error

  • ABORTING - Stopping because of an apply error

APPLY# NUMBER Apply process number. An apply process coordinator is an Oracle background process, prefixed by ap.
APPLY_NAME VARCHAR2(30) Name of the apply process
TOTAL_APPLIED NUMBER Total number of transactions applied by the apply process since the apply process was last started
TOTAL_WAIT_DEPS NUMBER Number of times since the apply process was last started that an apply server waited to apply a logical change record (LCR) in a transaction until another apply server applied a transaction because of a dependency between the transactions
TOTAL_WAIT_COMMITS NUMBER Number of times since the apply process was last started that an apply server waited to commit a transaction until another apply server committed a transaction to serialize commits
TOTAL_ADMIN NUMBER Number of administrative jobs issued since the apply process was last started
TOTAL_ASSIGNED NUMBER Number of transactions assigned to apply servers since the apply process was last started
TOTAL_RECEIVED NUMBER Total number of transactions received by the coordinator process since the apply process was last started
TOTAL_IGNORED NUMBER Number of transactions which were received by the coordinator but were ignored because they had been previously applied
TOTAL_ROLLBACKS NUMBER Number of transactions which were rolled back due to unexpected contention
TOTAL_ERRORS NUMBER Number of transactions applied by the apply process that resulted in an apply error since the apply process was last started
UNASSIGNED_COMPLETE_TXNS NUMBER Total number of complete transactions that the coordinator has not assigned to any apply servers
LWM_TIME DATE Time when the message with the lowest message number was recorded. The creation time of the message with the lowest message number was also recorded at this time.
LWM_MESSAGE_NUMBER NUMBER Number of the message corresponding to the low watermark. That is, messages with a commit message number less than or equal to this message number have definitely been applied, but some messages with a higher commit message number also may have been applied.
LWM_MESSAGE_CREATE_TIME DATE For captured messages, creation time at the source database of the message corresponding to the low watermark. For user-enqueued messages, time when the message corresponding to the low watermark was enqueued into the queue at the local database.
HWM_TIME DATE Time when the message with the highest message number was recorded. The creation time of the message with the highest message number was also recorded at this time.
HWM_MESSAGE_NUMBER NUMBER Number of the message corresponding to the high watermark. That is, no messages with a commit message number greater than this message number have been applied.
HWM_MESSAGE_CREATE_TIME DATE For captured messages, creation time at the source database of the message corresponding to the high watermark. For user-enqueued messages, time when the message corresponding to the high watermark was enqueued into the queue at the local database.
STARTUP_TIME DATE Time when the apply process was last started
ELAPSED_SCHEDULE_TIME NUMBER Time elapsed (in hundredths of a second) scheduling messages since the apply process was last started
ELAPSED_IDLE_TIME NUMBER Elapsed idle time
LWM_POSITION VARCHAR2(64) Position of the low-watermark LCR
HWM_POSITION VARCHAR2(64) Position of the high-watermark LCR
PROCESSED_MESSAGE_NUMBER NUMBER Message number currently processed by the apply coordinator
ACTIVE_SERVER_COUNT NUMBER Number of apply servers that are being used

Note:

This view is available starting with Oracle Database 11g Release 2 (11.2.0.4).

Note:

The ELAPSED_SCHEDULE_TIME column is only populated if the TIMED_STATISTICS initialization parameter is set to true, or if the STATISTICS_LEVEL initialization parameter is set to TYPICAL or ALL.
