7.252 V$GOLDENGATE_CAPTURE

V$GOLDENGATE_CAPTURE displays information about each capture process that sends LCRs to an Oracle GoldenGate outbound server.

Column	Datatype	Description
SID	NUMBER	Session identifier of the capture process
SERIAL#	NUMBER	Session serial number of the capture process session
CAPTURE#	NUMBER	Capture process number. A capture process is an Oracle background process prefixed by cp
CAPTURE_NAME	VARCHAR2(128)	Name of the capture process
LOGMINER_ID	NUMBER	Session ID of the Oracle LogMiner session associated with the capture process
STARTUP_TIME	DATE	Time when the capture process was last started
STATE	VARCHAR2(589)	State of the capture process and state of the network. The two states are separated by a semicolon. The possible values are: INITIALIZING - Starting up. WAITING FOR DICTIONARY REDO - Waiting for redo log files containing the dictionary build related to the first SCN to be added to the capture process session. A capture process cannot begin to scan the redo log files until all of the log files containing the dictionary build have been added. DICTIONARY INITIALIZATION - Processing a dictionary build. MINING (PROCESSED SCN = scn_value) - Mining a dictionary build at the SCN scn_value. LOADING (step X of Y) - Processing information from a dictionary build and currently at step X in a process that involves Y steps, where X and Y are numbers. CAPTURING CHANGES - Scanning the redo log for changes that satisfy the capture process rule sets. WAITING FOR REDO - Waiting for new redo log files to be added to the capture process session. The capture process has finished processing all of the redo log files added to its session. This state is possible if there is no activity at a source database. For a downstream capture process, this state is possible if the capture process is waiting for new log files to be added to its session. EVALUATING RULE - Evaluating a change against a capture process rule set. CREATING LCR - Converting a change into an LCR. ENQUEUING MESSAGE - Enqueuing an LCR that satisfies the capture process rule sets into the capture process queue. PAUSED FOR FLOW CONTROL - Unable to enqueue LCRs either because of low memory or because propagations and outbound servers are consuming messages slower than the capture process is creating them. This state indicates flow control that is used to reduce spilling of captured LCRs when propagation or apply has fallen behind or is unavailable. WAITING FOR THE BUFFERED QUEUE TO SHRINK - Waiting for the buffered queue to change to a smaller size. The buffered queue shrinks when there is a memory limitation or when an administrator reduces its size. WAITING FOR n SUBSCRIBER(S) INITIALIZING - Waiting for outbound servers that receive LCRs from the capture process to start, where n is the number of apply processes. WAITING FOR TRANSACTION - Waiting for LogMiner to provide more transactions. WAITING FOR INACTIVE DEQUEUERS - Waiting for the capture process's queue subscribers to start. The capture process stops enqueuing LCRs if there are no active subscribers to the queue. SUSPENDED FOR AUTO SPLIT/MERGE - Waiting for a merge operation to complete. SHUTTING DOWN - Stopping. ABORTING - Aborting.
TOTAL_PREFILTER_DISCARDED	NUMBER	Total number of prefiltered messages discarded
TOTAL_PREFILTER_KEPT	NUMBER	Total number of prefiltered messages kept
TOTAL_PREFILTER_EVALUATIONS	NUMBER	Total number of prefilter evaluations
TOTAL_MESSAGES_CAPTURED	NUMBER	Total number of redo entries passed by LogMiner to the capture process for detailed rule evaluation since the capture process last started. A capture process converts a redo entry into a message and performs detailed rule evaluation on the message when capture process prefiltering cannot discard the change.
CAPTURE_TIME	DATE	Time when the most recent message was captured
CAPTURE_MESSAGE_NUMBER	NUMBER	Number of the most recently captured message
CAPTURE_MESSAGE_CREATE_TIME	DATE	Creation time of the most recently captured message
TOTAL_MESSAGES_CREATED	NUMBER	Count associated with ELAPSED_LCR_TIME to calculate rate
TOTAL_FULL_EVALUATIONS	NUMBER	Count associated with ELAPSED_RULE_TIME to calculate rate
TOTAL_MESSAGES_ENQUEUED	NUMBER	Total number of messages enqueued since the capture process was last started
ENQUEUE_TIME	DATE	Time when the last message was enqueued
ENQUEUE_MESSAGE_NUMBER	NUMBER	Number of the last enqueued message
ENQUEUE_MESSAGE_CREATE_TIME	DATE	Creation time of the last enqueued message
AVAILABLE_MESSAGE_NUMBER	NUMBER	For local capture, the last redo SCN flushed to the log files. For downstream capture, the last SCN added to LogMiner through the archived redo log files.
AVAILABLE_MESSAGE_CREATE_TIME	DATE	For local capture, the time the SCN was written to the log file. For downstream capture, the time the most recent archived redo log file (containing the most recent SCN) was added to LogMiner.
ELAPSED_CAPTURE_TIME	NUMBER	Elapsed time (in hundredths of a second) scanning for changes in the redo log since the capture process was last started
ELAPSED_RULE_TIME	NUMBER	Elapsed time (in hundredths of a second) evaluating rules since the capture process was last started
ELAPSED_ENQUEUE_TIME	NUMBER	Elapsed time (in hundredths of a second) enqueuing messages since the capture process was last started
ELAPSED_LCR_TIME	NUMBER	Elapsed time (in hundredths of a second) creating LCRs since the capture process was last started
ELAPSED_REDO_WAIT_TIME	NUMBER	Elapsed time (in hundredths of a second) spent by the capture process in the WAITING FOR REDO state
ELAPSED_PAUSE_TIME	NUMBER	Elapsed flow control pause time (in hundredths of a second)
STATE_CHANGED_TIME	DATE	Time at which the state of the capture process changed
SGA_USED	NUMBER	The total amount of shared memory used (in bytes) by the capture process
SGA_ALLOCATED	NUMBER	The total amount of shared memory (in bytes) allocated from the Streams pool for the capture process
BYTES_OF_REDO_MINED	VARCHAR2(64)	The total amount of redo data mined (in bytes) since the capture process last started
SESSION_RESTART_SCN	VARCHAR2(64)	The SCN from which the capture process started mining redo data when it was last started
CON_ID	NUMBER	The ID of the container to which the data pertains. Possible values include: 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs. 1: This value is used for rows containing data that pertain to only the root n: Where n is the applicable container ID for the rows containing data
SPID	VARCHAR2(12)	Operating system process identifier of the capture process
EXTRACT_NAME	VARCHAR2(128)	Name of the extract process
SERVER_SID	NUMBER	Session ID of the capture server
SERVER_SERIAL#	NUMBER	Session serial number of the capture server
SERVER_SPID	VARCHAR2(12)	Operating system process identifier of the capture server
TOTAL_MESSAGES_SENT	NUMBER	Total number of LCRs sent by the capture process to the GoldenGate extract process since the last time the extract attached to the capture
SEND_TIME	DATE	Time the last LCR was sent by the capture process to the extract process
LAST_SENT_MESSAGE_NUMBER	NUMBER	Message number of the last LCR sent by the capture process to the extract process
LAST_SENT_MESSAGE_CREATE_TIME	DATE	Creation time at the source database of the last LCR sent by the capture process to the extract process
ELAPSED_SEND_TIME	NUMBER	Time elapsed (in hundredths of a second) sending LCRs to the extract process since the last time the extract process attached to the capture process
BYTES_SENT	NUMBER	Total number of bytes sent by the capture process to the extract process since the last time the extract process attached to the capture process
