RULE_SET_NAME

VARCHAR2(128)

  

Name of the positive rule set used by the capture process for filtering

CAPTURE_USER

VARCHAR2(128)

  

Current user who is enqueuing captured messages

START_SCN

NUMBER

STATUS

  • ENABLED

  • ABORTED

CAPTURED_SCN

NUMBER

  

System change number (SCN) of the last redo log record scanned

APPLIED_SCN

USE_DATABASE_LINK

VARCHAR2(3)

  

Indicates whether the source database name is used as the database link to connect to the source database from the downstream database (YES) or not (NO). If the capture process was created at the source database, then this column will be NULL.

FIRST_SCN

NUMBER

  

System change number (SCN) from which the capture process can be restarted. FIRST_SCN indicates the lowest SCN to which the capture can be repositioned.

SOURCE_DATABASE

VARCHAR2(128)

  

Global name of the source database

SOURCE_DBID

NUMBER

  

Database ID of the source database

SOURCE_RESETLOGS_SCN

NUMBER

  

Resetlogs system change number (SCN) of the source database

NUMBER

  

Resetlogs time of the source database

LOGMINER_ID

NUMBER

  

Session ID of the Oracle LogMiner session associated with the capture process

VARCHAR2(128)

  

Name of the negative rule set used by the capture process for filtering

NEGATIVE_RULE_SET_OWNER

VARCHAR2(128)

  

Owner of the negative rule set used by the capture process for filtering

MAX_CHECKPOINT_SCN

NUMBER

  

System change number (SCN) at which the last checkpoint was taken by the capture process

REQUIRED_CHECKPOINT_SCN

NUMBER

  

Lowest checkpoint SCN for which the capture process requires redo information.

Note: This SCN value does not necessarily correspond with a checkpoint SCN value.

LOGFILE_ASSIGNMENT

VARCHAR2(8)

  

Logfile assignment type for the capture process:

  • IMPLICIT

  • EXPLICIT

STATUS_CHANGE_TIME

DATE

  

Time that the STATUS of the capture process was changed

Error number if the capture process was aborted

ERROR_MESSAGE

VARCHAR2(4000)

  

Error message if the capture process was aborted

VERSION

VARCHAR2(64)

  

Version number of the capture process

CAPTURE_TYPE

VARCHAR2(10)

  

Type of the capture process:

  • DOWNSTREAM

  • LOCAL

LAST_ENQUEUED_SCN

NUMBER

  

Last enqueued system change number (SCN)

CHECKPOINT_RETENTION_TIME

NUMBER

  

Checkpoint retention time

Note: When the checkpoint retention time for a capture process is set to INFINITE, then the value displayed in this column is 4294967295.

START_TIME

TIMESTAMP(6)

  

Time from which the capture process will start to capture changes. START_TIME is related to START_SCN and can only be modified by an ALTER_CAPTURE statement.

You can modify either START_SCN or START_TIME, but not both at the same time.

PURPOSE

VARCHAR2(19)

  

Purpose of the capture process:

  • GoldenGate Capture - A capture process configured using Oracle GoldenGate Extract in integrated capture mode

  • Streams - A capture process in an Oracle Streams configuration

  • XStream Streams - A capture process in an Oracle Streams configuration with XStream capabilities enabled by the DBMS_XSTREAM_ADM.ENABLE_GG_XSTREAM_FOR_STREAMS procedure

  • XStream Out - A capture process in an XStream Out configuration

  • AUDIT VAULT - A capture process in an audit vault configuration

SOURCE_ROOT_NAME

VARCHAR2(128)

  

The global name of the source root database

CLIENT_NAME

VARCHAR2(4000)

  

Client name of the capture process. This is the outbound name for XStream Out, and the extract name for GoldenGate.

CLIENT_STATUS

VARCHAR2(8)

  

Status of the client process:

  • DISABLED - For XStream Out if the outbound server is not running; for GoldenGate if the capture process is not running

  • DETACHED - For XStream Out if the outbound server is running, but the XStream client application is not attached to it; For GoldenGate if the capture process is running, but the extract process is not attached to it

  • ATTACHED - For XStream out if the outbound server is running and the XStream client application is attached to it; For GoldenGate if the capture process is running and the extract process is attached to it

  • ABORTED - For XStream out if the outbound server became disabled because it encountered an error; for GoldenGate if the capture process became disabled because it encountered an error

OLDEST_SCN

NUMBER

  

Oldest SCN of the transactions currently being processed

FILTERED_SCN

NUMBER

  

SCN of the low watermark transaction processed
