一、理论

source

ADD EXTRACT <ext>, TRANLOG, BEGIN <time>, [, THREADS]

ADD EXTTRAIL <local_trail>, EXTRACT <ext>

EDIT PARAMS <ext>

-- Identify the Extract group:

EXTRACT <ext>

-- Specify database login information as needed for the database:

[SOURCEDB <dsn_1>,][USERID <user>[, PASSWORD <pw>]]

-- Specify the local trail that this Extract writes to:

EXTTRAIL <local_trail>

-- Specify tables to be captured:

TABLE <owner>.<table>;

ADD EXTRACT <pump_1>, EXTTRAILSOURCE <local_trail>, BEGIN <time>

ADD RMTTRAIL <remote_trail_1>, EXTRACT <pump_1>

EDIT PARAMS <pump_1>

-- Identify the data pump group:

EXTRACT <pump_1>

-- Specify database login information as needed for the database:

[SOURCEDB <dsn_1>,][USERID <user>[, PASSWORD <pw>]]

-- Specify the name or IP address of the first target system:

RMTHOST <target_1>, MGRPORT <portnumber>

-- Specify the remote trail on the first target system:

RMTTRAIL <remote_trail_1>

-- Allow mapping, filtering, conversion or pass data through as-is:

[PASSTHRU | NOPASSTHRU]

-- Specify tables to be captured:

TABLE <owner>.<table>;

target

edit params ./GLOBALS

CHECKPOINTTABLE <owner>.<tablename>

ADD REPLICAT <rep_1>, EXTTRAIL <remote_trail_1>, BEGIN <time> checkpointtable <owner>.<tablename>

edit params <rep_1>

-- Identify the Replicat group:

REPLICAT <rep_1>

-- State whether or not source and target definitions are identical:

SOURCEDEFS <full_pathname> | ASSUMETARGETDEFS

-- Specify database login information as needed for the database:

[TARGETDB <dsn_3>,] [USERID <user id>[, PASSWORD <pw>]]

-- Specify error handling rules:

REPERROR (<error>, <response>)

-- Specify tables for delivery:

MAP <owner>.<table>, TARGET <owner>.<table>[, DEF <template name>];
