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>];
