You can map errors into an exceptions table. You can use one table for many errors, but you have to code whatever to make the insert work. You can do a one-to-one mapping too, just depends on how granular you want the exceptions table to be. The hard part is making sure you account for expected errors.
-- Specify mapping of exceptions to exceptions table:
MAP <owner>.*, TARGET <owner>.<exceptions>, EXCEPTIONSONLY;
An example shown on pages 96-97 of 11.1 Admin guide:
MAP swilkes.date_test, TARGET swilkes.date_test, &
REPERROR (21000, EXCEPTION), &
SQLEXEC (ID lookup, ON UPDATE, &
QUERY "select count(*) conflict from date_test where t_id = ? and &
t_timestamp > ?", &
PARAMS (p1 = t_id, p2 = t_timestamp), BEFOREFILTER, ERROR REPORT, &
TRACE ALL),&
FILTER (lookup.conflict = 0, ON UPDATE, RAISEERROR 21000);
MAP swilkes.date_test, TARGET swilkes.date_test_exc, EXCEPTIONSONLY, &
INSERTALLRECORDS, &
COLMAP (USEDEFAULTS, errtype = "UPDATE FILTER FAILED.");
An exceptions table could look like:
--8 characters max for the replicat name
--varchar2(30) via object naming rules in Oracle for the table name
--error returned is numeric, and so on
create table ggs_admin.exceptions
( rep_name varchar2(8)
, table_name varchar2(30)
, errno number
, dberrmsg varchar2(4000)
, optype varchar2(20)
, errtype varchar2(20)
, committimestamp timestamp);
