How to exclude tables from Schema level replication

Question

Hi All,
I am currently trying to setup Oracle Streams (Oracle 11.1.0.6 on RHEL5) to replicate a schema from one instance to another.
The basic schema level replication is working well, and copying DDL and DML changes without any problems. However there are a couple of tables that I need to exclude from the stream, due to incompatible datatypes.
Does anybody have any ideas or notes on how I could achieve this?? I have been reading the Oracle documentation and find it difficult to follow and confusing, and I have not found any examples in the internet.
Thanks heaps.
Gavin

When you use SCHEMA level rules for capture and need to skip the replication of a few tables, you create rules in the negative rule set for the table.
Here is an example of creating table rules in the negative rule set for the capture process.
begin
dbms_streams_adm.add_table_rules(
table_name => 'schema.table_to_be_skipped',
streams_type => 'CAPTURE',
streams_name => 'your_capture_name',
queue_name => 'strmadmin.capture_queue_name',
include_dml => true,
include_ddl => true,
inclusion_rule => false
end;
table_name parameter identifies the fully qualified table name (schema.table)
streams_name identifies the capture process for which the rules are to be added
queue_name specifies the name of the queue associated with the capture process.
Inclusion_rule=> false indicates that the create rules are to be placed in the negative rule set (ie, skip this table)
include_dml=> true indicates DML changes for the table (ie, skip DML changes for this table)
include_ddl=> true indicates DDL changes for the table (ie, skip DDL changes for this table)
