Delete blob column in source and rename schema using rule

Question

Hi
I have blob column in source table, which i am deleting while capturing through rule based tranformation and also renaming the schema through the same rule.
SET SERVEROUTPUT ON
DECLARE
v_dml_rule VARCHAR2(80);
v_ddl_rule VARCHAR2(80);
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'ENGINE.ACTIVATIONS',
streams_type => 'CAPTURE',
streams_name => 'CAPTURE_TO_&destsid',
queue_name => '&source_strmadmin_user..&sourcesid._TO_&destsid',
include_dml => true,
include_ddl => false,
include_tagged_lcr => false,
source_database => 'MMSTG.DEMOWORLD.COM',
dml_rule_name => v_dml_rule,
ddl_rule_name => v_ddl_rule,
and_condition => ':lcr.get_command_type() != ''DELETE''',
inclusion_rule => true);
DBMS_STREAMS_ADM.DELETE_COLUMN(
rule_name => v_dml_rule,
table_name => 'ENGINE.ACTIVATIOINS',
column_name => 'INSTANCE_DATA',
value_type => '*',
step_number => 0,
operation => 'ADD');
DBMS_STREAMS_ADM.RENAME_SCHEMA(
rule_name => v_dml_rule,
from_schema_name => 'ENGINE',
to_schema_name => 'ENGINE_WEST',
step_number => 0,
operation => 'ADD');
DBMS_OUTPUT.PUT_LINE('Capture DML Rule for ENGINE.ACTIVATIOINS => ' || v_dml_rule);
END;
I use step_number 0 for both rename schema and delete column. Some how, delete column transformation is not firing and it replicates the blob column with some bytes instead of zero bytes.
How do we execute this both rule based transformation with correct step_number to fire both transformations. Please do let me know..
Thanks

Answer 1

In what version?
Step 0 is the default so that is not the issue.
Can you also post the DDL for your table and the results of the following query:
SELECT *
FROM dba_streams_unsupported
WHERE owner = <schema owner>
AND table_name = <your table name>;
