How to recreate capture for oracle 10gR2 in window

Question

Hi Experts,
After I got the archived issues, I restarted capture process in vmsdbhq by strmadmin account and then I saw the messages as: WAITING FOR REDO: LAST SCN MINED 6134217037123.
SQL> DECLARE
2 -- Declare variable to hold instantiation SCN
3 iscn NUMBER;
4 BEGIN
5 iscn:=DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
6 DBMS_OUTPUT.PUT_LINE ('Instantiation SCN is: ' || iscn);
7 END;
8 /
Instantiation SCN is: 6134217223400
SQL> begin
2 DBMS_cAPTURE_ADM.ALTER_CAPTURE(
3 capture_name => 'STREAM_CAPTURE',
4 start_scn => 6134217223400,
5 first_scn => 6134217223400);
6 end;
7 /
begin
ERROR at line 1:

ORA-06512: at "SYS.DBMS_CAPTURE_ADM", line 212
ORA-06512: at line 2
PL/SQL procedure successfully completed.
I got advice to recreate this capture.
How to recreate a capture? May I have a procedure in detail? which difference between recreate capture and create capture?
Or i need to stop propagation during using alter exist capture?
If drop capture, do I need to all capture steps?
I am new person in here
Thanks for your help!

+" which difference between recreate capture and create capture?"+
No major difference.
Create capture - You are creating capture process for the first time.
Recreate capture - You are dropping capture process and creating it again..
To recreate capture process, first you have to stop associated propagation and apply process.
than stop and drop the exising capture process. You can follow the same procedure as you followed for creating the capture process initially..
See following example, followed by me for the same:
1) stop capture process
BEGIN
DBMS_CAPTURE_ADM.STOP_CAPTURE(
capture_name => 'APPS_CAPTURE');
END;
2) Stop propagation process.
Execute following command as stream administrator from primary database.
BEGIN
DBMS_PROPAGATION_ADM.STOP_PROPAGATION(
propagation_name => 'APPS_PROP');
END;
3) Stop apply process.
Execute following command as stream administrator from replica database.
BEGIN
DBMS_APPLY_ADM.STOP_APPLY(
apply_name => 'APPS_APPLY');
END;
4) drop capture process
BEGIN
DBMS_CAPTURE_ADM.DROP_CAPTURE(
capture_name => 'APPS_CAPTURE',
drop_unused_rule_sets => true);
END;
5) check table status. (as sys user)
select count(*) from dba_objects where object_name like 'APPS_CAP_TABLE';
6) ----check rules (our rule is:
SELECT rule_owner, rule_name FROM dba_rules
7) ----create capture process
begin
DBMS_CAPTURE_ADM.CREATE_CAPTURE(
queue_name => 'APPS_CAP_QUEUE',
capture_name => 'APPS_CAPTURE',
rule_set_name => NULL,
start_scn => NULL,
source_database => 'AQPROD',
use_database_link => FALSE,
first_scn => NULL,
logfile_assignment => 'implicit',
negative_rule_set_name => NULL,
capture_user => NULL,
checkpoint_retention_time => 6);
end;
8) --------START CAPTURE PROCESS
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE(
capture_name => 'APPS_CAPTURE');
END;
9) --------START PROPAGATION PROCESS
BEGIN
DBMS_PROPAGATION_ADM.START_PROPAGATION(
capture_name => 'APPS_PROP');
END;
10) Start apply process.
Execute following command as stream administrator from replica database.
BEGIN
DBMS_APPLY_ADM.START_APPLY(
apply_name => 'APPS_APPLY');
END;
HTH.
