Oracle Streams versus GoldenGate

We are testing a system where Oracle Streams has been very problematic. There multiple source databases pointing to a single target. There is the need to change the value of a field so the software on the target recognizes the source.
Oracle streams has been slow during large transaction sets. If a large delete is done on a source it sometimes brings streams down and winds up needing a full refresh.
That being said, one of the solutions suggested is GoldenGate. Does anyone have experience with GoldenGate?

Hello
If you are using RDBMS 10gR2, then this may not be the case. There are several options to enhance the performance and to skip the large transactions etc. If you are sure that there is a large delete the you can make use of TAGs in Oracle Streams so that streams does not capture those transactions:
execute dbms_streams.set_tag(hextoraw('99'));
delete from abc.xyz where ----
execute dbms_streams.set_tag(NULL);
There are lot of options to handle large transactions like apply spilling etc in Oracle 10gR2. So basically you should be optimizing your environment for using Streams.
Also there are tools like SharePlex etc, but I am not much aware of them. Please feel free to share if you have any thoughts.
Thanks,

Oracle streams versus oracle goldengate

Hi all,
I just found out about oracle goldengate and was wondering if anyone of you could share what are the differences between it and oracle streams when it comes to change data capture capabilities? Also, how does owb come into play when it comes to oracle goldengate? For instance owb 11gr2 has got cdc capabilties so does it mean its cdc capabilities is based on oracle streams?

Hi,
With CDC/Streams you have two choices:
process the Oracle logfiles in the source-database/server and read the resulting changerecords from the target database/server or
transport the logfiles to the target database/server and process them there.
The advantage of the latter case is that you relieve the source from the load of processing the logfiles, but target and and source then need to have the same database and server versions. Golden Gate, if I understand correctly, converts the logfiles to its own format (with mimimal load) and these can be processed by Golden Gate on a target database and server of a different version from the source.
So you have the advantage (little load on the source) without the disadvantage (source and target have to be of equal versions).
Regards,
Jaap.

Oracle Streams roadmap

I heard that Oracle Streams will be not implemented in next database versions, because of GoldenGate. Could you provide me any official link that affirm this information? I try to find on google, but can't find any official documents that say that.

Hi;

Help on Oracle streams 11g configuration

Hi Streams experts
Can you please validate the following creation process steps ?
What is need to have streams doing is a one way replication of the AR
schema from a database to another database. Both DML and DDL shall do
the replication of the data.
Help on Oracle streams 11g configuration. I would also need your help
on the maintenance steps, controls and procedures
2 databases
1 src as source database
1 dst as destination database
replication type 1 way of the entire schema FaeterBR
Step 1. Set all databases in archivelog mode.
Step 2. Change initialization parameters for Streams. The Streams pool
size and NLS_DATE_FORMAT require a restart of the instance.
SQL> alter system set global_names=true scope=both;
SQL> alter system set undo_retention=3600 scope=both;
SQL> alter system set job_queue_processes=4 scope=both;
SQL> alter system set streams_pool_size= 20m scope=spfile;
SQL> alter system set NLS_DATE_FORMAT=
'YYYY-MM-DD HH24:MI:SS' scope=spfile;
SQL> shutdown immediate;
SQL> startup
Step 3. Create Streams administrators on the src and dst databases,
and grant required roles and privileges. Create default tablespaces so
that they are not using SYSTEM.
---at the src
SQL> create tablespace streamsdm datafile
'/u01/product/oracle/oradata/orcl/strepadm01.dbf' size 100m;
---at the replica:
SQL> create tablespace streamsdm datafile
---at both sites:
'/u02/oracle/oradata/str10/strepadm01.dbf' size 100m;
SQL> create user streams_adm
identified by streams_adm
default tablespace strepadm01
temporary tablespace temp;
SQL> grant connect, resource, dba, aq_administrator_role to
streams_adm;
SQL> BEGIN
DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE (
grantee => 'streams_adm',
grant_privileges => true);
END;
Step 4. Configure the tnsnames.ora at each site so that a connection
can be made to the other database.
Step 5. With the tnsnames.ora squared away, create a database link for
the streams_adm user at both SRC and DST. With the init parameter
global_name set to True, the db_link name must be the same as the
global_name of the database you are connecting to. Use a SELECT from
the table global_name at each site to determine the global name.
SQL> select * from global_name;
SQL> connect streams_adm/streams_adm@SRC
SQL> create database link DST
connect to streams_adm identified by streams_adm
using 'DST';
SQL> select sysdate from dual@DST;
SLQ> connect streams_adm/streams_adm@DST
SQL> create database link SRC
connect to stream_admin identified by streams_adm
using 'SRC';
SQL> select sysdate from dual@SRC;
Step 6. Control what schema shall be replicated
FaeterBR is the schema to be replicated
Step 7. Add supplemental logging to the FaeterBR schema on all the
tables?
SQL> Alter table FaeterBR.tb1 add supplemental log data
(ALL) columns;
SQL> alter table FaeterBR.tb2 add supplemental log data
(ALL) columns;
etc...
Step 8. Create Streams queues at the primary and replica database.
---at SRC (primary):
SQL> connect stream_admin/stream_admin@ORCL
SQL> BEGIN
DBMS_STREAMS_ADM.SET_UP_QUEUE(
queue_table => 'streams_adm.FaeterBR_src_queue_table',
queue_name => 'streams_adm.FaeterBR_src__queue');
END;
---At DST (replica):
SQL> connect stream_admin/stream_admin@STR10
SQL> BEGIN
DBMS_STREAMS_ADM.SET_UP_QUEUE(
queue_table => 'stream_admin.FaeterBR_dst_queue_table',
queue_name => 'stream_admin.FaeterBR_dst_queue');
END;
Step 9. Create the capture process on the source database (SRC).
SQL> BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name =>'FaeterBR',
streams_type =>'capture',
streams_name =>'FaeterBR_src_capture',
queue_name =>'FaeterBR_src_queue',
include_dml =>true,
include_ddl =>true,
include_tagged_lcr =>false,
source_database => NULL,
inclusion_rule => true);
END;
Step 10. Instantiate the FaeterBR schema at DST. by doing export
import : Can I use now datapump to do that ?
---AT SRC:
exp system/superman file=FaeterBR.dmp log=FaeterBR.log
object_consistent=y owner=FaeterBR
---AT DST:
---Create FaeterBR tablespaces and user:
create tablespace FaeterBR_datafile
'/u02/oracle/oradata/str10/FaeterBR_01.dbf' size 100G;
create tablespace ws_app_idx datafile
'/u02/oracle/oradata/str10/FaeterBR_01.dbf' size 100G;
create user FaeterBR identified by FaeterBR_
default tablespace FaeterBR_
temporary tablespace temp;
grant connect, resource to FaeterBR;
imp system/123db file=FaeterBR_.dmp log=FaeterBR.log fromuser=FaeterBR
touser=FaeterBR streams_instantiation=y
Step 11. Create a propagation job at the source database (SRC).
SQL> BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_PROPAGATION_RULES(
schema_name =>'FaeterBR',
streams_name =>'FaeterBR_src_propagation',
source_queue_name =>'stream_admin.FaeterBR_src_queue',
destination_queue_name=>'stream_admin.FaeterBR_dst_queue@dst',
include_dml =>true,
include_ddl =>true,
include_tagged_lcr =>false,
source_database =>'SRC',
inclusion_rule =>true);
END;
Step 12. Create an apply process at the destination database (DST).
SQL> BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name =>'FaeterBR',
streams_type =>'apply',
streams_name =>'FaeterBR_Dst_apply',
queue_name =>'FaeterBR_dst_queue',
include_dml =>true,
include_ddl =>true,
include_tagged_lcr =>false,
source_database =>'SRC',
inclusion_rule =>true);
END;
Step 13. Create substitution key columns for äll the tables that
haven't a primary key of the FaeterBR schema on DST
The column combination must provide a unique value for Streams.
SQL> BEGIN
DBMS_APPLY_ADM.SET_KEY_COLUMNS(
object_name =>'FaeterBR.tb2',
column_list =>'id1,names,toys,vendor');
END;
Step 14. Configure conflict resolution at the replication db (DST).
Any easier method applicable the schema?
DECLARE
cols DBMS_UTILITY.NAME_ARRAY;
BEGIN
cols(1) := 'id';
cols(2) := 'names';
cols(3) := 'toys';
cols(4) := 'vendor';
DBMS_APPLY_ADM.SET_UPDATE_CONFLICT_HANDLER(
object_name =>'FaeterBR.tb2',
method_name =>'OVERWRITE',
resolution_column=>'FaeterBR',
column_list =>cols);
END;
Step 15. Enable the capture process on the source database (SRC).
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE(
capture_name => 'FaeterBR_src_capture');
END;
Step 16. Enable the apply process on the replication database (DST).
BEGIN
DBMS_APPLY_ADM.START_APPLY(
apply_name => 'FaeterBR_DST_apply');
END;
Step 17. Test streams propagation of rows from source (src) to
replication (DST).
AT ORCL:
insert into FaeterBR.tb2 values (
31000, 'BAMSE', 'DR', 'DR Lejetoej');
AT STR10:
connect FaeterBR/FaeterBR
select * from FaeterBR.tb2 where vendor= 'DR Lejetoej';
Any other test that can be made?

Oracle APEX versus Adobe Flex on AIR

Hi
I need advantages and disadvantages Oracle APEX versus Adobe Flex on AIR. I don't know Adobe and need your help. (we fight about our potential customer).
Project:
40 users insert own actvities into database. Supervisor analyse this info (reports, charts). Users connect to app via mobile phone EDGE using laptop.
Regards

Hello again,
From the end-user perspective, FLEX applicatoins are more graphic in nature, in that they are truly graphic. APEX (at least through 3.2) generates a standard HTML type of web page. You can do graphics type of code, but Flex creates applications that will only run with Adobe tools. Flex generates an HTML page, but it calls a .swf file and plays that.
Unless it is critical that you have that fully graphic interface (a .swf file type of image that plays), standard HTML is much better. You can still generate graphs, charts and such; incorporate images in your page and all the things that standard web pages have.
With APEX, your users will see a standard HTML web-page type of interface, which most users today know how to use and expect.
Thanks,
Don.

Oracle streams configuration problem

Hi all,
i'm trying to configure oracle stream to my source database (oracle 9.2) and when i execute the package DBMS_LOGMNR_D.SET_TABLESPACE('LOGMNRTS'); i got an error bellow:
ERROR at line 1:
ORA-01353: existing Logminer session

When checking some docs, they told i have to destraoy all logminer session, and i verify to v$session view and cannot identify logminer session. If someone can help me because i need this sttream tools for schema synchronization of my production database and datawarehouse database.
That i want is how to destroy or stop logminer session.
Thnaks for your help

Thanks Werner, it's ok now my problem is solved and here bellow the output of your script.
I profit if you have some docs or some advise for my database schema synchronisation, is using oracle sctrems is the best or can i use anything else but not Dataguard concept or standby database because i only want to apply DMl changes not DDL. If you have some docs for Oracle streams and especially for schema synchronization not tables.
many thanks again, and please send to my email address [email protected] if needed

Open a pdf from a buffered stream versus file system?

With the PDF Library SDK is it possible to open a pdf from a stream versus the file system?

Yes, but not trivially. You would have to implement your own
ASFileSys, which is a method for accessing "files". This is a
collection of methods, rather like an object oriented class, but in C.
You would have to support get, put, open, random access, file naming
etc.

Oracle Streaming in same database - 10g

Oracle Streaming in 10g database
Posted: Sep 21, 2006 4:25 AM Reply
Hello,
I am trying do streaming at table level for all dml changes from one schema(source) to another schema (target) controlled by admin schema (stream_admin). I have all these schemas in same database(10g-enterprise edition).
As given in documentations , I created
1. two queues(in_Q and out_Q) in Stream_admin,
2. two process( capture and apply process) in Stream_admin ,
3. A propagation rule for propagation between in_Q and out_Q,
4. did instantiation,
5. started both capture and apply process.
Having done that , I insert in source table and check for the same in target but alas!! nothing happens. I fail to achieve streaming.
I am not getting any error. Neither in process , nor in propagation or queues. And all queues,rules and process are enabled.
Please help.

datapump uses dbms_metadata extensively.
Problem is twofold
- the amount of data
- why on earth do you need to 'copy' these 1.2 Tb a 'number of times'
One would expect you would have tested the upgrade on a smaller test database. and you wouldn't need to fix bugs in a 1.2 Tb database.
A better idea would be to duplicate the complete database using RMAN. This doesn't perform conventional INSERTs and doesn't create redo.

Here is my problem:
After i configured it the streams still cannot replicate. And when I checked the EM GUI for streams monitoring it displays a broken database link.
Also it says that the database link is not active.
Can anyone please help?
Thanks.

I don't know what Datacomp is, but you should be able
to connect to any non-Oracle database if there is
an ODBC driver for it. You would use Generic
Heterogeneous Services to do this. See the following
link to the documentation for details:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96544/gencon.htm#1656
There are also several articles on the Net. Do a google
search on oracle generic heterogeneous services /
connectivity.
Hope this helps.

Oracle Streams 'ORA-25215: user_data type and queue type do not match'

I am trying replication between two databases (10.2.0.3) using Oracle Streams.
I have followed the instructions at http://www.oracle.com/technology/oramag/oracle/04-nov/o64streams.html
The main steps are:
1. Set up ARCHIVELOG mode.
2. Set up the Streams administrator.
3. Set initialization parameters.
4. Create a database link.
5. Set up source and destination queues.
6. Set up supplemental logging at the source database.
7. Configure the capture process at the source database.
8. Configure the propagation process.
9. Create the destination table.
10. Grant object privileges.
11. Set the instantiation system change number (SCN).
12. Configure the apply process at the destination database.
13. Start the capture and apply processes.
For step 5, I have used the 'set_up_queue' in the 'dbms_strems_adm package'. This procedure creates a queue table and an associated queue.
The problem is that, in the propagation process, I get this error:
'ORA-25215: user_data type and queue type do not match'
I have checked it, and the queue table and its associated queue are created as shown:
sys.dbms_aqadm.create_queue_table (
queue_table => 'CAPTURE_SFQTAB'
, queue_payload_type => 'SYS.ANYDATA'
, sort_list => ''
, COMMENT => ''
, multiple_consumers => TRUE
, message_grouping => DBMS_AQADM.TRANSACTIONAL
, storage_clause => 'TABLESPACE STREAMSTS LOGGING'
, compatible => '8.1'
, primary_instance => '0'
, secondary_instance => '0');
sys.dbms_aqadm.create_queue(
queue_name => 'CAPTURE_SFQ'
, queue_table => 'CAPTURE_SFQTAB'
, queue_type => sys.dbms_aqadm.NORMAL_QUEUE
, max_retries => '5'
, retry_delay => '0'
, retention_time => '0'
, COMMENT => '');
The capture process is 'capturing changes' but it seems that these changes cannot be enqueued into the capture queue because the data type is not correct.
As far as I know, 'sys.anydata' payload type and 'normal_queue' type are the right parameters to get a successful configuration.
I would be really grateful for any idea!

Hi
You need to run a VERIFY to make sure that the queues are compatible. At least on my 10.2.0.3/4 I need to do it.
DECLARE
rc BINARY_INTEGER;
BEGIN
DBMS_AQADM.VERIFY_QUEUE_TYPES(
src_queue_name => 'np_out_onlinex',
dest_queue_name => 'np_out_onlinex',
rc => rc, , destination => 'scnp.pfa.dk',
transformation => 'TransformDim2JMS_001x');
DBMS_OUTPUT.PUT_LINE('Compatible: '||rc);
If you dont have transformations and/or a remote destination - then delete those params.
Check the table: SYS.AQ$_MESSAGE_TYPES there you can see what are verified or not

Oracle Streams Update conflict handler not working

Hello,
I've been working on the Oracle streams and this time we've to come up with Update conflict handler.
We are using Oracle 11g on Solaris10 env.
So far, we have implemented bi-directional Oracle Streams Replication and it is working fine.
Now, when i try to implement Update conflict handler - it executed successfully but it is not fulfilling the desired functionality.
Here are the steps i performed:
Steap -1:

cols(4) := 'time';
DBMS_APPLY_ADM.SET_UPDATE_CONFLICT_HANDLER(
object_name => 'jas23.test73',
method_name => 'MAXIMUM',
resolution_column => 'time',
column_list => cols);
END;
Step-4
conn to strmadmin/strmadmin to server2
SQL>
DECLARE
cols DBMS_UTILITY.NAME_ARRAY;
BEGIN
cols(1) := 'first_name';
cols(2) := 'last_name';
cols(3) := 'salary';
cols(4) := 'time';
DBMS_APPLY_ADM.SET_UPDATE_CONFLICT_HANDLER(
object_name => 'jas23.test73',
method_name => 'MAXIMUM',
resolution_column => 'time',
column_list => cols);
END;
Step-5
And now, if i try to update the value of salary, then it is not getting handled by update conflict handler.
update jas23.test73 set salary = 1500,time=SYSTIMESTAMP where first_name='papa'; --server1
update jas23.test73 set salary = 2500,time=SYSTIMESTAMP where first_name='papa'; --server2
commit; --server1
commit; --server2
Note: Both the servers are into different timezone (i hope it wont be any problem)
Now, after performing all these steps - the data is not same at both sites.
Error(DBA_APPLY_ERROR) -
ORA-26787: The row with key ("FIRST_NAME", "LAST_NAME", "SALARY", "TIME") = (papa, sdds, 2000, 23-DEC-10 05.46.18.994233000 PM +00:00) does not exist in ta
ble JAS23.TEST73
ORA-01403: no data found
Please help.
Thanks.

Hi,
When i tried to do it on Server-2:
SQL> ALTER TABLE jas23.test73 ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
it throws me an error,
Error -
ERROR at line 1:
ORA-32588: supplemental logging attribute all column exists
