Help for materialized View & Streams.

Hi all,
I am confused....I thought streams is replacing materialized view and replication :(
What are the difference between "streams", "advance replication", and "mat. views"?
Thanks a lot,

My boss ask me to replicate a table (with image column - picture of a person) which comes from sql server database to and oracle database.Well, presumably you informed your boss that you didn't know how to accomplish the task and that it would take some time for you to learn. And hopefully your estimates included sufficient padding to account for the fact that you'll be reading a lot of documentation.
What do I do :( . Can I use mat. views + streams + advance repl? also dbvisit? Can you use materialized views? Sure.
Can you use Streams? Sure.
You could also use GoldenGate which is the technology Oracle has depricated Streams in favor of.
I'm not sure that I see why you would want to use advanced replication unless you intend on doing bidirectional replication.
I have no idea what dbvisit is. That doesn't sound like an Oracle technology.

You should read chapters 8 & 9 of the Data Warehousing Guide:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28313/basicmv.htm
Just saying "you need a materialized view" doesn't provide enough information on what you need or how you plan to use it.

Setting DBMS_METADATA.GET_DDL Output for Materialized Views

Hi all.
My Oracle version is 10g.
I'm extracting the DDL of all the objects from database using the DBMS_METADATA package. I'm using SET_TRANSFORM_PARAM to configure the output because I need a simple sql code, without information about tablespaces, storage and segment attributes. Everything works fine except when I'm working with mviews object types. I can't remove the information about tablespace, storage or segment attributes for materialized views.
I would like to know if there's a related issue about it. Or there's something missing in my code?
I tried to specify the object type as another parameter on DBMS_METADATA.SET_TRANSFORM_PARAM but don't work too.
The only transform parameter that works fine with Materialized Views is the SQLTERMINATOR.
See how I have done:
declare
vDDL clob;
begin
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'STORAGE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'TABLESPACE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SEGMENT_ATTRIBUTES', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SQLTERMINATOR',TRUE);
select dbms_metadata.get_ddl ('MATERIALIZED_VIEW', 'MV_STO020', 'HIS117_CHECK') into vDDL FROM DUAL;
dbms_output.put_line (vDDL);
end;
and how the output is:
CREATE MATERIALIZED VIEW "HIS117_CHECK"."MV_STO020"

Right. I found this way but I consider this just a quick fix, because I think there should be a better way to do this.
create table t_clob (c_long);
declare
p clob;
begin
delete from t_clob;
execute immediate 'insert into t_clob (select to_lob(query) from dba_mviews where owner = :1 and mview_name = :2)'

select 'CREATE MATERIALIZED VIEW MV_STO020' || chr(10) ||

Help needed in query for Materialized View

Hi,
I want to create a materialized view which has some precalcultaed values.
I have four dimension tables out of which one is a Time Dimension table with levels as Year->Quarter->Month.
The precalculations are the moving averages and cummulative values of Sales Amt on the dimension values over a period of 4 Months.
The dimension tables are Clients, Products, Channel, Time.
Fact Table is Sales_Fact which will have the sales amount for different members of the dimension.
Since my fact table is very huge, i want to create a materialized view where i could store the required calculated measures, here Moving Average of Sales Amt for each Client, Product, Channel dimensions over a period of 4 Months.
Can anybody help with writing the query for this..Any help in this regard will be appreciated..
Please give me suggestions for this..

Search help for Material long text ?

Hello,
A given material code MATNR is linked a material short text ( MAKT_MAKTG for example) which is on max 40 characters.
Where can i maintain the material long text ( around 100 characters) which is available in a search help in standard SAP ?
Note : in the material master data, i know the view Purchase order text, but is there any search help for this ?
Or do you have to develop an own search help ?
Thank you in advance,
Isabelle

Thank you Jürgen,
OK, i understand that a search help on long text is not a good idea
Nevertheless, 40 characters to name a material is too short for our users. Do you know any other text field that we can use ? because i imagine it is not possible to extend MAKTG to more that 40 char.
Our issue is that we upload our material data from some manufacturer material file, and their material description (even the one called " short text" is often more than 40 char.
Do you see any possible solution ?
Thank you,
Isabelle

Search Help for Material Master

We would like to have a search help for the material master.
This should help me search the materials which have the product hierarchy field filled.
Please let me know if the below steps are correct.
1)Create a new Match Code say zMAT_prod
2)Add the match Code zMAT_prod to MAT1_A collective search help.

Hi Rohita,
Adding Matcode Id is correct...You can add this matchcode ID in the selection screen.
Also before adding the Matchcode ID ...You may need to write a select query with the condition to populate the data into that view.
Ex :
select single vbeln
           from vbak
                   into table t_matchcode
                   where vbak = xyz "give any condition which you wish to extract the data.
Suppose Matchcode Id is ZTA.
Select-options : s_vbeln for vbak-vbeln matcode id ZTA
So that it will display the Serach help with all the details.

Kittu

Refresh time for Materialized View

Explain Plan for Materialized Views in 10g

I am verifying explain plan for few queries on 10g as compared to 9i I was wondering in Materialized Views queries MAT_VIEW ACCESS instead of TABLE ACCESS is it expected behaviour or am missing something?
Couldn't find information in 10g documentation
thanks in advance

I've put together a query for the v$sql_plan in 9iR2.
Depending on what you use, you can probably drop some columns (eg OTHER and partition columns) and you could drive it from the v$session by getting the hash_value from there for the sid you are interested in :
(select * from v$sql_plan where hash_value =
(select sql_hash_value from v$session where sid=:sid))
select level, optimizer, lpad('_',1*(level-1),'_')||operation operation,
options, object_owner||'.'||object_name obj_name, search_columns,
ltrim(to_char(cardinality,'999,999,999')) no_rows,
ltrim(to_char(bytes/1024,'999,999')) kbytes, cost tot_cost,
object_node link, id, parent_id, other_tag||':'||other other,
partition_start, partition_stop, cpu_cost, io_cost,
access_predicates, filter_predicates,
round(temp_space/(1024*1024),2) temp_space_mb
from (select * from v$sql_plan where hash_value = :hash_val)
start with id=0
connect by prior id = parent_id and prior child_number = child_number
order by child_number, id, position;

WHERE clause for Materialized View

Hi,
We are replicating a very large table from Production. The table is approx 40Gb in size and so the DBA's are very reluctant to do a full replication as it could bring down the production server (I'm a developer so I'm going on faith this is correct).
I have been looking for a way to limit the number of columns that I need, approx 1 weeks data is enough to begin with. The table has a column txntimestamp which I am trying to use in the WHERE
create materialized view FWWIPTRANSACTION
refresh fast on demand   with rowid
as select * from WLOS_OWNER.WAFPROD_FWWIPTRANSACTION
where txntimestamp > '20/06/2009 07:00:00'But I recieve the error
ORA-12015: cannot create a fast refresh materialized view from a complex queryDoes anyone know a way around this? This is the only date field I can use and pretty much the only viable option to limit the number of rows.
Thank You.

Sorry for jumping ahead but if I was able to get
create materialized view FWWIPTRANSACTION
refresh fast on demand   with rowid
as select * from [email protected]
      where txntimestamp > '20/06/2009 07:00:00';to work, does this mean every time this MV refreshes it brings across everything since that date or merely the new rows since the last refresh? If so I will need a rolling clause i.e. sysdate - 30

Please help on Materialized View

Hello everyone,
Our Oracle database is 11g Standard Edition, and need to create the Mviews for the data replication. We are going to use Refresh Fast, and manually to refresh Mviews with cron job.
We have one Mview, which is created based on four master tables joined together. With "Refresh Fast" mode and join option, there are some restrictions. One of them is all ROWIDs of the base tables must be listed in SELECT statement. So that we have to add four extra ROWID columns in the MView. Is there a way to get rid of them? Please give some suggestions.
Here is our test, and we do not want "e.rowid col1, d.rowid col2" in the MView.
Thanks in advance!!!
create table emp (empid number, name varchar2(10), deptno number);
alter table emp add constraint emp_pk primary key (empid);
create table dept (deptno number, name varchar2(10));
alter table dept add constraint dept_pk primary key (deptno);
alter table emp add constraint emp_fk foreign key (deptno)
REFERENCES dept (deptno);
create materialized view log on emp with rowid, sequence(empid, name, deptno) including new values;
create materialized view log on dept with rowid, sequence(deptno, name) including new values;
create materialized view emp_dept_mv

where e.deptno=d.deptno;
Materialized view created.

Hi,
First thing is that, I could not able to understand what is the use of manual refresh.??
As you have gone of Refresh Fast that is more than enough for your requirement, If am correct with the things what you stated in your post.
Second, the problem is as you have joined to sources of tables where you have relation ship (exits) prior to Materialize view log, so ORACLE or Optimer getting confused form which rowid's it should give the preference for that.
Either you remove the relations ship and carry out (or) go group Options further to your requirement.
that would solve the Issue.

Refresh FAST for Materialized View failed after Partition Operation

Dear all,
I have created a Materialized View having a simple join between a Dimension and Fact Table of a Datawarehouse. The MV is REFRESH FAST ON DEMAND.
However, when a Partition Maintenance Operation (PMOP) was performed on the Master Tables, the MV failed to Refresh giving a ORA-32313 error.
As suggested on one of the troubleshooting websites, we did a complete refresh of the MV and fixed it temporarily. However, I would like to know the exact cause for this and would like to have a permanent fix for the same.
Can the DBA for this Database provide me the answers or are there some standard troubleshooting steps for the same?
Please let me know.
Best,
Ketan

Hello Maurice,
Here are the answers to your questions.
1) Database is Oracle 9i.
2) We have a stored procedure to refresh the MV. The command is dbms_mview.refresh('SALES_FACT_MV','f'). It was working fine daily. Only after a PMOP was done on the Master Tables, it failed to refresh. We have also created indexes on some columns of the MV for performance improvement. We are getting a very good improvement.
3) We have MV logs for both Master Tables to store the incremental values.
4) We are not able to get the output from DBMS_MVIEW.EXPLAIN_MVIEW since this can be done only by the DBA. WIll update you once I have the info.
5) Same as Point 2.
Let me know if you need any further info.
Thanks, Ketan
