Is it possible to create materialized view log file for force refresh

Is it possible to create materialized view log file for force refresh with join condition.
Say for example:
CREATE MATERIALIZED VIEW VU1
REFRESH FORCE
ON DEMAND
AS
SELECT e.employee_id, d.department_id from emp e and departments d
where e.department_id = d.department_id;
how can we create log file using 2 tables?
Also am copying M.View result to new table. Is it possible to have the same values into the new table once the m.view get refreshed?

You cannot create a record as a materialized view within the Application Designer.
But there is workaround.
Create the record as a table within the Application Designer. Don't build it.
Inside your database, create the materialized with same name and columns as the record created previously.
After that, you'll be able to work on that record as for all other within the Peoplesoft tools.
But keep in mind do never build that object, that'll drop your materialized view and create a table instead.
Same problem exists for partitioned tables, for function based-indexes and some other objects database vendor dependant. Same workaround is used.

Creation of materialized view with view log file for fast refresh in 10.1db

Hi,.. I have a select statements that includes data from almost 20 tables and takes long time to complete..I am planing to create a materialized view on this.. would you please suggest best way of doing this?
we would like to have materialized view and materialized log file to refresh changes from underline table to mv view. please provide help on this .. thanks in advance

It will be possible to create a Materialised view with up to 20 tables, but you have to understand the restrictions on complex Materialised views with regards to fast refresh.

How to CREATE MATERIALIZED VIEW LOG (MV fast refresh) with some JOINS

Hi @ all,
i'm trying to create a MATERIALIZED VIEW LOG for a fast refresh of a MATERIALIZED VIEW.
It works fine with a simple Request in the MATERIALIZED VIEW:
CREATE MATERIALIZED VIEW MV_ZOTD43_P
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT * FROM ZOTD43_P;
COMMIT;
CREATE MATERIALIZED VIEW LOG ON ZOTD43_P
TABLESPACE "GDII"
WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
call DBMS_MVIEW.REFRESH('MV_ZOTD43_P', 'f');
But when I use a complex SQL-Request with some JOINS (one of the Table with spatial Data) in the MATERIALIZED VIEW, I get an error:
CREATE MATERIALIZED VIEW MV_TEST
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT lptd04_p.sst_nr AS sst_nr,
lptd03_p.aaaa AS aaaa,
lptd04_geom.geom as geom
FROM lptd04_p lptd04_p
JOIN lptd01_p lptd01_p ON lptd01_p.cre_nr = lptd04_p.sst_nr
JOIN lptd04_geom ON lptd04_geom.sst_nr = lptd04_p.sst_nr
JOIN lptd03_p lptd03_p ON lptd03_p.lief_nr = lptd04_p.lief_nr;
COMMIT;
CREATE MATERIALIZED VIEW LOG ON LPTD04_P
TABLESPACE "GDII"
WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
call DBMS_MVIEW.REFRESH('MV_TEST', 'f');
Error report:
SQL Error: ORA-12004: REFRESH FAST kann für Materialized View "GDI"."MV_GDI_SST_STAMM" nicht benutzt werden

ORA-06512: in Zeile 1
12004. 00000 - "REFRESH FAST cannot be used for materialized view \"%s\".\"%s\""
*Cause: The materialized view log does not exist or cannot be used. PCT
refresh is also not enabled on the materialized view
*Action: Use just REFRESH, which will reinstantiate the entire table.
If a materialized view log exists and the form of the materialized
view allows the use of a materialized view log or PCT refresh is
possible after a given set of changes, REFRESH FAST will
be available starting the next time the materialized view is
refreshed.
Am I doing something wrong or is it not possible CREATE MATERIALIZED VIEW LOG when the MATERIALIZED VIEW got some JOINS?

Greq

Thanks for the link Alessandro ,
the error seems something to do with the Column-Type SDO_GEOMETRY, so
i create a new thread in the Spatial Discussion forum:

CREATE MATERIALIZED VIEW LOG ON / SNAPSHOT LOG ON

HI,
Is there any difference between create materialized view log on and creat snapshot on.
Did some googling, found out that: A snapshot log is a table associated with
the master table of a snapshot and Is used for refresh the master table\'s snapshots.
Materialized view log is a table associated with the master table of a materialized view. Seem like the same.
By the way, are these tables important? Will my database function as normal without these view log.
regards,
becks

Where did you pick up this syntax from ?
The MV Log that will be created on DOCUMENT will be called MLOG$_DOCUMENT.
So, the correct syntax is :
create materialized view log on DOCUMENT with primary key;this will create a "table" called MLOG$_DOCUMENT which serves as the Materialized View Log on the real table called DOCUMENT. This will allow you to create one or more Materialized Views based on DOCUMENT, which can be fast refreshed because of the presence of the MV Log. For example :
create materialized view MV_DOCUMENT refresh fast on demand as select DOC_ID, DOC_DATE from DOCUMENT;(i.e. assuming you want an MV that has only two columns from the table DOCUMENT.

How to create materialized view log on remote database

How do you create materialized view logs on a remote database.
I tried
create materialized view log on global_express_views.vccs438_project_work_request@h92edwp with sequence, rowid ( columns...)
ERROR at line 1:
ora-00949 illegal reference to remote database

Hi,
I am not getting the error exactly. But have some suggestion:
If the schema owner does not own the master tables, then the schema owner must have the GLOBAL QUERY REWRITE privilege or the QUERY REWRITE object privilege on each table outside the schema.
Hope, this may help you?
Thanx.. Ratan

Materialized View with Join for FAST Refresh

Hi Gurus,
Facing issues in MV with a simple join for FAST Refresh.
2 sample Tables:
1. employee
empid integer PK
empname varchar(50)
deptid integer FK
2. delta_employee
empid integer PK
empname varchar(50)
deptid integer FK
dmlflag varchar(2)
watermark integer
Code is as given below -
CREATE MATERIALIZED VIEW LOG ON work.employee
WITH SEQUENCE,rowid(empid)
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON work.delta_employee
WITH SEQUENCE,rowid(empid)
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW work.MVEmployee REFRESH force on
demand with rowid AS
select e.empid,e.empname,e.deptid,d.empid t1
from work.employee e, work.delta_employee d
where e.empid = d.empid;
Able to perform Complete Refresh. Not able to use Fast Refresh for
incremental refresh.
Please help.
Thanks,
J Kumar

Found a solution,
As per oracle documentation rowid fileds should be included in the Select statement. Even though I included the rowid fields, empid in this case it still didnt work.
The implementation of the rowid column should be included with tablename.rowid instead of the tablename.columnname !
Modified script is as given below.
CREATE MATERIALIZED VIEW WORK.MVEMPLOYEE
REFRESH FORCE ON DEMAND
WITH PRIMARY KEY
AS
select e.rowid "empid",d.rowid "t1" ,e.empname,e.deptid
from work.employee e, work.delta_employee d
where e.empid = d.empid;
And It really WORKS

Can I create index on Materialized view log

Hello
The ADDM suggest me to create index on some fields of my materialized view log , I don't know does it cause any problem ? Is it safe ? have you done it before ?
thanks

Actually you can do it since materialized view log is in fact a table.
SQL> create table t(x int primary key);
Table created.
SQL> create materialized view log on t;
Materialized view log created.
SQL> select segment_name, segment_type from user_segments;
SEGMENT_NAME
SEGMENT_TYPE
MLOG$_T
TABLE
T
TABLE
SYS_C004857
INDEX
SQL> desc mlog$_t;
Name                                      Null?    Type
X                                                  NUMBER
SNAPTIME$$                                         DATE
DMLTYPE$$                                          VARCHAR2(1)
OLD_NEW$$                                          VARCHAR2(1)
CHANGE_VECTOR$$                                    RAW(255)
SQL> create index i on mlog$_t(x);
Index created.However I don't know if this is really supported and makes sense.

Whats the purpose of materialized view log?whats create view log with rowi

Why we create materialized view log ?????whats the use???
what do you mean by "create view log with rowid"
Regards
Gagan

A materialized view log stores the change vectors made to a particular table in order to allow materialized views that reference that table to be incrementally refreshed rather than re-materializing the data every time. It's a much more efficient way to refresh a materialized view.
WITH ROWID specifies that the materialized view log should store the ROWID of a row with the change vector, which is one way of identifying which row(s) in the materialized view should be updated by which change vector. You can also use the primary key value for this.

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
Voranc

And, I'm using Oracle 10g.

Materialized view log and user....

Hi,
Assume that a user , let's call him A owns a table and another user B needs to create a materialized view log on the table who owns the A user.
Whereas the user B do have all object privileges(direct priv insert, update, delete.. not via a role) on the table of user A he cannot create a mv log on this table on his schema....
So, the stmts insert/update/delete on <tab_name> are successfully executed (having connected as user B).
The error message "ORA-00942: table or view does not exist " appears when i issue the command:
connect B/B;
create materialized view log on tab_name with sequence including new values;
Note: I use ORADB 10.2.0.4 and there is a synonym of tab_name to the user B (who tries to create the mv log on)...
Is the above req. possible in any way...???
Thank you,
Sim

The documentation says the following:
The materialized view log is created in the same schema as the target master.HTH!

Materialized view (fast refresh mode) + Materialized view log on another DB

Hi all,
I created a materizalied view using this script :
CREATE MATERIALIZED VIEW GIPS.DOSSIER_MEDICAL_MV2
TABLESPACE GIPS_T
NOCACHE
NOLOGGING
NOCOMPRESS
NOPARALLEL
BUILD IMMEDIATE
USING INDEX
TABLESPACE GIPS_I
+ REFRESH FAST ON DEMAND +
START WITH TO_DATE('11-janv.-2011 16:00:00','dd-mon-yyyy hh24:mi:ss')
NEXT sysdate (1/96)+
AS
SELECT N0_SEQ_BLOB_PDF,
EXAM_ID,

MEP,
MSJ,
TTD,
exam_type
FROM DOSSIER_MEDICAL@dbdoc_lk
WHERE DOSSIER_MEDICAL.EXAM_TYPE IN ('TELEM', 'SCANNER', 'EPPO_SECMED');
So you can see I'm using a dblink in the select statement ( DBDOC_LK )
On the DB referenced by this dblink, I created a materialized view log using this script :
CREATE MATERIALIZED VIEW LOG ON "DOSMED"."DOSSIER_MEDICAL"
TABLESPACE "DOC_T"
WITH PRIMARY KEY
INCLUDING NEW VALUES;
The problem is that my materialized view has never refreshed since its creation ! and I don't understand why ?
Can someone help me ?
Thank you.

The REFRESH schedule causes a job to be created for the execution of the Refresh. You should see this job in DBA_JOBS / USER_JOBS.
The job would run only if the instance parameter JOB_QUEUE_PROCESSES is set to 1 or higher (the default is 0). This parameter can be modified dynamically with an ALTER SYSTEM command.
