• Cannot create Materialized View using the PL/SQL procedure

  Hello
  
  I have a question related to the creation of materialized view.
  I have a stored procedure that creates the materialized view. When you try to perform this procedure, I get not enough privileges error: ORA-01031.
  
  When I run the content of this procedure as a PL/SQL block anonymous their materialized view is created without any complications.
  Can you please advice me on this subject?
  It is even possible to create a materialized view in the stored procedure as I found no info on this subject.
  
  Thank you

  Hi chudapet,

  Whenever you make in procedure, you must have direct subsidies and not through a role.

  Most likely the grant to create a materialized view is available via a role to your username.
  Assign a direct grant to the user:

  grant create materialized view to scott;
  {code}                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
  

• Fine views of the site in FF and not in IE (or Chrome)

  Maybe you can see something that is beyond me. My new dog lying to overhaul current http://lyingdognews.net, created in DW CS3 (using the model 'thrColLiqHdr') on a PC, works great in FF 3.0.3 but in Internet Explorer (7.0) and display in Google Chrome (0.2.149.30) are not pages. The home page displays well in IE and Chrome, but when you click on one of the links on the home page, the page loads, but only the background screens. Interestingly, the only exception on the home page is the link in the menu bar, labeled "NDA Feeds, Etc. That, for some reason, works very well.
  
  A suspicion that I had was that I had initially agreed with a seller of ad (AdBrite) to have ads full page on the site, but I cancelled them because they were too disruptive. Maybe the changes have not taken effect? But then why not FF fine with pages and the IE and Chrome? Etc.
  
  Thank you for all you can shed some light.

  Thank you, Nancy. I should have posted things first.

• Constraints foreign key in materialized views can be changed (approx 1-master)

  I have a system which consists of a master database and a bunch of materialized view sites homogeneous. 10.2.0.4 all around. Main server is Windows Server 2003. all remote nodes are Windows XP. All materialized views are editable. There are only 20 or two tables (materialized views). Users enter data in the system at the level of the remote nodes via an application.
  
  There are data integrity constraints in the database on the main site. In the hunt for replication errors, I discovered that the integrity constraints do not exist in the context of the remote node. Then, sometimes, that users can enter data not valid that main site integrity constraints disallow, producing errors of replication on the master site. For a test I then implemented manually some of the constraints on a remote node using the java Enterprise Manager UI. Constraints have behaved as expected, as far as I can tell.
  
  My ultimate goal is to implement, on all sites of the materialized view, the current constraints of the integrity of the main site, so that entering data at remote sites is governed by the integrity constraints.
  
  I looked briefly package DBMS_REPCAT subprograms. Nothing jumped out at me.
  
  I started to collect the DDL (ALTER TABLE... ADD CONSTRAINT...) I could run each site through SQL * more sheet calculation.
  
  Then I thought that maybe I could use sqldeveloper to run the DDL but when I open the relevant schema to the level of the remote nodes, the actual tables are not shown, only the USLOG$ _... things. Materialized views are shown - but they do not have a constraints tab.
  
  After some time in the manuals, I decided that I have a good knowledge of what I see; and that's why I'm not sure I'm running in the right direction.
  
  I will summarize two questions:
  
  (1) what is the best way for me to apply constraints of integrity of the master site existing in materialized views can be changed on all nodes?
  
  (2) why I can see and work on the tables on the remote nodes via the EM java, but don't can't see them via sqldeveloper, logged in with the same account twice?
  
  P.S. It is possible for me to delete and re-create all databases and the views materialized on all remote nodes. It is not a high volume system, and there are windows of time during which I can do these things if necessary. I don't expect a structural change to the database, so I don't need to be able to spread future changes, just make things sync'd up now.

  Hi Clark,.
  you are right THAT FK on mviews can cause many problems during refresh. I mentioned on delete cascade, but delete the null value or remove restricted can cause problem too. You cannot complete with active reftesh FK referencing MV PK.

  Because you cannot control the mviews refresh a refresh Group, that the problems I described before can occur.
  You have to my view of these possibilities:
  1 / move Ref. integrity check from the DB to the logic of the application
  2 / use triggers to maintain ref.integrity check DB
  3 / mutlimaster user instead of mviews replication

  But none of them have their more and less.
  1 / + FK is checked - take some time, any other manipulation of data through the application can break rules FK
  2 / + FK is cheked on DB level - you write triggers, lower performance, changing disorders tables
  3 / + FK is chedked at the DB level, - all the data is replicated on the table plan (for MV, you can define where cluase for replication mutlimaster not), with more than two masters, it is difficult to define the replication conflict resolition method that convert in the last time.

  Last post:
  I my case I use this "thing":
  Because our request has not been managed in environment 24 x 7 I wrote my own routine to refresh.
  This routine that follows:
  1 / disable necessary FK
  2 / call dbms_refresh.refresh to perform the refresh of the refresh Group
  3 / activate FK disabled in step 1 with the novalidate
  Refresh the jobs was launched at night.

  Hello

  I learned and referred website as much as we can not able to create a trigger in MView (sorry we create trigger but none use of creation because in view no insert and update happened). So I drop completely the materialized view concepts and relaxation.

  This discussion will be useful for any future reference.

• How to stop refreshing materialized views if the source table is null

  any ideas?

  Probably not what you were hoping for, but here's a few ideas.

  Your account shows - 113 (85 pending)
  1. How about helping to keep the forum clean by examining your 85 not resolved previous issues and give credit relatively USEFUL or RESPONDED to those who helped you in the past.

  2. read the FAQ at the top right of the page and view information about your system and your software so that we know what you're working with.

  3 ask your question in the body of the thread. Don't tell "of ideas.

  What is your question? Is this an academic question or you have a real problem that needs to be addressed?

  If you have a problem producing the DDL for the materialized view, and information about the type of discount that has been set up for this. Is there a newspaper view materialized on the underlying tables?

  The simple answer to your quest is to use UPDATE them on REQUEST and check the base tables before making a manual
  a: the best answer depends on what version of Oracle you are using and what is your actual configuration. Are your
  MVs in REFRESH GROUPS? Who can make a difference in the response.

• Moving all the newspapers and Materialized View at the schema level using the data pump in

  Hi Experts,
  
  Please help me on how I can exp/imp all materialized views andMV logs (as are some MVs) only the full scheme of other databases. I want to exclude everything else.
  
  Concerning
  -Samar-

  Using DBMS_METADATA. Create the following SQL script:

  SET FEEDBACK OFF
  SET SERVEROUTPUT ON FORMAT WORD_WRAPPED
  SET TERMOUT OFF
  SPOOL C:\TEMP\MVIEW.SQL
  DECLARE
      CURSOR V_MLOG_CUR
        IS
          SELECT  DBMS_METADATA.GET_DDL('MATERIALIZED_VIEW_LOG',LOG_TABLE) DDL
            FROM  USER_MVIEW_LOGS;
      CURSOR V_MVIEW_CUR
        IS
          SELECT  DBMS_METADATA.GET_DDL('MATERIALIZED_VIEW',MVIEW_NAME) DDL
            FROM  USER_MVIEWS;
  BEGIN
      DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR',TRUE);
      FOR V_REC IN V_MLOG_CUR LOOP
        DBMS_OUTPUT.PUT_LINE(V_REC.DDL);
      END LOOP;
      FOR V_REC IN V_MVIEW_CUR LOOP
        DBMS_OUTPUT.PUT_LINE(V_REC.DDL);
      END LOOP;
  END;
  /
  SPOOL OFF
  

  In my case the script is saved as C:\TEMP\MVIEW_GEN. SQL. Now I will create a journal mview and mview in schema SCOTT and run the script above:

  SQL> CREATE MATERIALIZED VIEW LOG ON EMP
    2  /
  
  Materialized view log created.
  
  SQL> CREATE MATERIALIZED VIEW EMP_MV
    2  AS SELECT * FROM EMP
    3  /
  
  Materialized view created.
  
  SQL> @C:\TEMP\MVIEW_GEN
  SQL> 
  

  Run the C:\TEMP\MVIEW_GEN script. SQL generated a C:\TEMP\MVIEW queue. SQL:

    CREATE MATERIALIZED VIEW LOG ON "SCOTT"."EMP"
   PCTFREE 10 PCTUSED 30 INITRANS
  1 MAXTRANS 255 LOGGING

  "COMM","EMP"."DEPTNO" "DEPTNO" FROM "EMP" "EMP";
                                 
  

  Now, you can run this on the database. You may need to adjust the tablespace and storage clauses. Or you can add more DBMS_METADATA. SET_TRANSFORM_PARAM calls to C:\TEMP\MVIEW_GEN. SQL to force DBMS_METADATA not to include the tablespace or / and the terms of storage.

• Migrate the site and master passwords and logins for Firefox to light

  To expedite my USB mobile browser, I want Firefox v.30 a light v.30.
  Only now I noticed I still signons3.txt instead of key4.db and cert8.db instead of cert9.db in the Firefox profile.
  https://support.Mozilla.org/en-us/KB/recovering%20important%20data%20from%20an%20old%20Profile#w_your-important-data-and-their-files Specifies not how to upgrade these versions, or some other answers, for example https://support.mozilla.org/en-US/questions/767061.

  Copy of signons3.txt, signons.sqlite between profiles has not helped get my password or my master password in light.
  Any thoughts why? Because I signons3.txt instead of key4.db, or because I use the master password?

  Note that you can use a CMD or BAT file to set an environment variable temporarily for this start.

  Set NSS_DEFAULT_DB_TYPE = sql
  Start "" "path to Firefox\firefox.exe" PEI

  I noticed that SQLite files are much larger, because likely Firefox uses a minimum size to avoid problems with fragmentation as is done with all files in SQLite.

  Note that Firefox is actually declining many SQLite files and replace them with the files of JSON type (extensions.json, addons.json, search.json, logins.json) to avoid the problems that SQLite gives in some cases and make it easier to keep the database in memory to boost performance.

• question on the materialized view unregistered on the main site

  Hello
  
  you know how one knows, on the main site, on the existence of a materialized view another site referring to other tables to a primary site. It seems registration is not required.
  
  the site main orcl1: I have a table, and a materialized view log defined on A table.
  another site orcl2: have a link db orcl1 and rapid updatable view SCOTT materialized. A_MVW (create a materialized view A_MVW cool off quickly in select * from A@orcl1)
  
  on orcl1 I perform: exec DBMS_MVIEW. UNREGISTER_MVIEW (mviewowner = > 'SCOTT', mviewname = > mviewsite, 'A_MVW' = > 'ORCL2');
  so the materialized view seems to be correctly set aside (because it no longer appears in: select * from DBA_REGISTERED_MVIEWS ;))
  But, to my surprise, I can still perform refreshes fast on A_MVW, which also remove rows from the materialized view log. So how is site orcl1 always aware of the existence of the materialized view?
  
  It seems that, registered or not to the main site, a materialized view has the same... or is not? where is it stored, on the main site, information about materialized views (especially those of quickly updatable) as local tables reffer?
  
  Thank you

  You should have added the Master_RepObject and call Generate_Replication_Support between the INTERRUPTION / RESUMPTION.
  The actual creation could be pushed through the DBMS_DEFER_SYS.

  You have tasks running in the background? You asked DBA_REPCATALOG to see if the request for creation of the index was pushed and executed?

  (BTW: I did it for the MultiMaster replication.) Not sure if index on MVs are treated in the same way or not really need to be created manually).

  Connect B/B;
  create log view materialized on table_name with sequence including new values;
  
  Note: I use ORADB 10.2.0.4 and it stands for table-name to user B (which tries to create the log of mv on)...
  
  The req. above is possible somehow?
  
  Thank you

  The documentation says the following:

  The materialized view log is created in the same schema as the master of the target.

  HTH!

• Re: view opaque and the materialized view

  Hi Experts,

  I want some clarification of opaque and view view in the physical layer OBIEE materialized

  -> what is the main difference between the opaque view and materialized in the RPD perspective view, we have to do this at the level of the RPD or DB.

  -> I want the list of opaque opinion and materialized in the RPD view how I should do.

  -> How opaque views will degrade the performance and how a materialized view will improve performance at the level of the report.

  -> In scenarios that we use view opaque and the view materialized (if possible with a scenario for the best permanent basis).

  Thanks in advance.

  Opaque views is a SQL statement that is defined in the physical layer, OBIEE will use all in the construction of a SQL query. In a way it's not different from a database view, except it is set in OBIEE only. Alternatively, you can deploy an Opaque view, which pushes its definition in the database. Read more about it here: work with physical tables, Cubes and joins - 11 g Release 1 (11.1.1)

  A materialized view (MV) is a database concept where the results of a SQL statement are physicalised like a table, and therefore as OBIEE is a MV is just another physical array

  -> If I want a list of the opaque views and materialized in the RPD view how I should do.

  To find opaque views, use the function «Repository of applications» administration tool Search physical Tables and set up a filter on the Type = Select

  To find materialized views, you will need to query the catalog in your database (for example select object_name, object_type from user_objects where type_objet = "MATERIALIZED VIEW" ;) and compare it to the list of tables in your SPR)

  -> How opaque views will degrade the performance and how a materialized view will improve performance at the level of the report.

  A materialized view is materialized, in other words, the results are already stored in the database. This means usually there will be more efficient because all the joins and aggregations, etc. will be settled in advance.
