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.

  • 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.

  • 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

  • Materialized View with No Logging Option;;; THX

    Hi all,
    What's the diffrence between a :
    Materialized View with No Logging Option
    Materialized View with Logging Option
    thank you

    LOGGING|NOLOGGING specifies that subsequent Direct Loader (SQL*Loader) and direct-load INSERT operations against a nonpartitioned index, a range or hash index partition, or all partitions or subpartitions of a composite-partitioned index will be logged (LOGGING) or not logged (NOLOGGING) in the redo log file.
    In NOLOGGING mode, data is modified with minimal logging (to mark new extents invalid and to record dictionary changes). When applied during media recovery, the extent invalidation records mark a range of blocks as logically corrupt, because the redo data is not logged. Therefore, if you cannot afford to lose this index, you must take a backup after the operation in NOLOGGING mode.
    If the database is run in ARCHIVELOG mode, media recovery from a backup taken before an operation in LOGGING mode will re-create the index. However, media recovery from a backup taken before an operation in NOLOGGING mode will not re-create the index.
    An index segment can have logging attributes different from those of the base table and different from those of other index segments for the same base table.

  • Creation of Material from SAP VIEW using CDESK.

    Hi  Experts,
    I have one question related to creation of Material from SAP View.
    CAD file created say SM1000.prt
    Create DIR in CAD View say SM1000
    Scenario 1 :   Create Material in Background from CAD VIEW or SAP VIEW from cad desktop, It creates material SM1000
                               in background.
    Scenario 2 : Open CDESK ( Transaction)
                            Click on OPEN,
                            Selecting the DIR created SM1000
                            Create the material in background in SAP View, it gives message " enter material number"
    Why am not able to create the material from SAP view using CAD Desktop. If any modifications needs to be done in CDESK CUS to solve this please let me know.
    Thanks,
    Sudharshan

    Hi Sudharshan,
    maybe the reason for this is that your CAD applications provides a special material number and the customizing in CDESK is defined to use this number. In this case the number or value can by provided from the CAD application only from the CAD View.
    In the SAP view the material gets created like in MM01 for example and so mabye you have to enter a material number.
    Best regards,
    Christoph

  • Materialized view logs for Fast refreshes

    Hi,
    I created MV and MV logs on the base table/main table. I set the base table in NOLOGGING MODE. so ofcourse redo is not gonna generate during DML but i wanted to know that:
    Will NOLOGGING effect the MV logs for fast refreshes?
    I came up on conclusion that MV logs are nothing to do with Redo Logs and would have no impact on MV logs for fast refresh since i have set my all base table in NOLOGGING MODE.
    Looking forward for expert opinion.
    REGARDS,

    Though I'm not an expert...

    I thought it may be related to spaces in the path in which the script was called from. I tried having the ODBC command script in another directory but the same thing happens. It will give me the "CONFIGSYSDSN: Unable to create a data source for the 'Oracle in OraClient10g_home1' driver: Could not load the setup or translator library with error code -2147467259". As soon as the script is done running I can manually double click the script and it adds the DSN fine.

  • Warnings in the Upgrade Log file for OBIEE 11G from 10G

    Hi,
    I am new to OBI 11g.
    I have installed simple type OBI 11g (version - 11.1.1.5.0) on a single server(Windows 2003, RAM-4GB,CPU-2.8GHz Dual Core ). I used upgrade assistant to upgrade the RPD & Webcat from 10.1.3.4.1 version to 11g, but I got about 50K warnings in the upgarde log file for the web catalog. They were basically 2 types as below -
    1. [2012-02-24T13:17:48.255-05:00] [BIEE] [WARNING] [] [upgrade.BIEE] [tid: 14] [ecid: 0000JMk1k3lDkZKcyToYpk1FHuer000005,0] Invalid columnID reference 'c10' in views!
    Does someone know this warning and if this requires a fix or it would not impact any reports or dashboards? This error is about 25K times in the upgrade log file.
    2. [2012-02-24T12:20:04.162-05:00] [BIEE] [WARNING] [] [upgrade.BIEE] [tid: 14] [ecid: 0000JMk1k3lDkZKcyToYpk1FHuer000005,0] Removed the following node from the element 'view': [[

    I have checked this error on Oracle support web and it says that this warning is fine as there have been some features in 10G that would not be in the OBI 11G and are not required. I am still not convinced why there should be any warning for this type of issue.
    Please let me know if someone has faced these warnings in when doing the upgrade of the 10g RPD and Webcat to 11g together.
    Just as note, the services start fine and I could login to the application with users and see the dashboards and reports although I did not check all the dashboards and reports as this is a POC before doing the actual upgrade.
    Edited by: user11255710 on Feb 24, 2012 1:44 PM

    Hi
    Can you please refer me to the links on oracle web support which explained that these warnings are ok and can be ignored. We are also facing the same issue.
    Thanks in advance.

  • Bizzare error message requests me "Select a log file" for .vi

    Hi
    I am getting a very strange pop-up with my vi that requests me to select a log file for the VI.
    If I hit cancel I get the pop-up "Cannot log front panel of vi. there is no log file associated with the vi"
    I don't want a log file. 
    There must be some background setting in the VI that is not in the actually Lab-VIEW code.
    Does anybody know how I can switch this off?
    Many thanks
    Ashley

    Off the top of my head I can only think of one setting that may cause this.  You can set a VI to log its front panel data automatically.  Go to Operate>>Data Logging and check the settings there.    Also look at Operate>>Log at Completion.
    It may also be that you have this set on a subVI, and if so you will see a yellow "halo" around one of your subVIs, meaning you have turned on database access.  You can look in the help for Logging Data>> On the front panel that discusses this behavior.
    If you wrote the VIs and have no idea what I am talking about with the Database Access that is fine, it is not a commonly used feature.
    If none of these help can you attach the VI so we can all see it.

    I have completely uninstalled the HRC, and download from server install again -- still doesn't work with exactly same error.
    this matter only happens on this PC, when user try same thing on other PC, it works.

    What is the OS version of the PC you are running  and is it physical machine or virtual machine that is running the HRC client ..
    OS Version Windows 7 Home Premium  64 bit and it’s a physical machine.
    . The Max DB Connections for Report Client Sessions is set to 5 for each servers (There are two servers). The no of HR Sessions is set to 10.
    I wanted to know if there is a way to find the HRC sessions active now and terminate the one or more or all of that sessions from the server end ? 

    We have had this "PRX5" problem with Exchange 2013 since the RTM version.  We recently applied CU3, and it did not correct the problem.  We have seen this problem on every Exchange 2013 we manage.  They are all installations where all roles
    are installed on the same Windows server, and in our case, they are all Windows virtual machines using Windows 2012 Hyper-V.
    We have tried all the "this fixed it for me" solutions regarding DNS, network cards, host file entries and so forth.  None of those "solutions" made any difference whatsoever.  The occurrence of the temporary error PRX5 seems totally random. 
    About 2 out of 20 incoming mail test by Microsoft Connectivity Analyzer fail with this PRX5 error.
    Most people don't ever notice the issue because remote mail servers retry the connection later.  However, telephone voice mail systems that forward voice message files to email, or other such applications such as your scanner, often don't retry and
    simply fail.  Our phone system actually disables all further attempts to send voice mail to a particular user if the PRX5 error is returned when the email is sent by the phone system.
    Is Microsoft totally oblivious to this problem?
    PRX5 is a serious issue that needs an Exchange team resolution, or at least an acknowledgement that the problem actually does exist and has negative consequences for proper mail flow.
