Nologging for a force refresh MV

Hi ,
I am using Oracle 10G
I have created a complex Mv , thus the need for a force refresh and i intend to put this mv into a refresh group
how can i actually get Oracle to truncate the data during the force refresh and
to insert w/o logging ?
i have tried to hide the complext view that uses analytic function into another view but still it complain of it being a complex query
pls advise
tks & rgds

MVs are powerful but aren't as customizable as we would sometimes like. l they function as they will and sometimes variants like the ones you need are difficult to implement if possible at all.
On our project we wanted to use a MV that needed to be completely refreshed daily using SYSDATE to swap effectivity dates in and out but kept current through the day too. SYSDATE prevented the possiblity of a fast refresh. We ended up creating 2 tables of our own (to use one while the other was being refreshed) to implment the functionlity we wanted. You could consider doing something similar.
I hope someone else can give you a more encouraging answer.
Good luck!

  • 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.

    Right now, i have a script scanning the logs for either the 'forced refresh' or the HTTP2228 entries and then remove the object in question but clearly not ideal.

  • Force refresh, only triggers complete refresh PI

    Hello everyone,
    I have a question regarding the usage of the "Force Refresh" option when running mSync (Oracle Lite 10.3.0.1). We have a publication that consists of both complete and fast refresh publication items. Whenever we run a mSync with the "Force Refresh" option enabled, we observe in webtogo that only the complete refresh publication items will be refreshed. Based on the documentation I'm expecting that all publication items should be refreshed. Is this a correct assumption? If so, do I have to make some changes to specific settings to enable synchronization of all publication items, or did I ran into a bug ?
    Thanks in advance
    Patrick

    What do you see in the sync log when doing a force refresh?
    you should see all publication items downloaded with the correct number of records. the complete refresh items should show
    Complete refresh. Cause :: PubItem_mode=complete refresh
    the fast refresh should show CRR
    When you said a user did a rebuild and got the same behaviour, do you mean that the fast refresh publication items were
    a) there with all of thier data
    b) tables there, but no data
    c) not there at all
    if a, then force refresh should work
    if b, then probably an issue with data subsetting or instantiation
    if c, then check c$all_client_items and see if they appear in the list, and check the instantiated flag in data synchronisation>repository>publications>users. If not instantiated, you may not get all of the data
    if there are objects missing from c$all_client_items, try a cut, paste and save on a data subsetting value for the user as that should reset the user

  • Should we use LOGGING or NOLOGGING for table, lob segment, and indexes?

    We have some DML performance issue on cf contention over the tables that also include LOB segments. In this case, should we define LOGGING on tables, lob segments, and/or INDEXES?
    Based on the metalink note < Performance Degradation as a Result of 'enq: CF - contention' [ID 1072417.1]> It looks we need to turn on logging for at least table and lob segment. What about the indexes?
    Thanks!

    >
    These tables that have nologging are likely from the application team. Yes, we need to turn on the logging from nologging for tables and lob segments. What about the indexes?
    >
    Indexes only get modified when the underlying table is modified. When you need recovery you don't want to do things that can interfere with Oracle's ability to perform its normal recovery. For indexes there will never be loss of data that can't be recovered by rebuilding the index.
    But use of NOLOGGING means that NO RECOVERY is possible. For production objects you should ALWAYS use LOGGING. And even for those use cases where use of NOLOGGING is appropriate for a table (loading a large amount of data into a staging table) the indexes are typically dropped (or at least disabled) before the load and then rebuilt afterward. When they are rebuilt NOLOGGING is used during the rebuild. Normal index operations will be logged anyway so for these 'offline' staging tables the setting for the indexes doesn't really matter. Still, as a rule of thumb you only use NOLOGGING during the specific load (for a table) or rebuild (for an index) and then you would ALTER the setting to LOGGING again.
    This is from Tom Kyte in his AskTom blog from over 10 years ago and it still applies today.
    http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:5280714813869
    >
    NO NO NO -- it does not make sense to leave objects in NOLOGGING mode in a production
    instance!!!! it should be used CAREFULLY, and only in close coordination with the guys
    responsible for doing backups -- every non-logged operation performed makes media
    recovery for that segment IMPOSSIBLE until you back it up.
    >
    Use of NOLOGGING is a special-case operation. It is mainly used in Datawarehouse (OLAP systems) data processing during truncate-and-load operations on staging tables. Those are background or even offline operations and the tables are NOT accessible by end users; they are work tables used to prepare the data that will be merged to the production tables.
    1. TRUNCATE a table
    2. load the table with data
    3. process the data in the table
    In those operations the table load is seldom backed up and rarely needs recovery. So use of NOLOGGING enhances the performance of the data load and the data can be recovered, if necessary, from the source it was loaded from to begin with.
    Use of NOLOGGING is rarely, if ever, used for OLTP systems since that data needs to be recovered.

  • Nologging for insert statement

    Hello,
    Is it possible to use NOLOGGING with INSERT statement?
    For example:
    INSERT /*+ APPEND PARALLEL(test,4)*/INTO test NOLOGGING (select .....)
    It will take NOLOGGING as alias name of table or what is correct way to use NOLOGGING for insert statement.

    There is no such thing as a NOLOGGING hint (or insert keyword as you've tried it).
    You must use ALTER TABLE table_name NOLOGGING;

    Hi,
    there are two ways:
    1. near-realtime, which is easier. Use SQL queries to get the information from real time tables from ICM. The information is not really realtime, since it is updated in 5-10 seconds interval.
    2. CTI monitor, which might be challenging. Use the CTI interface of ICM to 'subscribe' for all/selected events, including state changes and then do your calculations. It's realtime, but again, programming it may take a while.

  • How to force refresh of BPM Workspace programatically?

    Hi All,
    As part of our project, we have developed a BPM Workflow with ADF forms based on Human Tasks. Once the form has been processed, the window closes.
    There are 2 issues thatI am hoping for help with.
    1. The worklist is updated only after an explicit refresh is carried out.
    2. I notice that the preview pane in the BPM Workspace still has an active version of the form. The form within this pane is modifiable which poses a business risk in our case.
    My questions are
    1. How do we programmatically force a refresh on the workspace? I'll include this in just after I close the form.
    2. Hide the preview pane?
    Alternately, can all this be achieved by configurations to the Workspace?
    Any suggestions are much appreciated.

  • Safari 5.1.2 is slow, pages need forced refresh

    In the past, I could have a large number of tabs, and Safari worked fine. Recently (I'm not sure how long agao this began), it's gotten slower and slower. Often, when I go back to a tab, it's completely blank. When I try to refresh the page, I get an alert saying that I need to force-reload all of the open tabs. It often takes a very long time.
    Generally, the app runs unacceptably slowly a lot of the time. How can I fix this?

  • Forced refresh of image

    I am using DW8, PHP, mySQL, and IE6 to develop our website.
    After a customer logs in, the following page contains inventory
    records specific to the customer. We want to show their company
    logo on the page as well. Using the process for dynamic images we
    are able to show the logo but .... only it only shows if the F5
    Refresh is pressed within the browser. The link is correct, etc. It
    seems to have something to do with forcing a second read of the
    recordset.
    Is there a function that would resolve the issue. We don't
    expect the customer to 'F5' in order to see the logo. I should
    mention that the previous customer logo is held in the cache so it
    appears on screen until the refresh is done.
    Overall it is driving me slightly off kilter. Any thoughts?

  • Safari doesn't open website fully unless CMD R (force refresh)

    Hello Everyone,
    Headteacher isn't happy that for some reason Safari  will not open images at the top of this website unless I hit CMD R. Doesn't work with the normal refresh/reload button. It works fine in Chrome and Firefox. 
    Site is http://www.lowerpark.cheshire.sch.uk (Using Safari 7.0.1).
    I obviously can't tell all the kids here's a new website but you have to press CMD R if you are using an iMac or MacBook Pro. Normal refresh doesn't work and I can't check if Safari on a PC works as I don't have one.
    Clearing out cache files etc have no effect even using a 'through cleansing' software such as Washing Machine.
    Any advice much appreciated before the headteacher changes to another company to update the school website.

  • How to force refresh of data through browser or PDF?

    We have the dashboard set to refresh every minute.  We are pulling the data using XML from DB.  When we are in browser and clear the browser cache and then reload the .swf... the data is updated.  We haven't been able to figure out how to force the cache-clear and data refresh with either swf or pdf.
    Your help is greatly appreciated.

    Hi Jeff,
    Is the XML coming from a web page or a web server?
    If yes then you can give this a go. To stop the caching mark your web page with extra tags to say it has expired.
    HTML page example:
    <HEAD>
        < META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE" />
        < META HTTP-EQUIV="EXPIRES" CONTENT="0" />
    </HEAD>

      // We do this so that every time Xcelsius calls this page it see the latest results.
