Refresh Time to be reduced in 11G

Hi Experts,
Kindly provide your suggestions,
We have a scenario where the reporting database is refreshed on a daily basis from the production.
the apps team has requested us to do this activity post EOD backup.
Please suggest the fastest method to execute the refresh.
Currently it takes the 6 hrs for refreshing.
DB version : 11.2.0.1
AIX : 6.1
Regards,
Ch

We have not done any DG or Clone of that.However, it could be a very good way to reduce time. A standby database could be opened during working hours, then restored and production archivelog files applied afterward. Or since you are on 11gR2, you could use snapshot database. It is well explained in documentation :
http://download.oracle.com/docs/cd/E11882_01/server.112/e17023/cli.htm#DGBKR3432
Any sugestions furthur. You did not say anything on how you are "refreshing" your database, neither if the database is close to the source.

    I have created indexes on BILLING_ACCOUNT_ID and BLG_SYS_CUST_ID.
    There are 4.3 million records in the snapshot.
    It takes 6hrs to refresh the snapshot.
    The questions I have are:
    1. How can I reduce the refresh time? Is it because of the indexes? Should i make any change to the create snapshot script?
    2. The create snaphot query works fine without the rownum < 500000 statement in oracle 9i but in oracle 8i it gives
    CSBAN10V user not found in UCDWP001 error. It works OK with the rownum < 5000000 statement. Why is that so?
    thanks
    prash

    You are specifying that the refresh must be COMPLETE, so Oracle has to transfer all 5,000,000 rows over the wire from the remote database every time. If you specified that the refresh could be FAST, and created a materialized view log on the remote table, Oracle would be able to transfer only the changed rows each time you refreshed.

  • Input Form/Reports Refresh time

    Hi all,
    We have input form/reports which takes about 45 seconds to refresh which is ok for the first time but the frustration from the user community is that every subsequent refresh also takes 45 seconds for even a small change. Is that possible to reduce time on the subsequent refresh time?
    Please share.
    Thanks,
    D

    Hi Devang,
    Refresh means that all data on the form have to be read from database. You can play with user settings: Refresh only Expanded and Inserted Members; Refresh only Data on "Save & Refresh Data", but not sure it will help.
    In general, the initial refresh for 45 seconds is a bit long. Do you have not default measures and dimension member formulas in the report?

  • Time Capsule slow as 802.11g WAP

    I've been having trouble with my wireless network since I received my 1TB Time Capsule. AppleTV quit syncing, .Mac Sync hung repeatedly, and Printing via the Time Capsule stutters. I only have 802.11g hosts on my network, so 802.11n performance isn't something I'm evaluating.
    The goal of this testing is to assess the Time Capsule as a network access point for 802.11g hosts. Disk read/write is not part of this experiment. Each of the measurements below are results from the exact same test -- measure internet upload and download performance to a test server on the speedtest.net network.
    My topology is as follows:
    SBC DSL -> 2Wire modem -> TimeCapsule
    For the tests below, I connected my MacBook Pro to each device, wirelessly via 802.11g and direct connect via Ethernet and ran the test from speedtest.net. Since I have a 3Mb connection, the speed of my ethernet is irrelevant. The results of the testing is below and the results show that using the Time Capsule as an 802.11g hub is slow, in fact 75% slower.
    Internet Performance (3Mb service)
    network performance -- connecting via
    *660k dl/430 ul -- TimeCapsule (802.11g - single base station, or as WDS main)*
    2546k dl/429 ul -- TimeCapsule (Ethernet Hard Wired)
    2547 dl/432 ul -- 2Wire 802.11g
    2546 dl/431 ul -- 2Wire (Ethernet Hard Wired)
    My conclusion, based on this testing and from several posts in this discussion board is that the Time Capsule exhibits poor performance for hosts connecting via 802.11g.
    Is there some setup thing I'm missing?

    The initial backup should have been wired. Future incremental backups would not be this large and wireless backups should be okay.

  • Changing default refresh time for the UWL.

    Hello,
    I am trying to change the Default refresh time for the UWL(workflow inbox) for all the users before they personalize or save the refresh time, Would changing the refresh time in the .xml file work or is there any other way to do it? Thanks,
    Aniketh R.

    We have had all sorts of issues with this as well. I have been unable to find a solution that works as of yet. From my own debugging it seems as if RP is trying to parse the pasted text as logo's, fields etc.... I am looking at potentially using a script w/ set interval to "clean" the clipboard data but this isn't a perfect solution for numerous reasons.
    What is happening to your letters when the users paste? Our letters actually become unusable after a plugin save. So I am actually very interested in the answer to this question!

  • Device Default Refresh Time

    I was wondering what the default refresh time is for ZCM 11.2.4 MU 1?
    Is there a recommended time that we should be setting this too?
    Currently we are set at 2 hours, for a partial refresh, and 12 hours for a full refresh.
    Has anyone seen/recommend that those settings should/could be adjusted to allow for faster refreshes?
    Thanks,
    -DS

    That will "Slow Down" the refresh rate, but may speed logon times.
    Unchecked, means it would check immediately and not delay to speed logons.
    The Default delay is 5-6 minutes.
    If you want new assignments to appear more quickly throughout the day,
    you need to lower the partial and/or full refresh.
    Partial Excludes Bundles but is everything else.
    Full is everything.
    Since Bundles may be want most interests some customers, I have seen
    some have just turned off Partial and only do full at an increased
    frequency.
    Monitoring performance is important as you decrease the interval.

  • How to find total refresh time of Materialize view?

    Hello All,
    I want to know the total refresh time of Materialize view. i m refreshing MV by below statement
    i hv not logging the start and end time of this in process.
    exec dbms_mview.refresh('EMP_MV','C','',FALSE,FALSE,0,0,0,TRUE);
    So, anybody can you please know the using which database table it cab be possible?
    Thanks in advance

    The only way you can log the refresh time for each execution is to wrap the call inside a procedure that also logs the start and end times to a logging table.
    (if you manually run the exec dbms_mview.refresh from an SQLPlus command line, you could also SET TIMING ON in SQLPlus)

  • How do I speed up the email refresh time on my Mac ? iPad and IPhone almost a minute or more faster using same connection?

    How do I speed up the email refresh time on my MAC?

    Hi ToddSATX, 
    Thank you for contributing to the Apple Support Communities. 
    It sounds like you receive email a few minutes faster on your iOS devices than on your Mac. This may be normal behavior, although there are a few settings that you can check if the delay is longer than that. 
    If you have a portable Mac, you may notice an improvement when it is connected to the power adapter. You can also select "Use IDLE command if the server supports it" from Preferences > Accounts > Advanced in the Mail menu (at the top left of the screen).
    You can find this information here:
    Mail (Yosemite): General preferences
    Check for new messages
    When Mail gets new messages from the mail server. By default, the option is set to Automatically (Mail varies how often it gets messages, based on whether your Mac is plugged into an electrical outlet). 
    An IMAP account may get messages more frequently if the mail server supports the IDLE command; make sure the option to use it is selected in the account’s Advanced pane in Mail preferences. 
    If you set the option to Manually, click the Get Mail button  in the Mail toolbar to check for messages. (Whenever you click an IMAP or Exchange mailbox, it syncs with the server, and shows new messages.)
    Best Regards,
    Jeremy 

  • Observing mutiple computers lower page delay or refresh time??

    I am trying to use ARD 3 to monitor couple computers.
    But the default refresh rate a real time and taking up too much bandwidth.
    I wanted to observe those computer with an update rate of every 15 minutes.
    Is this possible?
    The problem is the Page delay is grey out under view options.

    The delay does not represent the refresh time. The delay represents the amout of time to stay on a particular page before rotating to the next page.
    To make the slider active, simply decrease the number of computers visible on one page.
    ARD is in constant contact with the machines you are monitoring. There is no way to only update every 15 minutes.

  • How to tell mview refresh time including minutes

    Hi,
    Using usr_mviews, I can get last_refresh_date. But it didn't tell hour and minutes. Is there a method I can get last refresh time including hour and minute?
    Thank a lot,

    I would use
    alter session set nls_date_format = 'dd.mon.yyyy hh24:mi:ss';
    then you don't need to change your query.

  • Why in ospf , lsa refresh time is set as 30 minutes

    Hi all
    i have doubt regarding the ospf lsa refresh time interval . why this is set as default by 30 minutes . is there any particular reason for this ? Please let me know

    Hi,
    RFC 2328 stipulates two facts:
    The maximum age of an LSA is 3600 seconds. After an LSA has reached an age of 3600 seconds, it must be flushed.
    Every LSA has to be reoriginated (that is, refreshed) every 1800 seconds.
    The choice of 1800 seconds for the refresh interval is purely a very conservative estimate of the advance in which an LSA should be refreshed so that it can still be propagated to all other routers in an area or OSPF domain in time before the old LSA expires by reaching the age of 3600 seconds. In essence, the choice of the refresh interval at 30 minutes gives the network an additional 30 minutes to propagate the refreshed LSA before the old one expires.
    In fact, current Cisco IOSes do not go by the exact 1800 second interval. The IOS has chosen various approaches to scheduling the LSA refreshing process, and it is very nicely described in this article by Petr Lapukhov:
    http://blog.ine.com/2009/12/31/tuning-ospf-performance/
    Scroll down to the part called LSA Group Pacing.
    Best regards,
    Peter

  • Web report for opening it takes long time how to reduce the time?

    HI Experts,
    I created report using webi. For next time while opening it takes more time. How to reduce the time.

    Hi Manikandan,
    There could be multiple reason behind the bad performance.
    1. Are you using supported JVM version to run Webi reports?
    2. Do the reports contain prompts? Are the LOVs set to "Automatic refresh before use"? If yes, uncheck it.
    3. How many queries do the report has? Can you run the queries one by one and check which query is taking much time?
    4. If it based on relational database, copy and run it against the database directly and check how much time it takes. If more, you may have to fix the issue at database level like using temporary tables, indices, etc.
    5. Also check if there are firewalls or proxy server between client and server communication. if yes, try to refresh the report directly on BO server and check.
    6. Check if there is any hinderance between BO server and Database server communcation.
    Hope it will help.

  • ETL execution time want to reduce

    Hi Everybody,
    I am working on owb 10g with R2.
    Environment is win 2003 server 64bit itanium server,
    oracle 10 database in netap server mapped as I drive on 186 server where owb installed.
    source files : oracle's staging schema
    target : oracle target schema
    Problem :
    The problem is before 1 month our ETL process was taking 2 hrs to complete .
    now a days 5 hrs...i dont know why.
    any body suggest what I need to check in owb.
    for optimization.

    Thanks for reply sir,
    as you suggest a query for checking the execution time in desc order, I am sending you little bit o/p for today date execution.

    ==================================
    I think Elapse time depend on No of rec selected and inserted merge wahtever be...if rec are reduce then time also reduce but compare to before (when ETL got finished within 2 hrs), so we got more than 100 sec's diffrence b/w that time and now .
    source tables analyzed daily before mapping execution started. and target tables analyzed at evening time .
    As a remeber from last that day nothing any major changes made in ETL mappings. one day there was a problem arise that source_loc for another Process Wonders ( As i told before there are total 3 main Process runs Sun , Wonders and Life_asia,in which sun and wonders are scheduled) so we have correct that loc and deployed the all mappings as requier msg from control center.
    then mappings runs fine but Execution time increased by 1 hrs more(5 hrs+) than before (3-4hr).
    and normal time was
    2 hrs for LifeAsia.
    30 mnt for wonders
    15 mnts for Sun.
    Can you Suggest me what i can do for temp/permanent solution of this problem.
    according to our System config...
    1 tb hdd.in which 2-300 gb free
    4 gb ram
    64 bit windows os
    Used temp tablespace 99 % with auto-extendable
    Used target table space 93-95%....
    data load incrementaly daily.
    load window was 5am to 8 am which is now a days going upto 12 .30 pm
    after which matview going to refresh.
    after which reports and cubes refresh.
    So all process going to delay and this is live process .
    suggest me if any info u want .
    abt hardware config , we need to increase some...? like ram ....memory..etc.
    @wait for reply...
