Cache Seed using iBOTs

I have a requirement to use iBOTs- Cache Seeding
The Dashboard is designed in a way that it has some global filters and then, multiple pages with reports.
When ever user logs in, user selects the global filters and then goes to desired 'page->report'.
Based on that, user gets the details.
Now, I have the requirement for Cache Seeding for those reports using iBOTs. Using iBOTs I was able to get the report seeded in the Cache. But, for that report, I am not able to apply the global filter and hence the am not able to seed the required Cache results. I am clueless at this point on what to do. Can someone help me out in this.
Thanks.

Caching is one of the many approaches to improve performance but it's not a magic solution. You need to understand that you can't cache everything. In particular you won't be able to cache reports that are driven by parameters and have facts that are too granular and exceed the number of rows each cache entry can have. If your fact is of a small size then you can get around the parameters issue by caching a report without any filters. The BI Server should able to derive subsequent queries as long as they meet the cache hit criteria. Have a look at the administration manual for all the rules a cache hit must meet.

  • Cache Seeding using Briefing Books in iBots

    Hi All,
    I'm trying to seed the cache using Briefing books in iBots.
    1. Created the Briefing book of a Dashboard page with required dashboard prompt values
    2. Selected this 'Briefing Book' as Delivery Content
    3. Scheduled the iBot
    But, despite of iBot running successfully, Cache is not being seeded.
    Am i missing any steps?
    Moreover, in 'Destinations', if i just check 'Interactive Dashboards' & 'Active Delivery Profile',
    No cache entries created
    But if i check 'e-mail' or any of the devices,
    then a cache entry is generated for the default dashboard prompt values* but not for the prompt values selected for the Briefing Book*..
    Please help
    Thank you,
    Raghu

    Hello Madan,
    Thank you for the reply..
    "Oracle BI Server Cache" can only be used for the answer pages/dashboard pages with default prompt values..
    Any other way to get the Cache seeded for other prompt values too..
    other than the manual seeding
    Thank you,

    Hi David,
    Previously I am seeding the cache by nqcmd utility, its working in some pages and not working in some pages due to the repository variables (current quarter and current week variables are used in the prompts) used in some Dashboard prompts.
    So we are not meeting Business SLA due to this issue.
    Now I am trying seed the cache through Ibots where ever we have the cache seeding problem. When I run an Ibot, I don't see any Queries cached in Manage--->Cache in Admin tool.
    We already had a Ibot setup which is running after every ETL load in the production and sending reports(emails) to the users ( In this case I see that the queries are cached).
    In the same way I am trying to setup the Ibots not selecting and any recipient and selecting destination as OracleBI Server Cache.
    Am I missing anything here ....
    Please help me guys... this is a production issue....
    Thanks in Advance...

  • Should we Use cache seeding iBots to pre-cache the reports ?

    Hi Everyone,
    We have requirement from client to improve the performance of some reports.We have a very old RPD and it is really huge so we don't want to do much on database side for performance tuning.
    Will it be a good idea to use cache seeding iBots to pre-cache the reports ?
    Most of the reports which are having performance issue are having some 5-6 columns and one key column is having some 30+ choices in column selector.So for each column selector view we will have to create a ibot which will again be a huge task.Can you pls guide how to approach this?
    Thanks in advance !

    hi Aarti,
    Will it be a good idea to use cache seeding iBots to pre-cache the reports ?http://www.artofbi.com/index.php/2010/03/obiee-ibots-obi-caching-strategy-with-seeding-cache/
    30+choices in column selector will definitely have performance issues..bcz each and every time the report is going to refresh .have u enabled the cache some what better .Whats the issue of using existing report by enabling the cache seeding in ibots?

  • Seeding Cache using iBots

    Hi,
    I am trying to seed the cache by using iBots. I am checking OBI Server seeding cache option in the destination tab and also i am selecting the report which i want to seed the cache in the content tab. iBot is executing but the report result is not seeding into the cache. I have checked all the tables in the physical layer the cacheable check box is selected. In instance config.ini file cache is enabled.
    when i check the iBot log file it is saying NoData.
    I have followed the steps in the documentation but its not working.
    Is there any thing i am missing out here? if any one the solutions please let me know as soon as possible.
    Thanks,
    Sankar

    What if you just run the request normally does it cache the query? Also we have seen on our end that the query results exceed the INI limits (# of rows, size, etc.). Verify that too.

  • Report not hitting pre seed cahe created using iBot by Admin

    Hi,
    We created an iBot to pre seed the cache using Administrator and it is creating the cache but when normal user run this particular report for the 1st time it's not hitting the cache(created using iBot). all the subsequest users request hitting the cache created by normal user. I still dont understand why it is not hitting the cache.
    Did anyone comeacross this issue before?
    what are the reasons not hitting cache with above scenario??
    does cache created by administrator using ibot work for other users? we actually running whole query with no filters on it using admin and normal users run the same report with some filters on it. as per oracle cache strategy it should work but it's not.
    any help appreciated.
    Thanks

    Hi Jay,
    I have given some inputs.
    The way the OBIEE server creates the SQL (both logical and physical) for a request can be a bit funky sometimes, the cache seeding only really works in fairly simple cases. Does your request have a pivot table in it by any chance? These are notorious for not caching properly, if you look at the log for the request you can see why as the server adds this strange "aggregate by" to the request (why this can't be done at the presentation level since the only change you are asling for is in the presentation of the content is beyond me). Those "aggregate by"s tend to stop a request being a cache hit unless it is identical to the one that seeded that cache, any change in parameters, columns etc (even if a logical subset) will not get a cache hit.
    2. "Oracle BI Server Cache" Cache Seeding option present in Destination tab of Delivers -- Please check this option.
    3. Caching is one of the many approaches to improve performance but it's not a magic solution. You need to understand that you can't cache everything. In particular you won't be able to cache reports that are driven by parameters and have facts that are too granular and exceed the number of rows each cache entry can have. If your fact is of a small size then you can get around the parameters issue by caching a report without any filters.

  • Cluster aware cache seeding

    Metalink mentions that the Cluster aware cache can only be seeded using ibots or using SAseed command line.
    Does nayone one know if progress has been made so that answers query also results in cache seeding? Also wondering if Marketing segmentation queries can be seeded. ( we tried and do not see any chache using anwsers and marketing).

    I assume you are talking about coherence.
    Cache should be shared across WebLogic clusters, as long as the coherence client node (the individual weblogic server) is configured at network level to connect to the same Coherence Cluster (see tangosol-coherence-override.xml for more info on network parameters). Updates to a cached object should be reflected across all instances of Coherence cluster.
    you can choose to which Coherence cluster to connect by passing to CacheFactory.getCache() a classloader where a separate Coherence configuration has been loaded
    this is all I know about coherence :o) .
    If someone finds this info is wrong, please correct me.

  • How to add reports to ibots for cache seeding

    hi all,
    i am having 10 reports i want to seed- cache automatically everyday for all my reports using ibots .can any one help me in providing steps
    thanks in advance

    Do you know how to create an iBot? If you do, then just chain the iBots to fire one after the other or schedule them separately. There is a checkbox to seed the cache. Take a look and you will see.

  • Problem with iBot cache seeding

    Hello,
    I am trying to seed cache with iBots. It works just fine for many of my reports, however there are 2 reports that are not working properly.
    First of all, running the two reports by themselves (no iBot) results in the cache being populated.
    Second, running the iBot for each of these two reports also seeds the cache.
    The problem is that after running the iBot to seed the cache for each report, when I go to the report in the dashboards and then view the session log, it is not hitting the query that was cached by the iBot. It is generating a new entry in the cache. I am positive that the iBot is created on the correct report and the other options are configured exactly like my working iBots.
    Any ideas?
    Thanks

  • Cache seeding problem

    Hi Folks,
    This may be a Bug as i understand from my previous readings in the forum or misconfiguration in the ibots
    The Cache seeding technique is not working for Users on dashboard pages
    users mean who are not part of RPD and Presentation server Administrator Group
    this users has Read Only Access to the dashboards
    The Setup includes
    1. LDAP Authentication
    2. External Table Authorization
    3. No users in RPD
    Administrators will schedule the ibots for cache seeding on Dashboard Pages,
    Ibots successfully run for users in Admin group and just start and stop immediately with out any errors for users( Non Admin Group people)
    is this well known issue or bug
    is there any workaround
    i have Escalated an SR with Oracle Support, but no USE
    Please Suggest
    Thanks

    Are you sure your iBots are running successfully?

  • Cache Seeding in 10 g

    Hi Gurus,
    I was trying to Cache Seed the dashboard and i am able to make it. But the problem is the Dashboard have prompt with 5 columns ( Together with one go button) and each column have at least 4-5 values. Each column have assign value. When i seed the Dashboard the Cache is done for that combination but when i change the combination of the prompt its generating the cache. Is there any work around that i can do the seeding for all the combinations at one go?
    Prompt:
    Column --> Operator -->Control -->Show -->Defualt to -->Set variables
    Column 1: -->is equal to -->Drop down -->Specific Value( x) -->None
    Column 2: -->is equal to -->Drop down -->Specific Value( 1) -->None
    Column 3: -->is equal to -->Drop down -->Specific Value( y) -->None
    Column 4: -->is equal to -->Drop down -->Specific Value( 23) -->None
    In iBots we can add only one report/ Dashboard? Is there possiblity to add more then one report/ Dashboard.
    Thanks In adavance
    Regards
    Ali

    Hi Ali,
    yep, the link provided above is one way of solving your issue. Also, the Oracle guides are pretty helpful in this area:
    http://download.oracle.com/docs/cd/E17904_01/bi.1111/e10541/querycaching.htm#insertedID4
    http://download.oracle.com/docs/cd/E17904_01/bi.1111/e10541/querycaching.htm#i1010207
    1. Basically, the approach is to call the ODBC client utility (nqcmd) using a script file.
    2. Inside the script file write your SQL statements (BI Server logical format).
    3. There are also some reserved commands you'll find useful like:
    - SAPurgeAllCache
    - SAPurgeCacheByDatabase
    - SAPurgeCacheByTable
    - SAPurgeCacheByQuery
    For clearing out / purging your cache.
    4. SAPurgeAllCache() is commonly used, but 'SAPurgeCacheByQuery' might be more useful for your needs because its bit more precise.
    Hope this helps.

  • Delivers unable to refresh Report through Cache Seed

    Hi
    I am using delivers to refresh the Oracle BI cache.
    I have created a Report & run the report, saved.
    Cache was enabled at this moment. Now the report was cahed.
    I have created a iBot on this report and sheduled.
    After this... i updated one of the values of column in database.
    Now i try to schedule the report as i thought that the cache will be refreshed.. for this iam checking the check box "Oracle BI Server Cache" Cache Seeding option present in Destination tab of Delivers. When i fired my iBot at this moment i am unable to get the updated records which means the cache is not refreshing...
    Can you explain procedure how to refresh the Oracle BI Server Cache.
    What is the Cache seeding..?
    Thank You..
    G. Kishore

    Seeding cache means you are employing a mechanism (manual or automatic) to pre-populate the cache entries so your first user(s) don't have to wait for data to be displayed on the screen.
    To seed a cache one presumes the cache is empty -- at least for the entries in question. You might have some data that changes yearly ... so you never remove those cache records unless the year is done. You might have daily data that you need purged and re-seeded every morning. You might have such good database query/network/BI Server performance that your users will actually perform the seeding for you (but then it can be argued why have the cache at all); but usually the DB/network/BI Server performance is such that we want to cache data, purging and re-seeding as needed.
    Also keep in mind: caching is the LAST step in a comprehensive OBIEE performance strategy.

  • Cache seeding

    Hello All.
    I have several dynamic variables used in a analysises and graphs and then in they used in a dashboard.
    I have a schedule task running to refresh the data (cache seeds).
    I have recently learned that if I utilize dynamic variable then the cache is purged by the BI server.
    And the user offers a solution to "set up a cache seeding .bat file that runs after the dynamic variable has been updated. "
    We are using Oracle BI 11.1.1.5.0
    Can anyone clarify how to do this?
    Perhaps this issue was resolved already by Oracle??
    Thank you,

  • Cache Seeding in OBI 11g in Clustered Environment on Unix Box

    hi All,
    i want to do cache seeding for a couple of dashboards in OBI 11g,
    Steps taken:
    1. Global Cache is ON
    2. Global shared path is SET
    3 Global cache size = 3GB
    i am using agents for cache seeding and are scheduled after the dataload is complete.
    It successfully runs early morning...delivers a mail.
    But when I am trying to the reports from OBI...its again generating the SQl...without hitting the cache.
    It might be due to the Clusterred Env... 2 nodes Env.
    Please suggest some technique to achieve this cache seeding.
    Thanks in advance

    GLOBAL_CACHE_STORAGE_PATH This path must point to a network share. All clustering nodes share the same location.
    Check the bellow setting
    GLOBAL_CACHE_STORAGE_PATH = "directory name" SIZE;
    ex: GLOBAL_CACHE_STORAGE_PATH = "C:\cache" 250 MB;
    CLUSTER_AWARE_CACHE_LOGGING -->Turns on logging for the cluster caching feature. Used only for troubleshooting. The default is NO.
    Example: CLUSTER_AWARE_CACHE_LOGGING = NO;

  • What is cache seeding and cache purging

    hi all gurus

    please can any one tel me bout it,

    Thanks

    Hi,
    Seeding in simpler words means Filling/loading in according to the context.Where as Purging means removing or cleaning of data.
