Hi,
The persistent cache allows to save the lookup cache and use them the next time informatica processes lookup transformation.
This concept works only if the lookup transformation is configured to use the cache.

If we set cache persistant time in physical table is there any issues we wi

hi all
one small question i have that is ,
with out using event pooling tables,if i set the cache persistent time ,will i face any problem?
any disadvantages will i face ?
Thanks

hi,
set the cache persistent time ,will i face any problem?no problem at all but it is for each any every time .....let say if u set the time as 2minutes but after a year some one has updated the table wanted to see results in a minute then u already setted the parameter to 2 minutes the cache presistent time u need to change manually where as coming ton the event polling no need of that it ll update directly...maintainence purpose event polling is best one

How to disable or decrease Cache persistance time in dashboard?

Hi everyone,
I have used the AUTHORIZATION concept in my OBIEE project with the help of AUTHORIZATION table in SQL database.Here,in database table, records have User-ID with other coloumns like name, email, etc with groupname also.
It is working properly, but when i make some changes in AUTHORIZATION table in database , like adding new user or changing group membership of some existing user, it doest reflect in dashboard link IMMEDIATELY.
For example, user SHYAM is member of Organization Head group and Vertical Head group. So, he can see report of both the groups.
But , if we update his group membership to Vertical Head group only, by deleting Organization Head group membership in Database,
the respective change do not reflect in dashboard.
I have to restart the obiee services on server.
only then changes are visible.
Is there any way to disable the CACHE completely....
or Atleast decrease the cache persistance time to least , i.e, few seconds or completely to zero.
Please help me by giving some solution.....

In your init block which fetches the group membership for a particular user for the variable target chose row wise intialization and unmark 'Use caching' option.

MSI Installer Cache & "Persist in Client Cache"

Hello,
I'm predominantly using the Application Model and just a few Packages. I'm noticing on Software Deployments that the Downloaded Content eventually gets purged and then when a user goes to launch the software it states that it cannot find the reference
MSI within CCMCache. I talked to some other people and they said that Packages would automatically put the cache in the Windows Installer Database to eliminate that issue and weren't sure how the Application Model handled this. Is the only way
for me to fix this to set the application to 'Persist in Client Cache?' If so, I have a lot of things to redo.
Looking for advice and how this is supposed to work under both the Application and Package Model.
Thanks!

As long as you supply the product code at the bottom of the Programs tab on the Deployment Type, then the same thing will happen for applications. Essentially, the client agent adds a location from the DP to the source path for the MSI to enable
repairs.

Hmm. These were standard MSI's that were imported so all of those codes should have imported in correctly? Not sure why I'd be seeing issues from clients.

Automatic Purging Cache

Hi Guys,
I am facing this issue of purging the Cache of the Repository everydat manually.
Is there any mechanism through whihc I can purge the cache automatically after a day or after certain size of Cache?
Thanks
Saurabh

Hi Saurabh,
To purge the cache automatically you have to set the cache persistent time in the tables present in the physical layer. There you can mention the time after which you want to purge the cache. The steps are provided below:
1. Double click on the table in the physical layer.
2. Select the General tab.
3. Select the Cacheable option.
4. Select the Cache Persistent time.
5. Specifiy the time interval when you need the cache to be refreshed.
You have to do the same for all tables for which you want to purge the cache.

Cache purging in Physical table

Hi Gurus,
there is cache never expire and cache persisitent time avl in every physical table avl in physical layer of obiee. i wanted to know if we will set the cache persistent time for 10 mins then how it will purge the cache automatically
thanks

Hi Gurus,
I totally aggre with you but can you please pay you kind attenetion towards bwlow points
Are you sure that the physical table cache purging done oracle bi server
and that is not visible to track by the Administratortr
what about cache never expires-- can we purge this cache from cache manager

Worm up cach in Bex reports

Hello,
Inorder To "worm up the cache" of a report i've made a web template to it, changed its properties (via RSRT) to cache mode 4-persistent cache across each application server, persistent mode 3-tranparent table(BLOB) and generate the report. The report use a variable of calc year\month. I made a variant for the variable with the values 1.2005 - 12.2005. When i run the report with exactly the same values in the selection screen it runs very fast but when i put 1.2005 - 9.2005 it becomes very slow like i didnt worm up the cache...
Please Advice,
David

I have to agree with Jeff LaRuso on this. It should work based on what you have described.
Although I'm sure you have it setup, let's backup a bit and verify that Global Cache is active on the Appl Servers the query is running on. Even though you are not caching to main memory, global cache still needs to be on. The query could be looking in the local session cache and finding the results which could explain why the idnetical query runs very fast.
When you say you have the variable marked as can be changed during navigation - that means you have an X in the box, correct?
You've verified thta the variable you are using in the query is the variable you have marked as changeable?
Any idea how big your global cache is? There is a setting somewhere that sets athe maximum size of a result thta can be cached as a percentage of the OLAP cache - I'm not certain if that would apply to a result set that is be cached persistently, but you never know.
What Version and Svc Pack are you on?

Presentation Cache

Hi All
BI server cache can be deleted through 1. BI tool --> Manage Cache, 2. Setting up Cache persistant time for that table & 3. Through Event Polling tables
how can we delete the presentation server cache? how many ways we can delete

Hi,
You can manually Close all the cursors or running queries thru settings->Manage session log. However if you want to automate this refer to your instanceconfig file to get the cache directory and come up with a shell script to delete all the cache files in this directory. Hope this Helps
If this helps mark the same as helpful

under your vserver redirect, instead of configuring 'serverfarm cache' configure 'serverfarm cache backup forward'
If the serverfarm cache goes down, the CSM will use the backup which is a forward.
However, in this case, the response from the server will probably not come back to the CSM, so you should configure the vserver with the command 'unidirectional' as well.

How do I create DRM Licenses that can be used for Offline Playback?

[ Background ]
Typically, a license is acquired from the DRM license server when the client video player encounters a video that is DRM-protected.   However, some use cases call for the ability for end-users to be able to play DRM content when a network connection is not available to the device.
For example - the user wants to download a video from their home, acquire a license to play the content, and then get onto a train/airplane where a network connection isn't available. On the train/airplane/etc..., the end user expects to be able to watch their video that they downloaded at home.
[ DRM Policy Requirements ]
For this use case to be possible, the DRM license must be acquired when the network connection is available. In addition, the DRM license must be allowed to persist on the device disk. For this to be possible, one value must be present in the DRM policy:
1. Offline License Caching must be set to 1 or higher. This policy parameter indicates how many minutes a license is allowed to be persisted to disk once it's been acquired by the license server.
[ Workflow ]
Now that the content has been packaged with a DRM policy that allows for offline caching (persistance) of a license, the video player simply has to acquire the license before the network connection is lost. This can be accomplished via the typical API calls that the Video Player Application Developer would use to do a normal DRM license acquisition (DRMManager.loadVoucher()).
For example, by using the DRMManager ActionScript3 API: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/drm/DRMManage r.html
For other platforms supported by Adobe Access DRM (iOS, Android, etc...), please refer to the appropriate documentation around playback of DRM content on how to pre-fetch the DRM license.
[ Workflow - iOS ]
Enabling offline playback using the Primetime Media Player SDK (PSDK) for iOS requires a bit of self-extraction & instantiation of the DRM Metadata from the m3u8. The reason for this is that as of PSDK v1.2, the PSDK APIs do not expose an mechanism for extracting the DRM metadata.
You must manually (outside of the PSDK) get access to the DRM Metadata, instantiate a DRMContentData, and then use the DRMManager class to obtain a license for your content. Afterwards, you may download your HLS content and stream it to your video player application locally. Since the DRM license was pre-acquired before playback of the downloaded HLS content, your video player application does not require a network connection to acquire a DRM license. Below is a code sample of obtaining the DRM Metadata from the m3u8 manifest and then using it with the DRMManager singleton.
/*          Main entry points, playlistURL is url to a top level m3u8. */
void PlayContent(NSURL* playlistURL)
          DRMManager* drmManager = [DRMManager sharedManager];
          if ([drmManager isSupportedPlaylist:playlistURL])
// First we need a handler for any errors that may occur
                    DRMOperationError errorHandler = ^(NSUInteger major, NSUInteger minor, NSError* nsErr)
/*          report error. */
/*          Synchronous call to DRM manager to extract DRM metadata out of the playlist. */
                    [_drmManager getUpdatedPlaylist:playlistURL
                                                                                  error:errorHandler
                                                                                updated:^(NSURL *newPlaylist, DRMMetadata *newMetadata)
                               (void) newPlaylist; /*          updated URL is not used for this code sample. */
                               if (newMetadata)
                                                  Assumes we are going to try to satisfy requirements to acquire license on the first policy in the metadata.
                                                  If there are multiple policies in the metadata, only 1 of them need to be satisfied for the license request to
                                                  go through.
                                         DRMPolicy* drmPolicy = NULL;
                                         for (id object in newMetadata.policies) {
                                                   DRMPolicy* drmPolicy = (DRMPolicy*)object;
                                                   break;
                                         if (drmPolicy == NULL)
                                                   /*          report error, this metadata is malformed. DRM metadata must contain at least 1 policy*/
                                         if (drmPolicy.authenticationMethod != ANONYMOUS)
However, please note that the above only describes the DRM license handling for offline playback. The actual playback of video using the Primetime client SDK is not officially supported. You will have to use your own mechanism of saving and playback back HLS content locally within the application.
Theoretically, it is possible to save the HLS stream to the app, and then embed an HTTP server to the app to stream the HLS content back into the application. However, the Primetime client SDK doesn't not expose a way to do this directly, since it's not yet supported.

Updating more than one database...

I am looking at a scenario were we, each time a change is made to several different caches, needs to update both a legacy database (main frame, non-relational = actually hierarchical) that are used by several large batch applications (that will be converted one by one over time to use the application built on top of the cache) as well as a new database (modern hardware & OS, relational, organized in a quite different way than the legacy database!).
     The sync requirements are:
     * It is REALLY bad if only one database get updated but not the other!
     * The legacy database can be about 5 minutes behind the cache
     * The new database is only used for making the cache persistent (it is fully loaded to cache at system startup) and has really no requirement at all on how much behind the cache it can be as long as data is never lost (we will use backup count = 1).
     Updating the legacy database is NOT straight-forward and will require some data transformations to be performed. They can either be done in the legacy system (if we send the change info using some safe messaging for instance) or in the new environment if we want to update the old database directly.
     A factor complicating things further is that the legacy system have some consistency requirements on the data (in particular when creating new objects that has relationships to each other, you may think about order / order row even if this is not the kind of application we have in mind).
     For performance reasons (and since it seem from another thread that partial writes is a bigger problem with write through) we would probably like to use write behind to update the new database.
     Anybody who have some experience of similar situations and can give some suggestions on how to best go about it?
     Best Regards
     Magnus

I may also add that our current thinking is to use a "write beside" pattern for the legacy system and a write-behind pattern for the cache to update the new database. An XA transaction will then be used to make sure that both or neither the old system and the cache gets updated. Does this sound like a reasonable solution?
     Best Regards

Hi,

     }catch(...){
}What are the System Properties? Are you running the client remotely? Are you running the client as a stand alone Java app or using the Weblogic's Client Runner? 'java:comp' as the jndi name is usually used when the client runs inside the container... But it doesn't seem to be the case.
