Data in cache
Hi,
Webdynpro session variable should not be used, as it will be the violation fo rule Webdynpro inner classes should not be used.
Whats the way to put data in cache for a user. I have 8 different projects and deployed on Portal and used as webdynpro iViews.
Now for the logged in user, how to maintain data in cache, so that no need to access the data again from database for the same queries.
Nav,

Data Buffer Cache Error Message
I'm using a load rule that builds a dimenson on the fly and getting the following error: "Not enough memory to allocate the Data Buffer Cache [adDatInitCacheParamsAborted]"I've got 4 other databases which are set up the same as this one and I'm not getting this error. I've checked all the settings and I think they're all the same.Anyone have any idea what this error could mean?I can be reached at [email protected]
Hi,
Same issue, running Vista too. This problem is recent. It may be due to the last itunes update. itunes 11.2.23 -
Hi I am using Jdev 11.1.1.7
I have a POJO based Data control which am using for tree structure.
I have this tree inside a popup.
So when cancelling or after the purpose of the popup is over.
I want to clear the cache of the data control.
I tried several ways to do that like having a methods in my java class where making the object null and calling the methods on cancel.
But nothing worked .
How to clear the Pojo DC.Hi AlejandroTLanz ,
I tried the above method.
I created a method in Java class which is used to make the List null used by the tree.
And then calling finditerator.executequery.
I could see that the list is getting null.
But In Java sampler It still shows that Objects are present.
I guess the Object are still in data control cache...
I tried to clear the DC Cache by calling the DC.resetMethod.
But nothing worked -
I have a few Questions regarding Data File cache and data cache. based on teh size of the application.
All the settings are changed by using a maxl script.
1. Data File cache-50MB,Data Cache - 100MB
I am using Buffered I/O, then will memory be allocated to Data File cache?
2. It is given in DBAG that data cache & index cache should be set as small as
possbile for both buffered & Direct I/O. The size of one of my application is
around 11 GB. data file :11GB,index File :450MB
I have set my index cache to 450MB and data cache to 700MB.
Is it OK or a. what should be my data cache size?
b. How do I calculate the optimal Data cache and index cache?
3. the memory size of our AIX server is 6GB. If i use Directo I/O, can my sum of
all caches be 4GB?
4. If I use buffered I/O, according to (2), what should be my cache sizes?
Thanks
AmarnathIn the DBAG it states data file cache is not used with buffered IO so the answere to 1) should be NO.
For 2) there is a hint in the DBAG that you should check the hit ratio of the caches to verify sizing, only calculatory advice for sizing is given on the calulator cache :-( This would mean for 2b) look at the hit ration if it stays around 1.0 try to decrease it until it drops slightly. Inspect the ratios from time to time.
3) don't know, 64bit should be no problem. But why would you do this anyway?
Example form our settings pag total ~20GB ind ~2GB
outline hat 11 dimensions with a block size of ~340KB largest dense ~400 members, largest sparse ~4000 members, existing blocks ~2.7 milions
The data cache is set to 256 MB, the index cache to 64MB our hit ratios are 1.0 for index cache and 0.77 for data chache. so our data cache could be larger, but the performace of retrievals is around 3.0 seconds which is fine for our users..
4) Check your hit ratios and try to increase or decrease the cahces in small steps (first I'd do the index cache, the if it's fine I'd tune the data cache).
hope it helped a bit.. -

When you updated value 2 to 4, so still its uncommitted then the transaction is active and it will be in buffer cache itself. Of course if the cache is full or performed any checkpoint, then this modified data also writtened into data files. So you should not mention dbwriter not writes to datafiles you cant predict when cache going to full or checkpoint occurred. -
Hi Guru(s),
Please anyone can tell me that, how can we check the size of data buffer cache.
Please help.

How much data canbe cache in SGA
Hai everybody,
my company using Oracle 11g 11.2.0.1.0 - Production database, my os is RHEL 5.5 ,my server's physical memory is 30.9 GB ( cat /proc/meminfo ) ie the SGA size [ (30.9*40/100)=12.5 GB ] so i use 12.5GB SGA size for one instance, we need to cache some data for our application performance how much data can cache in SGA based on 12.5 GB or how to calculate how much data can cache in SGA without any performance degradation.
Regards BenkAman has it right. WHY?
the keep pool, alter table cache, etc - I would not be doing ANY of these without a good reason.
Often times, people think that forcing a table to stay in the cache is a good idea. It rarely is. If you want things in the cache, use them. If they are used, they will naturally have their blocks cached. If you don't use them, they can get flushed out. But if you don't use them, why do you want them using memory that could better be used by other things?
My advice: don't try to second-guess Oracle's memory management and caching strategy. If you think you have a reason to, post it here and we can help you (or debunk your reason). Based on the fact that you've apparently calculated the SGA using that silly, meaningless "rule" that says give it 40% of your total RAM, I'd guess that you are looking around for a magic bullet, and you don't actually have a problem to solve.

Data Target CACHE not known in APD
Dear All,
I have created CRM extension thru EEWB and also i have created necessary query at BW side. Now when i try to create Analysis Process thru APD, i am not able to add my Analytical Data Storage wat i have created in CRM thru EEWB.
It is giving "CRM error: Data target CACHE;ZSBP not known" where ZSBP is my ADS created on CRM.
Is this some authorization issue or wat? Plz suggest.

Hi Everyone,I have been away from Essbase for a little while and in the mean time our client made the move to Essbase v6.Could somebody please explain the significance, and correct way to set, the Data File Cache? Also, have the rules for setting the Data Cache changed as a result?Any advice would be appreciated - I understood Essbase v5 quite well but have been out of the loop as far as Essbase v6 goes.
The data file cache has significance only if your client is using Direct I/O. Direct I/O was introduced beginning with v6 to allow DBAs to explicitly manage data file caching on a database by database basis rather than allowing the operating system to do it. The previous I/O management scheme (Buffered I/O) was still supported, but Direct I/O was the default.Unfortunately, in installations with multiple applications per server, optimizing the data file cache for each database proved to be a headache. So Hyperion decided to revert to Buffered I/O as the default beginning with v6.2. So in Essbase version 6.0-6.1 Direct I/O is the default and you have to change it in essbase.cfg to use Buffered I/O. In version 6.2 and later the reverse is true (please correct me if I'm wrong everyone).If you choose to use Direct I/O, I believe the conventional wisdom is to make the data file cache big enough to hold all the .pag files in your database. Otherwise, set it as large as possible.Good luck,Bruce---Message Posted by sparky1 ??4/7/02 19:44---Hi Everyone,I have been away from Essbase for a little while and in the mean time our client made the move to Essbase v6.Could somebody please explain the significance, and correct way to set, the Data File Cache?

Help Needed in persisting data in cache from CEP on to a database
Hi,
We are trying to create a Oracle Complex Event Processing (CEP) application in which persist the data stored in the cache (Oracle Coherence) to a back end database
Let me provide you the steps that I have followed:
1) Created a CEP project with cache implementation to store the events.
2) Have the following configuration in the context file:
<wlevs:cache id="Task_IN_Cache" value-type="Task" key-properties="TASKID" caching-system="CachingSystem1">
<wlevs:cache-store ref="cacheFacade"></wlevs:cache-store>
</wlevs:cache>
<wlevs:caching-system id="CachingSystem1" provider="coherence">
<bean id="cacheFacade" class="com.oracle.coherence.handson.DBCacheStore">
</bean>
3) Have the following in the coherence cache config xml:
<cache-mapping>
<cache-name>Task_IN_Cache</cache-name>
<scheme-name>local-db-backed</scheme-name>
</cache-mapping>
<local-scheme>
<scheme-name>local-db-backed</scheme-name>
<service-name>LocalCache</service-name>
<backing-map-scheme>
<read-write-backing-map-scheme>
<internal-cache-scheme>
<local-scheme/>
</internal-cache-scheme>
<cachestore-scheme>
<class-scheme>
<class-name>com.oracle.coherence.handson.DBCacheStore</class-name>
</class-scheme>
</cachestore-scheme>
</read-write-backing-map-scheme>
</backing-map-scheme>
</local-scheme>
4) Have configured tangosol-coherence-override.xml to make use of coherence in my local machine.
5) Have written a class that implements com.tangosol.net.cache.CacheStore
public class DBCacheStore implements CacheStore{
But when I try to deploy the project on to the CEP server getting the below error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'Task_IN_AD': Cannot resolve reference to bean 'wlevs_stage_proxy_forTask_IN_Cache' while setting bean property 'listeners' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'wlevs_stage_proxy_forTask_IN_Cache': Cannot resolve reference to bean '&Task_IN_Cache' while setting bean property 'cacheFactoryBean'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'Task_IN_Cache': Invocation of init method failed; nested exception is java.lang.RuntimeException: Error while deploying application 'AIT_Caching'.

Bad Data from Cache after infoprovider update
Hello,
We have queries running off of a multi-provider consisting of 4 cubes. Occasionally when we generate quires after deltas have been loaded into the cubes we get incomplete or bad data. Deactivating the cache or deleting the cache and runing the query again always seems to resolve the problem.
Any thoughts on what the issue might be and how to resolve?
Thanks
Stan PickfordStanley,
after any data change in an InfoCube, table RSDINFOPROVDATA should contain the timestamp. This timestamp is used by the OLAP cache to determine if new data has been loaded or if the cache is still valid.
I'm not aware of any problems. If it is reproducible and you can't fix it, open a message to SAP Support.

5 months rolling monthly report by fetching data from cache & Database
Scenario: One monthly report would be created each month end which contains one summary tab and other details tabs. Summary tabs will contain the data of all the months summary data (current month and previous months)
Problem:
Current month data have to come directly from database and previous months data come form cache and whole thing will be cached this time so that when we run next month report the data till this month will also come from cache.
Any one please help me ASAP.What's wrong with F_GET_COMPANY_CODE ? Below is similar code - try running this and seeing what you get:
report zlocal_jc_t001w.
tables:
t001k, "Valuation area
t001w. "Plants/Branches

p_bukrs like t001k-bukrs default '1000'.

As for links to locally defined database tables, that will depend on what the keys defined in SE11 are e.g. there will be a primary key plus relationships to other tables (for example "WERKS LIKE YSDA_EXP_PRTLOG-YY_PLANT" indicates YY_PLANT relates to T001W).

Is there any way that I could signal daat buffer cache to write all data to data files if amount of dirty blocks reach say 50 Mb.
Iam processing with BLOBS, one blob at a time, some of which has sizes exceeeding 100 Mb and the diffcult thing is that I cannot write to disk until the whoile blob is finished as it is one transaction.
Well if anyone is going to suggest that to open, process close, commit ....well i tried that but it also gives error "nmo free buffer pool" but this comes for twice the size of buffer size = 100 Mb file when db cache size is 50 mb.
any ideas.Hello,
Ia using Oracle 9.0.1.3.1
I am getting error ORA-OO379 No free Buffers available in Buffer Pool. Default for block size 8k.
