Programatically invalidate/validate cache for specific query

Hi,
I am looking to programatically invalidate and re-instantiate the cache for a specific query.
I know how to perform this manually via RSRT, RSRT1/2....etc. What I am looking for is a way to schedule this and programatically control caching on specific query.
Any help would be wonderful!!
Thanks!

hi Dong Suk Choi ,
the technical information which u have furnished clearly says that the settings
that u have made does not enable the query to use cache.
u can enhance cache by customizing the inforovider or in the transaction rsrt
even if the concerned query does not have required settings u can make them in rsrt tcode.
goto rsrt set the read mode and cache mode as u wish, however default settings would give optimum performance.
and run the query.
in the rsrt screen a push button execute + debug enter that and unmark the check box do not use cache.
hope this helps.
reward points if helpful.
bye.

How to empty out Olap Cache for a query?

Hi experts,
I think the olap cache for a query should be resetted to zero after a data load (right?), if i have understood well how it works. Where can i check the olap cache for the query? I'd like to ckeck the change of the Olap Cache for a specific query.
I checkt in the Cache Monitor but I haven't found any data.

Hi
You can use the Transaction code RSRCACHE

Pre-fill the OLAP cache for a query on Data change event of infoprovider

Hi Gurus,
I have to pre-fill the OLAP cache for a query,which has bad performance.
I read a doc 'Periodic Jobs and Tasks in SAP BW'
which suggested sum steps to do this
i hav created the setting for Bex broadcasting for scheduling job Execution with data change in info provider
thereafter doc says "an event has to be raised in the process chain which loads the data to this InfoProvider.When the process chain executes the process u201CTrigger Event Data Change (for Broadcaster)u201D, an event is raised to inform the Broadcaster that the query can be filled in the OLAP cache."
how can this b done please provide with sum proper steps
Answers are always appreciated.
Thanks.

Hi
U need to create a process chain or use the existing process chain which you are using to load your current solution, just add event change process type in the process chian and inside it add the info provider which are going to be affected.
Once you are done with this go to the broadcaster and create new setting for that query...you will see the option for event data chainge in infoprovider just choose that and create the settings.
hope it helps

Cache mode for specific query

Hello BI guys,

Breaking FMS Caching For Specific Video(s)

We occasionally run into a condition that appears to require cache breaking. If a user rotates a video that has been recently played and the video is currently in the FMS cache, subsequent requests for the video will continue to show the unrotated video.
Is there a way to break the FMS cache for a specific video? If not, I would be equally curious for a way to clear the cache completely, though this is going to cause a much larger performance hit than I would hope for.

I suppose it should be one of the properties passed to the query findmethod (Query.query.find(String,

I was unable to locate any documentation or examples for the question.
What is the key set the Properties? I know the "GROUP_NAME" is one,which

Wrong cache for input-ready query

Dear Expert,
I encountered some issues about input-ready query. When I first open one input-ready query and input some plan data, I can save the data successfully. But after I saved data for the first query, if I don't re-connect the analyzer and open a new query, usually the plan data in the new query can not be saved successfully. After re-connect the analyzer, it works well. When I debug it, if I do not re-connect analyzer, I found the new query I opened still got some data which belong to the first query (Such as variable value). I guess it probably caused by some Bex cache? (It's not OLAP cache in RSCACHE, as we have disabled the cache for planning query in RSRT).
Could you please help me with this? Is there any way we can disable this kind of cache for the input-ready query? Or if we have any solution to clear this kind of cache without re-connect bex analyzer every time when I open a new input-ready query.
Thank you in advance.

Fuyang

Hi Fuyang,
We are facing similar problem.
1st problem:
(1) When we run workbook that time variable values are automatically filled up.
(2) Variable values for version, year is filled up and then query output is displaying.
(3) There is no personalization or variant used. Its looks to me Values are coming from Cache.
(4) Cleared RSRCACHE and there is no cache used for this query.
(5) If we enter version = u201CZ2010u201D and Year = u201C2010u201D and after running workbook (input query) and then closing and reopening same variable values are coming. If we change version from u201CZ2010u201D to u201CZ2011u201D and run/save query and again reopening version variable values are coming again to u201CZ2010u201D.
2nd problem:
(1) We have planning sequence which is using below variables.
(2) Version, Year, Plant.
(3) Version and Year is input ready variables
(4) Plant is Userexit variable.
(5) Plant Dropdown is used.
(6)When we execute planning sequence first time without filtering plant then it is working fine. Receiving message u201C100 records read,100 records changedu201D u2013 This is working fine.
(7) When we use plant dropdown and filtering u201CABCu201D plant then planning sequence working fine and receiving message u201C20 records read, 20 records changedu201D u2013 This is working fine.
(8)When we clear drop down/filter using CMD - REMOVE FILTER which is used in button clear plant u201CABCu201D filter. u2013 This is working fine.
(9) Then we again apply planning sequence for all the records and receiving message u201C20 records read, 20 records changedu201D. This is not working. The message should come u201C100 records read,100 records changedu201D
This time plant variable has still with value u201CABCu201D and not clearing in variable cache.

OLAP Cache for Query Performance

Hi Experts,
I have below 2 Questions before we implement OLAP Cache for our Queries:
1) We have 15 imporatant queries - which do NOT have any variable/selection screen.
(question here is will it work for those kind of queries which dont have any selection screen/ variant ? ) --> client wants to prime the cache for few queries which dont have variable screen.
In this case, say if data is later filtered on any CHAR , will it take the data from Cache?
2) I have a query which initially will have few characteristics in the drill down when we first execute and users would be drilling down on many other characteristics after that. So if I want to fill OLAP cache for this query then what is the best way so that each drilldown in the query gets data from cache.
Thank you,
-Su

Hi Raghavendra,
Thanks for your response.
For first Question, Do you mean , even if we do not have any Selection varaibale on Query--we still can fill OLAP cache for it for its all values (i.e. No selection means "*") ?
If this is the case, then what we need to defile in General Precalculation (Variable assignment) while creating a new setting for the query.
Thanks,
-Su

Purge Cache for a Specific Business Model

Hi everyone,
I have a obiee(11) report purging all cache entries (as Call SAPurgeAllCache()). Is there a method to purge cache partially for specific business model entries and not to purge all the cache ?
Thanks ...

Hi,
To selectively purge, you could use SAPurgeCacheByQuery, SAPurgeCacheByTable or SAPurgeCacheByDatabase. Alternatively, Event Polling Tables may help. See http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1005542 and http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1010207.
Also see the section on BI Server caching here : http://www.rittmanmead.com/2013/03/optimising-obiee-performance-tuning/
SET VARIABLE DISABLE_CACHE_HIT = 1
It will purge the cache for that report.This is just wrong. DISABLE_CACHE_HIT only DISABLES cache use for the query execution, it does not PURGE it
You may go for this DISABLE_CACHE_SEED for more info http://docs.oracle.com/cd/E23549_01/bi.1111/e10540/variables.htm
What's the point of DISABLING use of the cache, if the OP wants to use the cache?
set the cache persistence time for the related physical tables. so based on the time interval u set, at that time specific tables only will get cache purged.This is only the time from which the entry got loaded into the cache, so is not a good way to manage the purging of the cache usually - because it has no relation to when the data got loaded to the database

How to clear Local-Cache Entries for a Query in BW?

Hi There,
i`m student und i need please your help for my Thesis!!
I execute the same Query many times in BEx Web Analyzer und note a Query Response Time under ST03N using each time a different READ Mode and Cache Mode is inactiv (Query Monitor RSRT).
First time i exectue the Query, it reads also from database, second time it uses the local Cache and that `s okay!
My problem is:
When i change the Read mode and execute the Query again, it uses for the first run also the old entries from the Cache so i get wrong response time for the first run!!
I know that while the mode cache inactiv , the local cache will still be used, so how can i delete the local cache entries each
time i change the read mode and execute the Query? In Cache monitor (rsrcache) i find only entries for Global cache etc..
I've already tried to close the session and login in to the System again but it doesn`t solve the Problem!!
i don't have a permission (access rights) to switch off the complete Cache (local and global ).
Any idea please??
Thanks und Best Regards,
Rachidoo
P.S: sorry for my bad english!! i have to refresh it soon:)

Hi Praba,
the entries stored in RSRCACHE are for global cache, there is no entry for my query in Cache monitor!
i execute the query in RSRT using java web button and cache mode inactiv so, the results will be stored in local cache.
this is as below what i want to do for my performance tests in my Thesis:
1. run a query for the first time with cache inactiv and note runtime of it
2. run the query again with cache inactiv and note runtime of it
3. clear the local cache (i don't know how to do it??)
4. change the read mode of query in RSRT then run the same query for the first time and note runtime of it
5. run the query again and note runtime of it.
i'm doing the same procedure for each Read mode.
the problem is in step 4 , The olap Processor gets the old results form the cache so i get wrong runtime for my tests.
Generate the report doesn't help, any idea please?

How to invalidate cache for a single item?

I m trying to invalidate cache for a particular item in the repository.
I dont want to invalidate the whole cache.
Is there a way to do that through dyn/admin?
TIA

You can create own component in dyn/admin to do this.
1. Create a global component with the following properties
/atg/dynamo/service/GSAInvalidatorService
[repository of item to invalidate]
[itemDescriptor]
[repositoryId]
2. Create method invalidateCache
getGSAInvalidatorService().invalidate(getRepository(), getItemDescriptor(), getRepositoryId());
or, this should work as well
ItemDescriptor someItemDescriptor;
someItemDescriptor.removeItemFromCache(getRepositoryId());
Maybe try them both to see what works for you.

CQWP does not return result for a specific query when filtering on a managed metadata field.

Hi,
We are facing a serious production issue. We've search the web extensively but to no avail.
Problem:
CQWP does not return result for a specific query when filtering on a managed metadata field.
ULS log:
The Uls logs provides 3 different messages that I could relate to every time the query is executed. The last item(level Medium) is displayed 14 times. For readability I've moved the ULS logs to the bottom of this question.
Query:
The query is as follows:
(I've translated this from dutch so pardon any typo's)
Query: (top selection) Display items from all sites in the site collection
ListType: Documentlibrary
Contenttype:
Items from this group:Custom Document Contenttypes
Items from this content type: Verklaring
Filter: Soort is equal to X
extra info: the field soort (Type) is a managed metadata field that was assigned the value X
Managed Metadata Structure:
-managed metadata service
-Contoso
    -Enterprise Taxonomy (term set)
      -Document (term)
        -Verklaring (term)
          -Soort (term)
            -x (term)
EXTRA INFO:
When I modify the filter to filter on Title the CQWP DOES return the correct document!
When I modify the query settings to search a specific library the CWQP also does return the correct document! (In this case I am filtering on a managed metadata field).
QUESTION:
Why doesn't the CQWP return the document when filtering on a managed metadata field over the entire site collection.
Why does the CQWP return the document when filtering on a managed metadata field over a single library.
(The type of information the CQWP should return (Soort:x) is stored in a dozen document libraries!)
Here are the ULS logs.

I want to improve it's efficiency but i still do not know how. But possible solutions are:
-i know that a FORALL loop would improve my insert speed but in this case there is a condition so i don't know how to implement it in a forall.
-I want to avoid doing the inner join with billing_account for the query but i do not know if providing the billing_account details in the input table would make it more efficient, is not a lot of data per row, but i am sending 10k rows per SP call, also i am not sure if there will be a lot of context switching with PL/SQL and SQL in case i do that.
Any help would be appreciated, thanks.

Some of the suggestions I can make for improving the Queries are
1) Try using Indexed columns whereever possible , specially when you are joining tables. If there is no index on column that you are using to join ,then either try to use columns which have an index or create a new index on columns if required.
2) Try to see the Explain Plan for the select statements you are uisng. If you are using TOAD, try to use the tool's feature to generate different possible combinations of queries with the least cost. You need to supply TOAD with the problematic SQL statement, it will automatically generate different combinations of SQL statements and then you can choose the one with the least cost or the one with the best Explain plan results.
Hope this helps.

How to create a cache for JPA Entities using an EJB

Hello everybody! I have recently got started with JPA 2.0 (I use eclipseLink) and EJB 3.1 and have a problem to figure out how to best implement a cache for my JPA Entities using an EJB.
In the following I try to describe my problem.. I know it is a bit verbose, but hope somebody will help me.. (I highlighted in bold the core of my problem, in case you want to first decide if you can/want help and in the case spend another couple of minutes to understand the domain)
I have the following JPA Entities:
@Entity Genre{
private String name;
@OneToMany(mappedBy = "genre", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<Novel> novels;
@Entity
class Novel{
@ManyToOne(cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Genre genre;
private String titleUnique;
@OneToMany(mappedBy="novel", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> editions;
@Entity
class NovelEdition{
private String publisherNameUnique;
private String year;
@ManyToOne(optional=false, cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Novel novel;
@ManyToOne(optional=false, cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Catalog appearsInCatalog;
@Entity
class Catalog{
private String name;
@OneToMany(mappedBy = "appearsInCatalog", cascade = {CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> novelsInCatalog;
The idea is to have several Novels, belonging each to a specific Genre, for which can exist more than an edition (different publisher, year, etc). For semplicity a NovelEdition can belong to just one Catalog, being such a Catalog represented by such a text file:
FILE 1:
Catalog: Name Of Catalog 1
"Title of Novel 1", "Genre1 name","Publisher1 Name", 2009
"Title of Novel 2", "Genre1 name","Pulisher2 Name", 2010
FILE 2:
Catalog: Name Of Catalog 2
"Title of Novel 1", "Genre1 name","Publisher2 Name", 2011
"Title of Novel 2", "Genre1 name","Pulisher1 Name", 2011
Each entity has associated a Stateless EJB that acts as a DAO, using a Transaction Scoped EntityManager. For example:
@Stateless
public class NovelDAO extends AbstractDAO<Novel> {
@PersistenceContext(unitName = "XXX")
private EntityManager em;
protected EntityManager getEntityManager() {
return em;
public NovelDAO() {
super(Novel.class);
//NovelDAO Specific methods
I am interested at when the catalog files are parsed and the corresponding entities are built (I usually read a whole batch of Catalogs at a time).
Being the parsing a String-driven procedure, I don't want to repeat actions like novelDAO.getByName("Title of Novel 1") so I would like to use a centralized cache for mappings of type String-Identifier->Entity object.
Currently I use +3 Objects+:
1) The file parser, which does something like:
final CatalogBuilder catalogBuilder = //JNDI Lookup
//for each file:
String catalogName = parseCatalogName(file);
catalogBuilder.setCatalogName(catalogName);
//For each novel edition
String title= parseNovelTitle();
String genre= parseGenre();
catalogBuilder.addNovelEdition(title, genre, publisher, year);
//End foreach
catalogBuilder.build();
2) The CatalogBuilder is a Stateful EJB which uses the Cache and gets re-initialized every time a new Catalog file is parsed and gets "removed" after a catalog is persisted.
@Stateful
public class CatalogBuilder {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private Cache cache;
private Catalog catalog;
@PostConstruct
public void initialize() {
catalog = new Catalog();
catalog.setNovelsInCatalog(new ArrayList<NovelEdition>());
public void addNovelEdition(String title, String genreStr, String publisher, String year){
Genre genre = cache.findGenreCreateIfAbsent(genreStr);//##
Novel novel = cache.findNovelCreateIfAbsent(title, genre);//##
NovelEdition novEd = new NovelEdition();
novEd.setNovel(novel);
//novEd.set publisher year catalog
catalog.getNovelsInCatalog().add();
public void setCatalogName(String name) {
catalog.setName(name);
@Remove
public void build(){
em.merge(catalog);
3) Finally, the problematic bean: Cache. For CatalogBuilder I used an EXTENDED persistence context (which I need as the Parser executes several succesive transactions) together with a Stateful EJB; but in this case I am not really sure what I need. In fact, the cache:
Should stay in memory until the parser is finished with its job, but not longer (should not be a singleton) as the parsing is just a very particular activity which happens rarely.
Should keep all of the entities in context, and should return managed entities form mehtods marked with ##, otherwise the attempt to persist the catalog should fail (duplicated INSERTs)..
Should use the same persistence context as the CatalogBuilder.
What I have now is :
@Stateful
public class Cache {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private sessionbean.GenreDAO genreDAO;
//DAOs for other cached entities
Map<String, Genre> genreName2Object=new TreeMap<String, Genre>();
@PostConstruct
public void initialize(){
for (Genre g: genreDAO.findAll()) {
genreName2Object.put(g.getName(), em.merge(g));
public Genre findGenreCreateIfAbsent(String genreName){
if (genreName2Object.containsKey(genreName){
return genreName2Object.get(genreName);
Genre g = new Genre();
g.setName();
g.setNovels(new ArrayList<Novel>());
genreDAO.persist(t);
genreName2Object.put(t.getIdentifier(), em.merge(t));
return t;
But honestly I couldn't find a solution which satisfies these 3 points at the same time. For example, using another stateful bean with an extended persistence context (PC) would work for the 1st parsed file, but I have no idea what should happen from the 2nd file on.. Indeed, for the 1st file the PC will be created and propagated from CatalogBuilder to Cache, which will then use the same PC. But after build() returns, the PC of CatalogBuilder should (I guess) be removed and re-created during the succesive parsing, although the PC of Cache should stay "alive": shouldn't in this case an exception being thrown? Another problem is what to do when the Cache bean is passivated. Currently I get the exception:
"passivateEJB(), Exception caught ->
java.io.IOException: java.io.IOException
at com.sun.ejb.base.io.IOUtils.serializeObject(IOUtils.java:101)
at com.sun.ejb.containers.util.cache.LruSessionCache.saveStateToStore(LruSessionCache.java:501)"
Hence, I have no Idea how to implement my cache.. Can you please tell me how would you solve the problem?
Many thanks!
Bye

Hi Chris,
thanks for your reply!
I've tried to add the following into persistence.xml (although I've read that eclipseLink uses L2 cache by default..):
<shared-cache-mode>ALL</shared-cache-mode>
Then I replaced the Cache bean with a stateless bean which has methods like
Genre findGenreCreateIfAbsent(String genreName){
Genre genre = genreDAO.findByName(genreName);
if (genre!=null){
return genre;
genre = //Build new genre object
genreDAO.persist(genre);
return genre;
As far as I undestood, the shared cache should automatically store the genre and avoid querying the DB multiple times for the same genre, but unfortunately this is not the case: if I use a FINE logging level, I see really a lot of SELECT queries, which I didn't see with my "home made" Cache...
I am really confused.. :(
Thanks again for helping + bye

Programatically invalidate/validate cache for specific query
