Problem in continuous query cache with PofExtractor
Hi,
I am creating a CQC with a filter having PofExtractor. When I try to insert any record in cache it is giving me exception at server side.
When I do not use PofExtractor it is working fine.
If any one know about this prblem please help.
I am using C# as my client application

Hi JK,
I have made some changes in my server. Now I am not using any pof definition on server side. I think that's why it is giving me the error.

Continuous Query Cache Local caching meaning
Hi,
I'm enconter following problem when I was working with continuous query cache with local caching TRUE.
I was able to insert data into coherence cache and read as well.
Then I stopped the process and try to read the data in the cache for keys which I inserted earlier.
But I received NULL as the result.
NamedCache::Handle hCache = DerivedCQC::create(CacheFactory::getCache("dist-AccountGCE"), AlwaysFilter::getInstance(), true);

return m_hMapLocal->containsKey(vKey);

When I switch off the local storage flag to FALSE.
I was able to read the data.
NamedCache::Handle hCache = DerivedCQC::create(CacheFactory::getCache("dist-AccountGCE"), AlwaysFilter::getInstance(), false);
Ideally I'm expecting in true scenario when I'm connected with coherence all keys and values with locally synced up with cache and store it locally and for each update also it will get synched up.
In false scenario it will hook into the coherence cache and read it from their for each key and cache values from that moment onwards. Please share how it is implemented underneath
Thanks and regards,
SuraHi Wei,
I found the issue when you declare you cache as an global variable then you won't get data in TRUE scenario and if you declare the cache during a method then you will retrieve data.
Try this.......
#include <iostream>
#include <coherence/net/CacheFactory.hpp>
#include "coherence/lang.ns"
#include <coherence/net/NamedCache.hpp>
#include <stdio.h>
#include <stdlib.h>

#include <coherence/stl/boxing_map.hpp>
#include "EventPrinter.hpp"
using namespace coherence::lang;
using coherence::net::CacheFactory;

using coherence::net::ConcurrentMap;
using coherence::net::cache::ContinuousQueryCache;
using coherence::util::filter::AlwaysFilter;
using coherence::util::filter::EntryFilter;
using coherence::util::Set;
using coherence::util::Iterator;
using coherence::stl::boxing_map;
NamedCache::Handle hCache = DerivedCQC::create(CacheFactory::getCache("gce-Account"), AlwaysFilter::getInstance(), true);
int main(int argc, char** argv) {
std::cout << "size: " << hCache->size() << std::endl;
in above example you will see size is 0 for true case and size is equal to data size in the cache in false scenario.
But if you declare the cache as below you will get the expected results as the documentation.
int main(int argc, char** argv) {
NamedCache::Handle hCache = DerivedCQC::create(CacheFactory::getCache("gce-Account"), AlwaysFilter::getInstance(), true);
std::cout << "size: " << hCache->size() << std::endl;
Is this a bug or is this the expected behaviour. According to my understanding this is a bug?

Missed and duplicate events with Continues Query Cache
We have seen missed events and duplicate events when we register to receive events (using Continues Query Cache) on an entry in the cache while the entry is updating.
Use case:
Start a Node
Start a Proxy
Start Extend Client
Implementation of the Extend Client
Create Cache
Add Entry to Cache
Initiate Thread 1 {
For each ( 1 to 30)
Run Update Entry Processor on cache entry; Entry Processor increments the Cache Entry value by 1
Initiate Thread 2 {
wait until Cache entry is updated 10 times
Create MAP Listener {
For Entry Insert Event {
Print event
set Initial value = new value
For Entry Update Event {
Print event
set Update value = + 1
Initiate Continues Query Cache (cache, Always Filter, MAP Listener)
Start Thread 1
Start Thread 2
Waits until Thread 1 and Thread2 are terminated
Expected Result = read the value of the entry from cache
Actual result = Initial value + Update value
Results we have seen in two tests_
Test1: Expected Result > Actual results: Missing events
Entry Inserted Event: MapEvent{ContinuousQueryCache inserted: key=1, value=UpdateObject [intNumber=1, longNumber=13]}

Continuous Query Caching - Expensive?
Hello,
I have had a look at the documentation but I still cannot find a reasonable answer to the following question : How expensive are continuous query caches?
Is it appropriate to have many of them?
Is the following example an acceptable usage of Continuous query caching (does it scale?)
In the context of a web application:
User logs onto a website
User performs a "Search" for financial instruments
A continuous query cache is created with a filter for those instruments returned (say, 50) to listen to price updates.
If the user pages, or does another search, the query cache is released and a new one, with an updated filter, is created.
Does it make a difference if we are using the extend client?Hi,
So 100 CQCs is probably not too excessive depending on the configuration of the process instantiating the CQCs and the cluster size etc.
Each CQC will hold its own set of deserialized keys and values, so yes they are distinct objects, although a CQC of 50 entries would not be very big.
One query I have - you mention that this is a Web Application but you also mention an Extend Client. Is your Web App and Extend Client of the main cluster? Is there are reason why you did this, most people would make a Web App a storage disabled cluster member so it would perform a bit better. Providing the Web App sits on a server that is very close in network terms to the cluster (i.e. same switch) then I would make it part of the cluster - or is the Web App the thing that is in the "regional environment".
If you are running CQCs over Extend then there used to be some issues with this if the Extend connection was lost. AFAIK this is supposed to be fixed in later patches so I would get 3.7.1.8 and make sure you test that the Web App continues to work and properly fails over if you kill its Extend connection. When the CQC fails over it will reinitialize all its data so you will need to cope with that if you are pushing changes based on the CQC.

Empty query cache with ABAP code
Hi Experts,
Is there any way to empty the query cache using ABAP code?
Thank you!
Regards,
SamSam,
You can clear cache by using transaction RSRCACHE. Also, you can use a BDC ABAP program to do it.

Querying cache with data that is large enough to fit into available memory
Query on a cache would be applicable on the data that can fit into the cache storage as per the link http://coherence.oracle.com/display/COH35UG/Query+the+Cache. However there is also a mention about restricting the cache content along a specific dimension, so that the query actually knows what to expect from the cache.
Generally any enterprise application would generate huge amount of data and practically it would be difficult to set the fix up the limit to a specific dimension. Fixing the limit is to decide on what else has to be taken from the persistent store.
Please let me know if there are best practices defined in this regard?
Edited by: Mahesh Kamath on Feb 5, 2010 3:16 AMHi,
Thanks for the clarification.
Okay. So in a nutshell it sounds like you have data spanning a memory cache and living in a database and
you want to be able to query the entire dataset, so you need someway to figure out what
is in the cache and what is in the database?
In general queries in Coherence only work against the cached data, and because of the LRU characteristics
of memory caches its going to be really difficult to know at a point in time what set of information is living
in memory and which has been evicted and persisted in the underlying database. If the dataset that spills
over into a database is fringe (i.e. a small percentage of your total data), then the simplest solution is to
add new cache servers to get you out of this problem (i.e. avoid databases). If the cache is just the tip
of the iceberg of all your data than you probably want to have either a write-through or write-behind
configuration and query the database directly (write-through will get you everything you put into a cache,
while write-behind will get everything except for the most recent puts which are working their way to being written in batch).
My guess is that retrieval of keys out of the database, and then retrieval of data through the cache using
the keys would not be a good idea. For one thing if the database is substantially larger than the cache,
the entire cache will get evicted by the query activity, which generally is a bad idea. More importantly the
code path to get the data will be much longer and would result in N number of invocations of SQL as opposed
to a single invocation of SQL with a cursor.

Is a continuous query aggregator possible?
How can I make something like this a continuous query so I'm constantly aware of the count of working Orders in the orderCache?
Filter f2 = new EqualsFilter("isWorking", true);
Integer workingOrdersCount = (Integer)orderCache.aggregate(f2, new com.tangosol.util.aggregator.Count() );Thanks,
AndrewHi Andrew,
We do not have a continuous aggregator at this time. The specific use case you suggest could be accomplished by maintaining a continuous query cache (CQC) and calling it's size() method. The resource consumption of the CQC can be kept to a minimum by configuring it to only cache the matching keys, and to not hold the values.
thanks,

Issues with Query Caching in MII
Hi All,
I am facing a strange problem with Query caching in MII query. Have created one xacute query and set cache duration 30 sec. The associated BLS with the query retrieves data from SAP system. In the web page this value is populated by executing an iCommand. Followings are the steps I followed -
Query executed for first time, it retrives data from SAP correctly. Lets say value is val1
At 10th sec Value in SAP changed to val2 from val1.
Query excuted at 15th sec, it gives value as val1. Which is expected as it gives from cache.
Query is executed 1t 35th sec, it gives value as val2 retriving from SAP system. Which is correct.
Query executed at 40th sec, it gives value as val1 from cache. Which is not expected.
I have tried with java cache clear in browser and JCo cache of the server.
Same problem I have seen for tag query also..
MII Version - 12.0.6 Build(12)
Any thoughts on this.
Thanks,
SoumenSoumen Mondal,
If you are facing this problem from the same client PC and in the same session, it's very strange.. but if there are two sessions running on the same PC this kind of issue may come..
Something about caching:
To decide whether to cache a query or not, consider the number of times you intend to run the query in a minute. For data changing in seconds, and queried in minutes, I would recommend not to cache query at all.
I may give a typical example for query caching in a query on material master cached for 24 hours, where we know that after creating material master, we are not creating a PO on the same day.

Query performance problem - events 2505-read cache and 2510-write cache
Hi,
I am experiencing severe performance problems with a query, specifically with events 2505 (Read Cache) and 2510 (Write Cache) which went up to 11000 seconds on some executions. Data Manager (400 s), OLAP data selection (90 s) and OLAP user exit (250 s) are other the other event with noticeable times. All other events are very quick.
The query settings (RSRT) are
persistent cache across each app server -> cluster table,
update cache in delta process is checked ->group on infoprovider type
use cache despite virtual characteristics/key figs checked (one info-cube has1 virtual key figure which should have a static result for a day)
=>Do you know how I can get more details than what's in 0TCT_C02 to break down the read and write cache events time or do you have any recommandation?
I have checked and no dataloads were in progres on the info-providers and no master data loads (change run). Overall system performance was acceptable for other queries.
ThanksHi,
Looks like you're using BDB, not BDB JE, and this is the BDB JE forum. Could you please repost here?:

oForm.DataSources.DataTables.Item(0).ExecuteQuery("DELETE FROM rptReport")
Catch ex As Exception
End Try
oForm.DataSources.DataTables.Add("TestReport")
oForm.DataSources.DataTables.Item(0).ExecuteQuery("SELECT Number, RefDate, Memo into rptReport FROM dbo.OJDT")
oTable = oForm.DataSources.DataTables.Item("TestReport")
This code is error. I don't know how to execute 2 this sql command. Hope everyone help me hix hix! ./Invalid query tree [300-33]. The SQL error is 8180/
But search in SQL book hasn't got that err. Some person spoke ExecuteQuery property wasn't support Table Delete and Create, it only support simple Select... I tried to use Recordset but don't success. Can I use "Delete" and "Select ... Into..." query another style??? Help me, please...!!! -
Problem in SAP Query with currency conversion based on table TCURX
Hi All,
I have an infoset where tables A903 and KONP are joined . Query is displaying the KONP-KBTER values with currency as stored in the database table .My requirement is to show the KBETR value as per decimals stored in TCURX table for that currency .
For Example If KONP-KBETR = 51.29 JPY , It sholuld display as 5129 as Decimal places for JPY is 0.
There is FM CURRENCY_AMOUNT_SAP_TO_DISPLAY Which gives the equvivalent display value to the databse value value.But it is giving dump because of type conflict with
KONP-KBETR .
Can any body help me how can i solve the problem in My Query ? .Pls any small idea taht may help greatly also warmly welcome .
Thx,
Dharma .Hi Sriram ,
But how can i use it in Queries . I mean should I go for a additional filed in infoset and then passing the converted value to the the that additional field .
Thx ,

Query Performance with and without cache
Hi Experts
I have a query that takes 50 seconds to execute without any caching or precalculation.
Once I have run the query in the Portal, any subsequent execution takes about 8 seconds.
I assumed that this was to do with the cache, so I went into RSRT and deleted the Main Memory Cache and the Blob cache, where my queries seemed to be.
I ran the query again and it took 8 seconds.
Does the query cache somewhere else? Maybe on the portal? or on the users local cache? Does anyone have any idea of why the reports are still fast, even though the cache is deleted?
Forum points always awarded for helpful answers!!
Many thanks!
DaveHi,
Cached data automatically becomes invalid whenever data in the InfoCube is loaded or purged and when a query is changed or regenerated. Once cached data becomes invalid, the system reverts to the fact table or associated aggregate to pull data for the query You can see the cache settings for all queries in your system using transaction SE16 to view table RSRREPDIR . The CACHEMODE field shows the settings of the individual queries. The numbers in this field correspond to the cache mode settings above.
To set the cache mode on the InfoCube, follow the path Business Information Warehouse Implementation Guide (IMG)>Reporting-Relevant Settings>General Reporting Settings>Global Cache Settings or use transaction SPRO . Setting the cache mode at the InfoCube level establishes a default for each query created from that specific InfoCube. -
