JPA caching ResultSets
I am experiencing something that make me wonder at JPA.
I write a class that updates the status of a record and immediately query the table for a list that should contain the new updated query, but the list doesn't contain the record.
Secondly, I use a scheduler to update a table and use a reference to obtain my new status, it throws NoResultException.
So, I am asking how does the caching before in JPA supposed to work?
Is it configurable?
Can I remove it completely?
is the JPA implementation specific? That means it Hibernate going to differ from Toplinks in caching behaviour
Please, answers to these question will improve my understanding of this.
Regards
Michael
Greetings Dvohra,
Thank you for you reply, but I have notes Eclipselink manual covers NamedQueries and Queries only in the cache paragraph (I have no direct link right now to this material). Also here are no proofs of that kind Eclipselink could catch calling stored procedures of deleting database records and to make changes in cache needed like
# delete from goods where id > 3 and id < 112;
call delete_goods(3,112);Greetings Konstantin,
Thank you for you reply - I have posted to Eclipse forum, but I still have no luck to get answers.
Best regards,

A error message from running the jpa-cache-server.cmd file
When I try to run jpa-cache-server.cmd file, it show the following error message:
"failed to load main-class manifest attribute from %coherence_home%\lib\coherence-jpa.jar"
What is the problem?Forgive me but I do not see that file (jpa-cache-server.cmd) in the Coherence 3.5 distribution. With that said, I don't believe that coherence-jpa.jar is a executable jar. What exactly are you trying to do?
If you are trying to start a cache server with the jpa classes available to it I would suggest just adding the coherence-jpa.jar to the class path.

How to refresh JPA cache from non-JPA code(JDBC)
In the system, let say there are two different tools are available, Tool-A_Uses_JPA and Tool_B_Uses_JDBC.
As the name of tools is self explanatory what persistence technology used by tools.
Say,there is a table COMMON_TABLE. This can be used by both tools to perform CRUD operation.
Lets see the problematic scenario-
Tool_B_Uses_JDBC tries to insert some new rows in COMMON_TABLE, by performing following tasks--
(Tool_B_Uses_JDBC already calculated how many rows will be inserted into COMMON_TABLE. Let's say it is 5.)
1. Read JPA_GENERATED_KEYS table for getting last_value for COMMON_TABLE. Let's say it is 30.
2. Add (last_value + number of rows to be inserted), here it 30+5 =35.
3. Update the JPA_GENERATED_KEYS table for last_value of COMMON_TABLE by the value calculated in step 2.
In my example it was updated by 35.
Above three steps done in a single transaction.
Now, ideally if any other tool use this COMMON_TABLE to perform any insert operation, the last_value from
JPA_GENERATED_KEYS should be 35. But for Tool-A_Uses_JPA, JPA cache is enabled. So this tool still get
last_value as 30, rather 35. And hence Tool-A_Uses_JPA, does not work properly.
So to resolve this issue, i thought to write a code to update JPA cache while updating the last_value.
Is there any way to update and/or send notification to all other tools to update JPA cache when updating
last_value form NON_JPA code?
Or is there any other way to resolve this issues?
Thanks.Marking this as answered, as this can never be a situation the way JPA uses caching. This was issue with the transaction form non-JPA code. Actually when JDBC uses data source then whether transaction will be committed as soon as application issues commit, is not guaranteed. Hence need to work on transaction.

Greetings,
Could somebody help me to find answer does EclipseLink JPA implementation NativeQuery cache results of stored procedure execuing like
call get_entities(2,3,2);Is here some way to have stored procedures excection result cached with JPA otherwise?
Greatest thanks in advance,Greetings Dvohra,

Command Execution fails only under heavy load and JPA cache store.
Using...
Coherence: 3.5.2
Commad Pattern: 2.5.0
I have a servlet that simply creates a simple POJO puts in the cache and then fires off a command that does additional formatting to the POJO.
With JDBC cachestore I have no problem. It works fine.
With JPA I get the bellow exception under heavy load only. I.e: If I send one-two requests. Everything works fine and my data is present in the database after 30 second write-behind. Once I bump up to 200 users I get the exception.
I figure I'm running out of memory on the cache because of JPA enitites take more resources?

Edited by: user12249856 on Jan 21, 2010 10:15 AMDone look at the original thread logs are below... I'm thinking that the key is no longer in the cache at the point the processor fires?
I can also assure you that there is only to instance of coherence running
1- The actual cache server node
2- The client, set to localstorage = false
I ensure the cache server starts and then I start the client.

Start a JPA persistent cache server but it is hanging
I create a JPA persistence project and online EJB object HR.EMPLOYEES according to the guide of Chapter 6 of
Tutorial for Oracle Coherence (3.5). But when I tried to start a JPA persistent cache server, it is hanging and report
the following message:

Need Clarification on using cache along with JPA
Hi,
I am using Oracle Coherence 3.5 and Jdeveloper 11g.
I have written a sample program which implements CacheStore which performs the following operations:
Insert, Update, Delete
Configured cache-config.xml file in whcih the element cachestore-scheme is used to invoke the corressponding class and the table name.
When I tried to run the cache using the JPA-Cache-server.bat I got the values accordingly. But each and every time the data is fetched from Database. I am using distributed-scheme in the configuration file. How do I configure the file such that for the first time the values comes form DB and then next time I get values from cache.
I used the same cache name in another program and tried to retrieve the values from cache but i got only null values:(
I will be very thank full to you if any one helps me on this.
Waiting for ur response..
Thanks,

Entity-Named Query Caching - Need live results from DB not Cached
I've developed an application EJB3 web application which uses Entity Beans and NamedQueries to retrieve my results.
Aswell as my main EJB3 web application I also have an external interface (Oracle Stored Procedure) which is updating data in my database tables. The problem is that the when the NamedQueries are called they only bring back "Cached" resultsets and not the live results that exists in the database at that time. If my Stored Procedure updates a value (or if I update a value via Toad for testing) the NamedQuery does not bring back these changes. From what I have read about NamedQueries it seems that they do actually query the live db but send back the cached values for performance reasons.
Is there a way to turn off caching of Query results?
If not is there another way to deal with this issue?
ps. I'm using Jdev 10.1.3.4 and appserver 10.1.3.1Anyone?

Hi All,
In Hibernate we can see the query by setting in persistence xml file
<property name="show_sql">true</property>
Do we have anything like this in SAP JPA so that i can see the actual query ?
If not is there any place in Server where can I check the fired query?
Many ThanksHi Arvind,
You can monitor JPA Cache, for more details please have look of the below help

WLS9.2 caching results of CallableStatement?
Hello All,
I've been flummoxed by a problem in which the results of a CallableStatement seem to be cached by our WebLogic 9.2 server. We have a connection pooled DataSource talking to Oracle8i (8.1.7.4.0), configured with 10 statements in a cache and the LRU algorithm, also 1 connection initially and a maximum of 15. We're using Oracle's ojdbc14.jar implementation and orai18n.jar.
We're mostly executing CallableStatments for packaged procedures/functions that in turn call other procedures or run selects. What I'm geting at is, we're retrieving data rather than updating through our CallableStatement. The retreieved data we extract from the returned oracle ARRAY type using a homegrown map to the "shape" of each Struct underlying the ARRAY collection. In this problem, two CallableStatements are run and return data to our Java app, and at the start all is well. Then the underlying data is changed - via procedures in an oracle forms app on the database, not our Java app. Our Java app should display the changed data. The first CallableStatement runs again and an Eclipse remote debug shows the updated data, however the second CallableStatement continues to return the older data. We have oracle test harnesses that call the same procedures as our CallableStatements; both return the new data. If we leave it for sometime less than 45 minutes, the new data is then returned by both statements. Similarly, if we set the statement cache size to 0, the newe data is returned both times. We're closing the DB resources, (and in the right order: ResultSet, Statement and Connection)
Has anyone come across this issue before? (From my searches it appears not). Secondly, is there a way of debugging into the WLS DataSource mechanism? I can go down as far as getting the ARRAY and no further, but if there's a switch/command line arg that I could use in the startWeblogic script that'd be great. I remember reading about a WebLogic attributeSpy, (or maybe spyAttribute?) and if I had to try the WLS driver for that I'd give it a go, but if Oracle have something similar that'd be fantastic.
FWIW, changing the data via the oracle forms app changes the sysdate on the oracle database too.
Variables from the debug that might be relevant:
DataSource retrieved from jndi context of type WLEventContextImpl
driversettings
weblogic.jdbc.rmi.internal.RmiDriverSettings{verbose=false chunkSize=256 rowCacheSize=0}
driverProps entrySet [EmulateTwoPhaseCommit=false, connectionPoolID=xxxxx, jdbcTxDataSource=true, LoggingLastResource=false, dataSourceName=xxxxx]
Connection is PoolConnection_oracle_jdbc_driver_T4CConnection
weblogic.jdbc.wrapper.PoolConnection_oracle_jdbc_driver_T4CConnection@5f1
statement is CallableStatement_oracle_jdbc_driver_T4CCallableStatement (id=nnnnn)
weblogic.jdbc.wrapper.CallableStatement_oracle_jdbc_driver_T4CCallableStatement@5f2
There is a StatementHolder too:
weblogic.jdbc.wrapper.CallableStatement_oracle_jdbc_driver_T4CCallableStatement@5f2=weblogic.jdbc.common.internal.StatementHolder@21cae26
In the "stmts" table in "conn" in "stmt", there are the following two variables:
jstmt T4CCallableStatement (id=nnnnn) oracle.jdbc.driver.T4CCallableStatement@21cad44
key StatementCacheKey (id=nnnn) { call my_pack_name.my_proc_name(?,?)}:true:-1:-1
Thanks for any help that anyone might be able to shed on this!
Best Regards,
ConorDHi Joe,
Thanks for your reply; I'm delighted to see that you're still here helping WLS users under the Oracle banner :-)
To answer your question, yes, we do get good behaviour when we set the statement cache size to 0. I ran a test on that where I set the Statement cache size to 0 and the initial number of connections to 0, then:
*1)* Logged in through our Java/WLS app to a few test scenarios and saw the data
*2)* Ran the oracle app on that DB outside of WLS which moved forward the state of the app, including sysdate
*3)* Logged in again through our Java/WLS app to the test scenarios and saw the new data being returned from both CallableStatements
I don't think that the initial number of connections had any effect on this, since WLS was running all the time and there was no retargetting of the DataSource, so IMHO it must have been the statement cache size.
Where we hadn't got the Statement cache size 0, for step *3)* above one of the two CallableStatements continued to return the old data, (as if it had been told by the DB that the result hadn't changed, and it might as well return a cached result - if WLS does cache ResultSets?)
Lastly, there is one case where we do see good behaviour even with a Statement cache size of 10:
Between steps *2)* and *3)* above, if I untarget & activate, then retarget & activate the DataSource (to the same server/db that had just been untargetted) we see new data back from both statements on running step *3)*, even with the Statement cache size set to 10. My guess is that the untarget frees up any object in the Statement cache for collection and removes the remote DB session stubs that may be caching on the DB side.
Thanks again and Best Regards,

ThanksWhat's happening is the JPA cache store is failing on creation/initialization due to its inability to connect to the database.
Can you describe the behaviour you're expecting? Are you saying you want an "optional" cache store that works when the database is up and silently ignores problems when the database is down? It would still have to fail on write otherwise Coherence write behind will believe the writes have been successfully performed and won't get retried. On a get() with a cache miss, would retuning a null from the cache store be what you want? Your application will be lead to believe that there is no object with the specified key when in reality there may be such an object that just doesn't happen to have been read into cache yet. Perhaps this is acceptable if you were to fully warm your caches.

Getting following exception while running coherence tutorial using JDev
Hi,
I am getting following exception while running the Oracle Coherence tutorial in Jdeveloper, but unfortunately I'm not able to figure out what's wrong with my configuration.

ZiaHi Zia,
The error is...
Caused by: java.io.InvalidClassException: org.eclipse.persistence.indirection.IndirectList; local class incompatible: stream classdesc serialVersionUID = 4038061360325736360, local class serialVersionUID = -494763524358427112
...which means you have two different versions of org.eclipse.persistence.indirection.IndirectList, one on the server and one in the client (JDeveloper). As these classes have different serialVersionUID values then Java throws an exception when deserializing as they are probably not compatible.
I don't know much about the Eclipse stuff but from looking at your post I can only assume one version of the class is in D:\Coherence\toplink\jlib\eclipselink.jar on the Coherence server side and the other is in JDevloper in D:\OracleSOA\Middleware\modules\org.eclipse.persistence_1.1.0.0_2-1.jar as these are the only jar file containing "eclipse" that I can see on the classpaths.
