[JBoss-user] Handling Database failures
Hi, I have recently deployed a system in production (Jboss 3.2.3), and the Database (server) that is being used is less than reliable, and often goes offline without warning. When the DB goes offline, a couple of things happen to my system. Firstly, I get MB of stack traces in the log which consist of lots of 2004-02-11 12:12:08,236 ERROR [org.jboss.resource.adapter.jdbc.PreparedStatementCache] Failed closing cached statement ..stack trace... ..is there anyway to prevent these, apart from not using the PreparedStatementCache. The second issue is a bit more of an issue. I use COMMIT OPTION A, and once the DB is back up and running, I get various problems when I think Jboss is trying to get an Object from the cache - javax.ejb.ObjectNotFoundException: No such entity! at org.jboss.ejb.plugins.cmp.jdbc.JDBCFindEntityCommand.execute(JDBCFindEntityC ommand.java:52) at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.findEntity(JDBCStoreManager. java:571) at org.jboss.ejb.plugins.CMPPersistenceManager.findEntity(CMPPersistenceManager .java:299) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.findEntity( CachedConnectionInterceptor.java:300) at org.jboss.ejb.EntityContainer.findLocal(EntityContainer.java:637) at sun.reflect.GeneratedMethodAccessor80.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.ejb.EntityContainer$ContainerInterceptor.invokeHome(EntityContaine r.java:1043) at org.jboss.ejb.plugins.AbstractInterceptor.invokeHome(AbstractInterceptor.jav a:88) at org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invokeHome(EntitySync hronizationInterceptor.java:197) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invokeHome( CachedConnectionInterceptor.java:214) at org.jboss.ejb.plugins.AbstractInterceptor.invokeHome(AbstractInterceptor.jav a:88) at org.jboss.ejb.plugins.EntityInstanceInterceptor.invokeHome(EntityInstanceInt erceptor.java:89) at org.jboss.ejb.plugins.EntityLockInterceptor.invokeHome(EntityLockInterceptor .java:61) at org.jboss.ejb.plugins.EntityCreationInterceptor.invokeHome(EntityCreationInt erceptor.java:28) at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor .java:88) at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT. java:267) at org.jboss.ejb.plugins.TxInterceptorCMT.invokeHome(TxInterceptorCMT.java:98) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.jav a:92) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:120) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryF inderInterceptor.java:93) at org.jboss.ejb.EntityContainer.internalInvokeHome(EntityContainer.java:483) at org.jboss.ejb.Container.invoke(Container.java:720) at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.invokeHome(BaseLocalProxyF actory.java:293) at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:110) at $Proxy69.findByPrimaryKey(Unknown Source) -- ...the object does exist in the DB, but looking through the logs Jboss does not seem to be getting as far as issuing any SQL.

As Commit option A is giving me a massive performance boost in this part of the system, I am am trying to think of workarounds. What if, instead of deleting the 'item', I set a 'deleted flag' to true in the ItemEJB, and change the Order.getItems() to Order.getUnDeletedItems(), would that work, or would I just get items in the second 'collection' that have had their deleted flag set by the first client?

Just to make sure I understand, with Commit A the finder is querying the DB,
which contains a 'record' that has been deleted from the cache, but not from
the DB, and when I am doing the iteration the entity has already been deleted
from the cache and I get the (uncatchable) NoSuchObjectLocalException?
If so, is not Commit option A dangerous, ith something beaing read from the
(up to date) cache, and others being read from the (out of date) DB?

I understand how this works, because everything is read from the same place

So basically, from what I understand, is Commit Option A has problems if you
are deleting 'records'? I am not sure that is right?

[JBoss-user] Caching issue?
Hi,
I have an issue that I want to understand before I try and fix it...
JBoss 3.2.2, Commit Option A...
I have a SLSB method something like...
public void doSomething(){
Collection c = OrdersEJB.getItems();
}
If these method is called at the same time by two different clients, the
first one works the second gives me an error because the OrdersEJB.getItems()
returns a collection that includes the 'item' that has already been deleted
by the first client, and I try to use it. Part of the stack trace

I do have some, but the realmproblem was I was using the 'Instance per Transaction' container config, whch does not seem to support commit option A. The only reason I was using the Instance per Transaction' container config, was that I was getting a lot of deadlocks when two transactions were 'reading' the same instance of an entity bean.

[JBoss-user] Commit Option Confusion
Hi, I am tuning an app before deployment on 3.2.2. As this app 'owns' its own database and the DB is not that quick, I though that changing from the default commit option B to A should give me some improvements, but seems to make no difference. My tests complete in the same time with both option A and B, the SQL generated is identical with both options, and the CacheSize settings for the EJB's in the jmx-console are always Zero. I am missing something or is my understanding of Commit options flawed?

Don't you think so? No. Beacuse the detail tables are listed in the FROM clause of the SQL, the Joins should always be done or all records from the detail tables will be returned regardless of if they have a 'match' in the master table or not. > > SELECT OBJECT(O) from Customer WHERE (o.id = ?1 OR o.contact.surname = > > ?2) > > > > Customer ID Customer.ContactID Contact.ID Surname > > 1 2 1 smith > > 1 2 2 blogs > > 1 2 3 dow > > > > ..becase there is no surname match for "fleury", it returns all contacts > > Yes.

In this case the detail tables are vehicle and contact, each contain many
records, but only one is 'linked' to the master record

Correct

> ?3)"
> Do I understand you right?
No. Your interpretation is correct, the problem is is that the SQL generated
only does the 'join' with the detail tables if, say contact.surnameUpper
equals the parameter supplied, if not it returns all records from the contact
table, even though only one has a releationship with 'o'.
OK, here is a simple example, imagine these two DB tables
create table Customer (
ID Integer,
Contact_ID Integer
)
create table Contact (
ID Integer,
Surname Varchar(50)
)
..which results in two ejb's..
Contact {
public Integer getID();
public void setID(Integer id);
public String getSurname();
public void setSurname(String surname);
}
..Customer {
public Integer getID();
public void setID(Integer id);
public Contact getContact();
public void setContact(Contact contact);
}
If I want to write a finder for Customer that returns all Customers that
match a given ID or given Surname, I would write something like..
SELECT OBJECT(O) from Customer WHERE (o.id = ?1 OR o.contact.surname = ?2)
Jboss 3.0.8 will generate SQL something like...
SELECT cus.ID
FROM Customer cus, Contact con
WHERE
(cus.ID = ? OR con.surname = ?)
AND
(cus.ContactID=con.ID)
Which will return all records where Customer.ID = parameter supplied or
Contact.Surname = parameter supplied AND Contact.ID = Customer.ContactID.
Jboss 3.2.2 will generate SQL something like...
SELECT cus.ID
FROM Customer cus, Contact con
WHERE
cus.ID = ? OR (con.surname = ? AND cus.ContactID=con.ID)
Which will return all records where Customer.ID = parameter supplied or
Contact.Surname = parameter supplied AND Contact.ID = Customer.ContactID OR
all contacts where Contact.Surname != parameter supplied.
To make it clear, if the data in the tables was
Insert into customer (id, contactid) values (1, 2)
Insert into contacts (id, surname) values (1, "smith")
Insert into contacts (id, surname) values (2, "blogs")
Insert into contacts (id, surname) values (3, "dow")
If I passed customer.id = 1 and surname="fleury" to the finder above..
Jboss 3.0.8 will return
Customer ID Customer.ContactID Contact.ID Surname
1 2 2 blogs
Jboss 3.2.2 will return
Customer ID Customer.ContactID Contact.ID Surname
1 2 1 smith
1 2 2 blogs
1 2 3 dow
..becase there is no surname match for "fleury", it returns all contacts
I hope I am missing something simple, but I have a number of these type of
queries, all work fine under JBoss 3.2.2 and another app server, none work
correctly under 3.2.2

AND (t0_o.VEHICLE_ID=t2_o_vehicle.ID AND t0_o.CONTACT_ID=t1_o_contact.ID AND t0_o.ADDRESS_ID=t3_o_address.ID) ..which is correct, but Jboss 3.2.2 generates the following SQL...

[JBoss-user] Handling Deadlocks
Hi, I have a method in a stateless session bean that basically gets a list of entity beans, and does something with the first one in the list. If two clients call this method at the same time, the one that calls the method 'last', gets an Application deadlock as they have both got the same entiy bean from the top of the list, which is fine, and something I expect to happen. What I then want to do is to (in the second transaction) is to then get the next bean from the list instead. Unfortunatly, although I capture the deadlock exception, and get the next bean, the transaction has been 'marked for rollback', so my code always fails. What is the best way to handle this situation?

Just to add another comment to the list... I am a user of Jboss, it is one tool in my toolbox of many. I have read the getting started stuff, and have bought the pay-for docs, but IMO, there is a big gap in the middle.The getting started stuff from JBoss and third-parties, by its nature is 'simple', but does tend to spend too much time on 'EJB' development and third party tools (xDoclet, ANT etc.), neither of which I am really interested in as there are plenty of docs/books/howtos on that sort of stuff available elsewhere. The advanced pay-for docs, are arguably the best docs going for any appserver, but as a user of the 'product', I am not interested in how the product was developed, and how great the arcitecture is, I just want to use the thing. What is missing is a good old fasioned user manual, you know, the book that tells you what buttons to press and what knobs to tweek. To put it another way, when I buy a word processor, I don't need the getting started document that teaches me how to type, nor do I need the advanced documentation that explains the word precessors internals and source code, I just need a user manual that tells me what it does and how to do it.

Hi, Just entering the merry world of JBoss, mainly for learning and enjoyment. I have Jboss 2.4 installed and running and I have ordered the Jboss 'Book'.
