is it because of studentbean has many fields?
sometimes they give error "containerbackgroundprocessor".
This is happen only while i am updating studentprofile..
What is your JVM heap settings now ?
How much data do you load from the DB?
Try
-Xms 512m -Xmx 1028m -XX:PermSize=128m -XX:MaxPermSize=512m

The goal is to count collection elements without initializing collection. I made it work in some way, but it's not the soulution that I'd say I want.
Back reference is needed because each Price gets some data from Article while being indexed by Hibernate Search.
Join column gives me an option to have only two tables, avoiding 3rd linking table.
#Entity #Indexed
class Article {
String name;
#JsonManagedReference
#OneToMany
#LazyCollection(org.hibernate.annotations.LazyCollectionOption.EXTRA)
#JoinColumn(name = "article_id")
#Field(...bridge = #FieldBridge(impl = PriceBridge.class))
Set<Price> prices;
private User created;
private User updated;
}
#Entity #Indexed
class Price {
#Reference #JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#Field(...bridge = #FieldBridge(impl = PriceArticleBridge.class))
private Article article;
#ManyToOne private Provider provider;
#ManyToOne private CustomCurrency currency;
private BigDecimal amount;
private User created;
private User updated;
}
This setup gives me 2 tables where Price table has article_id and there is no 3rd table for linking purposes. But while loading Article and issuing prices.size(), the whole collection is fetched. This is not good because many other entities are loaded too: Provider from Price and User many times because Provider also has its own 2 properties of User to track creator and updater.
When there is no #JoinColumn, 3rd linking table is created and then it starts to use COUNT() instead of loading the whole collection.
My only question is:
How can I keep only 2 tables and use .size() without loading the whole collection?
SQL example when not having #JoinColumn:
select count(prices_id) from article_prices where article_id =?
SQL example when having #JoinColumn (11 tables joined):

Not sure about your objectives, however sometime following trick could help:
public class Article {
...
Set<Price> prices;
#Formula("select count(*) from price where article_id=:id")
private int priceCount;
public int getPriceCount() {
if (Hibernate.isInitialized(prices)) {
return prices == null ? 0 : prices.size();
}
return priceCount;
}
}
I am doing a dynamic query using Criteria API, the problem I have is that when this query is executed, each query is repeated for each of the records returned by the query (this is shown by the Hibernate console). Then I get very high response times.
My specification class is as follows:
public class PacienteSpecification implements Specification<Paciente> {
private Paciente filter;
public PacienteSpecification(Paciente filter) {
super();
this.filter = filter;
}
public Predicate toPredicate(Root<Paciente> root, CriteriaQuery<?> cq,
CriteriaBuilder cb) {
Predicate p = cb.conjunction();
p.getExpressions().add(cb.equal(root.get("eliminado"), "N"));
if (filter.getNombres() != "") {
p.getExpressions().add(cb.like(cb.upper(root.get("nombres")), "%" + filter.getNombres().toUpperCase() + "%"));
}
if(filter.getApePaterno() != "") {
p.getExpressions().add(cb.or(cb.like(cb.upper(root.get("apePaterno")), "%" + filter.getApePaterno().toUpperCase() + "%")));
}
if(filter.getApeMaterno() != "") {
p.getExpressions().add(cb.or(cb.like(cb.upper(root.get("apeMaterno")), "%" + filter.getApeMaterno().toUpperCase() + "%")));
}
if (filter.getFicha() != "") {
p.getExpressions().add(cb.equal(cb.upper(root.get("ficha")), filter.getFicha()));
}
if(filter.getFechaNacimiento() != null){
p.getExpressions().add(cb.equal(root.get("fechaNacimiento"), filter.getFechaNacimiento()));
}
if(filter.getGenero() != null){
p.getExpressions().add(cb.equal(root.get("genero"), filter.getGenero()));
}
return p;
}
}
My service that calls the repository is as follows:
List<Paciente> listaPacientes = new ArrayList<Paciente>();
Specification<PacienteDoc> pacienteDocEspecificacion = new PacienteDocEspecification(pacBusqueda.getPacienteDocs().get(0));
final List<PacienteDoc> pacDoc = pacienteDocRep.findAll(pacienteDocEspecificacion);
and when making the service call the hibernate console shows me a query for each record:

It seems that Your entity mapping is more or less sth like this:
public class Paciente {
...
#OneToMany(fetch=FetchType.EAGER)
private Set<PacienteDoc> docs = new HashSet<>();
...
}
And then You run into What is the "N+1 selects problem" in ORM (Object-Relational Mapping)?
To fix that simply change #OneToMany(fetch=FetchType.EAGER) to #OneToMany which is equal to #OneToMany(fetch=FetchType.LAZY)
take the following two tables as given:
Objects with columns objId, objTaxonId
Taxa with columns taxId, taxValidSynonymId, taxName (Note Taxa is plural for Taxon)
if a Taxon is valid, its id and validSynonymId are identical, otherwise they are different. To find all synonyms of a Taxon you 'only' need to find all Taxa where the taxValidSynonymId is filled with the taxId of the valid Taxon
how can i gain all Objects where the Taxon has a given Name (including their Synonyms?)
in SQL this is done in a few lines (and Minutes)
SELECT *
FROM Objects
WHERE objTaxonId IN (
SELECT taxId
FROM Taxa
WHERE taxName LIKE 'Test Taxon 1'
OR taxSynIdTaxon IN(
SELECT taxId
FROM Taxa
WHERE taxName LIKE 'Test Taxon 1'
)
)
i was able to work out the inside part, where i gain the list of Taxa and its Synonyms. Now i need to transform this Query to a Subquery...
String NAME_LIKE = "Test Taxon 1";
EntityManager em = EntityManagerProvider.getEntityManager("TestDB"); // get the EntityManager

Query query = em.createQuery(cqObject);
List<TaxonImpl> result = query.getResultList();
NOTE: the Taxon is Mapped as an many to One relation (target-entity is TaxonImpl)
in my actual application the code (from the subquery) will be dynamically, so a Native Query does not help me.
i figured out how to "transform" the subquery into a query but Eclipselink threw me two errors
the first was forbidden access via field, when i tried the in on a result of TaxonImpl (i tried that first, as in my mapping files the Taxon is mapped as Entity.
so after this i tried to form the SQL 1:1 to JPA.
but Eclipselink generated something weird:

this seems strange to me, but it is working - and it is faster than my alternative query, which includes a inner join
NOTE: Eclipselink does ignore the JoinType. regardless what you pass it takes an left outer join. (documentation says something else!)
finally i provide the two examples for join and joinless
private static Predicate addSynonymsWithJoins(Root<BioObjectImpl> r, CriteriaBuilder b, CriteriaQuery cq,
Attribute attr, Path path, Object value) {
Join taxJoin = r.join(BioObjectEnum.taxon.name(), JoinType.INNER);
Path<Object> taxValidSynonymId = taxJoin.get(TaxonEnum.validSynonymId.name());
Subquery<TaxonImpl> innerSubquery = cq.subquery(TaxonImpl.class);
Root fromSubTax = innerSubquery.from(TaxonImpl.class);
innerSubquery.select(fromSubTax.<Integer> get(TaxonEnum.id.name()));
Predicate dynamic1 = cb.like(fromSubTax.get(TaxonEnum.name.name()),
NAME_LIKE);
innerSubquery.where(dynamic1);
Predicate dynamic2 = resolveComparator(b, attr, taxJoin.get(attr.getPropertyName()), attr.getValue());//
Predicate p = b.or(taxValidSynonymId.in(innerSubquery), dynamic2);
return p;
}
private static Predicate addSynonymsWithoutJoins(Root<BioObjectImpl> r, CriteriaBuilder b, CriteriaQuery cq,

I'm stucked with a database problem for several days now. The application hangs after a specific hibernate criteria.list(). Exactly by the following stacktrace:
java.net.SocketInputStream.read(byte[], int, int)
org.postgresql.core.VisibleBufferedInputStream.readMore(int)
org.postgresql.core.VisibleBufferedInputStream.ensureBytes(int)
org.postgresql.core.VisibleBufferedInputStream.read()
org.postgresql.core.PGStream.ReceiveChar()
org.postgresql.core.v3.QueryExecutorImpl.processResults(ResultHandler, int)
org.postgresql.core.v3.QueryExecutorImpl.execute(Query, ParameterList, ResultHandler, int, int, int)
org.postgresql.jdbc2.AbstractJdbc2Statement.execute(Query, ParameterList, int)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(int)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery()
org.hibernate.internal.CriteriaImpl.list()
After some researches and tests I found that the problem is not a blocking query, but a query that is executed forever.
It's a java spring application with the following sessionFactory and transaction manager configuration:
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://localhost:5432/database" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.myapp.domain" />
<property name="configLocation" value="/WEB-INF/hibernate.cfg.xml" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
The underlying database is PostgreSQL and here is the current hibernate configuration
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hbm2ddl.auto">none</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</property>
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="cache.use_query_cache">true</property>
<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.JDBCTransactionFactory</property>
<property name="show_sql">false</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">false</property>
<property name="order_updates">true</property>
</session-factory>
</hibernate-configuration>
The critical area in the code is:
private void fillEmptyNames() throws CablewatchException {
List<Device> devicesList = deviceDao.getDevices();
if (devicesList != null) {
for (Device device : devicesList {
String name = deviceDao.getDeviceName(device.getModule().getObjectIdentifier(), device.getSubrack(), device.getSlot());
...
}
}
}
The application hangs on the second dao function "getDeviceName". which is implemented as follow:
#Transactional(timeout=30)
public String getDeviceName(long moduleId, int subrackNr, int slotNr) throws CablewatchException {
Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Device.class).add(Restrictions.eq("module.objectIdentifier", moduleId)).add(Restrictions.eq("subrack",subrackNr)).add(Restrictions.eq("slot",slotNr)).addOrder(Order.desc("objectIdentifier")).setMaxResults(1);
List<Device> devicesList = criteria.list();
if (devicesList != null && !devicesList.isEmpty() && devicesList.get(0) instanceof Device) {
Device device = devicesList.get(0);
return device.getName();
}
return null;
}
Also a detail I'm confronted with is that the same passage works fine under Windows, so currently the problem is only happening on Linux.

Following the detail about Linux and Windows version, I've tried the same test but instead of the local database postgresql_9.1.13 (Debian) I used a remote access to postgresql_9.3.5(Windows) and installed and tried postgresql_9.1.13(Windows). Both worked correctly.
I also tried the same code from my Windows system to the remote postgresql_9.1.13(Debian) and another machine with a remote postgresql_9.1.15(Debian). In both cases the problem occurs.
It seems the problem could lay on the Linux version of postgresql_9.1.x.
Thanks in advance.
After debugging the database with the commands Craig and Clemens provided me (display current queries, pg_stat_activity, explain analyze select, pg_locks etc.), I found out that it isn't an infinite loop but due to an access for more than 20.000 entries the running time was very long. And due to the ORM layer this time was even extended to exceed several hours. I'm working on a small redesign of the database to optimize this issue.
Thanks guys for the support.
I always get "ArrayIndexOutOfBoundsException" while I query the hive base(both hive-0.11.0 and hive-0.12.0), but sometimes not. Here is the error

Could someone help me?

Sorry, I can't share my samples.
By the way, I've also got this exception before I got "ArrayIndexOutOfBoundException"

Based on the information provided, only this can be a sensible solution to your problem.
I have put the method definition for reference. Please go through it to understand
If you run down the source code closely, there are two areas / possibilities where ArrayIndexOutOfBoundException can be thrown.
Accessing the array values of input splits from Configuration
Reading the Row from currentReadBlock array (this is mostly not the case for the exception since it's size is greater than 0)
Please check your set of input files for job because InputFormat#split() method returns an array of InputSplit type. Each InputSplit is then assigned to an individual Mapper for processing. Mostly, the exception occurs while accessing this InputSplit[] array.
