Konfigurieren von Tomcat Connection Pooling ohne Verwendung von JNDI

Question

Ich bin neu in der Verbindungspooling-Technik und im Tomcat Official Guide für den Tomcat JDBC-Verbindungspool gibt es eine Option zum Initialisieren von Pooling nach Plain Java Class durch Initialisierung der Data Source-Klasse. Aber wenn ich versuche, dasselbe zu implementieren, gibt es mir ständig die Ausnahme. Meine URL ist korrekt.

Kann jemand verstehen, was alles erforderlich ist, um Connection Pooling mit Pool Properties einzurichten?

String dburl="jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=hostname) (PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=shostname2)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=Service)))"; 

p.setUrl(dburl); 
p.setDriverClassName("oracle.jdbc.OracleDriver"); 
p.setUsername(username); 
p.setPassword(pwd); 
p.setJmxEnabled(true); 
p.setTestWhileIdle(false); 
p.setTestOnBorrow(true); 
p.setValidationQuery("SELECT 1 from dual"); 
p.setTestOnReturn(false); 
p.setValidationInterval(30000); 
p.setTimeBetweenEvictionRunsMillis(30000); 
p.setMaxActive(100); 
p.setInitialSize(10); 
p.setMaxWait(10000); 
p.setRemoveAbandonedTimeout(600); 
p.setMinEvictableIdleTimeMillis(30000); 
p.setMinIdle(10); 
p.setLogAbandoned(true); 

p.setRemoveAbandoned(true); 
p.setJdbcInterceptors(
     "org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;" 
     + "org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;" 
     + "org.apache.tomcat.jdbc.pool.interceptor.ResetAbandonedTimer"); 

p.setLogValidationErrors(true); datasource = new org.apache.tomcat.jdbc.pool.DataSource(); 
datasource.setPoolProperties(p);

Answer 1

dieses Problem aufgrund oracle.jdbc Treiber auftreten Sie p.setDriverClassName("oracle.jdbc.driver.OracleDriver"); anstelle von p.setDriverClassName("oracle.jdbc.OracleDriver");
