我使用Spring和Hibernate ，我使用Oracle 11g作為數據庫，我使用JBoss 5 。
我在自動重新建立連接時遇到問題
我使用c3p0-0.9.1.1.jar
這是我的應用程序中的配置：

我的應用程序使用以前的數據庫配置正常工作，但我的問題是當我與我的應用程序（超過 200 個用戶）有很多連接時出現錯誤，這就是我使用連接池的原因。
當我在服務器中出現此錯誤時，oracle 服務可以正常工作，因為我可以直接在數據庫中執行查詢。 只是問題出在我部署在 jboss 和 oracle 中的應用程序的連接之間
在_BaseRootDAO.java我有這個方法：
/**
* Return a new Session object that must be closed when the work has been completed.
* @return the active Session
*/
public Session getSession() {
return getSession(
getConfigurationFileName());
}
/**
* Return a new Session object that must be closed when the work has been completed.
* @param configFile the config file must match the meta attribute "config-file" in the hibernate mapping file
* @return the active Session
*/
protected Session getSession(String configFile) {
if (null != session && session.isOpen()) return session;
else if (null != sessionFactory) {
Session s = currentSession.get();
if (null == s || !s.isOpen()) {
s = sessionFactory.openSession();
currentSession.set(s);
}
return s;
}
else {
Session s = currentSession.get();
if (null == s || !s.isOpen()) {
s = getSessionFactory(configFile).openSession();
currentSession.set(s);
}
return s;
}
}
更新 ：
這是 Oracle 數據庫中的當前設置
RESOURCE_NAME, CURRENT_UTILIZATION, MAX_UTILIZATION
sessions 93 156
enqueue_locks 81 149
enqueue_resources 18 52
我嘗試使用最新版本的 c3p0
c3p0-0.9.5.2.jar 安裝在c3p0-0.9.1.1.jar
我的用例：
我正在運行與 DB（Oracle 12c）的並行連接 - 1 個實例 - 以測試我是否從序列中獲得不同的序列值。 隨着並行連接的增加，有一點我得到"ORA-12519, TNS:no appropriate service handler found"
什么有效：
1.進程limit_value被命中。 我增加了它。
ALTER system SET processes=XXX SCOPE=SPFILE;
逐漸增加 XXX（比如 +200 左右），因為如果你在 1 中把它增加到一個太高的值，你可能無法啟動你的 Oracle 實例，因為它不支持它（閱讀：內存限制，操作系統限制, ...)
spfile中生效。對於靜態和動態參數，更改都記錄在spfile中，並且只會在下次重新啟動時生效。）select resource_name, current_utilization, max_utilization, limit_value
from v$resource_limit
where resource_name = 'processes';
show parameters processes; // will also work
注意：您可能會注意到sessions參數也會發生變化。 這是因為sessions和processes協同工作，Oracle 將根據選擇的processes limit_value 重新計算sessions limit_value。
好吧，讓我們把 Oracle 偵聽器/數據庫配置的事情留到以后，嘗試簡單的事情：
你能檢查一下jdbc url是否正確嗎？ 在這種情況下，請注意 SID 和服務名稱的差異：
對於 SID
<property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:production"/>
對於服務名稱
<property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521/production"/>

為什么我會收到此 Oracle 連接錯誤？ ORA-12519，TNS：找不到合適的服務處理程序Java JDBC - 如何使用服務名稱而不是 SID 連接到 Oracle
您可以嘗試使用“通用連接池”，這是一個用於測試的 Java 連接池。 有關詳細信息，請參閱博客“ UCP with Hibernate ”。
