Hibernate错误:无法在活动的全局事务中打开自动提交

Question

我在部署应用程序时遇到错误.

环境是:

• Jboss 7.1.3 + Hibernate 4 + JPA
• OJDBC:ojdbc6.jar

堆栈跟踪如下,

standalone.xml中的数据源配置是,

<xa-datasource jta="true" jndi-name="java:jboss/datasources/PsaDS" pool-name="PsaDS" enabled="true" use-java-context="true" use-ccm="true">
  <xa-datasource-property name="URL">
        jdbc:oracle:thin:@<hsot>
  </xa-datasource-property>
  <driver>oracle</driver>
  <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
  <xa-pool>
        <min-pool-size>2</min-pool-size>
        <max-pool-size>50</max-pool-size>
        <prefill>true</prefill>
  </xa-pool>
  <security>
        <user-name>user</user-name>
        <password>pwd</password>
  </security>

我们使用的驱动程序是,

<drivers>
  <driver name="oracle" module="com.oracle.ojdbc6">
        <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
  </driver></drivers>

Answer 1

尝试对定义标签中的standalone.xml进行以下更改<xa-datasource>：

在标签内添加以下内容<xa-pool>：

<is-same-rm-override>false</is-same-rm-override>
<no-tx-separate-pools>true</no-tx-separate-pools>

根据文档：

no-tx-separate-pools：此元素的存在表明需要两个连接池来隔离使用 JTA 事务的连接和不使用 JTA 事务的连接。池是在第一次使用时延迟构建的。它的用例适用于不喜欢使用带或不带 JTA 事务的 XA 连接的 Oracle（可能还有其他供应商）XA 实现。

如果这不能使它单独工作，请尝试在您的<xa-datasource>定义中添加以下内容：

<validation>
      <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"/>
      <stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"/>
      <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"/>
</validation>
