从 JBoss EAP 6.1 升级到 JBoss Wildfly 9 后，我遇到了多个 XA-Datasources 和相关 PersistenceUnits 的问题。我正在使用具有不同用户/模式的 Oracle 数据库。我配置了 2 个 XA 数据源，它们使用相同的连接 URL，但具有不同的用户名。
数据源 1
<xa-datasource jndi-name="java:/DS1" pool-name="DS1">
<xa-datasource-property name="URL">...@<host>:<port>:<ssid></xa-datasource-property>
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
<driver>ojdbc6.jar</driver>
<xa-pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>100</max-pool-size>
</xa-pool>
<security>
<user-name>user1</user-name>
<password>password1</password>
</security>
</xa-datasource>
数据源 2
<xa-datasource jndi-name="java:/DS2" pool-name="DS2">
<xa-datasource-property name="URL">...@<host>:<port>:<ssid></xa-datasource-property>
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
<driver>ojdbc6.jar</driver>
<xa-pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>100</max-pool-size>
</xa-pool>
<security>
<user-name>user2</user-name>
<password>password2</password>
</security>
</xa-datasource>
在 EJB 中，我使用定义的数据源配置了 2 个 EntityManger：
@PersistenceContext(unitName = "DS1")
private EntityManager manager1;
@PersistenceContext(unitName = "DS2")
private EntityManager manager2;
现在在我的 EJB 中调用 manager2.find(...) 时会发生错误。调试代码没有任何反应，几分钟后 TransactionReaper 显示在服务器日志文件中。我认为这是由于超时而发生的。
更改一个日期源 URL 时，例如用<host>IP 或第二个主机别名替换该部分，一切正常，没有任何问题。仅当两个数据源的 URL 相同时才会出现此问题。所以我怀疑是否存在一般配置问题。
有谁知道为什么会出现这个问题？如果您需要更多信息或配置，请告诉我。
