红帽全球峰会6.7.6. Oracle XA 数据源示例
注意
在 Oracle 数据源 10.2 之前的版本里，<no-tx-separate-pools/> 参数是必需的，因为非事务性和事务性连接的混合可能导致错误。对于某些应用程序来说，这个参数已不再是必需的了。
重要
下面的设置必须应用于访问 Oracle XA 数据源的用户以使 XA 恢复可以正常操作。
user 的值是连接 JBoss 到 Oracle 的用户：
- GRANT SELECT ON sys.dba_pending_transactions TO user;
- GRANT SELECT ON sys.pending_trans$ TO user;
- GRANT SELECT ON sys.dba_2pc_pending TO user;
- GRANT EXECUTE ON sys.dbms_xa TO user; (If using Oracle 10g R2 (patched) or Oracle 11g)ORGRANT EXECUTE ON sys.dbms_system TO user; (If using an unpatched Oracle version prior to 11g)
例 6.12.
下面的例子是一个 Oracle XA 数据源配置。这个数据源已被启用，用户已经添加并已设置了检验选项。
<datasources>
<xa-datasource jndi-name="java:/XAOracleDS" pool-name="XAOracleDS">
<driver>oracle</driver>
<xa-datasource-property name="URL">jdbc:oracle:oci8:@tc</xa-datasource-property>
