检查了所有的脚本后，发现没有其他会话、进程造成脚本里面ods表的死锁，后来搜索发现，这是oracle的一个bug4896424，并行dml可能
有个同事说生产机有个perl脚本老是报死锁的错误，脚本里面开启了并行度：错误如下：
failure: ora-12801: error signaled in parallel query server p126, instance nms_ods_ndb1:wgods1 (1)
ora-00060: deadlock detected while waiting for resource (dbd error: ocistmtexecute)
检查了所有的脚本后，发现没有其他会话、进程造成脚本里面ods表的死锁，后来搜索发现，这是oracle的一个bug4896424，并行dml可能会导致ora-00060错误失败。产品（组件）oracle服务器（rdbms）相信受影响版本的范围
