reliable message
reliable message 可能是由 10.2.0.4 上的RAC 相关Bug 6148054 引起
In some cases, the SQL trace will show a lot of 'reliable message' waits. That just means that the local node (the one that started the snapshot) is waiting for the remote nodes to complete. The real issue at that point will be in the trace files from the remote nodes.
SQL*Net more data from client 平均等待达到36ms , 建议你检查网络状况。
从DB 侧 观察性能负载 几乎没有, 建议你在客户机上 安装oracle client 并测试登录。 |
