文档解释

ORA-15511: cannot process workload capture because no user sessions were recorded

Cause: No user sessions were recorded in the given workload capture. Processing this capture failed because no user workload was captured.

Action: Capture a workload in which at least one user session connects and performs some operations.

ORA-15511表示未记录到任何用户会话,无法进行工作负载捕获。

官方解释

ORA-15511表示没有记录任何用户会话,不能处理工作负载捕获。

常见案例

通常,如果没有记录到任何用户会话,那么系统将不能处理工作负载捕获,会报出ORA-15511错误。

一般处理方法及步骤

1. 检查当前是否有任何工作负载捕获在进行。

2. 使用如下命令查看当前工作负载捕获事件是否正在运行:

SQL> SELECT t.username, t.terminal, t.program FROM v$sqltext_with_newlines t WHERE t.sql_id IN(SELECT s.sql_id FROM dba_hist_active_sess_history s WHERE event = ‘capture workload’);

3. 如果已有工作负载捕获正在运行,那么应该等到它完成后再运行新的工作负载捕获任务。

4. 如果没有运行的工作负载捕获任务,应该使用如下命令检查是否已有工作负载捕获正在处理:

SQL> SELECT * FROM dba_hist_workload_capture;

5. 如果已有工作负载捕获正在处理,则应该等待它完成后再运行新的工作负载捕获任务。

6. 如果当前没有工作负载捕获任务在运行,则应尝试重新启动一次数据库。
