ASH_REPORT 过程用于以文本形式显示 ASH 报告。
功能适用性
该内容仅适用于 OceanBase 数据库企业版。OceanBase 数据库社区版仅提供 MySQL 模式。
语法
PROCEDURE ASH_REPORT(BTIME IN DATE,
ETIME IN DATE,
SQL_ID IN VARCHAR2 DEFAULT NULL,
TRACE_ID IN VARCHAR2 DEFAULT NULL,
WAIT_CLASS IN VARCHAR2 DEFAULT NULL,
REPORT_TYPE IN VARCHAR2 DEFAULT 'text',
SVR_IP IN VARCHAR2 DEFAULT NULL,
SVR_PORT IN NUMBER DEFAULT NULL,
TENANT_ID IN NUMBER DEFAULT NULL
);
参数说明
| 参数 | 说明 |
|---|---|
| BTIME | 采样开始时间。 |
| ETIME | 采样结束时间。 |
| SQL_ID | 待采样 SQL 的 SQL_ID，不填或填 NULL 则表示不限制 SQL_ID。 |
| TRACE_ID | 待采样 SQL 的 TRACE_ID，不填或填 NULL 则表示不限制 TRACE_ID。 |
| WAIT_CLASS | 待采样的事件类型。WAIT_CLASS 取值参考 GV$ACTIVE_SESSION_HISTORY.WAIT_CLASS 字段的取值，不填或填 NULL 则表示不限制等待类型。 |
| REPORT_TYPE | 报告类型，目前仅支持 TEXT 类型，可不填写。 |
| REPORT_TYPE | 报告类型，目前支持 HTML 和 TEXT 类型，不填则表示默认为 TEXT 类型。 |
| SVR_IP | 用于指定生成 ASH Report 的节点 IP，不填或填 NULL 则表示不限制 IP。 |
| SVR_PORT | 用于指定生成 ASH Report 的节点端口，不填或填 NULL 则表示不限制端口。 |
| TENANT_ID | 用于指定生成 ASH Report 的租户 ID，不填或填 NULL 则表示不限制 TENANT_ID。 |
使用说明
获取 ASH 相关信息需要查询 oceanbase.GV$ACTIVE_SESSION_HISTORY 视图获取。
示例
启用服务器输出。
obclient> SET SERVEROUTPUT ON;
调用 ASH_REPORT，输入需要诊断的开始时间和结束时间。执行后，ASH 报告信息将显示在界面上。
obclient> CALL DBMS_WORKLOAD_REPOSITORY.ASH_REPORT(
TO_DATE('2023-12-18 21:19:00', 'yyyy-MM-dd HH24:mi:ss'),TO_DATE('2023-12-19 13:58:02', 'yyyy-MM-dd HH24:mi:ss') );
示例输出结果如下：
