如何创建监视SQL语句的事件监控器

Posted 2023-04-05

参考技术A 打2008事件探查器工具栏按钮新建跟踪连要跟踪数据库实例确定即新建跟踪查看链接数据库实例语句执行创建完跟踪
每客户端都ClientProcessID想跟踪客户端语句执行情况：
先让客户端查询报表通事件探查器看看ClientProcessID暂停事件探查
文件——属性——筛选——面找ClientProcessID,等于处双击填入客户端ClientProcessID,确定重新启追看客户端运行情况！

sql 创建用于锁定的事件监视器

CREATE EVENT MONITOR mylockevmon
        FOR LOCKING WRITE TO TABLE LOCK (TABLE mylockevmon.LOCK), LOCK_PARTICIPANTS (TABLE mylockevmon.LOCK_PARTICIPANTS), LOCK_PARTICIPANT_ACTIVITIES (TABLE mylockevmon.LOCK_PARTICIPANT_ACTIVITIES), LOCK_ACTIVITY_VALUES (TABLE mylockevmon.LOCK_ACTIVITY_VALUES), CONTROL (TABLE mylockevmon.CONTROL);

SET EVENT MONITOR mylockevmon STATE 1;

SELECT
	ACT.MEMBER
	,ACT.EVENT_TIMESTAMP
	,substr(rtrim(PART.table_schema)||'.'||PART.table_name,1,40) as tabela
	,PART.APPL_ID,PART.AUTH_ID
	,CASE
	WHEN LENGTH(ACT.STMT_TEXT) > 807 THEN
		X'0A' || SUBSTR(rtrim(REPLACE(ACT.STMT_TEXT,X'0A',' ')),1,350) || ' (...) ' || SUBSTR(RIGHT(REPLACE(ACT.STMT_TEXT,X'0A',' '),450),1,450)
	ELSE
		X'0A' || SUBSTR(rtrim(REPLACE(ACT.STMT_TEXT,X'0A',' ')),1,807)
	END AS STMT_TEXT

	FROM 
		ADILSON.LOCK_PARTICIPANTS PART, ADILSON.LOCK_PARTICIPANT_ACTIVITIES ACT
			WHERE ACT.EVENT_ID = PART.EVENT_ID AND
				ACT.PARTICIPANT_NO = PART.PARTICIPANT_NO
			AND ACT.EVENT_TYPE = 'DEADLOCK'
		ORDER BY ACT.EVENT_TIMESTAMP DESC
