DB2使用事件监控器抓取返回行数超过固定值的SQL语句

DB2中，有些SQL语句返回的行数可能很多，有些SQL语句的执行时间可能很长， 如何把这些SQL语句抓取出来？

下面的例子示意了如何抓取返回行数超过15行的SQL语句。 测试了3条SQL，其中有两条返回结果超过15行

db2 "connect to SAMPLE"

db2 "CREATE EVENT MONITOR WLM_EVENT FOR ACTIVITIES WRITE TO TABLE ACTIVITY (TABLE WLM_EVENT ),ACTIVITYSTMT (TABLE WLM_EVENT_STMT ),ACTIVITYVALS (TABLE WLM_EVENT_VALS  ),CONTROL (TABLE WLM_EVENT_CONTROL  )"

db2 "CREATE THRESHOLD DBMAXCOST_COLLECT FOR DATABASE ACTIVITIES ENFORCEMENT DATABASE WHEN SQLROWSRETURNED > 15 COLLECT ACTIVITY DATA WITH DETAILS AND VALUES CONTINUE"

db2 "set event monitor WLM_EVENT state=1"

db2 "select * from employee"

db2 "select * from employee where empno < 150"

db2 "select * from employee where empno > 150"

db2 "set event monitor WLM_EVENT state=0"

db2 "select PARTITION_KEY, ACTIVATE_TIMESTAMP,substr(APPL_ID,1,40) as APPL_ID, substr(STMT_TEXT,1,50) as STMT_TEXT from WLM_EVENT_STMT"

PARTITION_KEY ACTIVATE_TIMESTAMP         APPL_ID                                  STMT_TEXT

------------- -------------------------- ---------------------------------------- --------------------------------------------------

            0 2016-04-27-09.55.14.464777 *LOCAL.DB2INST1.160427014639             select * from employee

            0 2016-04-27-09.55.14.464777 *LOCAL.DB2INST1.160427014639             select * from employee where empno > 150

  2 record(s) selected.

db2 "drop  THRESHOLD DBMAXCOST_COLLECT"

db2 "drop event monitor WLM_EVENT"

db2 "drop table WLM_EVENT"

db2 "drop table WLM_EVENT_STMT"

db2 "drop table WLM_EVENT_VALS"

db2 "drop table WLM_EVENT_CONTROL"
