DB2日常管理

执行时间最长的10条SQL语句（按时间降序排列），可保存为脚本方便调用：
db2 "SELECT rows_read / (num_executions + 1) as avg_rows_read,rows_written / (num_executions + 1) as avg_rows_written,stmt_sorts / (num_executions + 1) as avg_sorts,total_exec_time / (num_executions + 1) as avg_exec_time,substr(stmt_text,1,1000) as SQL_Stmt FROM SYSIBMADM.SNAPDYN_SQL ORDER BY avg_exec_time desc fetch first 10 rows only"

db2 "select agent_id,appl_status,elapsed_time_min from sysibmadm.long_running_sql order by elapsed_time_min desc fetch first 5 rows only"

db2 "select AGENT_ID,appl_name,stmt_text from sysibmadm.long_running_sql" |grep -i delete from TB_TMG_DEMO
