[原创]DB2 监控表的使用

DB2

摘要

DB2 v10之后增加了很多MON_GET_TABLE等监控函数的使用,总共有上百个监控函数,对于这些函数如果不常使用,除了查看informaction center之后,很难全部记住并加以使用。本文汇总了通过sql来汇总有哪些监控函数和每个函数能返回的结果集有哪些,不必全部记住这些函数或者查看information center即可使用


有哪些monitoring functions?

通过下面的sql语句即可查看

db2 "select
  substr(rout.ROUTINENAME,1,48) as ROUTINENAME,
  substr(rout.SPECIFICNAME,1,48) as SPECIFICNAME
from sysibm.sysroutines rout
where 
  rout.function_type='T'
  and substr(rout.ROUTINENAME,1,4) in ('SNAP','MON_','ENV_','COMP')
  and substrb(rout.SPECIFICNAME,-3,3) not in ('V91', 'V95', 'V97', '_AP')
order by rout.ROUTINESCHEMA,rout.ROUTINENAME,rout.SPECIFICNAME";

DB2 v10.1fp5结果如下(117行):

查看某个monitoring functions的结果集?

如果我想查看某个monitoring functions的返回结果集合有哪些?如何查看呢?

只要把ROUTINENAME更改为你上面想要的某个监控函数名。

db2 "select
  substr(P.ROUTINENAME,1,48) as ROUTINENAME,
  substr(P.SPECIFICNAME,1,48) as SPECIFICNAME,
  case when P.ROWTYPE in ('B','O','P') then CHAR('IN',3) else CHAR('OUT',3) end as IN_OUT,
  cast(p.ORDINAL as char(3)) as ORD,
  substr(P.PARMNAME,1,40) as PARMNAME,
  substr(P.TYPENAME,1,16) as TYPE
from sysibm.sysroutines r,  sysibm.sysroutineparms p
where p.routineschema=r.routineschema
  and p.routinename=r.routinename
  and p.specificname=r.specificname
  and r.function_type='T'
  and r.ROUTINENAME='SNAP_GET_UTIL'
order by P.ROUTINESCHEMA,P.ROUTINENAME,P.SPECIFICNAME,IN_OUT,P.ORDINAL";

例如:

db2inst1:/dbhome/db2inst1$ db2 "select
>   substr(P.ROUTINENAME,1,48) as ROUTINENAME,
>   substr(P.SPECIFICNAME,1,48) as SPECIFICNAME,

>   substr(P.TYPENAME,1,16) as TYPE

或:

db2 "select
  substr(P.ROUTINENAME,1,48) as ROUTINENAME,
  substr(P.SPECIFICNAME,1,48) as SPECIFICNAME,
  case when P.ROWTYPE in ('B','O','P') then CHAR('IN',3) else CHAR('OUT',3) end as IN_OUT,

查看某个MON_GET的参数列表?

如何查看某个MON_GET的参数列表呢?我们知道查用类似的如table(MON_GET_TABLE(‘’,’’,-2))来使用MON_GET函数或者table(MON_GET_TABLESPACE(‘’,-2))。

但如何查看必须的参数呢?

可以参考如下SQL问来确认(MON_GET_TABLE可以替换成你想要的函数名):

db2 "select
  substr(P.ROUTINENAME,1,48) as ROUTINENAME,
  substr(P.SPECIFICNAME,1,48) as SPECIFICNAME,
  'IN' as IN_OUT,
  cast(p.ORDINAL as char(3)) as ORD,
  substr(P.PARMNAME,1,40) as PARMNAME,
  substr(P.TYPENAME,1,16) as TYPE
from sysibm.sysroutines r,  sysibm.sysroutineparms p
where p.routineschema=r.routineschema
  and p.routinename=r.routinename
  and p.specificname=r.specificname
  and r.function_type='T'
  and r.ROUTINENAME='MON_GET_TABLE'
  and P.ROWTYPE in ('B','O','P')
order by P.ROUTINESCHEMA,P.ROUTINENAME,P.SPECIFICNAME,IN_OUT,P.ORDINAL";

如下例(MON_GET_LOCKS):

db2inst1:/dbhome/db2inst1$         db2 "select

>           'IN' as IN_OUT,                             
>           cast(p.ORDINAL as char(3)) as ORD,

应用

查看sales表的情况,可用下面sql语句

db2 "select * from table(mon_get_table('DB2INST1','SALES', -2)) as mgt with ur"

或者:

db2 "select * from table(mon_get_table('','', -2)) as mgt where tabschema='DB2INST1' and tabname='SALES' with ur"
