library cache pin等待事件的处理

在后台sys用户下执行：

select s.sid || ',' || s.serial# sid_serial,

kglpnmod "mode held",

kglpnreq "request"

from sys.x$kglpn p, v$session s

where p.kglpnuse = s.saddr

and kglpnhdl = (select p1raw

from v$session_wait

where sid = &SID_IN_LIBRARY_CACHE_PIN);

或者：

select sid Holder ,KGLPNUSE Sesion , KGLPNMOD Held, KGLPNREQ Req

from x$kglpn , v$session

where KGLPNHDL in (select p1raw from v$session_wait

where wait_time=0 and event like 'library%')

and KGLPNMOD <> 0

and v$session.saddr=x$kglpn.kglpnuse ;

或者：

select sql_text from v$sqlarea

where (v$sqlarea.address,v$sqlarea.hash_value)

in (select sql_address,sql_hash_value from v$session where sid in (

select sid

from x$kglpn , v$session

where KGLPNHDL in (select p1raw from v$session_wait

where wait_time=0 and event like 'library%')

and KGLPNMOD <> 0

and v$session.saddr=x$kglpn.kglpnuse );

查到held>0
的sid，如果local=no
，请沟通是否可以kill掉这个进程
