我们常常有需要从SHELL里面传入参数，到Sqlplus里面执行命令。
比如我跑一个Top进程，看到某个进程非常消耗资源。
Code:
oracle@main-db1$top
last pid:
4327;

我想很快看到这个进程是什么，手工进入SQLPLUS，根据v$session, v$process一个一个join，非常麻烦。
最好能够从shell 里面直接输入spid,马上让我看到这个进程是什么，在干什么。
下面是我写的一个简单例子，
Code: [Copy to clipboard]
sqlplus /nolog <<EOF
connect / as sysdba
col machine format a30
col program format a40
set line 200
select sid,serial# ,username,osuser,machine,program,process,to_char(logon_time,'yyyy/mm/dd hh24:mi:ss')
from v\$session where paddr in
( select addr from v\$process where spid in($1));
select sql_text from v\$sqltext_with_newlines
where hash_value in
(select SQL_HASH_VALUE from v\$session where
paddr in (select addr from v\$process where spid=$1)
)
order by piece;
exit;
EOF
有了这个简单例子之后，我可以很方便，及时的看到这个进程在干什么：
Code: [Copy to clipboard]
oracle@main-db1$./whoisit.sh 26240
