I have the sql id of a query. Now I want to get the machine name and IP of the machine from which this query was run.
I have already checked the sql id in V$SESSION and V$ACTIVE_SESSION_HISTORY but didn't get any results.
I am able to find the sql id in v$sql and LAST_LOAD_TIME is today(7 July 2016).
select LAST_LOAD_TIME from v$sql where SQL_ID='0jf4618m2u7aw' order by LAST_LOAD_TIME desc;
2016-07-04/17:26:02
2016-07-04/17:26:02
select * from V$SESSION where SQL_ID='0jf4618m2u7aw';
no rows selected
select * from V$ACTIVE_SESSION_HISTORY where SQL_ID='0jf4618m2u7aw';
no rows selected
Please help. Thanks in advance.
You have a couple of options...
If it is an active session/process, you can use v$session and v$process:
SELECT DISTINCT
MACHINE,
UTL_INADDR.GET_HOST_ADDRESS(MACHINE) AS IP_ADDR
FROM V$SESSION S,
V$PROCESS P
WHERE S.PADDR = P.ADDR
AND S.SQL_ID = '0jf4618m2u7aw';
If you want a historical view, the DBA_HIST_ACTIVE_SESS_HISTORY might be your friend:
SELECT DISTINCT
MACHINE,
UTL_INADDR.GET_HOST_ADDRESS(MACHINE) AS IP_ADDR
FROM DBA_HIST_ACTIVE_SESS_HISTORY DHASH
WHERE DHASH.SQL_ID = '0jf4618m2u7aw'
AND DHASH.SQL_EXEC_START > TRUNC(SYSDATE);

I want to fetch sql query with machine name where sql query has been run and machine name can belong's to any user. Please guide how is it possible to get that by joing tables like DBA_hist_sql or any other table.
I can suggest such variant
select
s.sql_id,
s.sql_text,
d.machine
from
v$sql s,
dba_hist_active_sess_history d
where
d.sql_id = s.sql_id
Maybe there is better variant or more related to your question. I hope it wil be helpful for you.
I let you links on documentation of these views.
DBA_HIST_ACTIVE_SESS_HISTORY
V$SQL
You can join DBA_HIST_ACTIVE_SESS_HISTORY and DBA_HIST_SQLTEXT , as long as the sql has been captured in the workload repository.
In the DBA_HIST_ACTIVE_SESS_HISTORY you have the field MACHINE, where you got the value of SYS_CONTEXT('userenv','host') .
You can join both views by sql_id.
However, the query will not be registered on the workload repository if it's not meaningful. You can modify this behaviour by changing settings of AWR using DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS
An example
select
distinct s.sql_id,
s.sql_text,
d.machine ,
u.username ,
d.program
from
gv$sql s inner join dba_hist_active_sess_history d
on ( d.sql_id = s.sql_id and S.INST_ID = D.INSTANCE_NUMBER )
inner join dba_users u on ( D.USER_ID = U.USER_ID )
where
u.username = '&1'
S.SQL_ID = '&2'
order by D.SAMPLE_TIME desc
You can apply the filter by username or sql_id, or both. keep in mind that the field USERNAME will show you the Oracle user who executed the query, not the operating system user behind that connection.
I want to find out the query for which any operation is blocked.
From DBA I'm getting input that particular session is blocked but I cannot proceed with investigation further without knowing which query is causing issue.
is there any way to find out exact query causing issue?
Oracle Blocking session is very common. Please check the below query it will help you to get the detailed information.
select l1.inst_id,l1.sid, ' IS BLOCKING ', l2.sid,l1.type,l2.type,l1.lmode,l2.lmode,l2.inst_id
from gv$lock l1, gv$lock l2
where l1.block =1 and l2.request > 0and l1.id1=l2.id1
and l1.id2=l2.id2;
You can use the following query to find out whichs sessions are bloking and what they do:
select s.module,
s.program,
s.machine,
s.osuser,
sql.sql_text
from v$session s,
v$sqlarea sql
where s.sql_id = sql.sql_id
and s.sid in (select blocking_session from v$session)
First get the SQL_ID of the BLOCKING session from this script:
SELECT /*+ RULE */
s.sid,
s.serial#,
p.spid "OS SID",
s.sql_hash_value "HASH VALUE",
s.username "ORA USER",
s.status,
s.osuser "OS USER",
s.machine,
s.terminal,
s.type,
s.program,
s.logon_time,
s.last_call_et,
s.sql_id,
l.id1,
l.id2,
decode(l.block,0,'WAITING',1,'BLOCKING') block,
decode(
l.LMODE,1,'No Lock',
2,'Row Share',
3,'Row Exclusive',
4,'Share',
5,'Share Row Exclusive',
6,'Exclusive',null) lmode,
decode(
l.REQUEST,1,'No Lock',
2,'Row Share',
3,'Row Exclusive',
4,'Share',
5,'Share Row Exclusive',
6,'Exclusive',null) request ,
round(l.ctime/60,2) "MIN WAITING",
l.type
FROM v$process p, v$session s, v$Lock l
where p.addr = s.paddr
and s.sid=l.sid
and
(l.id1,l.id2,l.type) in
(SELECT l2.id1, l2.id2, l2.type
FROM V$LOCK l2
WHERE l2.request<>0)
order by l.id1,l.id2,l.block desc;
Then pass this SQL_ID into this script:
select sql_text from v$sqltext
where sql_id=<SQL_ID>;
Hi I am learning ASH and AWR tables but any ideas as to how i can get list of sql, objects and schema owner accessed by a give user in last 30 days ? Basically get all SQL text, and then search within this SQL to see if a given object (table, package, function, view etc ) is accessed for a given schema and by which user ? Any ideas suggestion on where and how to start ?
You could join the following views -
DBA_HIST_ACTIVE_SESS_HISTORY
DBA_USERS
DBA_HIST_SQLTEXT
To filter the history for last 30 days, use sample_time of DBA_HIST_ACTIVE_SESS_HISTORY view.
Something like -
SELECT
h.sample_time,
u.username,
h.program,
h.module,
s.sql_text
FROM
DBA_HIST_ACTIVE_SESS_HISTORY h,
DBA_USERS u,
DBA_HIST_SQLTEXT s
WHERE sample_time >= SYSDATE - 30
AND h.user_id=u.user_id
AND h.sql_id = s.sql_iD
ORDER BY h.sample_time
/
The very best and simplest way to fetch related data using below query.
SELECT H.SAMPLE_TIME,
U.USERNAME,
H.PROGRAM,
H.MODULE,
S.SQL_TEXT,
H.SQL_ID,
H.TOP_LEVEL_SQL_ID,
H.BLOCKING_SESSION_STATUS
FROM DBA_HIST_ACTIVE_SESS_HISTORY H, DBA_USERS U, DBA_HIST_SQLTEXT S
WHERE H.SAMPLE_TIME >= SYSDATE - 30
AND H.SQL_ID = S.SQL_ID
--AND H.PROGRAM IN ('Toad.exe', 'SQL Developer')
--AND U.USERNAME ='YOUR_USERNAME'
ORDER BY H.SAMPLE_TIME DESC
In the above code you can also fetch data based on your requirements as below.
1. Custom user data: Just modify YOUR_USERNAME with your real username.
2. Program: Program name can be anything like SQL Developer or JDBC Thin client to identify from which client the queries are getting triggered, but optional.
Hope it will help and answer to your question. Thanks :)
Good afternoon. How do I get Oracle, see what procedures are running?
Depending on your needs, this might suffice (but relies on access to v$session and dba_objects):
select 'CALLED PLSQL', vs.username, d_o.object_name -- whatever info you need
from dba_objects d_o
inner join
v$session vs
on d_o.object_id = vs.plsql_entry_object_id
union all
select 'CURRENT PLSQL', vs.username, d_o.object_name
from dba_objects d_o
inner join
v$session vs
on d_o.object_id = vs.plsql_object_id
As per the docs:
PLSQL_ENTRY_OBJECT_ID - ID of the top-most PL/SQL subprogram on the stack; NULL if there is no PL/SQL subprogram on the stack
PLSQL_OBJECT_ID - Object ID of the currently executing PL/SQL subprogram; NULL if executing SQL
select 'CALLED PLSQL', vs.username, d_o.object_name -- whatever info you need
from dba_objects d_o
inner join
v$session vs
on d_o.object_id = vs.plsql_entry_object_id
union all
select 'CURRENT PLSQL', vs.username, d_o.object_name
from dba_objects d_o
inner join
v$session vs
on d_o.object_id = vs.plsql_object_id
If I run the SQL in Fig. 1 below, it may return something like this:
Select fname, lname from name_tbl where nam_key = :key
Without using some fancy DBA trace utility, how can I query an Oracle system table to find the value of the bind variable “:key”?
Figure 1. - List the current running sql statement.
select sid, username, sql_text
from v$session,
v$sqltext
where sql_address = address
and sql_hash_value = hash_value
order by sid, piece;
select name, value_string
from v$sql_bind_capture
where sql_id = your_query_id
Upd. or, of course:
select sql_id, value_string
from v$sql_bind_capture
where name = ':key'
