Sql statements in v$sqlarea

Hi
When I get the sqls from v$sqlarea, does these sqls already executed, or currently runnıng?

I suggest you check the Oracle Document,
While showing similar content, you might also note there are difference between V$SQLAREA and V$SQL view
V$SQL
V$SQL lists statistics on shared SQL area without the GROUP BY clause and contains one row for each child of the original SQL text entered. Statistics displayed in V$SQL are normally updated at the end of query execution. However, for long running queries, they are updated every 5 seconds. This makes it easy to see the impact of long running SQL statements while they are still in progress.
V$SQLAREA
V$SQLAREA lists statistics on shared SQL area and contains one row per SQL string. It provides statistics on SQL statements that are in memory, parsed, and ready for execution.

Missingf SQL Statements in v$sqlarea

Hi,
i´m tracing some sql statements and from time to time they disapear very quickly from the shared pool.
i´m looking into v$sqlarea and the funny thing is, i thought "all" historical statments will be copied to dba_hist_sqltext. But thery are missing there too.
Some statments are away after a couple of minutes, but the shared pool is quit large enough.
I had the same problem inside the em (10g) many (historical) statements can´t be seen after a couple of minutes.
Are some other views for that ?
Thanks
Marco

How to find sql statement with Unix process pid

Hi
how to find sql statement with Unix process pid
is there any view to find that.
please if so let me know
Thanks in advance

this is how I am doing this:
oracle 7352340 7459066 0 07:47:10 - 0:00 oracleJDERED (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
oracle 7459066 5386396 2 07:47:10 pts/1 0:01 sqlplus
select sid,serial# from v$session where process='7459066';
SID SERIAL#
2178 6067
select sql_text
from
v$sqlarea a,
v$session b
where a.hash_value = b.sql_hash_value
and b.sid = 2178
;

Trying to find a specific SQL statement to determine its cost

If an sql statement is executed will it ALWAYS show up in the awrrpt report? (10g)
I am a developer DBA and was handed an SQL statement by the production DBA as being a problem during a specific timeframe within the past hour.
That statement does not show up in v$LongOps (although other older ones are) nor does it appear in v$sqltext and is not in the awrrpt even when I run the report for the entire day.
Any other ideas or can I safely broach the Production DBA without looking like an idiot?!!
Thanks

I am not using awrrpt report but for sure if your statement has been executed it must have been in v$sqltext but maybe it did not stay very long because it has been rarely executed and replaced in the shared pool by other SQL statements that have been more executed.
You could setup a copy of your production database on a similar host and run the statement several time in single user mode to check at least its performance in single user with sql_trace=TRUE and tkprof.
If your statement is SELECT your could also execute it in your production database and check at the sametime v$sqltext and also v$sqlarea, especially for:
DISK_READS      NUMBER      Sum of the number of disk reads over all child cursors
BUFFER_GETS      NUMBER      Sum of buffer gets over all child cursors
USER_IO_WAIT_TIME      NUMBER      User I/O Wait Time (in microseconds)
CPU_TIME      NUMBER      CPU time (in microseconds) used by this cursor for parsing, executing, and fetching
ELAPSED_TIME      NUMBER      Elapsed time (in microseconds) used by this cursor for parsing, executing, and fetching

Bind Variables in SQL Statement

can someone tell me if there is a way to find out what the bind variables values are in an sql statement extracted from any of the v$sql or v$sqlarea type tables ?
sql example:
update DTree set OriginOwnerID=:A
where OriginOwnerID=:B and OriginDataID=:C
Thanks
Jim

Hi damorgan
i see two ot of the three:
SQL> desc gv$sql_bind_capture
ERROR:
ORA-04043: object gv$sql_bind_capture does not exist
i just trying to see what bind variable values would be associated with the sql when i extract the sql from v$sql and if that is even possible
Thanks

Using bind variables with sql statements

We connect from a VB 6.0 program via OO4O to an Oracle 8.1.7 database, using bind variables in connection with select statements. Running ok, but performance again by using bind vars not as good as expected!
When looking into the table v$sqlarea, we were able to detect the reason. We expected that our program submits the sql statement with bind vars, Oracle parses this once, and with each select statement again, we do not have a reparse. But: It seems that with each new session Oracle reparses the sql statement, that is, Oracle is not able to memorize or cache bind vars and statements. Even more worrying, this kind of behaviour was visible with each new dynaset, but the same database/session.
Is there anybody our there with an idea of what is happening here?
Code snippet:
Dim OraSession As OracleInProcServer.OraSessionClass
Dim OraDatabase As OracleInProcServer.OraDatabase
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
Set OraDatabase = OraSession.OpenDatabase(my database", "my connect", 0&)
OraDatabase.Parameters.Add "my_bind", 0, ORAPARM_INPUT
OraDatabase.Parameters("my_bind").DynasetOption = ORADYN_NOCACHE
OraDatabase.Parameters("my_bind").serverType = ORATYPE_NUMBER ' Bind Var Type
Dim RS As OracleInProcServer.OraDynaset
strSQLstatement= "Select * from my_table where igz= [my_bind] "
Set RS = OraDatabase.CreateDynaset(strSQLstatement, &H4)
OraDatabase.Parameters("my_bind").Value = myValue
RS.Refresh
Cheers and thanks a lot :)

Select the progress of an another sql statement

What I want to do is to monitor the progress of a sql statement which takes a long time. How many percent of the statement is already done.
I know there is the possibility to do this with a query.
But I can' t remember how to do this exactly.
Can somebody help me?
Thanks a lot!

     FROM V$SESSION_LONGOPS L
          ,V$SESSION S
          -- , V$SQLAREA A
     WHERE L.TIME_REMAINING <> 0
          AND L.SID = S.SID
          AND L.SERIAL# = S.SERIAL#
;Note that V$SESSION_LONGOPS as a rule does not show long operations which take a lot of index range scans - this is not a "long operation"

Which view contains the exact sql statement

Dear All,
Developers have used bind variables in their sql inside their applications (for example: SELECT Name FROM Employee WHERE EmployeeID =:empno)
This bind variable is supplied a value within the application. I wanted to know which data dictionary view will give me the exact sql statement which gets executed.
For example SELECT Name FROM Employee WHERE EmployeeID = 100;
When I query V$SQL, V$SQLAREA, V$SQLTEXT, I get the same query with the bind variables (SELECT Name FROM Employee WHERE EmployeeID =:empno), instead can i get the query which actually holds the value for the bind variable.
Regards,
qA

Add sql statements in SGA

select a.address address,
s.hash_value hash_value,
s.piece piece,
s.sql_text sql_text,
u.username parsing_user_id,
c.username parsing_schema_id
from v$sqlarea a,
v$sqltext_with_newlines s,
dba_users u,
dba_users c
where a.address=s.address
and a.hash_value=s.hash_value
and a.parsing_user_id=u.user_id
and a.parsing_schema_id=c.user_id
and exists (select 'x'
from v$sqltext_with_newlines x
where x.address=a.address
and x.hash_value=a.hash_value
and upper(x.sql_text) like '%UNION%')
order by 1,2,3
On executing the above statement the server display list of sqltext present in sga. We know that the server first search for the record in sga and if it is not
present in SGA it searches in data files.
My question is ,adding all the sql statements in sga manually is advisable? will that improve the performance?

Vinodh2 wrote:
In production the users uses some sql statement frequently. So those statements should be in the sga for better performance. The dbms package said by you takes object as input. What is object here?
Did you check the last line I pasted from document?
The value for this identifier is the concatenation of the address and hash_value columns from the v$sqlarea view.Each SQL in SQL AREA has a hash_value to identify it. You can use this hash value to decide which SQL want to keep in shared pool.
Having Dynamic sql statements(records fetched based on varying filter condtion) called from interfaces will not help.
But having static sql statements helps.
In that case how to include those sql.Like said, you are introducing some more problems instead of any real gain by trying to micro manage how shared pool work. You should let Oracle take care it with it's own algorithm. Unless some rare cases, that you have limited shared pool and super busy system you want to pin some SQL in the shared pool with provide package.

For Finding sql statements which consumes High CPU

Hai,
Can any help me for finding, which sql statements are comsumes high CPU

generaly:
1. from unix site :
us top command or ps (but this depend on platform) -> use pid in select * from v$process where spid <>
2. from db site
select * from v$sql_area order by buffer_gets desc ;
this can You join with v$session where v$session.sql_address=v$sqlarea.address
and when You wont to see % of os select *spid from v$process where addr=<v$session.paddr>
and then in unix ps -ef | grep <spid>
But point 2 is maybe discutable because also parse is one style how to consume CPU ... etc
In 10g
from AWR dba_hist_osstat -> DBA_HIST_SQLSTAT You can see high usage CPU interval , but this show You not momentaly action , but historical data
momentali from ASH
now I study viraq_sh script ... I thing this answer your question tottally

Current running sql statement in procedure?

How to identify the current running sql statement in procedure or package? From the v$sqlarea, i can see the only procedure name with parameters, but not current execution statement? is there any dba view to know the current execution statement in 9i & 10g ?

hi
u can also use dba_source view to know which sql statement issued by which user

It's up to 70-80 session executing one same sql. Is there any idea or suggest for this my case.
So thanks
Ch

You could look at the SQL (from V$SQLSTATS, V$SQL or V$SQLAREA) and then determine what it is doing and then get some clues as to why one database has multiple executions of the SQL . Most developer leads would be able to say "ah ... this SQL is executed by this module in this part of the application when the user chooses this option". Then you figure out why you have multiple users choosing the option.
OR there could be dependencies between different statements or enqueue waits -- and multiple sessions waiting on the same lock !

How do i see the sql statements that are run ?

i want to see (in a log file) what are the sql statements that oracle had ran.
how do i do it ? what configurations should i do ? how ?
please help ... thanks

Current SQL statements are viewed in dynamic tables:
SELECT SCHEMANAME, SQL_ADDRESS, SQL_TEXT, last_call_et
FROM V$SESSION, V$SQLAREA
WHERE V$SESSION.SQL_ADDRESS=V$SQLAREA.ADDRESS
A historical log of all SQL statements is recorded in Oracle Archived Logs, and can be viewed using the Oracle Logminer approach. This process requires your database to be in ARCHIVELOG mode, and that Logminer be configured to read the archived logs.

How could I extract past executed SQL statement from dictionary ?

We use oracle11gR2 on win2008R2.
How could I extract the past executed SQL statement from dictionary ? (Is it possible from V$SQLTEXT or other dictionary table ?)

Hi,
You can find executed SQL in V$SQLAREA view (if it's still in memory). If it does'n't exist and you have AWR enabled you can query DBA_HIST_SQLTEXT table, but remember that the statistic information in AWR tables is filtered (1 out of 10).
I.Arsov
As you know when taking snapshot oracle will capture only top sql statements and stored in AWR.
But can you please link(source) dba_hist_sqltext contain only 1 out of 10 filtered data?. In dba_hist_active_sess_history yes it contain 1 out of 10 sampled data.

Current Exact sql statement

Dear Group
Can any one suggest how can i see the Exact sql which was fired from the application.
SELECT SQL_TEXT
FROM V$SQLAREA
WHERE (ADDRESS, HASH_VALUE) IN
(SELECT SQL_ADDRESS, SQL_HASH_VALUE
FROM V$SESSION
WHERE SID = &sid_number)
I mean with out "SYS_B_0" in the sql statement
Thank you

Hi,
The value you are looking for is called as bind value.
If you are on 8i, I am not sute how you will find the value. You can certainly it in the trace file.
In 9i onwards, there is a view, v$sql_bind_data, which shows the bind value. But, still it is tricky.
