V$sqlarea !!

Hi, the following is my question :
1) I know that oracle can keep track each update to the database table like the update command.
e.g. update tableA
set block = 'Y'
where user_id = 'XXX';
But is there any other table i can select the cached SQL other than v$sqlarea and v$sql.
I am able to select update command from 5 days ago using the v$sqlarea. But if i would like to select the SQL command which i executed more than 5 days ago then what should i do ? Is it any parameter that can be set to configure the no of day to store the old sql text in v$sqlarea.
regards,
Kong

Maybe you can look at auditing?

Possible to find session/user who ran SQL in v$SQLAREA ?

Using this:
select * from v$sqlarea where sql_text like '%2412982%' and sql_text like '%prms%' and module != 'sqlplusw.exe';
I am able to locate a particular instance of a piece of SQL being executed and stored in the library cache.
However, I would really like to know who run it but I never "catch them".
Is there a way?

I think the SQL listed is wrong, as it only display the SQL created by Oracle whenever the user login, which is:
SELECT DECODE('A','A','1','2') FROM DUAL
And all subsequent SQL issued by the user during the session is not listed.
I am also in the midst of trying of get the user issuing the SQL :-).....MANY THANKS AHEAD....

Oracle 8i: full sql text in v$sqlarea

I work with oracle 8i.
is there a v$... that shows the execution plan for a query.
in thev$sqlarea there isn't the full_sqltext column, and I need to know what oracle is doing now.

v$sqltext_with_newlines will produce multiple rows per statement.
You'll need an inline view
select t.hash_value, t.sorts, t.executions, t.buffer_gets, t.disk_reads, tn.sql_text
from v$sqlarea t,
(select hash_value,sql_text
from v$sqltext_with_newlines
order by hash_value, piece) tn
where sn.hash_value = t.hash_value

[Oracle 10.2.0.3] What exactly are "buffer gets" in V$SQLAREA?

I've found this page
[http://www.billmagee.co.uk/oracle/sqltune/080_identify.html]
in which is said:
BUFFER_GETS Cumulative total of memory blocks read for this statement
so if I want to see how many blocks a query read per execution I must do ((disk_reads+buffer_gets)/executions) as suggested from the query on the same page.
select sql_text,
executions,
to_char((((disk_reads+buffer_gets)/executions) * 8192)/1048576,
'9,999,999,990.00') as total_gets_per_exec_mb,
to_char((( disk_reads             /executions) * 8192)/1048576,
'9,999,999,990.00') as disk_reads_per_exec_mb,
to_char((( buffer_gets            /executions) * 8192)/1048576,
'9,999,999,990.00') as buffer_gets_per_exec_mb,
parsing_user_id
from   v$sqlarea
where executions > 0
order by 6 descThis is correct?
Buffer gets refers only to the block found in the buffer cache (not loaded from disk) or to the total amount of db block on which the query works (indipendetly if they are found immediately in the buffer cache or must be read from disk) ?
Hope you can help me.
Thanks

Yes, the index is appearing on the dba_indexes table, however its state is 'UNUSABLE'.
It looks impdp takes its state from origin metadata, puts into destination, and even is not trying to rebuild it.
Of course, after running ALTER INDEX REBUILD its status was changed to VALID.
So, what's the point impdp tells about its state? It can be hundreds of unusable indexes, why it's not just rebuilding it?

Problems with accessing V$SQLAREA, V$SQL, V$SQLTEXT, and V$SQL_PLAN

Hi there,
I created a new user account and granted it dba.
I logged on to this account and I am trying to run select statments on V$SQLAREA, V$SQL, V$SQLTEXT, and V$SQL_PLAN, but I am getting
ORA-00942: table or view does not exist
00942. 00000 - "table or view does not exist"
However, I can get into these views with SYSTEM.
I loged into system and tried to grant

Clarification in V$SQL and V$sqlarea

Hi Gurus, I have a clarification in V$SQL and V$sqlarea. Is it possible to get the entire set of SQL commands that are executed or run for particular session irrespective of the number of commands that are executed during the session. And can this result be got in a text file.
thanks in advance.

Hello,
with execute dbms_system.set_sql_trace_in_session(session_id, serial_id, {True | False}) you can activate SQL tracing for a specific session. SQL Trace will generate a trace file in udump. With TKPROF you can format the output.
If you want to trace your session: ALTER SESSION SET SQL_TRACE = TRUE

V$sqltext & v$sqlarea

I am trying to view the SQL that is being passed to my Oracle 10g server from my .NET app. In a previous post I was told to use the v$sqltext & v$sqlarea views. Using sqlplus from the command line, I am able to produce the 1 line that I believe is the statement I am after. The statement is truncated after 1 line and I am unable to see more. I did try playing with the set command & also tried to find a gui sqlplus so the statement would simply scroll when entered. Is there a gui sqlplus for Oracle 10g? Can anyone offer any advice on how to simply view update, insert & select statements? Any help is appreciated.

Perfect. Downloaded, installed, works wonderful. I can finally see my query. Any ideas why the parameters being passed from .NET are not the actual values being passed into the query?
UPDATE "WHSTSTICKETS" SET "CUSTOMER_ID" = :CUSTOMER_ID, "RECEIVED_BY" = :RECEIVED_BY, "CALL_DATETIME" = :CALL_DATETIME, "AREA_ID" = :AREA_ID, "CLASS_ID" = :CLASS_ID, "STATUS_ID" = :STATUS_ID, "RESOLVE_DUE_DATE" = :RESOLVE_DUE_DATE, "RESOLVE_DATETIME" = :RESOLVE_DATETIME, "RESOLVER_ID" = :RESOLVER_ID, "DETAILS" = :DETAILS, "PRIORITY" = :PRIORITY, "SUBJECT" = :SUBJECT, "EMAIL_CC" = :EMAIL_CC, "ROOT_CAUSE_ID" = :ROOT_CAUSE_ID, "REGION" = :REGION, "EMAIL_CC_1" = :EMAIL_CC_1, "EMAIL_CC_2" = :EMAIL_CC_2, "EMAIL_CC_3" = :EMAIL_CC_3, "EMAIL_CC_4" = :EMAIL_CC_4, "EMAIL_CC_5" = :EMAIL_CC_5, "EMAIL_CC_6" = :EMAIL_CC_6, "EST_HOURS" = :EST_HOURS, "PQR" = :PQR, "PROJECT_ID" = :PROJECT_ID WHERE "WHSTS_ID" = :original_WHSTS_ID

SQL_FULLTEXT Column of v$sqlarea

All,
What do I need to do so that the full text stored in sql_fulltext column of v$sqlarea is displayed.
At the moment, when I run the following sql:

where sql_id='0n6x4f5kaaymb';
I get the output below:

Depending on the nature of your application, the size of your SGA, and how well you or your developers use bind variables, the number of statements is perfectly fine or really horrible. Like so many things in Oracle, it depends.
One of our databases has several hundred concurrent users, but they are all using a single application that uses bind variables everywhere and has a fairly limited range of funtionality. It has about 10,000 rows in v$sqlarea. Another database supports a dozen or so concurrent users using many related but different applications most of which have never heard of a bind variable. It has about 60,000 rows, most of them being multiple copies of various sql statements differing only by the literal strings used as predicates.

V$sqlarea encoding

I have plsql code looking something like that:
if v_state_flag = 'S' and v_next_query = 'Y' then
      PKG_COMMON.DEBUG ('GET_ADDRESS_LEVEL_LIST.30, fill o_state_list');
      -- kui #postal_flag = 'Y' ja #postalcode on antud, siis lisada klausel
      if v_postalcode_flag = 'S' and i_postal_code is not null then
         open o_state_list for
            select reg.CODE, reg.NAME from V_REGION_LANG reg
            where reg.LANGUAGE = PKG_SESSION.LANGUAGE_CODE
               and reg.COUNTRY = i_country
               and reg.REGION_LEVEL = 'STATE'
               and reg.CLOSED_TIME is null
               -- kui #postal_flag = 'Y' ja #postalcode on antud, siis lisada klausel
               and reg.CODE in (
               select r.REGION_CODE1 from REGION r, POSTALCODE p
               where r.COUNTRY = p.COUNTRY
               and r.CODE = p.REGION_CODE
               and p.POSTALCODE = i_postal_code
               and p.CLOSED_TIME is null
               );       View "v$sqlarea" shows this query as:
select * from v$sqlarea where
last_active_time > sysdate - 2
and sql_text like '%REG.CODE, REG.NAME%'
SELECT REG.CODE, REG.NAME FROM V_REGION_LANG REG
WHERE REG.LANGUAGE = PKG_SESSION.LANGUAGE_CODE
AND REG.COUNTRY = :B1 AND REG.REGION_LEVEL = 'STATE' AND REG.CLOSED_TIME IS NULL
;We have " :B1" in query, it stands for plsql parameter "i_country". But we have call to package function "PKG_SESSION.LANGUAGE_CODE" in v$sqlarea query- why wasn't this function replaced with ":B15" for example?
Why plsql parameters are replaced with ":B5" but package functions not?
Does the "PKG_SESSION.LANGUAGE_CODE" in query makes the query slower?

PL/SQL variables by default act as Bind Variables when you use them in SQL. But PACKAGE functions or standalone functions are not bind variables.
If you dont want the package name to appear in the SQL area then you need to change the SQL to use a bind variable.
Something like this
if v_state_flag = 'S' and v_next_query = 'Y' then
      PKG_COMMON.DEBUG ('GET_ADDRESS_LEVEL_LIST.30, fill o_state_list');
      my_value := PKG_SESSION.LANGUAGE_CODE;
      -- kui #postal_flag = 'Y' ja #postalcode on antud, siis lisada klausel
      if v_postalcode_flag = 'S' and i_postal_code is not null then
         open o_state_list for
            select reg.CODE, reg.NAME from V_REGION_LANG reg
            where reg.LANGUAGE = my_value
               and reg.COUNTRY = i_country
               and reg.REGION_LEVEL = 'STATE'
               and reg.CLOSED_TIME is null
               -- kui #postal_flag = 'Y' ja #postalcode on antud, siis lisada klausel
               and reg.CODE in (
               select r.REGION_CODE1 from REGION r, POSTALCODE p
               where r.COUNTRY = p.COUNTRY
               and r.CODE = p.REGION_CODE
               and p.POSTALCODE = i_postal_code
               and p.CLOSED_TIME is null
               );By doing this you execute the package function only once. But when you use it in a SQL directly you execute it for every row.

V$session and v$sqlarea is interpreting in different way

I am trying to run the below shell script on the linux box

here is the spool file content. v$session is interpreted as v a and v$sqlarea is interpreted as v b.
How can i fix this?

Because *$* is interpreted by Linux shell. So you need to escape it. I used to escape all $ with \$ but someone in another thread posted a lovely trick. Use this:

V$sql, v$sqlarea and v$sqltext

Hello,
Any idea how to isolate PLSQL objects calls from SQL statement in following views?
v$sql,
v$sqlarea,
v$sqltext
For e.g. I ran following query but it would also include SELECT statements. Whereas I only need PLSQL Calls.
select * from v$sql where upper(sql_text) like 'BEGIN%.%'
Is there any better way?
Thank you in advance for reading this post.
R

A select statement can include a pl/sql function call so you cannot exclude selects and search only the begin keyword.
You could join with DBA_OBJECTS, but is not very precise:
select *
from v$sql, dba_objects
where upper(sql_text) like '%'||object_name||'%'
and object_type in ('PACKAGE','PROCEDURE','FUNCTION');Max

Real explain plan differs from one in v$sqlarea

I have some more or less complex queries which I catch on runtime by reading v$sqlarea table to find sql with high cost..
but..
I found some highly costed sql, but when I run it through client ti see it's explain plan and execution time, it's much faster with very little cost
why?
am I wrong when I read v$sqlarea?
I'm using Oracle 11g R2

This is not at all surprising. Jonathan Lewis and many other have discussed this numerous times both in these forums, in books, in white papers, and in conference presentations.
That said ... you should be looking in gv$sql_plan.

Could see pending command in v$sqlarea

Hello,
Please see the command and output below :
SQL> select FIRST_LOAD_TIME,SQL_TEXT from v$sqlarea where users_executing > 0;
FIRST_LOAD_TIME SQL_TEXT
2005-11-11/16:45:50 SELECT * FROM ratl_oplog
2005-11-18/14:44:01 select FIRST_LOAD_TIME,SQL_TEXT from v$sqlarea where users_executing > 0
The first entry in the output is pending since 11th Nov...and I think this is reulting in performance problems in my database.
Can somebody suggest some way to solve this issue..??
Thanks, Rajeev

Hello,
first off all have a look at select * from v$session_longops;
To solve this problem alter system kill session.
