• Why I have two different execution plans for the same query on two different servers

  Hello everyone.

  I need your help to solve the problem quickly.

  In a nutshell, we have two servers that have the same version of Oracle RDBMS (11.2.0.4 EE). One of them for purposes of development and another is a production one.

  We have therefore two different execution plans for the same query executed on both servers. The only case of execution is OK and another is too slow.

  So I have to slow down the work of query using the same scheme to explain that young.

  Fence wire.

• explain plan for the same query diff

  Hi experts,

  Please, help me understand explain the plan.  I have tow Server (server and two server). The server are same table, even the type of database, even version Oracle (gr 11 (2), same operating system (linux Redhat 5.5) and same table and index.

  but when I explain the plan for the same query on the two server. I got diff--diff to explain the plan. reason it has different, according to my understanding, it should be same. explain please, I share the explain plan and lower indices for the two server.

• Configuration of the two of the same model data acquisition

  Hello, community of NOR.

  I'm an intern in mechanical engineering with experience in base with LabVIEW.

  I would like to speak to OR directly on this issue, but I don't have a service contract and my company wants me to understand this before you buy LabVIEW.

  I hope that someone has experience about my question, and I would be very happy to help.

  We intend on purchasing an expansion card for our acquisition of data (OMB-USB-2416), but unfortunately it is offline and no custom would not happen in time.

  So, I need LabVIEW to read voltage HAVE two of the same model of data acquisition, which would amount to about 30 channels.

  Is this possible with LabVIEW?

  Thank you.

  Measurement computing says that the "physical channels" dropdown list is automatically filled in once both devices are configured.

• Determine the maximum length of a column and its use in the same query?

  I would like to determine the maximum length of a column and use it in the same query. Is this possible? IE:
  
  SELECT RPAD (last_name, SELECT MAX (LENGTH (last_name)) + 5 FROM user, '-')
  OF the user.
  
  Thank you

  Welcome to the forum!

  Thank you

  Sure. You almost go in your message: a scalar subquery . Just put brackets around the subquery:

  SELECT      RPAD ( last_name
            , (
               SELECT  MAX (LENGTH (last_name)) + 5
               FROM    user_tbl          -- USER is not a good table name
              )
            , '-'
            )          AS padded_last_name
  FROM      user_tbl
  ;
  

  Scalar subqueries in SQL are like tape in your garage in canvas: they are used for thousands of different things and open, maybe 1% of them. Usually, there are better ways to achieve the same results, such as the analytical functions:

  SELECT      RPAD ( last_name
            , 5 + MAX (LENGTH (last_name)) OVER ()
            , '-'
            )          AS padded_last_name
  FROM      user_tbl
  ;
  

  Still another way is to make the subquery and then join his game as if it were a table of results:

  WITH     got_max_length     AS
  (
       SELECT     MAX (LENGTH (last_name))     AS max_length
       FROM     user_tbl
  )
  SELECT      RPAD ( u.last_name
            , m.max_length + 5
            , '-'
            )          AS padded_last_name
  FROM           user_tbl     u
  CROSS JOIN     got_max_length     m
  ;

  What you see is two of the same record in LR, but their records within each are different.  How can I combine these files so that they correctly see the architecture of my hard disk into a single folder?

  In addition, how to prevent this in the future?

  Thanks, Johan, I'll try.
  My first post for local oracle param, I got it 3 days ago. or I confuse my file params to oracle. (This problem continues from last week)
  Now I'm waiting still current oracle local params and these value is worse:

  Local:
  pga_aggregate_target 0
  SGA_MAX_SIZE 536.870.912
  SGA_TARGET 0

  I update the new oracle local params in my previous message.

  I'll try the update of these values, but I hope, my local oracle is not drop down :)

  Can't be worse...
  You have a parameter memory_target (and max_memory_target)? If so, you could add memory to these settings as well and only set pga_aggregate_target (no CMS or sga_max)

  My settings (on a test/dev/lab-box):
  System@oracle11 SQL > see the memory settings

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  hi_shared_memory_address integer 0
  whole big memory_max_target 3G
  whole large memory_target 3G
  shared_memory_address integer 0
  System@oracle11 SQL > show parameter sga

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  lock_sga boolean FALSE
  PRE_PAGE_SGA boolean FALSE
  SGA_MAX_SIZE large integer 0
  SGA_TARGET large integer 0
  System@oracle11 SQL > show parameter pga

  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------------------------
  pga_aggregate_target large integer 0

  This way I pushed things like Oracle by itself, memory allocation to everywhere where oracle needs him the most.

  If you notice the first column in the two outputs. It is sorted in sql server and no oracle.
  
  Why he behaves differently in oracle? Is there a way I can fix this problem in oracle?
  
  Thank you
  Jigs

  It is NOT a behavior "differently" in Oracle; you did not specify just an order that you expect of your results, so you'll get output in what order the fantasies of the database showing (ie. no guaranteed order). It is an artifact of the way the database chooses to collect the data and databases (or same sets of data within the same database) can and will most likely behave differently.

  Same SQL Server will not be guaranteed to always get your data in an orderly manner if you exclude the order by clause, even if you think that there always display the data in an orderly manner.

  Your solution is to add an order by clause, in the TWO databases, to force the order of the data output.

• The execution plan changes for the same query.

  Hi all
  
  This issue was raised before also, but still not able to find the real cause of this.
  
  Thread1:
  Re: Research of fragmentation of the table in Oracle 8.1.6.3.0
  
  Thread2:
  CBC latch and buffer busy await you on the same table.
  
  It comes, sometimes hammers server 100% CPU utilization with free latch and buffer busy wait events.
  
  We found a single query consumes high CPU usage that is run by different sessions.
  
  This query have two types of execution plans, where one is accurate and is not (its primary key hit index index no appropriate means present on the table)
  
  Because its primary key index hit repeatedly at various sessions, some sessions are powerful db file sequential read and a few sessions waiting buffer busy waits for event. Also during this time a few sessions waiting for latch free event.
  
  My doubt is how to sql even with different literal values execution plan changes and causes a prob.

  How to avoid this... why its different execution plan using (I mean bad index PK)
  
  Is it possible to avoid this?
  
  If any details please check out some of my previous post on this specific URL (above)

  My doubt is how to sql even with different literal values execution plan changes and causes a prob.

  Different literal values cause analysis difficult.
  Hard analysis includes the re-evaluation of the best path.
  Literal value is included in the assessment of the selectivity for the scan interval (log_seq >...)

  more the book of Jonathan Lewis which other threads, I believe that you already have.

  You must lower your CPU.
  Previous discussions, if the situation is still the same, it sounded like hard analysis particularly with this SELECTION against the NEWSPAPER plays an important role in that.

  How to avoid this... why its different execution plan using (I mean bad index PK)

  The points raised in the previous discussion remain valid.
  -Do you have access to this SQL to change?
  for example using bind variable or trick it if necessary due to problems caused by data as discussed in the previous thread.
  - Or you could it repoint the view to a view and a hint?
  -If a particular user makes this sql, could affect you cursor_sharing just for this user. If not, you should consider implementing pan-Canadian database.

  Oracle 8.1.6 still?
