Fragmentation of the table to find Oracle 8.1.6.3.0

• Truncate, but still have the fragmentation of the table?

  Hello

  We have just solved a performance problem, I guess that is because of the fragmentation of the table, but do not know how the fragmentation happened because the table is always truncated and recharged.

  I thought that TRUNCATE would always reset the HWM and fragmentation would not happen. Y at - there other possibilities?

  The work has always been less than 30 minutes. Recently, nothing is changed to any procedure, tables etc. - unconfirmed with maintenance DB s/n. Then the job runs up to 11 hours. By re-creating the table, the task runs from 11: 00 to 25mins. Note the work and the tables are years old.

  What could be the reason behind this please, ideas

  Thank you

  Amy

  Thank you all for your contributions.

  After a few days of investigations/tests with DBA, it is identified as not a problem of fragmentation of table.

  One of the additional queries has cost too much, the time elapsed for the sub query was 0.39 sec but saw 157 k lines, swipes the entire process super slow - window 8-11 hours.

  Did not understand why that truncate the table S and recreate the table S do somehow temporarily performance within 30 minutes well.

  Now, after the adjustment, it's up to 13 min, the cost is low 500 to 14. Not perfect for 157K load, much better than before - still space to rewrite the procedure.

• fragmentation of the table

  Hi all

  Oracle 8i (8.1.7)

  Solaris

  Name of the table: activity

  size: 22GB

  Actual data: 10 GB

  Wasted space: about 12 GB

  having 7 index

  Here is my intention to remove the waste space what is the best method?

  plan do sql > alter table activity colsec;   This is the good method or what I need to do something...?

  If I allow the movement of the line, what will be the impact?

  Thank you

  Mike.

  plan to release unused space in the table using activity below methods... I mean what method will be the best to do online (hours not... his production company,...), and including a quick and the better... Please advise.

  Method 1:

  SQL > alter table activity merge;

  Method 2:

  SQL > alter table activity release unused space.

  SQL > alter index acivity_idx_1 free unused space.

  Thank you

  Mike.

  This will depend on the ability of the system... I hope it using your legacy software/hardware... ... better sure .not to .test it on the test machine.

  Merge and methods 'remove unused space allocation"will serve to free up space on the db when you those who shot, but they are his own.

• How to check the table reused in oracle 10g space?

  Hello..
  
  Of my system, I see table size keep growing event the deletion request is running. Because of this, I would like to check either the allowed oracle to reuse space table or not? If not then how can I enable it?
  
  
  Please help me...
  
  
  Thank you
  Balleur

  You can use dbms_space.space_usage to check for free space.

  Reuse of the space will depend on whether you use MSSM or SAMS, PCT_FREE, PCT_USED and the way in which new data is inserted?

  You can reduce or move the table and rebuild the index to reclaim space.

• Name of the table to find the workbook columns

  Hello
  
  I'm working on an implementation project legacy 11.5.10 and discoverer 4 version R12 system. I'm looking in the discoverer workbooks and I need the name of the table to determine the COLUMNS in a workbook.
  Any help is appreciated.
  
  Billa

  Hello

  Unfortunately, this information is not available in the EUL. The workbooks are stored in the EUL4_DOCUMENTS table in a column of type LONG. It uses a binary format and means that you can not query the structure of the workbook.

• Comparison of the tables to find items that differ - JS?

  I think I have my all wrong logic.

  I'm trying to compare two tables, with the result that I get a new array with the elements in the first, which do not appear in the second.

  Array1 - a, b, c and d, e

  table 2 - a, b, c

  new table must contain d, e

  THIS IS WHAT I'M TRYING...

  -Function to get graphics-

  function getGraphicsFunc()

  {

  -tests of graphics in library-

  MyLib = app.libraries.item var (0);

  the list of graphics in the library

  var libGraphicList = mylib.assets.everyItem () .name;

  Alert (libGraphicList);        <-- IT WORKS very WELL

  -Get a list of all the charts for CID on Pulse_OPI-

  var graphicFolder = the folder (basegraphpath + lastdigits + "/");

  var theGraphics = graphicFolder.getFiles ();

  var allGraphics = [];

  a content ID match files

  for (i = 0; i < theGraphics.length; i ++)

  {

  Assuming 8 sequence of numbers is a static number.

  You can also use grep to match 8-digit >

  If (theFiles [i]. Name.match(/^\d{8}/);

  If (theGraphics [i].name.indexOf (adCID) == 0)

  {

  allGraphics.push (theGraphics [i] .name);

  }

  }

  Alert (allGraphics);        <-- This WORKS FINE - the following comparison is the problem...

  Compare graphic tables to see which are NOT in the library

  var missingGraphics = [];

  for (j = 0; j < allGraphics.length; j ++)

  {

  if (toString (libGraphicList).indexOf(allGraphics[j]) is-1)

  {

  missingGraphics.push (allGraphics [j]);

  }

  }

  Alert (missingGraphics);        <-- THIS ALWAYS PRODUCES THE SAME "MISSING GRAPHICS" EVEN IF THEY ARE IN the INDL

  var graphicsFound = (missingGraphics.length)

  Alert ("On" + graphicsFound + "graphics found and imported into the library")

  }

  Many thanks in advance and Merry Christmas everyone...

  Which if statement says:

  If (String (libGraphicList). IndexOf(allGraphics[j]) is-1)

  or toString is a function you wrote, but not included?

  I would have probably used:

  If (libGraphicList.Join("|"). indexOf(allGraphics[j]) is-1)

  I thought of doing it this way. It is probably that the calculation of the loop by the string before the declaration and comparing with that.

• How to decrease the level of fragmentation of a table.

  Hi all
  
  There is a table in my database of production.
  His version is Oracle 10 G (10.2.0.1.0)
  
  (i) its size is 26 GB with level of fragmentation.
  (II) it has more then 48 crores of lines.
  (III) its size is 20 GB without fragmentation level. (Up to 6 GB of unused space is wasted).
  
  Here are my doubts about the above points.
  
  (i) how to reduce the level of fragmentation of the table.
  
  (II) if there is a way to reduce the level of fragmentation, how long it will take to perform the particular activity in order to reduce the level of fragmentation.

  Move the table into a new table space and rebuild the indexes.

• compression of the table

  Hi guys,.

  I try to compress the table. Then I connect via Oracle SQL Developer > right click > storage > compress. All right.

  But does not change the size of the table.

  Y at - it a command to say: 'start compression for my table1 now?

  More than 50,000 rows in my table.

  Thank you!

  Compression of the data in a table does NOT change the size of the table.

  It increases just the available space in the table.

  Oracle shall never voluntarily return disk space after that she acquired it.

  Oracle is designed to reuse free space.

• How to get a list of the tables more fragmented in Oracle?

  Is there a SQL on how to get a list of the tables more fragmented in the Oracle DBMS?

  Update the statistics on the table and try this, you should see very fragmented tables upstairs with high wasted_space.

  select table_name,round((blocks*8),2) "size (kb)" ,
                              round((num_rows*avg_row_len/1024),2) "actual_data (kb)",
                              (round((blocks*8),2) - round((num_rows*avg_row_len/1024),2)) "wasted_space (kb)"
  from dba_tables
  where (round((blocks*8),2) > round((num_rows*avg_row_len/1024),2))
  order by 4 desc
  

  I changed the query a little because the ORDER BY will not work if we concat | ' Ko ' with the column because this makes the output a character column data.
  And added a WHERE condition to see that these tables where the total size is greater than the actual size of data.

• Oracle DB 11.2.0.4: Impossible to activate the table lock after having stopped it

  Hello

  I use Oracle Database 11.2.0.4.

  After reading the documentation on how to prevent unwanted table DDL statement.

  I found a way to do this in by issuing 'edit the table < table_name > disable table lock'.

  Turn it off doesn't work, however I can not re - activate.

  The error message is:

  ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired

  I want to activate the lock, because I need to add new columns to this table.

  I was digging on several threads that have the same problem as mine. But none of them gives any acceptable solution.

  Impossible to activate the table lock after disablng it

  ALTER table enable table lock blocking

  However, a poster responds by quoting the documentation that says: (Note: I can't find what doc says)

  'Specify the TABLE LOCK ACTIVATE to activate the table locking, allowing operations on the table DDL. All currently process transactions must commit or roll before Oracle database allows table locking. »

  
  

  By the way:

  1. the table is mine and nobody knows there are (therefore, it would be just me which undoubtedly make any DML at it, and I did not).

  2. I've disabled the lock table months ago and tried to turn it back on because I want to add the new column to the table.

  
  

  It means that I have to wait for that "ALL transactions running" happening on the current scheme being validated or cancelled?

  The table itself is located on the stops and never schema of production on which transactions take place continuously.
  

  
  

  Is it true that Oracle expects all execute transactions? Is it known bug?

  Why would Oracle wait as all transactions which has nothing to do with the underlying table?

  Is there no workaround solution to solve this?

  
  

  Note:

  I tried to deactivate - activate the table locking on the development database (which has less transaction) and it works fine.

  
  

  Kind regards

  Your best option might be suspended from the database. If it is an application of type OTP, it must suspend in some secinds, do your DOF, then get out. Your users should not notice. I have described the mechanism here,
