Oracle XE TEMP tablespace issue

• Using bulk collect into with assistance from the limit to avoid the TEMP tablespace error run out?

  Hi all

  I want to know if using bulk collect into limit will help to avoid the TEMP tablespace error run out.

  We use Oracle 11 g R1.

  I am assigned to a task of creating journal facilitated for all tables in a query of the APEX.

  I create procedures to execute some sql statements to create a DEC (Create table select), and then fires on these tables.

  We have about three tables with more than 26 million records.

  It seems very well running until we reached a table with more than 15 million record, we got an error says that Miss tablespace TEMP.

  I googled on this topic and retrieve the tips:

  Use NO LOG

  Parallel use

  BULK COLLECT INTO limited

  However, the questions for those above usually short-term memory rather than running out of TEMPORARY tablespace.

  I'm just a junior developer and does not have dealed with table more than 10 million documents at a time like this before.

  The database support is outsourced. If we try to keep it as minimal contact with the DBA as possible. My Manager asked me to find a solution without asking the administrator to extend the TEMP tablespace.

  I wrote a few BULK COLLECT INTO to insert about 300,000 like once on the development environment. It seems.

  But the code works only against a 000 4000 table of records. I am trying to add more data into the Test table, but yet again, we lack the tablespace on DEV (this time, it's a step a TEMP data)

  I'll give it a go against the table of 26 million records on the Production of this weekend. I just want to know if it is worth trying.

  Thanks for reading this.

  I really need check that you did not have the sizes of huge line (like several K by rank), they are not too bad at all, which is good!

  A good rule of thumb to maximize the amount of limit clause, is to see how much memory you can afford to consume in the PGA (to avoid the number of calls to the extraction and forall section and therefore the context switches) and adjust the limit to be as close to that amount as possible.

  Use the routines below to check at what threshold value would be better suited for your system because it depends on your memory allocation and CPU consumption.  Flexibility, based on your limits of PGA, as lines of length vary, but this method will get a good order of magnitude.

  CREATE OR REPLACE PROCEDURE show_pga_memory (context_in IN VARCHAR2 DEFAULT NULL)

  IS

  l_memory NUMBER;

  BEGIN

  SELECT st. VALUE

  IN l_memory

  SYS.v_$ session se, SYS.v_$ sesstat st, SYS.v_$ statname nm

  WHERE se.audsid = USERENV ('SESSIONID')

  AND st.statistic # nm.statistic = #.

  AND themselves. SID = st. SID

  AND nm.NAME = 'pga session in memory. "

  Dbms_output.put_line (CASE

  WHEN context_in IS NULL

  THEN NULL

  ELSE context_in | ' - '

  END

  || 'Used in the session PGA memory ='

  || To_char (l_memory)

  );

  END show_pga_memory;

  DECLARE

  PROCEDURE fetch_all_rows (limit_in IN PLS_INTEGER)

  IS

  CURSOR source_cur

  IS

  SELECT *.

  FROM YOUR_TABLE;

  TYPE source_aat IS TABLE OF source_cur % ROWTYPE

  INDEX BY PLS_INTEGER;

  l_source source_aat;

  l_start PLS_INTEGER;

  l_end PLS_INTEGER;

  BEGIN

  DBMS_SESSION.free_unused_user_memory;

  show_pga_memory (limit_in |) "- BEFORE"); "."

  l_start: = DBMS_UTILITY.get_cpu_time;

  OPEN source_cur.

  LOOP

  EXTRACTION source_cur

  LOOSE COLLECTION l_source LIMITED limit_in;

  WHEN l_source EXIT. COUNT = 0;

  END LOOP;

  CLOSE Source_cur;

  l_end: = DBMS_UTILITY.get_cpu_time;

  Dbms_output.put_line (' elapsed time CPU for limit of ')

  || limit_in

  || ' = '

  || To_char (l_end - l_start)

  );

  show_pga_memory (limit_in |) "- AFTER");

  END fetch_all_rows;

  fetch_all_rows (80000);

• High TEMP tablespace usage

  In our DB Oracle 11 GR 1 material, we are facing a problem of use high temporary tablespace...

  Currently, I did the size of tablespace temp that 200 GB, but im afraid, that will be used too much upward.

  My concern is

  1. when I checked in the sessions of $ gv, gv$ sql table, SQL not runs, which uses temporary spaces, but the current use of the stand space temp near 75%, i.e. 175 GB!

  I read on other forums that temp space may not immediately released. But 175GB is too much in my opinion

  I tried the sub queries that will tell which session uses the amount of temporary space. But normally the same query will run and 97 GB of temp tablespace is sufficient to run the query.

  But why last 2 days using 190 GB of temp tablespace.

  Can find us why all of a sudden begins to use the temp tablespace more.

  There is no change in the query.

  Excessive temp space is more often associated with inaccurate estimates (too weak) to sort and hash operations.

  Solve the excessive use temp space is usually a two-step process:

  1. find SQL with excessive temperature, get the metric of effective implementation of the enforcement problem, look for estimates inaccurate when comparing estimates cardinalities real vs.

  2. once the estimates are correct, if the temp space usage is always high then consider sizing of manual activities.

  Although the use of temporary space has increased sharply, then either you had a sudden increase in the data or you have had a change suddenly in the execution plan.

  Use the AWR and ASH to study, subject to the license.

  If it is a change suddenly in the execution plan, then you have the easy option to use a plan sql database or a sql profile to lock in an older implementation plan with a lower use of temporary space.

• warning when the temp tablespace is full

  Hi all
  
  on my DB 11.2 comes from time to time situation running the full temp tablespace. It sucks just two seconds and when the dba is not noticed, the tablespace is already almost vacuum. Is it a way somehow to create as a "reminder - notify" triggering te when the temp tablespace for us will say a lot of 70%.
  That "remember - notify" runs the sql statement look in the parameter $ v, process$ v, v$ sort_usage, v for sessions of problem $session.
  Thanks and rgds,

  You do not use dbcontrol?
  You can easily configure dbcontrol to do this, or use the package dbms_server_alert directly.
  The starting point is as usual... reading documentation.

• Temp tablespace - why so great?

  Tablespace Temp (size 6 GB) is twice the size of my data and combined index tablespace. I'm running in space issues and wonder it is possible to resize this tablespace or perform another action to prevent the temp tablespace becomes relatively important?
  
  Thanks in advance.

  Hello...

  Aman said, quite rightly, tablespace temp behavior is changed now. You have to watch the sort_area_size or the PGA(>=9i). The option you have now is

  1. create a new tablespace (TEMP2) temp say size of 512 MB tempfile,

  2 assign as the default temporary tablespace.

  3. remove the previous (TEMP1) temp - drop tablespace tablespace temporary temp1 including content;

  4. create the tablespace temporary temp1 tempfile ' / temp file location previous ' size ' ' reuse;

  5. default assign temp1 as the temporary tablespace.

  6 drop tablespace including contents temporary temp2;

  7. the next time when necessary, you can reuse this tempfile 512 MB for the same process.

  You can move a cycle always use this procedure.

  Note do NOT USE the CLAUSE AND DATA files IN the DROP STATEMENT, SO THAT THE DATA files CAN BE REUSED.

• Full Temp tablespace

  Hello
  
  The tablespace temp on our database suddenly began to fill.
  
  It has 4 GB of ram on your server, about 1.3 G is used by the operating system,
  , 1.7 bg the sga and 700 MB by PGA target parameter.
  
  We use the DSO, then the sort_area_size parameter does not come into play.
  
  All ratios are fine, but once the temp tablespace is almost full, things grind to stop.
  
  Someone at - it advice on the best way forward.
  
  I put statspack to run at the time.
  
  I appreciate ram is low, but I am confused as to why he suddenly began to occur.
  
  Thanks for reading.

  PGA_TARGET is a target.

  fixed lines 200
  Select * from v_$ pgastat;

  and look at the maximum used.

  There are also counselors, that you can watch in the views or dbconsole (if permitted), you can watch advice of the pga and pga memory utilization details. If you do a lot of executions multipass, which would slow and use a lot of temp. Temp tends to stay fully, docs of MOS and comments here that explain it.

  Adds the numbers you have validated, looks that you run right up to the border in normal times, a little more use of the user and you jump off the cliff. You may need to reduce your sga. How many users are using a shared server, what happens to change things?

• Temp tablespace

  Hi all
  I have a question here regarding the temp tablespace. I googled a bit and the documentation to understand some of the temp tablespace digital also searched. I got to know this temporary tablespace default cannot be deleted, unless you create a temp tablespace, so if we then deletes the temp in os level data files will happen (will be system tablespace becomes the temp tablespace?). In the case of other tablespaces if we drop the operating system level data files, then it will throw error during the startup it will show as the data files is not found and recovery in necessary... when that happens in case temporary files? It will throw an error? I also read that recover the temp tablespace is not possible and only a drop/recreate is possible is that true?

  There is only a temporary tablespace that can be set for the entire database. If this temporary tablespace file is deleted, it won't effect the database works as temporary files will not be part of the recovery process. In the absence of temporary storage space, system temp segment would start getting used by users as well. If you have lost a temporary file, when you start using it, it would lift the error that the file is not there. There will be no message you demonstrated that if the file is deleted explicitly.

  No, you can't rule out the space one tablespace to another because they use different files.  TEMP uses tempfiles, storage of data use data files and never the two are irreconcilable.  It is not like to shovel mashed potatoes, one plate to the other. storage spaces are physically separate entities.

  I support the opinion that you consume space TEMP at an "alarming rate" because you misspelled, poorly performing queries.  Yes, it's a data warehouse, but overnight batch process to repopulate this warehouse are not collected statistics?  A question you have run 11.2.0.1, the base of the 11.2 version, because it is quite buggy with some of these bugs related to statistics and optimizer.  You should, if possible, at least 11.2.0.3; 11.2.0.4 would be better.  I came across a nasty bug with 11.2 where the columns of unique, non-null would generate histograms of frequency numbers unnecessary.  Of course these histograms wreaks havoc on the plans because the optimizer uses these "fake" numbers  Of course, some of these could be attributed to badly written queries (and 'canned' queries from purchased applications are usually at fault if the app was designed to be "independent of the database".  If the seller does not use the DBMS-specific features and language extensions, that it goes without saying the queries more complex performing very well.

  Rather than trying to "goose" space it TEMP that you need to know what is consuming space and see if it can be fixed.

• cancellation by default and temporary tablespace issue

  (2) what happens if we specify cancel default and temporary storage spaces, to give the user a quota on these or the user automatically uses?

  Thank you.

  (A) to CANCEL, Yes, SYSTEM is used but a few transactions more tablespace SYSAUX & SYSTEM are permitted.

  operations on other storage space you need for an UNDO tablespace configured.

  (B) for TEMP, depends on:

  At the time of creation of database:

  IF = LMT SYSTEM THEN

  you have to specify a temporary tablespace

  ON THE OTHER

  the SYSTEM tablespace can be used as temporary tablespace

  END IF

  Doc http://docs.oracle.com/cd/B19306_01/server.102/b14220/physical.htm#i10741

  (2) what happens if we specify cancel default and temporary storage spaces, to give the user a quota on these or the user automatically uses?

  (A) to CANCEL,

  No, this storage space is for the feature "Internal (read consistency, etc.)" and you don't have to worry about the users quota.

  You can query the view dba_undo_extents separate owner and you can see that all extensions are owner of SYS.

  You can test it to create a new user with any quota on undo tablespace.

  (B) for the TEMPERATURE,

  No, this storage space is for the feature "in-house (sort operations, etc.)" and you don't have to worry about quotas users

  You can test it create a new user with any quota on the temporary tablespaces, performing a sort of big or creating an index.

  Thank you.

  Kind regards
