• Tablespace TEMP fills and then see ORA-04031

  Hello

  Database Oracle version: 11.2.0.3 Linux

  "KGLH0 ^ bac435f8 kglHeapInitialize:temp ',' ')" error. We can assume that because the TEMP tablespace was full for the sort used oracle shared pool/memory for sorting operation and has caused the depletion of the space in the shared pool.

  Please answer.

  Hello

  NO, because the shared pool is not used for sorting but used for analysed maintenance sqls, pl/sql code information and data dictionary. Please read more about shared pool Memory architecture - 11 g Release 2 (11.2)

  > ORA-04031: unable to allocate 32 bytes of shared

  This means that you can set the Shared pool.

• cancellation by default and temporary tablespace issue

  (Oracle 10g)

  Sorry, I don't have access to a database at the moment to try this out, so I ask here.

  If we create these, the system gets used.

  (1) but if we create these and you do not specify a default undo tablespace or default temporary tablespace - what this means system will still get used?

  (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.

  Hello

  I'll try to be clear...

  (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.

  Test:

  SQL> show parameters undo
  
  NAME                                 TYPE        VALUE

  SQL> rollback;
  
  Rollback complete.
  
  SQL> select * from cdc.tab_dummy;
  
  no rows selected
  

  (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.

• Undo and temporary tablespace structure

  I have a silly question.  Suppose a block contains 100 lines and access 1 row, then oracle will bring the entire block (100 lines) in the buffer cache and 1 row to return.

  What is the case though

  a. I'm updating 1 row, undo tablespace will pre image of the block?

  b. my satisfied request 1 row block and A complete block will be in the temporary tablespace.

  a. No. UNDO holds vectors of change, not pre-image of the [whole] blocks.

  b. TEMPORARY tablespace is used for sorting and certain other operations. Space TEMP several times in memory is sufficient, and the temporary tablespace is never touched. Temporary segments contain data specific to your application and not the full original block. A query cannot to use temporary space.

• 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.

• Disk Cleanup stalling on temporary files for more than 3 hours and eat memory!

  So, whenever I checked my C drive I get different numbers on how much space is left. I deleted 45 GB (sent to remove trash and Perm.) data I didn't need and I always as much as before, if not less. I then tried to run the disk cleanup for that drive and it keeps blocking on "files temporary scanning", which since more than 3 h and no other programs other than windows base and Trend Micro are running and system keeps using more memory.

  This all started a few days after a windows update.

  It is using 25% CPU usage... as to what it is I don't have any idea. I've used it before and it scanned in less than 45 min.

• Tablespace with a data file name in double and the directory added

  Version Oracle 11.1.0.7
  AIX platform
  
  I have exactly the same directory for the tablespace even a tablespace with 2 files with exactly the same name.
  
  I don't think it was possible for Oracle create two data files in the same directory with exactly the same data file for a tablespace name.
  
  The difference between the two seems to be the sizes - one is 10G, the other is 10 m autoextend on but with maximum size is equal to the size of create.
  
  It is not possible to table either both are full.
  
  Please notify.
  
  Thank you.

  You have a character that is hidden in the name of the file. Use ls for your operating system which shows the special characters (ls - lb or something, man ls).

• 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.

• 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;

• 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.
