  SAMS - Oracle FAQ

• waiting on a free freelist

  Hello
  
  If t1 and t2 are waiting for a freelist become free and t1 began waiting 1, t1 will have access to it first?
  
  Thank you

  OK, well, because I think that any answer to this question leads to a lot more questions, I'll recommend you read book excellent in Stephan Haisley, available on MetaLink, sorry available on MOS, as Doc ID 157250.1. (Assuming that you can get into MOS and make it work!)

  Then keep in mind, the free list management is endangered of the door. With SAMS, free lists are no longer used to manage the blocks with free space. In the long term, it may be more practical to spend the time to understand how the SAMS.

  Hope that helps,

• freelists is LIFO?

  Jin
  
  I read the following white paper:
  
  http://BBS.wisky.org/doc/internal.docs/freelist%20Management%20with%20Oracle%208i%20.PDF
  
  Here, he says:
  
  "All types of freelists are implemented as a simple linked list using a mechanism of last-in first-out.
  
  Now assume that we just a free list of Master and no process lists for free (and I guess if we have no free lists of process, can we have free Transaction lists?). That master free points list data block 5 and 5 points to the data block 7 data block, then the main free list will point to the data block 7 (because it points also to the tail). Now let assume us a new data block, the 100 block of data, becomes available. This block of data 7 now pointing to it, like the master list of free in the segment header. Now let say us that we had to do a lot of inserts. This means that a transaction will go to the MFL, look at the tail, go to the data block 100 and start making inserts so that it is the first to leave the free list? If so, what is the logic behind this? is it because this block of data is "hotter" than the others and is more likely to be in the database buffer cache? or is there a different reason (s)?
  
  Thank you
  

• How does Oracle 'choose' a block of free data of freelist?

  Hello
  
  We could have 10 blocks on the freelist, all empty. How Oracle will begin to be inserted in these? Will it be by choosing one, he fills, before moving on to the next, or is this a case of many blocks being inserted at the same time?
  
  Thank you

  This document gives a reasonable explanation.

• Error on blue screen Windows 7 x 86

  Hello, I had a lot of problems with my laptop. The technical support guy said that my HD was done, so he sold me a new one, with Windows 7 x 86 (before I had the x 64), and my cell phone was OK for a while.

  Hi Laury.

  You say that the object exists, but you check its executable?

  https://docs.Oracle.com/database/121/GEORS/release_changes.htm#GEORS1382

  I guess that with the release of 12 c, Oracle wish you to specifically take action showing that you have a license Oracle Spatial.  Otherwise you can not use the georaster with just the license locator object.

  See you soon,.

• What is the syntax to create segments?

  Hello

  segment can be created manually as table space? If Yes, what is the syntax to create the segment?

  Concerning

  The create table statement has a storage clause that is part of the clause of physical attributes.

  These clauses to define options for the creation of segment/measure. If you do not specify the storage clause, then the tablespace-level settings are used.

  Documentation of the CREATE TABLE statement

  Physical properties: https://docs.oracle.com/database/121/SQLRF/statements_7002.htm#i2126711

  {Heap_org_table_clause BUNCH [segment_attributes_clause]

  | INDEX index_org_table_clause [segment_attributes_clause]

  | External_table_clause EXTERNAL

  | USER_TABLES { KEEP |} RECYCLE | DEFAULT }

  | FLASH_CACHE { KEEP |} NO | DEFAULT }

  | ENCRYPT

  } ...

  )

  However, the create table statement lets you not create segments or extensions directly. New extensions are to be created initially (when the table is created) or later, when more space is needed for the table, usually after several insertions that filled the original measure.

  Also remember that SQL is a language of generation 4. But there is no need to go into details such as the management of use or storage. All that and managed by the RDBMS.

• SNA/ora_rowscn issues

  Hi all

  I was reading AskTom and he talked about the clothing of the SNA at some point.  If this is the case, then how great the RCS measure up until it wraps?  Where is stored the film count?

  On imports, ora_rowscn on the data in the table will get SNA SNA DB and not what has been exported?

  The only use of the CPN in a datapump file would be used for flashback_scn? Right?

  Thanks for all replies.

  All, Woody would have already seen this, but Tim Gorman posted an answer to this same question on Oracle-L, which explains the operation of the base of SNA and rap as well as some interesting facts

• Analyze seems to work better stats of DBMS

  I know this question has been asked thousands of times in different contexts, but this is a very confusing topic:

  I have done a lot of googling and analyzed through the docs, but still not found the answer. Recommendation Docs oracle since version 9:

  
  

  Oracle Corporation strongly recommends that you use the DBMS_STATS package rather than ANALYZE to collect optimizer statistics. This package allows you to collect statistics in parallel, collect global statistics for partitioned objects, and refine your collection of statistics by other means. In addition, possibly cost-based optimizer uses only statistics that have been collected by DBMS_STATS . For more information about this package, see Oracle9i supplied PL/SQL Packages and Types reference .

  However, you must use the ANALYZE instruction rather than DBMS_STATS for the collection of statistics that are unrelated to the optimizer based on costs, such as:

  • Use the VALIDATE or LIST CHAINED ROWS clauses
  • To collect information on the blocks not freelist

  I'll try to post a test in most case this post earlier, because I can't post the plans exec real reason policies internal, but here's what I've noticed so far:

  Oracle 11.2.0.1.0 - Windows Server 2012 R2 64 bit

  -Memory settings increased Oracle, enabled WMA and restart of the database;

  -'Place' system statistics collected (dbms_stats.gather_system_stats), to let the Oracle knows that he has to work now;

  -Statistical collected schema (dbms_stats.gather_schema_stats);

  At this point, always kept users have reported performance issues. By examining some queries concerned, I found that there was a lot of full table scan (but yes, all the indexes were available and stats must be updated after stats diagram, please correct me if I'm wrong). So I ran dbms_stats.delete_schema_stats to remember his stats manually in analyse (cannot remember the paper at the moment, but I read, it is not a good idea to mix his stats with DBMS and analyze simultaneously), after after analysis completed, the cost overall reported 125 (before it was 400), but still a few tables running full table scan , so I remove the statistics for a specific table involved in full table scan, we'll call it 'A' and execution plan now opted for table access by index rowid and the cost for this stage went from 30 to 5, but know the overall cost has increased from-800 to 2000...

  So my main questions are:

  Anyone who works in a specific environment / db analyze where only worked / benefit show?

  Can it be dictated by modeling data / design? Whether or not DBMS / analyze will be a better option?

  What other steps can I take to isolate the problem?

  Is it necessary to clear the shared pool before collecting statistics, as it is sometimes possible to see immediate change to explain the release of the plan?

  Suggestions / corrections will be appreciated.

  Thank you.

  Guilherme, simply upgrade you your database?  I ask because the performance doesn't just normally in all areas except a major problem happens.  You get answers better when the full story is presented.  The main reason I ask is when you move a version of Oracle to an another treating CBO many changes come into play as with 10g on default DBMS_STATS to collect histograms while 9.2 no histograms were collected by default.  The sudden addition of histograms in the equation has burned more than a shop, while others barely noticed.

  - -

  Back on Oracle 9.2 we had better results using ANALYZE instead of DBMS_STATS. However, we started to use DBMS_STATS with our upgrade to 10.2.  We had only to give some queries immediately after the upgrade.

  - -

  If you recently upgraded you should be re-assembled all the statistics of objects as part of the upgrade.  Check your current settings of DBMS_STATS.  I recommend that you start with the default values of Oracle in all areas and keep the default values.  If you have any items where your plans get bad, you can change the settings on a basis of object level which is a nice feature because if you want to disable the histograms on a specific object or change the number of buckets used with the object.

  - -

  If this database has been used some time and performance went all of a sudden jar and then using ANALYZE instead of DBMS_STATS is not the right solution.  In this case, identify any changes to the system that were made as the parameters of database changes, the new application features enabled, etc...

• DBMS_DATAPUMP.metadata_remap - a matter of REMAP_TABLE.

  I want to export SCOTT. DEPT table and imports than HR. DEPT_HR with constraint. I'm using DBMS_METADATA. METADATA_REMAP with REMAP_SCHEMA (to change the schema anme) and REMAP_TABLE (to change the name of the table). I don't know where I am getting the error. It seems that REMAP_SCHEMA is changing all the names of schema successfully, but REMAP_TABLE does not change the name of the table on the constraint. So constraint is not be created. Is there another workaround solution? Here is a small proof of concept:

  If you look at the failing sql code, it is clear that the name of the table in the constraint definition has not changed, but the DEPT_HR table is created in the HR schema without constraint. What's not here?

  Hello

  This is a bug in 11.2.0.1 I think - please this Ref

  Oracle Support Document 1609238.1 (REMAP_TABLE on IMPDP FAILS WITH ORA-942) can be found at: https://support.oracle.com/epmos/faces/DocumentDisplay?id=1609238.1

• Lob Index DDL

  Hello

  I have developed 1 application where in i Ran SQL advisor tunning to grant some queries and it created many clues.

  So now I have to rename these indexes (LOB) to something like table_name_column name so I need to get the metadata in order to check the columns these lob indexes are cerated

  But when I ran get ddl statement I do not get the names of columns on which these lob indexes are created.

  Example:

  SQL > select dbms_metadata.get_ddl('INDEX','SYS_IL0000113826C00055$$','XXI') from double;

  DBMS_METADATA. GET_DDL('INDEX','SYS_IL0000113826C00055$$','XXCEMLI')

  --------------------------------------------------------------------------------

  CREATE A UNIQUE INDEX "XXI". "" SYS_IL0000113826C00055$ $' TO 'XX '. "" (tbs1_MV).

  PCTFREE, INITRANS 10 2 MAXTRANS 255

  STORAGE (INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645)

  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1

  USER_TABLES FLASH_CACHE, CELL_FLASH_CACHE DEFAULT DEFAULT)

  TABLESPACE "XXI_D".

  PARALLEL (INSTANCES OF DEGREE 0 0)

  DBMS_METADATA. GET_DDL('INDEX','SYS_IL0000113826C00012$$','XXCEMLI')

  --------------------------------------------------------------------------------

  CREATE A UNIQUE INDEX "XXI". "" SYS_IL0000113826C00012$ $' ON 'XXCEMLI '. "" (tbs1_MV).

  PCTFREE, INITRANS 10 2 MAXTRANS 255

  STORAGE (INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645)

  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1

  USER_TABLES FLASH_CACHE, CELL_FLASH_CACHE DEFAULT DEFAULT)

  TABLESPACE "XXI_D".

  PARALLEL (INSTANCES OF DEGREE 0 0)

  These indices are those that Oracle uses to find the content of the LOB column in the LOB segment when they are stored offline.  They are created and managed automatically by Oracle when you create a LOB column.  There is no need to change the names for those since you'll never use them, only Oracle internally.  In fact, I'm not entirely sure if you can change the name without breaking your BUSINESS.

• Reuse of blocks released upward in partitioned table

  Hello world

  I have a database creates a new partition and after a certain retention counter old partitions are deleted. This is done every day. We had some problem sometime before, so we disabled the partition drop script until it is revised for the partitions are not deleted for now. But we're going to delete all the files in the old partitions on a daily basis so that later, when we allow rear drop partition script it will not push the system.

  Now the problem is though that we delete the lines of the old partitions that continues to increase the size of the storage space, which means that it does not use the freed block. Please correct me if I'm wrong here, to my knowledge when the records in a table is removed the blocks going to the freelist for subsequent data inserts.

  The method above does not apply to the partitioned table is? If the space is released only if the partition is deleted? Thank you for you're your time and your answers. Very much appreciated.

  Database: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0

  OS: Oracle Solaris 10 SPARC 64 bit

  If possible, you should use TRUNCATE so that high tide is reset. It will be much faster to delete lines.

  What PROBLEM you encounter who pushed you to 'disable' the drop?

  Now the problem is though that we delete the lines of the old partitions that continues to increase the size of the storage space, which means that it does not use the freed block. Please correct me if I'm wrong here, to my knowledge when the records in a table is removed the blocks going to the freelist for subsequent data inserts.

  Correct - but only "freelist" will NOT be used for removable direct-path.

  My guess is that your new data every day are INSERTED in BULK. If, then Oracle just formats new blocks and fills them directly and does not use the free list.

  Do you use inserts of direct-path for new data?

  How can I export index partition (DDL)?

  For example:

  PARTITION BY RANGE (ID) INTERVAL (1)  (
  PARTITION "XXXXX"  VALUES LESS THAN (1)

  TABLESPACE "XXXXXXXXX"   )   ;
  

  Thank you!

  How can I export index partition (DDL)?

  For example:

  1. PARTITION BY INTERVAL OF THE RANGE (ID) () (1)
  2. PARTITION 'XXXXX' LOWER VALUES (1)
  3. CREATION OF IMMEDIATE SEGMENT
  4. PCTFREE, PCTUSED 10 0 INITRANS 1 MAXTRANS 255
  5. COMPRESS FOR OLTP NOLOGGING
  6. STORAGE (INITIAL 1 2 MINEXTENTS 1 MAXEXTENTS 2000)
  7. PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  8. USER_TABLES FLASH_CACHE, CELL_FLASH_CACHE DEFAULT DEFAULT)
  9. TABLESPACE 'XXXXXXXXX');

  Don't know what you mean... maybe this?
