  correct syntax is
  ALTER TABLE.

  MOVE the LOB ()
  STORE AS (tablespace );

  Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

• Analyze tables after creating indexes

  Hi all
  
  I created new clues on the production environment, we must analyze tables after creating indexes. Why and what analysis do?
  
  Thanks for the help.

  There are so many different options and you'll certainly want to tweak your stats based on your system.
  The best thing to do is to read about dbms_stats:
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14211/stats.htm#PFGRF30102
  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14258/d_stats.htm#CIHEHDFB

  Here are a few examples to give you an idea of what they look like and how to perform:

  BEGIN
    DBMS_STATS.GATHER_TABLE_STATS(OWNNAME          => 'schema_name',
                                  TABNAME          => 'table_name',
                                  ESTIMATE_PERCENT => DBMS_STATS.AUTO_SAMPLE_SIZE, --> For really big tables oracle can just do a specific percent
                                  METHOD_OPT       => 'for all columns size 1', --> Defines Histograms, size one disables histograms
                                  DEGREE           => 12, --> The degree of parallelism so you'll see 12 parallel threads gathering stats
                                  CASCADE          => TRUE); --> gather stats on the table's indexes also
  END; 
  
  BEGIN
    DBMS_STATS.GATHER_INDEX_STATS(OWNNAME          => 'schema_name',
                                  INDNAME          => 'index_name',
                                  ESTIMATE_PERCENT => 50,
                                  DEGREE           => 4);
  END; 
  

  You can also do

  DBMS_STATS.gather_schema_stats
  DBMS_STATS.gather_database_stats

  and much more...

  I really want to focus on the need to do your homework on them,
  read the docs I linked and adjust your statistical parameters to fit your db objects and how they are accessed/used.
  Having accurate and meaningful statistics are very important to the performance of the database.

• Creating INDEX on a BLOB column in a separate tablespace

  Hello

  
  

  Our database contains 2 storage spaces :

  -Tablespace DATA : is reserved to hold the data.

  -Tablespace INDX: is reserved to hold the index.

  
  

  For some reason, that we must create the indexes on columns of type blob and the pending order are:

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT;  / / doc_content a blob type.

  SQL> index created
  

  Now, all indexes are created in the tablespace for DATA that is not good, they should be created in the tablespace INDX (now is empty)

  For this reason, and after a search, I specified the tablespace INDX , which will contain the index, and the used command is:
  

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT TABLESPACE INDX;

  *

  ERROR on line 1:

  ORA-29850: invalid option for creating domain index

  NB: also, when I try to use the same command with varchar column, it works.

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_name) TABLESPACE INDX;  / / doc_content a type VARCHAR2.

  SQL> index created

  
  

  Do you have an idea on how to create indexes on a blob column in a different tablespace?

  This question has nothing to do with the Oracle objects, but is related to Oracle Text, then perhaps that some moderator moves text objects.

  To specify a storage space for a ctxsys.context Oracle Text index domain index tables, you must create a storage preference, specify storage spaces in attributes of this preference, then use this preference in settings of creating index.  Please see the example below which shows first create domain index tables in the default users tablespace, then the creation of the field tables to be indexed in the example tablespace.

• How to create indexes of service according to

  Hi all

  I already post a thread associated with this thread, but there is little difference in the two threads.

  I had a query as below:

  Select concept_Un, raw_concept_a, relation_name, concept_b, discovered_relations raw_concept_b, where lower (concept_a) like '% of consumers' and lower (concept_a) like '% confidence % ';

  
  

  This query taking too long to run and its high rating.

  cost and execution time: 1155K and 03:51:11

  I changed above query using the Forum gurus, below query is changed:

  
  Select concept_Un, raw_concept_a, relation_name, concept_b, raw_concept_b

  of discovered_relations

  where regexp_instr (concept_Un, ' (consumer.*confidence) |) ((confidence.*Consumer))', 1, 1, 1, 'i') > 0;

  I created indexes for query modified as well:
  creating index SIDEV. IDX_reg_instr on SIDEV. DISCOVERED_RELATIONS (REGEXP_INSTR ("CONCEPT_A",'(consumer.*confidence) |)) (confidence.*Consumer))', 1, 1, 1, 'i'));

  After that the cost and time to get request reduces to:
  After optimization: 40001 and 08:01

  Now the question is whenever my request will vary as a condition, this means that search string can be vary to any value.

  So I need a basic index as function above is the index which can work for any string in the like operator, now my created index only works very well for the fixed string...

  Thank you

  Hi Chris,

  Thank you very much its working well, now, to reduce the cost and duration of execution, I used below queries as you suggest:

  create index idx_fulltext on discovered_relations (concept_a) indextype is ctxsys.context;

  Select * from discovered_relations

  where contains (concept_a, 'Confidence') > 0 and contains (concept_a, 'Consumer') > 0;

  Hello

  No, you didn't.

  The query I used was

  Select str

  of test_idx

  where

  contains (str, '% of the CONSUMPTION and CONFIDENCE %') > 0

  If you read carefully, you'll notice that I used already found lowercase uppercase searchwords.

  This works because the oracle text case insensitiv default you can read documentation:

  "By default, all text tokens are converted to uppercase and then indexed. This

  results in case-insensitive queries. For example, separate queries for each of

  the three words, CAT cat,

  "and Cat all return the same documents.

  If you have more to use tiny but need to start to read the oracle text docs ;-)

• Index rebuild after moving table to a different tablespace?

  Index rebuild after moving table to a different tablespace?

  Index rebuild after moving table to a different tablespace?

  Only if you want to reuse.

  See DBA guide

  http://docs.Oracle.com/CD/B28359_01/server.111/b28310/tables006.htm#i1106606

  Pass an array to a new Segment or a Tablespace

  Move a table changes the ROWID of the rows in the table. This causes the indexes on the table to be marked UNUSABLE , and DML, access the table using these clues you will receive an ORA-01502 error. The indexes on the table must be deleted or rebuilt. Similarly, all the statistics in the table become invalid and new statistics should be collected after the removal of the table.

• Create index partition in the partition table tablespace

  Hello
  
  I am running a work custom that
  
  * Creates a tablespace by day
  * Creates the daily table partition in the created tablespace
  * Removes the days tablepartition X
  * Removes the storage space for this partition of X + 1 day.
  
  The work above works perfectly, but it has problems with the management of the index for these partitioned tables. In the old database (10g - single node), all indexes and partitions exist in a BIG tablespace and when I imported the table creation script in the new database, I changed all the partitions table & index to go in their respective space.
  
  For example:
  
  Table_name... Nom_partition... Index_Part_name... Tablespace_name
  ============...================............====================...........=================
  TABL1... TABL1_2012_07_16... TABL1_IDX_2012_07_16... TBS_2012_07_16
  TABL1... TABL1_2012_07_15... TABL1_IDX_2012_07_15... TBS_2012_07_15
  
  
  But now, when the job is run, it creates the index in the tablespace TBS_DATA default.
  
  Table_name... Nom_partition... Index_Part_name... Tablespace_name
  ============...================.............====================...........=================
  TABL1... TABL1_2012_08_16... TABL1_IDX_2012_08_16... TBS_DATA
  TABL1... TABL1_2012_08_15... TABL1_IDX_2012_08_15... TBS_DATA
  
  
  I can issue alter index rebuild to move the index to its tablespace default, but how can I make sure that the index is created in the designated tablespace?
  
  NOTE: the partition/tablespace management work that I run only creates the partition of the table and not the index.
  
  
  The new env is a cluster of CARS of 2 nodes 11 GR 2 on Linux x86_64.
  
  
  Thanks in advance,
  aBBy.

  try something like this

  ALTER table tab_owner.tab_name add the partition v_new_part_nm
  values less (to_date('''|| v_new_part_dt_formatted ||'') ((', "DD-MON-YYYY)) tablespace ' | part_tbs

• Events of waiting "log file parallel write" / "log file sync", in CREATE INDEX

  Hello guys,.
  my current project I'm running a few tests of performance for oracle data guard. The question is "How LGWR SYNC transfer influence the performance of the system?"
  For the performance of the values, that I can compare I just built a normal oracle database in the first step.
  
  Now I perform various tests such as creating index 'broad', massive parallel inserts/validations, etc to get the marks.
  
  My database is an oracle 10.2.0.4 with multiplexed on AIX log files.
  
  I create an index on a table of "normal"... I have run "dbms_workload_repository.create_snapshot ()" before and after the CREATE INDEX for an equivalent period for the AWR report.
  Once the index is built (round about 9 GB), I made an awrrpt.sql for the AWR report.
  
  And now take a look at these values of the AWR

                                                                     Avg
                                               %Time  Total Wait    wait     Waits
  Event                                 Waits  -outs    Time (s)    (ms)      /txn
  ---------------------------- -------------- ------ ----------- ------- ---------
  ......
  ......
  log file parallel write              10,019     .0         132      13      33.5
  log file sync                           293     .7           4      15       1.0
  ......
  ......

  How can it be possible?
  
  With regard to the documentation
  
  -> synchronization of log file: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120

  Wait Time: The wait time includes the writing of the log buffer and the post.

  -> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104

  Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.

  This was also my understanding... "log file sync" wait time should be higher than the 'parallel log writing' timeout, because of, it includes the e/s and the response time for the user's session.
  I could accept it, if the values are near each other (perhaps around 1 second about altogether)... but the difference between 132 and 4 seconds is too visible.
  
  Is the behavior of the log file sync/write different when you do a DOF as CREATE INDEX (maybe async... like you can influence it with COMMIT_WRITE initialization parameter?)?
  You have no idea how these values born?
  
  
  Ideas/thoughts are welcome.
  
  Thanks and greetings

  Boredom comes with the IF statement. I get the following error message:

  And there is nothing in V$ SESSION leader/block/line current. class obj # is EMP. current sql_id is the CREATE INDEX.

  If anyone has an idea on:

  -Why creating an index in line must wait for transactions that modified only parent table

  -How to continue the investigation

  -can or cannot reproduce in other versions

  Thanks in advance,

  Franck.

  I guess you have a constraint foreign key between emp and Dept.

  It's expected behaviours: since 11.1 any DML at one end of a referential integrity constraint translates into a mode lock 3 taken at the other end, and your phenomenon resembles a side effect of this.

  When you try to create the index online that your session must assume that the other session (holding mode 3 on the emp and dept) may have changed the emp and dept, so it must wait for the session to the commit or rollback.

  (I guess that in principle, he could walk the cancellation of the transaction see if EMP had in fact been changed - but maybe who was considered too complicated to be worth the risk to implement)

  Updated - I just did a quick check to reproduce the effect on 11.1.0.7

  For reference - here are a few notes on modes of locking and how the application has changed over time: https://jonathanlewis.wordpress.com/2010/06/21/locks/
