partion tables and indexes

• Partitioned Tables and indexes

  Hello
  
  
  I have a question on the table and index partitioning. My scenario is:
  
  Charge 2 mio records in table T once a month. Loaded records are added to existing records, and once loaded data is never changed.
  At some point, I want to delete the older recordings, so I intend to this partition table.
  
  T table looks like:
  

  create table t (id       number(10) not null  constraint t_pk primary key,
                  period   number(10) not null,
                  contract number(10) not null,
                  attr     number(10) not null);
  
  create unique index t_ux1 on t(contract,period);
  
  create index t_ix2 on t(period);

  My plan is to partition T over the period, and I'm trying to read through the concepts
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/partconc.htm#g471747
  
  
  My question is now, how to manage the indexes, the t_pk, the t_ux1 and the t_ix2. Concepts of say,
  
  «1. If the table partitioning column is a subset of index keys, use a local index.»
  
  "2. If the index is unique, use a global index. If this is the case, you are finished. »
  
  
  So, that's how I read it
  -t_pk is unique, so this should be global
  -t_ux1 of columns is a subset, unless I have misunderstood (?), which should be local
  -index t_ix2 column is the same as the partitioning column, so it must be local
  
  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?
  
  If true, what will happen when a partion fell?
  
  
  I am new in this area, so please feel the comment as you wish.

  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?

  A partitioned index locally can only be defined as unique if the partition key is part of the columns in the index. Imagine what the database would have to do if this is not the case: in order to verify if a newly added or updated value violates the uniqueness, it will have to travel all the partitions in a serialized operation - means that no one else could do the same thing at the same time. Since he is a killer of serious scalability in terms of locking and contention, this is not allowed.

  So: Your T_UX1 index can be defined as a unique index that is local because it contains the partition key. Although the index is not prefixed ("Prefix" means that it is divided by the left side of the columns in the index) which means that there may be access patterns where all partitions should be scanned or the optimizer cannot use a method of size of effective partition according to the way the index is reached.

  Your T_PK index cannot be set as local because it must be unique (you can not use a local non-unique index in this case), but does not contain your partition key. It must be a global index. An overall index can be partitioned as well (different from the underlying table) but it doesn't have to be.

  Depends on how you access your data you have not T_IX2 index when partitioning by this key because it corresponds to the partition key and therefore could not actually be used by the mechanism of partition pruning that limit your query to the scores of individuals.

  If you have more than one MAS environment where running queries are used longer, you should be fine with the index the in general (because they could be analyzed in parallel in parallel operations), but if you have an OLTP environment, then you should avoid local no prefix indexes due to the potential problem that you need to analyze all partitions.

  Be borne in mind that with partitioning adds an important layer of complexity to other areas: in particular the options available to the optimizer and analyze cost optimizer statistics. Depends on how you access your statistical data must be maintained on several levels now (level of score and at the global level, in the case of subpartitioning may be still at this level). If your data is important and you rely on "global" level statistics (these are always the case when the optimizer at the time analysis cannot limit access to a single partition) then in the pre - 11 g databases analyze these "global" level statistics can take a lot of time and resources, since actually , you need data several times (once for the partition and even global level).

  Presenting this partitioning may mean other potential problems in terms of execution that change (not for the better sometimes) plans and how to effectively collect statistics. Note that g 11 addresses the issue of 'statistics' by introducing the so-called "extra" global statistics. Greg Rahn wrote a [blog note | http://structureddata.org/2008/07/16/oracle-11g-incremental-global-statistics-on-partitioned-tables/] on this nice feature.

  >

  Since you're already on 10g, you can specify the database to update the scores of the local index using the UPDATE of the INDEX clause, while 9i could maintain only an overall index and it is up to you to rebuild the local index partitions after the partition DDL on the table (according to the DDL operation).

• New tables and indexes created do not appear in the view dba_segments

  Hi all
  
  I created 3 tables and indexes, but these items do not appear in dba_segments views. Is this a normal behavior? Previously, with dictionary managed tablespace, I can specify the least possible to create, at the table/index is created. But I don't know how works the locally managed tablespace. Please do advice. Thank you much in advance.
  
  I am using Oracle 11 g R2 (11.2.0.1.0) for Microsoft Windows (x 64), running on Windows 7.
  
  To reproduce this problem, I created the tablespaces as follows:

  An extension to what Sybrand said:

  There is a parameter called differed_segment_creation, who runs the behavior.

  If it is set to TRUE (the default), no segments will be allocated until you fill your table / index.

  Try to insert a row. You will see your table and index in dba_segments.

• How FLASHBACK all TABLEs and indexes in a certain pattern for a restoration of p?

  Today I read a few web pages on how to use FLASHBACK to restore to a Restore Point.
  
  Unfortunately, all of these examples show just how to restore a single TABLE for example
  
  FLASHBACK TABLE t to RESTORE POINT before_we_do_anything;
  
  But how can I FLASHBACK all TABLEs (and indexes and other dependent objects) in a certain pattern to a one-step restore point)?
  
  FLASHBACK myschema.* to before_we_do_anything POINT of RESTORATION;
  
  does not work.
  
  Peter

  There is nothing like that. However, you could flashback the entire database to a point in time. It would of course have implications through patterns all the good.

• After spending tables and index a different tablespace, index got unusable?

  Hello
  
  I moved to table and index a different tablespace. After the many indices obtained unusable. I did not understand thiis?
  
  How can I do still usable?
  
  best regards and thank you?

  If you bâtait the index (after moving the table, by the way), then they should be usable without something extra to see.
  Check this procedure only one (small) table and index if this index can be used later. If not, then you have a mystery :-)

• I'm looking for Custom table and index

  Hi Hussein;
  I want to find tables and indexes in the APPS schema. All custom tables and index begins with ZZ...
  
  I try to type this query, but its bring many record a lot, where I am not mistaken. And can not find the query for custom index.
  
  Select a.table_name, a.owner, d.CREATED
  from all_tables an inner join dba_objects d on
  a.OWNER = d.OWNER
  where table_name like '% ZZ' and 'a.OWNER =' APPS
  
  Thanks for the tips

  Hello

  You do not have to join, ask just DBA_OBJECTS (where type_objet = 'TABLE' and object_name like '% ZZ') or (where object_type = 'TABLE' and OWNER = "CUSTOM SCHEMA"). If you follow the standards of customization, custom tables/index should exist under the custom schema (and not under APPS schema).

  Kind regards

• The cache/pin layout tables and indexes - Howto?

  Hi all
  
  I touched upon a request by a seller of BEDS to do something I'm not terribly familiar with... they want to "hide" or "pin" a table and an index in memory.
  
  I was looking and saw something to the effect of making the Table1
  
  ALTER TABLE Table1 in CACHE;
  
  However, the seller has been mention some examples that seem to indicate the creation of a pool of Dungeon (a pool of buffers separate cache?).. and then doing something like
  
  ALTER TABLE Table1 STORAGE (USER_TABLES KEEP)
  
  Can someone give me an idea as to the difference between these two concepts... links on how do, etc.?
  
  Thanks in advance!
  
  Cayenne

  Hello

  There are 'rules' to pin the tables and indexes. The Oracle documentation states:

  "A good candidate for a segment in the pool of the DUNGEON is a segment that is smaller than 10% of the size of the DEFAULT buffer pool and has suffered at least 1% of the total i/o in the system."

  Here are the rules that I use:

  -Cache tables & indexes where the table is low)<50 blocks)="" and="" the="" table="" experiences="" frequent="" full-table="">

  -Cache objects that use more than 10% of the size of the data buffer.

  Here is the script I use to automate the assignment of the tables in the pool of DUNGEON.

  ATTENTION: This script is not for beginners:

• DBMS_STATS Table and Index Stats Question?

  All,
  
  Oracle database version: 10.2.0.3
  Operating system: Solaris 10 X 86-64
  
  We have a packed application we collect stats of objects with cascade = "TRUE". If the index statistics would be also collected in the process of collecting statistics. We do a estimate_percent = > 30 and method_opt = > all COLUMNS size AUTO no statistical calculation of these paintings that are huge (1 m lines - 192 m). The collected index statistics is based also on the estimate_percent product in the order.
  
  We found that some of the SQL had improved performance after the calculation of the index statistics in our Test environment that is a copy of production, updated daily.
  
  We thought the way to collect statistics:
  
  Collect statistics for tables with estimate_percent and Computing stats on index.
  
  We are making changes to our scripts and test approach in our Test environment.
  
  In the meantime, I would like to know the pros and cons of this approach?
  
  
  Thank you
  Anantha

  You run your own collect routine of stats, I understand that you disable an Oracle provides and plans automatically on 10g?

  What result did you get the Oracle supplied with AUTO_SAMPLE_SIZE routine?

  Estimate of the table and then calculating the index was something that I saw recommended in the past with ANALYZE and if you see the best results to the test, I think it would be worth in production.

  None of the environments applications two users are exactly the same, but the approach appears reasonable based on your observations.

  I suggest to bring together some before and after snapshots of query performance so that you have documentation of your results.

• INI_TRANS for TABLE and INDEX

  Hello
  
  My version of DB is 10.2.0.3
  
  As default, the INI_TRANS of the tables is 1 and for the index is 2. For some reason I have to increase the INI_TRANS of a table at 5, then what value set for INI_TRANS of indexes on the table?
  
  I read somewhere that INI_TRANS of the index to be set twice from INI_TRANS. means of the table if table INI_TRANS is 5 then INI_TRANS of the index must be set to 10. Is this true? If Yes, then what is the logic behind this?

  N °
  There is no useful guidelines for a generic parameter. Consider the conflicting scenes:

  (a) five sessions insert five rows separated in a single table block - with 5 locations of ITL. There is an index on the table, but the five inserted rows just keep these different values that their index entries go to 5 different leaf blocks: the index didn't need initrans 5.

  (b) using the different sessions to insert a row in a table - the nature of the SAMS means that (on average) there are 5 rows of SAMS 80 inserted into 16 different blocks - the SAMS table must be 5. However, in this case the indexed column is generated by a sequence and all 80 index entries should be inserted in the same block of sheets, so you initrans 80 on the index. (Except Oracle will make sheets index block split to work around the problems of initrans was too small on the concurrent inserts.)

  You need to consider the nature of the index and model of changing data for each unique index separately - and then you could assign initrans on the index to do NO MORE THAN the initrans + 1 table because (a) who will lose not too much space (b) he is not likely to let the too great claim to happen (c) Oracle will extend dynamically LAUGHED in most cases (d) if it is bad for an index special you will notice it pretty quickly - and there will be other problems (buffer waits occupied) deal anyway on this index.

• can we find unused tables and markings using OEM 12 c

  Hello
  
  I use OEM 12 c, databases are all about 11.2.0.3 and need to find if I can find many empty tables and markings unused acorss our env using OEM 12 c
  DBA create tables and indexes intended to test dummy and then they forget to delete these objects that are not been used for a long time.
  can I use a time regarding since when they are not being used and if they are empty using OEM 12 c.
  
  Thank you

  Don't know if EM can be used for this but you can use the audit to see if tables/indexes are used. See http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_4007.htm#i2116021

  Just to know if indexes are used, you can use ALTER INDEX USE of SURVEILLANCE;

• Creating a unique index frame on a one-to-many table and search

  I was properly put in place of the full text index on multiple columns on the same table (using the MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a table of one-to-many data collection (with a CF of a lookup table), and I need to get columns through two of these tables. Code example below, several of my chatter after the code block:

  I looked at DETAIL_DATASTORE and USER_DATASTORE, but examples of Oracle Docs for DETAIL_DATASTORE leave me a little confused. It seems that this should be fairly simple.
  
  Ideally, I try to avoid creating new columns and keeping a minimum shutter adjustments. But I'm open to any suggestion. Thanks for your time and your thoughts.

  I would create a procedure that creates a virtual with labels document, what is the multi_column_datatstore behind the scenes. Then I would like to use this procedure in a user_datastore, so the result is the same for several tables as a multi_column_datastore for a table. I would use auto_section_group or another type of Group of sections, so that you can search from WITHIN as with the multi_column_datastore. Please see the demo below.

• Table of contents and indexes appears in live Webhelp

  I work in a HR 10 draft updated from RH 9 project. During the generation of Webhelp, local output displays fine, but once compiled and download our online application, the table of contents and Index are not displayed - what I mean is that the tabs exist, you can click on them, but they are empty. Research works, as well as the header logo does not appear, although it is in the images folder that is downloaded.

  More details:

  • I view the project in an external file in the root folder of the project. To clarify, the project is in a folder named "Help", and the output is in a separate folder named '9.1 help' to the same level of the help file. When I provided the output, I only provide the folder «9.1 help» Could it be the cause of the problem?
  • After reviewing similar issues, I find that the HCC project file does not exist in my .hhk file, nor the .glo, exit, etc. I suspect that this could be the problem. However, insofar as I understand it, it is not possible for the final .htm file for the project in the same folder that contains these output files. You must publish in a different output outside the root path folder.
  • I tried to change the default table of contents and the Index under Webhelp settings > Categories > content of default in the table of contents specific to my project (this is the only table of contents and Index, so it shouldn't cause mistaked, but I don't know if this change means something).

  I would be happy to provide any other details if necessary.

  Thank you!

  Hello

  Just a parenthesis. The mark of the Web option will only apply when view you the contents of your local hard disk and that you use Microsoft Internet Explorer as browser. If you download this content to a server, the option may as well not exist. So it won't matter if it is enabled or not and would have no impact on this situation.

  Change the option of DHTML shouldn't really affect it either.

  @Colum - package_xx.html files are certainly part of the production of RoboHelp. After you generate WebHelp, you should see them in the whxdata folder.

  I think we've established that files display fine immediately after generating it, no? So, which suggests that the issue is entirely in the hands of perforce and that the development team. (or, more accurately, NOT to do)

  See you soon... Rick

• Easy to change the owner of the TABLE (and according to indexes and views) available?

  I want to change the Owver from a TABLE (and the owner of all VIEWS and INDEXES in function).
  The only way that I know so far is something like
  
  CREATE TABLE < newschema >. < table_name > select * from < oldschema >. < tablename >;
  
  Then, slide old TABLE
  Recreate it possible all the CLUES and the views.
  
  It is kind of bulky.
  Especially when I don't know what indexes exist for a certain TABLE.
  When I investigate this and I have found 4 indexes so much work needs to be done.
  
  Is there a shorter, smarter way to accomplish the task.
  I prefer a SINGLE task of all-for-statement
  
  :-)
  
  Thank you

• Check a functional index on a table and its metadata

  Hello
  
  I have a functional base normal index (unique) defined on a table that uses a function of decoding and a combination of the columns of a table.
  For example: decode (status, 'A', column1 | column 2, column1 | Column2 | Column3)
  
  Now my question is, how do we ask these functional indices of the database to see what exactly is the function...
  
  On the database when I run a query: -.
  
  Select in all_indexes where index-name =: index_name, *.
  
  She retrieves the name of the stored index code as ncs $00025 (don't remember the exact value).
  
  How will I know what exactly is the function? (from table)
  
  and is it possible that I can query the data that has been indexed by this unique index, so that I can check why unique constraint is violated in some cases?
  
  Thank you and best regards,
  Sylvain
