• Creating graph xy table of index

  Hello

  I am creating a chart xy of two files of different path. Each file path has a reading of the spreadsheet attached to a table of index to enter a specific column of each file. I want to use the column of each file to x and y values of the axis. But I can't get the graphics to show anything when it is connected to the array index. I tried to use the bundle but it did not work. Any suggestions?

  
  

• Clear on how the table of Index OpenG works with a 2D Arrray

  Hello

  I don't understand how to use the undex OpenG table with a table entry 2D. I joined the contest help window, said that aid

  "For 2D tables, connect the clues and indices 0 1 entries to specify the items you want.

  So what does really mean? I wired the vi as requested and the vi always puts a 1 d table. So are the lines of entries in table two indexes and columns or what?

  I am sure that you send in your line indices table and the table of the column indices and get out of your table 1 d of elements.

  (i.e. rank table [1,5,7] and table column [4,8,10] gives you a table 1 d elements (1,4), (5.8), (7.10))

• partion tables and indexes

  Hi all
  
  DB: 10.2.0.4
  
  Is that we can convert a normal table into partitioned tables?
  If Yes, then what is the existing indexes on this table?
  
  IM totally new about partitioning (Table and Index). I read the oracle docs but still have confusion with local and global index (score and no-partion)...
  
  
  Please suggest...
  
  Kind regards.

  You can use the EXCHANGE PARTITION to do. See this article from the Oracle base
  Partitioning of an existing Table using the EXCHANGE PARTITION
  http://www.Oracle-base.com/articles/Misc/partitioning-an-existing-table-using-Exchange-partition.php

  Or you can use for DBMS_REDEFINITION do directly

  See this article from the Oracle base
  http://www.Oracle-base.com/articles/Misc/partitioning-an-existing-table.php

  You can also create a new table and INSERT the data from the old table.

  The option you are using could depend on indexes how you have, if you intend to keep them all and if the indexes on the partitioned table must be either local or global.

  To refine the new partitioned table, you really need evaluate each index to determine that the index should be global or local, and if the index should also be partitioned.

  There isn't any point to create a new table with the same indexes if you want to redefine all the indexes. You would be better of the backup of the original and then table drop indexes before conversion.

• 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.

  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 to specify a table in Index?

  I've looked everywhere, I can think of for this: How can I specify a particular table in a table in Index?
  
  I found the statement "You can choose many options of creating table and table organizations (such as the partitioned tables, organized in tables and external tables index) meet the diverse needs of a company." in the SQL Developer Data Modeler 3.0 Users Guide, but not other references such as the way to achieve this.
  
  Thank you
  Mike

  You must open "Relational model", then "models". After choosing an Oracle implementation. Once this done, under "Tables", you will find your table in the physical model. Double-click the table that you want to make an IOT. On the "General" tab in the menu drop-down 'Organization' you can choose: "INDEX". 'Apply' ing and / or keys 'Ok' from the main menu, 'See'--> 'File DDL Editor_'--> 'Generate'--> 'Ok', you will see your table took the DDL generated for an IOT.

• 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.

  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:

• 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.

  >

  If true, what will happen when a partion fell?

  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).

• Table of index always returns zero when reading the table 3D

  I have a 9 x 2000 x 5 table table 3D diamension.  I have this table filled with data and when I try to read a data point unique on the table the function Index Array always reads zero. I place a probe on the 3D input array and when I put in the index of the probe to the same data point the probe shows the value stored in the table. I also have an indicator showing the 3D table and it displays data in all locations. For example if I try to read the location 0, 144.0 in 3D it array always return zero. Yet I know that the value of this element is 6.8616E - 5. Each item I try to retreave table gives zero.

  Anyone saw the Index room table this kind of behavior?

  Problem solved. As usual, it was pilot error on my part had knocked down the lines of lines and columns.
