• How it warns Oracle to use an index for the join of two tables...

  How to prevent the Oracle to use an index for the join of two tables to get a view online that is used in an update statement?
  
  O.K. I think I should explain what I mean:
  
  When you join two tables that have many entries sometimes there're better is not to use an index on the column that is used as a criterion to join.
  
  I have two tables: table A and table B.
  
  Table A has 4,000,000 entries and table B has 700,000 entries.
  
  I have a join of two tables with a numeric column as join criteria.
  
  There is an index on this column in A table.
  
  So I instead of
  

    where (A.col = B.col)

  I want to use
  

    where (A.col+0 = B.col)

  in order to avoid Oracle using the index.
  
  When I use the join in a select query, it works.
  
  But when I use the join as inline in an update statement I get the error ORA-01779.
  
  When I remove the '+ 0' the update statement works. (The column is unique in table B).
  
  Any ideas why this happens?
  
  Thank you very much in advance for any help.

  Hello
  I have a problem with the tabular form of Apex version 4.0.2.00.07.
  The page is divided into two parts: first a form with several field, completed by the procedure integrated apex, then a tabular presentation.
  The entire field of form displayed in mode 'View' only, one of them is P340_INIZIO_CONTRATTO, defined as a date in the database.
  
  In the form of tables, there is an attribute displayed as "Date Picker" and I want to give it the value of P340_INIZIO_CONTRATTO by default.
  
  If I simply put the name of the item in the field default value of this column, I get this error:

• Read the index for performance data

  Hello.
  Advice needed.
  I have the table as
  create table test (a varchar2 (20), ch. varchar2 (20), b varchar2 (20), d...)
  
  I have indexes for the column "a".
  Now when I'm data select 1st three columns (a, b, c) by 'a' of the criteria (select a, b, c fom test where a like '% aa') I'll have the execution of plan:
  
  1 scan interval Index
  2. access by rowid
  
  Now, I want to choose without 2nd operation. So I'm adding complex index for a, b, c.
  After that this select (select a, b, c fom test where a like '% aa') will read the index data.
  
  The question: is it possible to win some perfomance win this way? I mean, it is possible that the research by complex index (a, b, c) will take longer than the search by simple index (a) + access by rowid?
  

• Index for the Group of readonly cache table

  Hello
  
  Suppose I have a table in Oracle which is cached in TT as a readonly cache group.
  The oracle table has a primary key, based on columns (c1, c2, c3).
  
  Now, the oracle table also has a unique index (for example defined on columns c4, c5) in support of some queries.
  
  (1) is there a way to propagate this unique index for the cache group? (so that we can perform queries effectively TimesTen)
  
  (2) is it correct to assume that the group create cache statement MUST have the columns (c1, c2, c3) for the primary key? (that is, exactly the same as the pharmacokinetics of the oracle)
  
  
  Thank you!

  (1) after you have created the cache in TimesTen group, simply create the index needed on the tables of cache in TimesTen (using CREATE [UNIQUE] INDEX) as you would for any table.

  (2), it depends. A caching table must have a primary key defined in TimesTen. This PK must map to either a real PK defined in Oracle (same column names, order of the columns, data types, nullability, etc..) or a unique index defined on a set of columns not null (column names of the soul, order of the columns, types of data etc.).

• Unable to display data for the date where there is no entry in the table

  Hello

  Now, if I run the query:
  "select trunc (sale_date) sale_date, sum (sale_amt) total_sale of the sales group by order trunc (sale_date) by 1.
  It then displays the data for the dates there is an entry in this table. But it displays no data for the
  date in which there is no entry in this table.
  
  If you run the Table script with data in your schema, then u will see that there is no entry for the 28th. November 2009 in
  sales table. Now the above query displays data for the rest as his dates are in the table of the sale with the exception of 28. November 2009.
  But I need his presence in the result of the query with the value "sale_date' as '28. November 2009 "and that of"total_sale"as

• Delete the data in partitioned tables

  Hello

  Oracle 11.2.0.3.0 version, running on Linux Enterprise.

  I need to remove all the data from two tables (several 100 million lines each) that are partitioned.

  (1) table 1 is a partition table have varied to a DATE column

  (2) Table2 is a partition of reference table; partitioning is referenced on a relationship of foreign key to Table1 (column: key Table1.Primary)

  As I have no need for data, but want to keep the structure of the table, I would ideally like to delete partitions at the same time that the deletion of the data, so that the 2 tables partitioned and empty.

  Additionally, Table1 has some partitioned index I would be rebuilt as an index unpartitioned (given that Table1 will be empty).

  I thought I would start by removing all partitions of Table1 (via "ALTER TABLE DROP PARTITION nom_partition Table1"), but when the script came to the last partition, I got this error message:

  ORA-14083: cannot delete the only one partition of a partitioned table

  ORA-06512: at "SYS." DROP_PARTITIONS', line 46

  If someone could advise as to the best approach to what I want to achieve with regard to the two tables? Two tables down and recreate them then without partitions would be the easiest way?

  Thanks in advance for any guidance.

  If someone could advise as to the best approach to what I want to achieve with regard to the two tables? Two tables down and recreate them then without partitions would be the easiest way?

  Yes - delete the tables and re-create them.

  As says the exception that you cannot delete the last partition. A table is partitioned either or it is not.

  There was no interest at all to use DBMS_REDEFINITION to redefine tables because you do not want the data anyway.

• concatenate the data in 2 tables in a third table as well as in CONCATENATE strings

  Hello. as the title says, I wish to only concatenate the data in 2 tables in a similar third table that concatenate strings don't. All tables should be 1 d. For example, suppose that there is 1 table with the following: 1. 2; 3; 4 and table 2 with:; b; c; d. I would like a table 3 either 1 a, 2 b, 3 c, 4 d. Now this could be done easily with above mentioned concatenate strings, then table construction. but table 1 and 2 have something like 150 items. Rather painful. Any ideas?

  Hold arrays of two strings in a loop for example, concatentate the strings inside the loop and run the result réécrirait array3.

• ADF is intended for the data base designed with vertical diagram?

  Hello
  
  I want to know if ADF 11 g is intended for the data base designed with vertical scheme where even the names of columns will be stored in a generic table?
  
  Thanks in advance.
  
  Published by: user8925296 on April 12, 2010 10:06

  The short answer is no...

  What do you call a 'vertical plan', it's what others have called for a schema of entity-attribute-value or universal data model. I advise you to do some research open minded on these types of patterns if you develop an application before continuing. Great sound in practice, they have very inherent ease of use and scalability problems.

  If you have a superior taste of Windows 7 you can / must define the rights to change the time system and time zone via the policy editor gpedit.msc. They are defined in the strategy/Security Settings user rights assignments / Local. Ensure that only administrators and the Local Service can change these settings.

  If you have a taste less then you need to do it via a number of commands in the console, i.e.
  net localgroup
  NTRights users - r seSystemtimePrivilege-u
  NTRights u users - r seTimezonePrivilege

  You can download ntrights.exe here: http://www.microsoft.com/download/en/details.aspx?id=17657. If you choose this option, you may need to then more detailed instructions. Post again if this is the case.

• Storage VMotion - a general error occurred: could not wait for the data.  Error bad0007.

  People,

  I searched through this forum and have not found an answer that works in many positions out there, I say to myself that I would ask him once again.

  Here's the context:

  We have 12 identical Dell M600 blades in 2 chassis with 16 GB of Ram, 2 x Xeon E5430, they are all connected to an Equallogic PS 5000XV iSCSI SAN on a separate iSCSI (vswitch1) with 2 cards network dedicated network and dedicated switch, console svc iscsi dedicated, dedicated VMkernel port for iscsi access. Net access (vswitch0) contains port groups VM for our various networks and a console port and vmkernel svc for VMotion with 2 separate NETWORK cards as well.

  We are running ESX 3.5 U3 and VCenter 2.5 U3 on Win2k3 R2

  VMotion works between all servers, Storage Vmotion works for most machines, HA works and the value 2 host failurs with no monitoring of vm, DRS is set to manual for now I have a few machines on the local stores that I complete my rebuilt LUN, there is no set of rules for DRS and VMware EVC is enabled for guests of the Intel. However, I'll just describe one machine to do svmotion below.

  Here's the problem:

  I'm trying to Svmotion via svmotion.pl - interactive, a Machine to Windows 2000 with a virtual disk and a virtual RDM. I am aware of the requirements for the RDM and required parameters for svmotion, independent is not selected for the RDM, and I also have svmotioned several machines linux and win2k3 with the same configuration without problem. In the interactive session, I choose to individually place the disks and I chose the virtual disk to only the virtual machine to be moved, essentially, as I saw it move vdisk virtual machine and then copy to the pointer of the RDM.

  The use of the processor in this machine is about 25% average. but I try to run migrations at the time the lowest. and The Host it itself shows only about 5.5 GB of the 16 GB of RAM used. so I think we're good on the RAM. the volume/datastore that I'm migrating from has 485 GB free and the volume/datastore I migration towards a 145 GB free. the VM virtual disk is only about 33 GB.

  I run the script the windows version of the RCLI svmotion. and when to begin the process, I get the following error at around 2 percent of the progress:

  "Since the server has encountered an error: a general error occurred: could not wait for the data."  Error bad0007. Invalid parameter. »

  After searching around, I found the following hotfixes to the U2 release notes

  • Migrate.PageInTimeoutResetOnProgress: Set the value to 1.

  • Migrate.PageInProgress: The value 30, if you get an error even after the setting of the Migrate.PageInTimeoutResetOnProgress variable.

  I've made these changes, and I still get the same error.

  When I dig in the newspaper, I see these entries in the journal of vmkwarning:

  Any help would be greatly appreciated...

  Thanks in advance.

  The vmkernel on out of memory error, I had that before. And vmware support recommends setting 800M Max service console memory. And I did it and have no problems after that.

  See if that helps the issue.
