• Local and Global Index confusion...

  Hi all

  Oracle Database 10 g Enterprise Edition Release 10.2.0.3.0 - 64 bit

  I have a partitioned table, when developing the application, they have committed an index ON this table. Previously, whenever we use to run 'Alter Table add partition..' global index becomes unusable and I used to rebuild the same. But in recent months, each time we add partition (Alter Table... ADD Partition..) on this table, index will get unusable to stat instead it shows that indexes THE data dictionaries (Lacality = Local in USER_PART_INDEXES). Partitioned indexes are also automatically created with each table partition creation.

  But the query below shows the output indexes are GLOBAL.

  Select double dbms_metadata.get_ddl('INDEX','ABCD','USER_A');

  Can someone me help on what actually happened here.

  But the example above has the keyword LOCAL?

  CREATING INDEX 'SEB '. "" CDRV_I1 ""SEBS ". "" CDRV ' ('CDRV_CURNT_FL', 'IND_LAST_VERSN', 'GMT_SEIZ_DT_TIME', 'CLECT_ZONE', 'CALL_ID',

• partation local and global index

  Hello
  
  I want partation tables in my database.
  Can someone tell me what exactly the difference between the local index & glabal.
  is there any link which can give me more informetion about the same.
  
  Thank you

  Local index is the index that is created on the partition key column name.

  Hi Anand

  Just to be clear, that a local index must not necessarily be created on partitioned key column, it is simply automatically partitioned in the same way as the underscore.

  If it contains effectively partitioned key columns is completely optional.

  See you soon

• Local partitioned Global Index Index conversion online.

  Hi all
  I use the Release of oracle 10.2.0.4.0 version. As a solution to solve a performance problem, I intend to convert one of the partitioned local index in overall index. Here is the script that I made, but it will take a time out as because other applications may use the same index and will suffer from performance during the transition problem. My question is if I can reach the same onlline, only because the prod database is too busy down time? Please suggest.
  
  Script:
  
  drop index INDX_c1c2;
  
  create the IDX_c1c2 index on tab1 (c1, c2);

  Your application will run without index during the time it takes to create. An alternative approach which avoids this would be:

  create index INDX_c1c2null on tab1(c1,c2,null);
  drop index INDX_c1c2;

  Always go read a CREATE INDEX of the Table.

  An INDEX REBUILD will be:

  (a) if the Index is in a VALID State-read of the Index online

  (b) if the Index is unusable-online read the Table

  You could make the Index UNUSABLE to force RECONSTRUCTION to read from the Table.

  I assume that you do NOT attempt a reconstruction in LINE and are ready to have the table locked for the duration of the reconstruction.

  But WHY YOU REBUILD the INDEX?  What is the reason?   Do you have proof that reconstruction will benefit?

• Volume D: is dirty. Check Disk Local Disk d does not solve the problem

  Whenever I start my computer under WindowsXP SP3, chkdsk runs indicating that the D: Volume is dirty.  He noted no other problems.  I tried to run check disk Local Disk d with two checked options, but it does not solve the probem.  What should I try next?

  That is right.

  First of all, let us look at the ideas of the Microsoft support engineer:

  I would never not follow the suggestion of Microsoft Engineer in method 1.  This idea makes no sense.

  The Microsoft Support Engineer method 2 does not work for you (or most people), unless you have a XP installation CD bootable authentic with the same Service Pack as your installation.  In your case, you would need a true bootable XP with SP3 installation CD and most of the people do not have such an animal.  It is therefore extremely unlikely that will help you at all - and if your file system is damaged or dirty, I of course never suggests that in the first place until your file system is straightened.

  Volumes that contain file system errors is known as "Sales". When a volume is dirty, he has known file system errors, and you must run chkdsk on the volume to repair the problem.

  When XP starts, it automatically checks the on each volume's dirty bit (C, D, E, etc.), and if any volume is dirty, XP will automatically run chkdsk/p on next reboot on the volumes in an attempt to clear the dirty bit.  Which does not clear the bit of impurity or it may take several passes.

  If the volume dirty bit, one is set, this indicates that the file system may be in an inconsistent state. The dirty bit can be set because the volume is online and has some remarkable changes, because changes have been made to the volume and the computer shutdown until the changes have been committed to disk, or because corruption has been detected on the volume. If the dirty bit is set when the computer restarts, chkdsk runs to verify the consistency of the volume.

  Whenever you start a computer that is running one of the Windows XP operating system or the Windows Server 2003 family, autochk.exe is called by the kernel for all volumes to check if the volume dirty bit is set. If the dirty bit is set, autochk performs an immediate chkdsk /f on that volume. Chkdsk /f verifies file system integrity and attempts to fix any problems with the volume.

  A simple power interruption is something that could result in a disc was marked as dirty.  Have you had a power failure these days?

  You can query the dirty bit on a volume from the command prompt window.  Here's how:

  Click Start, run and enter in the box:

  cmd

  Click OK to open the command prompt window.

  For example, to query the bit of impurity on drive D, type:

  fsutil dirty query D:

  The sample output:
  Volume D: is dirty
  Volume D: is not dirty

  Type "exit" to close the command prompt window.

  You can not enter any command to clear the dirty bit - only chkdsk /r or chkdsk/p can clear the dirty bit.

  When chkdsk runs automatically restart either because XP thinks he needs to (perhaps your NTFS volume has been marked as dirty) or you decide to schedule the chkdsk with error correction during the next reboot, the results appear in the viewing Application event log.  You should look there for the chkdsk log to see what happened and no problems after running chkdsk.

  To view the logs in Event Viewer, click Start, settings, Control Panel, administrative tools, event viewer.

  A shortcut to the event viewer is to click on start, run and enter in the box:

  %SystemRoot%\system32\eventvwr.msc

  Click OK to launch the event viewer.

  Search the Application log for an event originally by Winlogon, something like:

  Event type: Information
  Event source: Winlogon
  Event category: no
  Event ID: 1001
  Date: 04/08/2010
  Time: 11:25:57
  Description:
  Checking file system on C:

  The type of the file system is NTFS.

  One of your disks needs to be checked for consistency. You
  may cancel the disk check, but it is strongly recommended
  that you continue.

  Windows has finished checking your disk.
  Please wait while your computer restarts.

  The dirty bit fade not until chkdsk /r (or chkdsk/p) tracks clean when the system reboots (as in the example) or when you run chkdsk /r from the XP Recovery Console.

  Many times, the best remedy is to just run chkdsk /r from the XP Recovery Console so you can actually see what it does.  Sometimes, this also seems to be the only way to clear the dirty bit and this way you can see what he does.

  Note that you can not also question the bit of impurity of the Recovery Console and you can't turn off the bit of impurity to enter any command.

  If for some reason chkdsk will not erase the dirty, you can simply say XP never check the volume dirty bit, but who will not fix your fault of potentially hard drive, or it could be the drive just need to have chkdsk run on that (sometimes you need to run it more than once) or you will have to think about replacing the drive.

  If you have a genuine XP bootable installation CD, you can boot into XP from that (even a SP2) Recovery Console CD will work and run chkdsk /r manually from there and repeat until chkdsk /r is clean.

  If you have a genuine XP bootable installation CD, say so and I'll post instructions so you can make a CD of XP Recovery Console and how to run chkdsk from there.   There is no required XP media.

  I wonder why it is that I have never see an engineer Microsoft Support post instructions on how to make a bootable CD of XP (no XP media required) Recovery Console... probably because there is no KB article for them to post.

• conversion index global index local

  Hello guys, someone tell me how to convert a global index of a local index.
  The only method I know is to
  1 remove the global index
  2. create the index even with the local keyword.
  
  I was wondering is there any alter index statement which allows you to change the overall index to a local index?
  
  Thank you

• problem with the type of local and global

  Hi the gems...
  
  I have a plsql package. In the package, I defined a proc that takes two input parameters of type simple number and a parameter of a type of output collection.
  
  create or replace package pack_1 as body
  procedure proc_1 (p_number1 in number, p_number2 number, p_tt_table to tt_table) as
  v_tt_table tt_table:=tt_table();
  type c_ref_cursor is ref_cursor;
  v_c_ref_cursor c_ref_cursor;
  v_sql varchar2 (20000): = < a large sql using bind variables p_number1 and p_number2 >
  
  Start
  Open the v_c_ref_cursor for v_sql using p_number1, p_number2;
  loop
  extract the v_c_ref_cursor in v_tt_table;
  When the output v_tt_table.count = 0;
  for idx in 1.v_tt_table.count
  loop
  < business logic >
  end of loop
  end loop;
  close v_c_ref_cursor;
  < excpetion_block >;
  end;
  
  < several codes for the rest of the package >
  
  
  
  When I execute the proc_1 then he throws me error of data type incosistent while to fetch the v_c_ref_cursor of cursor in the v_tt_table variable.
  ORA-00932: inconsistent data types: expected - was -.
  But I have checked that the output of the query is similar with the type of variable.
  
  Now, a few facts: the tt_table of the user-defined table type is made from ot_table (create or replace tt_table to ot_table Board).
  The parent type i.e. ot_table has the same columns of this query in v_sql my proc.
  The ot_table and the tt_table are global types.
  
  But when I did these two types as local types, then the proc works very well. But I need them as global types only according to the condition in java.
  
  Please help me. The database is 11 GR 2.
  
  Thanks in advance.

  I'm trying to keep it in the simplest form... Please take a look...

  Ah... Easy to solve.

  The projection of SQL must be an object of type ot_test_type for extraction in bulk work.

  Your projection of SQL look like this:
  cursor c1 is select object_name from user_objects;

  object_name is a string - it is not of type ot_test_type.

  You must change the projection to return ot_test_type. This is done by using the default constructor for that type of object.

  For example
  cursor c1 is ot_test_type (object_name) select as the user_objects OBJECT;

  He may now be in bulk recovered in tt_test_type.

• Local/Global index for OLTP

  In our application (OLTP), we have a rule on
  
  * "" on all the partitioned tables, we need to have just partitioned LOCAL index "... *"
  I think that this rule is valid, because when we had GLOBAL index partitioned on the table when concurrent transactions
  was going on, we got below error:
  ORA - 00054:resource busy and...
  We get this error when rebuild us all indexes not valid...
  
  When we changed all the GLOBAL partitioned index at the LOCAL level... we get this error...
  
  We use MEV for cloud computing (i.e. we have several tenants and a partition for each tenant)
  
  
  My doubt is, is the rule as mentioned above may be still valid, because it is at odds with what is mentioned in the Oracle
  Documentation (the concepts guide)...
  http://docs.Oracle.com/CD/B19306_01/server.102/b14220/partconc.htm#i461446
  
  '' In general, you should use an index for OLTP applications and local storage of data or applications of DSS ''
  
  We use oracle 10 g 2...

  In our case, research www.lesormes.com will not create several partitions, only one partition (we have a partition for each tenant).

  Local is even better for you.

  Thanks for suggesting to rebuild online (for global)... I'll try with that... .but he would have any problem of performance relative to the index LOCAL...

  I don't think abnd so there shouldn't be any performance impact, rather it improves performance in locaking not all the table exclusively for the index creaiton.

  NY suggestion/idea why Oracle recommends partitioned Global index for OLTP?

  Because normally we have much aprtition of drop/merger/split partition of things in OLTP type (these operations are important in DSS normally loading data).

  any suggestion/idea why Oracle recommends partitioned Global index for OLTP?

  Because they are the fastest to access a record of a table and OLTP, response time is what counts. If you compare your reports OLTP or transactions, to spawn multiple partitions (a small percentage could access only a single partition and rules are made for the majority of cases, not for the small number of cases) and global index are better in this scenario.
  at MAS, you always have a huge data and as partition operation may stop your work until the index is rebuilt (which can take several hours for the huge data) where oracle is recommended to have a local indexing policy.

• Remote index not used with INSERT in the local table on dblink

  Hi all
  
  I don't know if anyone has come across this problem before, but for some reason any the remote index remains unused ONLY* in the insertion on the local database operation. Let me explain this pseudo-device code
  
  insert into LOCAL_TABLE
  Select / * + index_combine (alias_remote_tab IDX_LOG_DATE) * /.
  trunc (log_datetime),
  Count (*)
  of REMOTE_TABLE@DBLINK alias_remote_tab
  When trunc (log_datetime) = trunc(sysdate-1)
  Trunc Group (log_datetime);
  
  where:
  REMOTE_TABLE is a table partitioned on log_datetime (monthly)
  IDX_LOG_DATE is an index of bitmap of based on a valid function on log_datetime created in the trunc (log_datetime)
  local database: 10 gr 2
  remote database: 11 GR 1 material
  OS: windows (both)
  
  More funny thing is when I just run the select query independently on the only both local and remote, the index is used. I checked by printing the command explain for the select query plan. But when I prefix the query with the insert lose all hell breaks and local database plays the ignorance about the index. The command for the insert query explain plan has no mention of the index even when I explicitly place the index indicator in the select part of the query.
  
  If this should not be simple enough for ORACLE? Am I missing something here?

  Jonathan describes the details and the reasons for the behavior you see in following blog post http://jonathanlewis.wordpress.com/2008/12/05/distributed-dml/
  Your SELECTION is performed remotely (filtering and grouping) and sends only the (relatively) small results via dblink local database while the in an INSERTION, filtering only occurs at the remote and data site (relatively) important are sent via dblink to the local database, the consolidation takes place.
  You can give a try to the approach proposed by michaels2. If the approach from the view result grouping and filtering which will take place in the remote database, you will see improved performance.

  PS BTW, if the sql code that I suggested to check the plane, in my previous post using an index, then the cause of your performance issue is certainly not due to the index not used and is due to the amount of data transferred to dblink.

• Global variables are accessible from the local computer

  While he was trying to use RT project, I can deploy the file to the RT target and communicate with the host using a shared variable.

  But the host VI file returns an error stating that the shared in the pattern-block VI host variable is illegal.

  (RT.lvib\Link reqd\ 'shared variable' node is illegal)

  It also gives a description mentioning that global variables are accessible only to local machines.

  What is the cure?

  Hi Shan21,

  I think your problem with communication between the aim of RT and the host PC might be caused by how your deployment of your variables. Please take a look at the following and let me know what you think,

  Kind regards

  ******************************************************************************************************************************************

  When you make the executable of a project using shared variables, you must have a local copy of the variables on the deployment computer that are then linked to the 'real' shared variables stored on the target - cRIO, in this case.

  This means that the display of your project should look like this:

  

  Note: Two libraries, which can have variables with the same name because they aren't both on the local computer.

  The steps required are:

  1. create variables shared in the normal Manor on the cRIO:

  

  a. right click on the target
  b. new > Variable
  c. properties of the variables enter the name (stop); Data type (Boolean) and the Variable type (always in network-published).

  2. create variables shared on the host PC:
  a. follow the steps 1 a - c
  b. right click on the box to enable anti-aliasing

  

  c. linking to the URL of the PSP, click on Browse - and select variable on the target:

  

  d. click Ok.

  Note: Remember also to deploy the shared manually variable llb. See the related links for more information.

  Well not - enough is NOT that.

  The RELATIONAL indicator causes unnest Oracle object data and insert the data from the attribute itself rather than the object.
