Rebuild all indexes of a table

y at - it a single command that would rebuild all indexes of a table?

No, but you can use

select 'ALTER INDEX '||INDEX_NAME||' REBUILD' from user_indexes
where table_name=
And you can run this query.

Re-create all indexes on new data files
 
			 
Hello
on FSCN 9.2 on Win 2008
We'll re-create all indexes (belonging to sysadm) in the new data files.
-Are there any script or utility to do this?
-can you offer me any scenario?
Otherwise, I think only of:
0-extract DDL for all areas of storage and index.
1-drop tablesapces
2 Create tablespaces (by the DBMS_GETDLL script ('TABLESPACE'...)
3 re-create all indexes (by the DBMS_GETDLL script ('INDEX',...))
4 rebuild all indexes.
Any idea?
Thank you.

There is no trace of PeopleTools that stores the name of the tablespace for the index.
Here's how to work the tablespaces.
There is a table called PSDDLMODEL where we store the information of DOF model for index and table creation, among other things. DDL models contain a template with replaceable parameters. One of the parameters in the create index Oracle is a field called INDEXSPC. This field by default is PSINDEX.
If you wish to override this value, you can go in the App Designer, open a folder, select Tools-> data Administrations-> select Index to edit the index and then select modify DDL, then select change the setting for the Create Index and Create Unique Index model. This replaces PSINDEX for this record. The name of the underlying table is PSIDXDDLPARM.
If you want to change the default PSINDEX to something else, go to the utilities Menu and use DOF model by default and change the PSINDEX to something else. Once you change this setting, the next time that you create the index, it will be created in the tablespace.
If you create an index in a different tablespace outside PeopleSoft, we have no knowledge of this and do not update our tables in order to take into account where he currently resides. Once you have updated the default template and replaced the records you want to replace, you can make a Data Mover, followed of a Data Mover import export and the index will be created as they have been redefined. Or you can just do a SQL Create Index and re-create all of them.
		   
 
            
           
 
		     
Index rebuild required after truncate the table and load data
 
			 Hello




I have a situation that we truncate tables bit and then we loaded data [only content] on these tables. What you need to rebuild the index online is necessary or not?




And another question is if we drop a few clues is the total amount of space is released or not. And re-create indexes will use the same amount of space. As I don't have disk space more? In this situation, rebuild the index online will be a better idea...


Can you please on this...




truncate the table some the few loading tables + reconstruction markings online is the best (or) droping little tables, a few tables loading + re-create the index is better


Can you suggest the best way... We have a time that it currently we don't have enough space on the disk... [Option should not effect the space]			 
user13095767 wrote:
Ok. I have it...

If the indexes are enabled, then rebuild again is not necessary after loading tables...
Please answer if my understanding is correct...
above is correct

If so, how abt the differences in the space occupied by the spaces of storage during the index rebuild and re-create... T he acquires more space if recreate us [deletion and creation] or rebuild online is preferable to an index...?
space used is the same for all options.

Shrink the table, rebuild the index?
 
			 I need to reduce some very large tables after the removal of lines and I want to validate the script to run. I was thinking something like this:
run_deleting_process;
change the movement line of table my_tableI enable;
ALTER table my_table retractable space WATERFALL;
change the movement line of table my_tableI disable;
I need to rebuild the index after that?, or if I rebuild the markings, can I delete clause CASCADE of the command? It is recommended to run utltrp.sql after shrink the table?, maybe some dependent object needs to be recompiled after the reduction of a table?
The database version is 11.1.0.7 and documentation does not specify that the index rebuild is required, but I realized it is a desition normall when the narrowing of the tables.
Thank you			 
No there is no rebuild the index after shrinkage. And if you use "cascade", your index will be supported. You do very well.

rebuild the index partition
 
			 Hello
I have unusable a clue. Now I want to rebuild the index for this I have to rebuild the partition and the tablespace in two different command as


Index_name ALTER INDEX REBUILD PARTITION p1;
Index_name ALTER INDEX REBUILD PARTITION p1 TABLESPACE INDX_TS;
now my question is when I run first command and check the index of fof status it shows not usable. In the same way when I ran only 2nd order also rebuild successfully. If I ran only 2nd command works fine?
why it displays usable after only rebuild partition?




I have script for all indexes on user like this


Select 'ALTER INDEX' | index_name |' rebuild partition '. Nom_partition | ';' in USER_IND_PARTITIONS
Select 'ALTER INDEX' | index_name |' rebuild partition '. NOM_PARTITION | 'SPACE '. nom_tablespace | ';' in USER_IND_PARTITIONS			 
Why you set all the indexes to be UNUSABLE?
(Please don't keep saying "unuse index", do you mean "occupies an unusable index"!)
The instance / session SKIP_UNUSABLE_INDEXES setting determines the behavior of DML. In 9i, it is false by default. In 10g, it is by default true. Thus, in the 10g (unless you have changed it back to FALSE), INSERT/DELETE operations can succeed even if an Index is UNUSABLE. However, indexes to enforce PRIMARY KEY constraints or unique indexes (index created in CREATE a UNIQUE or apply INDEX of UNIQUE constraints) cannot be ignored by normal DML.
(Direct path operations automatically update the index and, therefore, can leave clues in an unusable state temporary.) These look like actually to DDL operations and lock the partition table/preventing simultaneous updates).
		   
 
            
           
 
		     
Rebuild the indexes in Win Explorer: old folder back.
 
			 
I rebuild my index every month. When I do, I get an old folder in the My Documents folder. It appears once I do the reconstruction.
Here's what I do:
Control-> system and Maintenance-> Indexing Options Control Panel
Click on the Advanced button
Re-index selected location: click the Refresh button
Places that have always been selected for reconstruction are:
OneNote
IE
Start menu
Users
The old folder that keeps appearing once completed the reconstruction process is not among the users of--> username--> Documents folder under the location list.
It is not a big problem for me to remove this old issue of each month. But I would like to know what is happening here in case there is something wrong with my system.
			 
I discovered what was going on. I hope it's useful to someone.

    

I use a software CoffeeCup HTML editor. In the window of the preferences of this application, I had the path to the 'default Web site project folder"pointing to the folder that kept reappearing. When I changed the path to an existing folder, I got is no longer this mysterious folder reappears.

    

It is logical. The application was create the folder whenever I opened it because he needed new projects.
I also tested this theory by creating a new default folder, delete and then opening the application. He kept creating the folder.

    

A big "thank you" to all of you who have looked at this and I tried to understand.

Once the sentence you say ' does not ' and then you go to paste plans that seem to show that it "works".
What gives?
In fact, if you look at the plans - think Oracle you have 16 k rows in the table and he'll be back k 12 rows for your select statement. In this case, Oracle is picking up the right plan - full scan 16 ranks of k is a lot less work to digitize the index lines k 12 followed by the research of rank k 12 rowid.
		   
 
            
           
 
		     
CTXCAT index on partitioned tables
 
			 
Hi all
I use an oracle 11.2 database and try to use the index for a sample application oracle CTXCAT.
I saw that oracle reference documentation "the CTXCAT index can't stand table and index partitioning, not...» "in http://docs.oracle.com/cd/B28359_01/text.111/b28303/ind.htm#BEIIEAFD
But I was able to create a CTXCAT index on a partitioned table query to use it successfully.
So can someone tell me exactly it meaning in the documentation of oracle developer "CTXCAT index does not support index and table partitioning?
Thanks in advance,
Mor.
			 
This simply means that you cannot create a LOCAL partitioned index on a table partitioned using the CTXCAT indextype. There is not probably the creation of a global index (ie. covering all partitions) on a partitioned table.
The wording could be clearer.
		   
 
            
           
 
		     
reconstruction of indexes on a table with version
 
			 
Hello
I'm under oracle 11.1.0.7 on Windows.
I would like to rebuild some clues that have gotten big enough and also move to a different tablespace (the tablespace in a also increased big enough). I'm new on the Workspace Manager and when I tried to do the 'alter index... rebuild' command has encountered an error. I was told that I could use this package:
AlterVersionedTable
Modifies a table compatible version to add valid time support, rename a constraint or rename an index.
Syntax
DBMS_WM. () AlterVersionedTable
table_name IN VARCHAR2,
alter_option IN VARCHAR2,
parameter_options IN VARCHAR2 DEFAULT NULL,
ignore_last_error IN BOOLEAN DEFAULT FALSE);
Parameters
Table 4-5 procedure AlterVersionedTable parameters
Parameter
Description
table_name
Invalid name of the compatible version table to add support for time. The name is not case sensitive.
alter_option
One of the following values: ADD_VALID_TIME to add valid time support DDL to make changes DDL, RENAME_CONSTRAINT to rename a constraint, REBUILD_INDEX to rebuild an index, RENAME_INDEX to rename an index, or both USE_SCALAR_TYPES_FOR_VALIDTIME  or USE_WM_PERIOD_FOR_VALIDTIME to specify if the views on a table compatible existing version must use two scalar columns for the valid time interval.
See the Usage Notes for more information on these options, including when you need and can use this procedure to rename an index or a constraint.
parameter_options
A quoted string (in the general format ' keyword = value keyword2 = value2,...) ") containing the valid keywords for the specified alter_option value of the parameter." See notes on the use of the keywords that are valid for each alter_option value to the parameter.
ignore_last_error
Boolean value ( TRUE )  or FALSE ).
TRUEdoes not realize the last error, if any, that occurred during the previous call to the BeginBulkLoading procedure. Information about the last error is stored in the USER_WM_VT_ERRORS and ALL_WM_VT_ERRORS of the data static dictionary views, which are described in Chapter 5. See usage for more information Notes.
FALSE(by default) don't ignore the last error, if any, that occurred during the previous call to the procedure of AlterVersionedTable.
I install a simple test case:
DBMS_WM EXEC. AlterVersionedTable('PASIKOWN.) NP_ROAD_PIECE ',' REBUILD_INDEX ',' index_owner is pasikown, index_name = np_road_piece_pk, tablespace = quest_128k "(, NULL);"
and it seemed to run ok. Stamped it 'last ddl' on the change of index so I guess that he rebuilt the index (my test cases was very small, so I see no difference in the number of extensions. However, he did not the indexes in the tablespace that I listed.
Is it still possible?
My humble thanks
Nicole
			 
Hi Nicole,.
When you use the dbms_wm REBUILD_INDEX. The AlterVersionedTable procedure, the only supported parameters are index_owner and index_name.  That's why specifying that storage space makes no difference.  To move an index that is not a primary key in a different tablespace, you do not want to use dbms_wm.beginDDL and dbms_wm.commitDDL and cause a 'alter index... rebuild "command on the table of the skeleton.
For example,.
SQL > exec dbms_wm.beginDDL('PASIKOWN.) NP_ROAD_PIECE');
SQL > alter index rebuild tablespace pasikown.np_road_piece_pk quest_128k;
SQL > exec dbms_wm.commitDDL('PASIKOWN.) NP_ROAD_PIECE');
However, according to the name of the index you specified, I guess that's the primary key.  We do not support the amendments of the primary key index once it was created during the EnableVersioning by beginDDl/commitDDL.  Therefore, you must use the option of dbms_wm DDL. AlterVersionedTable and use the following as a parameter of the ddl: 'ddl = "alter index rebuild tablespace quest_128k pasikown.np_road_piece_pk" '.  See the documentation for details on this option.
Kind regards

How to fix this?
(a) run several parallel create sqlplus statement index different sessions
(b) create a tablespace to put data files in different hard drives like D: E: F: C:
(c) create the separate tablespace for each hard drive and map it to a single disk IO benefit
(d) I have 8 processors but parallel 32 is not speed
(e) how these clues I can run in parallel. Is it OK to run 20 parallel index 32 sqlplus sessions
All that I have to create 20 index on the table of 500 GB
target memory = 30GB
index of names to create 20, each index is 10 GB
his is of 80 hours (4 hours per index)
This machine is waiting, I just used all the resources of the machine to accelerate.
Thanks for reading this
Thanks for the help in advance

Sorry, I misread it: this question was not from you. My apologies. My solution should work for you, however: give yourself a big PGA, manually. Automatic PGA management using not will never give you enough.
		   
 
            
           
 
		     
Remove all InDex markers in empty cells
 
			 
I have a doc with a lot of tables with empty cells. Each empty cells have a markers to index in it and I need to delete all the.
The replacement of find/replace ' ^ I ' of "(Nothing) do not remove.
Is their a way to remove all Index markers via a script?

Can you send an example idml or inx?
If not maybe you can try something like this:
var aDoc = app.documents[0];
var allTables = aDoc.stories.everyItem().tables.everyItem().getElements(); 

app.findTextPreferences = app.changeTextPreferences = null; 

app.findTextPreferences.findWhat = "";
app.changeTextPreferences.changeTo = "";
aDoc.stories.everyItem().tables.everyItem().changeText();
app.findTextPreferences = app.changeTextPreferences = null;
alert("done");

It is a part of a screenplay written by Uwe Laubender. I think this could help you.
		   
 
            
           
 
		     
Request from oracle to MySql using dblink read all rows in the table
 
			 Hello
I use the heterogeneous connectivity between oracle 10204 to the Mysql database.
I have a database of link on the side of the oracle.
I request a table in MySql with 10 million rows.


His is not serious if I am running:
' Select * from ' CDR_Accounts"@mysql where 'id '= 7675405;
or
Select * from 'CDR_Accounts"@mysql;


There is an index on the column id.
It seems that the Mysql is feteching all rows in the table, all data is transferred to oracle on the dblink and only after the required lines are back to the client.


The /etc/odbcinst.ini file is as follows:


[odbcprd:oracle@odbc /software/oracle]$ cat /etc/odbcinst.ini
[myodbc3]
Description             = Mysql connector to mysql version 3.5
Driver          = /software/oracle/MysqlOdbc/3.52/lib/libmyodbc3-3.51.25.so
Driver64                = /usr/lib
Setup           = /software/oracle/MysqlOdbc/3.52/lib/libmyodbc3S-3.51.25.so
Setup64         = /usr/lib
UsageCount              = 1
CPTimeout               = 3600
CPReuse         = 
Please advice
