IOT tablespace

Hi All,
Is it recommneded to put IOT (index organized tables in index tablespace or data tablespace?
Is it possible to move just the index of the IOT in different tablespace?
I am using Oralce 11g.
Many Thanks.

If you're using separate tablespaces for data and indexes, then I suggest putting the table iteslf (and therefore, the primary index) in the data tabelspace. If you have any additional indexes, put them in the index tablespace.
Note that, depending on how your disks are configured, there may not be any advantage to having separate tablespaces for data and indexes.
For example, one of my databases has data files on the G, H and I drives, but those 3 drives are really just logical partitions of the same Raid array, and I/O on the G drive is just as likely to contend with I/O on the the H and I drives as it is to contend with other I/O on the G drive.

IOTs and overflow tablespace

Hi everyone,
I created an IOT without an overflow tablespace. What does Oracle do if it cannot fit a row into the index block? Do it give an error or will it use multiple index blocks to store the row of data?
Thanks,
Paul

<quote>I created an IOT without an overflow tablespace.

It will never happen.
An IOT defined with or without an overflow will get a default PCTTHRESHOLD of 50 ...
the allowed values are between 1 and 50.
PCTTHRESHOLD represents the percentage in an index block which could be occupied by one IOT row.

So, Oracle sees we didnt define an overflow and does some upfront checking on the declared size of the row
(BTW, it will be the same if the CHAR columns were defined as VARCHAR2).
It figures up it cannot store a row in 50% of my 8K block (there is some overhead in the block too).

Not it can. And just to show, PCTHRESHOLD is defaulted to 50

So, if you have wide rows you better have an overflow well, you have to.

One user for multiple tablespaces

Hello.
Oracle 11g enterprise.
Whenever I setup a new tablespace on my server, I create a user for each tablespace on the server.
Is is possible to create only one user for all tablespaces on a server?
What is the easiest way to create this one user to have all roles and privileges across all tablespaces?
Any suggestions are greatly appreciated.

I would seriously question a design with 'N' databases (whether they are on 1 or more or 'N' servers is not the issue) and DBLink from each of the databases to every other database.
Not only is it going to be hell to manage (how and when can you decide to shutdown a database for maintenance / patching / server/hardware maintenance when you have N-1 others connecting to it online), but it indicates a possibly high level of data duplication.
So we still revert to why you think you need that many databases and that many users and that many database links.
As has been pointed out, there is no relation between tablespaces and DBLinks. NONE whatsoever.
As for tablespaces and users, I can have
a. One Tablespace and 10 database accounts with any 1 to 10 of the accounts storing data objects in the tablespace
b. Ten Tablespaces and 1 database account storing data objects across all 10 tablespaces
c. 100 database accounts but only 1 to N of them having any data objects, the others only doing SELECT/INSERT/UPDATE/DELETE on objects owned by 1 to N schemas. (This one schemas all being in 1 tablespace or M tablespaces).
There is no one-to-one correspondence between users and tablespaces necessary. Tablespaces are for logical grouping of data objects.
I keep referring to data objects as these (Tables, Indexes, LOBs, IOTs, Clusters etc) require storage. Objects like Sequences do not require separate tablepaces although they have persistent values. Objects like DBLinks and Views are only definitions and require no storage (other than in the data dictionary !). Objects like Procedures and Packages and Triggers are code objects and require no storage (other than in the data dictionary).
So :
1. Such a design needs to be questioned.
2. Even if you need such a design, do not tie DBLinks to Tablespaces.
3. Even if you need DBLinks, do not tie Users to Tablespaces.

TEMP tablespace getting full while inserting a CLOB in Trigger

We have a Oracle 10g (10.2.0.4.0) DB on a Solaris 9 box which also runs our J2EE web-service application on Weblogic 8sp6 server.
We get around 220K web-service requests from upstream callers daily to insert data in the main table, say TABLE1, which has daily partitions on a date column. This table has around 21 columns out of which 1 is a CLOB column.
Now this table has an AFTER INSERT trigger which calls a package procedure to insert the same record into another table, say TABLE2.
From Java application insert statement in executed in below format using a weblogic jdbc connection pool :
INSERT INTO TABLE1(COLUMN1, COLUMN2, ........., CLOB_COLUMN,........, COLUMN21) VALUES (:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15, :16, :17, :18, :19, :20);
Clob object is prepared in application using ojdbc14.jar.
We are observing a strange issue here. The TEMP tablespace utilization keeps on growing as more and more inserts are executed by application and after ~125K inserts the TEMP tablespace gets full and we start getting ORA-01652 error.
On further analysis we could see that there are only 7-10 session being maintained but as more and more inserts happen TEMP tablespace utilization goes on increasing for each of these sessions.
When we tried with inserting just few records and then watching the session details in v$session_wait then we could see that it is in INACTIVE state and waiting for the event ‘SQL*Net message from client’. This does not seem correct as the session has successfully inserted the data and committed the transaction and we can see the data in the tables as well.
The confusing thing here is when we modify the trigger to pass blank string('' ) instead of the CLOB column to TABLE2 then this issue does not occur. All 200K records are inserted properly and TEMP tablespace utilization also keep always below 1%.
Can you please help us in solving this issue. Is this related to any oracle issue?
Inside the package we have tried using DBMS_COPY statement to copy the CLOB column after insert but still same result.

My first thought on reading your post is that not only are you using a database version that is now so old it is in extended support and even then not even the most recent patchset for it.
The first thing I would do is move to 11gR2 and if you can't do that at least get to 10.2.0.5 and apply CLOB relevant patches as well.
Same goes for your operating system. Solaris 9 is ancient: So move to 10 which has vastly improved memory management.
To help you further it would be really valuable to know the table layout. For example is this a heap table or an IOT? Is it partitioned? Is this RAC? What size are the CLOBs? Are they stored in-line? Chunk size? etc.
This page should start you down the right road:
http://docs.oracle.com/cd/B19306_01/appdev.102/b14249/adlob_tables.htm#sthref204
But I am also wondering why you would use a trigger to, as you say, "insert the same record into another table." This description is a poster child for "bad design."

Partitioned IOT of Object Type - mapping table not allowed for bitmap index

Hi,
looks like a feature available for standard Partitioned IOTs is not supported for object based tables, namely the MAPPING TABLE construct to support secondary local bitmap indexes.
Can you confirm behaviour is as expected/documented?
If so, is a fix/enhancement to support mapping table for object-based Partitioned IOTs in the pipeline?
Results for partition-wise load using pipelined table function are very good, look-ups across tens of millions of rows are excellent.

Thanks Dan,
the intention is to range partition based on the initial character, so A* -> Text_Part_A, B* -> Text_Part_B, and so on.
Here's an example, using an empty IOTObj_Table as created previously.

Tablespace Reorganisation in Oracle 10g Database

Dear All,
I'm planning of doing a carrying out a Tablespace Reorganisation of the schema tablespace on the production server. I need your views regarding the process to be taken and tuning that is required before carrying out such an activity. For your information, the size of the tablespace is around 3TB. Also, since it is the production server, we can't have an outage for more than 24hrs. Hence, I would like some help from all of you in order to carry out this activity successfully in the time frame.
Regarding the process :
I have some ideas about how to do the tablespace reorganisation in oracle 10g. But, if I carry out the activity my way, its going it to take atleast 3-4 days to complete (which won't be acceptable).
Areas of concern :
1) Steps to perform the tablespace reorganisation in Oracle 10g DB.
2) Size of the temporary tablespace before starting the Reorg.
3) Any further suggestions / recomendations regarding tuning up of Oracle Parameters for enhancement of speed and acuracy of the activity.
System Specifications :
SAP - BI 7.0 (SAP NetWeaver 2004s)
DB - Oracle 10.2.0.2.0, DBSL Patch Level - 158
OS - AIX 5.3
Looking forward to some good and prompt suggestions from all of you !!
Please provide your valuable inputs.
NOTE :: We have successfully performed the reorganization in the rest of the landscape on the same schema tablespace without any issues.
Thanks and Regards,
Deoraj Alok.

It is quite an old thread, but let me put in my view points, which could help others.
1. The Size of PSAPTEMP and PSAPUNDO tablespace should be 1.5*largest Table Size.
2. Another Important thing is , if the time is in an issue, what you can do is to reorg. only top 50 largest tables where maximum space is being wasted. Folowing is the query to determine the TOP 50 tables which has the highest WASTED size.
SELECT * FROM
(SELECT
SUBSTR(TABLE_NAME, 1, 21) TABLE_NAME,
NUM_ROWS,
AVG_ROW_LEN ROWLEN,
BLOCKS,
+ROUND((AVG_ROW_LEN + 1) * NUM_ROWS / 1000000, 0) NET_MB,+
+ROUND(BLOCKS * (8000 - 23 * INI_TRANS) *+
(1 - PCT_FREE / 100) / 1000000, 0) GROSS_MB,
ROUND((BLOCKS * (8000 - 23 * INI_TRANS) * (1 - PCT_FREE / 100) -
+(AVG_ROW_LEN + 1) * NUM_ROWS) / 1000000) "WASTED_MB",+
Tablespace_Name
FROM DBA_TABLES
WHERE
NUM_ROWS IS NOT NULL AND
OWNER LIKE 'SAP%' AND
PARTITIONED = 'NO' AND
(IOT_TYPE != 'IOT' OR IOT_TYPE IS NULL)
ORDER BY 7 DESC)
WHERE ROWNUM <=50;
I am sure that, only these 50 tables will reduce the maximum space and you can ignore rest of the tables.
3. Even you can find out all the Tables which are having LONG and LONG RAW fields by using this query
Select Distinct TABLE_NAME From dba_tab_cols Where Owner='SAPYSP' and (DATA_TYPE='LONG' OR DATA_TYPE='LONG RAW');
Now, from the results of this query you can see how many Tables are present in the Top 50 Tables. There will be a few only and you can export/import these few tables in offline mode.
4. After reorg, fi you want to claim the free disk space also, it would not be that easy because of the high water mark present in datafiles but you can try with
Alter datafile <datafile id> resize <Size>M
5. If free disk space is the first priority the you need to create another Table space (which should have size as big as it can have all the tables) and you re-organize in this new tablespace. After Reorg, drop the old tablespace and rename the new Table space with the old one (Rename Tablespace Command will work only in Oracle 10g).
I hope this information helps all those who are going to do reorg in their respective projects. However, You can further put your question if in doubt and I will try to answer them.

Segment organization within tablespace

Hi There,
I was trying to organize objects within the tablespaces and moving things around when I got up to this:
I needed to get rid of the PROD_T3 tablespace so I moved everything out of it apart from the below
SQL> select owner,segment_name,segment_type, TABLESPACE_NAME,bytes/1024/1204 from dba_Segments where tablespace_name='PROD_T3' order by 3;
OWNER                SEGMENT_NAME                   SEGMENT_TYPE       TABLESPACE_NAME                BYTES/1024/1204
PROD                 PK_VOTER_REG_DOC               INDEX              PROD_T3                          122.471761
PROD                 SYS_IL0000186869C00026$$       LOBINDEX           PROD_T3                          .053156146

SQL> select owner, index_name, table_name, tablespace_name, status from dba_indexes where index_name='PK_VOTER_REG_DOC';
OWNER                INDEX_NAME                     TABLE_NAME                     TABLESPACE_NAME        STATUS

SQL> desc prod.VOTER_REG_DOC
Name                                                                     Null?    Type

SQL> select count(*) from prod.VOTER_REG_DOC;
COUNT(*)
   3656468But when I look at dba_segments, I can't see it:
SQL> select owner,segment_name, segment_type , tablespace_name from dba_segments where owner='PROD' and segment_name='VOTER_REG_DOC' order by 1,2
no rows selected
SQL>
SQL> select owner,segment_name, segment_type , tablespace_name from dba_segments where owner='PROD' and segment_name like '%VOTER_REG%' order by 2,3;

PROD                 PK_VOTER_REG_DOC               INDEX              PROD_T3
SQL>Where am I going wrong with this? Also, I was surprised to see an object or a segment called "BIN$IEDOLJmsSj6isKTb5Z2cOQ==$0" ? I thought any BIN* would be sitting in DBA_RECYCLEBIN as the object(s) been deleted or am I wrong?
Appreciate the help.

I believe you will find that you are looking at the definition entry for an index organized table.
select IOT_TYPE from dba_tables where table_name = 'VOTER_REG_DOC'
if it returns 'IOT' then that is what you have.

Regarding Overflow segments in IOT

can any one please tell me what will be contents of the overflow segments in an IOT.
documentation says
An OVERFLOW clause, which preserves dense clustering of the B-tree index by storing the row column values exceeding a specified threshold in a separate overflow data segment. This data segment can be in another tablespace also.
An OVERFLOW clause, which preserves dense clustering of the B-tree index by enabling the storage of some of the nonkey columns in a separate overflow data segment.
during the insert operations if the data extent threshold limit is reached it alloates a overflow segment right..
in the documentation it also says that non key columns in the table are also stored in the overflow segments.
CAN ANY ONE TELL ME WHAT WILL BE THE CONTENTS OF INDEX SEGMENTS AND OVERFLOW SEGMENTS FOR THE FOLLOWING TABLE.
CREATE TABLE admin_docindex2(
token CHAR(20),
doc_id NUMBER,
token_frequency NUMBER,
token_offsets VARCHAR2(512),
CONSTRAINT pk_admin_docindex2 PRIMARY KEY (token, doc_id))
ORGANIZATION INDEX
TABLESPACE admin_tbs
PCTTHRESHOLD 20
INCLUDING token_frequency
OVERFLOW TABLESPACE admin_tbs2;

The contents of the oveflow segment will be all columns defined after the including token_frequency column, in your case the token_offsets column.
As definitions for all the remaining columns within the index structure are relatively small, the pctthreashold value of 20% is not likely to come into play.

Move large tables and indexes into own tablespace

I currently manage a 100Gb 10.2.0.4 SE database on Windows.
There is one data tablespace and one indexes.
I have one table xxxHistory that is periodically cleared out, however, six months of data must be retained.
The table is currently 17Gb and has 95 million rows, the corresponding nine or so indexes take another 47Gb.
I am having a small problem with I/O waits on this table so, I want to move this table and the indexes to their own tablespaces, which I will create (xxxHistory_D and xxxHistory_I).
I know the two methods, exp/imp (difficult due to foreign keys) and the prefered method of :
alter table tbl move tablespace tblsp and
alter index ind rebuild tablespace tblsp.
I have no problems with the syntax etc, having used this method many times.
My question is, does anyone have a better idea of how to approach this to minimise downtime?
The system cannot be used if this table is not available.
I am also going to migrate to 11.2x when available but can't find anything in the new features to help.
Note, this is SE, so partitioning is not an option and once I have sorted this table out, I will unchain the rows of any other and reorganise the space.
Disk space is not an issue.
Thanks,

Strategically this sounds as if you really do need partitioning; since you're on SE, you could consider the v7 "partition view" concept.
Create one table per month, and index each table separately.
Add a constraint to each table of the form: "movement date between to_date('...') and to_date('...')"
Create a union all view of the tables.
Getting rid of a single month means redefining the view.
In theory any queries you do should be able to filter predicate pushdown and thus eliminate redundant partitions, and also handle pushing joins down into the union all view. But that's something you would have to test carefully.
You could even create the tables as index organized tables - which may be the solution to your I/O wait problems - if your queries are about stock movement then all the movements for a given stock will be thinly scattered across the table, leading to one block I/O per row required. IOTs would give you an overhead on inserts, but eliminate waits on queries.

How to specify overflow clause for IOT

Hi,
I’m using OSDM v3.0.0.665
How do I specify ‘overflow’ clause for index organized table (IOT)?
I need to generate DDL something similar to this “ create table T1(…….) organization index..overflow".
In OSDM, when I open physical model and table properties ‘IOT properties’ tab, I can see dropbox for overflow segment but no values in drop box, it is blank.
I do have tablespace created in my physical model.
I’m able to generate DDL for IOT but does not have ‘overflow’ clause.
Thanks,
Vikas

David,
Thanks for your response.
After creating segment template, I’m able to generate overflow clause.
However I’m still not able to specify tablespace for both – IOT table and overflow segment.
If I specify tablespace for IOT (say T1) under ‘General’ tab and if I also specify overflow segment (with tablespace T2) under ‘IOT properties’ tab, I’d expect it to generate DDL with tablespace T1 for IOT and tablespace T2 for overflow.
However it generates DDL with overflow tablespace T1 and does not generate any tablespace clause for IOT. So, IOT is created in default tablespace for user.
I need DDL with tablespace clause for both – IOT as well as overflow segment.
Can you please help?
Also, how do I get rid of other storage clauses like PCTFREE, PCTUSED, MINEXTENTS, MAXEXTENTS etc..
Thanks,
Vikas

IOT move

You have to move/rebuild a partitioned IOT one partition at a time.
Issue a separate ALTER statement for each partition.

This seems to be consistent with what Bartek has.
Can anyone confirm, by running some of my original test case with and without CREATE TABLE privilege?
I'm sorry for asking for this final confirmation, unfortunately it would be quite painful for me to have some privileged user do that for me.

Nologging to Logging & Moving IOT

Hello,
Oracle ver. 8.1.6 on Linux.
Problem 1:
When converting an IOT from "nologging" to "logging"
Oracle didn't gave any error. But when i queried the dba_tables it still shows 'NOLOGGING'. However when i tried with ordinary( non-IOT) it works fine. How to go about it ?
Problem 2:
Will indexes ( including secondary indexes ) created on an IOT will reside along with the table ( like primary index )? When i tried moving the IOT from one tablespace to another only the primary indexes moved to the new tablepace. I am forced to rebuild the secondary indexes in the new tablespaces. Is there any method to take both ( primary & secondary ) to move to new tablespace in one command.
Thanks in advance.
Saji

I see following objects in USER_SEGMENTS. All of them are related to IOT indexes. Around 512 entries.

Create index without using temp tablespace

Hello,
i have a great table with over 2.000.000.000 rows. Therefor i want to create an index on column1:

If i execute this my temp tablespace will be used and if its full (max 20gb) the creation will be aborted.
Where is my fault to create the index?

(     "STR1" VARCHAR2(20 BYTE),
     "STR2" VARCHAR2(20 BYTE),
     "VAL" NUMBER
) SEGMENT CREATION IMMEDIATE
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
TABLESPACE "USERS" ;
And i want to get the values like this:
select str1,str2,val from SCHEMA.TABLE1 where str1 = 'TEST1' or str2 = 'TEST1'
If this is the complete definition of the table, and if (str1, str2) are unique, and this really is the only way you use the table, then it looks as if your STRATEGIC move would be to rebuild the table as a hash partitioned IOT with something like 128 partitions. Since you probably can't do that in the short-term you could create a hash partitioned index on the table (assuming you have paid the partitioning licence) with enough partitions that you can create each one separately. Something like:
SQL> create index t1_i1 on t1(n1, n2, n3) unusable global partition by hash (n1, n2) partitions 4;
Index created.
SQL> select index_name, partition_name from user_ind_partitions;
INDEX_NAME           PARTITION_NAME
T1_I1                SYS_P8713
T1_I1                SYS_P8712
T1_I1                SYS_P8711
T1_I1                SYS_P8710
4 rows selected.
SQL> alter index t1_i1 rebuild partition sys_p8713 online;
Index altered.
-- repeat for each partition in turnRegards
