Tablespace move in partitioned tables

I moved partitioned tables in new tablespace dedicated for 2006 data, do i need to move table relaed indexes in new tablespace also.?

No,
global Indexes will be invalid and have to be rebuild. If you have local Indexes you only have to rebuild the affected partitions. Nothing else to do.

How to move a partitioned table

Hi,
i have a partitioned table where i am inserting records using direct-path and deleting records( no conventional load) . Now coz of deletions there are many blocks that are free below High Water Mark. so it thought of moving table from one tablespace to another tablespace.

ANy other way to reclaim those free space below HWM? i am in 9i R2
Thanks in advance

I have a table partitionned and I want to drop the tablespace for a specific partition. So what happen in the table if I drop one tablespace with a commande drop tablespace tbs including contents and datafiles;
Does the index unusable in this table?

No, you can not drop a tablespace which contains tables whose partitions are not completely contained in this tablespace.

Tablespace of a partitioned Table

Hi,
what is the meaning of the outer tablespace clause in a 'create table' statement, when in the table the tablespaces are defined for each partition?
f.e.:
create table PST_ER_ZIEL (
ID NUMBER(18) not null,
PST_ZIEL_ID NUMBER(9) not null,
PST_NODE_ID NUMBER(9) not null,
MESSOBJECT VARCHAR2(100) not null,
VSTKNR VARCHAR2(11) not null,
EVENT_STATUS NUMBER(2) not null,
EVENT_TIME DATE not null
partition by range
EVENT_TIME
partition
Day1
values less than
TO_DATE('2003: 2' , 'YYYY: DDD')
tablespace PST_EV_RT,
partition
Day2
values less than
TO_DATE('2003: 3' , 'YYYY: DDD')
tablespace PST_EV_RT
tablespace DATA1;
What will be stored in DATA1 after creating the table?
Thanx,
Balazs

The outer tablespace clause is the 'default' tablespace for new partitions. When you add a new partition without adefinition for a tablespace, it is stored in DATA1.

Migrating a new partition table with transportable tablespace

I created a partitioned table with 2 partitions (2010 and 2011) and used transportable tablespace to migrate the data over to a new envionment. My question is, if I decide to add a partition (2012) in the future, can I simply move that new partition along with the associated datafile via transportable tablespace or would I have to move all the partitions (2010, 2011, 2012).

1) create a table as CTAS from 2012 in new Tablespace on source
2) transport the tablespace
3) Add partition to existing partition table Or exchange partition
Oracle has also documented this procedure:

Tablespace about partitioned table

Guys,
I've had some issues with the partitioned tables. Scenario is like this..
I have had a table, which was partitioned. I had to move all the partitions of this table to a new one, which worked fine and dropped the old tablespace. But now when i try to split the partition, the table still referes to the old tablespace name at a higer level. How do i change this..
I am refering to the USER_DATA on top, which is the default tablespace for the user.
It looks something like :

I've done this before but I couldn't find it quickly... hence I thought it was the MOVE TABLESPACE clause. But now I think what I did was:

How to import partitioned tables in different tablespace

Hi everyone,
I try to import the partitioned tables in different tablespace.
Consider the following situation:
I have a dump file which is created by using "Export" utility. Some data are in partitioned tables, some of them are in non-partitioned tables. Also, all tables are located in "MYTBS" tablesapce. I try to import all data from this dump file to another database. I didn't get error messages when importing the data from non-partitioned tables. However, I got error message when importing the data from partitioned tables. The error message is: tablespace 'MYTBS' does not exist.
I just want to how I can solve this problem other than create 'MYTBS' tablespace for my new database.
Thanks in advance.

Oracle 11gR2 Partition tables not creating in default user tablespace

Hi all:
Not sure if i'm missing something or overlooked but when i create a partition table in a user schema, it is not creating in the schema's default tablespace instead creating with no assigned to any and using SYSTEM tablesspace.
create user dgp identified by dgp default tablespace dgp temporary tablespace temp;
grant connect, resource to dgp;select USERNAME,DEFAULT_TABLESPACE from dba_users where username ='DGP';
USERNAME DEFAULT_TABLESPACE
DGP DG
select table_name, tablespace_name, partitioned from all_tables where owner='DGP';
TABLE_NAME TABLESPACE_NAME PAR
AUDITLOG_P2 DG NO
AUDITLOG_P YES
This is the partition script i used --i also gave the tablespace name:
CREATE TABLE dgp.AUDITLOG_P(
entry_time DATE,
username VARCHAR2(14),
groupname VARCHAR2(100),
ip VARCHAR2(15),
command VARCHAR2(15),
directory VARCHAR2(300)
PARTITION BY RANGE (entry_time)
partition P_PAST VALUES LESS THAN (TO_DATE('2010-01-01','YYYY-MM-DD')),
tablespace DG;
============
What is it i'm missing? Anything different with Oracle 11gR2 on the partition creations?
Thanks for your help..

How to move all the tables from one tablespace to other for a whole schema

Hi,
Is there any way to move all the tables in a schema from one tablespace to other?
If so please help me out to do that.
Thanks
Regards
Gatha

hi,
here is the steps to move SCOTT's objects from their current tablespace to a NEW_TABLESPACE
would be:
1) do an export of all of scott's objects. Make sure no one modifies them after you
begin this process. You will lose these changes if they do.
$ exp userid=scott/tiger owner=scott
2) you would drop all of scotts tables. This will get the indexes as well. I don't
suggest dropping the user SCOTT but rather dropping scott's objects. Dropping scott
would cause any system priveleges SCOTT has to disappear and the import would not restore
them. This script can be used to drop someones tables:
set heading off
set feedback off
set verify off
set echo off
spool tmp.sql
select 'drop table &1..' || table_name || ' cascade constraints;'
from dba_tables
where owner = upper('&1')
spool off
@tmp.sql
3) You would modify the user to not have unlimited tablespace (else the IMP will just
put the objects right back into the tablespace they came from) and then give them
unlimited quota's on the new tablespace you want the objects to go into and on their
temporary tablespace (for the sorts the index creates will do)
alter user SCOTT default tablespace NEW_TABLESPACE
revoke unlimited tablespace from SCOTT
alter user SCOTT quota unlimited on NEW_TABLESPACE
alter user SCOTT quota unlimited on SCOTTS_TEMPORARY_TABLESPACE
4) you will IMP the data back in for that user. IMP will rewrite the create statements
to use the users default tablespace when it discovers that it cannot create the objects
in their original tablespace. Please make sure to review the file imp.log after you do
this for any and all errors after you import.
imp userid=scott/tiger full=y ignore=y log=imp.log
5) you can optionally restore 'unlimited tablespace' to this user (or not). If you do
not, this user can only create objects in this new tablespace and temp (which in itself
is not a bad thing)...

Assigning dedicated tablespaces to partitioned table 11g

Hi,
I'm facing an issue trying to assign a dedicated tablespace to a range partitioned table using the NUMTOYMINTERVAL clause.
I'm working on Oracle 11g version and I would use the auto partition creation feature in order to create
each month a new partition to use in a log table.
Using the create statement, all work fine.
If I try to use the alter table statement, i got an error.
I understand that i cannot add a new partition (Oracle automatic feature)
but I need to assign a dedicated tablespace to the new partition Oracle is going to create.
Someone could help me?
Thank you in advance.

Adding an example on MyTable:
CREATE TABLE "MyTable"
(     "ID" NUMBER,
     "CREATION_DATE" TIMESTAMP (6) DEFAULT SYSTIMESTAMP,
     "PARTITION_DATE" DATE DEFAULT TRUNC(SYSDATE),
     "TIMESTAMP" VARCHAR2(50 BYTE),
     "FAULT_GENERATING_REQUEST" CLOB
PARTITION BY RANGE(PARTITION_DATE)
INTERVAL(NUMTOYMINTERVAL(1,'MONTH')) STORE IN (LOGTBS0512,LOGTBS0612,LOGTBS0712,LOGTBS0812)
     (PARTITION NEWCO_P_LOG0512 VALUES LESS THAN (TO_DATE('01-05-2012', 'DD-MM-YYYY'))
TABLESPACE LOGTBS0512
LOB ("FAULT_GENERATING_REQUEST") STORE AS(TABLESPACE LOG_LOB_0512 cache storage(freelists 10)),
PARTITION NEWCO_P_LOG0612 VALUES LESS THAN (TO_DATE('01-06-2012', 'DD-MM-YYYY'))
TABLESPACE LOGTBS0612
LOB ("FAULT_GENERATING_REQUEST") STORE AS(TABLESPACE LOG_LOB_0612 cache storage(freelists 10)),
PARTITION NEWCO_P_LOG0712 VALUES LESS THAN (TO_DATE('01-07-2012', 'DD-MM-YYYY'))
TABLESPACE LOGTBS0712
LOB ("FAULT_GENERATING_REQUEST") STORE AS(TABLESPACE LOG_LOB_0712 cache storage(freelists 10)),
PARTITION P_LOG0812 VALUES LESS THAN (TO_DATE('01-08-2012', 'DD-MM-YYYY'))
TABLESPACE LOGTBS0812
LOB ("FAULT_GENERATING_REQUEST") STORE AS(TABLESPACE LOG_LOB_0812 cache storage(freelists 10));

Should we have to mention tablespace while we partition a table???

Should we have to mention our new tablespace while we partition a table???

You can create a table with multiple partitions and put all each those partitions into one tablespace
Take a look at this example:
http://www.oracle-dba-online.com/sql/oracle_table_partition.htm
And from Documentation:
Although you are not required to keep each table or index partition (or subpartition) in a separate tablespace, it is to your advantage to do so. Storing partitions in separate tablespaces enables you to:
Reduce the possibility of data corruption in multiple partitions
Back up and recover each partition independently
Control the mapping of partitions to disk drives (important for balancing I/O load)
Improve manageability, availability, and performance

Local Vs Global Index on partitioned table?

Hello All,
DESC PS_P1_EMP_QRYSCRTY
Name Null? Type
EMPLID NOT NULL VARCHAR2(11)
EMPL_RCD NOT NULL NUMBER(38)
ROWSECCLASS NOT NULL VARCHAR2(30)
ACCESS_CD CHAR(1)
MY SQL QUERY IS:-
SELECT DISTINCT OPR.OPRID , EMP.EMPLID ,EMP.EMPL_RCD , OPR.CLASSID ,'Y'
FROM PS_SJT_OPR_CLS OPR , PS_P1_EMP_QRYSCRTY EMP
WHERE EMP.ROWSECCLASS=OPR.CLASSID
This query was taking around 15 mins to run at sql-prompt
I have created a partitioned table based on PS_P1_EMP_QRYSCRTY :-
CREATE TABLE PS_P1_EMP_QRYSCRTY_BAK
TABLESPACE PSNEWTAB
PARTITION BY HASH(ROWSECCLASS)
( PARTITION PART1 ,
PARTITION PART2 ,
PARTITION PART3 ,
PARTITION PART4 ,
PARTITION PART5 ,
PARTITION PART6 ,
PARTITION PART7 ,
PARTITION PART8 ,
PARTITION PART9 ,
PARTITION PART10 ,
PARTITION PART11 ,
PARTITION PART12 ,
PARTITION PART13 ,
PARTITION PART14 ,
PARTITION PART15 ,
PARTITION PART16
ENABLE ROW MOVEMENT
AS SELECT * FROM PS_P1_EMP_QRYSCRTY
I created a local index like on PS_P1_EMP_QRYSCRTY_BAK
CREATE INDEX PS_P1_EMP_QRYSCRTY_BAK
ON PS_P1_EMP_QRYSCRTY_BAK(ROWSECCLASS,EMPLID,EMPL_RCD)
TABLESPACE PSINDEX
LOCAL;
The Following is an extract From PS_P1_EMP_QRYSCRTY_BAK
1ST COLUMN =TABLE NAME
2ND COLUMN = PARTITION NAME
3RD COLUMN = NUM OF DISTINCT ROWSECCLASS IN THE PARTITION
4TH COLUMN = NUM OF TOTAL ROWS IN THE PARTITION
TABLE_NAME PARTITION_NAME NUM_OF_DISTINCT_ROWSECCLASS NUM_OF_ROWS
PS_P1_EMP_QRYSCRTY_BAK | PART1 | 25 | 289058

PS_P1_EMP_QRYSCRTY_BAK | PART15 | 21 | 259676
PS_P1_EMP_QRYSCRTY_BAK | PART16 | 23 | 468071
SELECT DISTINCT OPR.OPRID , EMP.EMPLID ,EMP.EMPL_RCD , OPR.CLASSID ,'Y'
FROM PS_SJT_OPR_CLS OPR , PS_P1_EMP_QRYSCRTY_BAK EMP
WHERE EMP.ROWSECCLASS=OPR.CLASSID
Now when i run this query it gives result in around 5-6 mins
MY PS_P1_EMP_QRYSCRTY_BAK table contains sumwhat 6 million rows...
Now My Questions are:-
1) Is the number of partition done by me optimal under these circumstances...i mean can i get better performance By increasing or decreasing the number of partitions.
2) I created local index on PS_P1_EMP_QRYSCRTY_BAK.
Whether creating local or global index will be more beneficial keeping in mind the where clause and Select clause of the query....
SELECT DISTINCT OPR.OPRID , EMP.EMPLID ,EMP.EMPL_RCD , OPR.CLASSID ,'Y'
FROM PS_SJT_OPR_CLS OPR , PS_P1_EMP_QRYSCRTY_BAK EMP
WHERE EMP.ROWSECCLASS=OPR.CLASSID
i mean in where clause rowsecclass is used thats why i partitioned my table on ROWSECCLASS.
And in select clause i m selecting EMPLID and EMPL_RCD
Thats y i made a local index on ROWSECCLASS,EMPLID ,EMPL_RCD .
Thanks

Your query
SELECT DISTINCT OPR.OPRID , EMP.EMPLID ,EMP.EMPL_RCD , OPR.CLASSID ,'Y'
FROM PS_SJT_OPR_CLS OPR , PS_P1_EMP_QRYSCRTY_BAK EMP
WHERE EMP.ROWSECCLASS=OPR.CLASSIDappears to read all qualifying rows across all qualifying partitions. Since you are partitioning by an id that would appear to exclude range and list partitioning instead so the hash partition is probably the best for your application.
Regarding global vs local partitions, I have seen timings indicate that global indexes can improve cross-partition queries slighly. I have not worked with partitions for a while but remember that global partition maintenance is difficult; anything the partition structure changes the global index had to be rebuild. You can check the documentation to see if that has changed.
If possible creating a unique index should give better performance than using an index allowing duplicates.
