doubt in a table subpartitioning

Hi gems... good evening...

I have a table that was previously only range partitions.
Now I changed it to the partitioning composite range-hash.

There are 6 partition tablespaces namely TS_PART1, TS_PART2... TS_PART 6.
The default tablespace of the schema is TS_PROD.

The table had following structure previously:


create the table ORDER_BOOK
(
CUST_ID NUMBER (10),
PROFILE_ID NUMBER (10),
PRODUCT_ID NUMBER (10),
SUB_PROFILE_ID VARCHAR2 (25).
DATE OF CASHFLOW_DATE,
NUMBER (24.6) OF EARNINGS.
constraint ORDER_BOOK_PK primary key (CUST_ID, PROFILE_ID, PRODUCT_ID, SUB_PROFILE_ID, CASHFLOW_DATE)
)
partition by range (CASHFLOW_DATE)
(
partition values ORDER_BOOK_PART1 less (TO_DATE (January 1, 2003 ',' DD-MM-YYYY "")) tablespace TS_PART1;
partition values ORDER_BOOK_PART2 less (TO_DATE (January 1, 2006 ',' DD-MM-YYYY "")) tablespace TS_PART2;
partition values ORDER_BOOK_PART3 less (TO_DATE (January 1, 2009 ',' DD-MM-YYYY "")) tablespace TS_PART3;
partition values ORDER_BOOK_PART4 less (TO_DATE (1 January 2012 ',' DD-MM-YYYY "")) tablespace TS_PART4;
partition values ORDER_BOOK_PART5 less (TO_DATE (1 January 2015 ',' DD-MM-YYYY "")) tablespace TS_PART5;
partition values ORDER_BOOK_PART6 less (TO_DATE (1 January 2018 ',' DD-MM-YYYY "")) tablespace TS_PART6
)
;
create index ORDER_BOOK_IDX on ORDER_BOOK (PRODUCT_ID, CASHFLOW_DATE);





Now, I did the following steps to change the existing partitions to the new partitions composite range-hash:

Start
DBMS_REDEFINITION. CAN_REDEF_TABLE
(uname = > 'DEMO_TEST',)
tNom = > "ORDER_BOOK"
options_flag = > DBMS_REDEFINITION. CONS_USE_PK);
end;
/


create the table INTERIM_ORDER_BOOK
(
CUST_ID NUMBER (10),
PROFILE_ID NUMBER (10),
PRODUCT_ID NUMBER (10),
SUB_PROFILE_ID VARCHAR2 (25).
DATE OF CASHFLOW_DATE,
NUMBER (24.6) OF EARNINGS.
constraint INTERIM_ORDER_BOOK_PK primary key (CUST_ID, PROFILE_ID, PRODUCT_ID, SUB_PROFILE_ID, CASHFLOW_DATE)
)
partition of range (CASHFLOW_DATE)
SUBPARTITION by hash (CUST_ID)
model SUBPARTITION
(
SUBPARTITION SP1 tablespace TS_PART1,
SUBPARTITION SP2 tablespace TS_PART2,
SUBPARTITION SP3 tablespace TS_PART3,
SUBPARTITION SP4 tablespace TS_PART4,
SUBPARTITION SP5 tablespace TS_PART5,
SUBPARTITION SP6 tablespace TS_PART6
)
(values less than P1 (to_date('01-01-2003','DD-MM-YYYY')) partition,
values of partition P2 lower (to_date('01-01-2006','DD-MM-YYYY')),
values of partition P3 lower (to_date('01-01-2009','DD-MM-YYYY')),
partition P4 values less than (to_date('01-01-2012','DD-MM-YYYY')),
values for partition P5 lower (to_date('01-01-2015','DD-MM-YYYY')),
values of partition P6 lower (to_date('01-01-2018','DD-MM-YYYY')))
allow the movement of the line;


Start
dbms_redifinition.start_redef_table
(uname = > 'DEMO_TEST',)
orig_table = > 'ORDER_BOOK ',.
int_table = > 'INTERIM_ORDER_BOOK ',.
options_flag = > DBMS_REDEFINITION. CONS_USE_PK);
end;
/


Start
DBMS_REDEFINITION.finish_redef_table
(uname = > 'DEMO_TEST',)
orig_table = > 'ORDER_BOOK ',.
int_table = > 'INTERIM_ORDER_BOOK');
end;
/




After I did the index with the LOCAL clause is to say local indexes.

But the problem is that... at the beginning when there is only the range partitioning, then the data will tablespaces corresponding score.

But after editing the table, fill the array results in consumption of space in partition as well as the default tablespace storage.
I checked the size of the storage space. Since I came to know about it.

The output of the USER_TAB_SUBPARTITIONS is correct... each subparts are in the corresponding storage spaces.

But the primary partitions (USER_TAB_PARTITION) are in the default tablespace.



Please help me... thanks in advance...

Yes - so why is it a surprise?

You have created a new table and storage for partitions has not specified then the default tablespace has been used. You did not specify tablespaces for subparts to each of them uses the specified tablespace.

Don't you see the difference between the original

partition ORDER_BOOK_PART1 values less than (TO_DATE('01-01-2003', 'DD-MM-YYYY')) tablespace TS_PART1,

and the new

(partition P1 values less than (to_date('01-01-2003','DD-MM-YYYY')),

  • Doubt PLSQL cursor table variable record

    Hi all

    My version of Oracle: Oracle 10 G

    I have a cursor, allows day:

    cursor c_emp
    is
    (select * from emp where empina = 10); -Now this * returns me 5 values, IE empid (100), (rahul) fname, lname (smith), sal (9000), deptid (10)

    Now, in my home, I have a cursor loop for example, like this:

    Start
    for rec_c_emp in c_emp
    loop
    ..
    ..
    ..
    end of loop
    end;

    Now my requirement is I need to capture these values(rec_c_emp.empid,rec_c_emp.fname,rec_c_emp.lname,rec_c_emp.sal,rec_c_emp.deptid) 5
    in a table that is to say i [0], I [1], I [2], I [3], I [4]

    Now please note that in the future my ' select * from emp' could make me more values and so I need to capture these values without changing my code.

    I hope that I clearly explained my problem, please help.

  • Doubt regarding accessible Table via DB link

    I have the following SQL code:

    Select * from tab1@db_link tab1, tab2
    where tab1.col1 = tab2.col2
    and tab1.col2 = 99;

    Can I make sure that Oracle provides data for:
    Select * from tab1 tab1@db_link
    where tab1 = 99;
    and then joined the data with tab2.

    What could be the most fast way to access the data in this way? Basically, I need to resolve a similar application.

    No not much difference. On both cases, oracle goes for the same plan. Here is a small test case

  • Find the right Partition for swap Partiton when there are PARTITION and SUBPARTITION

    Hi all

    I have a small problem:

    I want to find the right cause of partitions of the partition key.  I have a partition and a Subpartition (sample - table in annex).

    I leave the database to generate the partition (and name), the name is generated. I need to find for the exchange of partition

    the right of Partition has cause of a given value of the partition key (in this case EVOD_PART_DATE and 20141101 value).

    When I try to find the right partiton name, I would use generally not:

    SELECT DISTINCT dbms_rowid.rowid_object(ROWID) data_object_id
   FROM F_CONTRACT_EVENT
   WHERE  EVOD_PART_DATE = TO_DATE ('20141101','YYYYMMDD')

    Okay, I get 2 rows, I'm expecting one, but cause the result are the subpartions, I get this:

      SELECT *  FROM ALL_OBJECTS WHERE DATA_OBJECT_ID IN ( 155159,155154);

    I see:

    EVO_DM    F_CONTRACT_EVENT    SYS_SUBP4292    155159    155159    TABLE SUBPARTITION
EVO_DM    F_CONTRACT_EVENT    SYS_SUBP4287    155154    155154    TABLE SUBPARTITION

    First of all - the DOF you posted is INVALID - you do not specify a delayed segment creation for partitions. Specify you for the table.

    Also, you must remove the DEFAULT value - 1 for the partitioning column. The value '-1' cannot be converted to a valid date for the virtual partitioning column value.» The default value is useless and will give confusion around the year exception err when the exception should actually provide a NULL value for a column not null.

    The documentation explains how to use the EXCHANGE PARTITION and has the code example

    Maintenance of Partitions

    Exchange a Partition of a partitioned Table interval

    You can exchange of range partitions in a partitioned table interval. However, you must make sure that the partition of the interval was created before that you can swap partition. You can leave the database create the partition in the partition of the interval of locking.

    The following example shows an Exchange partition for the interval_sales table, range-partitioned using the monthly from partitions of 1 January 2004. This example shows how to add data to the table using charge Exchange partition for June 2007. Assume there is only a local index on the interval_sales table and equivalent index have been created on the interval_sales_june_2007 table.

    LOCK TABLE interval_sales  PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy'))  IN SHARE MODE;    ALTER TABLE interval_sales  EXCHANGE PARTITION FOR (TO_DATE('01-JUN-2007','dd-MON-yyyy'))  WITH TABLE interval_sales_jun_2007  INCLUDING INDEXES;

    Note the use of the FOR syntax to identify a partition that has been generated by the system. The name of the partition can be used by querying the *_TAB_PARTITIONS view of data dictionary to find the partition system-generated name.

    Given that the last paragraph? That's what showed Solomon.

    NOTE:-special attention to the FIRST paragraph. If you use segment carried OVER creating the partition you want to Exchange could NOT have been created yet.

    Make SURE that you lock the partition as the example shows, or you will get an exception if it has not been created.

    Also - we know NOT what PROBLEM you're trying to solve.

    If you exchange a PARTITION of a table subpartitioned your working table should actually be partitioned using the SAME parttioning as the subparts in the source table:

    See my response in this thread:

    https://forums.Oracle.com/forums/thread.jspa?threadID=2482090&TSTART=30

    In this thread I have provide the code example illustrating how the table should be created and made Exchange.

  • How to change the default attributes for an index for a subpartition without data in it

    Hello

    The use of oracle 11.2.0.3 attributes and modifydefault for a partition, for example the tablespace can but can not use the same syntax for a subpartition.

    Is it possible to change the default attributes for a subpartition?

    ALTER index RTRN_CUR_CONV_IDX change the default attributes for the subpartition SYS_SUBP64934 RTRN_PART_201505 tablespace

    Thank you

    Refer to the section of the doc "a Subpartition template editing.

    http://docs.Oracle.com/CD/B28359_01/server.111/b32024/part_admin.htm#i1007904

    A Subpartition template editing

    You can change a model of a composite partitioned table subpartition by replacing it with a new model of subpartition. All subsequent operations that use the subpartition template (such as ADD PARTITION or MERGE PARTITIONS ) will now use the new subpartition template. Existing subpartitions remain unchanged.

    If you change a subpartition of a range model * composite partitioned table, then of range partitions that have not yet been created will use the new subpartition template.

    Use of the ALTER TABLE ... SET SUBPARTITION TEMPLATE statement to specify a new subpartition template. For example:

    You will need to 'fix' the new model as in the doc example.

    By the example of partitions with just a line in them, we find the secondary partition with data correctly a tablespace name as expecetd, but 4 other secondary partitions always show the name of the default tablespace in user_ind_subpartitions.

    Any idea whay and if can change

    Change the template affects only the created NEW partitions/subpartitions. If you want existing subpartitions to a different tablespace, you will need to move it.

  • Segments subpartions seems to also be moved when table sub-parts are moved

    Hello

    I have the script that dynamically generates the code to move subpartitions to one tablespace to another:

    Select
    'alter table ' | p.TABLE_OWNER | '.' || p.table_name | "move subpartition ' | p.subpartition_name | "tablespace LOCAL2_D;" text
    Of
    dba_tab_subpartitions p
    where
    p.tablespace_name in ('LOCAL1_D', 'LOCAL1_I');

    The generated code is as follows:

    ALTER table OBD_OWN. DWH_PREMIES move subpartition DWH_PRE_RLP_2010_Q1_1891 LOCAL2_D tablespace;

    Yet, when one do a check against the segments with this script:

    Select
    owner of s.Owner,
    type of s.segment_type,
    Count (*) rest_segs
    Of
    s dba_segments
    where
    s.tablespace_name in ('LOCAL1_D', 'LOCAL1_I')
    Group
    s.Owner,
    s.segment_type
    order by
    1, 2, 3;

    I see a reduction in the amount of the subpartitions table, which is an expected result, but also a decrease in the index sub-parts:

    -To time 1:

    OWNER TYPE REST_SEGS
    -------------------- ------------------------------ ---------
    OBD_OWN 30 INDEX
    OBD_OWN INDEX 16 180 PARTITION
    OBD_OWN INDEX SUBPARTITION 8 161
    PARTITION TABLE OBD_OWN 695
    OBD_OWN TABLE SUBPARTITION 593

    -By 2:

    OWNER TYPE REST_SEGS
    -------------------- ------------------------------ ---------
    OBD_OWN 30 INDEX
    OBD_OWN INDEX 16 180 PARTITION
    OBD_OWN INDEX SUBPARTITION 7 874 < = decrease in the unexpalined of these segments of type?
    PARTITION TABLE OBD_OWN 695
    OBD_OWN TABLE SUBPARTITION 586 < = decrease expected of segments in the tablespace crossing

    When you MOVE a Table Partition / SubPartition, the corresponding Index Partition/SubPartition becomes UNUSABLE.

    In 11.2, the Segment for a UNUSABLE Index/Partition/SubPartition is actually diminished - it restores the behavior "deferred_segment_creation".

    The segment is created when you run the ALTER INDEX REBUILD PARTITION indexname | Partition SUBPARTTION | SUBPARTITION name.

    https://support.Oracle.com/epmos/faces/UI/km/SearchDocDisplay.JSPX?ID=258597.1&type=document&DisplayIndex=1

    The short version is: you cannot specify physical attributes such as compression for an individual subpartition. You will have to do for the whole score (or even the entire table).

    We have succeeded by using the syntax of PARTITION for tables partitioned, but not sous-partitionnee.

    Any ideas?

    Thank you

    Support of Oracle reproduced this issue. The resolution was to ensure cursor_sharing is set to "EXACT", we happened to use "SIMILAR" in this case due to a migration of 10 g and 11 g.

  • SUBPARTITION templates

    How can I copy templates subpartition of a table to another table in the physical model of OSDM?

    I need to create a relatively large number of subpartition templates and I have to do for several tables. They have all of the similar subpartitions.
    Can I create templates for subpartition to a table and copy and paste those to the other tables?
    Otherwise, there is no alternative workaround to avoid creating for each table subpartition templates?

    I use v3.1EA3

    Hello

    The expression of the interval you specified,

    1)
    (VALUES LESS THAN (1) PARTITION

    is not a valid interval expression.

    You must set the Expression of the interval 1.

    If you want to generate the PARTITION VALUES LESS THAN clause (1), you should add a Partition for the Table object in the physical model and set its property to list the value to 1.

    I would like to replicate tables between 2 instances in 2 different hosts. Mixed 11 GR 1 material and Oracle 10 g 2. I have my doubts:

  • Bug in Array Function XNodes 1.4.0.24?

    Hello

    I have been using Array Function XNodes 1.4.0.24 for a while now and find it quite useful.

    However, I have met unexpected behavior which makes me doubt the filter table node (and so the whole package).

    The matrix of results 'False elements' of the node is too large, filled with identical nonsensical data after the apparently correct data elements.

    The amount of padding data depends on the array of Boolean.

    My input array is U8. Its size seems to be the problem. If it is less of a factor of 100 the vi will work as expected.

    Anyone who has installed the package can check this behavior with the vi attached?
