Split Max partition

I've 20gb table which has been partitioned by range (yearly basis ans quaterly basis).
And most of the data has been stored in the max partition and segment size is increasing faster.
Now I want to get rid of max partition and divide the table with more partitions which would capture data yearly.This way I can have only 2 years worth data on production and partition can be dropped easily after moving to datawarehouse .
Kindly suggest.Partitions I want to split is yearly like
"PARTITION "2008" VALUES LESS THAN (TO_DATE(' 2009-01-01 00:00:00',
TABLESPACE "LLS_DATA01" NOCOMPRESS"
Below is the table desc
CREATE TABLE "LLS"."test"

Diskutil problems when trying to split mac partition

I'm having some serious issues trying to get my mac to partition properly. I think my computer hates me. Anyways, when I try to use diskutil to split my partition up into four partitions i get an odd error that I can't find anywhere online - it says "Resizing encountered error on disk disk0s2 MacOSX: Operation not supported by device (19)", the diskutil list displays:
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUIDpartitionscheme *149.1 Gi disk0
1: EFI 200.0 Mi disk0s1
2: Apple_HFS MacOSX 148.6 Gi disk0s2
and the command I've run is:
sudo diskutil resizeVolume disk0s2 60G "Ext2" "Linux" 20G "NTFS" "Windows" 68G
and I've installed plugins to handle the Ext2 and NTFS formats, so I have no freaking clue what's going on, please help! Thank you very much in advance!

You have to specify the numberOfPartitions you are adding:
sudo diskutil resizeVolume disk0s2 60G 2 "Ext2" "Linux" 20G "NTFS" "Windows" 68G

AVOID Subpartition(list) to be created when Splitting Main Partition(range)

I have created a table structure as below:
CREATE TABLE TEST_SUBPARTITIONS_1
RECORD_ID INTEGER NOT NULL,
SUB_ID VARCHAR2(100),
COBDATE DATE,
DESC VARCHAR2(2000)
PARTITION BY RANGE (COBDATE)
SUBPARTITION BY list(SUB_ID)
PARTITION INITIAL_PARTITION VALUES LESS THAN (TO_DATE(' 2200-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE TBS_DATA
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE
INITIAL 64K
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
(SUBPARTITION INITIAL_SUBPARTITION VALUES ('INITIAL_DUMMY_SUB_ID') TABLESPACE TBS_DATA
CREATE UNIQUE INDEX TEST_SUBPARTITIONS_1_PK ON TEST_SUBPARTITIONS_1 (COBDATE, RECORD_ID, SUB_ID) LOCAL;
ALTER TABLE TEST_SUBPARTITIONS_1 ADD CONSTRAINT TEST_SUBPARTITIONS_1_PK PRIMARY KEY (COBDATE, RECORD_ID, SUB_ID);
I am partitioning the table based on range (COBDATE) and subpartitioning based on list (SUB_ID).
The table now is created with initial partitions and initial subpartition.
We are splitting the partitions in our procedure as below
ALTER TABLE TEST_SUBPARTITIONS_1 SPLIT PARTITION
TST_SUB_R21001231 AT (TO_DATE(20130220,'YYYYMMDD') ) INTO
     (PARTITION TST_SUB_R20130219 TABLESPACE TBS_DATA, PARTITION TST_SUB_R21001231)
The partition is getting split correctly with new partition as
TST_SUB_R20130219, but the subpartition is also created automatically with some 'SYS' name.
(i.e Name: SYS_SUBP693 , Values: INITIAL_DUMMY_SUB_ID)
This happens after every split of range by COBDATE.
Here it has created as below:
Partition          SubPartition
TST_SUB_R21001231     INITIAL_SUBPARTITION
TST_SUB_R20130219     SYS_SUBP693
TST_SUB_R20130220     SYS_SUBP694
TST_SUB_R20130221     SYS_SUBP695
I want to AVOID splitting subpartition when I split the main partition
i.e a SYS subpartition should not be created when I split the partition for COBDATE.
Let me know how do I avoid this in main "alter statement" above?
Any other solution?     I do not want to drop the SYS subpartition later, instead want it to avoid creating only when I split the partition.

The subpartitions aren't being split. Oracle is creating new subpartitions for the new partition. The subpartitions need to exist since that is where the data is stored.
You can avoid the SYS prefix on the name though by using a different naming convention.
See the 'Splitting a *-List Partition' section of the VLDB and Partitioning Guide

>
The ALTER TABLE ... SPLIT PARTITION statement provides no means of specifically naming subpartitions resulting from the split of a partition in a composite partitioned table. However, for those subpartitions in the parent partition with names of the form partition name_subpartition name, the database generates corresponding names in the newly created subpartitions using the new partition names. All other subpartitions are assigned system generated names of the form SYS_SUBPn. System generated names are also assigned for the subpartitions of any partition resulting from the split for which a name is not specified. Unnamed partitions are assigned a system generated partition name of the form SYS_Pn.

Can't boot into Windows after splitting Mac partition with Disk Utility

Hi everyone,
I installed Windows 8 with BOOTCAMP, creating a large 871 GB partition with a smaller 127 GB partition for Windows. After installing Windows, I then went back to Disk Utility to shrink the Mac partition and add two new partitions, one for storage and another blank, hoping to use it to install Linux into one day.
I did that, and now Windows doesn't boot. A Windows blue screen tells me I need to use the Windows DVD to repair it.
I tried to use Disk Utility to delete the two new partitions I made and grow the Mac partition back to the max size of 871 GB. But it doesn't let me do this. The Disk Utility log doesn't report an error and thinks it worked but the partition stays the same size. However if I make the partition a little smaller, like 870 GB then it works. I'm wondering if the Recovery partition is hiding there and preventing me from fully expanding the Mac partition.
What can I do?

Kappy,
I can boot into OS X just fine so if possible, I'd like to avoid reformatting everything. If you know of a way I can add more than 2 partitions with OS X and Boot Camp, please let me know. As far as I know, rEFInd can recognize more than two partitions, but I don't think it can edit partitions on a GPT / hybrid MBR system. Or am I wrong?

Best way to split large partition in multiple small partitions

Looking for some ideas here. We ended up having a large/huge partition, the last one (because of maxvalue), while other partitions have similar number of records. What's the best way to split this large partitions with has about 3 years worth of data into separate partitions based on Month/Year. I tried with SPLIT partition, I not able to figure out a way to specify a value where I can like to split.
Any thoughts, ideas appreciated.
Thanks

I'd be inclined to split off that partition as a stand-alone table. Create new partitions and then reload the data. But that "inclined" would depend on the available maintenance window and the amount of data and the Oracle version number none of which you mention.

Why I cannot split a partition table whose partitions are in a tablespace?

Splitting table partition

Hi All,
I have a table with several partitions. The latest partition (key is date column) has values less than MAXVALUE. The table has several local indexes on it. It's too large and I'd like to split the latest partition. I have the following questions:
1. Can I simply split the partion and expect everything to work
2. What about indexes, do I have to re-create them or will they be split along with the table ?. I'd like to specify a new tablespace for the newly partitioned index. How can I do that
3. How can I specify a tablespace for the newly partition data ? Should I move the rows between tablespaces after the split
4. Can anyone share any experience with me.
The database is Oracle 9i. Any help is higly appreciated.
Thanks a lot
Vissu

1. Yes, it works fine
2. Yes u have to recreate the index
alter index my_index rebuild partition my_partition tablespace new_tablespace ;
3. check the syntax of the split partition command :-)
4. Yes :-) all works really fine, i have ever split partition, exchange partition, everything works really fine

Splitting a Partition into smaller Volumes

Hi,
On an external drive I have 3 partitions. One of these is an empty 250gb partition. I'd like to split that into smaller 15gb sized partitions for some multiple install testing. In disk utility I have selected the partition and clicked the + sign to add a new one and so on until I had the rquired amount. I then selected new names and sizes (15gb) for each partition.
Firstly, it failed with this error "The chosen size is not valid for the chosen filesystem".
So, I decided to add one partition at a time. This worked. However, the 15gb partition is now only 9.46gb. A 5gb loss seems a bit excessive. Does this seem right?
Thanks

Thanks Steve. I figured that was the case. I must be doing something wrong (or my brain isn't working correctly today.) It seems that this should be a really easy thing to do - take one long segment, and break it into smaller segments. But I can't use anything in the clip menu, and the only way I figured out to save the individual clips as their own files is to delete everything else, and then save. Clip #2, select clip, delete everything, save. Seems kinda stupid to me. But, again I must be doing something wrong.

Splitting List partition

Hi all,
We are using oracle database (10.2.0.4 64bit) and OS AIX (6.1).
We have list partition table. On column sale two values (1 or 0) are stored.
Table has two partition DAILY_ISSUANCE_SALE_FACT_1 for value (1) and DAILY_ISSUANCE_SALE_FACT_0 for value (0).
Due to huge size of table, we want to split partition DAILY_ISSUANCE_SALE_FACT_1 and DAILY_ISSUANCE_SALE_FACT_0.
How I can splite these two partitions with values 1 and 0?

You can't - a list partition whose definition only specifies one value cannot be split. If you have specified a DEFAULT partition for the table you can split that default partition but that won't affect the two partitions that you mentioned.
You could also add a new partition but that won't affect those two partitions either.
See the 'Maintaining Partitions' section of the VLDB and Partitioning Guide
http://docs.oracle.com/cd/E18283_01/server.112/e16541/part_admin002.htm#i1007318
That section has details and examples of how to add/split partitions.
Due to huge size of table, we want to split partition
Why? What are you trying to accomplish? What difference does it make if the table is 'huge'? Can you tell us precisely when the table became huge? Does that mean that the day before it was not huge but that now it is?
Large tables are generally partitioned to either improve performance of queries or to improve the performance of maintenance operations (e. g. delete/remove older data, add new daily data).

How to split huge partition

hi !
i have partitioned table:
create table t1 (d date)
partition by range (d)
partition p_min values less than (TO_DATE(' 2006-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')),
partition p_01 values less than (TO_DATE(' 2007-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')),
partition p_02 values less than (TO_DATE(' 2008-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')),
partition p_max values less than (maxvalue)
);the problem is: my p_max partition grow to >500GB and split it into several P_% partitions takes ages. how can i do it in the most efficienf and fast way ?
my database is 10.2.0.2@hp-ux 11.23, 4cpu
thank you for help.

Hello,
How much data I mean volumewise you got in P_MAX partition and when you split up how much time it took?
Another approach will be wholesome just create another partitioned table with all the old partitions as compressed (so they save you storage and give some boost to query), offcourse if you are not perfoming heavy DML on old partitions.
1. Create a new empty partitioned table with old partition as compressed.
2. insert into new_part_table select * from old_part_table; Use APPEND hint to speed up and compression benefit.
3. Drop old indexes and recreate in new partitions.
Another approach you already mentioned making use of exchange partitions.

Solaris 10 Max Partition size

Hi,
I would like to know the maximum partition size that Solaris 10 can support/create.
We have a Sun StorEdge 6920 system with a 8 TBytes, based on 146 GBytes Hard Disks.
Is it possible to create a 4 TBytes partition?
if not, any suggestions are appreciated.

Look to EFI, allows filesystems built to large TB sizes if you needed.
Per SUN:
Multi-terabyte file systems, up to 16 Tbyte, are now supported under UFS, Solaris Volume Manager, and VERITAS's VxVM on machines running a 64-bit kernel. Solaris cannot boot from a file system greater than 1 Tbyte, and the fssnap command is not currently able to create a snapshot of a multi-terabyte file system. Individual files are limited to 1 Tbyte, and the maximum number of files per terabyte on a UFS file system is 1 million.
The Extensible Firmware Interface (EFI) disk label, compatible with the UFS file system, allows for physical disks exceeding 1 Tbyte in size. For more information on the EFI disk label, see System Administration Guide: Basic Administration on docs.sun.com. "
Found this at:
http://www.sun.com/bigadmin/features/articles/solaris_express.html
So you may want to look into EFI, which is different way of partitioning the disk.

Range Partitioning a table. Max value to be defined

Hi,
I am using a range partitioned table, range partitioned on date, and have defined max value as 6 months after the Creation Date.
I have a proc which creates the partitions I want in advance by splitting up the max partition.
- Now what do I do when max partition is reached after 6 months?
- If I define max partition one year or two year after the current date instead of the currently defined 6 months after creation date. What are the negatives attached with it?
I can't use Interval Partition and have to use Range only.
Kindly suggest.
Thanks..

Any data with a partition key that does NOT match any partition will cause your INSERT query to fail.
Any partition that has no data to match it will simply remain empty.
A common partitioning scheme is to define one partition for all old data, one partition with a high max value and then split the max value partition to get the partitions you want in the middle.
Let's say you want monthly partitions but don't have that much data from before the current year, 2012.
1. Create one partition for dates < 1/1/2012
2. One partition each for the 12 months of 2012
3. One max value partition to be 1/1/4000
You would just split the max value partition to create each month of 2013. The split could be done ahead of time or a month at a time as you choose.
The only negative is that any data inserted by mistake that has a super-high date will go into the max value partition. But that is going to happen anyway. If you accidentally enter a date of 3/23/3882 it won't be rejected.
But it is easy to query periodically to see if you have any 'bad' data like that. And the alternative is that an INSERT would fail because of the one bad record and all of your good data would be rejected anyway so it's not really much of a negative.
Remember - for best management performance each partition should have its own tablespace and the indexes should all be local if possible.

Split Oracle 11g Table Partition and Insert new rows

Hi,
I have a doubt that i would like to be clarified. I need to split a partition of a table with more than 800 Million records, but at the same time (during the split operation) i need to insert new records (not in the partition that is being splited). Is there any problem/risk doing this? Is the insert ETL process going to fail ?
Thanks in advance
Greetings.
Nuno

Hi Enrique,
Thanks for posting in MSDN.
Based on the description, you want to modify the formula for the A1 and B1 cell when you insert a new rows.
Yes, we can use Worksheet.Change to dermin the change of data on the worksheet then we can modify the formula as we wanted. Here is a sample for your reference:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Me.Range("A1").Formula = "=MAX($A2:$A" & Me.UsedRange.Rows.Count & ")"
Me.Range("B1").Formula = "=MIN($B2:$B" & Me.UsedRange.Rows.Count & ")"
End Sub

Hi Glyn,
Can you create a script that recreates the problem?
I have a similiar problem, but can not recreate the exact operations sequance that cause the ORA-07445.

I need to split my c partition

Hello i have lenovo g580 and i saw in the forums that i cant split the parition cuz it will disable the recovery but in same time the c partiion is 880GB and the other partition contain drivers is 24GB so Please any help

Hi mahmoudahmed,
Thanks for posting and welcome to the Lenovo Community,
Am sorry to confirm to you that splitting the Hard Disk will cause that the recovery will be corrupted and won’t be working anymore,
And the recovery is built-in application to return the machine back to the initial state if you would like to proceed and split the Partition it would be my pleasure to help you.
Thanks and Best Regards,
Soha
