I was about to move some tables from one table space to another but it seems it is not possible to move partitioned tables between table spaces of different block sizes.
So far the only option I have is to export and then import back the data.
know if there is any way to move a partitioned table between table spaces of different block size?
i want to rename a table that has partitions.
alter table
testora.oldtablename
rename to
testora.newtablename;
ORA-14048: a partition maintenance operation may not be combined with other operations
DDL used to create a table that is partitioned by day, then rolled up to a month using the interval partitioning technique.
View 3 Replies View RelatedI have a partitioned table (one partition per month). Every month there are added about 1GB data. What extent size should I set? 1GB will be ok?
What if data will be greater than 1GB, adding new 1GB extent takes probably a lot of time and clients may see delays while they're inserting in this time? (it's OLTP system)
When new extent is allocated? Exact in time of lacking space in existing extent or before? Partitions are dropped after one year so free space isn't a problem.
While trying partition exchange feature of Oracle with 2 hash partitioned tables, I come to know that I can't directly exchange partitions between 2 partitioned tables
I have two hash partitioned tables , so to move partition data from one table to another will include-
1) Exchange from partitioned table to non-partitioned table.
2) exchange from non-partitioned table to new partitioned table.
But I am not sure in which hash partition my data will go in new partitioned table (data need to be moved has single key value on basis of which tables are partitioned),
that are my biggest tables
Users use front end (called ESS Console) and when they try to open one of those tables they wait very long (really bad performance). Sometimes the GUI even hanging without displaying results.
Does Partitioned Tables feature works for better performance?
I need to find the tablespace size (used and free) for a partitioned table
View 3 Replies View RelatedI have requested the Infrastructure DBA to move a table with size 126GB(as shown in the stats/size tab in TOAD) from one tablespace to another.This is free the huge space in the first tablespace which i wanted to use for creating another table.
But when the table is moved to another tablespace, surprisingly for me, i saw that the sizeof the table has come down to 8 GB from 126 GB.Point to be noted is that everyday there are physical deletes happening on the table.
I have a table: desc STG_XML

MODIFICATION_DATE TIMESTAMP(6)
ARCHIVING_DATE TIMESTAMP(6)
CREATED_BY VARCHAR2(50 CHAR)

The problem is that the data of the table are 40GB while on the DB the table holds 400GB! How can I shrink and reuse that space except from drop/recreate and drop/import?
The table has no initial data, so that I can play with the INITIAL parameter. Data are inserted, updated and deleted all the time. I have run DBMS_ADVISOR which recommended to SHRINK table. I have performed the shrink :
alter table STG_XML shrink space COMPACT;
but I haven't gained any space.
One of our solaris machines is running Oracle 8.0.3
A table reached the 2 Gb size and oracle failed due to the operating system file size limitation.
The information in the table is not relevant and can be deleted, but the table contains a lot of indexes.
I would like to know the best procedure to delete the information and reduce the size of the file.

Ok, the above shows us:
- we have 55 blocks allocated to the table (still)
- 35 blocks are totally empty (above the HWM)
- 19 blocks contains data (the other block is used by the system)
- we have an average of about 2.8k free on each block used.
Therefore, our table
- consumes 19 blocks of storage in total.
- of which 19 blocks * 8k blocksize - 19 block * 2.8k free = 98k is used for our data.
not too sure this calculation is accurate for getting the size (data)of the table.
I am using oracle 10g with sga_max_size =4GB and db block size 16k. Now i am creating a tablespace with block size 32 kb , whats value i select for the parameter db_32k_cache_size.
Is there any standard way to calculate the value of this parameter.
I need to create table A. which will going have more than 8L records. Daily this table A will truncate and reinsert all 8L records. Also number of records(8L) will we increase 50K per month. what should be storage clause parameters . Mainly initial and next extent.

the 2 can have difference block size?
AS of we know that we can get the number of blocks occupied by data in a table by querying the user_tables Data Dictionary.
My questions are,
1.)how to know if i want the each block size ?(i.e each block size either it is 4kb or 8kb or 16kb..)?
2.) Is the block size is same for all blocks in a table and in Database or it varies?
3.)The block size is DB dependent or Table dependent or Machine dependent(32-bit, 64-bit and OS)?
what is the best way to partitioned a non-partitioned table to partitioned table date wise? I have data from last four year?

We are planning to export the table data to a file pipedelimited. How do i estimate the size of the FlatFile based on the table size? or avg rowlength
View 3 Replies View RelatedI am trying to export a partition of a table and import it to another database. I get the below error when I try to import.
ORA-14400: inserted partition key does not map to any partition
If I export the table(for that particular partition) and import the table(after dropping the table) in destination, the partitions and sub partitions are created without any problem.
The table is Range Partitioned and Sub partitioned in List. So I had to perform the below operation if I want to retain other data in the Destination table.
1. Drop the existing partition
2. Create the partition and sub partition, same as source
3. Execute imp
In fact I had to perform step#2, as if I split the partition also, the sub partition gets replicated in the new partition, which again throws the same error. Is there better way of managing the partitions and subpartition in destination with exp/imp utility, so that I need not perform step#1 and step#2 manually.

I am exporting a table that is 3 GB in size and also Partitioned with option NOCOMPRESS specified.
Now when i export it with COMPRESS=N option of exp utility then it should take 3 Gb in target server but will exporting it with COMPRESS=Y will save some storage during import or once NOCOMPRESS option specified on partition has no impact on exp utility COMPRESS=Y option and it will take 3 GB space in both cases
Is this true that whether u specify COMPRESS=N|Y during export it does not matter the size will be 3 GB always after import?
We deleted millions of records from a table.
1.Is it necessary to reorganize a table and index after the deletion of records from table ? Because i see some change in table size after table and index reorganization.
2.Will re org table and index improve the database performance ?
We are working on migrating from 9.2.0.4 to 11.2 and we've set up a test machine so that we could test the install and the import (as well as test additional 11g features that we want to begin using).
So we created the database and created all of the tablespaces beforehand.
Our import command is

However, when we run the import, we get the errors like so:

First of all, the block size in our "newly" created tablespaces is 8192...and these are obviously trying to recreate the tablespaces with a block size of 2048.
1) Why is it not ignoring these create tablespace commands when those tablespaces already exist?
2) how in the world do we get around the block size issue? We've tried nearly everything we could find, but we've still not had any luck.
