Server Administration :: How To Check A Partition Have Been Compressed
Oct 20, 2011
How can i check a partition whether it has been compressed? just as flowing test,i can not get the information about partition P_L1 whether been compressed.
SQL> Select
2 aa.compression,
3 aa.partition_name
4 From dba_tab_partitions aa
5 Where aa.table_name = 'TB_HXL_LIST';
create table tb_hxl_user_rh ( statedate number(8), provcode number not null, usernumber varchar2(13) not Null ) partition by range (statedate) ( partition HXL_USER_20110516 values less than (to_number(to_char(TO_DATE('2011-05-17 00:00:00', 'YYYY-MM-DD HH24:MI:SS'),'YYYYMMDD'))) );
ORA-14019: partition bound element must be one of: string, datetime or interval literal, number, or MAXVALUE
quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.
Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.
orcl> orcl> set lin 80 orcl> select KSPPSTVL from x$ksppcv join x$ksppi using (indx) where ksppinm='_serial_direct_read'; KSPPSTVL -------------------------------------------------------------------------------- auto
orcl> orcl> alter system set "_serial_direct_read"=rubbish; alter system set "_serial_direct_read"=rubbish * ERROR at line 1: ORA-00096: invalid value RUBBISH for parameter _serial_direct_read, must be from among false, true, never, auto, always
Actually in our environment , sysadmins are upgrading java versions on Unix (HP & Solaris) Machines and they have asked the query whether oracle database uses Java or not?
If it uses then all the databases need to be shut down for their planned activities and if not no need to shutdown the databases.
i want to create tablespace in raw partion on windows.I have added a hard disk and added extended partition to it. Then created 4 logical partitions of 256 MB with diskpart.exe.I have assigned a drive letter to one of them as X:
However, I am having trouble in creating tablespace on it. I referred to [URL]... I get following error,

If I am not using data of many partitions in any way, will it affect my performance if I am firing select query that uses other/active partitions data.
How can I check when that partitioned was last accessed, also can I brought those inactive partitions offlie? If we can, what will be the advantages or disadvantages of that?
I am not able to exchange partition by following below steps:
drop table manu_tst_hashed_tbl_org; drop table manu_tst_hashed_tbl_bkp; drop table manu_tst_smpl_tbl; CREATE TABLE manu_tst_hashed_tbl_org
[code]...
and getting the below erro:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION 14097. 00000 - "column type or size mismatch in ALTER TABLE EXCHANGE PARTITION" *Cause: The corresponding columns in the tables specified in the ALTER TABLE EXCHANGE PARTITION are of different type or size *Action: Ensure that the two tables have the same number of columns with the same type and size.
I have one user CD_APP. I have one partition table CD.T_FCDR_DT. User has got ALTER/INSERT/UPDATE/DELETE/SELECT privileges on the table..
Now when I try to drop a partition, I get error as below: ------------------------------------- SQL> show user USER is "CD_APP" SQL> ALTER TABLE CD.T_FCDR_DT DROP PARTITION D01 UPDATE GLOBAL INDEXES; ALTER TABLE CD.T_FCDR_DT DROP PARTITION D01 UPDATE GLOBAL INDEXES * ERROR at line 1: ORA-01031: insufficient privileges -------------------------------------- Do I have to grant some other privileges for this user.
I need to display the parameter and status of DB for listener and Read Only.
I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.
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),
The table tb_hxl_hash have two partitions,when i exchange the second partition,it raise error,why?
SQL> Alter Table tb_hxl_hash 2 Exchange Partition P_HS1 With Table tb_hxl_test;
Table altered.
SQL> Alter Table tb_hxl_hash 2 Exchange Partition P_HS2 With Table tb_hxl_test; Exchange Partition P_HS2 With Table tb_hxl_test * ERROR at line 2:ORA-14099: all rows in table do not qualify for specified partition
