I have used FLASHBACK TABLE option in my oracle 10g database.
It works successfully but the indexes got system generated name after flashback table option.
how i get all the indexes with same name which was before flashback.
one of my user POM create one table using this statement
12:55:59 SQL> create table hello_world (emp_id number(4), emp_name varchar2(30))
;
Table created.
then insert some raw into this hello_world table
12:56:41 SQL> insert into hello_world values (1, 'Bill Gates');
1 row created.
12:57:51 SQL> insert into hello_world values (2, 'Steve Jobs');
1 row created.
13:00:32 SQL> insert into hello_world values (3, 'Chris Eaton');
1 row created.
13:01:19 SQL> commit;
Commit complete.
then i have drop this hello_world table
13:02:08 SQL> drop table hello_world;
Table dropped.;
then i have to connect with sys user
13:03:03 SQL> conn sys as sysdba
Enter password:
13:08:21 SQL> select current_timestamp from dual;

i flashback my this HELLO_WORLD table but why i cannot Flashback RAW of this table .what can i do if i want to flashback raw of this table which query i have to run,
Flashback table operations are not supported for the SYS user . I have found the above line in one of the article.
I don't know why the SYS user can not able to flash back the table.
I delete some of the data from a table unfortunately and make commit on that on my production server.
getting back my all data of this table only of last 15 minutes.
Can I use flashback in application, especially DBMS_FLASHBACK.TRANSACTION_BACKOUT. I import some information (from files) in my database and after that I want to revert that transaction(delete imported data). I did some test I took xid of the transaction from v$transaction and then executed
DBMS_FLASHBACK.TRANSACTION_BACKOUT
with that XID for parameter. Everything is fine but that time there was only one transaction, when there are many transaction how can I get the exact XID. I can use dbms_transaction.local_transaction_id to get information for transaction which is running. And when i tried to use flashback that way a deadlock occur and db killed the other transaction.
I've just found out that 12cR1 will not (in all likelihood) allow "flashback database" for pluggable DBs. Am I the only one disappointed by that ? I use flashback db (+replay) a lot to revert and replay automated tests and I had plans to consolidate tenths of test environments into PDBs.

View 11 Replies View RelatedI'am using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit with the following:
db_flashback_retention_target 1440
undo_management AUTO
undo_retention 900
Is it possible to enable flashback only to some specific tables?
For example, we are only interested in the capability of flashback tables scott.emp and scott.dept, no more.
I fired following commands .
>create table t1(id number);
>create index indx_t1 on t1(id);
>drop table t1;
>flashback table t1 to before drop;
but when i fired
>select index_name , table_name from dba_indexes where table_name='T1';
it shows index name something like "BIN$QvTWVG3dTxmBBJ607f9CWQ==$0" so is their any way to recover that index name
Since tablespaces can be enabled/disbaled for flashback is there a query that can tell me the flashback status of each tablespace in my DB.
View 2 Replies View RelatedI need store history for two tables in my system. I thought that Flashback Data Archive will be the best option. There is also another ways to do this but don't focus on this. I need to to this by FDA (Flashback Data Archive);
So my prerequisite was to create tablespace and flash back archive, and alter table to be archived.
create tablespace audit_archive datafile 'd:oradata etaaudit_archive.ora' size 100M;
create flashback archive audit_flash_archive
tablespace audit_archive quota 10G retention 10 year;
alter table teta_admin.t_prac flashback archive audit_flash_archive;
and everything works fine but on sys user.
i can query this table using "as of timestamp" clause
select prac_id, imie, imie_2, nazwisko, nr_ew from teta_admin.t_prac as of timestamp to_timestamp('2011-08-23 08:20:00','yyyy-mm-dd hh24:mi:ss')
but final construction of idea was to create additional user (interface), grant select on teta_admin.t_prac object and query archive data from interface user. and this is point of my failure. this don't work on new user.
interface user have such sys privs:
SQL> SELECT * FROM dba_sys_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
INTERFACE CREATE SESSION NO
and table privs:
SQL> SELECT * FROM dba_tab_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE
------------------------------ ------------------------------ ------------------------------ ------------------------------ --------------------
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN INSERT
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN DELETE
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN ALTER
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN FLASHBACK
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN SELECT
what i need to do in order to query this flashback table from interface user. when i try to do this from this user oracle says ORA-00942.
what happen in standby when enable flashback in the primary database?

I guess that it maybe like archive log ,it can release the space using RMAN.But when i try a test ,it fail.

I have configured a flash recovery area of 9g yet the system keeps complaining that i have not enough flashback logs?
SPACE_RECLAIMABLE 1103842304
ESTIMATED_FLASHBACK_SIZE 45195264
the space_reclaimable is more than ESTIMATED_FLASHBACK_SIZE, so how is it possible the system always complain not enough space?

I have read it in books that flashback uses undo data to create the flashback data or to flashback the database to a time in the past.Then, what is the role of archive files in flashback operation. Why it is mandatory to turn on archiving before turning on flashback. Also, if you remove the latest archive files, you can NOT flashback the data to a time in past (Oracle complains of missing archive files).

I want to implement Fast-Start Failover at my enviroment. Reading requirements, I found that Oracle Flashback is needed (I don't use Flashback on my databases).
Best Practices recommends 60 min (1 hr) for DB_FLASHBACK_RETENTION_TARGET if I just want to use Flashback to fast-start failover.
My questions:
What 's better, setup up flash recovery area on ASM or O.S. filesystem?
What is the recommended size for flash recovery area?

View 1 Replies View RelatedThe undo_retention is used for read consistency, to avoid snapshot too old.Flashback database is using files in the db_recovery_file_dest.But whether undo_retention has any influence on Flashback drop; Flashback table or Flashback query?Let's say we have set undo_retention = 3600 = 1 hour.And
db_flashback_retention_target = 1440 = 24 hours.
Will it work Flashback drop; Flashback table; Flashback query to get 12 hours back?Additional question. Why Oracle sets undo_retention in seconds and db_flashback_retention_target in minutes?To use the same measure would be more user-friendly to DBAs .
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?

We have to load 10 million rows in a table from another table based on the multiple joins. How much tablespace size we allocate to the table and for performance point of view how much should be the SGA size.
View 11 Replies View RelatedWe have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.
what command is used to create a table by copying the structure of another table including constraints ?
