• URGENT: Need to flashback table, how to find SNA for quite some time before the update that's happened?

  Hi all

  I have a new database 11G, I haven't used before flashback, but my retention time is a day... I have once the developer did a massive update to a table to corrupt.

  How can I find the RCS for this time so I can try this table of flashback?

  Thank you

  Cayenne

  Thank you.. I also found that it works:

  SQL > select timestamp_to_scn (to_timestamp('20140103152000','YYYYMMDDHH24MISS')) SNA double;

  SNA

  ----------

  98344246

  Although does NOT work all the time. But that's just what Oracle when you give him a timestamp to flashback to: it converts the timestamp of a SNA and then restores the data based on the SNA.

  See table of Flashback in the language SQL doc

  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_9012.htm

  TIMESTAMP CLAUSE

  Specify a value of timestamp corresponding to the point in time to which you want to return to the table. The expr must evaluate to a valid time stamp in the past. The table will flash back to a period of about 3 seconds to the specified timestamp.

  This precision "3 seconds" is because of this conversion to SNA - Oracle uses its internal table.

  YVERT is accurate, if you know, but you typically do not have.

  Read and consider these warnings in app dev guide advanced

  http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28424/adfns_flashback.htm

  Guidelines for Oracle Flashback Query

  • If a potential error of 3 seconds (maximum) is important for Oracle Flashback Query in your application, use a SNA instead of a timestamp. See guidelines on Oracle Flashback technology.

  . . .

  General guidelines for Oracle Flashback Table

  . . .

  • For querying the latest data at a specific time, use a SNA. If you use a timestamp, questioned real time can be up to 3 seconds before the time you specify. Oracle database uses the SNA and assigns them to the timestamps to a granularity of 3 seconds.

  For example, suppose values SNA 1000 and 1005 are mapped on the timestamps 08:41 and 08:46, respectively. A query for a moment between 08:41 and 08:45:59 is mapped to the SCN 1000; an Oracle Flashback Query at 08:46 is mapped to the SNA 1005.

  By reason of this time-to-SNA map, if you specify a time slightly after a DDL (such as a table creation) Oracle database operation can use a SNA which is located just before the DDL operation, causing the error ORA-1466.

• Prerequisite to FLASHBACK TABLE

  Version: 10.2, 11.2
  
  I will say I've accidentally updated a table without specifying the WHERE clause. Can I use FLASHBACK TABLE command to restore it to the former State.
  
  Question1
  I have to run the FLASHBACK TABLE before UNDO_RETENTION period. That is to say. If my UNDO_RETENTION is set to 900 (15 minutes), I have to run the less command FLASHBACK TABLE 15 minutes of the error to the user. Right?
  
  
  Question2
  My current UNDO_RETENTION is 900 and UNDO_TBS size is 2.5 GB. If I want to increase UNDO_RETENTION 7200 (2 hours), I should increase the UNDO_TBS as well. Right? But, how to estimate this?

  Hello

  Question1
  I should execute the FLASHBACK TABLE command before UNDO_RETENTION time expires. ie. If my UNDO_RETENTION is set to 900(15 minutes) , i must execute the FLASHBACK TABLE command withing 15 minutes of the user error. Right?
  

  UNDO_RETENTION initialization parameter must be set to a value that is large enough to cover the period specified in the FLASHBACK TABLE statement.
  doc: http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10739/undo.htm#i1008150

  Question2

  May not be necessary to increase the cancellation SCT size, maybe check and estimate the size of the cancellation of queries undo_stats

  CONSERVATION OPTIMAL UNDO = UNDO FULL SIZE / (DB_BLOCK_SIZE * UNDO_BLOCK_PER_SEC)

  SELECT MAX (undoblks/((end_time-begin_time) * 3600 * 24))

• Flashback table does not work in 10.2?

  I thought that you can cancel a water drop and retrieve any table with FLASHBACK TABLE feature that comes with default 10.2 (i.e. no special set-up is required). But I get this error when I try to do.
  
  ORA-00439: feature not enabled: Flashback Table
  
  I've used FLASHBACK TABLE < table name > before dropping.

• flashback table does not

  Hello
  
  I use oracle 10g R2 on linux X 86. I got reminiscence are the true value. one of my table was accidentally truncated.
  now I want what he back.other tables are reduced thanks to the flashback technology.
  
  but this error that "the definition of table has been changed" I not made any changes to the table definition.
  
  What could be the problem? even if I have backup, but would still like to know and retrieve it using flashback.
  
  return of flame retention objective has been set at 900. and table was droped well before that.
  
  Help, please
  
  Thanks and greetings
  VD

  Well it's okay and it isn't a mistake. Flashback table does NOT work with the DDL changes that you did on your table to Truncate. If you want to return to the table with Flashback, you need to use Flashback Database technology or traditional backup and restore techniques are the only station.

• Flashback Table: Oracle PW

  I find that I restore a table due to the error of the user, to return the data she had this morning - the loss of some data. Oracle 10Gex and then Apex 3.2.1 installation - I didn't know what was the password for database user 'Oracle '.
  
  When the desktop of the server - running the SQLPlus tool - I can connect to the database with SYS (or SYSTEM) DBA - but those ID's have no rights on the schema - at least I can't see the tables in the schema PRD/tablespace. Yes - during the installation, I created a specific tablespace of the user for the applications and it's data.
  
  I think that the 'oracle' user is that I need to connect to SQLPlus with to run the commands in flashback the table... but I could be wrong.
  
  What are your suggestions?
  
  Help!

  Rich,

  Sorry, I don't know what give advised based flashback.
  Don't want to give the wrong information.

  Ask this question in the forums of database - general or SQL and PL/SQL .
  These forums are very active - in half an hour, you will know everything

• Doubt of external Table

  Hi Master,

  Using Sql * Loader I can load the dat/csv/txt data to oracle tables. I can use it when clause contained in the data file and load control in different tables.

• 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 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

  select t.*
    from t@to_inlabnew t, t1
   where t.object_id = t1.object_id
     and t.object_type = 'TABLE'
  
  call     count       cpu    elapsed       disk      query    current        rows

• Table of Flashback and the movement of the line!

  Hello Experts,

  I have a doubt in the next box.

  Movement of the line must be activated for all tables to be able to use the Flashback table feature unless you are flashing back the table TO BEFORE DROP . According to my understanding, you can not enable Row movement for a table that is not partitioned. This finish not FLASHBACK table with activated line movement, you can and you can't activate a movement row for a table that is not partitioned.  So, how can I use FLASHBACK table to NOT partitioned table function?

  Please see the error message when I tried to enable ROW movement for a non-partitioned table below.

  SQL error: ORA-14066: illegal option for a not partitioned index organized table

  14066 00000 - "illegal option for a table held in index unpartitioned.

  * Cause: An attempt was made to issue a CREATE or ALTER TABLE

  command on an unpartitioned ITO, but the order contains a

  option that is legal only for partitioned tables organized by index.

  These options are: ENABLE ROW MOVEMENT and DISABLE ROW.

  Thank you

  No - your question is about FLASHBACK and IOT.

  So, how can I use FLASHBACK table to NOT partitioned table function?

  I have already posted the link to doc as telss you that you cannot enable row movement for a not partitioned IOT.

  View sample data for this table (in the form of INSERT statements) and queries, DML and FLASHBACK that you try to use this table that is a failure.

  Hello
  
  I have the following problem.
  
  I accidentally dropped a column containing the data of a table and to restore the state table, it was before I did.
  
  I found a reference on the internet which States that you can use flashback to retrieve a table to a set in the past point, even if you deleted a column.
  

  Flashback Table
  
  Just as the flashback query helps to retrieve rows of a table, FLASHBACK TABLE helps to restore the state of a table to a certain point in time - even if a table structure change has occurred since then. The following simple command will take us to the table state at the specified timestamp:
  
  SQL> FLASHBACK TABLE Employee TO 
             TIMESTAMP ('13-SEP-06 8:50:58','DD-MON-YY HH24: MI: SS');
  
  Reference - http://www.orafaq.com/node/872

  My DBA has sent me the following information;
  

  Oracle Metalink note  
  
  Limitations and Restrictions on Flashback Table :
  
  Flashback Table operations are not valid for the following type objects: tables that are part of a cluster, materialized views, Advanced Queuing (AQ) tables, static data dictionary tables, system tables, remote tables, object tables, nested tables, or individual table partitions or subpartitions.
  
  The following DDL operations change the structure of a table, so that you cannot subsequently use the TO SCN or TO TIMESTAMP clause to flash the table back to a time preceding the operation: upgrading, moving, or truncating a table; adding a constraint to a table, adding a table to a cluster; modifying or dropping a column; adding, dropping, merging, splitting, coalescing, or truncating a partition or subpartition (with the exception of adding a range partition).
  
  You cannot rollback a FLASHBACK TABLE statement. However, you can issue another FLASHBACK TABLE statement and specify a time just prior to the current time. Therefore, it is advisable to record the current SCN before issuing a FLASHBACK TABLE clause.

  Then my return of flame using DBA in this situation or not?

  I found that it is quite reliable. But when ANY site talking about a newly introduced feature, it must trigger at least one indicator "attention". There may be so many variables affecting the functioning of a new feature or is used unless you see a working example, you must create your own test case.

  As I said some things, like your question above, can be easily verified, so there is no reason to rely on any document to see if it works.

  Is anyway to cancel this kind of thing or it is unrecoverable?

  Almost nothing is "sunk", if you have the right type of backup. For a deleted column, you have an export of the table before the fall.

  Recommended for small changes DDL (for example related to an incremental update) is to take an export of the affected table.

• Deleted lines flashback: unable to read data - table definition has changed

  Hi all
  
  Its really Important.
  
  I unfortunately truncated a table using
  Trancate table mytable;
  
  and made an alter table to reduce the length of the pricision data.
  
  But I need back data of tabla
  
  I used the command to get the deleted lines, below, it shows error.
  
  query: select * from pol_tot versions between timestamp systimestamp-1 and systimestamp;
  error: ORA-01466: unable to read data - table definition has changed
  
  query: flashback table pol_tot to timestamp systimestamp - interval '45' minutes;
  error: ORA-01466: unable to read data - table definition has changed
  
  Well want to share your ideas how can I deleted thoose Records.
  
  Edited by: 887268 July 8, 2012 12:26

  This

  and Made a alter table to decrease data pricision length.
  

  is the cause of your error.

  Now please do what is obvious.
