• 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
  My current UNDO_RETENTION is 900 and UNDO_TBS size is 2.5 gb. If i want to increase UNDO_RETENTION to 7200 (2 hours), i should increase the UNDO_TBS as well. Right ? But , how will i estimate this ?
  

  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))
  'UNDO_BLOCK_PER_SEC '.

• 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.

• What is better/more quick method to create a table (Oracle 11 g 2 dB)?

  Assuming that there are no statistics for the source tables - tables are deleted and recreated every day

  My paintings have a few million lines

  I'm trying to create a filled with data as quickly as possible via

  1 createtable_name as SELECT * from emp;

  2. create table_name

  Parallel degree 4

  in SELECT * from EMP ;

  
  

  I have 1 case I had some time 34 Sec

  In case 2, the table was created in 15 Sec

  
  

  In oracle other possibilities to create a much faster with this DEC?

  
  

  Or it will be faster when I create a table using create table_name

  (

  column1datatype [NULL |] NOT NULL],

  column2datatype [NULL |] NOT NULL],

  ...

  column_ndatatype [NULL |] NOT NULL]

  );

  or maybe I should use this method

  INSERT /*+ APPEND */ INTO empSELECT * FROM all_objects; 
  INSERT /*+ APPEND_VALUES */ INTO emp SELECT * FROM all_objects; 
  

  or it is better to simply creating a table

  and to use the FORALL in BULK IN THE COLLECTION instruction

  combination of Pentecost of the

  INSERT / * + APPEND * / INTO emp;

  
  

  I encourage you to test different options - as you did for the first two variants: personally, I think that it is much easier to remember these things if I did the tests myself - instead of trusting in the results of others. IE I don't think that there is something more fast parallelized ETG (perhaps with a clause (*)) additional nologging by using path direct inserts (although that INSERT APPEND select should do the same). I expect the operations in PL/SQL block to be slower.

  (*), but you should consider the consequences of NOLOGGING for your backup strategies + recovery

  I checked 11i and R12 versions of our Tables to EBS, but both contain primary keys.

  Is this normal or just tell set primary keys?

  Please notify.

  Thank you!

  PS.* I'm trying to settle our scripts and he is still running a full table scan, because it doesn't have a primary key.

  Hello

  This is the standard installation done by oracle at time of installation of EBS in your organization therefore does not necessarily create a new primary key or an index

  on the table.

  The key primary is a combination of unique key constraint not null, and if you look at the script or the definition of the table, you will get the already

  Ed configuration not null not forced and a unique index on some of the columns required by oracle.

• External table Oracle via the Tables API

  Hello world

  I did experiment with the Oracle NoSQL database recently and I became a bit stuck with the new API of Tables. I have so far successfully of the external tables on the data entered using storage techniques 'vanilla' KV and avro (using generic and specific links) scheme, but create API Tables seems to be another matter entirely.

  My question arises in the trainer interface, which has a KeyValueVersion and a KVStore. I can't translate a KeyValueVersion created with the API of Tables in a primary key for recovery (since I don't know what the key generated by the API actually looks like to!) or map it on an avro scheme. The problem seems to be that the Tables API writes data in some format that can be easily translated into a string or an integer (releases from external table lines due to unknown characters if I am trying to retrieve all the values in the database to see what it looks like to), and try to map it to an AVRO map results in the error message 'the data are not as AVRO'.

  Scenario:

  I created a very simple table in the administration tool KV, which consists of a column personId (integer) that is PK, firstName, lastName, emailAddr (all channels) and enter 5 rows with success. What I want to do is to create an external table called person that returns just those 5 values (and brand new I add to the table of course). This means that I have to first understand what the parentKey value must be defined in the .dat file and how to take this key and it becomes a primary key for the recovery of the line.

  Faithful old Google could not find information on how to do this (he was only a thread similar to this with the answer "we'll add it soon"), so I hope that someone here managed to do!

  Thank you

  Richard

  Hi Richard

  I understand the issue you are facing. In the current version (12.1.3.0.9) the external tables feature only works with records of K/V not with the Table model, however, in the next version (which us will very soon be GA) we will support integration of external tables with the data of Table model as well. Please make sure that you have signed up for the announcement of release so that we can inform you of the release. I apologize for the inconvenience, he did to you.
