Oracle's Flashback Technolgy

Hi,
Can any one kindly explain how the Oracle's Flashback Technology works? I mean OFT depends on Automatic Undo Managemet but how exactly it works? Whats the architecture?
Any good link or book name that explains the OFT in detail will be very helpfull.
Actually this was a Interview Question which i failed to answer. I just said that its dependent on Automatic Undo Management.. but they needed a more detailed answer.
Kindly explain.
Thanks in Advance.
SID

A lot of times, what is asked in the interview and what is expected by the interviewer, these are far away from what is there. If someone failed you saying that undo is used for Flashback, I would actually have asked what else he/she wants to know beyond this? And I won't suggest that you should spend time and energy thinking that you knwo somewhat lesser just because some one said to you that he is not happy from your answer. You should have asked what's the answer he is looking for then?
In 10g, except for Flashback database, rest of the entire stuff is based on the Undo data only. That's it! In 11g, there are changes to this but that needs to be told that the person who is asking is willing to know about 11g's enhancements.

Oracle 10gR2 Flashback Size

Hi,
I have following configured for flashback -
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
*.db_recovery_file_dest_size = 4G
I have 3 Oracle Instances running and so, with the same above mentioned parameters, I guess, Oracle created the folders as { I believe Oracle adds $ORACLE_SID folder under flash_recovery_area } -
/u01/app/oracle/flash_recovery_area/DBPROD1
/u01/app/oracle/flash_recovery_area/DBPROD2
/u01/app/oracle/flash_recovery_area/DBTEST
This is not a problem. I was under impression that each of these folder will have 4GB limit for storing the flashback logs. But, looks like that is not the case. One of my database's (DBTEST) flash area was full and then the other two databases started throwing ORA-19815 error in the alert log file. This means Oracle instance doesn't look at it's own area to determine the size of flashback usage? How do we fix this? Just changing the db_recovery_file_dest parameter to '/u01/app/oracle/flash_recovery_area/<database_name>' will solve the issue?
Please reply.
Thanks

As matter of fact Oracle allow such setup
Sharing a Flash Recovery Area Among Multiple Databases
Mutliple database can have the same value for DB_RECOVERY_FILE_DEST, if one of the following conditions is met:
No two databases for which DB_UNIQUE_NAME is specified have the same value for DB_UNIQUE_NAME.
For those databases where no DB_UNIQUE_NAME is provided, no two databases have the same value for DB_NAME.
When databases share a single flash recovery area in this fashion, the file system or ASM disk group holding the flash recovery area should be large enough to hold all of the recovery files for all of the databases. Add all the values for DB_RECOVERY_FILE_DEST_SIZE for the different databases, and then allow for any overhead such as mirroring or compression in allocating actual disk space, as described in "Flash Recovery Area Size: DB_RECOVERY_FILE_DEST_SIZE".

Oracle 10g Flashback

Hi experts,
We have tried to flashback the data from oracle 10g database. for this we have executed AS OF TIMESTAMP query, the Undo has been set 900 and db_flashback_retention_target also 1440 but we can get 4 days old data with help of 'AS OF TIMESTAMP" query, Can you please clarify is there any internal table is for maintaing the old data since undo retention value also very small archive log file also deleted every 4 hours once , then how its possible to get the 4 days old data, where the old data actually stored? Please help on this.

Your old data is stored in UNDO segments. In order to flash back as of timestamp (4 days prior), you must set UNDO retention to 4 days or higher (900 Seconds is default). You must also ensure your UNDO tablespace is sized large enough to hold all data to satisfy retention.
You will not be able to perform flashback on the table if there were any DDL's executed on the table and structure of table is changed since 4 days..
Thanks

How To Deploy Application In Oracle Application Server

Hi All,
We have devloped an application in whic we have used tomcat server .
Now we want to deploy that application in Oracle application server.
technolgy used: J2ee
: Shark work flowserver
database:Oracle(XE)
Platform: windows XP
IDE:Eclipse (ganymede)
Web server:tomcat(6.0)
Thnaks and regards,

I think you put the questionin the wrong forum, this is all about Oracle SOA Technology, and deployment is a task within SOA.
I have created a deployment guide/tool for Oracle SOA products (see my blog, includes java deployment).

Flashback queries

Does the flashback queries work incase of truncate command. As per the oracle documents, you can revert back the prior state using oracle's flashback query based on timestamp or SCN.
This is acceptableand agreed upong DML operations. But want to check if the same concepts works incase of 'TRUNCATE' command.
Anyone ideas/ suggestions from experts are wc.
Chers........ Bob

But want to check if the same concepts works incase of 'TRUNCATE' commandWhy not to check then ?

I drop the old synonym and re-create it but still it gives the same error...

Since you are on 10g did you try flashback table feature - http://tonguc.wordpress.com/2007/01/01/oracle-10g-flashback-versions-query-drop-table-and-recyclebin-management/
FLASHBACK TABLE <tabname> TO BEFORE DROP;
If you didnt use purge option, the dropped object is on your recyclebin - http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_9018.htm#sthref9593

Problem when exporting and importing project from odi 10g to odi 11g

Hi,
I want to migrate my project from odi 10g to odi 11g.
But when i am importing the interface then it is giving the error of mising references .
I have exported the project(without its child component),models
(including my datastore),KM's,folder (without its child component),packages(with child components),interaces(with child components),procedures(with child components),variables from odi 10g.
After exporting all these objects i imported all the objects with import type set as "Synonym mode insert" into odi 11g but when i imported the interface it is giving the error of missing references.
Source technolgy is Oracle and target technolgy is Postgres.
Topologies have been made in the ODI 11g same as in ODI 10g.
Please help.

You dont need to migrate the complete repository. You can migrate a project at a time into ODI 11.1.1.5.x
You have to be careful while importing. You have to follow a sequence when importing.
Empty Project -> KMs -> Models (with DB Stores) -> Variable -> Empty Folders -> Interfaces -> Procedures -> Packages ---- All in SYNONYM mode insert (no exceptions)
And your repository id in 11g MUST be different from the one in 10g.

How to get back deleted data logically

Hi
Friends
Once again need your guidance to solve my this problem.
If I have deleted data and commited.Now I want to bring that data back.
How m I to do this.I want to do it logically.
Pls help me.Is there any thirdparty software to do it logically if yes thwn what its name
Hope to hear soon
Regrds,

There are number of ways to recover from such user erros:
1). RMAN incomplete recovery, if you have proper backups and redo logs to recover until the time just before the user error happened.
http://www.kods.net/use-rman-based-incomplete-recovery-time/
2). Flash back query, if UNDO is being managed properly.
http://www.orafaq.com/node/50
3). Flashback database if set to ON and flashback logs are being written.
http://www.oracle-base.com/articles/10g/Flashback10g.php#flashback_database
4). Last but not the least, Oracle LogMiner, required minimal setup i.e. db should be in Archive Log Mode.
For Oracle 10g:

For Oracle 11g:

Searching time of insertion of a row in a table

Hi all ,
My problem is the following.
I would want to know if it there's a way , under TOAD or SQL*Plus, to have the time when a row has been inserted in an Oracle table.
Thank you very much.

Hi,
If you know the time, for example you want to know the data about one hour back (based on the flashback setting)
you can get from flashback pseudo columns (ORACLE 10g)
Flashback Version Query
VERSIONS_XID - The transaction id that created this version of the row
VERSIONS_OPERATION - The action that created this version of the row (such as delete, insert, and update)
VERSIONS_STARTSCN - The SCN in which this row version first occurred
VERSIONS_ENDSCN - The SCN in which this row version was changed.
Exmaple :-
select versions_starttime, versions_endtime, versions_xid, versions_operation, Dept from Dept versions between timestamp minvalue and maxvalue
order by VERSIONS_STARTTIME
will return something like :
VERSIONS_STARTTIME VERSIONS_ENDTIME VERSIONS_XID V Dept
01-DEC-03 03.57.12 PM 01-DEC-03 03.57.30 PM 0002002800000C61 I 10
01-DEC-03 03.57.30 PM 01-DEC-03 03.57.39 PM 000A000A00000029 U 11
01-DEC-03 03.57.39 PM 01-DEC-03 03.57.55 PM 000A000B00000029 U 12
10, 11 and 12 is actual data
Further id youwant to generat an undo for that...
SQL>SELECT UNDO_SQL FROM FLASHBACK_TRANSACTION_QUERY
WHERE XID = '000A000A00000029';
- output : update "SCOTT"."Dept" set "Dept" = '12' where ROWID = 'AAAMicAAEAAAAA/AAA';
Else you can Add a Column to the Table for Tracing the results about the your data like
Custom Method
Created by
Created Date

How to create rollback statements automatically

Hi People
I need to write a script which can generate the ROLLBACK statements for the IMPLEMENTATIONS(Create table, view, index, package, trigger etc Insert table, update table, delete table, Grant etc - which means that implementation could be anything) .
Is there is anyway that I can create or generate corresponding ROLLBACK statements for each statement that i exceute on my database?
Basically there could be a list of operations that I will do and later on I would like to bring the database back to where it was prior to the implementation.

Welcome to the forum!
Whenever you post provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).

You could use Oracle's FLASHBACK DATABASE funtionality. See Using Flashback Database and Restore Points in the backup and recovery doc
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/flashdb.htm
Chapter 16 of that doc shows how to do it - Performing Flashback and Database Point-In-Time Recovery

Expdp seems to be inconsistent with multiple on delete cascade foreign keys

Hi,
I've raised an SR for this with Oracle already and am waiting for a reply but in the mean time i was hoping someone could give me a hint about something we're doing that is obviously wrong or if anyone else is aware of similar issues. The steps we are following are these:
1) 10.2.0.4.0 source system on SLES10 - we are doing a full schema level export using
FLASHBACK_TIME="to_timestamp(to_char(sysdate, 'YYYY-MM-DD HH24:MI:SS'), 'YYYY-MM-DD HH24:MI:SS')"
This should guarantee us a consistent export of the schema at the closest SCN to that timestamp
We get no errors during the export
2) we copy that file to a destination box which is 11.2.0.3.1 on SLES10
3) we import that file - all the table data loads fine and the row counts are the same as those in the export log.
4) when datapump reached the FK constraints 6 of them woouldn't enable with 'parent keys not found'
The 6 FK's in question are all on delete cascade references back to the same parent table, there are a further 3 child tables which also reference back to the same parent table (all on the same parent PK single column) which do enable OK. The parent rows are indeed not there. In live those rows no longer exist. It appears as if the extract has been don ehalf way between the parent being deleted and the children then being deleted - but i didn't think this would be possible with a 'consistent' datapump export?
So my question is how is this possible?
All i can think is:
a) the tables are being extracted a slightly different scn's due to some datapump bug?
b) on delete cascade actions are somehow in a different scn to the initial delete from the parent table (seems unlikely)
Can anyone shed any light on this?
Regards,
Harry

Is it possible to get the updated table records based on date & time.

Is it possible to get the updated table records based on date & time in oracle.
Thanks in advance.

no, actually i am asking update records using 'UPDATE
or DELETE' statement, but not insert statement.
Is it possible?
I think we can do using trigger on table, but problem
is if i am having 20 tables means i have to write 20
trigger. i don't want like this.Of course it's still possible, typically you'll find applications with a column LAST_UPDATE, probably a LAST_UPDATED_BY and so on column. You don't say what your business need is, if you just want a one of query of updates to particular records and have a recent version of Oracle, then flashback query may well help, if you want to record update timestamps you either have to modify the table, or write some code to store your updates in an audit table somewhere.

ORA-00980 Synonym Translation Error caused by WebUtil?

I have setup WebUtil and applied some CLIENT_TEXT_IO code to a form. Everything worked perfectly running through 9iDS so I configured 9iAS to do the same.
When running the form through 9iAS I am getting the ORA-00980 error about synonym translation. The same database instance was used so so webutil_db shouldn't be the problem but I cannot see how this error could be related to WebUtil - anyone have any ideas.
The CLIENT_TEXT_IO code still works even though this error is reported.

Since you are on 10g did you try flashback table feature - http://tonguc.wordpress.com/2007/01/01/oracle-10g-flashback-versions-query-drop-table-and-recyclebin-management/
FLASHBACK TABLE <tabname> TO BEFORE DROP;
If you didnt use purge option, the dropped object is on your recyclebin - http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_9018.htm#sthref9593
