S.Azar,
You must be clear about the things that when you read the web notes, there may be an incompatibility of the language. The best is first, that research on the oracle documentation.
Now on your doubt, it is a mismatch of terminology that happens here. To enable Flashback Database that is a copy more persistent undo data, stored separately in an FLB file, you must have configured in your db in archivelog mode. Without this, you cannot enable the Flashback Database feature. And you cannot switch noarchive log mode as well if you have the Flashback Database mode on.
The other thing (that I guess Anurag mention) is the normal function of Flashback that relies on the Undo data stored in the undo tablespace. Only, this is based on the undo data and doesn't depend on the mode of journal archive / nonarchive of the database. But it is limited to these data and this period of time up to which you can store the undo data in your undo tablespace.

Spend my DB no Archive Log Mode 11 g
I have a big database running on release of oracle 11g 2 with a large number of users and huge daily transactions running in archivelog mode, I will change the mode of the database in any mode of journal archive
the following steps: -.
SQL > shutdown immediate
SQL > startup mount
SQL > alter database noarchivelog;
SQL > alter database open;
is there a risk to do
can the database after change in noarchivelog mode, could not be opened?
What are the reserves to take before doing this work?
Thank you very much.Hello
I think that you must not need change size of db recovery file destination.
You must use the parameter log_archive_dest_n with LOCATION, witch's location is your destination to archive.
Log_archive_dest_1 default value is use_db_recovery_file_dest, you must change this value.If you do not need to archive newspapers, then you can remove all the recovery logs archived after backup with RMAN.

Archive log mode in oracle 10g on windows environment
Hi all
I have a data base (Oracle 10 g 10.2.0.1.0) on windows 2003 server. yesterday, I put the database in archivelog mode. When I ask spfile location displayed in the location ORACLE_HOME\dbs.
but when I created pfile using the spfile she is created at the location ORACLE_HOME\database. and there is also an another spfile. I put the log_archive_dest to one location other than flash_recovery_area in pfile, but it is to show the DB_RECOVER_AREA.
today i saw archives created in these two places.
can a database cause two spfiles. and work on them?
can I remove a spfile to /dbs location.
pls give me suggestion to remedy this

Show us the cut and paste the sql prompt, the output display,
show parameter archive show parameter spfile
Under Windows, the database file is the work one, dbs is designed for * nix systems. Then a former will work and is supposed to be used by oracle. Show us the output of the commands above so that we can see exactly what is happening.

Thank you
N ° so that the flashback is enabled on the database, you must have your database works Archivelog mode.

change log mode archive without closing the database
Hi all
Is it possible to put the database in archive log mode before you shut down the database, and when the database stops and starts, the database should automatically be in log mode archive?
because we cannot stop the database in the days of the week and we have system restart the weekend and we are not here this day here. So is there a way to set the database in the log archiving across the memory so that each restart of the database, it should start automatically in log mode archive.
my environment is windows server 2008 R2 with oracle 11.2.0.3
Thanks in advance.

Thanks for the reply Max Seleznev,First of all I thought to write the script to include in this process. But we cannot run all the commands in the sqlplus using windows task. for example:
You can write a batchfile as below:
CD.
sqlplus / as sysdba
Select name, open_mode from v$ database;When you run this, it will open up to sqlplus prompt but then will not run the query.
This is the reason why I am to know if there is another way.
Thank you
When you do things wrong, you do not get the desired results
Please desired SQL in a separate file (run.sql), then proceed as below

A copy of recovery/db + archive logs
Hi champions.
There is a confusion in the recovery of a database. Version 10g.
I have a hot (using the copy command) of a database backup (mode of journal archive) I took to 22.00.00 on Sunday.
Now, my database is up and running Monday, Tuesday, Wednesday in archive log mode. Since the last backup .and (Sunday 10 pm) my database got crashed Wednesday 14.00 completely lost everything (CDR files) archive logs only is with me, I have the newspaper archive...
Can I recover my database using the backup from Sunday + newsletter archive until it crashed.
Kind regards
Shitesh ShuklaIf you have an old backup of the controlfile, you use restore database with backup cotrolfile to cancel. Backup Controlfile as of old, he would keep asking for the archivelogs to provide for backup if you need to cancel the recovery.

Please provide the correct steps
so that the work of database and schema can not lose more after that the archive log is enabled.
Thank you all for your response.

Problem with the archive log when you use RMAN for backup and restore (11g 2)
Hello world
Please help me solve this problem.
I'm just beginner in Oracle Database (11 g 2). Today, I had a problem, I tried to back up and restore my db by RMAN. I delete all the files in /u01/app/oracle/oradata/orcl / * , then I restore them easily, but the point is I have a table, I can restore Hungarian, but cannot restore anything ranks in it (something wrong with step restore database). I'll tell the detail below.
-First, I create a 'Day' with command table create table hr.day (varchar (20)) day. Then I backup complete by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_FULL_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 0 tag 'DB_FULL' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_FULL' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}
D ' other hand, I have insert 'Monday' to table. then do an incremental backup by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_INC_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 1 tag 'DB_INC' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_INC' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}Repeat 7 times (Monday-> Saturday). And I got these files:
[oracle@rac ~]$ ls -l /u01/backup/
total 400280

If i ignore it and open the database, just my table in full backup come back but rows was not restored. I'm sure the problem is my archive log backup but i don't know how to solve it. Plz help me.Sorry for a long post.
> 1 and from the 1205841 SNA sequence
The SCN that indicates Oracle is above the range of SNA that you have in the ArchiveLog backups for sequence 1 to 15 (15 sequence ends at 1205840).
The message
channel ORA_DISK_1: restoring archives Journal
Archives journal thread = 1 sequence = 15
channel ORA_DISK_1: backup/u01/backup/DB_INC_ORCL_20160120_s117_p1 piece reading
channel ORA_DISK_1: piece handle = / u01/backup/DB_INC_ORCL_20160120_s117_p1 tag = ARCL_BKP_INC
indicates that he has restored the sequence up to 15
You can check the log file alert database instance for messages on the fact of recovery.
He is now asking sequence #1 it seems you did a RESETLOGS after sequence #15.
Note: If you have NOT issued a COMMIT after the line is INSERTED in the table 'Day', the recovery of the database will have no * transactions * to retrieve. An uncomitted transaction is cancelled.

Data Guard - RMAN removing archive log
Hello
I ' v DataGuard with physical standby.
I do a backup only on the primaries. Both sites have ther separate backup systems.
I ' v FRA and configured archivelog deletion with RMAN configuration:
on primary: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
standby: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;
It works fine but I think what if scenarios and I'v qestion on best practices for backup after the transition of role management. Let's say that for some reason, as i'v in switch mode sleep for a few days and the backup will be posible to watch (now primary) database. What would be the steps/reconfiguration appropriate to do?
1 should I reconfigure RMAN?
change of new primary to: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
change back to sleep again: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;
2. make full backup
Hello
1. you can refer to the oracle documentation: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmconfb.htm#CHDCFHBG
section: "all archived Redo Log deletion policy."
Document provides the best algorithm to analysis of work
You can use the
CONFIGURE ARCHIVELOG DELETION POLICY BACKED UP
integer
TIMES TO DEVICE TYPE
command to allow a policy of removal of archived newspaper. This configuration specifies that archived newspapers are eligible for deletion only when the specified number of archived log backups exist on the specified device type.If the deletion policy is configured with the
BACKED UP
integer
TIMES
clause, then aBACKUP ARCHIVELOG
, the command copy newspapers, unlessinteger
already exist on the specified device type backups. Ifinteger
are backups of logs, then theBACKUP ARCHIVELOG
command ignores the newspapers. In this way, the deletion of archived newspaper policy works as a defaultNOT BACKED UP
integer
TIMES
clause on theBACKUP ARCHIVELOG
command. Note that you can override the deletion policy by specifying theFORCE
option on theBACKUP
command.The deletion of archived newspaper policy has also options specific to an environment Data Guard. , then RMAN can delete logs after they have been applied to all destinations remote mandatory. If you specify
SHIPPED TO STANDBY
, for example, then RMAN can remove log files when they were transferred to all destinations of mandatory relief.2. the paper provides good information, just to check and decide easily based on the functionality of the database role you can configure.
It will be useful.

There is no data for August 21, 2015, the database is offline for a few days.
The database has been cloned by the system administrator, so nobody was on this database. New server.

That was my thought as well. They have made a copy ' hot' all the files. I think they should have stop the database before copying files.
a ' hot' copy can succeed but each tablespace must have been in online BACKUP before doing the copy of OS files.
With DB mode noarchive, a copy hot may or may not succeed according to the DML activity & duration of the COPY
It's better to STOP NOW before copy of OS

Hello
I am also testing in Data Guard 12.1 configurations.
Oracle support response is "it seems therefore that this information be removed.
So is the best way to check on the database pending:
SQL > select thread #, max(sequence#) ' last day before Seq received. "
v $ archived_log val, v$ database vdb
where val.resetlogs_change # = vdb.resetlogs_change #.
Group thread # order by 1;
SQL > select thread #, max(sequence#) ' last day before Seq applied.
v $ archived_log val, v$ database vdb
where val.resetlogs_change # = vdb.resetlogs_change #.
and val.applied in ('YES', "IN-MEMORY")
Group thread # order by 1;

Hi all
I searched the Oracle and Internet Documents. It is really hard to get information on the management of the archive Log, so I thought to post it here:
Now, our Database 9i (EBS 11.5.x) was in no archive mode, so I allowed him to archive mode.
Edit the pfile $ORACLE_HOME/admin/SID/pfile who will be /oracle/proddb/9.2.0/dbs/initPROD.ora

Question
1. How can I delete old logs archiving without using RMAN?
2. How should I know which Archives connects to keep and delete?
3. is there a way to know why the database generates so many newspapers to check-in?
Hello
Yes, you must keep this archive. You can schedule the job to compress files to archive (record use of space) and move it to another place as a backup.
You can schedule both COLD backup once a week, in this case it is scabies archive for a week.
