ALTER database switch logfile

Hi friends,

Oracle 9i DB

I do a backup of database pending (Hi-brid) and keep updated every hour on the top of the hour sked with the archive logs generated.

I'm just a little confused. If I have 3 log files, and if I command "edit files of newspapers to switch to database", 3 log files
be converted in newspapers of backup archive? or only one of them only and I must issue the order 3 x so that I'll be able to get all the last transaction inside the 3 redo log to be applied to the standby server.

Thank you very much

Mrs. Mina

No it's not really necessary: redo log switch once should be enough if you send the archived standby redo log and apply in standby mode.

Alter system switch logfile

Hi all
9i
RHEL5
We make the standby database as our report server. It comes to unload part of the Production workload to improve performance.
To get the latest data, or before you run reports on the standby server, I'll first > alter system switch logfile;
So that the backup database will be updated the last transactions to date.
How often should I run the command? Is this enough to run it only once? or I'll run it n times according to the number of newspapers of recovery?
Thank you very much.
JC

In 9i to run queries on the standby database, you must open the database in read-only mode standby. In this case there is therefore no question of switching logfile or so. Before opening the database in standby mode ReadOnly, you make sure that all the archiving of primary logs are applied to the standby database in managed recovery mode. Once this Eve is open for requests.

I suggest you read below. It erases the concepts and is specific for 9i

alter system switch logfile crashes

Hi Experts,
Please help me determine the above error.
Recently, I was told to take one of our EBS environment in archivelog mode. While doing this activity, I coped 'ORA-16014.
The steps that I follow are listed below:

Now, the session hangs then I checked my alert log file and found the details below
ARCH: Stopped archiving, error occurred. Will continue to retry
TRCDEV ORACLE instance - error check-in

ORA-00312: wire 2 1 online journal: ' / mnt/DEVdata/trcdev/redo02b.log'
After reading the newspaper to alert carefully, it is clear that it is not able to archive the logs and archiving is hung.
The reason could be my destination Archive got filled, but in my case, my destination archive has a free space of about 24 G.

Please tell me how to troubleshoot further, a quick response will be highly appreciated.

-Thank you

@John

I checked log_archive_dest_2 and it is set to null. And I think it would be better if I leave it in its default state.

@Mustafa

Db_recovery_file_dest is also set to null.

Further, I disabled the archivelog mode and erase all the settings that I did for archiving logs (parameter as log_archive_dest_1 log_archive_format).

I have another session close immediately and started the database in editing mode. After that, I activated all the setting again and activated the archivelog mode for my database.

SQL > alter database open;

Did bounce my DB once again, and then manually change logfiles 2 - 3 times and BOOM everything seems to work fine now. No more no hung sessions and archives are generated too.

A big thanks to everyone in this thread.

Diff between switch logfile and archive current log
Hello
I see that the effect for the two statements are the same
ALTER SYSTEM switch logfile;
=
ALTER SYSTEM archive log current;

is that there is no difference between them?
Thank you
Hello..

ALTER SYSTEM switch logfile;

=
ALTER SYSTEM log current ;> archives

alter system switch logfile--> switches to the following log file, regardless of the mode that the database is in ARCHIVELOG or NOARCHIVELOG mode. If the archivelog mode change system swicth logfile will generate the Archives of the redolog which was changed.

change the current archiving--> oracle here log system passes current related to records and archives as well as all other newspapers not archived. It can be fired only the database that is in ARCHIVELOG mode.

difference between switch logfile and checkpoint
Hi all
What is the difference between
Forcing log switches:
ALTER SYSTEM switch logfile;

and
ALTER SYSTEM checkpoint;

When I use one and don't use the other

Thank you very much
Its similar comparison mangoes with tomatoes. Checkpoint is a number that is used to make sure that everything is in harmony with the other data files, control files. They are used in different places for different reasons.
The newspaper fles, as mentioned by Satish, Siwtching is used when it is necessary to create a log file to archive. The only link between this and the control point is that this event causes also point of control and full control point to arrive.

ALTER database open resetlog with ora-01666: controlfile is in standby
I have a problem after I have restore / recovered a backup of the source.

On the target, restoration/recovery all finished successfully, but change open resetlog of database with the following errors:

ORA-01666.

My steps are:

(1) make a backup as follows on the source (which is a prod before) complete
Configure controlfile autobackup on;
Configure snapshot controlfile name to ' / oracle_backup/rman/snapf.f'
BACKUP OF DATABASE TAG 'FULL '.
(2) CPC backupsets above the target
(3) in rman, set the dbid as the dbid of source, restored the snapf.f and then added the location.
(4) then restore, recover (everything is fine).
(5) when I alter database open resetlogs, it gives me error ora-01666.
(6) change the database open worked, but the PB is now in sleep mode and readonly.

I checked the settings, the dbname points to the dbname in source and db_unique_name point test on the target name. These two parameters have been reset by RMAN Duplicate.

We do not want a standby db, we need a test copied from the sourc.e environment

How should I proceed from here?

Thank you
Hello again;

And there is the problem, the only file of control is a watch. Compare your this example of mine:

Note the version of ".bak" auto backup and y.

I think you need to take another backup. If you use Oracle 11 I have even more options.

For example, I update my test system using this:

http://www.Visi.com/~mseberg/RMAN/diff_database_duplicating.html

Sometimes I save on users, roles etc and replace later to hide.

Subsequently

You may be able to save what you have by creating a trace on the source file and then use it to re-create a control on the copy file.
```
If you run a backup trace command daily you can probably pull some SQL from your daily trace file like this.

CREATE CONTROLFILE REUSE DATABASE "RECOVER2" NORESETLOGS  NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
...
...
```
You can save as say cf.sql, then:
```
SQL> startup nomount 

Run the SQL as shown above

SQL> @cf.sql

Control file created.

SQL>

Check the status of the database

SQL> select status from v$instance;

-- should be mounted

If the database is mounted, can it be opened?

Open the database

SQL> alter database open;

Database altered.
```

Running in noarchive mode - so no backup. This is a new test database.

The database was working fine. I used SQL Developer 'data copy' to bring objects of production database for test. The program ran for hours and never finished. So I clicked on the button "Cancel". And "the copy database" program closed cleanly.

I was able to connect to the database, but when I tried to create a db link it hung. So I made an immediate halt and the database closed properly.

But when I tried to put the database in the rear seat... that's when the problem started.

It seems that you have corrupted objects "bootstrap", such as access$, which is necessary for the open operation. Only solution is to restore from a backup, or re-create DB.

Hello. I was recovering a database today and had a little blip.

What is the problem with the script?

any help in this...

Thank you

You would be able to open the database if you include it in the execution block

C:\Documents and Settings\Administrateur > rman target sys/oracle

Recovery Manager: release 10.2.0.5.0 - Production Fri Jan 13 18:03:40 2012

Copyright (c) 1982, 2007, Oracle. All rights reserved.

connected to target database: PRIM (DBID = 769308260, is not open)

RMAN > run
2 > {}
3 > alter database open;
{4 >}

using the control file of the target instead of recovery catalog database
open database

1.i just want to know why we need to use resetlogs, when I place this order, what happens internally in the oracle?
2. when the new name of the database is updated in all the data file during create controlfile or opening of the database?
3 alter database open resetlogs what happens internally in the oracle when I place the order?

Please me tips

Shan

Physical standby without ALTER DATABASE FORCE LOGGING
Hello
Is it possible to use the physics of the standby database without executing ALTER DATABASE FORCE LOGGING primary side?
Can I use alter tablespace force logginng instead?

I want to have a tablespace with nologging option to reduce the traffic of again for some operations.

I can't verify this because I don't have enough servers to build the configuration of Eve.
```
Were there any changes between 10g and 11g in necessity of doing ALTER DATABASE FORCE LOGGING?
```
I see nothing in the documents, and I put them in place on both versions. In fact, my document Oracle 11 for DG of installation works perfectly in Oracle 10.

I see nothing in the book of Larry to indicate a change.

If you are looking for B14239-05 and E10700-02 "Force Logging.

You will find the exact text even under the exact same section 3.1.1.

This highlights without change.
