Arc1: 19504 error creating archive log file... after the NFS configuration

I use an Oracle 11.2.0.3 on RHEL 5.7 (no ASM or RAC) database

Why archive log file size constantly change?
I have a question related to the size of the archive log file:
I constantly receive a different size to the size of the log file archive, of course, they are smaller than to the size of the log file.
A guru can explain to me: what possible reason could be?
Thanks in advance!
It can happen due to several reasons:

When you perform a manual archive (via ALTER SYSTEM ARCHIVE LOG CURRENT/ALL)
When Oracle must respect your ARCHIVE_LAG_TARGET (defined in seconds)

Unless you do a manual check-in, your parameter ARCHIVE_LAG_TARGET is the reason why you see Archives of logs with different sizes as Oracle has archived the redo log as soon as the time ARCHIVE_LAG_TARGET is reached. Even if the redo log is not full, Oracle will always have to archive the redo log.

difference between online redolog files and archived log files
What is the fundamental difference between archived log files and online redo log files? .. .plz keep things simple as m a newbie
Online redo log:

Redo online Oracle log files are filled with records of restoration by progression. A record of remake, also called entrance to roll forward, is composed of a group of agents of change, each of which is a description of a change to a single block in the database. Each instance of an Oracle database has an associated online redo log to protect data in case of failure of the instance.

See here,
http://download.Oracle.com/docs/CD/B10500_01/server.920/a96521/onlineredo.htm

Archived redo log:

Oracle Database allows you to save files to one or more destinations offline newspapers filled with repeat groups, known collectively as the archived redo log. An archived redo log file is a copy of one of the members of a group of redo log filled.

See here,
http://download.Oracle.com/docs/CD/B19306_01/server.102/b14231/archredo.htm

Thank you

Redo archive log file extension
Version: 11 g
OPERATING SYSTEM: AIX 5.3

After you have enabled archiving, I noticed that archives logs files have the extension * .dbf. Is this normal?
close the database and putting into service again.

Then, check the setting.

Removal of the Archive Log files
Hello

I put my test DB to archive log mode and it generated 10 GB of archivelog files and the server ran out of space!
So I reset the newspapers, the DB value no. Archive Log and deleted the files from the server through the shell.

However,.
If I select * from v$ archived_log
Oracle, DBMS thinks that the files are still there.

Where can I remove these filed from the RDBMS?

Hi all
I have a question, the issue is that log file Archives consist only validated data, or it can contain a data.thanks uncommitted to the answer in advance.

Your question is answered, so clerks of the newspapers contain archives and data constantly. Simple example, if you run long DML statement like update in running or insert in this case all by running this transaction you can get more than archivelogs always the transaction is not completed, but will generate the archivelogs.

Recovery of database of old backup and archive log file complete
Hi expert Oracle!
I encountered the problem where my oracle database restore.

In my case:
-My version of the database: 10.2.0.2
-J' have a full database backup (01 - Nov)
-J' have all the archived since (01 - Nov-> 05 - Nov) log file
-My database down to 05 - Nov with disk error (no data file, not again...).
-I have no backup RMAN (01 - Nov-> 05 - Nov)

How to restore my database to 05 - Nov?

Thank you
After you RESTORE the DATABASE,

Use the VALUE UNTIL to set the Point of recovery to 05 - Nov, and then RECOVER the DATABASE
OR
Use the SQL command "RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL" that will keep asking 'future' ArchiveLogs backup.

Real - Time apply a few times using archived log file
Hi all

I have a doubt about the real time apply in Oracle 10g 10.2.0.4 version where the arch process has been configured on the primary and standby has been configured for maximum performance with real time mode applies.

But in the alert log file shall I use to find the message below rarely
```
Media Recovery Log /oraclearch/oraarch/ctdr/5548.dbf
Media Recovery Log /oraclearch/oraarch/ctdr/5549.dbf
```
So my question is why the archived files are applied pending have been configured for real-time if applies where it should apply only from logs in mode standby online.

Also I can't find any information on the eve of the database in the view v$ standby_log that these pending online log files have been archived in the column archived, then how to find how much data was written by process Srl rfs...

-Yasser
Hello

The server process (RFS) remote file writes data to redo in files newspapers awaiting restoration by increase the standby database, application services log can recover again waiting for redo log files, as they are filled.

Archive log file bloat - is currently out of cold back to the top of the best strategy?
Hi friends,

I have a database 10 g. / WinSvr2003 making heavy spatial processing of the Oracle.

Previously, I ran the database in log mode archive and sparked a lot of files to archive log. 150 G (the worst week).

I got fed up with backups (incremental) RMAN night heavy and put the database in a mode non - archive journal. (I was also worried about the time to get the data back out of band).

Now, I come to launch the next nightly bat file: -.

oradim-stop-sid DEV - syspwd *.

del /S /Q D:\oracleBackup\DEV\*

XCopy/e D:\oracle\product\10.2.0\oradata\DEV D:\oracleBackup\DEV

oradim-startup-sid DEV - syspwd *.

----------------------------------------------------------------------------------------------------------

1 week ago - when I arrived-in the morning the database had not restarted due to an inconsistency of data file.
Recover the database fixed.

I guess he had something that this necessary in the redo log files? (its mode no - archive).

I have a DB 24/7.

This cold offline backup is the best strategy to avoid the bloat of log file archive

I can always use RMAN and do not back up files of newspaper Archives? How can I make sure that it is a consistent RMAN backup if she has no access to archive the log files. (I just use RMAN after an immediate stop - restart?)

How instruct you RMAN is not to get the files to archive log?

DATABASE INCREMENTAL LEVEL 0 BACKUP; <-this leaves archive the log file out of the backup.

Thanks in advance.

See you soon,.

AA

P.S. This is my first post on this forum. Yes!
If you
a. make a backup of the database CONSISTENT (that is to say in MOUNT but not OPEN) with RMAN
b. do not save the ArchiveLogs
c. yet the ArchiveLogs to create the database in ARCHIVELOG mode,

You can still use the combination of consistent backup and ArchiveLogs generated since the backup database (assuming that the ArchiveLogs are still on the disk) in the method of 'Refresh '.

In other words, RESTORE (but not RETRIEVE and OPEN) the database of the RMAN.
Using sql RESTORE DATABASE with the HELP of BACKUP CONTROLFILE to 'Updating' then apply ArchiveLogs for what is just restored.

Removal of log file archive on the backup database
Hi all

This command delete CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY archive log file automatically on the basis of data pending?

Thank you
Hello

There are two areas... (1) primary 2 pending)

I thought that you have set this parameter on primary... So like I said if set you in primary this custom delete archive logs in the standby mode.

But if you choose standby, Yes it will be erased.

More evidence - based Archivelogs maintenance ensures [464668.1 ID]

Hello

Can you please let us know why you want to delete the log file archive?

BTW, you can use RMAN to achieve by archiving log backup and delete the original file using the following command:
```
Backup archivelog all delete input;
```

Size of the log file Archive
Redlogfile size is 16 MB and generating the archivelog file size is approximately 10 Mb. what could be the reason?

First of all:

a redo log contains a lot of things necessary for instance etc. recovery an archived log is used only for the restorations - he didn't need all the stuff that is in a redo log, so when written CRA the archiving log that he does not write all knowledge, all that is required for restores

Second:

Archive logs is created with dimensions smaller, irregular, as the original redo logs. Why? [388627.1 ID]

Information in this document applies to any platform.

Goal
Archive logs is created with dimensions smaller, irregular, as the original redo logs.
Commands like:
ALTER SYSTEM SWITCH LOGFILE
or
ALTER SYSTEM ARCHIVE LOG...
are not used to generate archives or change the log file. Thus, there is no parameter ARCHIVE_LAG_TARGET set.
What else could cause this behaviour?
Solution
From:
Bug: 5450861: NEWSPAPERS ARCHIVE IS GENERATED with one SIZE SMALLER THAN THE REDO LOG FILES
the explanation of this situation has 2 main reasons:
1 archiving logs do not have to be in the same size. This was decided very long ago, when blank padding archiving logs stopped for a very good reason - in order to save disk space.

2. the log command does not exist when a redo log file is 100% full. There is an internal algorithm that determines when to switch journal. It also has a very good reason - do the command of newspaper at the last moment may incur performance problems (for various reasons, outside the scope of this note).
So, after that newspaper ordering occurs the archivers are only copying the information from the redo log files. As recovery logs are not 100% full after the command to log and archive logs are empty not filled after the copy operation is complete, this results in unequal files smaller than the original of redo log files.
This is very apparent for very low (less than 10 MB) log files; as a result, produced 2.5 MB archive logs of 5 MB recovery logs are very visible.
Just note that currently, the default log files are 100 MB in size. If the archives log files would be between 98 and 100 MB person would notice.
The main concern that one must have for newspapers of archives files is a possible corruption. This can be easily verified by attempting a resumption of testing. When it's ok, the size of the log archive uneven should be of no interest, as is expected.
