Redolog files to physical standby standby in 11g

Hi all

Configure a physical in 11 g standby database on Linux.

My first question is, Create SRL (Standby Redo Logs)-

Is - mandatory to set up physical standby?

If I create SRL , what would be the advantage for the installation of DR?

If I ignore it, what would be the downside for the installation of DR?

Hello;

Laughing out loud

But it is a good idea.

If your database pending is in maximum protection or maximum availability mode you need.

If you use Real Time apply on Standby Database you need.

If you use cascading Destinations you need.

If you create both primary and Standby you pass quickly without additional measures or issue.

Redo Eve can also buffer it again entering.

Best regards

Waiting for redo log file missing when restore main database using RMAN backup that was taken on the database physical standby

Here's my question after tons of research and test without have the right solutions.
Target:
(1) I have a 12.1.0.2 database unique main enterprise 'testdb' as database instance running on the server "node1".
(2) I created physical standby database "stbydb" on the server "node2".
(3) DataGuard running on the mode of MaxAvailability (SYNC) with roll forward in real time 12 default c apply.
(4) primary database has 3 groups of one-man redo. (/oraredo/testdb/redo01.log redo02.log redo03.log)
(5) I've created 4 standby redo logfiles (/oraredo/testdb/stby01.log stby02.log stby03.log stby04.log)
(6) I do RMAN backup (database and archivelog) on the site of relief only.
(7) I want to use this backup for full restore of the database on the primary database.
He is a DR test to simulate the scenario that has lost every primary & Eve total servers.
Here is how to save, on the database pending:
(1) performance 'alter database recover managed standby database Cancel' to ensure that compatible data files
(2) RMAN > backup database;
(3) RMAN > backup archivelog all;
I got elements of backup and copied to primary db Server something like:
/Home/Oracle/backupset/o1_mf_nnndf_TAG20151002T133329_c0xq099p_.BKP (data files)
/Home/Oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.BKP (spfile & controlfile)
/Home/Oracle/backupset/o1_mf_annnn_TAG20151002T133357_c0xq15xf_.BKP (archivelogs)
So here's how to restore, on the main site:
I clean all the files (data files, controlfiles oder all gone).
(1) restore spfile from pfile
RMAN > startup nomount
RMAN > restore spfile from pfile ' / home/oracle/pfile.txt' to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
(2) modify pfile to convert to db primary content. pFile shows below
*.audit_file_dest='/opt/Oracle/DB/admin/testdb/adump '
* .audit_trail = "db".
* full = '12.1.0.2.0'
*.control_files='/oradata/testdb/control01.ctl','/orafra/testdb/control02.ctl'

* .db_unique_name = "testdb".
*.diagnostic_dest='/opt/Oracle/DB '
* .fal_server = "stbydb".
* .log_archive_config = 'dg_config = (testdb, stbydb)'
* .log_archive_dest_2 = "service = stbydb SYNC valid_for = (ONLINE_LOGFILE, PRIMARY_ROLE) db_unique_name = stbydb'"
* .log_archive_dest_state_2 = 'ENABLE '.
*.log_file_name_convert='/testdb/','/testdb /'
* .memory_target = 1800 m
* .open_cursors = 300
* runoff = 300
* .remote_login_passwordfile = "EXCLUSIVE."
* .standby_file_management = "AUTO".
* .undo_tablespace = "UNDOTBS1.
(3) restart db with updated file pfile
SQLPLUS > create spfile from pfile='/home/oracle/pfile.txt'
SQLPLUS > the judgment
SQLPLUS > startup nomount
(4) restore controlfile
RMAN > restore primary controlfile to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
RMAN > change the editing of the database
(5) all elements of backup catalog
RMAN > catalog starts by ' / home/oracle/backupset / '.
(6) restore and recover the database
RMAN > restore database;
RMAN > recover database until the SNA XXXXXX; (this YVERT is the maximum in archivelog backups that extends beyond the scn of the backup of the data file)
(7) open resetlogs
RMAN > alter database open resetlogs;
Everything seems perfect, except one of the file log roll forward pending is not generated
SQL > select * from v$ standby_log;
ERROR:
ORA-00308: cannot open archived log ' / oraredo/testdb/stby01.log'
ORA-27037: unable to get file status
Linux-x86_64 error: 2: no such file or directory
Additional information: 3
no selected line
I intended to use the same backup to restore primary basic & helps record traffic and the downtime between them in the world of real output.
So I have exactly the same steps (except STANDBY restore CONTROLFILE and not recover after database restore) to restore the database pending.
And I got the same missing log file.
The problem is:
(1) complete alert.log filled with this error, not the concern here
(2) now repeat it in real time apply won't work since the Party shall LGWR shows always "WAITING_FOR_LOG."
(3) I can't delete and re-create this log file
Then I tried several and found:
The missing standby logfile was still 'ACTIVE' at present RMAN backup was made.
For example, on db standby, under Group #4 (stby01.log) would be lost after the restoration.
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 19 ACTIVE 133632
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
So until I take the backup, I tried on the primary database:
SQL > alter system set log_archive_dest_state_2 = delay;
This was the Group of standby_log side Eve #4 was released:
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 0 0 UNASSIGNED
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
Then, the backup has been restored correctly without missing standby logfile.
However, to change this primary database means break DataGuard protection when you perform the backup. It's not accept on the production environment.
Finally, my real questions come:
(1) what I do may not do on parameter change?
(2) I know I can re-create the control file to redo before delete and then recreate after. Is there any simple/fast to avoid the standby logfile lost or recreate the lost one?
I understand that there are a number of ways to circumvent this. Something to keep a copy of the log file waiting restoration progress and copy up one missing, etc, etc...
And yes I always have done no real-time applies "to the aid of archived logfile" but is also not accept mode of protection of production.
I just want proof that the design (which is displayed in a few oracle doc Doc ID 602299.1 is one of those) that backs up data backup works effectively and can be used to restore the two site. And it may be without spending more time to resume backups or put the load on the primary database to create the database before.
Your idea is very much appreciated.
Thank you!

Hello

1--> when I take via RMAN backup, RMAN does not redo log (ORL or SRL) file, so we cannot expect ORLs or SRL would be restored.

2nd--> when we opened the ORL database should be deleted and created

3rd--> Expecting, SRL should not be an issue.we should be able to do away with the fall.

If you do, you can recreate the controlfile without waiting for redo log entry...

If you still think it's something is not acceptable, you must have SR with support to analyze why he does not abandon SRL when controlfile_type is "underway".

Rename a data file in a physical standby

Hi all
I have the following problem.
Oracle Enterprise Linux 64-bit 11.2.0.2.0
Primary and standby are configured with standby_file_management = MANUAL
I added a tablespace with a primary data file a few days ago.
Today, I realized sleep did not change due to the following error:

ORA-01111: name for the data file 13 is unknown - rename it to the correct file
ORA-01110: data file 13: ' / oracle1/11.2.0.2/dbs/UNNAMED00013'
ORA-01157: cannot identify/lock data file 13 - see DBWR trace file

ORA-01110: data file 13: ' / oracle1/11.2.0.2/dbs/UNNAMED00013'
According to the MOS it says I should rename database in standby mode, but it does not allow me to do so, it is said that dB must be open; but I can't open it because it is a standby DB.
Even if I want to open read-only, it says:
SQL > ALTER DATABASE OPEN read-ONLY.
ALTER DATABASE OPEN READ ONLY
*
ERROR on line 1:
ORA-10458: standby database requires recovery
ORA-01157: cannot identify/lock data file 13 - see DBWR trace file

/Oracle1/11.2.0.2/DBS/UNNAMED00013 data file does not exist
How can I solve it?
Thank you very much.

Like to, its due to the following bug.

Bug 5889025 : FINISHING SWITCH GENERATES INCORRECT STANDBY REDO LOG.

This bug refers to version 9i and standby redo logs/realtime concept is not available.

OP using the 11g version... Although if you see in the State of the article, the State is "92 - closed, not a Bug", according to me this is the default behavior and is not bug.

Move the data files on the standby server without moving primary Oracle 11 g r2

Hi all

Oracle 11g 2 with EBS 11.5.0.2 version.

The size of one of the mounting points on the standby is full and I'm going through one of the data files to another mount point without making any changes to the primary level.

I tried Google and came across this link:

http://oraclesea.blogspot.in/2011/12/move-datafiles-on-standby-server.html

But it did not work... I had to start the database with the spfile to work.

The steps mentioned in the blog:

Include below parameter in standby parameter file
DB_FILE_NAME_CONVERT = '/primary_location/xyz.dbf','/standby_location/xyz.dbf'
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE cancel;
shut immediate
startup nomount pfile=initSCSL.ora
alter database mount standby database ;
alter system set standby_file_management='MANUAL' SCOPE=MEMORY ; 
! cp /primary_location/xyz.dbf'  /standby_location/xyz.dbf
alter database rename file  '/primary_location/xyz.dbf' to '/standby_location/xyz.dbf';
alter system set standby_file_management='AUTO' SCOPE=MEMORY ; 
alter database recover managed standby database parallel 4 disconnect from session;

Can you please help me with the right steps...

Concerning
KK

1. you must close the database pending.
2 copy the file that you want to move to the different mount point using the OS commands.
3. Mount the standby database.
4 rename the data through database level. Make sure that the standby_file_management is set to MANUAL
5. start the MRP on the standby database.

Physical standby Archive newspapers vs

Hi all
11 GR 2
Rhel6.5
I'm confused how archivelogs be appied physical standby.
CASES1:
Assuming I backup my primary Db with RMAN full backup now.,
then question crosscheck backup and delete obsolete. It will remove all archivelogs not yet taken to the waiting?
CASE2:
Right now my database pending is on a mode "real apply", so updates to the primary level is done directly on the eve as well, even if the archive logs have not yet carried.
Assuming that I will delete archive records at the primary level, such that it cannot carry, will be the sleep EEG 'gaps' in its Archives logs status?
Your comments are appreciated hightly.
Thank you very much

Test of physical Standby DB 11 g

Hi all
My company is considering a DR test in a few months, and since I never did this until I was wondering what would be the best way to go on the DB pending tests. This is a database of 11G (11.2.0.3). I read the following articles:
http://gavinsoorma.com/2009/09/11g-snapshot-standby-for-real-time-testing/
http://www.Pythian.com/blog/testing-a-physical-standby-database-in-Oracle-10G/
http://www.Oracle.com/technetwork/articles/SQL/11g-DataGuard-083323.html
From what I can tell the snapshot method is the easiest. My main question is when the primary method still must send the archive logs to the waiting or can I defer only to archive log shipping? How we test normally the site of DR is completely disconnect the network connections and put everything in place for the primary will not be able to speak to the waiting and vice versa. Or is the best method to follow the other article that speaks using the flashback database?
Thanks in advance for your help.

From what I can tell the snapshot method is the easiest. My main question is when the primary method still must send the archive logs to the waiting or can I defer only to archive log shipping?

Are you in 11g, yes instant is a nice feature to test your intelligence. If you enable the destination, there is no problem. Meanwhile if too many records are generated and then it takes a long time to get a site to DR.

How we test normally the site of DR is completely disconnect the network connections and put everything in place for the primary will not be able to speak to the waiting and vice versa

You can also completely disconnect the primary DR and tests after the conversion of the physics on the eve of the snapshot if it is your condition to do so.

Or is the best method to follow the other article that speaks using the flashback database?

In traditional flashback, you will need to take care just like the creation of restore point with guarantee, mode standby manually and run again then flashback to the restore point. Snapshot is really simple and easy to use. If am in your position of course I use the standby database snapshot.

Problem creating physical standby with RMAN

Hi guru
Perhaps this impact that all face you when creating physical standby DB. I'm trying to create a physical standby database Using RMAN double order a server
(pri machine) machine on standby.
Here are the steps I followed to create the above:
Step 1:-activate forced logging
SQL > ALTER DATABASE FORCE LOGGING;
Step 2:-set up a standby Redo Log
SQL > ALTER DATABASE ADD STANDBY LOGFILE GROUP 10
2 > ('/ oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500 M;
Step 3:-set the parameters of primary database initialization
SQL > create pfile='?/dbs/pfileorcl.ora' of spfile;
Edit the pfile to add the sleep settings, shown here:
db_unique_name = "orcl".
LOG_ARCHIVE_CONFIG = 'DG_CONFIG = (ORCL, orcldr)'
LOG_ARCHIVE_DEST_2 = "SERVICE = orcldr LGWR ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = orcldr'"
* .fal_server = orcldr
* .fal_client = orcl
* .standby_file_management = auto
Step 4:-activate archiving
SQL > SHUTDOWN IMMEDIATE;
SQL > STARTUP MOUNT;
SQL > ALTER DATABASE ARCHIVELOG;
SQL > ALTER DATABASE OPEN;
Step 5:-tnsnames for eve of the configuration database
This should be done on the primary database to edit tnsnames.ora or using the command NetCA and create by the name orcldr
orcldr =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = Eve-svr)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcldr)
)
)
Step 6:-backup of database and copy it to standby mode
This backup script must be run on primary and copied to sleep on the same mount point, run these scripts with RMAN, all files in /rman_backup need to be copied in /rman_backup on the standby server.
$rman target.
RMAN > run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
backup of database format ' / rman_backup/%U';
ARCHIVELOG backup all the format ' / rman_backup %U ';
backup current controlfile to Eve format ' / rman_backup/%U';
}
Step 7:-availability of measures database
Installation of Oracle software
This should be the same version and patch group with exactly same ORACLE_HOME mount point.
Commissioning of the listener
Create and start a listener on the database of sleep by using NetCA, or create listener.ora in $ORACLE_HOME/network/admin
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = Eve-svr)(PORT = 1521))
)
Step 8:-set of backup database initialization parameters
Copy the pfile file created in the database primary it renames in initorcldr.ora and change these settings:
db_unique_name = "orcldr".
LOG_ARCHIVE_CONFIG = 'DG_CONFIG = (orcldr, ORCL)'
LOG_ARCHIVE_DEST_2 = "SERVICE = orcl LGWR ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = orcl'"
* .fal_server = orcl
* .fal_client = orcldr
*. LOG_ARCHIVE_DEST_STATE_2 = 'ENABLE '.
Step 9:-installation tnsnames for the primary database
This should be done on the pending change tnsnames.ora or using the command NetCA database and create it in the name orcl
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = primary-svr)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
Step 10:-copy a password file
A password file must be created on the primary and copied to the standby site. The sys password must be the same on both sites. Copy orapworcl in $ORACLE_HOME/dbs and rename the file in orapworcldr
Step 11:-create for Oracle mount points
Mount point must be created on the standby server with the same convention used in primary education, which includes the location for controlfiles, redo logs, data files, destination of the newspaper Archives and alert logs.
$ mkdir Pei/u01/app/oracle/oradata/orcl /.
$ mkdir Pei/u01/app/oracle/flash_recovery_area /.
$ mkdir Pei/u01/app/oracle/admin/orcl/adump
$ mkdir Pei/u01/app/oracle/admin/orcl/bdump
$ mkdir Pei/u01/app/oracle/admin/orcl/cdump
$ mkdir Pei/u01/app/oracle/admin/orcl/udump
Step 12:-use RMAN to restore the backup and standby configuration
Connecting to RMAN and run the following command to create the database pending, this must be performed on the standby server after the backup copy and the tnsnames parameter.
$ export ORACLE_SID = orcldr
$ rman target sys/tiger@orcl auxiliary sys/tiger@orcldr
RMAN > target double standby database dorecover;
Here, I'm getting problem such as:
While he was trying to connect to databases traget and auxiliary, I noticed that when RMAN is connected across the two databases it shows
ORCL (DBID xyz)
ORCL (unmounted)
Here, in my opinion the second database must be the name of the standby database or auxiiary db name is Eve db which is orcldr in my case
After this issue, I am faced with the second issues such as:
in command
target double standby database dorecover;
After you change the command to
RMAN > duplicate target database "sleep."
RMAN-05520 database name mismatch
Can u please let me know where I can be wrong

Finally I have the problem after all this googling and thinking the same thing.

Thanks to you all

RAC ASM database and system files in the standby mode
I have a database of ASM the knot two of the CARS and want to create a physical file system standby active database. This is supported by oracle? and you can share tips? Thank you

How to check if physical Standby is in phase with the primary

Hi all

I'm new in Data Guard. In our current production, my boss asked me to write a shell scripts for monitoring physical standby and archive primary's sync (gap of archive)

I refer metalink [861595.1 ID], but when I ran the first query to the primary node, the screen lock.

On primary
========

SQL > SELECT THREAD # "Thread", SEQUENCE # 'last generated sequence.
V $ ARCHIVED_LOG
WHERE (THREAD #, FIRST_TIME) IN (SELECT THREAD #, MAX (FIRST_TIME) FROM V$ ARCHIVED_LOG GROUP BY THREAD #)
ORDER BY 1;

I tried to turn on 10046 trace SQL, SQL consume a lot of CPU and it full table scan in X table KCCAL $.

Eye of TKPROF result as below:

Because of this is the production environment, so I had put an end to the session, anyone can teach me or share with me the physical monitor in standby mode scripts is sync with primary or not? Or you encounter the above problem when you run the SQL code?

My version of db is Oracle 11.2.0.1.0

Thanks in advance.

Kind regards

Just be aware that these queries are queries controlfile and if they run too long can get in the road of the database as they hold controlfile locks. You'd better watch the view v$ dataguard_stats the day before and look at the GAL apply and transport.

We are also a few scripts in our book - http://www.amazon.com/Oracle-Guard-Handbook-Osborne-ORACLE/dp/0071621113

How to change the character of database defined on the physical standby database?
Hello

We hear a database to WE8ISO8859P1 character and migrated the character set using csscan/csalter scripts to WE8MSWIN1252. This database has a configuration also physical standby database, and after the migration, the database physical standby shows always defined as WE8ISO8859P1 character. How can I change the characters on the physics of the day before? I asked a Service request with Oracle, and they said that you re-create the database pending is the only way to support the development of the tank set to the standby database. Is this true?

Thank you
Anthony
You have received good advice from the Support of Oracle, so I recommend doing a complete refresh of Eve, but if you want to play with fire...

On the elementary level, you can: -.

target connection.
RUN {}
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT ' / home/oracle/rman_%d_%T_%s_%p';
BACKUP CURRENT CONTROLFILE TO SLEEP;
}

or

ALTER DATABASE CREATE STANDBY CONTROLFILE AS ' / home/oracle/standby.ctl';

Then you stop the watch, replace the with the new primary backup controlfile and make sure that file names are correct (select name from v$ datafile). If the file names are correct, start the recovery. Otherwise, rename files, or difficulty with the rman command 'catalogue start with '.

Problem with data hold creating a Physical Standby Database turorial
There is a tutorial for creating a Data Guard Physical Standby Database:
http://www.Oracle.com/technology/OBE/11gr1_db/HA/DataGuard/physstby/physstdby.htm

I tried to install it on two servers. One for a primary database (deuxieme for the physical standby.
I have the error on creating C. the database of watch on the #6 action network:

«On the rescue system, set the ORACLE_SID to your < SID physical standby > environment variable (i.e. orclsby1) and start the instance in NOMOUNT mode with the text initialization parameter file.»

When I try to connect to the instance that is idle, there is an error pops up:

C:\ > sqlplus / as sysdba

SQL * more: version 11.1.0.7.0 - Production Thursday, May 21, 16:28:10 2009

Copyright (c) 1982, 2008, Oracle. All rights reserved.

ERROR:
ORA-12560: TNS:protocol adapter error

I ' v checked listener, and it is managed. There is no database service because there is still no database.

The question is did some data installed a guard configuration using this tutorial? Are there errors in there? What should I do to complete the installation?
On Windhose for any service must have been created using the oradim command.
Oracle tutorials are usually centered on Unix, because Windhose is an odd man out, so they do not discuss.
"Please do the needful" and create the service before the beginning of the instance in nomount mode

Tip: oradim is documented and has a help = clause of y.

IIRC there is an option in control database (in the part of the interview) that automates everything.

DataGuard (activate a physical standby as a stand-alone database database)?

Hi all
Can I please ask advice on how it would activate a physical database ensures for 11.2.0.4?
Note - I do not want to return the "standby" to watch again...
Note 1 – I don't have (and don't use flashback technology to do this) - so I can't use a watch "snapshot"...
Note 2 - the 'primary' current cannot be touched.
Something like below?
Repeat stop applies to pending
SQL > alter database recover managed standby database cancel;
Stop redo pending transaction logs.
PRIMARY
SQL > ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2 = DELAY;
Activate and open the database physical sleep.
Physical STANDBY
SQL > ALTER DATABASE ENABLE PENDING DATA base;
SQL > STARTUP MOUNT FORCE;
SQL > alter database base_de_donnees ensures together to improve performance;
SQL > ALTER DATABASE OPEN;
Concerning

It wouldn't affect Production (primary). It's just the steps of failover.

The same applies to the role transition, but in a role transition, you must first pass at the primary level of Eve and the day before, you must run the digital switchover to make primary.

You could refer to this https://docs.oracle.com/cd/E11882_01/server.112/e41134/role_management.htm#SBYDB4769 you would get to the difference of the steps for the passage and failover.
