Physical Standby DB and Oracle Encryption Wallet

I remember reading somewhere that it is recommended to have your encryption wallet set to auto open on your standby database but I am not sure of the reason for this. Can anybody tell me? We are not planning to have an auto open wallet on our primary to help with the separation of duties.
Oracle version 11.2.0.1 Enterprise
OS = Windows Server 2003 R2

Hi, i found that recommendation here : http://books.google.com.tr/books?id=tdRes4IdLiIC&lpg=PA241&ots=7Rt_1eergo&dq=manual%20%22auto%20open%20wallet%22&pg=PA609#v=onepage&q&f=false
It says unless dialing with dataguard setup, Oracle recommends an encryption wallet (manual open wallet)
I think it's recommended because it's automatically opened in database restart. In a dataguard configuration it may be risky to manage primary & standby wallets manually.

Difference between physical standby database and Data Guard

Hi guys,
Today I attended one interview. They asked me a difference between the Oracle Physical Standby database and Oracle Dataguard?
Upto my knowledge Oracle Physical Standby Database is one type of Standby Database can be configured using Oracle Databaguard Feature.
Can you people calrify me on this.
Regards,
Vijayaraghavan K

hello,
yes you are right upto some extent...here is para form oracle doc
Oracle Data Guard is the most effective and comprehensive
data availability, data protection, and disaster recovery solution
for enterprise databases. It provides the management, monitoring,
and automation software infrastructure to create and maintain one
or more synchronized standby databases to protect data from failures,
disasters, errors, and corruptions.
Data Guard standby databases can be located at remote disaster
recovery sites thousands of miles away from the production data center,
or they may be located in the same city, same campus,
or even in the same building. If the production database
becomes unavailable because of a planned or an unplanned outage,
Data Guard can switch any standby database to the production role,
thus minimizing downtime and preventing any data loss.oracle data guard is maximum availiblity solution which maintain physical standby databases and in case of failure of production can switch production role to and standby database.

Question-Recovering tablespace in physical Standby...Oracle 10g?

Hello:
I have an interesting issue. I thought I will ask the group.
I have a physical standby database in 10g. Once of the datafile is in inconsistent state due to a crashed DB during recovery from the last time around.
I do not have any archivelogs, either on standby or primary .. Unfortunately.
However, the primary database is alive and well.
How do I recover my datafile selectively? Is a complete restore/recreation of the standby is the only option?
Any ideas?
Thanks in advance.

Dear user13295317,
Here is the error explanation;
Oracle Error :: TNS-12533
TNS:illegal ADDRESS parameters
Cause
An illegal set of protocol adapter parameters was specified.
In some cases, this error is returned when a connection cannot be made to the protocol transport.
Action
Verify that the destination can be reached using the specified protocol.
Check the parameters within the ADDRESS section of TNSNAMES.ORA.
Legal ADDRESS parameter formats may be found in the Oracle operating system specific documentation for your platform.
Protocols that resolve names at the transport layer (such as DECnet object names) are vulnerable to this error if not properly configured or names are misspelled.Hope That Helps.

How to stop and cancel physical standby database (ORACLE 10g)

Dear All,
I have physical standby setup and I want stopped for the time being that to use the database as an normal DB (standalone inestance).
Kindly advise and show me how do I do that.
Regards,

executing below query on primary db stops log shipping to standby.......i think this is sufficient for disabling your physical standby setup temporary
alter system set log_archive_dest_state_2=defer scope=both;
In future if you want your dataguard setup back..............you can rebuild the standby and enable the log_archive_dest_state_2 parameter.

ARCHIVELOG deletion on primary and physical standby

Hi,
We have a primary and a physical standby database running Oracle 11.1.0.7.0 software on Red Hat Enterprise Linux x-64 bit OS. I will be using backup software
to only backup the primary database and do not have the backup software for the standby server and database.
We need to backup archived redo log files from primary site and delete the ones which are more than one month old. These archived redo log files will be applied from primary to standby database as and when the log switch occurs.
Can anybody please let me know if the following steps can be used:
Details are:
primary database name - sun (machine name is node1)
standby database name - drsun (machine name is node2)

Hello;
Welcome to the forums. ( By physical Standby I assume Data Guard )
The short answer is it should work. I noticed this :
/cleanup_rman_arch_drsun.rcv
crosscheck archivelog all;
sql "alter system switch logfile";
delete noprompt expired archivelog all;
change archivelog until time 'SYSDATE-1' delete;I see no reason for the "alter system switch logfile". In fact you can do something very simple on the Standby :
$ORACLE_HOME/bin/rman target / catalog <user>/<password>@<catalog> << EOF
delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-1';
exit
EOFThis assumes you have doing a backup with RMAN on the Primary ( tested on 11.2.0.2 ) and have this set on the Primary :
CONFIGURE ARCHIVELOG DELETEION POLICY TO APPLIED ON ALL STANDBY;
If you are deleting Archive without using RMAN first then yes something like this ( But I would try to use RMAN and not delete using another method )
echo `date`
echo "Runnung RMAN archive crosscheck"
$ORACLE_HOME/bin/rman <<EOF
connect target /
crosscheck archivelog all;
delete noprompt expired archivelog all;
exit
EOF
echo `date`

Data Guard Archive Log Latency Between Primary and Physical Standby

How can I get the time it takes (latency) for the primary instance to get an archive log over to the physical standby instance and get it "archived" and "applied". I have been looking at the V$ARCHIVED_LOG view on each side but the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY" and no timestamp. I thought the DATE datatype include data and time. Any ideas on how I can get the latency info I'm looking for?
Thanks
Steve

the COLUMN "COMPLETION_TIME" always shows a date "MM/DD/YY"
and no timestamp. Did you try using TO_CHAR ? e.g.
to_char(completion_time,'dd/mm/yyyy hh24:mi:ss')

Problems while creating a physical Standby

Hi,
I am trying to setup a physical standby database with oracle 10g.
I configured a specific log archive destination:
LOG_ARCHIVE_DEST_3 = 'SERVICE=ORAMPSEC REOPEN=60 MAX_FAILURE=3 LGWR SYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=ORAMPSEC'
The service is reachable via network.
To establish the standby database I copied all datafiles from the primary database using scp. I also created a standby controlfile and a modified pfile. In addition I added a standby redo logfile which has the same size as the online redo log files on the primary database.
After starting the standby database in open read only mode I receive the following error message:
Database mounted.
ORA-16004: backup database requires recovery
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/oradata/ORAMPPRD/data/system01.dbf'
I tried to recover using "recover standby database" I receive the following message:
ORA-00279: change 884348 generated at 07/18/2006 17:08:07 needed for thread 1
ORA-00289: suggestion : /oradata/ORAMPPRD/archive/1_30_595767954.dbf
ORA-00280: change 884348 for thread 1 is in sequence #30

Although I transmitted all archived log files from the primary database the archived log file mentioned above is not available. After hitting RETURN I get this message:
ORA-00308: cannot open archived log
'/oradata/ORAMPPRD/archive/1_30_595767954.dbf'

Although there still seems to be something wrong, the archived log file transmission seems to work since there is no error reported on the log archive destination:
SQL> select status, error from v$archive_dest where dest_id = 3;
STATUS ERROR
VALID
And after I manually force a log switch I see that archived redo logs were applied on the standby database:
select sequence#, applied from v$archived_log order by sequence#;
SEQUENCE# APPLIED
27 YES
28 NO
28 YES
29 NO
29 YES
Unfortunately because of the recovering problem I cannot open the database to see if the changes were applied. So my first question is, how can I get the standby database completely recovered ??
In addition to this I was expecting that the changes to the standby database were made immediately since I choosed LGWR sync but I have to manually force the logfile switch. As I already mentioned a standby redo log file is available as well.
Thanks for your help,
Philipp.

Hi,
since it does not seem to work with just copying the datafiles I switched to RMAN. I created a full database backup from Enterprise Manager. Similiar to http://dizwell.com/main/content/view/81/122/1/1/ I tried to duplicate the database to the standby instance (running on a different server). But unfortunately I receive error messages that the files, previously created, cannot be found:

But when I crosscheck my backup inside RMAN it clearly shows the backup files:

I already checked the file permissions, everybody on the system is able to access this file.
Do you know what is going wrong here ??

Creation of logical standby in 9i from physical standby

Hi all,
I want to create logical standby from physical standby in 9i. can anyone send a doc for this

As per the Oracle documents "You create a logical standby database by first creating a physical standby database and then transitioning it to a logical standby database"
Please take a look at the below URL.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm

Clarification on creating a Physical Standby Database

I'm practicing with data guard with Oracle 10.2.0.1.0 on two Windows 2003 servers.
I'm in the process of creating a physical standby database by following the steps outlined in the guide http://www.filibeto.org/sun/lib/nonsun/oracle/10.2.0.1.0/B19306_01/server.102/b14239/create_ps.htm
I've created the primary database and did a cold backup of all the datafiles and copied them to the standby server using OS commands. I've created a pfile from the spile in primary database and changed the needed parameters for the standby database.
What I don't understand is this statement I think is creating a control file for the standby database: SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tamp/standby.ctl'
Exactly what I don't understand is what to do with this control file. I'm thinking that if I try to use it as the controlfile for the standby database, the standby database will refuse to open since the database name in the control file wont match the one the server expects.
I don't want to proceed until this becomes clear. So my question is what to do with the output of the above statement that seems to create a control file for the standby database.
Any help would be appreciated.
Dula

>
You're thinking wrong.
Please clarify the difference between db_name and
db_unique_name.
Db_unique_name needs to be identical for both primary
AND standby database.
If db_unique_name differs, you'll get errors.
Sybrand,
Perhaps, you meant DB_NAME has to be identical for both databases.
DB_NAME name has to be the same for both primary and physical standby database.
DB_UNIQUE_NAME should be unique for each database in the standby configuration.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i68626
If you configure Logical Standby Database, DB_NAME may be different.
For the original poster: Chapter 3 - Creating a Physical Standby Database of Oracle® Data Guard Concepts and Administration has all the steps you have to do in order to configure a physical standby database.

Failover To Physical Standby Database

We have 3 node RAC 11.2.0.3 Primary database data guarded to a 3 node RAC 11.2.0.3 Standby database. There is an activity scheduled to perform some of order extracts in the database which is going to result in a lot of changes. Currently the discussion is on whether what should be the quickest way to go back to a point in time before the extract process starts in case of any issues. The options that we are looking at are:
1) Create a guaranteed restore point on both the Primary and Standby and use this to flashback the database (Quick but we have had issues where in the guaranteed restore point still does not guarantee the availability of the flashback logs) - Tested
2) Use RMAN backup from a day before to restore and recover to point in time before the extract process began (Time consuming) - Tested
3) Use export backup to perform a redirected restore i.e import the data from before the extract process (Time consuming) - Tested
4) Create a guaranteed restore point on both Primary and Standby, stop the Redo Apply/Ship at the time we create the guaranteed restore point and at a point we face some issue and need to go back, simply failover to the physical standby database and then reinstate the new standby database - This has not been tested yet but seems a viable option
With regard to the point 4, note that we are not concerned about data loss as the whole point of stopping the redo apply is to prevent the standby to be caught up with Primary during the run of the extract process. The question is whether the dataguard broker will allow failover of the primary to standby, in a situation described in bullet point 4). Please advice.

Creating physical standby databases with DG Broker & OEM

Hi guys,
I manage 8i, 9i & 10g databases through OEM 10.2.0.2.
Today, I would like to create physical standby db for the most important applications. Because I'm a lazy guy, I'd like to do it the easiest way, with GUI and wizzards provided by OEM.
1. Do you know any tutorial on the Internet that would help to do it easily ? My only source up to now is the official DB broker documentation (http://download.oracle.com/docs/cd/B19306_01/server.102/b14230/toc.htm), which is 300 pages long like every Oracle doc. I'd appreciate any tutorial that could lead me straight to the essential. I've heard that is not so tricky to create a physical standby db
2. Is the procedure really different to create (and then manage) a physical standby database on Oracle 8i, 9i and 10g ? Is it possible to do it through DB Broker and OEM for every version ?
thank you for your help
Antoine

Antionio,
Oracle Documentation is the best source of configuring any Oracle component.
But, If you do not want to read the entire doc, and want to configure Dataguard Broker (without OEM), then here is the Link.

GG on Physical Standby database

Hi All,
Could anyone please let me know whether we can create extract of physical standby database Archive logs? This is oracle 9i physical standby database and I want to configure the primary extracts on standby database instead of primary production database. Also please consider that this standby database is always in recovery mode in mount stage. Is this possible?
Thanks in Advance.
Raghav

Run a test by creating an extract that creates an ASCII file. It's simple, you don't need to have a replicat or data pump. If you can read the ORLs of the standby, you'll pick up the statements from the redo apply. The problem, though, is that the physical standby is mounted, so any connections/queries requiring access to fixed tables is going to fail. Also, what DBLOGIN can be used to add trandata for a table?

Creaton of Standby database and dataguard broker

Hi Experts,
I am using Linux with Oracle version 11gR2. We have planned to create a physical standby database and also configure dataguard broker for the standby database.
Also, I've read the documents that active dataguard is a feature on 11g. Is it not possible on 10g ?
Can someone please provide me the steps to create the standby database and configure the dataguard broker.

Hello;
A simple Data Broker setup would be :
On both Primary and Standby sites, change the initialization parameter in the spfile to enable the Data guard broker.
SQL> Alter system set dg_broker_start=True scope=both;
On the PRIMARY site, open the ‘cmd’ and start Command Line Interface (CLI) of the Dataguard Broker (DGMGRL).
/home/oracle:PRIMARY >dgmgrl
DGMGRL for Linux: Version 11.2.0.1.0 - 64bit Production
DGMGRL> connect sys/password@PRIMARY
Create broker configuration.
DGMGRL> create configuration ‘broker1’ as
primary database is 'PRIMARY'
connect identifier is primary;Configuration "?broker1?" created with primary database "PRIMARY"
DGMGRL>
(‘primary’ in Connect identifier is the service name through which the broker is connected to the PRIMARY database)
Add Standby Database to the above configuration.
DGMGRL> add database 'standby' as
connect identifier is 'STANDBY'
maintained as physical;
Database "standby" added
(‘to_standby’ in Connect identifier is the service name through which the broker is connected to the STANDBY database)
Now the configuration has been set up but it is still disabled. You can view the configuration by executing:
DGMGRL> show configuration
The next step is to ENABLE the configuration ‘broker1’.
DGMGRL> enable configuration;
Enabled.
Again view the configuration.
DGMGRL> show configuration
Configuration - ?broker1?
Protection Mode: MaxPerformance
Databases:
PRIMARY - Primary database
standby - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESSIn my humble opinion its a good idea to setup Data Guard without Broker and get the "feel" of it first.
Remember, once you setup Broker, you cannot use SQL to change your Data Guard setup.

i tested with my local database ,that below:
1.backup with controlfile from standby (rman>backup current controlfile)
2.manual deleted my test db controlfile,tried to restore from backup taken from standby(rman>restore controlfile from '*****************';)
3.rman>restore database
3.but it shows error (datafile already exists) ,controlfile tried to create datafiles on standby location.
my conclusion:above my cmds used to create datafiles on standby becoz i restored with standby controlfile.
my question:what is wrong with my steps? and how to restore my (prod) controlfile from standby.and bring backup my prod db.
regards
