Data guard difference in primary and standby OS.
Dear All,
We are planning to setup a data guard in our landscape. But my question what are the prerequisites should be consider before getting in to that.
Like my environment -
1. The primary database is running with Red hat Linux 5 - IBM 64 bit and the standby database is Redhat Linux 2.1 IBM 32 bit system.
2. The primary database is running with Red hat Linux 5 - IBM 64 bit with oracle 8.1.7.4 and the standby database is
Linux 2.1 IBM 32 bit system with oracle 10g.
Is the above thing is possible? or we should maintain the same OS / DB combination in the data guard setup.
I am following the below link.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm#i72053
If anyone have thoughts on this please do advice me.
Regards
Vijay
Please explain to us what exactly you want to do with the standby database?
According to note 105047 - Support for Oracle functions in the SAP environment
12. Data Guard
You can use "Physical Standby", but Oracle provides support (not SAP).
You cannot use "Logical Standby"
So in short, no a data guard configuration with Red hat Linux 5 - IBM 64 bit with oracle 8.1.7.4 to Linux 2.1 IBM 32 bit system with oracle 10g is NOT possible.

Oracle data guard configuration for primary and standby db_name
I am working on configuring an active data guard for one primary DB and one standby DB. I have a few questions:
1. Can I use different db_name, db_unique_name and instance_name for primary and standby. For example: primary(db_name, db_unique_name and instance_name)=chicago. When I create standby DB with Rman backup and copy of pfile and control file from primary DB or use Grid control to create standby database. Oracle document or Grid control all keep standby db_name=chicago. Only make standby db_unique_name and instance_name=boston. Due to my application system condition, I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?
2. In primary datafiles, application system generate datafile name like this: hr_chicago_01.dbf, fn_chicago_01.dbf. When I move datafiles to standby server, if I plan to use db_name=boston for standby DB, can I rename datafiles as
hr_boston_01.dbf, fn_boston_01.dbf? In this way, datafile name match up with db_name. but I will create standby log group and members on primary and standby identically. If in future switching over, DB will not have problems.
3. If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standby. Then "alter database backup controlfile to trace" from promary and also " create pfile='/xxx/initSTANDBY.ora' from primary. Then modify init.ora and controlfile. Then run control.sql to bring standby DB up. After that, configure redo log shipping and apply with data guard or SQL. Is this a acceptable way to create physical standby DB?
Please advise your comments. Thanks in advance.I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?NO. DB_NAME must be the same ("chicago") at both sites. The Standby will be using a different DB_UNIQUE_NAME (e.g. "boston") and can be using a different Instance name / SID (e.g. "boston").
can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''

Steps for Data Guard with one primary and 2 standby
Hi,
Database :10.2.0.4, 11.2.0.1
Os: Windows , Unix
A ----------------> Primary database
B ----------------> Standby Database 1
C ----------------> Standby Database 2
I want to configure *2 standby* databases for single primary database.
Lets take, A ,B and C are my machines.My data guard configuration will be like,*archive logs will be moving* from A to B and A to C.
If i do any switchover in between A and B , now B is primary and remaining A and C are standby databases.At this stage also , archive logs should move from B to A and B to C. Also, same should happen from C to A and C to B,If i do switchover in between B and C.If everything is fine , then i will do switchback to main Primary database(A).
How do i have to mention PFILE in all machines ,the parameters like
LOG_ARCHIVE_DEST_1=LOCATION=<PATH> -- LOCAL ARCHIVE PATH
LOG_ARCHIVE_DEST_2=SERVICE=
LOG_ARCHIVE_DEST_3=SERVICE=
FAL_SERVER=
FAL_CLIENT=
STANDBY_FILE_MANAGEMENT=
In my tnsnames.ora , primary,standby1 and standby2 are my service entries and these are same in all of my machines.
Please suggest me , how do i can configure my pfiles in all machines ?.
Thanks,
SunandNot yet, but now you have me interested.
Please consider Flashback.

SCN number difference in primary and standby databases
Hi All,
Is it possible that primary database SCN is 20 and standby database SCN is 22 ? If yes , how it works ?
Thankyou !I agree that it is possible depending on your setup. However, I read your posting and BLOG entry but it does not address out the Standby database has a GREATER SCN than the Primary.
The answer will depend on the type of standby database you have configured (LOGICAL vs PHYSICIAL) and perhaps if it is a SNAPSHOT Standby that has been used and not rolledback.
In what I would consider "Normal" situations the SCN of the standby database would always either be at the same SCN or be lagging.
I have not tested it but I could see where if you had a standby database that you converted to a SNAPSHOT Standby (11g ability), made changes to the standby and had not converted it back to a normal Standby then your SCN can be ahead in the standby because the changes had not been discarded yet.
Regards.

Time zone difference between primary and physical standby
Dear Team,
We have Primary database server (with EST Time zone) and physical standby (with PST time zone), in case of switch over/fail over to physical standby
what are the major impacts.
Is it mandatory to be in time sync?
Thanks in advance
AjCURRENT_TIMESTAMP
04-FEB-10 10.22.20.444692 AM +05:30
( above is same on primary and standby)
SQL> select systimestamp from dual;
SYSTIMESTAMP
03-FEB-10 08.52.46.934125 PM -08:00
(above is 3hr diff from primary and standby)It is 13hrs difference
One is around Indian subcontinent and other should be in US western region ?
Systimestamp is the timestamp of the OS of the server and hence the difference and the sysdate value will be from systimestamp and if the applications uses SYSDATE then there can be an issue... -
Data Guard Failover after primary site network failure or disconnect.
Hello Experts:
I'll try to be clear and specific with my issue:
Environment:
Two nodes with NO shared storage (I don't have an Observer running).
Veritas Cluser Server (VCS) with Data Guar Agent. (I don't use the Broker. Data Guard agent "takes care" of the switchover and failover).
Two single instance databases, one per node. NO RAC.
What I'm being able to perform with no issues:
Manual switch(over) of the primary database by running VCS command "hagrp -switch oraDG_group -to standby_node"
Automatic fail(over) when primary node is rebooted with "reboot" or "init"
Automatic fail(over) when primary node is shut down with "shutdown".
What I'm NOT being able to perform:
If I manually unplug the network cables from the primary site (all the network, not only the link between primary and standby node so, it's like a server unplug from the energy source).
Same situation happens if I manually disconnect the server from the power.
This is the alert logs I have:
This is the portion of the alert log at Standby site when Real Time Replication is working fine:

Do you have any advice?

Alex.Hello;
What's not clear to me in your question at this point:
What I'm NOT being able to perform:
If I manually unplug the network cables from the primary site (all the network, not only the link between primary and standby node so, it's like a server unplug from the energy source).
Same situation happens if I manually disconnect the server from the power.
This is the alert logs I have:"
Are you trying a failover to the Standby?
Please advise.
Is it possible your "valid_for clause" is set incorrectly?
Would also review this:
ORA-16014 and ORA-00312 Messages in Alert.log of Physical Standby

Require 9i Primary and Standby redo logs files same size?
Hi,
We have 9.2.0.6 Oracle RAC (2 node) and configured data guard (physical standby).
I want to increase redo log files size, but i can't this do same time primary and standby side.
Is there a rule, primary and standby database instances have same size redo log files?
If I increase only primary redo log files, is there any side effect? However I try this issue on test system. I increased all primary redo log files(if status='INACTIVE' drop redo log group and add redo log group, switch logfile,...)
, but i couldn't changed standby side. So the system is work well. Is this correct solution or not? How can i increase both sides redo log files?
Thank you for helps..Thank you for your helps.. I found this issue answer:
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/manage_ps.htm#i1010448
Consequently, when you add or drop an online redo log file at the primary site, it is important that you synchronize the changes in the standby database by following these steps:
If Redo Apply is running, you must cancel Redo Apply before you can change the log files.
If the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO, change the value to MANUAL.
Add or drop an online redo log file:
To add an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE ADD LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log' SIZE 100M;
To drop an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE DROP LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log';
Repeat the statement you used in Step 3 on each standby database.
Restore the STANDBY_FILE_MANAGEMENT initialization parameter and the Redo Apply options to their original states.

Data Guard with Oracle 9i and 10g -- have you done it?
We have an ERP system (JDEdwards, db size approx 600 GB) and we'd like to copy the data in this system to a database on another computer. We'd use the remote database for reporting, so we need it to be available. We are looking at using Data Guard running in Logical Standby mode.
The ERP database is Oracle 9i, and we are considering having the Logical Standby database be 10g. Have you done this and if so, what was your experience?
Here's why we want to do this. There are many tables in the ERP database that contain descending indexes. We can't change this, and it is not supported with Data Guard under Oracle 9.2. Tables with descending indexes do not copy to the logical standby database.
We were told that this is corrected in a newer release of Oracle, and we were wondering if a 10g database would properly copy tables with descending indexes.
Thanks in advance for any experiences you can share.
Best Regards,
MikeWhat you are trying to do might not be possible. Because when you create logical standby you have to create a physical standby first and convert it. Primary and standby have to be same version.
In furture it might be possible because 10G will support rolling upgrade of logical standby.
However even it's possible you have to go through a lot of pain to setup and maintain it because Oracle don't support the setup.
What you could try are Stream and Replication, I will say Stream is very interesting one. Because Oracle say : "Oracle Streams and Oracle Data Guard (including Data Guard SQL Apply) are independent features based on some common underlying infrastructure and technology. "

Hello everybody i use Oracle Database EE 11.2.0.4 with DG.
In those cases i need to get Enterprise Manager Database Control running against DB with no RAC and no DG i perform the following steps:
I Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects:
DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
END IF;
END LOOP;
END;
DROP USER mgmt_view CASCADE;
DROP ROLE mgmt_user;
DROP USER sysman CASCADE;
After that i run
emca -config dbcontrol db -repos recreate
But what should i do in cases i have 2 servers working (primary and standby) under DG rules?Hi ,
It is not possible to monitor/administer a Logical or Physical Standby database, i.e Data Guard, using Enterprise Manager Database Control. This is primarily due to the fact that Database Control is designed to monitor 1 database and a Data Guard environment, by definition, includes more than 1 database.
If you attempt to run emca against a standby Database, you will get an error like (i.e. ORA-01219: database not open).
Database Control, can, of course, be used to monitor the current Primary database (with no ability to administer or monitor Data Guard related functionality). In such a case, when failover occurs Database Control must be reconfigured to run on the new Primary database using the commands detailed in Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database, section C. Recreate/ReConfig DB Control, Option 2. Recreate the DB Control Configuration Files and Repository.
Enterprise Manager Grid Control or Cloud Control provides the functionality for viewing, monitoring, and administering primary and standby databases in a Data Guard configuration.
Reference: Is it Possible to Configure Database Control for a Logical or Physical Standby Database? (Doc ID 315116.1)
You can use EM 12c cloud control to monitor and manager Standby DB effectively

Can I have primary and standby in same OS but different releases.
All,
Can I have primary and standby DBs in same OS but in different releases?
i.e. primary is in RHEL 5 and standby is in RHEL 4, is it ok to setup or do we see any issues?
Thanks,
MahiIn 10g, dataguard started to support different binaries on primary and standby database servers with the same OS family. For example Microsoft Windows 64-bit on primary and Microsoft Windows 32-bit or Microsoft Windows 64-bit for AMD on standby database server. However with 11g, dataguard also supports different OS on primary and standby servers

DNS / BIND - Can I configure primary and standby forwarders?
Hi all,
I have on Solaris 10 (x86) a DNS server (BIND 9.3.6-P1) that relies exclusively on two “forwarders”: 155.28.144.13and 154.23.134.32.
The configuration is as follow:
# cat /etc/named.conf
acl "CSClan" { 192.168.4.0/24; 192.168.7.0/24; }; //CSC internal LAN ip address range
options {
directory "/var/named";
forward only;
forwarders {
155.28.144.13;
154.23.134.32;
allow-query { "localnets"; };
# cat /etc/resolv.conf
nameserver 127.0.0.1
When I check with snoop, I can see requests sometimes to one forwarder, sometimes to the other.
Is it possible to configure DNS to use primarily one forwarder?
Thanks in advance for your support.

Purging archivelogs on Primary and Standby
Hi all,
11.2.0.1
Aix 6.1
I am monitoring space usage in our FRA for both DG primary and standby. I want to purge all archivelogs once they have been applied to standby. What is the use of it anyway?
I checked google and I found this procedure, kindly correct if this is wrong?
At Primary:
=========
RMAN
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
At Standby:
========
RMAN
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
Where do I issue the command DELETE NOPROMPT OBSOLETE ARCHIVELOGS?
Thanks a lot,
zxyWhich tool in oracle dear maintains the FRA/achivelogs? is it RMAN or Dataguard. If it maintains
them auto, why is that I still have lots of archivelog at PRIMARY and STANDBY?

Taking RMAN backup of primary and standby databases.
Hi,
I am going to setup a Standby for Primary two node RAC to single node standby.
My doubt is, in standby both primary and standby will have the same db_name. So how can i take the RMAN backup of both primary and standby by using a single catalog.
That is, we can register the primary DB with catalog using it's db_name. But how can we register the standby with catalog using same db_name as it is already registered.
Thanks,
MahiAre you using a physical or logical standby?
If its a physical standby why do you need to back up both databases? backup the standby and you are done, the backup from the standby can be recovered to either the live serever or the standby if needed, andt hen the archivelogs used to bring it up to date.
If its a logical standby then change the database name for the standby and you can back both up to the same catalog, or alternativly cretae a new catalog for the standby, either as a new database or a new schema in your existing catalog.
Maybe you are looking for
