Standby and primary
On my Primary database
when I did archive log list, it gives me
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u04/oradata/arch/PROD/
Oldest online log sequence 29627
Next log sequence to archive 29629
Current log sequence 29629
On my standby database, when I did archive log list, it gives me
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u04/oradata/arch/STNBY/
Oldest online log sequence 29627
Next log sequence to archive 0
Current log sequence 29629
But during hotback on primary it pops up with these errors
RMAN-08137: WARNING: archive log not deleted as it is still needed
archive log filename=/u04/oradata/arch/PROD/PROD_0001_749397572_0000028449.arc thread=1 sequence=28449

RMAN-08137: WARNING: archive log not deleted as it is still needed
I am sure Standby is not in sync with primary.
Can someone explain in detail how to resolve this issue.
Any help is greatly appreciated.
Thank you

Logical standby and Primary keys
Hi All,
Why primary keys are essential for creating logical standby database? I have created a logical standby database on testing basis without having primary keys on most of the tables and it's working fine. I have not event put my main DB in force logging mode.I have not event put my main DB in force logging mode. This is because, redo log files or standby redo logfiles transforms into set of sql statements to update logical standby.
Have you done any DML operations with nologging options and do you notice any errors in the alert.log? I just curious to know.
But I wanted to know that, while system tablespace in hot backup mode,In the absence of both a primary key and a nonnull unique constraint/index, all columns of bounded size are logged as part of the UPDATE statement to identify the modified row. In other words, all columns except those with the following types are logged: LONG, LOB, LONG RAW, object type, and collections.

Is there any impact that apply Oracle CPU on standby and primary DB
We plan to apply Oracle April CPU on standby DB at this weekend. Then apply the same patch on primary DB next weekend. If I apply the patch on standby, then enable redo apply between primary and standby, is there any impact on primary DB. Theoretically, I don't think so. However, both DBs are production. I want to make sure there is no any impact by applying CPU in different time. Otherwise, I have to apply both DBs at the same time. Please advise. Thanks in advance.

I hope you read other people's post carefully. Don't pretend yourself is expert so that you can say whatever you want to say. This is the tech forum for Oracle technical people to ask question, seek help and so on. How do you know I didn't review document 278641.1 before I asked my question. Document 278641.1 only provide info on how to apply patch on primary and standby. Didn't say anything about applying the same patch on both DBs with data Guard at the different time. I just want to make sure If I apply patch on both DBs with one week difference, will this affect my primary database? Is there anything wrong here. If you paly in this forum as expert, please help people, not just look down people.
I suggest you review [url http://www.catb.org/~esr/faqs/smart-questions.html]How To Ask Questions The Smart Way.
When you ask for help, state the platform, operating system, Oracle version and patch level, no matter whether it seems important to the question or not. It most often is important. You may not know the difference between Itanium and PA-RISC, but that is important for Oracle and important for someone doing administrative work on an Oracle database to know. You should also learn to search the internet for answers to common questions. Everyone here wants to help, but few want to spoon-feed.
When you have any kind of standby, that constrains what you can do to a primary, if you want the standby to work properly. You need to understand how things get from one to the other, and how to decide when to simply rebuild the standby from scratch - and that decision is based on your configuration and requirements. You don't want to be in some undefined configuration for any period of time. -

Seeing traffic on both standby and primary servers in a serverfarm
Hi,
Is it normal to see traffic on the secondary server in a serverfarm like the below output.
If its secondary it shouldnt be recieving any traffic until the primary goes down or offline.
rserver: 192.168.10.40
192.168.10.40:8000 8 OPERATIONAL 3 118169 284
rserver: 192.168.10.41
192.168.10.41:8000 8 STANDBY 0 23798 33
Thanksyou had connections but not actually since the current counte is at 0.
Maybe the primary went down ?
Did you check the log ?
The 'show probe detail' and 'show rserver detail' ?

Version diff in standby and primary
Hi, we have production and standby setup in oracle10g. As I would like to upgrade the database from oracle10g to oracle11g. I would like to know if there is version difference in between primary (11g) and standby database (10g) will the datagaurd will sync the standby database ?
Dear Beginner,
There is nothing like version sync in Oracle Data Guard. They should be the same because at the end of the day if it is the physical standby of the production database, this means one day it could be the production database indeed. Treat the physical standby database as a prodcution database and they really should be twins on every aspects.
Regards.

Hi,
in 10g R2 , dataguard on unix HP
when connected to standby ,how can we find where is primary server ?
or :
when connected to primary ,how can we find where is standby server ?
Thank you.from the primary; look athe parameter log_archive_dest_x you'll see something like:
SQL> select name, value from v$parameter where name like '%log_ar%' ;
log_archive_dest_2
SERVICE=TEST_STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_
UNIQUE_NAME=test DELAY=120
tnsping TEST_STANDBY and here is your standby.
From the standby; query if fal_server is configured:
SQL> select name, value from v$parameter where name='fal_server';
NAME VALUE
fal_server TESTPROD
tnsping TESTPROD and here is your primary. -

Any idea what is going on..
ThanksHi, you must upraise a iTAR to Oracle Support for resolve this problem, because this behaviour is irregular and you will lost much time for analyze and resolve this problem.

Should standby and primary database use the same release version?
Then If I do upgrade, I'll have to stop the two database
and then upgrade?Hi,
Look at the requirements it is specified there. And as far as I can recollect they must match. Because standby feature differ beween the versions.
Best,

SECURITY PATCH ON STANDBY DATABASE AND PRIMARY DATABASE
I have a question on applying CPU on standby and primary database
I have a standby database on machine2 and primary on machine1
I applied a CPU patch on the Oracle Home of Standby database and
did not run the catcpu.sql as standbydatabase is in mount state.
Now i am going to apply the CPU patch on primary database.
What i need to confirm is that after i apply the patch on primary database oracle home
and run the cat cpu.sql on that do i have to do anything on the standby database
for instance rebuilding it or something or the change would be shipped to the standby
server automatically.
The purpose is to have the primary and standby database on the same patch level
in case of a failover
Please let me know asapAny one has any idea on this. Any ideas would be appreciated

Doubt regarding switchover from logical standby to primary
I am using Oracle 10g databases on Linux environment
I was trying creating a data guard configuration and once I was successfully done I created a logical standby database from the physical standby . Then I was trying to do a switchover .
By mistake I gave the prepare switchover command in the logical standby before executing it in the primary . And then when I gave it in the primary both the status turned to be "PREPARING SWITCHOVER"
In logical standby
SQL> ALTER DATABASE PREPARE TO SWITCHOVER TO PRIMARY;
Database altered.
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;
SWITCHOVER_STATUS
PREPARING SWITCHOVER
In primary
SQL> ALTER DATABASE PREPARE TO SWITCHOVER TO LOGICAL STANDBY;
Database altered.
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
PREPARING SWITCHOVERNow I am not able to commit any of them to primary or logical standby
In primary
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO LOGICAL STANDBY;
ALTER DATABASE COMMIT TO SWITCHOVER TO LOGICAL STANDBY
ERROR at line 1:
ORA-16217: prepare to switchover has not completed

In logical standby
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
ALTER DATABASE commit TO SWITCHOVER TO PRIMARY
ERROR at line 1:
ORA-16109: failed to apply log data from previous primaryLet me know what should be done now ? Is there anyway to solve this issue ?Can you try using the following first on Primary and then on Standby?

Local logical standby and remote physical standby
Dear All,
My database version is 10.2.0.1.0(production) and Operating System Linux x86-64 OS Version Red Hat Enterprise 4
Below is my configuration details:
Rprimary Database:Two Nodes RAC
StandBy Database LOCAL:Standalone database
Standby Database Remote:Two Node RAC
So,my question is, i want my local physical DR to convert into logical standby and
Remote DR will operate as physical standby as it IS.
sql>EXECUTE DBMS_LOGSTDBY.BUILD
After executing the above statement in my production primary database will there be any performance HIT.
And another important is that my above statement shouldn't affect my remote physical DR database.
Just the local DR should get converted into logical standby database
Thanks and Regards

Monoj DasIn any Data Guard environment, you can have either physical or logical or even mixed[physical + logical]
There will be no performance issue if you run the package for logical standby DBMS_LOGSTDBY.BUILD , This package provides you to manage even logical standby database. -
After switchover to standby as primary, now how to switch back
Hello DG experts:
I'm running Oracle 11.2 on Linux 5.8.
I am in the process of (trying) to mimic our existing production DG environment for testing purposes.
So far...
I've managed to set up a primary and standby database and ensured all logs apply properly.
My database name is DGTEST (on both primary and standby).
My db_unique_name is DGTEST_DG1 on primary, and DGTEST_DG2 on standby.
I performed a switchover from primary to standby, and opened the standby database as primary.
But, first thing is that when I check the switchover_status from v$database, it says: NOT ALLOWED.
Okay, so now what? Do I need to have another pfile to set specifically for when I am in primary or standby modes?
Here are relevant commands I have checked already:
on new Primary (db_unique_name = DGTEST_DG2)
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
NOT ALLOWED
SQL> select sequence#, applied from v$archived_log order by 1;
SEQUENCE# APPLIED
291 YES
292 YES
293 YES
398 YES
399 NO
400 NO
401 NO
402 NO
112 rows selected.
SQL> select destination, status, error from v$archive_dest;

on new Standby (db_unique_name = DGTEST_DG1)

SQL> select sequence#, applied from v$archived_log order by 1;
SEQUENCE# APPLIED

SQL> select destination, status, error from v$archive_dest;
DESTINATION STATUS ERROR
/arch/DGTEST VALID
DGTEST_DG2 VALID
/arch/DGTEST_STBY DEFERRED
INACTIVE
INACTIVE
. . .Please keep in mind that I have made this test environment as close as possible (I think) to our production environment.
One of the objectives is to confirm we can switchover and back in our production environment.
So if there is something seriously wrong with this environment and it is the same in our production environment, that would be one of my primary objectives to find out about.
Only significant difference is that we are also using DGBroker in production and I did create configuration yet until I got the switchover working manually first.Hi,
Follow This Steps:
How to Switchover from Primary to Standby Database?
MY Configuration:
RAC is configured on dcpdb1(node1) and dcpdb2(node2).
DB Name: dcpdb
db_unique_name: dcpdb
Instance Name: dcpdb1 on node1
Instance Name: dcpdb2 on node2
Active Data Guard is configured on drpdb1
DB Name: dcpdb
db_unique_name: drpdb
Instance Name: drpdb
Process:
On the primary server, check the latest archived redo log and force a log switch.
*########### Login dcpdb1 as Oracle user #########*
SQL> SELECT sequence#, first_time, next_time
FROM v$archived_log
ORDER BY next_time;
