Standby Database is Idle
HI There
I have configured Data Guard on oracle 10g (10.2.0.4) on Windows 2007 64 bits Server.
Both Primary DB and Standby DB are on same Server.
When I connect to my Primary DB, It is connected Normally as shown below.
Start --> Run --> CMD --> set oracle_sid=prmdb
c:\> sqlplus / as sysdba

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

Now Whenever I connect to my Standby DB, It connects to an Idle Instance. When I issue startup command
it displays a Message as shown below.
Start --> Run --> CMD --> set oracle_sid=stldb

Then I issue following commands to overcome this

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION
ERROR at line 1:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

SQL> ALTER DATABASE OPEN;
Database altered.
What is wrong with my Standby DB?
What to do to overcome these messages Permanently?
Why Standby DB is Not connected Normally instead of I have to start it?

you can check with
select process from v$managed_standby;There must be MRP0.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Database altered.
SQL> ALTER DATABASE OPEN;
Database altered.
Database opened read only mode.
Your Oracle Database version is 10.2.0. It means you can not start redo apply after open read only mode, too.
(Active Data guard able only 11g version)

Why Standby DB is Not connected Normally instead of I have to start it?I think, if you stop windows service, then this service automatically stopping standby database.
After start windows service, you must start database manually.

Error while mounting Standby database
Hi all,
I am getting ORA-01102: cannot mount database in EXCLUSIVE mode error when truying to mount the standby database.
SQL>alter database mount standby database ;
If anyone faced the same issue please guide me.
Thanks and Regards
Salih KMThis is script for Standby..
Primary Server Configuration
1.In the TNSNAMES.ORA of Primary DB add the entry of the Standby DB
IRCSSTDB(This is the service name in Primary DB to connect to Standby DB) =

2. There is no need to Make any Changes in the Listener.ora of PRIMARY DB
Keep LISTENER.ORA of Primary as it is
Copy Listener.ora from Primary DB to Standby DB and make following changes
Delete All the Extra Existing listeners.
(These Updations are for the STANDBY DB)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =

3.In the INIT.ORA of Primary DB add Following…
log_archive_dest_2 = "service=STBY optional/Mandatory scope=BOTH"
log_archive_dest_2 = Enable

2. Fal_client=standby1 (Service Name)
3. Fal_server=primary1 (Service Name)
Troubleshooting….
1. Check Init.ora of Primary DB
2. Try to open Standby Database in normal mode try to connect it with normal user from different Machine.
3.check *.logs file on Standby Database
4.Check v$archive_dest on Primary DB
5. lsnrctl services <listener name>….For Checking Listener, for service -
Problem Converting standby database from snapshot to physical
Any help willl be greatly appreciated...
I am trying to convert a standby database that is in "snapshot" mode back to "physical" standby and I am encountering problems in the process from the "DGMGRL" command line.
Both instances are on the same physical machine. Everything was working fine untill I tried to change the db from snapshot to physical. The DGMGRL starts the conversion process and is able to shutdown but when trying to restart the instance is fails and reports that the service is not defined.
Here is the issue I am facing:

So, here is the status now....with a little background...
After my original post, I started to read the manuals and I found the sql command to convert the database back from snapshot to physical standby (sb).
That worked fine and I had my snapshot sb back to physical sb.
So when you posted the suggestion, I already had my db in physical sb mode. I said no problem, I will convert it back to snapshot and then back again using dgmgrl instead of sql+
Well here is how my listener is configured now.
SID_LIST_I11G1 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = I11G1.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB_DGMGRL)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
Then using dgmgrl I tried to change the db from p-sb to s-sb and the results are not good....

Not sure if the following (notice the typo in the service name) in the parameter (log_archive_dest_2) definition on the standby d/b has anything to do with this. I did not get this error when I initially converted to s-sb.
also I checked all my session notes, I did not type the command to set this parameter on the standby d/b and so it was not a typo on my part. However, it seems to have come from the rman script supplied with the obe. This script is supposed to clone the primary d/b to a standby db and in the process replace the string /i11g1/ with /i11g1sb/.

I am tempted to start all over again, but I'd rather use this opportunity to debug this issue (as a learning exercise). I can always start from scratch. That brings up another Q: What do I need to do to blow away all traces of the stand by database (including all the archive logs etc...) keeping my primary intact. I'd also like to blow away all snapshot and archive logs for the primary as well. -
Manual Standby Database (10.2.0.2.0) on Windows 2003 R2
Hi,
We are setting up a standby database on a remote site for a simple oracle DB. As we already have a standby/master for another Oracle DB (from SAP) we want to stay as close as possible as what already exist.
For the SAP Oracle standby, we are copying manualy all archive to the stand by and apply them with brarchive. All is working fine.
For the new standby, we can not use brarchive as there is no SAP install on the standby but we stay with the "manual" copy of the archive from the master to the standby (using robocpy). It means all archive are on the standby (K:\oracle\oradata\archive).
The creation of the standby DB seems to be OK as i can open it, but i can't manage to apply de redo logs.
I'm quite new to oracle, so it's maybe a very basic issue, but i've already spent 3 days on it...
To start the DB, we lauch a bat script :
sqlplus /nolog @c:\backup\standby.sql
pause
the standby.sql:
connect /@TECDB01 as sysdba
startup nomount;
alter database mount standby database;
exit;
Then i connect to sqlplus and enter:
alter database recover managed standby database;
In another sqlplus session :
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
wich give me :
PROCESS STATUS THREAD# SEQUENCE# BLOCK# BLOCKS
ARCH CONNECTED 0 0 0 0
ARCH CONNECTED 0 0 0 0
MR(fg) WAIT_FOR_GAP 1 45400 0 0
RFS IDLE 0 0 0 0
The sequence 45400 seems to be ok regarding the time of the backup restored on the standby.
The archive is well on the server, but it won't apply it.

ORA-01666: control file is for a standby database -
Standby database not configure while keep database files in different place
Dear Friends ,
I have to successfully configured "PHYSICAL STANDBY DATABASE" within the TWO databases ("PRIM" and "STAN" Database) when I kept datafile, controlfile and redolog files in the same location (like, "/u01/app/oracle/oradata/prim" location .
In this successful configuration , I have to add the below two lines into the initprim.ora and initstan.ora both server respectively ...
initprim.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/stan','/u01/app/oracle/oradata/prim'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/stan','/u01/app/oracle/flash_recovery_area/prim'
initstan.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/prim','/u01/app/oracle/oradata/stan'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/prim','/u01/app/oracle/flash_recovery_area/stan'Now , in second scenario , I have to change Primary database server's datafile, controlfile and redolog file in the below folder :
controlfile --> "/u01/app/oracle/oradata/prim/ctrlfile"
redologfile --> "/u01/app/oracle/oradata/prim/redofile"
datafile --> "/u01/app/oracle/oradata/prim/datafile"
Similarly I have to create same folder in my STAN database server accordingly . and also add the above lines in same way :
initprim.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/stan','/u01/app/oracle/oradata/prim'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/stan','/u01/app/oracle/flash_recovery_area/prim'
initstan.ora:
========
DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/prim','/u01/app/oracle/oradata/stan'
LOG_FILE_NAME_CONVERT='/u01/app/oracle/flash_recovery_area/prim','/u01/app/oracle/flash_recovery_area/stan'Keeping the above situation when I run the below command in STAN database server :

And also no archivelogs are shifted from PRIM database server to STAN database server .
Would u plz suggest me , why I cannot configure Physical Standby Database when I keep my database fles in the separate location ?
help me plz ... ...Hi,
I'm missing the steps you took renaming/moving the files on the primary.
Since the location of datafiles is stored in the control file the controlfile of the standby might not know the new location yet.
I suggest you read this http://www.cs.bris.ac.uk/maintain/OracleDocs/server.816/a76995/standby.htm#23603 and see if that helps
Success,

Standby database failover flashback restart as standby gap 1-100
Hi,
I have setup a physical standby database for a 3 node RAC primary database and configured the database to run in MAXIMUM AVAILABILITY mode. Both the primary and standby databases use ASM for managing the IO. I have enabled FLASHBACK ON on both the databases.
I did failover to standby database with primary db SHUTDOWN for doing some testing. After testing is done, I flashbacked the (standby, currently primary)database to the point when it became primary and start it as standby again and the old primary as primary.
Following are the steps:
Failover steps
.Shutdown the primary database
To finisish the recovery at standby
SQL>alter database recover managed standby database finish;
To start as primary
SQL>alter database commit to switchover to primary;
do some DML on the new primary
SQL>flashback database to scn <standby_became_primary_scn>;
SQL>alter database create standby controlfile as '/backup/standby.ctl';
Changed the spfile to point control_files to '/backup/standby.ctl';
Restarted the standby db in mount mode and
created the required stanbdy logs on it.
Then issued

I have the following message in v$dataguard_status at standby db;

Could you please help me how to resolve the above error.
Thanks,
SreekanthSreekanth,
I think your steps are right on for your requirement, except instead of
alter database create standby controlfile as '/backup/standby.ctl';
you can do this:
ALTER DATABASE CONVERT TO PHYSICAL STANDBY;
(although perhaps it achieves the same thing internally but you don't need to repoint to new controlfile).
So far as the GAP - thread 1 sequence 1-100
Let me guess, your current sequences are probably well ahead of this reported gap?
If so, this is a bogus gap in a sense that your standby has long ago applied them, but for some reason standby controlfile gets a little confused and starts asking for them again.
I have had this issue and opened multiple TAR's with Oracle since 10.2.0.1, got a few patches and advises to upgrade, but still occasionally get it now in 10.2.0.3
I strongly believe this is related to combination of RAC (i.e. multiple threads of redo) and dataguard.
It is also pretty hard to reproduce (I have not figured out how to reproduce this reliably, if you have, let me know), so I can understand why Oracle has so far been unable to fix this.
Anyway, the workaround is to re-create standby controlfile with a copy generated on primary, and move it in place of the existing (and confused) controlfiles on standby. -

Firstly you can use "*select sequence#,first_time,next_time from v$archived_log order by sequence#;"* command in mount stage itself.No need to open the standby database in ready only mode.
No rows selected in mount stage also.
The V$ARCHIVED_LOG fixed view on the physical standby database shows all the archived redo log files received from the primary database.

no rows selected.
and No archived logs received from primary database to physical standby . i think here i wrongly configure parameter file.

When you do log switch on the primary are the archive logs getting transferred to the standby database???Is there some error in the alert log file in the primary database.
No..

ora-02778: Name given for the log directory is invalid
how can solve this problem . please replyHi user569791
you can configure standby to multiple destinations(up to 9 different destinations) and it is also possible to configure in same system also.
you need to create standby controlfile for Physical standby database.
check whether the standby instance run as a separate service and whether you
have an relevant entry in tnsnames.ora file. note that the db_name is same for both
sites but only the instance name differs.
Ensure that you have a
1.valid cold backup of datafiles,
2.valid standby controlfile
3.standby init parameters with db_file_name_convert and log_file_name_convert
parameters are valid
4. a special init parameter called lock_name_space need to be given when you configure standby on same site.
check all these condition and Try again.

Problem with data guard Creating a Physical Standby Database turorial
There is a tutorial of 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 primary database second for physical standby.
I have error on C. Creating the standby database over the network, action #6:
"On the standby system, set the ORACLE_SID environment variable to your <physical standby SID> (i.e. orclsby1) and start the instance in NOMOUNT mode with the text initialization parameter file."
When I try to connect to idle instance there is an error pops up:
C:\>sqlplus / as sysdba

ERROR:
ORA-12560: TNS:protocol adapter error
I'v checked listener and it is runned. There is no service for database because there is no database yet.
The question is did some one installed data guard configuration using this tutorial? Is there any errors in it? What should I do to finish this installation?On Windhose for every instance a service must have been created using the oradim command.
Oracle tutorials are usually Unix-centric, as Windhose is an odd man out, so they don't discuss that bit.
'Kindly do the needful' and create the service prior to starting the instance in nomount mode
Hint: oradim is documented and has a help=y clause.
IIRC there is an option in database control (in the maintenance part) which automates everything.

FYI : The primary and standby database are in sync.Hello;
The alert log is providing you with information. If you want more run this query :
select process,status,client_process,sequence# from v$managed_standby;You should see processes like ARCH, RFS and MRP0.
MRP will tell you if its applying log(s), waiting for a log, or if it thinks there's a gap.
