Physical standby without ALTER DATABASE FORCE LOGGING

Hi,
Is it possible to use physical standby database without executing ALTER DATABASE FORCE LOGGING on primary side?
Can I use alter tablespace force logginng instead?
I want to have one tablespace with nologging option turned on to reduce redo traffic for some operations.
I can not check this because I don`t have enough servers to build standby configuration.

Physical standby without dataguard

Naive question.
I am going thru metalink note (374069.1) on how to create a physical standby. In that note, they didn't mention data guard stuff. Am I to assume that physical standby without dataguard can be created?
Thanks.

It might appears to be easy to create psuedo standy but you will have hardtime to simulate the automatic archive log apply and gap resolve.
Plus the level of data availability provided by self-managed standby can't come close to Data Guard can offer.
With Data Guard you can almost get zero data loss between Primary and Standy, depends on your redo logfile size there could be many data in online redo logs.

ALTER DATABSE FORCE LOGGING

hi,
while creating standby database why should we start the database in force logging mode? what the use of it? what does it do?
With Regards
Boo

Synchorinization between primary and secondary database is done through archive logs. It would be safe to force primary database to log everything, so that it reflects to secondary database. That is the reason we have to force logging.

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..

Problem While Creating Physical Standby Using RMAN

Hi Guru's
May be this incidence you all face while creating physical standby DB. I try to create Physical standby database Using RMAN Duplicate Command from one server
(pri machine) to Standby Machine.
The steps i followed to create the above are as follows:
Step 1:- Enable Forced Logging
SQL> ALTER DATABASE FORCE LOGGING;
Step 2:- Configure a Standby Redo Log
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 10
2> ('/oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500M;
Step 3:- Set Primary Database Initialization Parameters
SQL> create pfile='?/dbs/pfileorcl.ora' from spfile;
Edit the pfile to add the standby parameters, here shown:
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:- Enable Archiving
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE OPEN;
Step 5:- Setup tnsnames for standby database
This should be done on primary database by altering tnsnames.ora or using NetCA command, and create it by the name orcldr
orcldr =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby-svr)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcldr)
Step 6:- Backup database and copy it to standby
This backup script should be run on primary and copied to standby on the same mount point, running this scripts using RMAN, all files under /rman_backup should be copied to /rman_backup on standby server.
$rman target /
RMAN> run
allocate channel c1 type disk;
allocate channel c2 type disk;
backup database format '/rman_backup/%U';
backup archivelog all format '/rman_backup /%U';
backup current controlfile for standby format '/rman_backup/%U';
Step 7:- Standby Database Steps
Installing Oracle Software
This should be same release and patchset with exactly same ORACLE_HOME mount point.
Setting Up listener
Create and start a listener on standby database using NetCA, or creating listener.ora in $ORACLE_HOME/network/admin
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = standby-svr)(PORT = 1521))
Step 8:- Set Standby Database Initialization Parameters
Copying the pfile created in primary database and renames it to initorcldr.ora, and changes these parameters:
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:- Setup tnsnames for primary database
This should be done on standby database by altering tnsnames.ora or using NetCA command, and create it by 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 over to the Standby site. The sys password must be identical on both sites. Copy orapworcl to $ORACLE_HOME/dbs and rename file to orapworcldr
Step 11:- Create mount points for Oracle
Mount point should be created on standby server with the same convention used in primary, this includes the location for controlfiles, redo logs, datafiles, archive log destination and alert logs.
$ mkdir -p /u01/app/oracle/oradata/orcl/
$ mkdir -p /u01/app/oracle/flash_recovery_area/
$ mkdir -p /u01/app/oracle/admin/orcl/adump
$ mkdir -p /u01/app/oracle/admin/orcl/bdump
$ mkdir -p /u01/app/oracle/admin/orcl/cdump
$ mkdir -p /u01/app/oracle/admin/orcl/udump
Step 12:- Use RMAN to restore backup and setup standby
Connect to RMAN and execute the following command to create standby database, this should be performed on standby server after copying backup and setting tnsnames.
$ export ORACLE_SID=orcldr
$ rman target sys/tiger@orcl auxiliary sys/tiger@orcldr
RMAN> duplicate target database for standby dorecover;
Here i am getting problem as :
While trying to connect to traget database and auxiliary database i notice that when RMAN is connect to both databases it shows
orcl ( DBID xyz)
orcl (not mounted)
Here in my view the second database must be standby database name or auxiiary db name is standby db name which in my case is orcldr
after this issue i am facing the second issues as :
in command
duplicate target database for standby dorecover;
After modifying the command to
RMAN> duplicate target database to "standby";
rman-05520 database name mismatch
Can u please let me know where i am mistaking

ok for pri:
db_name=orcl
db_unique_name=orcl
for standby:
db_name=orcl
db_unique_name=sbyorcl ( i change orcldr to sbyorcl later)for new testing
but now what i am getting on

Physical standby database

My physical standby database is on Win 2003 server, Oracle version is 9.2.0.3.
Windows team asked me to shutdown the standby database and i did the same. After server reboot i put the standby in managed recovery mode but logs were not shipping even though i gave log switches at the primary side.
I executed the below command
startup nomount
alter database mount standby database;
alter database recover managed standby database disconnect from session;
I again bounced the standby database but this time i gave
recover managed standby database disconnect from session;
Instead of alter database recover managed...
Below are the logs from alert log file of the primary database

could some one let me know the difference between specifying alter database and not specifying alter database???

There's no difference, two ways to reach the same target. 'Recover' (without alter database) is listed as pure sqlplus statement and 'alter database recover' an option of the 'alter database' statement.

How to apply Oracle patch when physical standby database in place

Dear All,
I want to apply Oracle patchset 8 on 10.2.0.5 when physical standby database in place. What are the steps for Primary site and for standby site.
Thanks in advance
Kamran Laeeq

Hi Kamran,
You will not upgrade or patch the standby database by importing offline redologs. On the contrary, there is a procedure to do this. Please note that you will not transitiate the role from standby to primary or startup the database. You will just startup the database by executing "startup mount" and "startup upgrade", during the upgrade. It means that you will not change database role standby to primary and you will be able to continue to the log shipment after the respective upgrade.
But, it is very important that you should stop the log shipment and apply all the offline redologs, before the upgrade. Technically, you can import offline redologs after the upgrade, by changing "compatibility" parameter in oracle, but regarding to my experiences it may cause some problems after you transitiate the role from standby to primary.
In short;
In order to stop log shipment, at the primary site;
alter system set log_archive_dest_state_2=defer;
In order to import all the offline redologs without a delay, at the standby site;
alter database recover managed standby database cancel;
alter database recover managed standby database nodelay disconnect from session;
I hope that I clarified the issue,
Best regards,
Orkun Gedik

Physical Standby Online Redo log files,

Hi,
I'm trying to create a physical standby database (10.2.0.3). I'm a little confused about the requirement for online redo logs on the standby.
in my standby alert log I get the following when I issue:
SQL> alter database recover managed standby database disconnect from session
"ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/appl/oradata/prod/prod_1_redo_01_02.log'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3"
/appl/oradata/prod/prod_1_redo_01_02.log is the path to the location of the online redo logs on the production system. This file does not exist on the standby filesystem so the error is correct.
I assume that it gets this information from the standby control file I created on the production system and copied over to the standby.
Do I need to copy the online redo logs from the primary over to the standby site or do I need to create online redo logs on the standby?
Does the standby need to have redo log files?
I'm not talking about 'standby log files' of the type created using 'alter database add standby log file'. I've not got that far yet.
I just need to establish if a physical standby requires online redo log files?
Thanks in advance,
user234564

I wanted to update this thread since I've been dealing with the exact same errors. The basic question is: "does a physical standby need the online redo logs?"
Answer: Not really, until one wants to switchover or failover (and become a primary database). Furthermore, whenever the MRP process is started, Oracle prepares for a possible switchover/failover by "clearing" the online redo logs (MetaLink note# 352879.1). It is not a big deal, since Oracle will build the actual redo files when the "alter database open resetlogs" is accomplished during a "role transition."
In our situation, we have decided to use our standby for nightly exports. We stop MRP, open the database read-only, then restart MRP. We built these standby DBs with RMAN. The RMAN duplicate process will not build the online redo log files until the database is opened for read/write (with resetlogs). However, we haven't had a need for read/write (i.e. a switchover).
Thus, every morning we have been getting the same errors that "user234564" posted above. At first the errors seemed scary, then we realized they were just a nusiance. In order to clean things up, all I did was just "cp" our stanby redo logs (SRL) into our online redo directories ensuring the names matched what was in v$logfile. When I restarted MRP, the alert log clearly showed Oracle clearing these "newly found" online redo logs.

Alter database recover to logical standby is hanging

Hi,
when I try to convert my physical standby to logical standby using
alter database recover to logical standby STANDBYL;
the command just hangs
I have seen the usual hit on this which is to create the Redo Dictionary on the Primary using
execute dbms_logstdby.build;
which I did but the alter database command still keeps hanging on my Standby
Any ideas,
thanks
Jim

Hello;
Does your Standby alert log have any lines like this:
RECOVER TO LOGICAL ...
If yes look for the message ( after this )
Starting datafile conversion
and post any errors or warnings you have.

"Alter Database" command in Database Standby

Hi community.
I have the following situation:
I've ASE 15.7 CE SP121 in two enviroments: System Production and System Standby. The Standby is maintained with load of dump transaction generated in production every 10 minutes.
Now I need increase a database in data portion in 100GB. I know that I must make this in each enviroment (Production and Standby), also I know that I can execute alter database command while the database in the System Standby is offline.
The process that I make is:
Stop dump transaction in production.
Stop Load transaction in Standby.
Alter database "on" in Production. Result is Sucessfull.
Alter database "on" in Standby. Result is error:
In this step, I receipt the following error:
The database DBUSER is in the middle of a load sequence. Altering it will not let you load other transaction dumps in the dump-set. If you still prefer to do it please use OVERRIDE option.
In this situation I have that put online database and increase the size. Obiously, I can't load more dump transaction and I should generate a full dump database in production, load this dump in standby and load dump transations after to load of dump database (full).
I simulate my situation in a enviorement of test with pubs3 and then of load the last dump transaction, I can do alter database in my DB standby without problems and after of this process I continue load dump transaction.
I don't understand why receipt this error?
Any recomendation?
Thanks!
Cristian Lopez.

I can't recall trying to extend an offline database so what I'd probably do (short of waiting for a definitive answer from someone @ SAP/Sybase ... either here in the forum or from tech support) ...
1 - Assuming you have to perform a full database dump/load after issuing 'alter database', decide on a good time to perform the full database dump/load and then ...
2 - follow your steps (above) and then try restarting the log dump/load and ...
3a - if the log dump/load succeeds ... you've got nothing else to do
3b - if the log dump/load fails, then proceed with the full database dump/load

ERROR in creating a Physical Standby Database

Hello all,
I am using a Windows Vista O/S and Oracle 10g Enterprise Edition. Both my primary and standby are on the same host. Created standby instance using oradim.
I have followed instruction in the documentation and created a manual standby database.
primary database is 'orcl'
standby database is 'stby'
My primary archives is not being copied to the the stby location as confirmed by an error shown:

OK that solves part of the problem.
Now this is very strange error I am getting. The path it looks to recover from archive is not right, it should point as per my actual archive log dest. See below.
