Table to check unregistered archive logfiles in standby database.

Hi,
Can you please let me know the table or query to check unregistered logfiles in standby database? (For 9i version)

I know we can check alert log to ensure if the archive logfile was registered. Just grep for PHYSICAL or the specific sequence number and see for ALTER DATABASE PHYSCIAL command.
grep PHYSICAL alert_$ORACLE_SID.log
grep <sequence> alert_$ORACLE_SID.log

as i know i need to register one by one is any other alternative.
Appreciated inputs.
Thanks

Changing the archive destination in standby database?

My DB is running on Oracle 9.2.0.6.0. I have data guard for my primary database.
Now i wanted to change the archive destination only standby database. What is the process? Any response or any link is appreicated. Thanks

The standby database wouldn't generate archivelogs until and unless it is opened (eg in a failover). So, although there is a definition for the log archive destination in the standby's init.ora / spfile, it is used only to read archivelogs shipped from the primary.
If you are talking of the destination that the primary's archivelogs are shipped to on the standby, technically once the archivelogs are applied on the standby, they are not required and can be deleted. You would be able to configure this.

Online Redolog Archiving on Logical Standby Databases!!

Hi,
Can I safely stop archiving on logical standby database? It has been inherited from primary database at the time of creation, but I don't see any reason why to keep it enabled while it's consuming unnecessary disk space on our server!!
Any body can give a valid reason to keep it enabled??
Thanks

hi
u dont need archiving on standby database as standby database reads archive files that come from primary database.its simply wastage of resource.stand by database was created from primary by taking a full backup.and to apply the archive files in case of failure u need atleast 1 backup of stand by database .and i assume u wont go for taking backup of standby database.
just worry about the archives of primary database.

Manually apply archived log to standby database.

Hi all,
I am working on oracle 10g EE(10.2.0.4).I am having a very difficult database switchover case in my hand.
1.> There are two database .one primary(prim) and another standby(standby).
2.> Initially both of them was configured as oracle data guard, where prim was primary and standby was standby using rman .(RMAN>duplicate target database for
standby dorecover).
3.>But the rate of generation of archivelog is very high( 20 archivelog per hour with 200mb each).
4.> So automatic shipping of archivelog has been disabled from primary.(log_archive_dest_state_2=defer and nullifying the value of log_archive_dest_2).
5> Now after a period of time archived logs are shipped to dr site manually and applied manually.(alter database recover automatic standby database;)
6.> Now there is a hardware problem occured at primary..it will take 72 hours to come up.
How can i use standby database as primary for that 72 hour.As archive log apply is manually done and parameters are being changed,can i switch over these two?
Is it possible to switchover and switch back these two database with such a configuration?

As of now you can perform failover your standby to primary database. you should have flashaback enabled, so you have to create a restore point.
Then it can be opened in read & write mode, So once you finished again you can go back to that point.
http://docs.oracle.com/cd/B19306_01/server.102/b14239/manage_ps.htm#i1017111
The above case applicable if you ready to loose, But it doesnt make sense. But in your case this doesnt work. Because once you start use of Standby as primary, there would be live/production data, which you need very much.
So there is lot of work to do.
You have to rebuild standby database and then switchover back to same location. So its a little trip work.
Have you enabled Dataguard Broker ?

You do not point to the standby database from your primary, in order to get the archivelogs transfered. You need to set at least the parameter LOG_ARCHIVE_DEST_2 like this:
SQL>alter system set LOG_ARCHIVE_DEST_2='SERVICE=stdby VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stdby';stdby has to be resolved by the tnsnames.ora on the primary server. Have a look here:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i67520
That explains all you need to do to create a physical standby briefly.

Hello
Most likely you don't have DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT in the standby INIT file.
Example here :
http://www.visi.com/~mseberg/rman/diff_database_duplicating.html
( see Step 4: Create an Initialization Parameter File for the Auxiliary Instance )
Example
LOG_FILE_NAME_CONVERT=('/u01/app/oracle/flash_recovery_area/RECOVER2', '/u01/app/oracle/flash_recovery_area/RECLONE')You can have more than one location as long as you add them in groups of two. (Before, After)
My duplicate notes are :
http://www.visi.com/~mseberg/duprman2.html
duplicate for standby fails with RMAN-05535 when path the same as primary [ID 783113.1]

Create ONLINE logfile in physical standby database

We have created a physical standby database with rman duplicate command on a remote server
"duplicate target database for standby dorecover nofilenamecheck"
When I see the standby server...Online logfiles are not created however its relevant entries are there in V$LOG and V$LOGFILE views.
I guess it is the default behaviour of duplicate command in RMAN and we can not specify LOGFILE clause when we create standby database.
Now the problem is we could not drop the online logfile on standby database since it's status is "CURRENT", "ACTIVE".
Since the ONLINE LOGFILE are not actually created , "ALTER DATABASE CLEAR LOGFILE GROUP " command returns with error as it could not find the file in the server.
So How we can drop the current/active online logfile and add new ones in standby db?

I'm assuming you have physical standby. Here are step I did in the past.
1) create a backup control file
2) bring the database back using the "recreate control file" it the trace file BUT you need to remove or comment out the line that has the corrupt or missing redo log file. And don't forget to add the tempfile after you recreate the controlfile
example:
alter database backup controlfile to trace;
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS FORCE LOGGING ARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
LOGFILE
GROUP 1 '/oracledata/orcl/redo01.log' SIZE 200M,
GROUP 2 '/oracledata/orcl/redo02.log' SIZE 200M,
GROUP 3 '/oracledata/orcl/redo03.log' SIZE 200M,
# GROUP 3 '/oracledata/orcl/redo03.log' SIZE 200M
-- STANDBY LOGFILE
-- GROUP 10 '/oracledata/orcl/redostdby04.log' SIZE 200M,
-- GROUP 11 '/oracledata/orcl/redostdby05.log' SIZE 200M
DATAFILE
'/oracledata/orcl/system01.dbf',
'/oracledata/orcl/undotbs01.dbf',
'/oracledata/orcl/sysaux01.dbf',
'/oracledata/orcl/users01.dbf'
CHARACTER SET WE8ISO8859P1
If you just want to add the standby redo log then using this command.
alter database add standby logfile
'/<your_path>/redostdby01.log' size 200M reuse,

How to apply archivelog with gap on standby database

Hi All,
Oracle Database version : 9.2.0.6
Following is my sequence of commands on standby database.
SQL>alter database mount standby database;
SQL> RECOVER AUTOMATIC STANDBY DATABASE UNTIL CHANGE n;

O/S-Error: (OS 2) The system cannot find the file specified.
I have check the last sequence# on standby database which is 19921. And I have archivelog starting from sequence# 20672 onwards. When I am trying to apply archive log starting from sequence# 20672 , it is searching for 'D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC' file and cancel the recovery. Please note that I don't have those missing archive on Primary server as well. So How can I apply the remaining archive log which I do have from 20672 onwards.
I hope I am not creating any confusion.
Thx in advance.

Hi Aijaz,
Thx for your answer. But my scenario is bit complex. I have checked my standby database status which is not running in recovery mode. I have tried to find archive_gap which is 0 on standby server. I am copying all archived log from primary to standby thru the script every 2 hour and appying them on standby. After applying, the script is removing all applied log files from primary as well as standby. So it is something like I have archivelog from 1,2,3,7,8,9,10. So 4,5 and 6 archivelog are missing which is required when I am trying to recover standby database. Also note that I want to apply 7,8,9,10. I will loose some data from those missing archive but I have cold back any way. I don't have those missing archivelog files(4,5 and 6) anywhere at all. So how can I recover standby database. I am using standby just for the backup purpose.
I hope my question is clear now.
Thx in advance

Backups on Physical standby database?

I am using dataguard and a physical standby database.How to assign backups on physical standby database to reduce the load on Primary database.
environment: windows
Database version:11.2.0.1.0
What are the pro and cons on assigning RMAN backups jobs to physical standby database?

Is it better to assign the RMAN backups on standby?i am using the RMAN catalog.Yes, Already mentioned to reduce contention on primary. You can register even standby.
Do i need to change the setting to backup archive logs from standby database? If i won't backup the archive logs on Primary the FRA will be full and i can't access it ?You can include even archive logs with your database backup.
How to assign the archive logs backups,full backup on standby database?Same script will work, Before that cancel MRP and after backup start MRP. That should be fine.
Recently i tested backup from standby and restore, Please see below log.

How standby database works

Hi!!
I have created standby database (testcat) for primary database (test) using Duplicate Command of RMAN on same server (windows XP) on Oracle 11.2 . I know how to create standby database But i don't know how and when standby database works. I checked init.ora file of standby database it contains all parameters prefixed with *. as follow
*.db_create_file_dest='F:\app\Administrator\oradata'
*.db_domain=''
*.db_recovery_file_dest='F:\app\Administrator\flash_recovery_area'
*.db_recovery_file_dest_size=10737418240
*.db_unique_name='testcat'
*.DB_NAME='test'
*.control_files="D:\APP\ORACLE\ORADATA\TESTCAT\CONTROLFILE\CONTROL_STAND1.CTL‘'
While init.ora file of primary database contains entries like
db_create_file_dest=F:\app\Administrator\oradata
db_recovery_file_dest=F:\app\Administrator\flash_recovery_area
db_recovery_file_dest_size=4039114752
control_files="F:\APP\ADMINISTRATOR\ORADATA\TEST\CONTROLFILE\O1_MF_8TXW6QN0_.CTL"
So I want to know is
          1. IS there any difference between parameter that start with .* and start without .*
          2. Can i set db_create_file_dest parameter in init.ora of standby database to another location.
           3. How redo log will be applied to standby database when I run ALTER DATABASE RECOVER ..... command
          4. where archived log files of standby database will stored?

1. Fetch Archive Log (FAL) Client :- It requests for archived redo log files from the primary site.
That means FAL Client is required (should exist) on standby database server. Am i right here?
FAL Client is Standby database, FAL Client requre archived log from FAL Server (primary, Cascading standby database ) for Gap Resolution.
2. Fetch Archive Log (FAL) Server:- It requests for archive redo logs from FAL Client (Standby database).That means FAL Server is required (should exist) on primary database server.
If yes then, why it is required because FAL Server request for archived redo logs from standby database while on other side standby database can not have redo logs as it runs in READ ONLY Access mode (So no DML and DDL) ?.
Also primary database will be always one step ahead in terms of archive logs than standby database and hence there is no need to request for archived logs from stanby. Am i right here?
Yes you are right. Primary is newer require archived log from standby. You asked and answered.

Regrading standby database in standard edition

hi gurus
i m facing problem in configuring standby database in standard edition windows 2008 .
os-windows 2008 standard
oracle 11gr2
i have copied files from primary n copied it to same location on standby...at that time database was in noarchivelog mode
then i made it archive n create standby controlfile...also i have created same service name thru oradim with mentioning pfile and same password as on primary
so it created pfile and password file...
i opened the database in nomount with pfile
then mount with standby controlfile it got mounted n the mode is automatically archivelog mode but as i didn't taken the same pfile of primary it didnt take the destinations as such n made archive in flash recovery area
now i m a bit confused how to apply archive..i copied some archive and placed it in flash rec area
i tried all options managed recovery.recover standby database,recover database until cancel
but all give error
please tell how i proceed..what shud b the right process in standby standard edition
if possible send me a good link for standby database creation in windows 2008 standard with how to ftp files with mget mput..
anyone if kindly provide a good link...wud b of great help
thanks all

on your standby database you can use:
set logsource path_to_archives
This will let Oracle know where the archive files are on the standby database.
Then you can apply the archives with:
recover standby database
Another option is to use Dbvisit Standby to automate the whole standby database (including creation) for you when you have Oracle Standard One or Oracle Standard Edition One.

STANDBY DATABASE 10 10g

I am in process of configuring the stand by database and I am getting the following error in standby database

ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: '/disk6/dbase/DSA/system01.dbf'

First step is to check the description of errors..
ORA-16004: backup database requires recovery
Cause: The control file is for a backup database which requires recovery, and cannot be opened for read-only access by this instance.
Action: Perform the necessary recovery and re-open for read-only access.
Check the DBWR trace file and alert_log file. Check the SCN applied on standby database. Find out any archivelog required to be applied...
Read 8.2 section..
