Setup of Standby on Maxdb

Dear All,
I have to setup DR site using maxdb on Redhat Linux 5.4.
On Primary Server and and Standby Server
Please advice Hostname Should be same.
Steps i will follow to setup DR site.
1.Backup copy from Production server will be restore on Target Server using Homogeneous System using Recovery with initialization.
2.Once my system will be up and running i will start put my standby Server DB in admin mode.And will apply logs using log shipping from the primary server.
Please advice me for the hostname as to start SAP in standby hostname should be same as Primary.
Regards,
Sahil

> Means once we are putting our standby online system and after that again i am putting my db in admin mode.Than log shipping will not work.?
correct, it won't. Once the database is online it produces its own logs and you can't apply any other ones.
> Please advice for the hostname also .Is it mandatory to have hostname to be same on primary and standby server.
For log shippings sake you don't need the same hostname. It depends how you plan to get it into production.

Setup of standby with log shipping

Hello list,
I want to setup an standby database on a different server, based on regularly complete/incremental/log backups.
In the past we run this scenario (via bash scripts):
- complete backup (once a day)
- incremental backups (every 30 minutes)
- cold incremental backup in the case of normal switching from live to standby server
This scenario works fine for the 2-3 situations, where we have to switch between the servers.
Now I want to change this to a combination to (mix of bash and perl scripts):
- complete backup (once a week/month)
- incremental backup (once a day)
- log backups (every <n> minutes)
according to the maxdb documentation and due to the fact, that we have configured autolog on and this way generate about on log backup every hour.
In various tests I have found a solution, where I use a complete backup for initialization and then regularly restore the log backups from the original db to the standby db.
Here an example:
a) db_admin
   db_connect
   db_activate RECOVER <complete media> DATA
b) db_admin
   db_connect
   recover_start <log media> LOG 001
c) db_admin
   db_connect
   recover_start <log media> LOG 001
   recover_replace <log media> "<location of log media>" 002
d) db_admin
   db_connect
   recover_start <log media> LOG 002
   recover_replace <log media> "<location of log media>" 003
and so on ...
Here are my questions:
1. Is it correct, that I have to restore the last successful restored log (if not the first) from the previous session with "recover_start", before I can restore the next log with "recover_replace" in a new session?
2. Can't I mix the restoring of incremental and log backups in this way: log001, incremental data, log002, ...? In my tests I was able to restore the incremental data direct after the complete data, but not between the log backups.
3. Can I avoid the state change to OFFLINE after a log restore?
I have read various documentations about this subject, but didn't find detailed descriptions about the concrete interactions between these commands, when using them in shell or perl scripts, which are executed regularly.
Maybe somebody has developed something similar to this. I've seen some approaches from others, but none of them seems to cover completely the scenario above.

Thomas

Yes, that's correct. As soon as you leave the restore session, you have to provide a 'overlap' of log information so that the recovery can continue.
> 2. Can't I mix the restoring of incremental and log backups in this way: log001, incremental data, log002, ...? In my tests I was able to restore the incremental data direct after the complete data, but not between the log backups.
No, that's not possible. After you've recovered some log-information the incremental backup cannot be appliead as a "delta" to the data are anymore as the data area has already changed.
> 3. Can I avoid the state change to OFFLINE after a log restore?
Of course - don't use recover_cancel
As soon as you stop the recovery, the database is stopped - no way around this.
There are some 3rd party tools available for this, like LIBELLE.

Error while trying to setup a standby database.

While tring to setup a standby database (with version 8.1.7.0.0) i am running the command:
recover managed standby database timeout 20;
Here is the errors i'm getting:
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/data/syndicate/standby/system/dup75_system01.dbf'
ORA-16016: archived log for thread 1 sequence# 6518 unavailable
Although it says that file 1 was not restored from sufficiently old backup I've copied all the datafiles from the primary database at once - using a script.
The archived log sequence it asks for is non-existant - the last one i have is # 6517.
Thank you guys in advance for any ideas.

I am having the same problem as you are when I am applying the current logs after successfully mounting standby database as seen below:
SVRMGR> alter database mount standby database;
Statement processed.
SVRMGR> recover standby database ;

ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: 'C:\ORACLE\ORADATA\STANDBY\SYSTEM01.DBF'
SVRMGR>
Just before copying the datafiles from the primary database I did the following:
Connected to the primary database:
1. alter database create standby controlfile as .....
2. alter system switch logfile
3. shutdown normal
4. took a cold backup (including archived redo logs)
Copied the data files, redolog files, archived redo logs and standby controlfile to standby database:
1. made copies of standby controlfile over current standby ones.
2. startup nomount (the standby database)
3. alter database mount standby database;
4. recover standby database;
That's when it asks for an archived redo log that does'nt exist and when I enter cancel, that's when I get the above error?
Am I not applying the latest redo logs to the latest cold backup of the primary database?
Your help would be much appreciated!

Initial setup for standby database - doubts ??

Hi,
While creating a physical standby database from a primary database what is the initial setup in case of the standby database which will be created.
1.Is it that I will only install the oracle with no starter database and then continue with the steps for creating standby database.
2. The SID has to be the same for both the database or can it be different.
Waiting for your answer.

Failed to add hot standby instances in liveCache Hotstandby setup

Hi All,
I am trying to setup Hot Standby between two HP-UX IA64 hosts and facing few issues. Given below are the setup details.
Hosts: HP-UX IA64 B.11.31
liveCache version: 7.7.06.16
Storage: EMC Symmetrix
maxDB Database Manager: 7.6.06.04
These are the steps I did using maxDB GUI
1. Added primary server (i.e. MASTER).
2. Made it online to validate the setup.
3. Made it offline, so that Hot Standby System can be enabled.
4. Enabled the Hot Standby System, and created a virtual server name entry.
5. Made the primary online, so that standby instances can be added.
6. Tried adding Hot Standby instances and saw a pop-up message with following error.
"-24994 Runtime environment error [hss_addstandby ...]; 20090, Check knldiag! Kernel exited with '0' before reaching ADMIN state"

You may try to load the symmetrix shared library for PA-RISC platform but you are on IA64. Shared libraries on IA64 have the extension ".so". There is an "emulator" (ARIES) on IA64 to run PA-RISC binaries - but since the database you run is IA64 it can't load a PA-RISC shared library.
What do you get when you run
file /usr/symcli/shlib/apps/SAP/libemcslc.sl
However, this is just a guess.

Can i setup standby between the DBs in different servers of different OS

Dear All,
1) Can i set up the standby database between Linux server and Windows server?
2) Can i setup the standby on a single server?
Thanks
Mahi

1. Only if the endian format is supported on both platforms and if the version is 10g
2. yes, but that defies the concept of disaster recovery.

Standby setup in 11g R2 RAC to single node

Hi,
How can we setup 11gR2 Standby Setup : Primary Database 2 Node RAC to Standalone Standby Database

ashish wrote:
Hi,
Our requirement is to create single node standby of a 11g R2 RAC 2 node database.To implement there is not much changes in functionality of dataguard, Except some new features like
1) Active dataguard
-- Where you can run MRP even in open status, so that it can be only readable.
2) password file on standby should not be created, it should copy from primary and rename it.
3) from 11g you can perform duplicate from active database without backup.

Switching between Primary and Standby database

Hi,
I managed to setup a standby database that is updated by the primary db either when doing a log file switch or when changing the role of the primary db to standby.
Now I want to put the standby database (that was in primary role for a short period) back into its standby role. I entered
"Alter database commit to switchover to physical standby with session shutdown;"
The archived redo logs as well as the control file are updated on the primary database (which was in standby role for the same short period). When I enter
"Alter database commit to switchover to primary" I am receiving the following error message:
SQL> alter database commit to switchover to primary;
alter database commit to switchover to primary
ERROR at line 1:
ORA-16139: media recovery required
After issuing the recovery statement I get this message:
SQL> recover database
ORA-00283: recovery session canceled due to errors
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done
At the same time this log entry is written into the alert log:
Database not available for switchover
End-Of-REDO archived log file has been received
Archived log files detected beyond End-Of-REDO
Incomplete recovery SCN:0:962365 archive SCN:0:977340
Switchover: Media recovery required - standby not in limbo
ORA-16139 signalled during: alter database commit to switchover to primary...
But when I try to use the BACKUP CONTROLFILE statement during recovery I get this error message:
SQL> recover database using backup controlfile;
ORA-00283: recovery session canceled due to errors
ORA-01666: control file is for a standby database
Although being quite a newbie it's obvious that the primary database (which was standby for a short period) is worried that there are older archived redo logs than online logs. I guess this happens because of the log_archive_dest definition on the standby database :
*.LOG_ARCHIVE_DEST_3='SERVICE=ORAMPPRD REOPEN=60 MAX_FAILURE=3 LGWR SYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=ORAMPPRD'
Changes are applied immediately and only written to the archive.
But how can it be managed that the online redo logs on the primary system are also updated when switching back from standby ???
Thanks,
Philipp.

Thanks, it's working now.
I think it's important to explizitely follow the steps to switchover standby and primary for it to work. I maybe shutdown the standby to early.
Cheers,
Philipp.

Error while Creating a Logical Standby Database

Dears
I setup physical standby db. Now trying to convert it to logical standby db by following this link:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#i92346
When i issue this statement:

you seems to have issues with your setting. For instance see the controlfile parameter.
*.control_files='F:\orakill/\control01.ctl','F:\orakill/\control02.ctl','F:\oradata/orakill/\control03.ctl'
also check whatever directory given actually exist in the server.

Question regarding removal of physical standby database?

We are running a 2 node rac cluster on linux itanium and we have setup one physical standby server. We did not use the data guard broker to setup the standby database we simply set 2 parameters log_archive_config and log_archive_dest_2.
We now are looking to remove the physical standby server and I see that the 2 parameters are dynamic so I was trying to find out if it is as simple as running the alter system comands to reove the 2 parameters?
I gues my real question is more about the syntax of removing the parameters?
Would this syntax be correct?
alter system set log_archive_config='' scope=both sid='*';
alter system set log_archive_dest_2='' scope=both sid='*';
and does it make a difference which parameter is removed first?
Thanks I appreciate any help.

the standby system is also a 2 node cluster but only one of the nodes has the instance up in a mount state running in recover mode and the other instance is simply shutdown.
Thanks.

Logical standby database problem
