Standby database with ASM disks?

Has anyone successfully created a standby database when the primary database and the standby database are using ASM disks? If the answer is yes, how did you copy the files(database backup, control files, etc.) from the asm on primary to asm on standby?
Note: I am using 10gR2 on HP-UX but the copy part should be platform independent so however you did it should help me.

Hi d_carmichael2001,
I had done database migration from Non-asm to ASM for single instance by RMAN.
and i think mostly steps are same for create standby database on ASM.
Have a Look.......
1.create a ASM instance manually on new server.
2.Take a backup of Prod database and controlfile.
**backup of controlfile for Standby should be taken as
BACKUP CURRENT CONTROLFILE FOR STANDBY;
Backup database cmd will be same as Backup database plus archivelog;
3. create standby database by using following cmd and set necessary parameter before execute it
Diskgroup for standby should be define in standby spfile's.
**Standby database should be in nomount stange
**connect as % rman TARGET / AUXILIARY SYS/sys_pwd@sbdb1
Use
DUPLICATE TARGET DATABASE FOR STANDBY ;
This command will copy the datafiles, archived redo log files and standby control file in the backup set to the standby database's storage area.
Thanks

What are the differences of creating a physical standby database with ASM?

I want to create a physical standby database for my 10g(10.2.0.1) database. But it is using ASM. Is it possible to create a standby database for a database using ASM?
What are the differences of creating a physical standby database with ASM?

tell us what your research shows and we'll try to
validate it. I am simulating Oracle ASM on a PC and I want to try
DataGuard on it now. So I am trying to create DataGuard
on an ASM system. The purpose is only learning and test.That's telling us how you are researching, not what you have observed.
Your research could have included looking at the documetation, and you might have found http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/scenarios.htm#sthref1642
which discusses exactly what you are looking for.

Logical Standby Database with 10g+ASM on both sides??

Hi out there,
is there a known way to establish a logical standby database on 10g, if both
sides are running with an ASM setup?
I've tried to create one out of a physical standby database (which is set up
and running w/o any problems), like a book suggested me to do.
The procedure was:
1. switch on supplemental logging
2. prepare initiation parameters (for archive logging etc.) on both sides for
logical stb.
3. shut down the phyiscal standby
4. alter database create logical standby controlfile as '<path>'; on the
primary, transfer the controlfile to the standby db. Here I had to use RMAN
to copy the controlfile into the ASM System, and modify the initfile/spfile
in order to use the controlfile. No problem so far.
5. mount the standby database, alter database recover managed standby database
disconnect; -> At this point, the alert log complained about non-available
datafiles.
6. alter database activate standby database; --> fails ("needs recovery") due
to last point.
The trouble is, the controlfile created at point 4 cointains wrong paths to
the datafiles. Since I can not have the same disk group name on the standby
system, and since ASM renames the stored datafiles by its own, the complaints
of point 5 are comprehensible, but nevertheless annoying.
I tried to backup a controlfile to trace and change the paths, but at after
mounting the standby with this controlfile and proceeding at point 5, the
system says "<path> is not a standby controlfile"
Is there a different way of creating a "Logical Standby Database with 10g+ASM
on both sides"? Metalink said nothing about LogStby and ASM.
Best regards and thanks in advance,
Martin

I'm not sure if this will work but try:
1. create trace control file (you did it)
2. change paths (you did it)
3. recrate control file (you did it)
... there was error occured during mount before
so mount database (not as standby)
4. create standby control file (from recreated control file)
5. shutdown instance, replace control file with new standby control file or replace the control filename in parameter file.
6. mount as standby
What happend?
Update: Tested on my side and it has worked fine... How about you?

How to create database with ASM

HI
How to create database with ASM?
I install vmware workstation on window XP .On virtual machine install Linux 5 enterprise (Oracle) install.
I install oracle DB software only. Also make 3 disk for ASM .
1 -- When I want to install oracle DB with ASM . In this process candidate disks not show . Why?
How I can see disks ..
so I simple install oracle DB software only.
2 -- Now I want to create database with ASM by DBCA .
What process I will follow ?
Please guide me
Thanks

Hi
Steps to create database with ASM.
1.Install oracle binary with active CRS(For single node installation CRS is activated when you run root.sh) .
2.Create disk without file ssytem.
3.Assign disk to raw .
4.Change owner and permission to raw devices.
5.Configure ASM manually or USing DBCA.
Manually ASM Configuration.
a.Create initialization parameter file and password file.
b.Mandatory parameter is "instance_type=asm" as per your need configure rest of parameter like db_cache_size,large_pool_size,processes,remote_login_passwordfile,shared_pool_size etc..
c.To discover disk configure "asm_diskstring=/dev/raw/raw*"
Using DBCA to configure ASM.
1.In storage type section choose ASM.It will ask for password of sysdba in 10g.
2.ASM configuration window will open -> here it create disk group -> it shows all available ASM candidate disk automatical -> choose normal redundancy,external redundancy or high redundancy.
ASM disk also can be conbfigured with ASMLIB .
If ASM disk is configured you can start asm instance in nomount state and query to v$asm_disk to see all candidate disk.V$asm_disk only shows disk which is configured in asm_diskstrings.
Hope this will help U,
Tinku

Installing Oracle Database with ASM on Oracle VM for SPARC

We're installing Solaris 11 and Oracle VM for SPARC so we can install Oracle Database with ASM. There is a requirement when creating the database that the raw disk have an owner that is the same as the database. Everytime we try to change the owner it will always show that the owner is root.
Any ideas?

Hi
Please let me know from where you are allocating ASM raw disks for the guest domain.
i hope you are changing the disk permissions using chown -R
Also confirm the permission using command # ls -IL /dev/rdsk

SQL exception during creation of a physical standby database with EM

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Standby Database with Standard Edition

Hi All,
I'm attempting to setup a Standby database with Oracle 10g Standard Edition. I must manually copy over the archive logs to my Standby database server because i'm using Standard Edition.
Once my primary database archive logs have been copied over to the standby location shouldn't the database automatically apply those archive logs? I have issued the "alter database recover managed standby database disconnect from session" so my understanding is that it is in recovery mode and shoudl be finding the archive logs to apply. Can anyone confirm that this configuration should work with Standard Edition and perhaps point me in the right direction, which parameters in the init file to check, to get my standby database to apply these archive logs automatically.
Thanks,

To quickly determine the level of synchronization for the standby database, issue the following query on the physical standby database:
SQL> SELECT ARCHIVED_THREAD#, ARCHIVED_SEQ#, APPLIED_THREAD#, APPLIED_SEQ#
2> FROM V$ARCHIVE_DEST_STATUS;
ARCHIVED_THREAD# ARCHIVED_SEQ# APPLIED_THREAD# APPLIED_SEQ#

Looks like very difficult and inform you mgmt about the drawbacks of running olderv ersions
may be you can try something like this but i dont know whether it is supported or not

Standby Database with RMAN on ASM

Hi,
I am using redhat Linux AS 4 and my database is 10.2.0.1. This database used ASM for storage of data files, control files, online redo logs. Flash recovery area is also configured in the ASM.
I want to create a physical standby database on a different machine by using RMAN. Can someone kindly point me to some easy to follow document? I have scoured the oracle docs, but am more confused than ever.
regards

DB_UNIQUE_NAME vs DB_NAME in standby databases of ASM file systems

Question : Do we need to have the db_unique_name paramter set differently in standby database compared to db_name in standby .
Problem we are facing :
Here is the little background
Primary Server     : SERVER1
db_name          : VENKAT
db_unique_name     : VENKAT
Standby server     : SERVER2
db_name          : VENKAT
db_unique_name     : VENKAT_stb
Sever          : Linux
Database Version: 11.20.3
File system type: ASM ( 11.2.0.3)
stanby type     : Physical
Disk group names: Identical on both primary and standby servers
Data          : +DATA_OP01027_128
FRA          : +FRA_VENKAT_128
How datafiles are layed out on primary server:
sample datafile name location : +DATA_VENKAT_128/VENKAT/datafile/venkat.277.789579565
How standby was build : using Active duplicte command
Once we have the standby database build we have the datafiles created under this location
Sample datafile name location on standby server : +DATA_VENKAT_128/VENKAT_stb/datafile/venkat.280.789579597
with this we have learnt that the directory VENKAT_stb is getting created in standby ASM off the db_unique_name that
was given in the database , we have not seen this issue in the normal file system even we are using db_unique_name different that
the db_name in standby database .
Can you please help us how we can prevent this situation of having datafiles getting created under differnt direction in standby compared to prod.
Can you also let us know what impacts we might be having if we don't specify the db_unique_name different than db_name in standby database.
Hope this explains the problem what we are facing currently .
What steps i follwed to fix this issues :
I have db_unique_name set to the same name as db_name and when i did the restore all datafiles are in the identical location to prod standby server .
Note : We do fully understand the need for having the db_unique_name set different to db_name in standby db in standby and primary db's are residing on the same physical server .
Thanks
Venkat

first of all, this is not an issue or problem
works as intended
Question : Do we need to have the db_unique_name paramter set differently in standby database compared to db_name in standby .yes
Sample datafile name location on standby server : +DATA_VENKAT_128/VENKAT_stb/datafile/venkat.280.789579597
with this we have learnt that the directory VENKAT_stb is getting created in standby ASM off the db_unique_name that
was given in the database , we have not seen this issue in the normal file system even we are using db_unique_name different that
the db_name in standby database .
Can you please help us how we can prevent this situation of having datafiles getting created under differnt direction in standby compared to prod.well, dont use OMF then
OMF format for datafiles in ASM is: +DISKGROUP/DB_UNIQUE_NAME/DATAFILE/TABLESPACE_NAME.FILE.INCARNATION
datafiles will be created this way no matter what you do
the difference is, that if you dont use OMF, there will be an alias created referencing the file, with the path you gave
for example:
OMF:
create tablespace test size 10M;
a datafile is created: +DATA_VENKAT_128/VENKAT/DATAFILE/test.280.789581212 (i wrote some random numbers here)
non-OMF:
create tablespace test datafile '+DATA_VENKAT_128/dummy/test01.dbf' size 10M;
what actually happens:
a datafile is created: +DATA_VENKAT_128/VENKAT/DATAFILE/test.280.789581212 (i wrote some random numbers here)
and an ASM alias is created: +DATA_VENKAT_128/dummy/test01.dbf
and this alias is used by the database
while OMF files have their specified path format, and their path (db_unique_name) and even name (numbers at the end) will change when duplicated, aliases dont necessarily do this
however this is just extra work and administration, OMF is your friend

Creating Standby Database from ASM Databse none ASM

I have ASM RAC database running on Solaris 10. I want to take a backup with RMAN and move the Backup to none ASM on other Stand alone server. I want to use this none ASM backup database to create Standby Database for Test purpose. Is it doable? If it is doable can you answer following questions?
What command should I use with RMAN to take a full backup and move it to none ASM platform?
Thank you

Well, the answer is most likely yes, but first need to confirm
- Do you want a physical or logical standby?
- Will the standby run on the same platform , i.e. also Solaris 10?
- What version of database ? It is much easier in 11g.

Standby database with ASM disks?
