Copy Orace file-system database to ASM

Hi,
We are planning to use ASM and migrate of file-system database
How do you move/copy oracle datafiles,logfiles,controlfiles,*.dbf to ASM?
The docs said ASM does not allow OS copy commands :(
Thanks a lot

Thanks a lot Hussein, Arnoud :) I like those docs very short/summarized and easy to understand, unlike other oracle manuals which gives you lots of choices/platforms/versions/ and confusion mixed in one.
By the way I am planning to install a new set of 64-bit EBS R12 on ASM/RAC and leave alone our EBS R12 32bit(filesytem) running. I dont like to migrate it because it so critical
and sensitive to touch.
Just a little clarification :).....When I run EBS R12 installer (database tier side) It ask for
home directories like: /u01/app/orace
My question is I want my database files (.dbf) to be directed to an ASM disk
How do I input it in the Rapidwiz installer? I did not see any options there to use ASM disk.
Thanks again

ECC6 EHP2 (ABAP+Java) system copy using file system copy

Hello Experts,
I have a question around system copy method for a dual stack ECC6 EHP2 system.
We are planning to take full file system backup of this entire ECC6 EHP2 dual stack system and throw it on a completely new hardware with new host name but same SID. We are also planning to do a host renaming in instance profiles and re-building the control files in target system after we finish the file system restore.
Is this method supported in SAP ? Or we strictly have to use SAPinst to do export and import method. In any case our source and target platform is not going to chance as per our scenario.
Any suggestions will be greatly appreciated.
Thanks,
Harshal

> Thanks for the quick response. Is their any document that says it is not supported ? Because of no proper document that says no to do it, client want's to try it out.
For the ABAP part this is certainly feasible.
The Java part has not only issues with the secure store but also with SID and hostname. The old values are stored in many places in the database and in, depending on the applications installed, many .properties files in the filesystem. So it would be not enough to somehow regenerate the secure store but also change hostname and SID in different places that are not really all documented.
What you are basically looking for is
Note 757692 - Changing the hostname for J2EE Engine 6.40/7.0 installation
with the significant sentence
This note should be applied only when the hostname of a machine
where the j2ee engine was already installed has changed.
It does not replace the SAP official system copy procedure and
MUST NOT be used for copying of an instance to another host and/or with different SID.

Sample dbora file for database having ASM installed

Hi
I have oracle DB10g running on redhat AS 4.
Pliz show me a sample dbora file for a database having ASM installed.
My dbora file doesn't start my dayabase and ASM instance, and i have to start them manually after rebooting the mechine

I have used this manual for installing ASM on my mechine.I have double checked everything.now the problem is certainely my dbora file.
When i configure my dbora file to start database the time mechines reboots.it doesn't work.
and it gives me that error.
But after commenting dbora file and starting database and listener and emctl manually.everything works fine all the instances are available..no problem...
I can't figure out what the problem is ,what 's wrong with my dbora file

Database shut down and file systems are still busy

We have been copying our production DB over to a reporting DB for the last 3 years. The process we use on the reporting database is: shutdown the DB ABORT, restart it, then shutdown immediate. Then we umount the file systems and copy the production over using a Flex Clone on the NETAPP, remount the file systems and start the database back up. We used to shut down the listener which does not share the oracle binaries on the unix system but lately have left the listener up because other DB's use it. Every so often after shutting down the report database in prep for the copy, the file system that contains the binaries is busy and we can't unmount the ORACLE binaries.
So my question is how does the listener know if the database is up or down? Is it reading something on the volumes we're trying to unmount to see if the database is up? We have users that schedule jobs in odd hours and was wondering if them hitting the listener and even though the database is down it's making the file systems busy?
Any help is appreciated.

Listener is NEVER involved with any ongoing packet exchange between client & the DB.
Listener takes original connection request & if the DB is up passes the request to the DB.
After this initial handoff, the listener has NO more involvement with packet exchange between DB & client

How to converrt files on RAW devices in ASM to non ASM file system.

Hi all,
I have on problem .
Is that possible to migrate ASM raw files system to non ASM file .
If possible plzz describe them.
If not also please tell y not?
Thanks in addvance
Regards
Krishna

Hi,
I totally agree with Mahir. And I just want to share one thing:
Use %U to generate guaranteed unique names :
For backupsets, %U means: %u_%p_%c
For an image copy of a datafile, %U means: data-D-%d_id-%I_TS-%N_FNO-%f_%u
For an image copy of an archived redolog, %U means: arch-D_%d-id-%I_S-%e_T-%h_A-%a_%u
For an image copy of a control file, %U means: cf-D_%d-id-%I_%u
Thank you

DNFS with ASM over dNFS with file system - advantages and disadvantages.

Hello Experts,
We are creating a 2-node RAC. There will be 3-4 DBs whose instances will be across these nodes.
For storage we have 2 options - dNFS with ASM and dNFS without ASM.
The advantages of ASM are well known --
1. Easier administration for DBA, as using this 'layer', we know the storage very well.
2. automatic re-balancing and dynamic reconfiguration.
3. Stripping and mirroring (though we are not using this option in our env, external redundancy is provided at storage level).
4. Less (or no) dependency on storage admin for DB file related tasks.
5. Oracle also recommends to use ASM rather than file system storage.
Advantages of DNFS(Direct Network File System) ---
1. Oracle bypasses the OS layer, directly connects to storage.
2. Better performance as user's data need not to be loaded in OS's kernel.
3. It load balances across multiple network interfaces in a similar fashion to how ASM operates in SAN environments.
Now if we combine these 2 options , how will be that configuration in terms of administration/manageability/performance/downtime in future in case of migration.
I have collected some points.
In favor of 'NOT' HAVING ASM--
1. ASM is an extra layer on top of storage so if using dNFS ,this layer should be removed as there are no performance benefits.
2. store the data in file system rather than ASM.
3. Stripping will be provided at storage level (not very much sure about this).
4. External redundancy is being used at storage level so its better to remove ASM.
points for 'HAVING' ASM with dNFS --
1. If we remove ASM then DBA has no or very less control over storage. He can't even see how much is the free space left as physical level.
2. Stripping option is there to gain performance benefits
3. Multiplexing has benefits over mirroring when it comes to recovery.
(e.g, suppose a database is created with only 1 controlfile as external mirroring is in place at storage level , and another database is created with 2 copies (multiplexed within Oracle level), and an rm command was issued to remove that file then definitely there will be a time difference between restoring the file back.)
4. Now familiar and comfortable with ASM.
I have checked MOS also but could not come to any conclusion, Oracle says --
"Please also note that ASM is not required for using Direct NFS and NAS. ASM can be used if customers feel that ASM functionality is a value-add in their environment. " ------How to configure ASM on top of dNFS disks in 11gR2 (Doc ID 1570073.1)
Kindly advise which one I should go with. I would love to go with ASM but If this turned out to be a wrong design in future, I want to make sure it is corrected in the first place itself.
Regards,
Hemant

I agree, having ASM on NFS is going to give little benefit whilst adding complexity. NAS will carrying out mirroring and stripping through hardware where as ASM using software.
I would recommend DNFS only if NFS performance isn't acceptable as DNFS introduce an additional layer with potential bugs! When I first used DNFS in 11gR1, I came across lots of bugs and worked with Oracle Support to have them all resolved. I recommend having read of this metalink note:
Required Diagnostic for Direct NFS Issues and Recommended Patches for 11.1.0.7 Version (Doc ID 840059.1)
Most of the fixes have been rolled into 11gR2 and I'm not sure what the state of play is on 12c.
Hope this helps

Local file system for archive destination in RAC with ASM

hi Gurus .
I need an info.
I have ASM file system in 2 node RAC.
The client does not want to use flash recovery area.
Can we use the archive destination as local file system rather than ASM.
like /xyzlog1 for archvies coming from node 1 and /xyzlog2 for archive logs coming from node 2.
Imortant thing is these two destinations are anot shared with each nodes.
OS is solaris sparc 10.
version is 10.2.0.2

There is huge space in the storage.
Pls tell me in general ho wdo you do this.
Do we take and one disk from the storage and format it with local file system and share it among the 2 nodes?
If so then that mount point will have same mount point name if we see it from other node... ..ryt
In this scenario if one instance is down then from the same shared mount point which is on the same node(down) can apply archves?Here, Earlier you are using any ASM shared location for ARCHIVES ?
if so you can add a CANDIDATE disk to your existing ARHCIVE disk group(shared).
if not from LUN's after format, I.e. candidates based on that you can create a new DISK group(shared) according to your space requirements. THen you can assign to log_archive_dest_1 for both the nodes to single shared location(disk group)

Oc 11gR1 update 3: doesn't show ZFS file systems created on brownfield zone

Subject is a pretty concise description here. I have several brownfield Solaris 10U10 containers running on M5000s, and I have delegated three zpool to each container for use by Oracle. Below is relevant output from zonecfg export for one of these containers. They were all built in the same manner, then placed under management by OC. (Wish I'd been able to build them as green field with Ops Center, but there just wasn't enough time to learn how to configure OpsCenter the way I needed to use it.)
set name=Oracle-DB-Instance
set type=string
set value="Oracle e-Business Suite PREPROD"
end
add dataset
set name=PREPRODredoPOOL
end
add dataset
set name=PREPRODarchPOOL
end
add dataset
set name=PREPRODdataPOOL
end
The problem is, none of the file systems built on these delegated pools in the container appear in the Ops Center File System Utilization charts. Does anyone have a suggestion for how to get OC to monitor the file systems in the zone?
Here's the output from zfs list within the zone described by the zonecfg output above:
[root@acdpreprod ~]# zfs list
NAME USED AVAIL REFER MOUNTPOINT
PREPRODarchPOOL 8.91G 49.7G 31K none
PREPRODarchPOOL/d05 8.91G 49.7G 8.91G /d05
PREPRODdataPOOL 807G 364G 31K none
PREPRODdataPOOL/d02 13.4G 36.6G 13.4G /d02
PREPRODdataPOOL/d03 782G 364G 782G /d03
PREPRODdataPOOL/d06 11.4G 88.6G 11.4G /d06
PREPRODredoPOOL 7.82G 3.93G 31K none
PREPRODredoPOOL/d04 7.82G 3.93G 7.82G /d04
None of the file systems in the delegated datasets appear in Ops Center for this zone. Are there any suggestions for how I correct this?

Do you mean adopt the zone? That requires the zone be halted and it also says something about copying all file systems to the pool created for the zone. Of the 12 zones I have (four on each of three M5000s), seven of them are already in "production" status, and four of those seven now support 7x24 world-wide operations. A do-over is not an option here.

Homogeneous Copy / Converting Distributed System as Central System.

CURRENT SAP LANDSCAPE.
SAP Production System is installed as a Distributed System:
SAP Application Host:_ AIX 5.2 - SAP Application (Central Instance - Central Services) based on NW 7.0 - ERP 2005 SR1.
Database Host: AIX 5.2 - Oracle 10G ver 10.2.0.2.0. - Database remains in SAN (Storage Area Network)
ESCENARIO ONE:
COPYING ONLY CENTRAL INSTANCE AND CENTRAL SERVICES TO A NEW HOST.
Purpose: I want to copy only SAP Application (Central Instance an Central Services) to a new host and connect to my current Database Host .
According System Copy Guide (*) the concept of System Copy includes installation of SAP instances again using copy of source system database, likewise in this Guide I found the following restrictions:
Restrictions.
1.     Copying the database only is not supported!
2.     Copying the central instance only is not supported!
      The migration controller deletes all dialog instances in the database, so the
      system is not complete any longer.
3.     Reinstalling the central instance without the database is not supported!
      The migration controller deletes all dialog instances in the database, so the
      system is not complete anylonger
Questions:
1.     Using Homogeneus Copy (Abap+Java) can I copy ONLY SAP Instances (Central Instance and Central Services) to a new host without copying Database ?
2.     Which is the best procedure to follow for this purpose?
(*) System Copy for SAP Systems Based on SAP NetWeaver 2004s SR1 ABAP+Java
Document version: 1.1 ‒ 08/18/2006
ESCENARIO TWO:
CONVERTING DISTRIBUTED SYSTEM IN CENTRAL SYSTEM
Purpose: Convert our SAP Distributed System (two hosts) in SAP Central System (one host)
Questions:
1.     Using Homogeneous Copy (Abap+Java) can I copy SAP Instances (Central Instance, Central Services) and Oracle Database Instance to only one host (Central System) ?
2.     Is there any specific experience or procedure for this special case?
3. Can I restore Database Full Offline Backup and SAP Application Offline backup in the new server as an alternative ?
Thanks.

Use the distributed system option, as that is what applies to your target system. It is all explained clearly in the system copy guide, which you should definitely reference as appropriate for your software version: http://service.sap.com/instguides -> Installation & Upgrade Guides -> SAP NetWeaver -> SAP NetWeaver 7.4 (or version as appropriate) -> Installation -> 2 - Installation - SAP NetWeaver Systems -> System Copy: Systems Based on SAP NetWeaver 7.1 or Higher -> Windows: ABAP (or system variant as appropriate). In the guide, choose the Database-Specific System Copy: MS SQL Server-Specific Procedure. Also, be sure to check out the chapter on Copying the Database Only - Refresh. Basically, it says to run SWPM on the target database instance, choosing <Product> -> <Database> -> System Copy -> Target System -> <System_Variant> -> Based on AS ABAP (or other as appropriate) -> Database Refresh or Move.

Hi Shane. Not much in the way of thoughts - - but fwiw:
How is the drive attached?
Can you open large files on the drive with other programs?
Are you running any drive compression or acceleration programs (some drives arrive with these installed)?
Can you reformat the drive and try again?
Hi Kirby,
I attached the UltraMax Plus with a USB cable. The UltraMax powers the cable so power is not an issue. I can open other files. Also, there is 500GB of files on the drive so I cannot re-format it. Although, I noted I could import the entire Aperture Library. However, I do not want to create a duplicate on my machine because that would be defeating the purpose of the external drive.

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

Is database using File system, RAW devices or ASM?

Hi there
Is is possible to find out if the database is using File system, RAW devices or ASM for storage?
I think for ASM, we can tell by querying the V$DATAFILE view if it has ' DATA ' or something like that (a name that has ' ' prefixed to it). Is this the only way? How about other sotrage types (RAW and Filesystem)?
Thanks in advance!

Raw depends on your OS - in *nix, likely something like /dev/sdc1
ASM depends on ASM and will include + and will follow an ASM pattern, such as described http://docs.oracle.com/cd/B19306_01/server.102/b14200/clauses004.htm
File depends on OS - in *nix, likely start with a '/' and NOT be in /dev or /proc. In Winders start with C:\ or some other disk path.
Nicely discussed in the docs in the Administrators Guide found at http://tahiti.oracle.com

How to copy out ASM storege for archivelog to normal file system

Hi Expert,
I have two node running Oracle 11gr2 11.2.3 on SUN SOLARIS 64 bit. I need to copy out the archivelog store on ASM Flash recovery area to normal file system. How can i perform this task. How to ensure that after copy this archivelog can use for recovery.
Regard
William

Hi William,
Use this guide:
Step 4. Archived Online logs (archivelogs) and BackupSet stored in FRA
http://levipereira.wordpress.com/2011/09/16/how-migrate-asm-to-non-asm-unixlinux/
As you want copy, you must replace it:
this:
BACKUP AS COPY ARCHIVELOG ALL DELETE INPUT;
to:
BACKUP AS COPY ARCHIVELOG ALL;If you can still using FRA on ASM you can copy without change parameter "db_recovery_file_dest"
e.g
BACKUP AS COPY ARCHIVELOG ALL FORMAT '/u01/app/oracle/%U';
How to ensure that after copy this archivelog can use for recovery.Try it:
VALIDATE ARCHIVELOG ALL;

How to migrate 11gr2 standby database from file system to ASM

Hi,
I have 11gR2 data guard setup of 2 node RAC primary and stand alone standby database.
Primary RAC uses ASM, and stand alone standby DB uses normal file system for data files and archive logs. I want to migrate the stand alone standby DB from file system to ASM.
If you have any ideas or documents on it, kindly please share with me.
Thanks in advance,

Hi Fran,
Thanks a lot for the quick reply. I have another question, I want to have standby in ASM; but ASM home is grid home(CRS+ASM) in 11gr2.
I don't want to configure CRS now for standby, only want to have ASM storage. s it possible to install the grid home only for ASM and not for CRS?
On a stand-alone system, there are still CRS/Grid components that are a part of the ASM install. You cannot NOT install it.

ASM vs ext3 File system(mount point)

Please suggest which one is better for small databases.
ASM or ext3 File system(mount point)?
Any metalink note.

ASM better if you do not want to play with I/O tiuning, (if you tune ext3 file system it woud be the same from performace view),
but it more compilcated for admininstering database files in ASM then in ordinary file system.
Oracle is recomending to use ASM for database file system.
I woud think if you have some development database and nead a lot of cloning, moving of datafiles its better to use ordinary file system,
so you can use copy OS comands, not so complicated.
If you nead some striping, miroring, snapshoting from ext3 you can use LVM on unix/linux.
I am not sure but I think what striping or miroring is better on ASM then on LVM, becouse ASM is doing it better for databse I/O.
