Impdp using ASM or local to instance file

Hi,
I am wondering if anyone compared performance running impdp from
a) ASM with fiber optic (SAN)
b) local file system to instance
Would there be any performance benefit to move from local file system to ASM ?

RAC 10gr2 using ASM for RMAN a cluster file system or a Local directory

The environment is composed of a RAC with 2 nodes using ASM. I have to determine what design is better for Backup and Recovery with RMAN. The backups are going to be saved to disk only. The database is only transactional and small in size
I am not sure how to create a cluster file system or if it is better to use a local directory. What's the benefit of having a recovery catalog that is optional to the database?
I very much appreciate your advice and recommendation, Terry

Arf,
I am new to RAC. I analyzed Alejandro's script. He is main connection is to the first instance; then through sql*plus, he gets connected to the second instance. he exits the second instance and starts with RMAN backup to the database . Therefore the backup to the database is done from the first instance.
I do not see where he setenv again to change to the second instance to run RMAN to backup the second instance. It looks to me that the backup is only done to the first instance, but not to the second instance. I may be wrong, but I do not see the second instance backup.
Kindly, I request your assistance on the steps/connection to backup the second instance. Thank you so much!! Terry

Data Guard: db_file_name_convert/log_file_name_convert when using ASM/OMF

All,
I have a call currently open with Oracle regarding the setting of the parameters db_file_name_convert and log_file_name_convert in a data guard environment. We use ASM / OMF for storage and file naming and my question is basically do these parameters have to be set. The documentation says they do where the file structure is different between PRIMARY and STANDBY.
I have successfully tested failover and switchover without these parameters. I have also added a new tablespace on the PRIMARY and watched it create a new OMF datafile on standby when the logs are switched.
I just can't see a reason for setting them when using ASM / OMF.
I'm hoping someone can enlighten me here because I'm getting nowhere whith support. The following is our Data Guard setup:
PRIMARY
DB_NAME=IBSLIVE
DB_UNIQUE_NAME=IBSLIVE
ASM Disk Groups:
+PRODDATA (Data Files, Control Files, Redo Logs)
+PRODFLASH (Archive Logs, Flashback Logs, RMAN backups)
+PRODLOGS (Multiplexed Control & Redo Logs)
STANDBY
DB_NAME=IBSLIVE
DB_UNIQUE_NAME=IBSDR
ASM Disk Groups:
+DRDATA (Data Files, Control Files, Redo Logs)
+DRFLASH (Archive Logs, Flashback Logs, RMAN backups)
+DRREDO (Multiplexed Control & Redo Logs)
Many Thanks,
Ian.

Ian,
I'm having similar thoughts.
I have created a new instance with files in asm under +datadisk/obosact (this is the smae name as primary)
I then modify the db_unique_name from obosact to obosactdr as is required for standby to work
When I recover (duplicate target database for standby; ) I find that the files are in datadisk/obosactdr not in the datadisk/obosact area
I found this reference http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimaryRACPhysicalStandby.pdf
4. Connect to the ASM instance on one standby host, and create a directory within the DATA disk group that has the same name as the DB_UNIQUE_NAME of the standby database. For example: SQL> ALTER DISKGROUP data ADD DIRECTORY '+DATA/BOSTON';
This step seems to indicate that the location of the files is determined by the db_unique_name not the db_file_name_convert paramenter
DId you ever resolve the issue?

Trouble using asm instance for new database

I have an asm instance and am trying to create a new database that will use the asm storage. I'm using dbca to create the new database. This is a test system on windows so I'm using the asmtool -create flatfiles for disks with the asmallow_only_raw_disks parameter set to false.
If I have #SQLNET.AUTHENTICATION_SERVICES = (NTS) commented out in my sqlnet.ora, then I can't get into asmcmd:
ORA-01031: insufficient privileges (DBD ERROR: OCISessionBegin)
and dbca won't create the new database that uses asm because the dbca gets the same 01031 error when trying to create the control files for that database.
If I have SQLNET.AUTHENTICATION_SERVICES = (NTS) NOT commented out, the I can get into asmcmd, but I can't startup the databases using sys, even though I am sitting at the server,
AND, dbca won't create the new database that uses asm becuase the dbca can't start the instance
credential retrieval failure.
I'm in a catch 22. Something is not right with my system but I just can't seem to figure out what it is.
The asm instance does have a password file.

I let the dbca create scripts and am currently walking through the scripts. I think it's my asm database that is actually creating the problem. I did the orapwd and oradim manually and can startup nomount the instance just fine. The create database statement fails on creating the controlfile but it's saying it already exists. I suspected the dbca form wasn't giving me all the errors like it should.
Thanks for your suggestion on the password file.

Why would anyone want to use ASM Clustered File system?

DB Version: 11gR2
OS : Solaris, AIX, HP-UX
I've read about the new feature ACFS.
http://www.oracle-base.com/articles/11g/ACFS_11gR2.php
But why would anyone want to store database binaries in a separate Filesystem created by Oracle?

Hi Vitamind,
how do these binaries interact with the CPU when they want something to be done?
ACFS should work with Local OS (Solaris) to communicate with the CPU . Isn't this kind of double work?ACFS dont work with .... but provide filesystem to Local S.O
There may be extra work, but that's because there are more resources that a common filesystem.
Oracle ACFS executes on operating system platforms as a native file system technology supporting native operating system file system application programming interfaces (APIs).
ACFS is a general purpose POSIX compliant cluster file system. Being POSIX compliant, all operating system utilities we use with ext3 and other file systems can also be used with Oracle ACFS given it belongs to the same family of related standards.
ACFS Driver Model
An Oracle ACFS file system is installed as a dynamically loadable vendor operating system (OS) file system driver and tool set that is developed for each supported operating system platform. The driver is implemented as a Virtual File System (VFS) and processes all file and directory operations directed to a specific file system.
It makes sense you use the ACFS if you use some of the features below:
• Oracle RAC / RAC ONE NODE
• Oracle ACFS Snapshots
• Oracle ASM Dynamic Volume Manager
• Cluster Filesystem for regular files
ACFS Use Cases
• Shared Oracle DB home
• Other “file system” data
• External tables, data loads, data extracts
• BFILES and other data customer chooses not to store in db
• Log files (consolidates access)
• Test environments
• Copy back a previous snapshot after testing
• Backups
• Snapshot file system for point-intime backups
• General purpose local or cluster file system
• Leverage ASM manageability
Note : Oracle ACFS file systems cannot be used for an Oracle base directory or an Oracle grid infrastructure home that contains the software for Oracle Clusterware, Oracle ASM, Oracle ACFS, and Oracle ADVM components.

Can't create database using ASM (SOLVED)

Hi all
I'm trying to use ASM for the first time, on Oracle 10.2.0.1 on Solaris x64.
I have installed the ASM instance into /opt/oracle/asm/10.2.0 and created disk groups. I have cssd running OK. I am able to start and stop the ASM instance without problems, and I can select from v$asm_diskgroup to confirm that disks are mounted OK.
I have then installed Oracle EE separately into /opt/oracle/server/10.2.0. I first did a software only install, and now I am trying to create a DB.
The problems come when I try to use this ASM instance to host a new database. I first tried to use DBCA to create a new database, but on database creation I got the following errors:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
I then told DBCA just to create the DB creation scripts, and I tried manually running these with SQL*Plus.
When doing it with SQL*PLus, I initially got the same error as shown above. But then something changed (sorry, not sure what), and now the error I get is:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
I've put some debug info below, showing me succesfully connecting to the ASM instance and then attempting to create the DB using the db creation scripts, showing the error at the end. You can see that the oracle OS user is able to connect fine to ASM, then I swithc ORACLE_SID and ORACLE_HOME to the EE install and try to create the DB, at which point it apparently can't connect to ASM any more.
I've tried the DB creation many times, and in between attempts I completely empty $ORACLE_HOME/admin/<dbname> and delete the files related to the attempted install from $ORACLE_HOME/dbs/ . I've also stopping/starting ASM, rebooting, and I've done the install of ASM and EE a couple of times over in case I made any mistakes in my earlier attempts.
Any help would be much appreciated!

Update: I've worked out the difference between the two sets of errors I get.
The basic error is this:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
However if my init.ora contains the line:
control_files=/opt/oracle/server/10.2.0/dbs/cntrlNEONREL1.dbf
then I instead get the second error:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
So basically these must be the same error, just in the second case I'm not trying to put the control file on the ASM so it fails at a different point.
But both errors must be because of the same cause, I suppose.

Thanks in advance

Thanks both
Really the problem initially was because of this:
[INS-06006] Passwordless SSH connectivity not set up between the following node(s): [node1, node2]. CVU may reports "PRVF-4007 : User equivalence check failed for user "user"" for same error
and I had to install node1 first and after node2 manually and perhaps for this the product was not well linked.
I resolved the problem establishing the keys with the wizard and after copying the following files from node1 to node2
/home/grid/.ssh -------> /home/grid/.ssh
authorized_keys
known_hosts
This is the procedure if you run the wizard at the node1.
The problem is that the wizard creates the keys incompletely...
Thanks

Using ASM in a cluster, and new snapshot feature

Hi,
I'm currently studying ASM and trying to find some answers.
From what I understand and experienced so far, ASM can only be used as a local storage solution. In other words it cannot be used by network access. Is this correct?
How is the RDBMS database connecting to the ASM instance? Which process or what type of connection is it using? It's apparently not using listener, although the instance name is part of the database file path. How does this work please?
How does ASM work in a cluster environment? How does each node in a cluster connect to it?
As of 11g release 2, ASM provides a snapshot feature. I assume this can be used for the purpose of backup, but then each database should use it's own diskgroup, and I will still need to use alter database begin backup, correct?
Thanks!

Is this correct?Well, you are missing one point that it would entirely depend on the architecture that you are going to use. If you are going to use ASM for a single node, it would be available right there. If installed for a RAC system, ASM instance would be running on each node of the cluster and would be managing the storage which would be lying on the shared storage. The process ASMB would be responsible to exchange messages, take response and push the information back to the RDBMS instance.
How is the RDBMS database connecting to the ASM instance? Which process or what type of connection is it using? It's apparently not using listener, although the instance name is part of the database file path. How does this work please?Listener is not need Markus as its required to create the server processes which is NOT the job of the ASM instance. ASM instance would be connecting the client database with itself immediately when the first request would come from that database to do any operation over the disk group. As I mentioned above, ASMB would be working afterwards to carry forward the request/response tasks.
How does ASM work in a cluster environment? How does each node in a cluster connect to it? Each node would be having its own ASM instance running locally to it. In the case of RAC, ASM sid would be +ASMn where n would be 1, 2,... , going forward to the number of nodes being a part of teh cluster.
As of 11g release 2, ASM provides a snapshot feature. I assume this can be used for the purpose of backup, but then each database should use it's own diskgroup, and I will still need to use alter database begin backup, correct?You are probably talking about the ACFS Snapshot feature of 11.2 ASM. This is not to take the backup of the disk group but its like a o/s level backup of the mount point which is created over the ASM's ACFS mount point. Oracle has given this feature so that you can take the backup of your oracle home running on the ACFS mount point and in the case of any o/s level failure like someone has deleted certain folder from that mountpoint, you can get it back through the ACFS snapshot taken. For the disk group, the only backup available is metadata backup(and restore) but that also does NOT get the data of the database back for you. For the database level backup, you would stillneed to use RMAN only.

Advice on whether to use ASM for 11gR2 databases

Hi all,
Hope I can get some advice here for ASM.
I'm going to upgrade all my 10.2 EE databases to 11gR2, and I will not be running RAC, only single instances and Data Guard. My storage is HP SAN. I wonder if it is worth the trouble (in our small shop) to run ASM.
Currently, my backups are done from a SAN perspective only, meaning that whatever is in the SAN storage is backed up.
How do I back up the files in ASM? Do I have to copy the backupsets to file system first ?
Thanks!

For small databases performance gain is zero, you only add complexity where a normal file system would be sufficient.Disagree.
Also, the reasoning is not valid. ASM works at device level. Not at cooked file system level.
This means that ASM directly uses the LUN (seen as a local scsi device) of the SAN. See LUN. Use LUN. That simple.
Not using ASM means that the o/s needs to be updated and configured. That LUN needs to be mounted. It needs to be formatted. The mount needs to be made permanent (via fstab or whatever).
This makes ASM less complex and cooked file system more complex.
Also consider that the mount and its contents are exposed to other s/w and processes and users. This raises issue such as access control and security - and the possibility of errant s/w trashing a database file because it happens to be running on the wrong mount or wrong directory.
This is not the case with an ASM diskgroup as it is not mounted and not visible as a normal cooked file system.
And if a cooked file system feature needed for a non-database files, an ACFS volume can be created in the diskgroup and mounted as a clustered file system. So it is not as if you loose the option of having a cooked file system on a LUN, when using ASM.
Database size has nothing to do with the decision between cooked file system or ASM when using SAN LUNs. Ease of use, manageability, and feature set, have. From this perspective a cooked file system for database storage is old and clunky and insecure, and ASM is flexible, performant, scalable and secure.

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye

What are the caveats of using ASM as storage for RMAN backupsets?

Hello all,
We are currently evaluating RAC as our standard database platform. Until now we have been using 10g single instance with ASM for datafiles and local filesystems for RMAN backupsets and archivelogs. We chose to use local fileystems for backup components so that we can utilize a Tivoli filesystem backup in order to secure the backup pieces to tape.
With RAC, we are looking into a shared location for backupsets and archivelogs. OCFS2 is out of the picture due to it not functioning on top of linux LVM. It appears that our only "shared" option is to use ASM for backupsets and archivelogs.
My concern is that while the data diskgroups and rman diskgroups will be separate, they are both running on ASM and therefore if ASM fails or is corrupted, we have nothing. My current plan is to utilize the Tivoli RMAN MML (TDPO) to backup the backupsets to tape after the ASM backupset has completed.
What experiences have been had with using ASM for RMAN backups?
Any advice on additional protection we can employ to ensure that the database remains recoverable?
Thanks in advance,
David

I've personally haven't implemented RMAN with ASM, but you may want to review Faster Backup, Faster Recovery which discusses RMAN utilizing ASM.
And although you may not get any of the negative aspects from these presentations, you may want to check out High Availability Customer Case Studies, Presentations, Profiles, Analyst Reports, and Press Releases.
Hope this helps!

Local Portal instance in branch office

Are there any solutions for speeding up Portal for remote/branch office users?
We have a lot of users who will be accessing the corporate network & Portal over relatively slow lines or satellite links; buying more bandwidth is physically not an option in some places we operate.
Has anyone looked at installing a local Portal instances in the field, and replicating PCD content to still allow central administration?
Does SAP have any offerings in this space? Global/Federated Portal does not address the speed issue - users still go across the WAN to render their content. Portal Lite is still too slow.
Any and all ideas appreciated.
RBL

Well spoken - you can't speed up the speed of light.
Luckily, many of our content sources CAN be replicated to the branch offices. We use Lotus Notes/Domino for many web apps & web content; DFS (Microsoft replicated file system) for distributing files; and Exchange Public Folders for replicating commonly accessed email-type postings.
Have you (or anyone out there) found any solutions for keeping PCD updates in sync between a head office Portal and a branch office Portal?

Can Grid Control 10gR2 create a standby database when primary db uses ASM?

Does anyone know if Grid Control 10gR2 will be able to create a standby database when the primary database uses ASM for data files, redo log files, and archive log files but the standby database will use mounted disks? If it can, would it matter that the primary db will be a RAC cluster and the standby will be a single instance db?

I appreciate your reply and hope you are correct. Have you had a look at the 10gR2 Grid Control to confirm this or are you only going on published statements? The reason I ask is because previous versions of Grid Control claimed to support ASM but they would only allow you to work with them AFTER you had created a standby database manually but you couldn't actually use Grid Control to create a standby database from a primary database that had its log files on ASM disks.

Impdp using ASM or local to instance file
