ORACLE ASM OR ZFS IN SOLARIS 11

ORACLE DBA EXPERTS
What kind of storage technology is recommended in order to implement an Oracle 11gr2 database in a Solaris 11 OS?
-Oracle ASM or the Solaris 11 ZFS filesystem.
Its any difference between the performance of both storage technologies?
Thanks for answer my questions and i wish to yours a very "Happy Hollydays".
Sincerely,
JOHN JAIRO GOMEZ LAVERDE

From what I understand Oracle recommends ASM. You cannot directly compare ASM with ZFS. ASM is a storage solution providing data management, availability and redundancy specific to Oracle. ZFS is an advanced file system. Whether you choose one over the other will depend on your storage requirements and knowledge.

Oracle ASM Configuration on Solaris Cluster - Oracle 11.2.0.3

Hi,
I want some clarifications!
I need to set Active and Passive Cluster settup on Solaris 10 SPARC Operating System, the HA software is Solaris Cluster and Oracle 11.2.0.3.
1) I understand "Single instance Oracle ASM is not supported with Oracle 11g release 2" so we need to go for Clustered ASM - is it required to use RAC framework in this case?
2) When i use the RAC framework, do i need to have license for RAC?
Am new to Oracle, any help is appreciated.

Oracle ASM on top of ZFS volumes

What kind of overhead is involved if we configure Oracle ASM on top of ZFS volumes? Has anyone performed benchmarks using this scheme?

I've not done it personally with DNFS but I have created a multitude of clusters with NetApp on their NFS file system without ever having an issue other than saving a lot of money.

Oracle ASM

Hi,
I have a new server Sunfire X4100 4x146G SAS disks running Solaris 10 X86 U4.
1 pair of disks is Hardware mirrored for the OS. I created Oracle home on this partition and installed oracle 10g.
I have been trying to decide if using Oracle ASM for the othere two disks is a good idea or not. Should I us ASM to create a disk group with the two remaining disks and run my production database on it or should I stick with manual storage management and raid those disks in hardware or even ZFS... ahh the choices?
The white papers talk about databases with loads of disks and controllers, I am not at that level of hardware and expenditure, YET!
Do ASM and OMF remove the need for me to manage the datafiles for the tablespaces?
Do they handle the layout and optimization of the tables within a tablespace or is that still down to the admin to define the size of the extents during expansion etc?
Can I run a standby database using non ASM storage from a database which uses ASM storage? If this is possible how are the datafiles handled on the standby database?
I guess I could keep reading but I hoped some benevolent sole might already know the answers and save me days of reading!
Finally, How reliable is ASM anybody care to comment? I know I can recover data using my existing OS level database files and ASM makes me uneasy...

You really want to invest in http://www.oracle.com/technology/bookstore/index.html
Bottom line: with ASM, the database still runs against RAW disk (physical or LVM) for best possible performance. However, instead of grabbing an entire disk for each tablespace, ASM holds the metadata that tells the database instance where to read and write for specific tablespaces. This allows ASM to coordinate things like striping in a way that is really beneficial for the database.
The white papers talk about databases with loads of
disks and controllers, I am not at that level of
hardware and expenditure, YET!ASM allows you to grow to that when needed.
>
Do ASM and OMF remove the need for me to manage the
datafiles for the tablespaces?Effectively yes. ... remove? how about minimize ...
Do they handle the layout and optimization of the
tables within a tablespace or is that still down to
the admin to define the size of the extents during
expansion etc?ASM uses the principals of SAME (Stripe and Mirror Everything) to minimize admin.
>
Can I run a standby database using non ASM storage
from a database which uses ASM storage? If this is
possible how are the datafiles handled on the standby
database?Logical or physical standby. (I only have experience in the physical standby matching the storage technique of the prime. But I don't see why it should impact the physical standby to mix.)
>
I guess I could keep reading but I hoped some
benevolent sole might already know the answers and
save me days of reading!I know what you mean. The book mentioned above does consolidate a lot of the reading - worth the price and effort.
>
Finally, How reliable is ASM anybody care to comment?Very - you are still using RAW disk and Oracle has been doing that for decades.
I know I can recover data using my existing OS level
database files and ASM makes me uneasy...Not unusual.

Help needed on installation of Oracle 9i EE on Sun Solaris 8

Hey,
Help needed on installation of Oracle 9i EE on Sun Solaris 8. The problem I met was: we followed the installation guide from the documentation. And we selected the choice "install software only". After it was done successfully, we run Database Configuration Assistant utility to create a database instance. But finally it always tried to create the instance at the root directory ( / ) which doesn't have enough space and then failed. The case was that we have set the enviroment parameters: $ORACLE_BASE = /export/mydata, $ORACLE_HOME = /export/apps/oracle9i. That means it should be installed at /export/mydata, but it didn't. Any help or advice are welcome. Thanks.
Simon

I have downloaded Oracle 11G R2 version from Windows and extracted it in Windows and copied it into DVD after extraction in two folders. Now I am mounting that DVD in Solaris 10 installed in my VMware . I made a new directory named as 'installation ' under /export/home/oracle and copied the folders from DVD to 'installation' folder. Now I am entering installation folder and try to do ./runInstaller as 'oracle ' user and getting the error mentioned before.

Installation problem of Oracle 8.1.7 on solaris 10 x86

Hi,
I tried to install the Oracle 8.1.7 on solaris 10 x86 and I got an error message shows: "cannot write to /opt/oracle/product/8.1.7/jar/classes2.jar".checking the log it shows:
Exception: IOException2
and exception: copyGroupFromJar. I ignored the error but the installation failed.By the way, I was not asked to run root.sh during the installation. Can anyone kindly tell me how to make it?
yours
zeushd

Here are some additional statements for 10g on Solaris 10g x86:
1. Execute runInstaller with the -ignoreSysPrereqs option.
2. Select 'Do not create a starter database' when installing Oracle 10g.
3. During installation, the warning message 'SUNWsprox package not installed' can be ignored. Press Continue to resume the installation.
4. Download and install patch 4186426 from metalink.oracle.com after installing Oracle 10g software.
5. If you have an End User Solaris 10 distribution, install the SUNWuiu8 package prior to installing the 10g client.

Petstore 1.3 with Oracle 8.1.7 on Solaris 9 - deployment error

Hello,
I'm trying to get Petstore 1.3 shipped with WebLogic Server 7.0 to work with Oracle
8.1.7 on Solaris 9 with a third-party (Oracle) jdbc driver (classes12). I did
the following:
1) created a new connection pool with the correct Oracle database URL and driver
class name (oracle.jdbc.driver.OracleDriver), also user/password properties for
the Oracle db, and the WL server selected in targets;
2) created a database schema for Oracle based on the data in Pointbase and the
weblogic-cmp-rdbms-jar file as well as petstore_catalog_utf8.sql;
3) created a new tx datasource pointing to the Oracle conn pool;
4) modified the catalog component's ejb-jar.xml file's env-entry to contain CatalogOracleDAOImpl;
5) put weblogic.jar in the classpath;
6) used Java's dbping utility to check connection to the database via the Oracle
driver (works fine--no network adapter error or anything related).
I then rebuilt the ear files (build is successful), but when deploying get the
following error:
"Cannot deploy EJB AccountEJB from customerEjb.jar. Cannot find datasource for
JNDI datasource-petstorePool" and says to make sure the JNDI name and deployment
descriptors are correct (I checked the customer component's deployment descriptors
against the tx datasources' JNDI and they match).
What step(s) am I missing? Any suggestions on what else I need to modify would
be very much appreciated.
Thanks,
Beverly Claire

Beverly:
If you have 8.1, then you should be able to simply and easily create a
connection pool to petstore via the console.
The current error you encountering: "petstorePool does not exist" is
because either:
petstorePool is not defined or there was a failure when the pool was first
created trying to connect to the DBMS.
The full errror should be in the log file prior to the TXDatasource error.
Cheers

Hello Rob,
Thanks for your reply. Yes, the tx datasource's JNDI name isdatasource-petstorePool.
The server log says that "petstorePool does not exist".
My conn pool contents:
Name: petstorePool
URL: jdbc:oracle:thin:@<replaced with db address>:<replaced with dbport>:<replaced
with db SID>
Driver Class Name: oracle.jdbc.driver.OracleDriver
Properties: user=<replaced with username*>

*same username and password used to set up the Petstore tables in Oracledb.

No, actually we're not evaluating in the sense of just-trying-things-out.One
of our clients is considering an application server. They're relying on usfor
help in choosing which would be best. As of now, we are comparing BEA WLServer
7 and 8.1, Sun ONE Application Server 7 EE, Oracle 9i Application Server,and
Fujitsu Interstage v5 Application Server. For cluster testing andperformance
comparison purposes, we'd like to use the same J2EE Application across allservers,
and the obvious choice is Petstore 1.3. One aim is to smoothly connect toan Oracle
database. The other app servers provide setup scripts and databaseschemas for
Petstore-with-Oracle, so db conn and deployment are not a problem at all.As for
WL, we've been trying to get Petstore (both the version downloaded fromSun's
Java Blueprints and the version that shipped with WL 7) to work withOracle, but
no luck so far. It's getting a bit frustrating, given the ease with whichthings
worked out with the other app servers.
Yes, I've tried out Avitek MedRec for WL 8.1, and this time BEA has kindlymade
provisions for Oracle db, so connection to Oracle is not a problem. I'mhoping
BEA will come around to doing the same thing for Petstore, although I'mguessing
that won't be in the near future.
Any other suggestions would be much appreciated.
Thanks,
Bevery Claire

Isqlplus with oracle 8.1.7 on Solaris 9x86

I installed oracle 8.1.7 on Solaris 9x86, all is fine.
But I dont see any where that I could use isqlplus through nestcape.
Is there any way that I could start isqlplus through my browser.
Please help!!!

You mean that I can install isqlplus from oracle9i into my oracle8.1.7.You would need to install into a new Oracle9i-only directory (i.e. a
new ORACLE_HOME). The iSQL*Plus in it would be able to connect to
your existing 8.1.7 database using Oracle Net.
Unfortunately I see 9i is not supported on Solaris x86 (though 10g is
"projected".)
The French iSQL*Plus 8.1.7 document you refer to talks about the first
pre-production version of iSQL*Plus released. It cannot be
recommended for use, and is no longer available.

Can I install Oracle 8.1.7 on solaris 2.8

We have a working product which uses oci 7.x calls on solaris 2.7 OS and the oracle version is 8.1.7.
But when we installed oracle 8.1.7 on solaris 2.8 OS , We are unable to connect to Oracle data base using the same executables.
My question is : --- Is oracle 8.1.7 is supported on solaris 2.8 OS ?
thanks and regards

Yes! We made it only in 1 month, but now it works fine.

Oracle 8.1.7 on Solaris 8

hi everyone,
I am totally new to Oracle ... just finished installation
of Oracle 8.1.7 on Solaris 8 .. the automatic database
creation step failed for some reason.
Now when I try to use dbassist to create a new database,
I get an ORA 03114 error "not connected to ORACLE".
It does create the database creation shell scripts, so I
tried manually executing those scripts and the following
sequences of events ensued.
SVRMGR> connect internal
Connected.
SVRMGR> startup nomount pfile = "/opt/oracle/admin/B/pfile/initB.ora"
ORA-03113: end-of-file on communication channel
SVRMGR>
Any idea on what could be going on ... any help is appreciated ... the quicker
the better as this is holding a lot of work back on our research.
thanks
