Oracle 11g RDBMS/ASM on StorageTek 2500 Series SAN

Hi All:
We are running in a data warehouse environment using extensive 11g RDBMS partiioning and parallel query servers on fairly good sized tables. All of the storage is ASM based with external RAID 0+1 redundancy configured on SUN StorageTEK SAN ( fibre channel HBA's unswitched) The physical rAID device consists of only 8 10K RPM spindles
Oracle enterprise Manager's ASM performance page is telling me that the cumulative stats for I/O response time are 75.79 ms and that average throughput is about 1/MB per second. This seems pretty slow and consistently my query performance reports are showing extensive I/O waits.
What are other people seeing for aberage response time /I/O throughput for read intensive well tuned systems?
(because we are using parallel query the PX coordinators are using the large pool rather than the buffer cache so the majority of the I/O is direct reads rather than scattered I/O)
My question is would increasing the number of spindles in the existing ASM disk group significantly reduce I/O response time and increase throughput.
With an expansion tray I could go up to 16 spiondles -- could I comfortable assert to my management that such an outlay would halve the ASM I/O response time and double the I/O throughput -- i highly doubt it will scale that literally but would like to know if increasing spindle count would definitely reduc e the I/O latency we are witnessing....
Avg resp Time (ms) Throughout (MB/second)

Installing oracle 11g with ASM

Hi ,
Thanx for priviuos supportss.
Here we are going to configure a new set up on new hardware :
clients requirements :
oracle 11g with ASM :
Number of instance = Single database
Platform = IBM AIX 6.1
Kindly provide me any guidence / steps regarding same as i havent configured this yet..

Thank u very much for interest ...

Can u plz ans my below questions :
1.When we say ASM , is it considedred as a Grid Infrastructure ASM is one component of Grid Infrastructure. You can't have ASM without it.
2.What is ORACLE RESTART , do i really need to install it...It is also part and parcel of Grid Infrastructure - at least for a stand-alone.
there is an entire forum dedicated to GI installation, located [url https://forums.oracle.com/forums/forum.jspa?forumID=62]here

And fwiw, if you run the GI installer, one of the options is gives is to Install Grid Infrastructure for a standalone server. Pretty painless as long as you have correctly configured your disks that will be used with ASM.

ASM Installation on Oracle 11g Clusterware (RAC) environment

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes
http://oraclepitstop.wordpress.com/2008/02/15/raw-devices-on-rhel-5-or-oel-5/
ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)
on production, I use ASMlib... + ASM + 10g

StorageTek 2500 - Mirroring Best Practices

I am setting up a new StorageTek 2500 array.
One of my volumes will be assigned 12 hard drives from a single shelf and will use Raid 1+0.
The CAM asks me to manually assign pairs of drives for mirroring.
I would like to understand if there are any single point of failures within the disk shelves that I should be aware of when deciding this.
Do the StorageTek 2500 series disk shelves have multiple backplanes?
- If so, which hard drives are assigned to each backplane? I want to avoid assigning both disks that are being mirrored to the same controller. I don't want to lose the data on both drives in the event of a hardware failure.
- If not, is it recommended to pair one drive from one shelf, with a drive from another shelf to eliminate single point of failure?
Does anyone have any suggested best practices when assigning pairs of drives for mirroring on the StorageTek 2500?
Thanks

I do not understand what you mean by shelf. The drives are connected to the same backplane, regardless of what pair you create. The SPOF is the backplane, nevertheless it is unlikely to fail.

Creating Oracle 11g Database Manually on ASM on 11g R2 Grid

Hi:
Earlier added this issue alongwith Grid installation. Only Jorg replied to me but could not find a complete solution. So thought of starting a new thread.
Wanted to know if any one of you have successfully created Oracle Database Manually on ASM on Oracle 11g R2 Grid.
I have installed Oracle 11g R2 grid (grid user) and Oracle 11g R2 DB software succesfully (oracle user).
Now trying to create a database manually on ASM as Oracle user.
First I create an pfile in $ORACLE_HOME/dbs
then I started by db on nomount stage. when I create a spfile on to my ASM diskgroup I get
I have created 2 diskgroups '+DGASMSPFILE' (ASM Spfile) and '+DGDBDATA' (for database)
Grid is up and running.
From Oracle user:
Have created a sample initDBRAC.ora
Now I want to create Oracle Database Global Spfile into '+DGASMSPFILE'
export ORACLE_SID=DBRAC
$ sqlplus / as sysdba
SQL> create spfile='+DGASMSPFILE/spfileDBRAC.ora' from pfile;
ORA-17502:ksfdcre:4 failed to create file +DGASMSPFILE/spfileDBRAC.ora
ORA-12547: TNS lost contact
"Oracle user" should have privileges to access ASM diskgroup right? What is the permission set for /dev/sdc* (earlier it was root:oinstall I changed it to grid:oinstall even then no difference.
Trace output:
ASM_DISKSTRING= /dev/sdc*

Hi Sebastian:
When I installed grid software, oracle db software and created oracle db manually things worked fine.
When I restart the RAC environment I found the following issues:
1) all the resources does not come up automatically, once i issue crs_start -all all the services comes up. (most of the resources related to node1 comes up but cluster resources related to node2 does not come up) crsctl check crs shows that things are online.
2) wanted to recreate a database manually after restarting the RAC enviroment. To start of as usual tried to create a spfile in ASM disk "Create spfile='+DGDBSPFILE' from pfile'
I get ORA-17502:ksfdcre:4 failed to create file +DGDBSPFILE'
12547: TNS: lost contact
looks like permission problem.
The same command worked before restarting the RAC environment. Pls let me know if I am missing out anything.
Is it because i am unable to access ASM instance.
3) As you had mentioned tried to set the sbit by executing the following statement:
$ /opt/grid/bin/setasmgidwrap o=/opt/oracle/product/11.2.0/db/bin/oracle
should this be put into "rc" folder in linux so that it gets set everytime linux starts up. because once i restart the permission get changed.
I should execute it from grid user to change the permission of 'oracle' binary in 'oracle user' right?
Can you explain me why is this required (sbit).
Thanks.

Dinesh

How to Create Manual Standby for a Oracle 11g RAC with ASM to Single Instan

Hi All,
I have a task to configure a Single Instance Standby Database with ASM for 2-node Primary RAC+ASM database.
Version using : 11.1.0.6 Oracle 11g --- *" STANDARD EDITION "* Please note datagaurd will not be supported in standard edition.
Primary database - 2 -Node RAC using ASM storage (All datafiles, redologs, controfile and archive logs)
Need to setup a single instance standby database manually and than using scripts to transfer the archive logs from primary server to standby server to do recovery time to time.
Please let me know if there are any configuration document(s) which can help me to set the manual standby? or need your kind help to give your valuable ideas how to go in above situation.
Thanks in advance

Well if the archive logs are stored in ASM on the primary nodes, you almost definitely want to be using RMAN to access them. Then to transfer between primary and standby there are many options, this is essentially the step that Data Guard takes care of - so if you (and I) are running Standard Edition, this is the part to "worry" about.
I'm not really sure what you mean by this:
As in standard edition the archive destination will be on ASMI don't think the Edition of Oracle (Standard or Enterprise) dictates where and how you store your archive logs, but it's possible I've misunderstood what you mean...SE dictates that database storage for RAC will be ASM, including archive log files. Anything else is not officially supported. I haven't tested but it may be that you can use LOG_ARCHIVE_DUPLEX_DEST to specify a local filesystem for archive log files as well.
If that doesn't work you'll have to script rman "backup as copy" jobs regularly and then transport the results of that.

By the way, it seems Robert has been pretty helpful, it's polite to give him some points dude. And since this is your thread, not mine, give him a "helpful" from me too :p
El DBA
Incidentally if you are forced down the RMAN backup as copy route then this will likely throw your current backup retention strategy somewhat, you'll need to think carefully about when an archivelog can be deleted following backup, how many times it might be backed up and so on. I do understand, and have argued for, the use of SE RAC. I also understand and have argued for and implemented manually managed standby a number of times. However by the time your primary database is a RAC instance and you need a standby for DR etc then you really have to look very seriously at whether Standard Edition is still the right investment or not. You will be spending a lot of DBA time managing and troubleshooting this, and you will find that it is less reliable than the off the shelf solution. I suspect that you are very close to the point where an EE installation becomes a worthwhile investment here.

Regarding ASM in Oracle 11g

Hi
I would like to use ASM storage for my single instance oracle 11gR2 database. I am a little bit confused so that asking some question about Oracle 11g ASM.
1. Does Grid Infrastructure mandatory for installation Oracle 11g ASM instance?
2. Without installation Grid Infrastructure can I full fill my requirements ?
Regards
Rabi

"If you plan to use Oracle Restart or Oracle Automatic Storage Management (Oracle ASM), then you must install Oracle Grid Infrastructure before you install and create the database. " -- http://docs.oracle.com/cd/E11882_01/install.112/e47689/oraclerestart.htm#LADBI999

Oracle 11g ASM - looking for some answers

Hello,
I reviewed a bunch of stuff about Oracle 11g ASM from various sources, but still haven't figured out some answers. Perhaps someone could help me to find the missing links please.
Q1) ASMLib seems to require partitions. ASM recognizes partitions as well as disk devices. So why not using partitions in general? At least I could use ASMLib later without having to reconfigure the drives and loosing all data. Correct?
Q2) The ASMLib driver is not installed by default, and unlike other ASM components is not available from the public yum repository for OEL 5.5. After some searching I found it available for download, but why is it not more obvious. Should it not be used anymore? http://www.oracle.com/technetwork/topics/linux/downloads/rhel5-084877.html
Q3) ASM will not see drives or partitions unless the device ownership is set to Oracle. When Enterprise Linux starts, it resets all block devices to the owner of root. The solution is to create a udev rules file: e.g.:
/etc/udev/rules.d/99-oracle.rules:
KERNEL=="sda", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sdb", OWNER="oracle", GROUP="dba", MODE="0660"
Before using ASMLlib, I need to configure the driver, which will ask me for the default user and group who owns the partitions (/etc/init.d/oracleasm configure)
I conclude that using ASMLib will therefore not require a udev rules file, correct?
Q4) The Oracle documentation outlines that ASMLIB is an application programming interface (API) developed by Oracle to simplify the operating system–to-database interface and to exploit the capabilities of vendors' storage arrays on Linux-based systems. What does this mean, examples? Isn't this what ASM does in general, why ASMLIB?
Q5) I installed ASM and would like to re-configure it. Apparently ASM alone does not provide an interface other than sqlplus. In order use ASM with Enterprise Manager, I need to install a database or EM 11g (?) Grid control. Correct?
Thanks,
Markus

Hi,
So you got answers for 3 4 and 5
Q1) ASMLib seems to require partitions. ASM recognizes partitions as well as disk devices. So why not using partitions in general? At least I could use ASMLib later >without having to reconfigure the drives and loosing all data. Correct?Using ASMLib, you can use your understandable disk partitions names rather than creating raw devices and adding entry in /etc/raw file and changing rights on every startup, so it makes life easier. Read post of "wcoekaer" from following thread
ASMLib and Linux block devices
Q2) The ASMLib driver is not installed by default, and unlike other ASM components is not available from the public yum repository for OEL 5.5. After some >searching I found it available for download, but why is it not more obvious. Should it not be used anymore? http://www.oracle.com/technetwork/topics/linux/downloads/rhel5-084877.html
I am not sure about OEL 5, but i have seen it in OEL 4 and i can install this package during OEL 4 installation. But i believe you should be able to find this package in one of the Disks of OEL 5

Upgrade ASM Oracle 10.2.0.4.0 to ASM Oracle 11G R2 on Windows 2008 SP2

Please advice on procedure or where I can find information on upgrading ASM from Oracle 10G to Oracle 11G R2 (Winwdows 2008 SP2 64bit environment) for mutiple Oracle instances (not a RAC environrment).
The current scenario is as follow:
- Two oracle homes; one for ASM instance and another for the Oracle Databases (in current case only two oracle instances possiblly more at a later time). Both (ASM and Oracle databases) have the same version of Oracle 10.2.4.0.
The Oracle database home can't be upgraded due to application restricition (Vendor Application not tested on Oracle 11G) but will like to upgrade the ASM instance to Oracle 11G (Oraclle 11G R2).
Questions:
- Is is a feasable solution? Can I upgrade ASM instance to Oracle 11G R2 to take advantage of new features? Will the ASM upgrade scenario is compatible with the Oracle Database Instance running Oracle 10G? Any possible issues that I should be aware or concerns?
Is it possible to have ASM running in Oracle 11G R2 and service the need of Oracle database instance running in 10G?
Please advice or where I can obtained information on the matter. Also possibly if someone has done it on Windows 2008 SP2 (not Windows 2008R2).
Thanks in advance

Thanks so I can upgrade the ASM Home instance and leave the Oracle Databases home on Oracle 10.2.0.4.
I agree with you not just 100%, actually 120%. Fortunately, the vendor is finally understanding by pressure provided by DBAs and Application Teams that they are very behind the curve. It is working and by summer we should have an oracle 11G compatible product.
The same thought went when I was told of their compatability database level.

Time Series in Oracle 11g

Oracle 8i hase Time series for defining calendars and other functions. How does Oracle 10g/11g support Time series features. I could not find any information about Time Series in the 10g/11g documentation.

Thanks a lot for the responses.
I looked at the 11g Pivot operator and is altogether a new feature compared to the Time series of 8i.
I would like to explain with an example.
1) The following query creates a table named stockdemo_calendars and defines a calendar
named BusinessDays. The BusinessDays calendar includes Mondays through Fridays,
but excludes 28-Nov-1996 and 25-Dec-1996. Explanatory notes follow the example.
CREATE TABLE stockdemo_calendars of ORDSYS.ORDTCalendar (
name CONSTRAINT calkey PRIMARY KEY);
INSERT INTO stockdemo_calendars VALUES(
ORDSYS.ORDTCalendar(
0
’BusinessDays’,
4,
ORDSYS.ORDTPattern(
ORDSYS.ORDTPatternBits(0,1,1,1,1,1,0),
TO_DATE(’01-JAN-1995’,’DD-MON-YYYY’)),
TO_DATE(’01-JAN-1990’,’DD-MON-YYYY’),
TO_DATE(’01-JAN-2001’,’DD-MON-YYYY’),
ORDSYS.ORDTExceptions(TO_DATE(’28-NOV-1996’,’DD-MON-YYYY’),
TO_DATE(’25-DEC-1996’,’DD-MON-YYYY’)),
ORDSYS.ORDTExceptions()
-------------- How can I create such calendars in 11g?
2) For example, the following statement returns the last closing prices for stock
SAMCO for the months of October, November, and December of 1996:
select * from the
(select cast(ORDSYS.TimeSeries.ExtractTable(
ORDSYS.TimeSeries.ScaleupLast(
ts.close,
sc.calendar,
to_date(’01-OCT-1996’,’DD-MON-YYYY’),
to_date(’01-JAN-1997’,’DD-MON-YYYY’)
) as ORDSYS.ORDTNumTab)
from tsdev.stockdemo_ts ts, tsdev.scale sc
where ts.ticker=’SAMCO’ and
sc.name =’MONTHLY’);
This example might produce the following output:
TSTAMP VALUE
01-OCT-96 42.375
01-NOV-96 38.25
01-DEC-96 39.75
3 rows selected.
--------------------- How can I get the above ouput without Time series functions and calendars in Oracle 11g?

Which is better to install Oracle 11g database based on ASM or Filesystem

We will install 2 sets of Oracle 11.2.0.3 on Redhat Linix 5.6 and configure Data Guard for them further -- one will be a primary DB server, the other will be a physical standby DB server. The Oracle DB stoage is based on SAN Array Disk with 6TB size. Now there are two options to manage the DB datafiles:
1. Install Oracle ASM
2. Create the tranditional OS filesystem
Which is better? in the past, our 10g data guard environment is not based on Oracle ASM.
Someone think if we adopt the oracle ASM, the shortcomings are :
1. as there is one more instance that will consume more memory and resource.
2. as the ASM file system cannot be shown out on the OS level directly such as "df" command, the disk utilization monitor job will be more difficult. at least it cannot be supervised at OS level.
3. as the DB bshoule be done the daily incremental backup (Mon-Sat) to Local Backup Drive. the bakup job must be done by RMAN rather than user-managed script.
Who can provide some advices? Thanks very much in advance.

Which is better? in the past, our 10g data guard environment is not based on Oracle ASM. ASM provides a host of new features ito data management, and performance - to the extent that you can rip out the entire existing storage system, replace it with a brand new storage system, without a single second of database downtime.
Someone think if we adopt the oracle ASM, the shortcomings are :
1. as there is one more instance that will consume more memory and resource.Not really relevant on 64bit h/w architecture that removes limitations such a 4GB of addressable memory. On the CPU side... heck, my game PC at home has a 8 core 64bit CPU. Single die and dual core CPUs belong to the distant past.
Arguing that an ASM instance has overheads would be silly. And totally ignores the wide range of real and tangible benefits that ASM provides.
2. as the ASM file system cannot be shown out on the OS level directly such as "df" command, the disk utilization monitor job will be more difficult. at least it cannot be supervised at OS level.That is a A Very Good Thing (tm). Managing database storage from o/s level is flawed in many ways.
3. as the DB bshoule be done the daily incremental backup (Mon-Sat) to Local Backup Drive. the bakup job must be done by RMAN rather than user-managed script.
rman supports ASM fully.
I have stopped using cooked file systems for Oracle - I prefer ASM first and foremost. The only exceptions are tiny servers with a single root disk that needs to be used for kernel, database s/w, and database datafiles. (currently these are mostly Oracle XE systems in my case, and configured that way as XE does not support ASM and is used as a pure cost decision).
