10g RAC on Blade Servers (HP C-Class)

All
Just wanted to know anyone's take on deployment of 10g RAC on blade servers -
Challenges, recommendations, etc. Anyone out there deployed a mission critical oltp application running RAC on blade servers?
Appreciate a response
Thanks - KP

Have several RAC blade clusters. Not using HP's blades though. The biggest one (12 nodes) is over 2 years old. The only h/w issue during that time as far as I can recall, was a power supply that blew. Vendor replaced and it was business as usual.
We are btw replacing all our HP boxes (old L classes mostly) with blade clusters. Given the stability and robustness of our big cluster, and that of the blades we're using for development, web servers and stand-alone database servers (running SE), we've decided to make this our standard h/w architecture. Of course, financially this receives a lot of noddy points from the bean counters. ;-)

DELL BLADE Server and Windows 2003 Oracle 10g RAC

Anyone out there sucessfully set up a Windows 2003 Oracle 10g RAC using DELL BLADE Servers and VMWARE configuration?

dear guys
i have 3 database instances running on primary databases.means 3 different sid.now i want to create DR for same.is it possible.how can i do it.its like 3 versions production,trial and development database running on primary under same home.i want to make dr(standby) .so do i follow same proedure for all.
taking backups of all three.creaating pfile for all and then to start recovery for all three.is it possibleYes, It's called RAC but It need to be licensed.
You have a lot of manuals online so check by yourself how to install and configure.

ORACLE 10G 2 Node RAC on servers AB to 3 node 11GR2 RAC on new servers XYZ

Hi Gurus ,
We have a business requirement to upgrade existing oracle 10.2.0.4 2 Node RAC on servers A,B (HP UX 11.31 ) to 3 Node ORACLE 11GR2 on new Servers X,Y and Z(Linux and servers are from different vendor)
We don't have ASM.We have RAW file system
Now this has to be done with near zero down time.This is a very busy OLTP System.Golden Gate is not an option as Management is not going for it this time.
Storage is same for everything.I am thinking of the following ways.Please let me know if you have any better plan or if you want to correct my existing plan
Initially i thought of this way and i immediately answered myself
Plan A
1 ) Storage copy (BC etc..) exising 10g RAC Database files on A,B to new volumes allocated to Servers X,Y and Z ( I don't think it's possible as OS is different.I am not sure whether copying this way is possible or not , even if possible i am not sure whether new OS can identify these files or not)
2 ) upgrade 2 Node 10.2.0.4 on X,Y to 11GR2 .
3 ) Add a Database Node on Z
Plan B is
1) Build 3 Node brand new 11GR2 on X,Y and Z
2 ) Plan for how can you replicate the data ( This has to be a logical way)
a ) RMAN - Very time consuming as this is >50 TB Database
b) Golden Gate - Not an option.Even if we can use it , i see there are so many logical issues with golden gate
c) Expdp/impdp - forget about it :)
d) physical standby (Versions are different.If it is same version and Same OS then would have been best bet)
What would be the ideal way to do this with minium down time and with out golden gate
I think something can be done on the lines of PLAN A itself.
Requesting your help Gurus
Thanks

Hi,
Have you considered possibility to setup a logical standby and do rolling upgrade ?
Please have a look at the following:
1) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-transientlogicalrollingu-1-131927.pdf
2) http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-upgrades-made-easy-131972.pdf
If you can practice on test setup, it looks a faster option than the others.

MULTIPLE USERS 10G RAC ORACLE_HOME INSTALL WITH ASM/CRS

Hi,
We need to install multiple 10g RAC databases on a two node Sun servers. Below is our configuration:
1) Sun Solaris (ver 10) with Sun Cluster 3.2
2) One ASM/CRS install (by 1 OS account)
3) Four ORACLE_HOME 10g database install (by 4 different OS user accounts)
We would like to use one ASM instance for all four databases with appropriate privileges.
OS User:           OS Group
========      =========
oraasm           dbaasm - (ASM and CRS install owner)
ora1           dbaora1 - first db owner
ora2           dbaora2 - second db owner
ora3           dbaora3 - third db owner
ora4           dbaora4 - fourth db owner
I understand that certain privileges need to be shared between ASM/CRS and DB owners. Please let me know the steps to be followed to complete this install.
Thanks in advance.

Hi
Please read that: Documentation http://download.oracle.com/docs/html/B10766_08/intro.htm
- You can install and operate multiple Oracle homes and different versions of Oracle cluster database software on the same computer as described in the following points:
-You can install multiple Oracle Database 10g RAC homes on the same node. The multiple homes feature enables you to install one or more releases on the same machine in multiple Oracle home directories. However, each node can have only one CRS home.
-In addition, you cannot install Oracle Database 10g RAC into an existing single-instance Oracle home. If you have an Oracle home for Oracle Database 10g, then use a different Oracle home, and one that is available across the entire cluster for your new installation. Similarly, if you have an Oracle home for an earlier Oracle cluster database software release, then you must also use a different home for the new installation.
If the OUI detects an earlier version of a database, then the OUI asks you about your upgrade preferences. You have the option to upgrade one of the previous-version databases with DBUA or to create a new database using DBCA. The information collected during this dialog is passed to DBUA or DBCA after the software is installed.
- You can use the OUI to complete some of the de-install and re-install steps for Oracle Database 10g Real Application Clusters if needed.
Note:
Do not move Oracle binaries from one Oracle home to another because this causes dynamic link failures.
. If you are using ASM with Oracle database instances from multiple database homes on the same node, then Oracle recommends that you run the ASM instance from an Oracle home that is distinct from the database homes. In addition, the ASM home should be installed on every cluster node. This prevents the accidental removal of ASM instances that are in use by databases from other homes during the de-installation of a database's Oracle home.

Oracle 10g RAC

Hi All,
I am a research student currently struggling to install Oracle 10g RAC on Windows OS.What i understand about a Oracle RAC database system is that it involves a configuration of multiple hosts or servers joined together with a clustering software and accessing the shared disk structures.What i also understand is that i need a CRS provided by Oracle for a Windows or Linux based RAC installation.
What i don't understand is for a Two node RAC system do i need a Third machine which has the shared storage device.If yes do i have to install a copy of Oracle 10g Enterprise Edition and CRS on the shared storage device moreover do i need to install a copy of Oracle 10g Enterprise edition on each of the nodes or just the clusterware is enough.

Hi Salil
No, you do not need a third machine. You can even setup RAC as a single node on one machine! What you do need is to have some sort of cluster aware file system. Try looking at OCFS on Windows in your case.
If you are interested in a Linux example please have a look at the examples at http://ocpdba.net/oracle9i_rac/cheaprac.html and http://ocpdba.net/oracle10g_rac for an OCFS implementation I am working on.

Ahbaid

Oracle 10g RAC using ASM - Storage Issue

I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft     10 Gb          OCFS2 File system
/oracrs          2 Gb          OCFS2 File system
/orabackup      100 Gb          OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??

Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC

I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
DirectToField scriptMapping = new DirectToField();
scriptMapping.setAttributeName("script");
scriptMapping.setFieldName("IMAGE.SCRIPT");
descriptor.addMapping(scriptMapping);
As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
The tip also states to call the following code in case of using Clob:
DatabaseLogin login = session.getLogin();
login.useStringBinding();
Should the above 2 lines of code be called after the following lines of code?
SessionManager sessionManager = SessionManager.getManager();
Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
Appreciate any help.

Never mind ....... I had already figured it out .....

NIC ROUTER requirement for 10g RAC database

I need to know what hardware to order in setting up an 10g RAC database without a single-point-of-failure. My question centers on the networks. If each server has one NIC for the public interface and one NIC for the private interconnect, aren't the routers these NICs are attached to a single point of failure? If each server has two NICs bonded together for the public interface and two NICs bonded together for the private interconnect, does each NIC attach to a different router?

is RDMA and infiband ar same??Infiniband is a switched fabric layer for high speed communication. RDMA is a protocol for "+remote direct memory access+".
Infiniband supports the Internet Protocol suite over Infiniband, or IPoIB. It also supports RDMA over Infiniband.
so do we need only infiband SDR / QDR switch to set infiband OR what else??You need an Infiniband switch - Cisco and Voltaire are two companies that supply this type of hardware. The latter is used by Oracle in its Exadata database machines. Unsure about Cisco's commitment to Infiniband switches as they have discontinued their Infiniband switches with integrated fibre channel gateways. A sore point with us after we bought into this technology about 2 years ago, in part on their very own recommendations - and now own very expensive, somewhat buggy and totally unsupported hardware. Seems like the new Cisco California servers are GigE and not Infiniband, which perhaps explain this (flawed) decision of theirs...
For each cluster node, you need an Infiniband PCI card (typically has 2 ports). If you are going to use bonding, you will need a pair of Infiniband cables per server. Also remember to get spares - both PCI cards and cables.
If you want redundancy at the switch, you need to get yourself 2 Infiniband switches.
But if you're planning to invest this into a RAC cluster, then surely you should also invest money in RAC licensing and support - and with that gain access to very useful documentation like the RAC Starter Kit and so on.

Solaris 10 and Hitachi LUN mapping with Oracle 10g RAC and ASM?

Hi all,
I am working on an Oracle 10g RAC and ASM installation with Sun E6900 servers attached to a Hitachi SAN for shared storage with Sun Solaris 10 as the server OS. We are using Oracle 10g Release 2 (10.2.0.3) RAC clusterware
for the clustering software and raw devices for shared storage and Veritas VxFs 4.1 filesystem.
My question is this:
How do I map the raw devices and LUNs on the Hitachi SAN to Solaris 10 OS and Oracle 10g RAC ASM?
I am aware that with an Oracle 10g RAC and ASM instance, one needs to configure the ASM instance initialization parameter file to set the asm_diskstring setting to recognize the LUNs that are presented to the host.
I know that Sun Solaris 10 uses /dev/rdsk/CwTxDySz naming convention at the OS level for disks. However, how would I map this to Oracle 10g ASM settings?
I cannot find this critical piece of information ANYWHERE!!!!
Thanks for your help!

You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

10g RAC on Solaris 10 containers - Question on Approach

Hi All
To introduce a little, I am trying to set-up 10g RAC (active-active) on Solaris 10 Containers. For the disaster recovery site, I was considering an option for storage replication across datacenters. As I look at the situation where the database could be highly transactional, I wanted to go for this option hoping I might be better able to recover db on dr site if a failure happens and also alleviate some load from the prod servers. In this regard I have a set of questions for which if you could share your experiences, thoughts .. I am sure will help my preperation.
1 Is Oracle Supported on Solaris 10 containers? I believe it is not supported and ofcourse am getting into the certification matrix for this with oracle. Anyways, any work around tried out by anyone ?
2 Which product is better in terms of performance while co-existing and co-functioning with Oracle? Sun Cluster!!! Vertas Cluster!!! any other? I am unable to link to any recommendations from Oracle and hence trying to understand the generic or say standard approach to this.
3 I understand on Prod site, Oracle remains active-active on two node cluster while I will mirror my SAN between Prod site and DR site on a timely basis, while DB is up and running. This mirroring has to be only an asynchronous mirroring for some limitations. I am unsure about my recoverability if we need to switch over to DR. Will I be able to recover the Database to a point when my last mirroring has been completed successfully when I say the mirroring happened while the Prod db is up and running (hot backup type on disk level). Until now I used a cold backup for Storage replication and I was sure to bring it up there. This hot backup kind of attempt is raising unrest and questions about the abilities.. :-(
4 I also have come across a term called federated databases? Is it similar to what I am trying to achieve here? Storage level replocation across data centres?
I know it takes some time to get to the end of it and finally implement it, but your inputs will certainly help me get things straight before I hit this first click. Thanks for all your inputs, advices, suggestions. :-)
Regards!
Sarat

According to Oracle "Both Oracle 9i R2 and 10g R2 databases have been certified to run in a Solaris Container."
There are references here :- http://forums.sun.com/thread.jspa?threadID=5397695
"Oracle databases (RAC and non-RAC) have been certified to run in a global Solaris 10 Container"
What storage are you using ? (filesystem, ASM ?) Personally I prefer ASM now, but it does depend on the storage platform and backup strategy.
What backup infrastructure do you have ? RMAN backup directly to tape is better than file copy.
For DR standby purposes I would use Dataguard instead of disk mirroring / storage replication. It is much more flexible (e.g can switch direction of replication, do incremental backups from the standby etc).
I would use CRS instead of VCS. CRS is built for the job, and integrates with netca, dbca, etc for service management, and also integrates with Dataguard Broker for standby switchover.

Regarding Services in Oracle 10g RAC

Hi All,
We are having Oracle 10g RAC (10.2) on Linux machines. We don't have any services configured failover. This can be visible from srvctl config database -d, as nothing related services information is displayed.
I even checked failover_type and Failover_method from GV$session and for all it's showing None. We have only default database service (same as database name).
My question is:
Can I modify/configure this default service as failover/loadbalance enabled using srvctl? If so, please let me know.
PS: I can't provide any output here as our client network doesn't permit copying.
Regads,
Kumar

Seeking a solid reccomendation concerning 10g RAC implementation.

I need a solid recommendation regarding what hardware I should use for my planned Oracle 10g RAC environment.
Currently, I am looking for both node and SAN recommendations.
I also created a list of 11 questions that I need to have answered.
Here is how this will be configured:
3 Node Oracle 10g RAC
Each Node will consist of:
32Gb of RAM (minimum)
Windows 2003 64-bit Enterprise (corporate standard, but I can go with Windows 2008 if I have a valid justification)
74Gb RAID 1 (minimum)
Dual 10Gb Ethernet NICs
The SAN will consist of:
750Gb-3Tb dedicated to Oracle
10Gb Ethernet NICs
Here are some of my general questions:
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
I will consider all input of high value, so please let me know what you would recommend.
Thank you for your time.

please find answers that i know for some questions.
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
=> what is the backup method you will be using? certainly recommend RMAN (in addition to OS backups that you are planning to use) for block recovery, should there a block corruption.
i would keep some copies on the SAN local and mirror to DR site too.
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
=> do not suggest thin provisioning for production.
how big the volumes are going to be? reason for asking the Q is, if the volumes are going to be in TB, percentages can be lower. please plan for 2 years atleast.
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
=> have beetween 75GB to 100GB. hope you are going to have only ORACLE RDBMS and CRS software in here.
please make sure that you rotate your listener logs and alert logs and regular removal of old .trc files older than certain number of days old.
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
=> node usage will help from CPU standpoint only. what about the disk writes it is going to perform to the data files?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
=> attend a 5 day course from Oracle. install RAC on own and play with it.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
=> did not compare, though installed 11g.
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
=> running on windows? please do not. used on linux a lot. pretty stable and solid. recommend to go with 10.2.0.4 or higher.
hope the above will help.

Shared Storage allocation for Oracle 10g RAC

Hi,
I am about to implement a Two Node Oracle 10g RAC on Windows 2008 (32-Bit) servers. We are going to use EVA4400 storeage and we have 600 GB for Oracle RAC and database.
I intend to follow the steps given in RACGuides_Rac10gR2OnWindows.pdf mentioned in Note 811271.1 (RAC Assurance Support Team: RAC Starter Kit and Best Practices (Windows)).
I would like to know how should I allocated the storage for OCR,Vote, Database and Flash Recovery Area. Meaning how many LUNs and of what size to be created and presented to both the servers. To start with I need to create a 25 GB database. We will be using Raw Device for OCR and Vote and ASM for Database and Flash Recovery Area.
Please advice.
Thanks,
Thiru

I am about to implement a Two Node Oracle 10g RAC on Windows 2008 (32-Bit) servers. Oracle 10g on Windows 2008 is not supported. Anyway installing a cluster as of today i would use a 64-bit operating system together with a 64-bit database. Everything else is not state-of-the-art anymore.
As of today i would go with 11g Release 1 (11.1.0.7.0) plus latest patches for Clusterware and ASM. Because you are using Windows 2008 you must use 11g Release 1 for the database as well. Bear in mind that Windows 2008 R2 is at this point in time not supported for 11g R1 or 11g R2 either.
I would like to know how should I allocated the storage for OCR,Vote, Database and Flash Recovery Area. Meaning how many LUNs and of what size to be created and presented to both the servers. This is said in the installation documents. Rule of thumb: At least three LUNs of 2 GB for OCR and three LUNs of 2 GB for Voting disk.
To start with I need to create a 25 GB database. We will be using Raw Device for OCR and Vote and ASM for Database and Flash Recovery Area.According to Oracles recommendations: Two disk groups: one for database files, the other for the flashback area.
But your setup may be different (more disk groups,....)

Job Scheduling on Oracle 10g RAC

Hi,
If I want to run job on Oracle 10g RAC database having 2 instances suppose n1 and n2 separately and both instances are working/using same Service Name then how could i do this ??
or how to use SID instead of Service Name in Job Class ???
Please guide..... Replay awaited...........

Priyanka,
If you are a newcomer to the DBA, I would strongly suggest to invest at least time(if not money for training) in reading documentation related to fields in which you are working. For RAC, this should be a good start( V10.2) ,
http://download.oracle.com/docs/cd/B19306_01/rac.102/b14197/toc.htm
can we use these dynamic views in Procedure The counter question is, why? What exactly are you trying to accomplish? If you can tell us this, there may be a better way we may suggest doing that thing?
