Using ZFS for Oracle RAC 11gR2 binaries

Hi,
We have following scenario,
Two Node Cluster: Oracle RAC 11Gr2 with Clusterware on Solaris 10
We want to keep Oracle & Clusterware binaries on ZFS mirror file system on each node locally and for Data files, FRA, Voting disks & OCR on shared SAN using ASM.
My question, is the above scenario certified by Oracle or can we keep Oracle binaries on ZFS...?
Will appreciate your input.
Thanks

Well my confusion started after reading this doc on oracle support:
Certification of Zeta File System (Zfs) On Solaris 10 for Oracle RDBMS [ID 403202.1]
"Oracle database 10gR2 (10.2.0.3 and higher patches), 11gR1 (11.1.0.6 and higher patches) and 11gR2 (11.2.0.1 and higher patches) are certified with Solaris 10 ZFS on Sparc 64-bit and Solaris x84-64. See Solaris ZFS_Best_Practices_Guide. This is for single instance ONLY. ZFS is currently not applicable to RAC and not Certified to use it as a shared filesystem."

Benefits vs Disadvantages of using DNS for Oracle RAC (12c or 11g)

For nearly all of my Oracle RAC Builds, I've used /etc/hosts and not DNS. As such I've not been able to take full advantage of GNS and SCANS.
Please note some of your experiences associated with the benefits of using DNS configuration for your Oracle 12c RAC Builds. I'm building my 12c RAC now and I'm starting to configure DNS so that I can provide my customers with better value/add of High Availability. I've used /etc/hosts in the past and one of my arguments in using /etc/hosts can be more secure because you only put in the /etc/hosts what you want the node to know. I also beleave that using /etc/hosts is a lot more simple and perhaps that could be a potential vulnerability. I've decided to start using DNS and to learn how to make it secure.
Your experiences are appreciated. Thanks in Advance!

I see no disadvantages using DNS.
What happens with your clients if your DNS goes down? It stop working?
What is the cost to manage the host files from all host desktop and servers?
I see no reason to not use DNS.
> For nearly all of my Oracle RAC Builds, I've used /etc/hosts and not DNS. As such I've not been able to take full advantage of GNS and SCANS.
Wrong... Full advantage of Clusterware, because is not supported use GNS or SCAN without a DNS.

Why do we use reverse proxy for Oracle RAC Cluster setup

Hello All,
I got this question lately.. "why do we use reverse proxy for Oracle RAC Cluster setup". I know we use the reverse proxy at Middleware level for multiple security reasons.
Thanks..

"why do we use reverse proxy for Oracle RAC Cluster setup".
I wouldn't. I wouldn't use a proxy of any sort for the Cluster Interconnect for sure.
Cheers,

ASM pfile lost in Oracle RAC 11gr2

Hello Gurus,
I am new to Oracle RAC 11gr2 and facing some issues. our spfile/pfile for asm instance is lost and I am not able to startup the asm instance.
Environment is as below:
RAC 2 nodes
Oracle RAC 11gr2

Hi,
Do we need to Set variable ORACLE_HOME properly (Grid Home) while starting RDBMS instance?
e.g ORACLE_HOME=/u01/app/11.2.0/grid*I recommend you set ORACLE_HOME properly for each Oracle Installation when you use SQLPLUS.
i.e: cat /etc/oratab
orcl:/u01/app/oracle/product/11.2.0/db_1
db10g:/u01/app/oracle/product/10.2.0/db_1
+ASM1:/u01/app/11.2.0/gridAlso you can startup/shutdown our database with SQLPLUS using ORACLE NET*, but it must be configured properly.
My recommendation <s>is always</s> use SRVCTL and CRSCTL to manage to your environment. Track all the process of initialization processes through the logs using ADRCI utility (only 11.1 or later).
When use SRVCTL or CRSCTL to manage I recomend you use (GRID HOME).

SQL>I give to you three options:
1° - Add more asmdisk on Diskgroup +FRA
2° - Make backup of all archivelog using RMAN and option delete input (i.e backup archivelog delete all input;)
3° - If this database is for TEST ONLY and you not need backup or recovery of then you can delete all archivelog using RMAN (i.e delete archivelog all;)
I recommend you create routine of backups of the database and archivelog to prevent this area becomes exhausted.
If you need the database in archivelog but it is only to test then create routine to delete archivelogs periodically.
If you dont need the database in archivelog, then just disable it.

Is OCFS2 certified with oracle RAC 11gR2 ?
Thanks..

ocfs2 is certified for oracle 11gr2 but oracle recommends using asm. please see this for more information http://download.oracle.com/docs/cd/E11882_01/install.112/e10812/storage.htm#CWLIN262

Is it possible to install Oracle RAC (11gR2)on server having just one NIC ?

Hi all,
Please let me know if it is possible to install Oracle RAC (11gR2) on server having just one NIC card on linux (RHEL5.8).
by creating a virtual NIC like the real ethernet is etho and we are creating eht0:1 as virtual NIC, and i want to use this as eth1, so please suggest me if this is the workaround for my issue or not.... if not please suggest me the best way to install RAC on physical linux box running with one NIC card.
Thanks

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Gig Ethernet V/S SCI as Cluster Private Interconnect for Oracle RAC

Hello Gurus
Can any one pls confirm if it's possible to configure 2 or more Gigabit Ethernet interconnects ( Sun Cluster 3.1 Private Interconnects) on a E6900 cluster ?
It's for a High Availability requirement of Oracle 9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster interconnect for Deploying Oracle RAC on E6900 ?
2) What is the recommended Private Cluster Interconnect for Oracle RAC ? GiG ethernet or SCI with RSM ?
3) How about the scenarios where one can have say 3 X Gig Ethernet V/S 2 X SCI , as their cluster's Private Interconnects ?
4) How the Interconnect traffic gets distributed amongest the multiple GigaBit ethernet Interconnects ( For oracle RAC) , & is anything required to be done at oracle Rac Level to enable Oracle to recognise that there are multiple interconnect cards it needs to start utilizing all of the GigaBit ethernet Interfaces for transfering packets ?
5) what would happen to Oracle RAC if one of the Gigabit ethernet private interconnects fails
Have tried searching for this info but could not locate any doc that can precisely clarify these doubts that i have .........
thanks for the patience

Can any one pls confirm if it's possible to configure
2 or more Gigabit Ethernet interconnects ( Sun
Cluster 3.1 Private Interconnects) on a E6900
cluster ?Yes, absolutely. You can configure up to 6 NICs for the private networks. Traffic is automatically striped across them if you specify clprivnet0 to Oracle RAC (9i or 10g). That is TCP connections and UDP messages.
It's for a High Availability requirement of Oracle
9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster
interconnect for Deploying Oracle RAC on E6900 ? Yes, definitely.
2) What is the recommended Private Cluster
Interconnect for Oracle RAC ? GiG ethernet or SCI
with RSM ? SCI is or is in the process of being EOL'ed. Gigabit is usually sufficient. Longer term you may want to consider Infiniband or 10 Gigabit ethernet with RDS.
3) How about the scenarios where one can have say 3 X
Gig Ethernet V/S 2 X SCI , as their cluster's
Private Interconnects ? I would still go for 3 x GbE because it is usually cheaper and will probably work just as well. The latency and bandwidth differences are often masked by the performance of the software higher up the stack. In short, unless you tuned the heck out of your application and just about everything else, don't worry too much about the difference between GbE and SCI.
4) How the Interconnect traffic gets distributed
amongest the multiple GigaBit ethernet Interconnects
( For oracle RAC) , & is anything required to be done
at oracle Rac Level to enable Oracle to recognise
that there are multiple interconnect cards it needs
to start utilizing all of the GigaBit ethernet
Interfaces for transfering packets ?You don't need to do anything at the Oracle level. That's the beauty of using Oracle RAC with Sun Cluster as opposed to RAC on its own. The striping takes place automatically and transparently behind the scenes.
5) what would happen to Oracle RAC if one of the
Gigabit ethernet private interconnects fails It's completely transparent. Oracle will never see the failure.
Have tried searching for this info but could not
locate any doc that can precisely clarify these
doubts that i have .........This is all covered in a paper that I have just completed and should be published after Christmas. Unfortunately, I cannot give out the paper yet.

Copper cable / GigE Copper Interface as Private Interconnect for Oracle RAC

Hello Gurus
Can some one confirm if the copper Cables ( Cat5/RJ45) can be used for Gig Ethernet i.e. Private interconnects for deploying Oracle RAC 9.x or 10gR2 on Solaris 9/10 .
i am planning to use 2 X GigE Interfaces (one port each from X4445 Quad Port Ethernet Adapters) & Planning to connect it using copper cables ( all the documents that i came across is been refering to the fiber cables for Private Interconnects , connecting GigE Interfaces , so i am getting bit confused )
would appretiate if some one can throw some lights on the same.
regards,
Nilesh Naik
thanks

Cat5/RJ45 can be used for Gig Ethernet Private interconnects for Oracle RAC. I would recommend trunking the two or more interconnects for redundancy. The X4445 adapters are compatible with the Sun Trunking 1.3 software (http://www.sun.com/products/networking/ethernet/suntrunking/). If you have servers that support the Nemo framework (bge, e1000g, xge, nge, rge, ixgb), you can use the Solaris 10 trunking software, dladmin.
We have a couple of SUN T2000 servers and are using the onboard GigE ports for the Oracle 10gR2 RAC interconnects. We upgraded the onboard NIC drivers to the e1000g and used the Solaris 10 trunking software. The next update of Solaris will have the e1000g drivers as the default for the SUN T2000 servers.

Solaris 10 patches for Oracle Database 11gR2

Hi,
I downloaded Oracle Solaris 10 s/w from e-Delivery and got it installed. For Oracle Database 11gR2 I also need the followging patches:
120754-06: SunOS 5.10_x86 libmtsk
119961-05: SunOS 5.10_x86: Assembler
119964-14: SunOS 5.10_x86 Shared library patch for C++_x86
Though we have access to MyOracleSupport we can only download s/w patches using our support contract with Oracle and not OS patches.
Is there any other way I can get these patches.
Rgds,
Thiru.

Thiru,
You won't find the patches in the patches/ directory on the DVD or the ISO image. Oracle integrates the patches directly into the packages, so there is no need to provide or install them separately.
All patches have a patch number (e.g. 120754) and a revision (e.g. 06). A newer revision of a patch always contains all fixes of the previous revisions. So try to run "showrev -p | grep 120754" instead, and you'll see that patch 120754-08 is pre-installed. As revision 08 is newer/higher than 06, the patch requirement is satisfied.
Hope that helps,
mp.

Any Oracle best practice/standards for inter-DataCente links for Oracle RAC

Hello Oracle Experts,
Am working for a customer to set up Oracle RAC architecture hosting SAP/Non-SAP applications per SLA levels(MC/BC/Standard) specs. Currently my network team needs calculation to arrive at whether we will go for a (1), (2) or (3) 10Gig links for inter DC (Data-Center) for Oracle RAC.. below is additional background:
•     Porting all client SAP/Non-SAP Oracle databases to new 2 data-centers.
•     There will be 10 blades (4x BL680s and 6x BL460s) in each DC (can scale-up/out later on).
•     Clusters architecture to support Extended/Stretched RAC cluster feature
•     Clusters 2-node each(1-datacenter1, 1-datacenter2) and nodes distributed across 2 x c7000 such that no cluster has more than one node in an enclosure.
•     Each node will have - 4 NIC ports ( 2 x public and 2 x private) , 2 dual-port HBA
•     Oracle ASM/ACFS (ASM Cluster File System), Voting Disk, OCR and Database files
•     the versions are Oracle 11g RAC, Oracle 10g RAC and Oracle 9i (for DataGuard/Standby) on RHEL 6 on Proliant Blades (x86) + BladeMatrix
My network colleagues considering using DWDM across the 2 DCs(given the lesser cost?). Am still looking around if there are any Oracle/industry-best practices around this and having a calculation to support that..
Many Thanks in advance..
Regards,
Abhijit

Hi ,
There are no specific set of steps / practices for batch loading contents to ucm . It would be very much dependent on how many contents does the user have to load to UCM and how well the server is configured in terms of performance .
You can get more details from the following documentation link : http://docs.oracle.com/cd/E21043_01/doc.1111/e10792/c02_settings009.htm

If use MSSQ , when oracle rac node reboot, client get TPEOS error

Hi, all
in my tuxedo applicaton, if we use Single Server, Single Queue mode , when reboot any Oracle RAC node, our application is ok, client can get correct result. but if we use MSSQ（Multi Server, Single Queue) , if Oracle RAC node is ok , our application also is ok. but if we reboot any Oracle RAC node, client program can continue run, get correct result, but always get TPEOS error , for this situation， server can get client request, but client can not get server reply, only get TPEOS error.
our enviroment is :
oracle RAC ,10g 10.2.0.4 , two instances ,rac1 rac2, and two DTP services s1 and s2, set s1 and s2 services TAF is basic
tuxedo 10R3 , two nodes ,work in MP model ，use XA access oracle rac database，services have Transaction and not Transaction
OS is linux AS4 U5, 64bits
service program use OCI
can any one encounter this problem ?

Hi, first thanks you
in ULOG file , only have failover information, not any other error message, in client side also has no other error.
not use MSSQ, ubb file about MSSQ config

Considering shared storage for Oracle RAC 10g

Hi, guys!
My Oracle RAC will be run on VMware ESXI 5.5. So, both 2 nodes and shared storage are on VM. Don't blame for this, I dont have another choice.
I am choosing shared storage for Oracle RAC. I am choosing between NFS and ISCSI server, both can be done in RedHat linux or FreeNAS.
Can u, guys, help me to do the choise?
RedHat or FreeNAS
ISCSI or NFS
Any help will be appreciated.

NFS is really easy. Create your zero-filled files, set the ownership and access modes, and point your asm_diskstring at them. Much simpler than configuring an iSCSI target and initiators, and then messing about with ASMlib or udev.
I recorded a public lecture that (if I remember correctly) describes it here, Oracle ASM Free Tutorial
I will be using OCFS2 as cluster FS. Does it make any difference for NFS vs ISCSI?

Need clarification for firmware & MPIO version for Oracle RAC

Dear All,
We have two-node Oracle RAC configuration 10gR2, Windos 2033 R2, 64-Bit OS using ASM and Oracle 11gR1 clusterware on HP Blades. The SAN storage is from IBM. We want to upgrade the firmware and MPIO version as per vendor recommendation.
Is there any requirement for Oracle RAC to have specific version of firmware and MPIO? Is there any matrix available for this? Or is it like both nodes should be able to see same SAN storage (LUN) irrespective of version used?
Thanks

Please note that Oracle RAC doesnt have requirement any sepcific firm ware. If you upgrade the firmware, it should not break any existing config, so pls check with IBM.
Also if you are doing any specific firmware upgrade then IBM should provide the supported version list.
Hope this help,
Regards

Adding Box for Oracle RAC(Clustering) to BIW 3.5 Oracle/Linus

Hai Gurus,
Suppose if we have 1 box with Bw3.5 Linux/Oracle and add another box to do Oracle RAC(clustring). Do we need to re-instal the Box 1 also or we can do that with small configuration changes.
Guide me.
Regards,
Mano

Hi Mano
As in most cases there is a short answer and a longer one. Short:
If your system is RAC ready, switching from single instance to cluster database and adding a new node is quite simple. From pure application side there will not be major changes necessary.
Long:
What do i need for oracle RAC, what do i have to do to make my system RAC ready?
Hardware / OS
You will need shared disks, cluster fs, on linux mostly OCFS2. If you don't have it yet, you need to get it and move your database on to it. You would probably need an additional lan interface for the interconnect.
Oracle / Database
You would have to install CRS, that is the oracle cluster software. Your oracle instance, listener will run as services controlled by CRS when RAC is enabled. You will need to configure separate redo threads and undo tablespaces for each node you add. Not least you would probably need an additional costly RAC extension license from your favorite oracle sales rep.
SAP
You should think about separate enqueue server and enqueue replication, although this is not mandatory. This is dependent on your reasons for using RAC. If it is high availability you should go for it.
This is not a complete list, i just wanted to give you an initial idea, please ask if you need further details. If you start into RAC just now, you will have a long way to go, otherwise the short answer will apply.
Best regards
Michael
