RAC Functionnality
I'm new with oracle RAC 10g and I plan to implement it.
I want to install RAC on DB1 and DB2 that access the same data on SAN storage. Is it possible to use DB1 for OLTP application and DB2 for the reporting?
Regards
Are DB1 and DB2 supposed to be different databases? Different servers? Something else?
You can with RAC have a single database with instances on two separate servers. You could then have separate services on different nodes for OLTP and reporting users. You would have to share the same database, so you'd have the same data model, which may or may not be appropriate for your reporting needs.

Where to place Agents if targetting to RAC
Can anyone advice best plactices where to put agents in RAC environment? Let's say that we've this environment:
- Source1: DB2
- Source2: Files
- Target: 4 nodes Oracle RAC
Also, we would like to use the road-balancing functionnality by ODI Agent; therefore, is it recommended to put agents on each nodes?
RegardsHello,
Locating the agent in that case really depends on how you'll load the target.
I guess that you'll use Oracle as the staging area and use SQL Loader KMs for moving data into Oracle.
In that case, locating the agent on the target is relevant, and if you use load balancing, balancing also the agent load on the different machines may help.
Best,

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. -
Error while running runcluvfy.sh(11g RAC on CentOS 5(RHEL 5))
Oracle Version: 11G
Operating System: Centos 5 (RHEL 5) : Linux centos51-rac-1 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux
Question (including full error messages and setup scripts where applicable):
I am attempting to install oracle 11g in a RAC configuration with Centos 5 (redhat 5) as the operating system. I get the following error
ERROR : Cannot Identify the operating system. Ensure that the correct software is being executed for this operating system
Verification cannot complete
I get this error message when I run runcluvfy.sh, to verify the my configuration is clusterable. I don't know why.
I edited the /etc/redhat-release and entered echo "Red Hat Enterprise Linux AS release 4 (Nahant Update 7)" to attempt to fool the installer into thinking its red hat 4.
But still shows the same message.
Anyone knows how to fix this ?
Please help me.http://www.idevelopment.info/data/Oracle/DBA_tips/Linux/LINUX_20.shtml
runcluvfy.sh will not work on centos because the cluster verification utility checks the operating system version using the redhat-release packag and centos do this with his packages, so you must install and use redhat-release package
Get rpm-build to be able to build rpm’s:
[root@centos5 ~]# yum install rpm-build
Get source rpm of redhat-release
[root@centos5 ~]# wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/redhat-release-5Server-5.1.0.2.src.rpm
Build package:
[root@centos5 ~]# rpmbuild –rebuild redhat-release-5Server-5.1.0.2.src.rpm
Install newly generated rpm:
[root@centos5 ~]# rpm -Uvh –force /usr/src/redhat/RPMS/i386/redhat-release-5Server-5.1.0.2.i386.rpm -

How to install 11gR2 RAC on 64 bit linux OS
I am completely new to this topic of RAC and need to be installing and standing up RAC on Linux 64 bit OS . I have good knowledge of installing oracle database ENTERPRISE version 11gR2.
Can you guide me as to how to start. I am looking for leads. Probably we will have 2 nodes.
Thank you very much for helping me in advanceIf you are a My Oracle Support (Metalink) user, go check out these two notes created by the Oracle RAC Assurance Team. They are excellent.
NOTE: 810394.1 RAC Assurance Support Team: RAC Starter Kit and Best Practices (Generic)
NOTE: 811306.1 RAC Assurance Support Team: RAC Starter Kit (Linux)
In the Linux note mentioned above there is a link to a Linux Step by Step Instruction Guide. This step by step instruction guide is the best start to finish document I've seen for how to set-up and install Oracle RAC. I believe the guide is written for installing release 11.2.0.2. -
In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?
The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

RMAN, RAC, NFS, and server lock ups
Good day. My environment is:
--a 2-node RAC
--Enterprise Edition 11.2.0.3
--RHEL 5.1
The goal is to use RMAN to push backups to a shared NFS mount (on a different server). Both nodes will have access to this location (in the event one node goes down, the other can still run backups). Easy, right?
Wrong.
I've tried every NFS mount option in the book. Most work just fine, some don't. When I use the recommended NFS mount options:
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp, vers=3,timeo=600, actimeo=0
or
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,noac,forcedirectio, vers=3,suid
The mount works normally. I can "ls" and "mkdir" and "touch" and "vi" and "cp" files back and forth from the NFS backup location to the RAC node all day long. No problems. However, when I try to do almost anything in RMAN which requires writing to the NFS backup location such as the command "backup archive all delete input;" (or even things as simple as a Crosscheck or RMAN configuration change which writes any changes back to the autobackup ControlFile) the node locks up. There are no errors (or if there are, I don't know where to find them), even when I use RMAN log.
Just to recap: I run a Crosscheck (or any RMAN process that writes to the NFS backup location), the node will lock up, and I can let it sit for a day, inaccessible, with CRSCTL on the other node saying it's offline, and the node will never come out of a "frozen" state. It cannot be pinged or connected to.
I think I can safely rule out NFS mount options at this point.
I understand (after extensive reading of MOS docs and testing) that RAC RMAN can and does suffer from inefficient I/O when writing to an NFS mount. I don't think that's the culprit either. The autobackup ControlFile is not that big and I cannot see how running a simple Crosscheck would lock an entire node.
I am hoping someone has encountered this in the past and hopefully it's just a simple misconfiguration somewhere.My NFS line in /etc/fstab is (these options are for supporting 11.2.0.3, 11.1.0.7, and 10.2.0.4/5 simultaneously): server.domain:/NFS_Export /backup nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 0 0
Before you installed GI, did you by chance do a yum update? I've encountered a similar issue which ended up being due to mkinitrd creating a corrupted kernel; mkinitrd is invoked during the GI installation when the ADVM drivers are added and in my case mkinitrd created a new kernel prior to the new kernel being installed. Second to that, make sure you have the matching kernel headers to your kernel version. If they are different then you could probably get away with just creating a new kernel with mkinitrd and relinking GI/RDBMS homes, but be prepared to wipe GI and reinstall. -

Edited by: 1001408 on Apr 21, 2013 9:22 AMHello guys finally i find mistake i was doing
while configuring Public Ip for the nodes i was not giving Default Gateway .I was assuming as all these machine is in same network with same Ip range so they would not be needing Gateway but here my assumption mismatch with oracle well finally happy to see 11G r2 with GNS running on my personal laptop.

Oracel 11gR1 RAC Cluster issue
We have 2-node Oracle 11gR2 RAC on HP-UX 11.31 environment. It was running lase 2 month without any issue.
We got some netconfig issue, and node-1 got rebooted today. after the reboot cluster didn't not start on node-1, database is running on node-2.

Edited by: ManoRangasamy on Jul 5, 2011 6:38 PMHi,
Please post the alertlog ASM from node 1, crsd.log and ocssd.log from node 1
It might be because node 1 can't see asm disk or permission accidentally changed when the node rebooted

What could be the issue ????

Do response ASAP...... Thanks
Regards,
ManishThanks Sebastian for your input.
yes. my lan2 is used for Cluster_interconnect which is having subnet 255.255.255.240.
Below are IPs used for RAC
Public
Node1: 10.10.1.173/255.255.240.0
Node2: 10.10.1.174/255.255.240.0
Private
Node1: 10.10.16.50/255.255.255.240
Node2: 10.10.16.51/255.255.255.240
Virtual
Node1: 10.10.1.191/255.255.240.0
Node2: 10.10.1.192/255.255.240.0
SCAN (Defined in DNS)
10.10.1.193/255.255.240.0
10.10.1.194/255.255.240.0
10.10.1.195/255.255.240.0
As you said, I will scrap GI Software again & will try with 255.255.255.0.
I Believe this Redundant Interconnect and ora.cluster_interconnect.haip present in 11.2.0.2.0 Version.
Oracle says:
Redundant Interconnect without any 3rd-party IP failover technology (bond, IPMP or similar) is supported natively by Grid Infrastructure starting from 11.2.0.2. Multiple private network adapters can be defined either during the installation phase or afterward using the oifcfg. Oracle Database, CSS, OCR, CRS, CTSS, and EVM components in 11.2.0.2 employ it automatically.
Grid Infrastructure can activate a maximum of four private network adapters at a time even if more are defined. The ora.cluster_interconnect.haip resource will start one to four link local HAIP on private network adapters for interconnect communication for Oracle RAC, Oracle ASM, and Oracle ACFS etc.
Grid automatically picks link local addresses from reserved 169.254.*.* subnet for HAIP, and it will not attempt to use any 169.254.*.* address if it's already in use for another purpose. With HAIP, by default, interconnect traffic will be load balanced across all active interconnect interfaces, and corresponding HAIP address will be failed over transparently to other adapters if one fails or becomes non-communicative. .
The number of HAIP addresses is decided by how many private network adapters are active when Grid comes up on the first node in the cluster . If there's only one active private network, Grid will create one; if two, Grid will create two; and if more than two, Grid will create four HAIPs. The number of HAIPs won't change even if more private network adapters are activated later, a restart of clusterware on all nodes is required for new adapters to become effective.
In my Setup, I am having Teaming for NIC's for Public & Private Interface. So I am thinking to break teaming of NICs because HAIP internally searching for next available NIC & not getting as all 4 are already in used with OS level NIC teaming.
My only Concern is, as I am going to change subnet for the Private IPs, should I change Private IP address ????
Thanks for the Support...

Findings and Recommendations
Finding 1: CPU Usage
Impact is 1.44 active sessions, 27.08% of total activity.
Host CPU was a bottleneck and the instance was consuming 99% of the host CPU.
All wait times will be inflated by wait for CPU.
Host CPU consumption was 99%.
Recommendation 1: Host Configuration
Estimated benefit is 1.44 active sessions, 27.08% of total activity.
Action
Consider adding more CPUs to the host or adding instances serving the
database on other hosts.
Action
Session CPU consumption was throttled by the Oracle Resource Manager.
Consider revising the resource plan that was active during the analysis
period.
Finding 2: Interconnect Latency
Impact is .07 active sessions, 1.33% of total activity.
Higher than expected latency of the cluster interconnect was responsible for
significant database time on this instance.
The instance was consuming 110 kilo bits per second of interconnect bandwidth.
20% of this interconnect bandwidth was used for global cache messaging, 21%
for parallel query messaging and 7% for database lock management.
The average latency for 8K interconnect messages was 42153 microseconds.
The instance is using the private interconnect device "lan2" with IP address
172.16.200.71 and source "Oracle Cluster Repository".
The device "lan2" was used for 100% of interconnect traffic and experienced 0
send or receive errors during the analysis period.
Recommendation 1: Host Configuration
Estimated benefit is .07 active sessions, 1.33% of total activity.
Action
Investigate cause of high network interconnect latency between database
instances. Oracle's recommended solution is to use a high speed
dedicated network.
Action
Check the configuration of the cluster interconnect. Check OS setup like
adapter setting, firmware and driver release. Check that the OS's socket
receive buffers are large enough to store an entire multiblock read. The
value of parameter "db_file_multiblock_read_count" may be decreased as a
workaround.

So, please help me fix this issue
Thank youI had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps. -
APEX Application behaviour in a RAC setup
Hi
Caveat first: I'm pretty new to Oracle RAC and just looking into it as an option. We have an APEX application currently running in Oracle 11gR2 single node currently and are considering HA for this.
My question is: What would be the expected behaviour seen by a User of an APEX application, in the event of a node failure, when running with an OHS / RAC configuration? Will they get "transparent fail-over" and see nothing or will they see an error?
I appreciate I could post in the APEX forum, but feel that is probably more of a development forum and possibly someone here has had to look at things at this level.
I have read what I think may be the definitive reference for this:
http://www.oracle.com/technetwork/developer-tools/apex/learnmore/apex-rac-wp-133532.pdf
but while it covers most of what I want I don't believe I have found an answer to my question
This states:
"The Transparent Application Failover (TAF) feature of Oracle Net Services is a runtime failover for high-availability environments. It enables client applications to automatically reconnect to the database if the connection fails and, optionally, resume a SELECT statement that was in progress. The reconnection happens automatically from within the Oracle Call Interface (OCI) library. For applications that do insert, update or delete transactions, the application must trap the error when the failure occurs, rollback the transaction, and then resubmit. If the application is not written to be TAF aware, the session will get disconnected."
However (as I understand it) APEX runs in the database and would fail with the database, it isn't a typical "client application" connecting to Oracle via a TAF aware connection pool - it is essentially a large pl/sql package and TAF only covers SELECT statements not packages.
May be I'm over-reading this and it's simpler than that: APEX/Mod_plsql might just handle it?
- APEX User/HTTP session state is stored in database APEX: Understanding session state which is available on other nodes
- Mod_plsql in OHS can detect the error returning and reissues the request to good server and APEX on that instance can retrieve Users/HTTP state and process the request (APEX/RAC doc states mod_plsql can see an error from database and cleanup connection up and form a new connection, but not that it will retry the request for the client into other APEX/DB node).
I'm really just after a (transparent/non-transparent) statement based on experience, but an outline of how the components behave would be useful.
Thanks in advance
DaveHi
Any chance of getting that link outside of Metalink? - I'm trying to get our customer support id, but no luck at present.
I'm aware that APEX can run with RAC (as per the link I posted) - I'm really after next level info around behaviour in that environment.
Thanks

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4
Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
ManojOrcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.
