Oracle RAC multiple LISTENERS

Greetings,
I have 2 test databases on single Oracle RAC installation.
Is it possible to configure separate LISTENERS for databases?
Oracle v. 11.2.0.3
OS RHEL 6.3

Hi Farid,
Yes it is possible: You can create listener (netca or manualy) and add listener to resource srvctl .
1) Create a new RAC listener using 'netca'
As the grid user invoke "netca" from the 11.2 GRID_HOME, the select "Cluster configuration" -> "Listener configuration" -> "Add", enter Listener name as required. For example: "LISTENER_MON".
On the next page, "Select Subnet", the 2nd subnet will appear in the drop down list.
For example:
$ ./netca
Oracle Net Services Configuration:
Oracle Net Configuration Assistant is launched from Grid Infrastructure home. Network configuration will be clusterwide.
Configuring Listener:LISTENER_MON
prodserver1...
prodserver2...
Listener configuration complete.
Oracle Net Listener Startup:
Listener started successfully.
Oracle Net Services configuration successful. The exit code is 0
2) Add listener
$ ./srvctl add listener -l LISTENER_MON -s -p 1523 -k 2
3) Verify the new RAC listener
$ lsnrctl status LISTENER_MON
Thank you

Question about multiple listeners and vip addresses in rac.

We have a 2 node rac cluster running 10.2.0.3 on rhel4 on the itanium platform. We have a need where we want to connect the 2 hosts up to another network temporarily by configuring an additional network interface on each server so that we can test some connections from a different network.
My question is can you configure multiple listeners on the same server in which the newly added listener can be configured to service requets on the new network interface?
Because it's rac would you need to configure an additional vip address? I am not sure that you can have multiple vip's on a server?
Has anyone configured rac in such a way, any help is appreciated.

can you configure multiple listeners on the same server in which the newly added listener can be configured to service requets on the new network interface?Yes, you can but you should not be doing this. Listener is a node specific resource and one listener can server multiple services. You actually can create multiple services within the database for different set of users and all can be registered to the same listener.
Because it's rac would you need to configure an additional vip address? What do you mean by additional IP?
You have installed 10g RAC where you have already configured virtual IPs. Why do you want to have additional one? node1 - static ip1, vip1, pvtip1
node2 - static ip2 vip2, pvtip2
total 6
I am not sure that you can have multiple vip's on a server?Nothing to do with the server, they are based on public IP. Yes you can create multiples vip's based on same public IP. This is possible, But you do not need to do this in RAC environment.

Channel Bonding? Oracle RAC with multiple redundant network

We are planning on setting up on Oracle RAC 10g on Linux.
We have redundant switches, so I would like to set up the network to have some version of network redundancy.
Under windows, it is called 'teaming'. Linux is 'channel-bonding'
I just want to make sure if I setup the channel-bonded interfaces, it will be supported with RAC. Has anyone done this before??
-Andy

we are running our RAC on NIC bonding. Although we need to do some more testing to be real sure as to the functionality of the bond.
Metalink Note:298891.1 would be a good place to start.

Help required of creating Oracle RAC database having multiple instances

Hello Guys!
I want to create one database having 2 instances on Oracle 11g R1
I have 2 nodes in this Oracle RAC
Database name will be Val
and instance name on node 1 will be val1 and instance name on node 2 will be val2
Raw storage will be used, that is, without using automatic storage management or an Oracle Cluster File System
Can anyone help how to do that ?
Thanks

Hi,
Wonderful example thanks for the link.You're welcome :)
I'm little confused which option to choose in shared storage option of DBCA
i.e. Cluster File System or Raw devices?I suggest you to use ASM for you database storage requirement and select raw devices. oracle recommends to use ASM storage for sahred database.
thanks,

How to configure multiple listeners to listen for the same instance.

Hello everyone,
I am running oracle database 11g and I want information regarding how to configure multiple listeners to listen for the same database instance. Actually I know how to configure more than one listener but the main thing that I am confused about is when we create listener.ora file, do we have to statically register the database instance with both the listeners or the instance will register itself with both the listeners.
According to my knowledge the instance will register with the listener specified by LOCAL_LISTENER parameter and we cannot have more than one value for this parameter.
Please only give detailed answers with example as I am tired of simple answers with details that I already know.

Hello,
Yes, it can make sense to have several listener for one Oracle instance. For instance you may have one listener for the applications another listener for DBA administration tasks as well as one listener dedicated to dataguard broker. It is not possible to have several listeners listening on the same IP and Port.
By default the database try to automatically register to a listener on port 1521. To instruct the instance to register to a specifc list of listeners you can add in the init.ora the local_listener parameter with an alias definition:
i.e
local_listener=MY_SET_OFF_LISTENERS
in your tnsname.ora add an entry called:
MY_SET_OFF_LISTENERS_LOCAL= (ADDRESS_LIST=
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1530))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1531))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1532))
In this sample your instance will register to three listeners listening on respectively port 1530, 1531 and 1532
If you want your clients can be balanced over the 3 listeners

Recommendations - Oracle RAC 10g on Solaris 10 Containers Logical/Local..

Dear Oracle Experts et all
I have a couple of questions for Oracle 10g RAC implementation on Solaris and seek your advice. we are attempting to implement oracle 10g RAC on Solaris OS and SPARC Platform.
1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? I was assuming that Oracle will always link it self with OS binaries and Libraries while S/W installation and hence will need an OS image/Root Disk over which it could go. However, in containers, I assume we have a single solaris installation and configuration which will thus be shared to the containers which will be further configured in it. In such situations how does Oracle instalation proceed? Do I need to look at a scenario where, the global Container/Zone will have Oracle install and this image be shared across to zones/containers accordingly? If it is so, what all filesystems from OS will need to be shared across to these zones/containers?
Additionally, even if this approach is supported, is it a recommended approach? I am unsure about the stability and functionality of Oracle in such cases and am not able to completly conceptualize. However, I assume there could be certain items which needs to be approprietly taken care off. It will help if you could share observations from your experiences.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?
Our requirement is to have the above mentioned multiple Oracle installations spread across two (2) seperate H/W platforms,say Node A and Node B, and configure our Cluster Solution to behave as active-passive across Node A and Node B. In other words, I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. I will configure one database each for each of these Oracle S/W installation (with an idea not to have Clusterware between clustering solution VRTS/SunCluster and Oracle installation, if it works). Now I will run 3 databases thus on each of these nodes. If any downtime happens on any one of the nodes, say Node A, I will fail all oracle databases and S/W accordingly to the alternate available node, Node B in this case, using native clustering solution and I will want the database to behave as it was behaving earlier, on Node A. I am not sure though if I will be able to bring the database up on Node B when resources in OS perspective are failed over.
we want to use Oracle 10g RAC Release 2 EE on Solaris 10 OS latest/one before the latest release.
Please share your thoughts.
Regards!

1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? My understanding is that RAC in a Zone (Container) is not supported by Oracle, and will not work anyway. Regardless of installation, RAC needs to do cluster level stuff about the cluster configuration, changing network addresses dynamically, and sending guaranteed messages over the cluster interconnect. None of this stuff can be done in a Local Zone in Solaris, because Local Zones have fewer permissions that the Global Zone. This is part of the design of Solaris Zones, and nothing to do with how Oracle RAC itself works on them.
This is all down to the security model of Zones, and Local Zones lack the ability to do certain things, to stop them reconfiguring themselves and impacting other Zones. Hence RAC cannot do dynamic cluster reconfiguration in a Local Zone, such as changing virtual network addresses when a node fails.
My understanding is that RAC just cannot work in a Local Zone. This was certainly true 5 years ago (mid 2005), and was a result of the inherent design and implementation of Zones in Solaris. Things may have changed, so check the Solaris documentation, and check if Oracle RAC is supported in Local Zones. However, as I said, this limitation was inherent in the design of Zones, so I do not see how Sun could possibly have changed it so that RAC would work in a Local Zone.
To me, your only option is the Global Zone. Which pretty much destroys the argument for having Zones on a Solaris system, unless you can host other non-Oracle application on the other Zones.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?I am not sure the term 'native' is correct. All 'Cluster' software is low level, and has components that run within the operating system. Whether this is Sun Cluster, Veritas Cluster Server, or Oracle Clusterware. They are all as 'native' to Solaris as each other. They all perform the same function for Oracle RAC around Cluster management - which nodes are members of the cluster, heartbeats between nodes, reliable fast message delivery, etc.
You only need one piece of Cluster software. So pick one and use it. If you use the Sun or Veritas cluster products, then you do not need the Oracle Clusterware software. But I would use it, because it is free (included with RAC), is from Oracle themselves and so guaranteed to work, is fully supported, and is one less third party product to deal with. Having an all Oracle software stack makes things simpler and more reliable, as far as I am concerned. You can be sure that Oracle will have fully tested RAC on their own Clusterware, and be able to replicate any issues in their own support environments.
Officially the Sun and Veritas products will work and are supported. But when you get a problem with your Cluster environment, who are you going to call? You really want to avoid "finger pointing" when you have a problem, with each vendor blaming the cause of the problem on another vendor. Using an all Oracle stack is simpler, and ensures Oracle will "own" all your support problems.
Also future upgrades between versions will be simpler, as Oracle will release all their software together, and have tested it together. When using third party Cluster software, you have to wait for all vendors to release new versions of their own software, and then wait again while it is tested against all the different third party software that runs on it. I have heard of customers stuck on old versions of certain cluster products, who cannot upgrade because there are no compatible combinations in the support matrices between the cluster product and Oracle database versions.
I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. As I said before, these 3 Oracle installations will actually all be on the same Global Zone, because RAC will not go into Local Zones.

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.

Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20

Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17
Cluster 2, node 2: 192.168.17.3 / 255.255.255.0 / VLAN 17
Cluster 3, node 1: 192.168.18.2 / 255.255.255.0 / VLAN 18
Cluster 3, node 2: 192.168.18.3 / 255.255.255.0 / VLAN 18
Cluster 4, node 1: 192.168.19.2 / 255.255.255.0 / VLAN 19
Cluster 4, node 2: 192.168.19.3 / 255.255.255.0 / VLAN 19
Which eats one VLAN per RAC cluster.

Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good.

Oracle RAC on Solarais Configuration Issue

Hi,
We are trying to install Oracle RAC 10g R2 on Solaris 10.
Following are the products
1=> Soalris 10 OS
2=> Sun Cluster 3.1
3=> Veritas Volume Manager
4=> Veritas Cluster File System
Can i deploy Oracle RAC using the above listed Software.
Here we have not purchase any of the Cluster Volume Manager.
Is the CVM required to install Oracle RAC.
Is there any alternative wherein we can install Oracle RAC without using CVM like for example using the RAW device where the VM will manage storage from a single node rather than buying the CVM that will allow to manage the storage from multiple nodes.
Also i would like to highlight is suggestion for using ASM is rule out hence ASM would not be used.
Can anyone suggest me some solution to the above problem.

Well, my impression is that you don't really know what your requirements are and you are trying to fit the technologies somehow. Worse yet, there is no clear understanding how those technologies fit together and as long as you explain what your vendor is saying you (which vendor?) they don't have clear idea either.
I would also suggest to review your decision to use Sun Network Data Replicator for DR site. Consider Oracle Physical Standby database instead - it's more flexible solution and doesn't limit your choice of storage stack.
1) Do Oracle RAC 10gR2 requires any Veritas Cluster Volume Manager
Words "any" and "Veritas" contradict in your question. But the answer is no. RAC require shared storage which can generally be one of those:
- raw devices with or without some kind of cluster volume manager
- cluster file system
- NAS storage (NFS mounted)
- ASM with raw devices for CRS files (OCR and voting disks)
2) Does Oracle RAC 10g R2 require any Vertias Cluster File System or it can sit on normal Vertias File System
Again, Oracle database files MUST reside on shared storage and non-clustered file system is not an option.
3) Is there any solution where we can use the Sun Cluster with Veritas Componets to configure RAC.
If I recall correctly, Sun Cluster includes in it's license some of component of Veritas storage stack. So you might be all set. You should turn to documentation on that stage and see exactly what you have licensed and if your stack allows shared storage. You might want to have a look at http://www.sun.com/software/whitepapers/solaris10/solaris_cluster.pdf
and Oracle Certification Matrix on Metalink.

Oracle rac 11g installation

Hi
Am planning to install oracle RAC 11g on linux server. Have doubt on installation of clusterware or grid infrastructure first .?
I think grid infrastructure covers clusterware and ASM both and then oracle 11g software to be installed.
But how to download grid insfrastructure software. Will it come with oracle 11g software..? or need to download it seperately.?
Because when i try to download oracle RAC 11g which gives link to download the 11g software not grid.
Thanks in advance,

Hi,
Its called "oracle one node rac" you will find plenty of documents on metalink, extract is below, hope this helps you to understand the differences.
Oracle RAC Database : Oracle RAC database is a clustered database. It can have more than one instance running on one or more hosts. To make is database RAC , there is another software needs to be installed called Oracle Grid infrastructure which takes care of multinode sync, ASM, Oracle restart etc. Oracle GI is necessary as a base of Oracle RAC. In Oracle RAC, the load is balanced across multiple instance of databases running on different nodes. This is best for Production database. Failure of any instance is abstracted from user and forwarded to another instance from the database server pool. No of instances can be controlled using Policy Managed or Admin Managed.
Oracle RAC One Node : Some time we need to have RAC databases but donot need many instances, why? Simple answers to it is leverage the high availability of RAC. The Oracle RAC One node is a RAC DB runs on one host. The advantage is it saves your resource, can to converted to full RAC any time, Cluster fail over i.e. the Database instance is moved to new instance in case of any failure on host known as Instance Relocation,easy to upgrade etc. This type of database is well suited for small production and dev/test environments.

Oracle RAC 11g each listner correlated to a different IP

Hi expert,
a question about Oracle RAC 11g. I have 2 server RAC1 and RAC2, I must be have:
- Public interface that will be used for client communication
- Virtual IP address (VIP) that will be bind by Oracle Clusterware to the public interface
- Private interface that will be used for inter-cluster traffic. There are four major categories of inter-cluster traffic
this is my ipotetic configuration:
RAC1:
    * hostname: rac1.localdomain
    * IP Address eth0: 192.168.2.101 (public address)
    * Default Gateway eth0: 192.168.2.1 (public address)
    * IP Address eth1: 192.168.0.101 (private address)
    * Default Gateway eth1: none
RAC2:
    * hostname: rac2.localdomain
    * IP Address eth0: 192.168.2.102 (public address)
    * Default Gateway eth0: 192.168.2.1 (public address)
    * IP Address eth1: 192.168.0.102 (private address)
    * Default Gateway eth1: none
RAC1:
127.0.0.1       localhost.localdomain   localhost
# Public
192.168.2.101   rac1.localdomain        rac1
192.168.2.102   rac2.localdomain        rac2
#Private
192.168.0.101   rac1-priv.localdomain   rac1-priv
192.168.0.102   rac2-priv.localdomain   rac2-priv
#Virtual
192.168.2.111   rac1-vip.localdomain    rac1-vip
192.168.2.112   rac2-vip.localdomain    rac2-vip
#NAS
192.168.2.101   nas1.localdomain        nas1
LISTENER_RAC2 =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521)(IP = FIRST))
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.102)(PORT = 1521)(IP = FIRST))
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
LISTENER_RAC1 =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.101)(PORT = 1521)(IP = FIRST))
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)on the single server, for example, RAC1 I can configure another ethx for this VIP IP?
192.168.2.111 rac1-vip.localdomain rac1-vipor Oracle create a virtual interfaces? (for example eth0:1)
One more question. I want configure 2 listner with 2 different port, the first on 1521 and the second on 1522. Each listner correlated to a different IP
Should I configure for each server these IP?
2 VIP
2 Public
1 Private
like this, for example:
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1a-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1b-vip)(PORT = 1522)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2a-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2b-vip)(PORT = 1522)(IP = FIRST))
many thanks for all suggest,
Lain

No matter how many number of listeners that you run ... You need only 1 public ip,1 vip, 1 private ip for each node of the cluster.
All the listeners on that node use the same vip but listens only on different port numbers that you choose ...

UTL_FILE_DIR and Oracle RAC

Gentlemen,
I have installed with sucess an environment with Oracle RAC with two servers. The application that runs in these servers, has batch procedures, and it has to save flat files during these processes. When the processes run with both servers something goes wrong and the system stops. It doesn´t happen when I shutdown one of the servers. I tried to setup directories in the storage system (external disks) but it wasn´t allowed too.
Does anyone know how can I setup utl_file_dir to work with both servers? Is there another parameter to set?
Thank you all,
Best regards.

VCFS/CFS/NFS are just filesystems and UTL_FILE does file i/o. If you have sessions in multiple instances that write to the same file on a cluster filesystem, the outcome would be unpredictable. Most likely, the last person to write to the file would have their changes saved. Oracle DB (RAC or not) doesn't handle any concurrency related to UTL_FILE writes. So, even if you were in the same instance (non-RAC) and had two sessions writing to the same file, I don't think you'd get the desired results :). The file would likely be a mess and you'd have to use different file names or control concurrency yourself manually.

SQLLoader issues of Oracle RAC with ASM

One of our client wants to use Oracle RAC with ASM for our application, i just want to know if there would be any two-phased commit transactions and SQL*Loader issues in ASM.
Database is Oracle 10g

ASM works only at storage layer and has nothing to do with:
- distributed transactions
- client executable that connects to database instance: SQL*Loader, SQL*Plus, etc.
RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances but still a single database; there is no need to use distributed transactions because you have a RAC database.

BODS and Oracle RAC

Do we know of any problems with BODS and Oracle Real Application Clusters architecture? For example, a RAC TNS entry would specify one service name but multiple hosts for load balancing and failover. In BODS the connections are specified in many places (web console, datastores, job server). As far as I remember in some of those places we do have to enter the host name. Would this disqualify BODS from benefiting from RAC or would it (even worse) cause problems? Any official note by SAP on BODS and Oracle RAC?
Thanks.

Hi Mahir,
As far as I know it's only the web console that requires the hostname, however I am using DS XI 3.1 and when selecting database type Oracle in the web console there is a checkbox for 'Oracle RAC'. If you check this box then you do not require to enter the hostname.
