Doubt on RAC IP configurations

Dear Legends,
As I'm trying to install RAC in VMWARE with OEL 5.7 64 bit and 11gR2 by following the article "ORACLE-BASE - Oracle Database 11g Release 2 RAC On Linux Using VMware Server 2"
Our Public host name "verac1.host.net" and "verac2.host.net"
VM Settings is "BRIDGED"
#PUBLIC
192.168.1.180 verac1.host.net verac1 -->
192.168.1.181 verac2.host.net verac2
#PRIVATE
192.168.0.10 verac1.host.net verac1-priv
192.168.0.11 verac2.host.net verac2-priv
#Virtual
192.168.1.182 verac1-vip.host.net verac1-vip
192.168.1.183 verac2-vip.host.net verac2-vip
May I know these are the right one am using or not?
While trying to nslookup public hostname it is working from both nodes, but
nslookup verac1-priv
nslookup verac2-priv
nslookup verac1-vip
nslookup verac2-vip
error as : ** server can't find verac1-priv: NXDOMAIN
Do I need to proceed ? Or I need to rectify it here.
My Ip details
Router: 192.168.1.10
Thanks,
Karthik

Hi,
Some what after trying out with the Doc ID's and references provided I tried to configure DNS in RAC1 and RAC2. Now my IP configurations as follows..
cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
#PUBLIC
192.168.1.180 verac1.host.net      verac1
192.168.1.181 verac2.host.net      verac2
#PRIVATE
10.10.2.10      verac1-priv.host.net      verac1-priv
10.10.2.15      verac2-priv.host.net      verac2-priv
#VIP
10.10.1.10      verac1-vip.host.net       verac1-vip
10.10.1.15      verac2-vip.host.net       verac2-vip
Now the following works
1. nslookup verac1, verac2
[root@verac1 ~]# nslookup verac2
Server:         192.168.1.180
Address:        192.168.1.180#53
Name:   verac2.host.net
Address: 192.168.1.181
[root@verac2 ~]# nslookup verac1
Server:         192.168.1.181
Address:        192.168.1.181#53
Name:   verac1.host.net
Address: 192.168.1.180
2. nslookup verac1-vip, verac2-vip
[root@verac1 ~]# nslookup verac2-vip
Server:         192.168.1.180
Address:        192.168.1.180#53
Name:   verac2-vip.host.net
Address: 10.10.1.20
[root@verac2 ~]# nslookup verac1-vip
Server:         192.168.1.181
Address:        192.168.1.181#53
Name:   verac1-vip.host.net
Address: 10.10.1.10
3. SCAN
[root@verac1 ~]# nslookup verac-scan
Server:         192.168.1.180
Address:        192.168.1.180#53
Name:   verac-scan.host.net
Address: 10.10.1.11
Name:   verac-scan.host.net
Address: 10.10.1.12
[root@verac1 ~]# nslookup verac-scan
Server:         192.168.1.180
Address:        192.168.1.180#53
Name:   verac-scan.host.net
Address: 10.10.1.12
Name:   verac-scan.host.net
Address: 10.10.1.11
But the Following is NOT Working
1. nslookup verac1-priv, verac2-priv
[root@verac1 ~]# nslookup verac2-priv
;; connection timed out; no servers could be reached
[root@verac2 ~]# nslookup verac1-priv
;; connection timed out; no servers could be reached
2. Google or Out side World Ping is NOT Working
[root@verac1 ~]# ping google.com
ping: unknown host google.com
If I disable eth1 and eth2, then google ping is working... Not Sure how to configure the DNS

Oracle RAC IP Configuration

Hi all
How Oracle RAC IP configuration uses gateway.
Thanks in advance,
Sarathi

Hi Friend,
Thumb Rules :
1. All public NICs must have the same name on all nodes in the cluster
2. Similarly, all private NICs must also have the same names on all nodes
Use component verifications commands like 'nodereach' or 'nodecon' for this purpose. Type cluvfy comp -help on the command prompt. If the 'cluvfy comp nodecon' command is invoked without -i, cluvfy will attempt to discover all the available interfaces and the corresponding IP address & subnet. Then cluvfy will try to verify the node connectivity per subnet.
You can run this command in verbose mode to find out the mappings between the interfaces, IP addresses and subnets. You can check the connectivity among the nodes by specifying the interface name(s) through -i argument

Doubt in Benefits Module configuration..please clrify

Hi Friends,
I am having doubt in configuration steps in Benefits module.Here i have configured
Benefit Area,Assigned currency to Benefit Area,Defined Benefit providers,Set current Benefit Area,Defined Benefit plan types,Status,Defined Employee criteria groupings(parameter groupings,salary groups,age groups,Seniority groups),Defined cost groupings,Defined coverage groupings.
In Health plans i defined Health plan genral data,options for health plans,dependent coverage options,Defined Cost Variants,Defined cost rules.
I struck up from this point onwards.My qurries are
1.Is it compulsary to Assign Health plan attributes!
2.What are follwing steps of configuration after Assign Health Plan attributes!

Hi Vikram,
1. yes you should assign Assign Health plan attributes; without assigning this u can' process the further steps this is the integration point off your plan options with cost rules
2. after the above step the following are the mandatory steps to follo:
a. Flexible administration --- define administrative parameters (Mandatory)
b. Prerequisite and Corequisite plans (Optional--based on ur client needs)
c. Adjustment reasons (Optional-if u have any adjustments it is mandatory)
d. Programs ; 1st program Grouping and Second program groupin( Mandatory without assigning this you can't process)
e. Define Benefit Programs (mandatory)
f. Employee Eligibility : eligibility grouping and variant and eligibility rules ( Mandatory)
g. Standard Selections: Health plans (Mandatory)
after config all those steps then you go to T-Code HRBEN0001 there you can enrol youa employees .

10G RAC Database Configuration Querry??

Hi All,
I have installed the 10GR3 Grid and deployed the Agent to a system which has 10GR2 RAC Database with CRS installed.
1) When i try to configure the cluster database, should we use the VIP TNS entries as the Connect string or the Physical Node TNS Address.
2) After i have configured it i do not see Listener shown for either monitoring nor i am able to add manually.
3) Will any CRS components be monitored through Grid? For Me i dont find any though the CRS HOME oratab entry is enabled.
Please share your ideas and experience.. on this..

Is RAC node configuration when disk array fails on one node .

Hi ,
We recently had all the filesystem of node 1 of RAC cluster , turned into read only mode. Upon further investigation it was revealed that it was due to disks array failure on node 1 . The database instance on node 2 is up and running fine . The OS team are rebuilding the node 1 from scratch and will restore oracle installable from the backup .
My question is once all files are restored :
Do we need to add the node to the RAC configuration ?
Do we need to do relink of oracle binary files ?
Can the node be brought up directly once all the oracle installables are restored properly or will the oRacle team require to perform addition steps to bring the node into RAC configuration .Thanks,
Sachin K

Hi ,
If the restore fails in some way . We will require to first remove and then add the nodes to the node 1 cluster right ? Kindly confirm on the below steps.
In case of such situation below are the steps we plan to follow:
version ; 10.2.0.5
Affected node :prd_node1
Affected instance :PRDB1
Surviving Node :prd_node2
Surviving instance: PRDB2
DB Listener on prd_node1:LISTENER_PRD01
ASM listener on prd_node1:LISTENER_PRDASM01
DB Listener on prd_node2:LISTENER_PRD02
ASM listener on prd_node2:LISTENER_PRDASM02
Login to the surviving node .In our case its prd_node2
Step 1 - Remove ONS information :
Execute as root the following command to find out the remote port number to be used
$cat $CRS_HOME/opmn/conf/ons.config
and remove the information pertaining the node to be deleted using
#$CRS_HOME/bin/racgons remove_config prd_node1:6200
Step 2 - Remove resources :
In this step, the resources that were defined on this node has to be removed. These resources include (a) Database (b) Instance (c) ASM. A list of this can
be acquired by running crs_stat -t command from any node
The srvctl remove listener command used below is only applicable in 10204 and higher releases including 11.1.0.6. The command will report an error if the
clusterware version is less than 10204. If clusterware version is less than 10204, use netca to remove the listener
srvctl remove listener -n prd_node1 -l LISTENER_PRD01
srvctl remove listener -n prd_node1 -l LISTENER_PRDASM01
srvctl remove instance -d PRDB -i PRDB1
srvctl remove asm -n prd_node1 -i +ASM1
Step 3 Execute rootdeletenode.sh :
From the node that you are not deleting execute as root the following command which will help find out the node number of the node that you want to delete
#$CRS_HOME/bin/olsnodes -n
this number can be passed to the rootdeletenode.sh command which is to be executed as root from any node which is going to remain in the cluster.
#$CRS_HOME/install/rootdeletenode.sh prd_node1,1
Step 5 Update the Inventory :
From the node which is going to remain in the cluster run the following command as owner of the CRS_HOME. The argument to be passed to the CLUSTER_NODES is a
comma seperated list of node names of the cluster which are going to remain in the cluster. This step needs to be performed from once per home (Clusterware,
ASM and RDBMS homes).
## Example of running runInstaller to update inventory in Clusterware home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORA_CRS_HOME "CLUSTER_NODES=prd_node2" CRS=TRUE
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in ASM home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ASM_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in RDBMS home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
We need steps to add the node back into the cluster . Can anyone please help us on this ?
Thanks,
Sachin K

Doubt on first time configuration

good eve everyone,
sir this is the first time i installed times ten on windows 7.after installing i done config by going to administrative tools->ODBC then i created the imdb name and the database character set as same as my oracle set and under first connection tab i configured permanent data size as 40 ,temporary data size as 32,replication parallelism buffer MB as 64 and under IMDB cache tab i named the oracle net service as orcl_db then i went to ttisql then this follows

This forum is not really the vehicle to provide detailed tutorials. To understand how to get started with TimesTen you need to invest a little time to (a) read some of the documentation and (b) follow the various 'how to' tutorials included in the TimesTen QuickStart. The documentation and the QuickStart are installed automatically when you install TimesTen on Windows.

RAC setup- Configure hostname in ODI agent

I have my Master & Work repositories hosted on a Oracle RAC environment. I have a standalone ODI agent which might installed in the same physical server or in a different server.
In a RAC setup, there are multiple hostnames for the same database. How do I make the ODI agent aware that it should look into a 2nd server (when the 1st host is down) when trying to connect to the repository ? I want to know where this should be configured in the agent setup.
Does this get automatically taken care of once I include both the hostnames in the JDBC URL of the repositories ?

All depends on the JDBC you're using...
JDBC Thin work with the Oracle listener,
and JDBC OCI (which need an Oracle Client on the machine) works with a TNS description (here you can define several HOST).
I had have several issues with the Thin on our RAC so we've changed for an OCI one...

Brice

Question on 11.2 RAC Networking Configuration

I have a random question regarding the network interface configuration for (specifically 11.2) an Oracle RAC requirement. Is there a requirement anywhere that states that all nodes in the cluster must have the same named interface on each distinct node serving the same purpose in order for all nodes of the cluster to communicate properly?
Here is an example of my question - My curiosity is, is this a requirement?
Node 1
eth1 - 10.0.0.1 (public)
eth1:1 10.0.0.25 (vip)
eth2: 192.168.1.25 (priv/interconnect)
Node 2
eth1 10.0.0.2 (public)
eth1:2 10.0.0.26 (vip)
eth5: 192.168.1.35 (priv/interconnect)
Note: eth2 is private on node 1, where eth5 is private on node 2.
Does node 2 have to follow the same pattern where eth1 is public, and eth2 is private, or for node 2, can eth5 be assigned to the private subnet and eth1 be assigned to the public subnet?
Odd question I know. Any means to clarify for me would be most helpful and appreciated.
Thanks,
CJ

Doc 11.2.0.2 says:
About Network Hardware Requirements
* Public interface names must be the same for all nodes. If the public interface on one node uses the network adapter eth0, then you must configure eth0 as the public interface on all nodes. Network interface names are case-sensitive.
* You should configure the same private interface names for all nodes as well. If eth1 is the private interface name for the first node, then eth1 should be the private interface name for your second node. Network interface names are case-sensitive.
http://download.oracle.com/docs/cd/E11882_01/rac.112/e17264/preparing.htm#TDPRC123
Network Hardware Requirements (Linux Installation)
If you install Oracle Clusterware using OUI, then the public interface names associated with the network adapters for each network must be the same on all nodes, and the private interface names associated with the network adaptors should be the same on all nodes. This restriction does not apply if you use cloning, either to create a new cluster, or to add nodes to an existing cluster.
For example: With a two-node cluster, you cannot configure network adapters on node1 with eth0 as the public interface, but on node2 have eth1 as the public interface. Public interface names must be the same, so you must configure eth0 as public on both nodes. You should configure the private interfaces on the same network adapters as well. If eth1 is the private interface for node1, then eth1 should be the private interface for node2.
http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/prelinux.htm#CWLIN209
As the documentation says this restriction is valid when Install using the OUI, but have different interface name is supported if configured manually.
Anyway if you are installing using the OUI you have the option to rename the interface thus like Bjoern said.

Redolog doubt in RAC

Hi,
I have small doubt regarding redolog corruption/deletion in RAC Instance:
OS: RHEL 4.5
Oracle: 10.2.0.1
DB_NAME=RAC ( 2 Instances, RAC1 and RAC2 are pointed to this DB).
One user (User1) is connected to DB using RAC1 Instance having redolog groups 2 (having each one member: redo1a.log and redo2a.log). I did logswitch freshly and Presently current redolog is redo2a.log. User1 created emp table and inserted 20 records and commited. note that, still current redolog is redo2a.log and there is no log switch. There are no users connected to DB other than user1.
Now, I shutdown abort the RAC1 instance and User1 session is switched to RAC2 Instance. When he queries the select * from emp table, he is getting 20 records? how come he gets? the inserted records are still in redolog2a.log of RAC1 instance and commit statement is also still there in redolog and thre is no log switch, instance RAC1 is shutdown abruptly. How come he gets 20 records, when he connected to RAC2 instance?
Please explain me, how it is possible? please execuse me, if there is anything wrong with my question.

Whether it is RAC or non RAC system DBWn process writes the dirty buffers to disk.
The DBWn process writes dirty buffer to disk under the following conditions:
1. When a checkpoint is issued.
2. When a server process cannot find a clean reusable buffer after scanning a threshold number of buffers.
3. Every 3 seconds
if still not written to disk when you start database next time media recovery will be completed.
Where in RAC environment it works on concept of GLOBAL CACHE. Whichever changes happening to 1st node same will be update to 2nd node as well. when node 1 goes down abruptly 2nd node identifies it and does the media recovery. so even when user again connects to 2nd node still data will be available.

DOUBT|comprehensive model | gateway configuration | CVP VXMLServer

Hi all,
Am setting up a comprehesive mode
call flow is like that call from ACD will come through ivr through E1 and calls will be forwrded to cvp servers by static route and bootstarp serveices is invoke for icm label creation configured in gateway.Now my doubt is,how to make some 3 to 4 servers to handle calls simultaneoulsy without preference model wihout proxy servers .As of now am working with one CVP server>need to add few more
is there any configuartion required to do this
ACD------> gaetway------>CVP servers----->ICM-------->IVR will play
Thanks
Bala

Hello Bala,
The only other way i can think of is sending the call to the DNS Server where it can resolve to multiple IP address using a DNS SRV file. Below is the section from CVP SRND which explains your scenario.
"When a call arrives at an Ingress Gateway, the dial peer can use DNS to alternate calls between the
two SIP Proxy Servers. The SIP Proxy Servers can also use DNS to distribute incoming calls among
multiple SIP Services. If SIP Proxy Servers are not being used, then the Ingress Gateway can use
DNS directly to distribute inbound calls among multiple SIP Services"
You can achieve this using the dial-peer Session Target.
dial-peer voice 75795 voip
session target dns:cvp.callserver.com
Have a look at the below blog which explains the SIP Proxy Reduncancy, but it can also be done for CVP

Doubts about RAC infraestructure with one disk array

Hello everybody,
I'm writing to you because we have a doubt about the correct infrastructure to implement RAC.
Please, let me first explain the current design we are using for Oracle DB storage. Currently we are running several standalone instances in several servers, all of them connected to a SAN disk storage array. As we know this is a single point of failure we have redundant controlfiles, archiveds and redos both in the array and in the internal disk of each server, so in case array completely fails we “just” need to recover nightly cold backup, apply archs and redos and everything it's ok. This can be done because we have standalone instances and we can assume this 1 hour downtime.
Now we want to use these servers and this array to implement a RAC solution and we know this array is our single point of failure and wonder if it's possible to have a multinode RAC solution (not RAC One Node) with redundant controlfiles/archs/redos in internal disks. Is it possible to have each node writing full RAC controlfiles/archs/redos in internal disks and apply these files consistently when the ASM filesystem used for RAC is restores (i.e. with a softlink in an internal disk and using just one node)? Or maybe the recommended solution is to have a second array to avoid this single point of failure?
Thanks a lot!

cssl wrote:
Or maybe the recommended solution is to have a second array to avoid this single point of failure?Correct. This is the proper solution.
In this case you can also decide to simply use striping on both arrays, then mirror array1's data onto array2 using ASM redundancy options.
Also keep in mind that redundancy is also need for the connectivity. So you need at least 2 switches to connect to both arrays, and dual HBA ports on each server, with 2 fibres running, one to each switch. You will need multipath driver s/w on the server to deal with the multiple I/O paths to the same storage LUNs.
Likewise you need to repeat this for your Interconnect. 2 private switches, 2 private NICs on each server that are bonded. Then connect these 2 NICs to the 2 switches, one NIC per switch.
Also do not forget spares. Spare switches (one each for storage and Interconnect). Spare cables - fibre and whatever is used for the Interconnect.
Bottom line - not a cheap solution to have full redundancy. What can be done is to combine the storage connection/protocol layer with the Interconnect layer and run both over the same architecture. Oracle's Database Machine and Exadata Storage Servers do this. You can run your storage protocol (e.g. SRP) and your Interconnect protocol (TCP or RDS) over the same 40Gb Infiniband infrastructure.
Thus only 2 Infiniband switches are needed for redundancy, plus 1 spare. With each server running a dual port HCA and a cable to each of these 2 switches.

Doubt in Integration Scenario Configurator- Not able to assing sender chane

Hi All,
i have imported the integration scenario to the Directory.
Assigned the relevant business services to both Sender and Receiver.
I am able to assign a Receiver Communication Channel.
But for sender system communication system , it shows 'Not Required'. i am not able to do anything. Sender is a Third Party System. I have created a sender JMS channel under it.
could someone suggest what is to be done?

If you configured your sender BS and CC correctly it must show..
one try go and create a dummy sender agrement for the same interface check it is allowing there ,,if yes then u doing something wrong in configuaration scenarion.
