MSCS on two nodes

Hi Guru's
I have to install SAP ECC 6.0 on MS Windows 2003 for production server.
I have 2 different servers and they are going to be under Microsoft Cluster.
Requirement is I have to install Central instance on one server (Node A) and
Database server on another server (Node B), this cluster will be active-active mode.
kindly give me solution - how to install this and configure the cluster for the same
and also the detailed steps.
Thanks in advance.
Abdul Jabbar.

Hi Abdul Jabar,
MS Cluster does not support to Active+ Active Configuration, MS Cluster basically using for the Failover between two servers, which we called the Active+Passive Configuration.
IP requirements
Heartbeat= 1 private IP requied
Public Lan= 2 PUBLIC lan IPs for both Node
Cluster IP= 4 Clusters IPS
1) Clustering the SQL server database Software from Node A, it will auto install on Both Nodes
2) Clustering the SQL SP1 from Node A, It will auto install on Both Nodes.
3) Install the Central Service Instance for ABAP (ASCS) on SHARED (S:\kernel)
4) Install the Central Service Instance for JAVA (SCS) on SHARED (S:\kernel)
5) Configuring the First MSCS Node from Node A
6) Installing the DB Instance on Shared (F:\; L:\) from Node A
7) Configuring the Additional Cluster Node from Node B: on Shared disk
8) Installing the Enqueue Replication Server on Local Disk
You have to perform the installation at least four times, for each A(SCS) instance on both MSCS Node
9) Installing the CI on local disk on Node A
10) Installing the DI on local disk on Node B

How to create reports servers with the same name in two nodes in Reports

Greetings
We are migrating Oracle Application Server 10g (9.0.4) to a better hardware infrastructure with high availability. We want to provide 2 new Oracle Application Server 10g (9.0.4) in High availability and we want to avoid modify the existing forms and reports code, but the code is looking for a specific reports server name when calling reports, but I couldn't create the same reports server name in the both oas machines, I could create the reports server in only one node. I want to create a reports server with the same name in both nodes but it is not possible. I know that there is a procedure to do that in 10.1,2 (Note 437228.1, How to Create Two Reports Servers With the Same Name in the Same Subnet) but I couldn't find the equivalent procedure in 9.0.4.
Anybody kwows how to create a reports server with the same name in two nodes using 10g (9.0.4)
Thanks
Ramiro Ortiz.

Hello.
I applied the patch 4092150 on my oas 9.0.4.2 and I modified my rwnetwork.conf file changing the port to 14022 by following the note "How to Create Two Reports Servers With the Same Name in the Same Subnet? [ID 437228.1]" but I am facing the same error rep-56040 "server already exists in the network".
When I run osfind command I get the following information (My reports server is senarep and I want to create it on SNMMBOGOAS10):

Can fiber channel be used for connect server to a storage in two nodes RAC

I decided to have an Oracle RAC cluster with only two nodes.
The storage I have is a sun 3510FC. Also have five fiber chanal ports. But my each server (Sunfire v240) has got one Ultra160SCSI multimode (SE/LVD) not any fiber chanal ports. I found that there is some FC card available to use but none fiber switch available. I want to install this FC cards to the servers and make a straight connection with fibre cable to the storage. Can this be asolution or do i have to have a fibre switch?

Hi
Irrespective of whether such a configuration is supported or not by Oracle.
Has anybody got 10gR2 RAC working on
a. 2 servers
b. shared storage with HBA and fibre channel cables
c. interconnect on LAN
(yes we know it is not supported by Oracle...but again we are not going production on that....just for demo/training purposes)
No FC switch
No ethernet switch
If anybody has got this working would be great to hear of 'issues to guard against'
Thanks

Configure OEM in Oracle 10.2.0.4 Two nodes RAC

Hi all,
I'm having some troubles making rigth configuration for OEM in my RAC.
Everything during installation or configuracion seems ok but later it's all wrong.
The point is:
Global database is ON and every of two nodes is also ON. I can accees it from inside and outside the server nodes.
CRS shows everything OK with all services and resources ONLINE.
emctl status dbconsole -clusterhttps://node2:5500/em/console/aboutApplication
EM Daemon is running.
emca -displayConfig dbcontrol -clusterINFO:
**************** Current Configurationl ****************
INSTANCE NODE DBCONTROL_UPLOAD_HOST
inode2 node2 node2
inode1 node1 node2
So everything should be OK
When I try to access OEM, it says that status can't be acess and offers me the choice of START or BEGIN RECOVER
When I go through START the two nodes are up but can't access the instances.
So I know that something has wrong configuracion but I don't know WHAT!!!
Any Idea???
Thanks in advance

Start looking at the logs under $OH/<node_name>/sysman/log - most likely it will offer some clues.

How to draw a line on ADF page between two nodes for mapping.

Hi everyone,
Does anyone have a solution that how can I wiring two points by drawing a line on ADF pages.
My scenario is user want to do a mapping between two xml files. We will build an ADF faces page. This page have two parts, left part contains one tree(base on the source xml), right part is the destination tree(target xml). User can drag an node from left and drop to right. Meantime, a line will be created to connect two node, it would be perfect that when user scroll down the page, or extend the tree node, the line between source and target will be remain connection two node.
Does anyone have a solution for this, thanks in advance.

11gR2- webutil upload file to AS on two nodes RAC?

Hellow experts plz help with the following issue,
we are using 11gR2 forms on two node rac,webutil configured on both nodes. upload/download files to AS folder(UP_FILES) using our forms. node 2 is actually replica of node 1(forms,reports,UP_FILES). we are now facing a problem that the form which upload file to AS, only upload that to the node from where it is running say if it is running from node1 then it upload files to folder UP_FILES on that node( as the entry in webutil.cfg file) but we want that UP_FILES folder should be synced with each other on both nodes and a form running whether from node1 or node2 upload the file to both nodes at time.
How this will be accomplished?
--------webutil.cfg entry
transfer.appsrv.read.3=D:\UP_FILES
transfer.appsrv.write.3=D:\UP_FILES
-----FORM UPLOAD CODE
      IF :CONTROL.FILE_LOC IS NOT NULL THEN
        acyr3 := :CONTROL.TXTVOUCHERNO||'-'||acyr2 ;
       FILE_RESULT := WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS_WITH_PROGRESS(CLIENTFILE=>:CONTROL.FILE_LOC,
       SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'UPLOAD TO DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT' );
      END IF;
--FORM DOWNLOAD CODE
        FILE_RESULT := WEBUTIL_FILE_TRANSFER.AS_TO_CLIENT_WITH_PROGRESS
             CLIENTFILE=>'D:\UP_FILES\'||acyr3||'.PDF',
        SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'DOWNLOAD FROM DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT'
             CLIENT_HOST('rundll32.exe url.dll,FileProtocolHandler D:\UP_FILES\'||acyr3||'.PDF');
             IF FILE_RESULT THEN
message('File downloaded successfully from the Application Server');
END IF;

Well, you're uploading the file to one node, so this is no surprise. What you can do is to store your file on a shared folder (which might be a bit tricky on windows) or synchronize a folder between your nodes. Unfortunately Forms can't access ASM directly (assuming you are using ASM), so you can't store your files directly in ASM where it would be accessible from both nodes.
cheers

2. I have installed a second single instance db on node 2 (Oracle Sid = test-2) with NTFS file system for datafiles
3. Database is up and running, but I am not able to connect it from any client.
4. I am getting ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
5. Database (test2) is registered with grid LISTENER
5. TNSPING from client machine response is ok
Am I missing something here, happy to provide more info if requested.

2012 R2 Hyper-V Cluster two node design with abundance 1Gbps NICs and FC storage

Hello All,
First post so please be gentle!
We are currently in the process of building/testing the upgrade of two node 2012 R2 Hyper-V cluster.
Two hosts built with Datacentre 2012 R2 which will host approx. 30 VM's.
Shared storage will be fault tolerant FC- connection.
10, (yes 10!) 1Gbps NICs are available, Intel i350.
trying to decide on teaming interfaces using native LBFO and the 2008 'style' of using un-converged networking, or teaming up most interfaces and using QoS. Can find many/numerous examples of using 10Gbps NICs and converged, however 10Gbps networking
isn't an option right now.
recommendations appreciated.
thanks

Hi Sir,
>>trying to decide on teaming interfaces using native LBFO and the 2008 'style' of using un-converged networking, or teaming up most interfaces and using QoS.
The following link detailed the teaming configuration and it's applicable scenario (server 2012):
http://www.aidanfinn.com/?p=14039
Also please refer to the document for 2012R2 LBFO :
http://www.microsoft.com/en-us/download/details.aspx?id=40319
In server 2012R2 , there is a new setting "Dynamic" for "load banacing mode " and it is recommended to use Dynamic for "Load banacing mode" :
If you can accept 1GB max bandwidth for each VM I would suggest you to use LBFO mode : Independent/dynamic/None(All adapter active) .

Testing ha-nfs in two node cluster (cannot statvfs /global/nfs: I/O error )

Hi all,
I am testing HA-NFS(Failover) on two node cluster. I have sun fire v240 ,e250 and Netra st a1000/d1000 storage. I have installed Solaris 10 update 6 and cluster packages on both nodes.
I have created one global file system (/dev/did/dsk/d4s7) and mounted as /global/nfs. This file system is accessible form both the nodes. I have configured ha-nfs according to the document, Sun Cluster Data Service for NFS Guide for Solaris, using command line interface.
Logical host is pinging from nfs client. I have mounted there using logical hostname. For testing purpose I have made one machine down. After this step files tem is giving I/O error (server and client). And when I run df command it is showing
df: cannot statvfs /global/nfs: I/O error.
I have configured with following commands.
#clnode status
# mkdir -p /global/nfs
# clresourcegroup create -n test1,test2 -p Pathprefix=/global/nfs rg-nfs
I have added logical hostname,ip address in /etc/hosts
I have commented hosts and rpc lines in /etc/nsswitch.conf
# clreslogicalhostname create -g rg-nfs -h ha-host-1 -N
sc_ipmp0@test1, sc_ipmp0@test2 ha-host-1
# mkdir /global/nfs/SUNW.nfs
Created one file called dfstab.user-home in /global/nfs/SUNW.nfs and that file contains follwing line
share -F nfs –o rw /global/nfs
# clresourcetype register SUNW.nfs
# clresource create -g rg-nfs -t SUNW.nfs ; user-home
# clresourcegroup online -M rg-nfs
Where I went wrong? Can any one provide document on this?
Any help..?
Thanks in advance.

Creation of diskset in Two node cluster

Hi All ,
I have created one diskset in solaris 9 using SVM in two node cluster.
After diskset creation, I mounted the diskset in a primary node in the mount point /test. But, the disk set is mounting on both the nodes.
I created this diskset for failover purposes, if one node goes down the other node will take care.
My idea is to create a failover resource (diskset resources) in the two node cluster.
Below are steps used for creating the disk set.
root@host2# /usr/cluster/bin/scdidadm -L d8
8        host1:/dev/rdsk/c1t9d0   /dev/did/rdsk/d8
8        host2:/dev/rdsk/c1t9d0   /dev/did/rdsk/d8

metaset -s diskset -a -m host2 host1

metainit -s diskset d40 1 1 /dev/did/dsk/d8s0
newfs /dev/md/diskset/rdsk/d40
mount /dev/md/diskset/dsk/d40 /test
root@host2# metaset -s diskset

host2                  Yes
host1
Mediator Host(s)    Aliases
host2
host1
Driv Dbase
d8   YesPlease let me know how to mount the disk set in one node.
If i am wrong, please correct me.
Regards,
R. Rajesh Kannan.

The file system will only mount on both (all) nodes if you mount it globally, i.e with the global flag or if there is an entry in /etc/vfstab that has a global option.
Given your output below, I would guess you have a global mount for /test defined in /etc/vfstab.

Tim

11g r2 non rac using asm for sun cluster os (two node but non-rac)

How to create candidate disk in solaris cluster (sparc os) to install grid home in asm.. please provide me the steps if anyone knows

Please refer the thread Re: 11GR2 ASM in non-rac node not starting... failing with error ORA-29701

Oracle 11gR2 RAC setup with ASM option running on two nodes . Seeking help

Hi ,
Recently we have migrated to 11gR2 extended RAC for one of our application using ASM . Its a two node RAC setup . We are using ASM Normal redundancy feature maintaining two failure group .
I need few clarification regarding our new DR set up .
We are planning to have EMC SRDF replication from any of node storage ( Either 1 or 2) to the DR disks .
Its stright to use when we use the normal file systems . In case of ASM , I am not sure how this replication will work ? and on which level the replication should happen ?
Do i need an ASM instance up and running on DR server , Which will recognize the disks as it is once DR disks are separated from prod replication and assigned to the server ?
What should be prerequisite on DR server before we can start the srdf replication (EMC) and make it work .
Thanks for All your Valuble suggestion .

Before you decide to use EMC replication give considerable thought to the fact that you are introducing a single point of failure.
Hardware snapshot replication is very fast. That is all it is. If you database crashes because of corruption on disk ... your replica will be equally corrupt.
What is fast can not do what DataGuard does ... verify quality. If the point is DR. Go with DataGuard unless EMC is willing to, in writing (not verbally) give you a guarantee (in hard cash) to cover all costs if they replicate bad blocks and it causes an outage.
And just so no one thinks I'm picking o EMC ... the same weakness exists with all of the other storage vendor's products.

Load Balance Problem in Oracle RAC 10.2.0.4 (two nodes with CRS)

Hi all,
I have an Oracle RAC 10.2.0.4 with two nodes and I'm having problems with sessions load balance.
The problem is that all connections are going to the node which is enabled as 'master' in RAC, the node who has located .db resource in CRS.
If .db resource is located in node1 all connections are made in node1. In the same way, all connections are made in node2 when .db resource from CRS stack is located in node2.
The connections are made by a pool in Tomcat 6 using RAC service for made the connections.
Any idea?
Thanks in advance.
Here is an example of my net configuration:
listener.ora in node1:
LISTENER_RAC_NODE1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1525)(IP = FIRST))
tnsnames in node1:
LISTENERS_RAC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2_vip)(PORT = 1525))
NODE1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rac)
(INSTANCE_NAME = rac1)
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2_vip)(PORT = 1525))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rac)

It is my fault.
It was the connection service. I had one one with preferred option and one without it. Now is working well.

Updating a table from two nodes simultaneously using sqlloader- Issues..

Hi,
I have a two node RAC. I have a table called PARTS1, has an PK+Index on PART column, Again this has a sequence. Now I am loading data on PARTS1 table using sqlloader from both nodes at the same time. What issues will come?
Since one column of this table has a PK+Sequence+Index, there will be a contention issue with the block while updating records.. am I right? What other isues might appear here?
Thanks in advance,
Lily.

Consider two databases
db10gA and db10gB which is having a db link from A to B
There is a user A in db10gA
and another user B in db10gB
the user require to insert,update,delete records of user B tables
so how is the DML privileges are granted to user A to perform these tasks at db10gB database
whether it is the type of db link decides to do these tasks
whether any synonym created at db10gA side might help to do the jobUser A will act on behalf of the user who has created the DBLINK; for example if you have created the DBLINK with a user having a DBA role; and grant the DBLINK access to A, A can act on behalf of the DBA who has created the DBLINK.
