Simple "cluster" setup

I am reviewing the requirements to setup a centralized management environment and was looking for some guidance on two things so far....
1. If I have a standalone c360 running right now processing mail and I create a new cluster, I realize it will use the standalone settings as the cluster level
settings as it is the first box in the cluster, but will it require me to restart the appliance before I can join a second box to the cluster?
2. At this point if I only have two devices in a single datacenter, is it mandatory or a best practice for me to both the cluster level and the group level?
Thanks,
Chris

Chris,
For the first question, You do not need to restart any of the appliances.
For the second one, with only two appliances in the setup, I would recommend using cluster level settings only. The group will be helpful if you require to have multiple sets of appliances with different configuration for each set.
Hope this will be helpful.

OSB cluster setup with SSL

Hi,
Could any one help me here..

Verify HA Cluster setup in Oracle Virtual machine thru GUI

Hi All,
I have setup 3 node cluster with HA[Oracle VM] enabled.When i checked in the GUI it
shows "High availability Infrastructure works well" like that.
For testing HA, I poweroff one of the Oracle Virtual server node from the Oracle Virtual manager browser.
Then if i checked the "Server Pools > Edit Server Pool ".check for "High Availability Infrastructure" browser keep going.
Also one more thing is the Powered off machine automatically after some time it is coming up.Is
it right ?
After powered off if i run the below command in ovmmgr it shows 2 nodes are up.Same o/p
how can i get in GUI when i clicked High Availability Infrastructure in "Server Pools > Edit Server Pool "
[root@xxxovmsr1 ~]# /usr/lib/ovs/ovs-cluster-check master alter-fstab
O2CB cluster ocfs2 already online
2
Cluster setup complete.
Link hangs quit sometime.Not allowing new connections also ..What to do ?
Basic question
How to verify the cluster setup from the GUI when i click "High Availability Infrastructure" check button?
Some one can help me in this please ?
Regards,
JK

Hey,
After powered off one of VM server if i run the below command in ovmmgr it shows 2 nodes are up.
Why are you going ovmmgr ?
Are your checking it only thru gui part of the manager or also thru thr command line.
Oracle vm server - are hosts for your virtual systems your create on them.
If you power off the server - from GUI part you can see - it as switched off or unreachable
If your HA feature is enabled for that pool having more than 1 server sharing the /OVS filesystem - then he virtual system which is runnign on 1 of the Oracle VM server - will not die
It will migrate to other available server in the pool - which is whole idea and purpose of HA
I don't understand what exactly you are trying to crosscheck or verify here with these commands
High Availability Infrastructure in "Server Pools > Edit Server Pool "
root@xxxoxxxr1 ~# /usr/lib/ovs/ovs-cluster-check master alter-fstab
O2CB cluster ocfs2 already online
2
Cluster setup complete.
If you have to check whether your HA feature is working - form GUI you can got o server pool - tab -
edit it
and chk the HA - tab
and verify-
it HA feature is working properly - it will give you message accordingly.

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.

BAM Cluster setup - issue with whole server migration configuration

HI,
We are working on a SOA , BAM , BPM Cluster setup on OEL VMs
With Admin server running on Host1 and Soa_server1, BAM_server1 , Host2 - Soa_server2 , Bam_server2.
We were successfully able to setup clustering for Soa without using the webTier utilities in our environment, Just by adding entries in the /etc/hosts file.
Followed the document - except for web tier setup
http://www.namredlek.nl/orasoa/InstallSOASuite11gOnCluster_v1.pdf
1)     Installed Weblogic 11g.
2)     Soa 11g.
3)     Domain creation
4) Configured Node manager
5) Soa Clustering completed successfully.
6) Domain up and running with SOA_Cluster up and running.
7)     Extended the domain with BAM
The issue revolves when we are doing teh Migration configurations from the console for BAM and we restart BAM server we get an error -
Apr 14, 2011 2:30:35 AM weblogic.nodemanager.server.Handler handleStart
WARNING: Exception while starting server 'bam_server1'
java.io.IOException: Command '/oracle/Shared_MWHome/user_projects/domains/SOA_Domain/bin/server_migration/wlsifconfig.sh -addif eth0 192.168.1.6 255.255.255.0 ' returned an unsuccessful exit code '1'. Check NM logs for script output.
and Bam server goes to Failed Not Restartable state.

The error is clearly out there
java.io.IOException: Command '/oracle/Shared_MWHome/user_projects/domains/SOA_Domain/bin/server_migration/wlsifconfig.sh -addif eth0 192.168.1.6 255.255.255.0 ' returned an unsuccessful exit code '1'. Check NM logs for script output.
This error occurs due to a failure in adding the virtual IP of BAM server to the network interface you have specified in nodemanager.properties.
You need to check whether you have specified the correct interface and subnet mask in node manager.properties as below :
The fourth step is to edit the Node Manager's properties file. This file is called nodemanager.properties
and is located in the ORACLE_BASE/product/osbmw/wlserver_10.3/common/nodemanager directory.
For server migration to work properly, you need to add the properties listed below:
Interface=eth0
NetMask=255.255.255.0
UseMACBroadcast=true
· Interface
This property specifies the interface name for the floating IP (for example, eth0).
· NetMask
This property specifies the net mask for the interface for the floating IP. The net mask should the
same as the net mask on the interface; 255.255.255.0 is used as an example in this document.
· UseMACBroadcast
This property specifies whether or not to use a node's MAC address when sending ARP packets,
that is, whether or not to use the -b flag in the arping command.

SOAP ports with cluster setup and BES?

Okay, our cluster setup in NetWare (yes, still NetWare cluster) with Groupwise 7.0.3 we have unique TCP ports for the client/server (like 1677-something). Even though each clustered node has a unique IP and is running in protected memory.
That being said:
We'd like to enable SOAP for use with BES and GWArchive.
The issue/question:
Do either of these figure out the SOAP port for each PO? Or must the SOAP port be the same among all the PO's for BES to work properly?
If the SOAP port must be the same (I'm not the BES admin, so I don't know if the setup lets you specify just one port or if you can defined them per PO), can you run multiple POA on the same physical host (keep in mind, this is clustered with protected memory) and use the same TCP port # for SOAP?

I haven't used BES, but in general there's no auto-discover method for
SOAP ports, so yes they'd probably have to be the same port.

Display logfiles in cluster setup (HTTPS UI)

Hi all
In my standalone setup, I can display and download logfiles in HTTPS-Webgui under "Log Subscriptions" -> "Log Files".
But in a cluster setup, I can't see the column "Log Files" under "Log Subscriptions". How can I access the files?
Thanks!
Christoph

Hello Christoph,
viewing individual logfiles on the GUI is notavailable for appliances in a cluster. You can still access them via your browser by using:
ftp://appliancename.local
as URL, where "appliancename.local" is the hostname or IP. This will prompt you for an username and password, you can use your normal admin credentials. Also possible:
ftp://[email protected]
ftp://admin:[email protected]
If you want to include username (and password)
Hope that helps,

Network Extender & Cluster Setup

Does the Ingress unit satisfy the GPS signal requirements for other non-Ingress units in a cluster setup?
We have a large steel warehouse that has no cell coverage in the building. I can provide coverage with 3 Network Extenders. However, my problem is going to be the GPS antenna's. I have 1 window that provides a good GPS signal for the 1 extender I have now. If I purchase 2 additional extenders to complete the AoC will each of them have to lock on to GPS too? Or do the non-ingress units not require GPS. It may be wishful thinking, but our only other option is to cut a hole to access the outside & I really dont think these antenna' can handle the environment.
All units will be on the same network switch.

Ah. And I am guessing (really just confirming) that Open Directory is one piece of functionality which is in OSX Server, but not in the basic Snow Leopard distribution.
Sooo, is it worth digging around to see if any of the linux distributions out there contain Open Directory? I have an old lime (333 MHz) iMac in the basement...

Oracle cluster setup

Hi There,
We're trying to build a clustered oracle environment using oracle 11g (11.2.0.1) under Windows 2008 server.
The basic setup is to have 2 servers (active/passive), one shared SAN disk, install the software on both servers, put the database datafiles on the shared disk/SAN and when needed we can switch the shared disk between the 2 servers as failover/failback.
IS the above industry standard cluster setup? or is there a better way of doing it? does oracle/windows provide a way to failover/failback between servers?
Are there any documents that we can read that explains a good cluster setup please (without using RAC)? Or is there a document that have a better setup?
Can someone shed some light on this please and/or point us to the right direction.
Thanks

Does oracle clusterware comes shipped with the specific release (10g, 11g..etc) database installation pack or is it a separate download?
We saw this under the oracle download section:
Oracle Database 11g Release 2 Grid Infrastructure (11.2.0.1.0) for Microsoft Windows (x64)
Download win64_11gR2_grid.zip (715,166,425 bytes) (cksum - 3127109177)
Contains the Grid Infrastructure Software including Oracle Clusterware, Automated Storage Management (ASM), and ASM Cluster File System. Download and install prior to installing Oracle Real Application Clusters, Oracle Real Application Clusters One Node, or other Oracle software in a Grid Environment So, I was wondering if we should download this and install it on the server?
Thanks

Kernel Upgrade of R/3 4.7 Enterprise in Cluster Setup

Hi Experts,
We have a cluster setup with SAP R/3 Enterpirse 4.7 with MSSQL in windows 2003 server with node A and node B. Presently the system is running on Node B.
We also have two application servers (Dialog Instance).
Now I want to upgrade kernel of R/3 system. Please let me know what is the procedure for upgrading the kernel in cluster setup.
Appreciate quick response.
Regards
Sharath

Hi All,
I have successfully upgraded the kernel patch from 640-43 to 640-201 for R/3 4.7 with cluster setup. Currently the system was in Node B.
The only problem which I faced after copying the files to run folder was that the system was not coming up. So we copied back the old kernel files and started the system and it was coming online.
Wen we anayzed the problem we came to know that after copying the latest kernel files the system was not coming up as some DLLs were missing. The Note 684106 - Microsoft runtime DLLs solved the issue. Downloaded the files R3DLLINSTZIP which was given in the note and installed the files and after that my system came up with the latest kernel files.
Hope this will be helpfull for someone in futue.

Simple VPN Setup Fails with "NOTIFY PROPOSAL_NOT_CHOSEN protocol"

Hi,
This is pulling my hair out! Must be overlooking something very simple!
Simple lab setup with 3 routers. VPN setup between R1 & R3 with static routing. R2 connects R1 & R3. All interfaces are reachable, including loopbacks. I am trying to encrypt traffic between loopback on R1 (69.69.69.69) to loopback on R3 (192.168.100.223).
With no Crypto Map applied to outgoing interfaces on R1 and R3 ping is successful (sourced via local loopback) between the loopbacks. As soon as I add the Crypto Map the same ping fails and and I get the following debug messages.

Hi Paul,
"processing NOTIFY PROPOSAL_NOT_CHOSEN protocol 3" indicates the remote VPN peer rejected the phase 2 proposal.
The configuration snippet you have shared here seems fine, ISAKMP and IPSec debugs (debug crypto isakmp and debug crypto ipsec) from the remote VPN peer will be helpful in troubleshooting further.
Following is a useful doc on VPN troubleshooting:

Database bau host in HA cluster setups

In cluster setups for MSSQL, is there a technical term to describe the host that will run specific SQL instances/databases under normal circumstances (i.e. while it is up and doesnt need to be run by another server in the cluster)?

This is the "Primary Node" for the instance. That's not a term that has any technical meaning in a Windows Cluster. You may use cluster failover policies for the instance to help ensure that the instance is normally running on its Primary Node.
You can set the Primary Node for the instance as the "Preferred Owner" in the cluster configuration. This will cause that node to be preferred over other nodes for failover
and failback.

Recomended Cluster Setup?

We are setting up an HA WebApp based on iAS6sp2 and would like some
clustering recommendations. Here is a basic setup:
4 Solaris boxes (Solaris 8) configured like this:
iWS1 has iPlanet WS 4.1sp?? w/iAS WebConnector
iWS2 has iPlanet WS 4.1sp?? w/iAS WebConnector
iAS1 has iPlanet iAS 6 Sp2
iAS2 has iPlanet iAS 6 Sp2
(Note: both iWS's are frontended by a web server director - there is a
pair for redundancy. The backend (behind the iAS instances) is an
oracle db cluster.)
Right now iWS1 and iAS1 are connnected and use and LDAP on iAS1. The
same pattern exists for iAS2/iWS2. Our WebApplication(s) consists of
state oriented JSPs and servlets that use stateless EJBs (ejbs and
servlets live together in iAS (in single KJS)).
We want all combinations of fail overn (the WSD will handle failover
between iWS instances):
iWS1 -- iAS1
\ / |
/ \ |
iWS2 -- iAS2
So session are replicated between iAS instances and iWS instances (well
the WebConnector) can route to either iAS instance. How would one set
this up? In our NT lab (same basic picture w/o WSD), we have done this
via a shared LDAP instance on one of the iAS boxes. However, that LDAP
instance represnets a single point of failure. How does one set up
failover for LDAP 'master'? Or is this even on the right track.
Ultimately, we will have 2 data centers 'north' and 'sourth' that will
have clustered as described above (we call them local clusters). We
will need to failover between the north and south 'local' clusters, and
would like sessions (and cluster data) to replicate (less frequently)
between the north and south, too. Insight into this setup would be good
too..
Thanks for any help.

Hi Fred,
Here is the link, as to how to install a simple two iAS cluster :
http://developer.iplanet.com/appserver/samples/cluster/docs/unix-cluster.html
Just go through it and try instaling both the iAS with a common LDAP.
Note: please do the Custom installation only for both iAS servers.
You can install a backup LDAP server also.
I have attached a file in which what ever the inputs are requred
during enabling the directory replication service, are given. Please
go through it and try installing the LDAP same way.
Note: The steps written in the file are the steps asked by installer,
during Custom iAS installation, after initial common steps.
And i don't think that failover between the two already setup clusters
is possible,
as for a cluster, config parameter (iasconfig) and LDAP server should
be same.
And in a cluster to have a distributed session and a failover support,
you need to deploy the application on all the iAS servers
participating in the cluster.
So if you put the same iasconfig name with common LDAP and app.
deployed on all the servers, than it is like a single cluster, not two
local clusters.
I am working on this, and will get back to you after some time with
some solution.
Meanwhile if you have any other doubts, please feel free to mail me.
Regards,
Sanjeev.
