High Availability setup Single Host multiple OMS Servers in Cluster?

Hi All,
Due to OMS Server JRockit JVM crash
Refer:
EM Grid OMS JRockit JVM crashing with Illegal memory access 54
We are planning to setup one more OMS server in the same host. These two OMS server will be in cluster.
What are the implications? Any problem in setting up OMS clusters in a single host as clustered ? (Client dont have plan to install on multiple host).
I couldn't find any document which mention that we could do OMS cluster
Thanks

For HA confoiguration of the OMS please see http://download.oracle.com/docs/cd/E11857_01/em.111/e16790/toc.htm
For installing an additional OMS please check http://download.oracle.com/docs/cd/E11857_01/install.111/e15838/toc.htm

Sender agreements on high availability setup

Hi
We have XI and ERP exchanging some messages. Our ERP system has been switched to high availability setup.
As for one scenarion in XI: ERP is sender and there is ONE sender agreement that can use ONE communication channel (RFC).
In that communication channel, "RFC Server Parameter" is configured for one of the app servers. "RFC Metadata Repository Peremeters" are set to point to the load balancer.
What happens is that this scenarion can be started only from this app server that is configured in the communication channel.
How to enable that both ERP app servers could be th senders for this scenario?
I am missing something obious...
Thanks,
Heiko

This seems strange for me too. But if I set the RFC Message server and Metadata server to use the same system, the connection will not work.
It seems that there are two possible ways:
- change communication channel so that it would not be app server specific. Tried but don't seem to figure out how this should be configured.
- add multiple sender agreements. XI dos not allow multiple sender agreements... requires different receiver... but there is no receiver at all.
Any ideas?

WL9/bpel10.1.3.4 MLR10 high availability setup missing internal queues.

Hi,
Noticed that setups on weblogic HA (High Availability) cluster setups have a bug in setting up the JMS SOA module.
Currently 2 mandatory queues (distributed) and corresponding Factories are missing: eg BPELInvokerQueue and BPELWorkerQueue.
These queues basically guarantee no message loss during for example http/SOAP communications. Like in our case BPEL <-> OSB.
On non HA setups and probably older versions of BPEL the porting to WL9.2 goes smoother as they do contain these queues/.
Does anyone know putting them manually resolves the problem? Putting Service request on OTN to support this.
Thanks and Regards

Hi,
okay, you can use 4 virtual servers. But there is no need to deploy dedicated server roles (CAS + MBX). It is better to deploy multi-role Exchange servers, also virtual! You could install 2 multi-role servers and if the company growths, install another multi-role,
and so on. It's much more simpler, better and less expensive.
CAS-Array is only an Active Directory object, nothing more. The load balancer controls the sessions on which CAS the user will terminate. You can read more at
http://blogs.technet.com/b/exchange/archive/2014/03/05/load-balancing-in-exchange-2013.aspx Also there is no session affinity required.
First, build the complete Exchange 2013 architecture. High availability for your data is a DAG and for your CAS you use a load balancer.
On channel 9 there is many stuff from MEC:

High Availability Setup

Hello,
We are trying to setup HA environment where master in pool1 crashes , master in pool2 can take over. We are using OEM to manage our environment. Please let us know if you were able to achieve this in your environment.
Setup:
Pool1 has VMServer1 (Master, Utility and Resource) & VMServer2
VMServer1 hosts GuestVM1
Pool2 has VMServer3 (Master, Utility and Resource)
Scenario:
If VMServer1 crashes, GuestVM1 should migrate to VMServer2 or VMServer3 as per the preferred list defined during configuration.
Thanks a bunch
Dani

Please let us know if you were able to achieve this in your environment. What you describe is not possible. Each pool is an independent grouping of servers. You would have to put all three servers into a single pool for a guest to successfully restart on any of them. Also, in Oracle VM 2.2, the pool master role is automatically assumed by another server if the original pool master goes offline.
However, OEM is not yet capable of managing Oracle VM 2.2-based pools. You would need to switch to using Oracle VM Manager, or wait until a patch for OEM is released to achieve this level of HA.

Exchange High availability between two sites with two servers

Hi Team,
I have a requirement to deploy exchange server 2010 between two sites. but i have limited resources to full fill this. below the summary.
2 servers in two sites
different subnets will user for two sites
Need to deploy DAG.
please let me know the considerations for this deployment.
Thank you

Hi - In this scenario, you would setup the following: Site 1: Exchange 2010 Multi-Role server File Share location to place File Share Witness for the DAG Site 2: Exchange 2010 Multi-Role server The above will give you 2 nodes in the primary location and
one node in the secondary location so that resources will stay in Site one. You will also need to enable DAC (Datacenter Activation Coordination) on the DAG so that the Cluster group can be managed by Exchange. Last but not least, you will want to restrict
automatic failover of resources to Site 2 by blocking that action on the Exchange server in Site 2 using 'Set-MailboxServer <servername> -DatabaseCopyAutoActivationPolicy Blocked' This will make you manually failover to site 2 and not end up with resources
there after a sudden failure or issue that is not impacting the entire site.Jason Apt Microsoft Certified Master | Exchange 2010

Edge server high availability and next hop to FE servers

Hi All,
As per the article https://technet.microsoft.com/en-us/library/gg412847.aspx "Each Edge Server is a multihomed computer
with external and internal facing interfaces. The adapter Domain Name System (DNS) settings depend on whether there are DNS servers in the perimeter network. If
no DNS servers exist in the perimeter, the Edge Server(s) use external DNS servers to resolve Internet name lookups, and each Edge Server uses a HOST to resolve the next hop server names to IP addresses."
If i have 3 FE servers with DNS load balancing, where the pool.contoso.com would be associated with 192.168.0.1,
192.168.0.2, 192.168.0.3.
How do i create Host record for front end pool in the edge server? i mean which among the 3 ips should i use? as i can use only one IP in the host file record for a host name.
If i create pool.contoso.com
192.168.0.1 and that server is unavailable then the whole purpose of Edge and FE HA is defeated !!

The same doc says: "Edit the HOST file on each Edge Server to contain a record for the next hop server or virtual IP (VIP) (the record will be the Director, Standard Edition server, or a Front End pool that was configured as the Edge Server next hop
address in Topology Builder). If you are using DNS load balancing, include a line for each member of the next hop pool."
But you're right, it was my understanding that only the first line of the hosts file was used. I'd have to presume the application is somewhat intelligent about this or it's incorrect guidance. I've never tested it.
You could use internal DNS too, resolving the issue, but if your DMZ was ever penetrated, someone could potentially use DNS to help map out your network. Otherwise, you'd want to add a DNS server in your DMZ or use HLB just for this which I wouldn't
be in love with.

Jabber High Availability Setup

Hi,
I'm working on a deployment of IM&P Server v9.1 with a publisher and a subscriber in a cluster, I've configured HA for the cluster and it is working fine (when the pub goes down no one gets disconnected and all the chat services work fine) but I have a question about the configuration in the jabber software for windows, ios, android, etc:
Let's take a look to the jabber desktop for windows, when you configure the ip address of the server, what should you configure there??? in my case I've configured the ip add of the IM&P Pub and my users worked fine with all the services BUT if the pub goes down no one can login using the jabber (this make sense since is the pub add the one that the users are looking for in that config) unless I configure in this screen the ip add of the Sub.
Is there a configuration that can be done in order to have this automatic???
Thanks in advance for your comments.

Thanks alot for your comment!
Just one question, besides this DNS SRV config what do I need to configure in the IM&Presence Server in order to have this working???
How can I make jabber to know when to use one record or the other??
Thanks in advance for your help.

Listener setup when using multiple databases on same cluster

Hi,
In our 2-node RAC cluster, we have 5 databases running on the same cluster. Since we are using SCAN listener on port #1521, does this mean db port# for all databases is 1521?
If I decide to use a unique port# (other than SCAN port#), what are the choices?
ENV: 11gR2, 2-node RH 5.x
Thanks!

The answer to your question depends on how it was configured.
My recommendation ... run some tests and see if that is the way it was done.

JSPM in high availability

Dear Friends,
I have installed PI 7.1 in High availability using Microsoft windows MNS based cluster. It was with initial patch level 04 of Netweaver 710.
I have installed SCS, ASCS, Enque Replication Services etc in cluster mode. I have installed primary application server on Node 2 and Additional Application server on Node 1.
Now I installed SP07 using JSPM from my Primary Application server i.e. Node 1. It went successfully and my support Pack level was upgraded to Sp07. But now when I open Java stack in Node 1, It shows only home page using url - http://10.6.4.178:50000
After that if I open any link e.g. UME or NWA, it does not open and throughs following error :
Service cannot be reached
What has happened?
URL http://10.6.4.178:50000/wsnavigator call was terminated because the corresponding service is not available.
Note
The termination occurred in system PIP with error code 404 and for the reason Not found.
The selected virtual host was 0 .
What can I do?
Please select a valid URL.
If it is a valid URL, check whether service /wsnavigator is active in transaction SICF.
If you do not yet have a user ID, contact your system administrator.
ErrorCode:ICF-NF-http-c:000-u:SAPSYS-l:E-i:sappicl1_PIP_00-v:0-s:404-r:Notfound
HTTP 404 - Not found
Your SAP Internet Communication Framework Team
Java is started properly on both the nodes without any error. While it is working fine on Node 2 i.e. 10.6.4.179.
Please suggest ! Do we need to do so special step for installing patch through JSM in High availability setup?
Jitendra Tayal

Hi Jitendra,
While doing a patch upgrade with JSPM in HA scenario, you need to switch off the automatic switchover option because, once the components are deployed, the J2ee gets restarted. If the automatic failover is active, the service gets switched over to the other node.
In this case, shutdown all the instances and stop the cluster.
Restart the systems. Start the cluster in the original servers.
Restart JSPM.
It should work fine then.
Let me know if it is helpful.
Best Regards

High Available SRW2024

I trying to create a high available setup using two SRW 2024 switches and Linux bonded network adapter in mode 1. Each network adapter of the bond is connected to a switch and in case of failure of an adapter or switch, the bonded network adapter will fail over to the other switch using the same MAC address.
I have an aggregated link setup between the two switches. Furthermore I have spanning tree enabled on both switches. If I do a fail-over test and the bond fails over to the other switch, the port state of the aggregated link changes to blocking which blocks all traffic between the two switches.
In case I use a single (none aggregated) link I’m able to prevent the blocking by disabling spanning tree on the inter switch port. In this case the switch needs about 10 seconds to learn the new port of the MAC address. However I’m not able to make this work on an aggregated link. The UI does have the option to disable spanning tree on the aggregated port, but when saving spanning tree is still enabled.
Questions:
1. What is the recommended setup concerning inter switch aggregated links and spanning tree configuration for above mentioned high availability configuration.
2. Why is it not possible to disable spanning tree on aggregated links? Is this by design or is there some problem with the UI?
Any help appreciated.

I have rapid spanning tree enabled on both switches.
The problem is that I have to disabled spanning tree on the link connecting the two switches together. If not the inter switch link will be blocked the moment I fail over the network bond because it probably thinks there is a redundant path. Is there some other way to prevent the inter switch link from blocking?
If not, how can I disable spanning tree on the aggregated link? So far I only managed to do this on a normal link, but cannot do it on an aggregated link.

Generating license for ISE high availability primary/secondary nodes

We have two ISE servers that will act as primary/secondary in a high availability setup.
The ISE 1.0.4 installation guide, page 93, mentions that "If you have two Cisco ISE nodes configured for high availability, then you must include both the primary and secondary Administration ISE node hardware and IDs in the license file."
However, after entering the PAK in the licensing page, the only required fields are:
- Primary Product ID
- Primary Version ID
- Primary Serial No
In this case, how can i include both primary and secondry HW and IDs?
Thanks in advance.

I am refering you a Cisco ISE Nodes for High Availability configuration guide, Please check:

BIA Load Check delivers wrong result for high availability

Hi all,
has anyone noticed the BIA Load Check (Function CHECK_BIALOAD_CHECK of class CL_RSDDTREX_SERVICE) handles a high-availability setup in the wrong way?
We have 2 times x blades, with each blade being mirrored in a high-availability setup (dedicated backup mode).
That means our usable space is: x * memory_size of blade
However, the load check calculates the load by doing:
load_factor = size_of_all_indexes / SUM(memory_per_blade)
=> If we have 36 GB/blade and 2 blades + 2 backup blades, total usable memory should be 236 = 72, and NOT 436 = 144!
So the CALCULATED load_factor is only half of the ACTUAL (real) load factor => the alerting for BIA overload is never triggered!
Do we need to write our own load check function then?
Thanx,
Hendrik
Edited by: HMaeder on Jan 20, 2010 5:44 PM

Hello Hendrik
I believe your finding is correct. Backup blades should not be taken into consideration for total memory. Please open a customer message so SAP development can analyze the issue and provide a solution (just cut&paste your posting).
