Two Catalyst 4500 high Availability

Hi,
I´m trying to desing a high Availability topology with two 4500, in this moment the company a 4500R-E with a supervisor 6e, and we are considering a second switch 4500R+E with supervisor 7E, is possible to interconnect both switch in high Availability with GLBP? and if is possible how is the connection between both supervisors?
Regards,

GLBP I believe is supported on 4500 L3 sups.
How to interconnect them depends on what you're trying to accomplish. Since you want to use GLBP, you'll need an uplink to both 4500s from an edge switch. There are several ways to provide redundancy.
If you intend to span VLAN beyond a single edge switch, you'll want to sync your ARP and MAC-table timers to avoid unicast flooding.

2xC350 in High Availability Mode (Cluster Mode)

Hello all,
first of all, i`m a newbie in ironport. So Sorry for my basic questions, but i can`t find anything in the manuals.
I want to configure the two boxes in High Availability Mode (Cluster Mode) but i don`t understand the ironport cluster architecture.
1) in machine mode i can configure IP-Adresses -> OK
2) in Clustermode i can configure listeners and bind them to a IP-Address -> OK
But how works the HA?
A) Should i configure on both boxes the same IP to use one MX Record? And if one box is down the other takes over?
B) Or should i configure different IPs and configure two MX Records?
And if one box is down the second MX will be used.
Thanks in advance
Michael

The ironport clustering is for policy distribution only - not for smtp load mgmt.
A) Should i configure on both boxes the same IP to use one MX Record? And if one box is down the other takes over?
Could do - using NAT'ing on the f/w but few large business take this approach today.
Many/most large businesses use a HW loadbalancer like an F5, Foundry ServerIron, etc. The appliances themselves would be set up on seperate IP addresses. Depending on the implementation requirements, the internal IP address could be a public IP or a private IP.
B) Or should i configure different IPs and configure two MX Records?
And if one box is down the second MX will be used.
If you set up two boxes, even with a different MX preference, mail will be delivered to both MX records. There are broken SMTP implementations that get the priority backwards, and many spammers will intentionally attempt to exploit less-restrictive accept rules on secondary MX recievers and will send to them first.

ACE - Port-channel High Availability

We have configured two ACEs with high Availability. ACEs link with our cores, switches cat6500, through a port-channel, ACE’s ports G1/1 and G1/2. High availability works fine if some vlan down but it doesn’t work if an interface down, only if both interfaces get down because then, all vlans of the channel port get down two.
If possible get an interface port-channel high availability?
Thanks for your help in advance.

Thanks for your answer. I have two Cat6500, no VSS possibility. I have two ACEs so each one has configured a port-channel with one Cat6500 (two ports). It works fine. Any problem with that. My issue is when one port-channel of both port is down, failover doesn’t works then, only if both ports are down or vlans are down. I think high availability is only possible in vlan interfaces, not in physical interfaces.
Regards my friend.

Catalyst 4500-X, VSS, and SVI

Hello, everybody!
I have a proyect to implement the feature VSS, with two catalyst 4500-X, it will be the layer Core/Distribution.
So, I want integrate in the catalyst 4500X, Inter vlan routing (SVI) and vtp domain, in the layer access, we´ll have SW 3750-X with PoE.
Is possible configure SVI in my catalyst 4500-X. to separate traffic across VLANs. and the routing will be in the 4500X too. ???
My customer does not have sufficient space to mount the serie 4500E in the Rack, so he prefer the 4500-X.
Help me!
Thanks!
Regards

Hi,
Is possible configure SVI in my catalyst 4500-X. to separate traffic across VLANs. and the routing will be in the 4500X too. ???
Yes, there is no different between a VSS pair and non-VSS when it comes to SVI and inter-vlan routing. It works the same way as if the 4500-X ware separate.

Two WLC 5508 Anchor High Availability

Hello.
It's possible use 2 WLC 5508 en ANCHOR MODE in a Active-Active scenario?.
For example, if one WLC get down of service, the other one keep provide service to the anchor clients?.
In this moment we have just one WLC 5508 in Anchor Mode. What i need to configure a ANCHOR high Availability.
Thanks A lot!!!

This is confusing to me:
If we install a second Anchor WLC, what you recommend about the DHCP server in a failover event, because this second ANCHOR WLC will have the same configuration of the firts anchor wlc.
What do you mean the two will have the same configuration? The hostname and ip should be different.... or are you just stating that the WLAN and DHCP will be the same? I don't want to tell you something and break your environment, so just trying to clear things up.
Thanks,
Scott

Configuring two 11g OID servers in High Availability mode.

I have OID1 server where I have installed OID11g and WLS using SSL Port 3131 and Non SSL Port 3060. The ldap set up is working as the sqlnet connections are using ldap adapter to resolve the request.
I have OID2 server where I have installed OID11g using the same port.
Now, I want to setup a cluster for these two so that the the load balancer will automatically route the requests to either of the two servers so that if one is unavailable, the other will fill the request. I am following "Configuring High Availability for Identity Management Components" document, but it is not very what steps needs to be followed.
Any suggestion will be appreciated;
I am also having problem using ldapbind or any of the oid commands as it gives "unable to locate message file: ldap<language>.msb" despite the fact that I am seting all the env vars such as ORACLE_HOME, ORACLE_INTANCE, ORA_NLS33 and so on.

You don't need to setup a cluster for Load balancer. The Load balancer configuration can point to both the server and depending on the configuration in LBR act in failover and load balanced mode. All you need to take care of is that the two OID servers are using the same schema.
When installing first OID server it gives a option to install in cluster mode and when installing the second server you can use the option to expand the cluster created in first installation. But that should not stop you from configuring OID in highly available mode using Load balancer as explained above.
"unable to locate message file: ldap<language>.msb" occurs if you have not set the ORACLE_HOME variable. See that it is set to <MiddlewareHome>/Oracle_IDM1 if you have used the defaults.
Hope this helps,
Sagar

How to configure two TMG 2010 Standard Edition for High Availability

I've classic scenario.
TMG2010 as Edge Firewall, with two NICs, one from ISP and the other for LAN.
I've standard edition, and i want to setup two TMG2010.
Can i create some high availability with these two tmg2010 in some way??
maybe some NLB?? to share their internal IP and Public IP?
in case that TMG01 fails, the services to be offered by TMG02?

High Availability with two 5508 WLAN controllers?

Dear all,
we are considerung to implement a new wireless solution based on Cisco WLC 5508 and 1262N Access Points. We are planning to purchase about 30 access points and have two options: Either purchase one WLC 5508-50 or, for redundacy, two 5508-25 controllers.
Is it possible to configure two WLC 5508 as a high availability solution so all Access Pointes are distributed over both WLCs and in the case one WLC breaks the other one manages all APs?
If we have 30 access points and one of two WLC 5508-25 breaks of course not all 30 but only 25 access points can be managed by the remaining one. Is there some sort of control to choose which access points shall be managed and which not?
How does such a configuration look like in general, is the implementation of a two controller setup rather complex or straight forward?
Thanks!
Michael

Dear Nicloas,
thanks for your reply. We have an offer where two 5508-25 are only a little more expensive than one 5508-50. So I think it's better so spend a little more money and have a backup WLC. Otherwise, if the one and only WLC breaks, all APs are unusable which would not be acceptable for us.
Regarding roaming - not all access points will distribute the same WLAN. Actually we will have one wireless network with 18 access points for our warehouse and 12 access points for the internal and guests network.Therefore no roaming will happen between those APs. In this case I could use one WLC for the 18 warehouse access points and 12 for the internal network. In the case one controller breaks, I could use the remaining one for the important warehouse systems (i.e. by using the priority system).
Regarding the configuration: If I understand correctly I configure both controllers exactly the same (except for the name and IP address of course) and put both controllers in the same mobility group - and that's really it? Sounds great!
I have one general question regarding the new WLC controllers: Is it true that communication between the WLC and the APs is now done on Layer 3 only so all APs need an IP address? I'm asking because currently we are still using an Cisco 4112 WLC which operates in Layer 2 mode. So I guess with the new WLC, I have to configure DHCP option 43 with the management IP address of the WLC, right? I also guess I can manually move APs from one to another WLC once they have joined a controller for the first time?
I'm ordering the book "Deploying and Troubleshooting Cisco Wireless LAN Controllers" now and guess this will answer most of my upcoming questions. Can I come back to you here in case I run into trouble with the configuration?
Thanks a lot for your help

11.1.2 High Availability for HSS LCM

Hello All,
Has anyone out there successfully exported an LCM artifact (Native Users) through Shared Services console to the OS file system (<oracle_home>\user_projects\epmsystem1\import_export) when Shared Services is High Available through a load balancer?
My current configuration is two load balanced Shared Services servers using the same HSS repository. Everything works perfectly everywhere except when I try to export anything through LCM from the HSS web console. I have shared out the import_export folder on server 1. And I have edited the oracle_home>\user_projects\epmsystem1\config\FoundationServices1\migration.properties file on the second server to point to the share on the first server. Here is a cut and paste of the migration.properties file from server2.
grouping.size=100
grouping.size_unknown_artifact_count=10000
grouping.group_by_type=Y
report.enabled=Y
report.folder_path=<epm_oracle_instance>/diagnostics/logs/migration/reports
fileSystem.friendlyNames=false
msr.queue.size=200
msr.queue.waittime=60
group.count=10000
double-encoding=true
export.group.count = 30
import.group.count = 10000
filesystem.artifact.path=\\server1\import_export
I perform an export of just the native users to the file system, the export fails stating and I find errors in the log stating the following.

I go and look for the path that it is searching for "/server1/import_export/msr/PKG_34.xml" and find that this file does exist, it was infact created by the export process so I know that it is able to find the correct location, but it then says that it can't find it after the fact. I have tried creating mapped drives and editing the migration.properties file to reference the mapped drive but it gives me the same errors but with the new path. I also tried the below article that I found in support with no result. Please advise, thank you.

it is not possible to implement a kind of HA between two different appliances 3315 and 3395.
A node in HA can have the 3 persona.
Suppose Node A (Admin(primary), monitoring(Primary) and PSN).
Node B(Admin(Secondary), Monitoring(Secondary) and PSN).
If the Node A is unavailable, you will have to promote manually the Admin role to Primary.
Although the best way is to have
Node A Admin(Primary), Monitoring(Secondary) and PSN
Node B Admin(Secondary), Monitoring (Primary) and PSN.

Office Web Apps farm - how to make it high available

Hi there,
I have deployed OWAs for Lync 2013 with two servers in one farm. When I was testing, e.g. the case when other server is down I found out the following error:
Log Name:      Microsoft Office Web Apps
Source:        Office Web Apps
Date:          17/03/2014 22:59:54
Event ID:      8111
Level:         Error
Computer:      OWASrv02.domain.com
Description:
A Word or PowerPoint front end failed to communicate with backend machine
http://OWASrv01:809/pptc/Viewing.svc
Does that means, that OWAs cannot setup as high avaiable when using standalone OWAs only? Above error appeared when the server OWASrv01 was rebooting.

Hi Petri,
For your scenario, you have achieve a  high performance for your Office Web Apps farm but not high availability.
For performing a high availability Office Web Apps farm, you can refer to the blog:

High Availability of BPEL System

We are having a High Availability architecture configuration for the BPEL System in our production environment.
The BPEL servers are clustered in the middle tier of the architecture and RAC is used in the database tier of the architecture.
We have 5 BPEL processes which are getting invoked within each other. For eg:
BPELProcess1 --> BPELProcess2 --> BPELProcess3, BPELProcess4 &
BPELProcess4 --> BPELProcess5
Now when all the above BPEL processes are deployed on both the nodes of the BPEL server, how do we handle the end point URL's of these BPEL servers.
Should we hardcode the end point URL in the invoking BPEL process or should we replace the IP address of the two nodes of the BPEL server with the IP address of the load balancer.
If we replace the IP address of the BPEL server with the IP address of the load balancer, it will require us to modify, redeploy and retest all the BPEL processes again.
Please advise
Thanks

The BPEL servers are configured with active - active topology and RAC is used in the database tier of the architecture.
BPEL Servers is not clustered. Load Balancer is used in front of the two nodes of the BPEL servers.

Synchronous File Read in a High Availability Scenario

Hi All,
We have Oracle SOA Suite 10.1.3.4 which is a High Availability instance. As per Oracle's doc Id 730515.1 we have edited the bpel.xml file with the property for Adapter cluster only in the cases where a BPEL process was polling for a file and instantiating the process to avoid the race around condition.
However, we have not made this change for BPEL process which contain a synchronous read. As I understand, such processes(which contain a synchronous read) are already instantiated before the file is read and hence the race around scenario does not exist.
Please correct me if my understanding is incorrect. Also, will I need to make any changes for the process in such a case.
Thanks and regards.

Hi Marcio,
The Oracle Document I mentioned available on Metalink states:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Applies to:
Oracle9i AS Integration Platform - Version: 10.1.3.3
Information in this document applies to any platform.
Goal
You have installed BPEL cluster. However, you expect that adapters doing the same work on two different nodes might encounter a race condition. So you would like to configure a singleton adapter. This note describes how to do it.
Solution
1. In collaxa-config.xml change from
<property id="clusterName">
<name>Cluster Id</name>
<value>machine_name:port</value>
<comment>
to
<property id="clusterName">
<name>Cluster Id</name>
<value>bpelCluster</value>
<comment>
The value: 'bpelCluster'
can be anything but has to be the same on both instances.
2. Multicast host and port in jgroups-properties.xml have to be same on both instances.
3. To enable a singleton adapter add the following property in bpel.xml of the process using the adapter in question:
<property name="clusterGroupId">adapterCluster</property>
where the actual value - 'adapterCluster' in this case can be anything but has to be different from the value used before (bpelCluster) when configuring BPEL cluster. The reason for that is that BPEL engine and an adapter will use different communication channels.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I would Like to know if this is applicable incase we have a BPEL Process which contains a synchronous read.
Thanks and Regards.

Exchange 2010 to Exchange 2013 Migration and Architect a resilient and high availability exchange setup

Hi,
I currently have a single Exchange 2010 Server that has all the roles supporting about 500 users. I plan to upgrade to 2013 and move to a four server HA Exchange setup (a CAS array with 2 Server as CAS servers and one DAG with 2 mailbox Servers). My
goal is to plan out the transition in steps with no downtime. Email is most critical with my company.
Exchange 2010 is running SP3 on a Windows Server 2010 and a Separate Server as archive. In the new setup, rather than having a separate server for archiving, I am just going to put that on a separate partition.
Here is what I have planned so far.
1. Build out four Servers. 2 CAS and 2 Mailbox Servers. Mailbox Servers have 4 partitions each. One for OS. Second for DB. Third for Logs and Fourth for Archives.
2. Prepare AD for exchange 2013.
3. Install Exchange roles. CAS on two servers and mailbox on 2 servers. Add a DAG. Someone had suggested to me to use an odd number so 3 or 5. Is that a requirement?
4. I am using a third party load balancer for CAS array instead of NLB so I will be setting up that.
5. Do post install to ready up the new CAS. While doing this, can i use the same parameters as assigned on exchange 2010 like can i use the webmail URL for outlook anywhere, OAB etc.
6. Once this is done. I plan to move a few mailboxes as test to the new mailbox servers or DAG.
7. Testing outlook setups on new servers. inbound and outbound email tests.
once this is done, I can migrate over and point all my MX records to the new servers.
Please let me know your thoughts and what am I missing. I like to solidify a flowchart of all steps that I need to do before I start the migration.
thank you for your help in advance

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:

URL to be used in high availability for Directory Server

Hi All,
I have an environment configured for high availability. I have two OVD and OID servers each in this environment, configured in high availability. What should be the value in the Server URL field of the Directory Server IT Resource in the OIM for this environment? In the normal environment, I had it as "ldap://ovdhost01:6501" and it was working fine. But since there are two servers here, I am not sure what URL to use in place of this. The entry for the two ovd hosts in the OHS is "idstore.com" which is configured on 6501 port. But I tried using the following URLs and none of them worked:
1. idstore.com
2. ldap://idstore.com
3. ldap://idstore.com:6501
4. ldap://ovdhost01:6501,ldap://ovdhost01:6501
Can someone help me know the correct URL to be used in this case?
Thanks,
$id

Not sure about OVD or OID but for SOA and OIM:
SOA:
XMLConfig -> XMLConfig.SOAConfig -> SOAConfig
Rmiurl -> t3://soahost1:soaport1,soahost2:soaport2
Soapurl -> Load balancer or web server url (without the /workflow context)
OIM:
XMLConfig -> XMLConfig.DiscoveryConfig -> Discovery
OimFrontEndUrl -> Load balance or web server url (without the /oim context)
And ofcourse on your LB or WebServer, you need to configure these:
SOA: http://docs.oracle.com/cd/E23943_01/core.1111/e10106/ha_soa.htm#CHDDJEGD
OIM: http://docs.oracle.com/cd/E21764_01/core.1111/e10106/imha.htm#BGBDFEIE
