CSM - serverfarms configured with multiple probes

Hi - If a serverfarm is configured with multiple probes, do the servers within the farm remain active if they respond positively to both probes or do they just need to respond to one of the configured probes?
Thanks in advance

Both probe must respond positively to make the server appears as OPERATIONAL.
If only one probe is responding positively then the server is considered DOWN
That is usefull for UDP test :
you need to check taht you don't have a RST when openning an UDP connection ( the UDP port is not closed) and you need to make ping (in order to be sure that there is a server ;-) )

BSPs configuration with multiple apps servers

Hi Masters,
This is regrarding configure ICM and BSPs on our production box with multiple application servers.
We have our production box in a cluster environment.
The central instance is dbciSAP and apps servers are sapaps2 thru sapaps6. The database is on shared disks. Whenever the central instance fails sapaps2 takes the control and become as dbciSAP but the main dbciSAP never become a application server when ever sapaps2 acts as dbciSAP. Since we have configured load balancing concept in production environment the users can login to system thru any application server. This is waht our environment.
As part of our production box to SAP 4.7 upgrade from 4.6C, we are asked to configure the environment to deploy BSPs. We have successfully configured and deployed the BSPs in our DEV and QAS system (Both are central instances with no application servers) except production box which is due in the next month.
The process we follow to activate BSPs is as follows:
1.Define an ICM service port in /etc/services file.
2.Add the ICM related parameters in instance profiles.
3.Make sure the ICM status is active in SMICM tx.
4.Activate the BSP services in SICF as per OSS note 571484.
Now, the question is how to configure the same ICM service and activate the BSPs since we have multiple multiple application servers.
Subsequently What I am enquirying is:
Do I need to define ICM service ports on each and every hosts where the application servers are running?
Do I need to make changes to each and every instance profile of the application server?
What are the differences in configuring ICM services on central instance and application instances?
Appreciate any help in this regard.
Thanks and Regards
Murty Patchipala

Grasshopper,
I think what you should really read up on is the SAP WebDispatcher. If are serious about running BSP/ICM across multiple app servers, this is the key technology:
http://help.sap.com/saphelp_nw04/helpdata/en/42/5cfd3b0e59774ee10000000a114084/frameset.htm This may also answer some of your questions about profile parameters.
Other than that I can share what we did. We did activate the ICM and services on all app servers and central instance. The service ports of the individual servers aren't that important now because of the WebDispatcher (at least they aren't visible to the user).
Yes we did make some of the ICM profile changes in each instance profile. If your settings are the same, consider using the default profile. Are their particular settings you are interested? I will look over ours, but I don't remember any huge differences from APP server to Central Instance.

Single Nexus 5548UP- FCoE configuration with multiple server ports

Hello Everyone,
I am new to Networking so please bear with me.
Here is some background information. We have a SINGLE Nexus 5548 UP switch to which we are connecting both the storage and the UCS C240 M3 servers (with CNA). Both the storage and server has 2 ports each going to this nexus switch.
We want to implement FCoE with this solution.
Below are the steps (for server ports) that I have followed to configure the nexus. But the port not logging into the SAN (no flogi) with the config.

Fixed the issue. "switchport trunk native vlan 6" was causing the issue. Maybe the storage and Servers were not configured with proper VLAN's. I removed the native vlan and everything logged in fine.
Any how I have configured a single zone with all 3 servers pWWN's. I know single initiator zoning is the way to go.
Can you please guide me if I can move these servers in their separate zones without any outages? If it helps, all severs have 2 pWWN's. The current zoneset is active with that single zone.
Please let me know if you need any additional details.

Event configured with multiple receivers

We have a business object event(say service order technically completed) configured (SWETYPVor SWE2) in our system for two receivers, one a workflow and another is just DUMMY with custom receiver function module. What we are noticing is that the events meant for the DUMMY receiver are going to the workflow receiver.
How do we route the event to the appropriate receiver? Sometimes, the event raised is relevant for the DUMMY receiver and other times, it is relevant for the workflow receiver.

Hello,
You say:
"What we are noticing is that the events meant for the DUMMY receiver are going to the workflow receiver."
I'm not sure if that's the right way to look at it. An event just exists, it's other processes and objects that listen out for it.
What they do with that event is up to them. If you want to differentiate then either create separate events or provide a parameter that the recipient can test for.

Extending Guest Wifi with Multiple Base Stations

The 7.6.3 firmware update reports this new feature:
"The ability to extend the Guest Wi-Fi network on a network that is configured with multiple AirPort Base Stations"
http://support.apple.com/kb/DL1617
I assumed that this meant that an Airport Express was able to "Extent" the guest wifi network. However, I am not able to get this to work. Having entered all the details I just get the orange light and the message that it was unable to extend the network - check the details. I have checked them multiple times and still not working. If I switch to extending the "main" network then it works first time, but does not extend the guest as far as I can see.
If I set up from scratch it picks up the guest network and tries to extend but then switches to the main wifi later in the process after claiming to extend the base station itself, not one of the wifi networks.
What does this update mean?! Has anyone managed to "extend the Guest Wi-Fi network" in any way?
All devices have been updated to 7.6.3 and all airport utilities have been updated to the latest version (6.2).
I am running an extreme as the main router then I have a number of expresses to extend round a large building, but it is the guest that needs extending!!
Any help would be much appreciated!
Adam

I am running an extreme as the main router then I have a number of expresses to extend round a large building
You need to have the "new" AirPort Express to be able to extend the Guest Network. The "new" Express looks like a miniature AirPort Extreme.
Check the Model No on the side of the AirPort Express devices that you have. If you see A1264 this is an older version of the Express that does not have Guest Network capabiltiy.
Using an AirPort Extreme and new AirPort Express here., the Guest Network "extends" just fine when I try this using wireless only. I also have another AirPort connected back to the main AirPort Extreme using a wired Ethernet connection. The Guest Network is extended on this device as well.

Failure when FWSM in transparent mode with multiple contexts

hi experts,
We have two FWSMs working in active/standby state, configured with multiple contexts in transparent mode. and the "outside" and "inside" interfaces for each context are in same subnet.
Now we have one FWSM broken and the RMA part can't arrived in short time, so we have the risk that the sencond FWSM could be failed as well. In the worst case if the two was broken or powered off simultaneously, i wonder that if the communications between multiple contexts could be ok???
thanks in advance.

Mesh with multiple countries on the controller

Hi,
I have a central controller configured with multiple countries .
At one site I plan to configure a mesh network.
I know there was a problem with mesh and multiple countries in the past.
Is there still a problem with a 5508 that runs on
Software Version 7.6.130.0 ?
Best Regards,
Marc

Yes, I do not think even in 8.0.x code multiple country code supported for mesh deployments.

CSM health probe for server farm with multiple vservers

Is there a way to specify the vserver port that a health probe monitors when multiple vservers are configured for the same serverfarm? Let's say I have a serverfarm named farm1. farm1 services two ports www and https so two vservers vserver_www and vserver_https are configured and bound to farm1. I would like to enable http health probe on farm1 with the intention of only monitoring vserver_www http port but, instead, the health probe monitors both www and https and since a http probe on https fails it takes farm1 reals and both vservers vserver_www and vserver_https out-of-service. Is there a way to configure a health probe to monitor a specific port? Or, should I create two duplicate serverfarms farm1 bound to vserver_www and farm2 bound to vserver_https and only enable http health probe on farm1? Any other ideas welcomed.

Appreciate the feedback. I also found what I was looking for in configuration examples. To summarize I've borrowed the comment from the URL below:
# The port for the probe is inherited from the vservers.
# The port is necessary in this case, since the same farm
# is serving a vserver on port 80 and one on port 23.
# If the "port 80" parameter is removed, the HTTP probe
# will be sent out on both ports 80 and 23, thus failing
# on port 23 which does not serve HTTP requests.

ACE: a class-map with multiple ports... what about the probe/serverfarm?

Hello Gilles,
One question about something I was not able to find in the documentation.
Lets say I have one class-map which includes 2 ports (in this case https and 5061).
Can I associate this class-map to just 1 generic serverfarm and probe for both ports or I have to specify 2 serverfarms/rservers/probes?
So, by not specifying the ports on the rserver, if a request is received on port 443 (or 5061), it is sent to the same respective port on the rserver?
The same way is valid for the generic probe. ACE module is able to probe both ports based on the class-map?
Thanks and have a great day!!
Giulio.

Even if you use the 4710 appliance or expect the inheritance in the module software, it's worth considering if this is really what you want. If you keep multiple ports in the L3/L4 class-map you can't handle the services independently. You will have a common serverfarm for both https and 5061. If https service stops on one rserver, the ACE will place that rserver (and not that service) in out-of-operation state and it won't receive any 5061 traffic either. (You have the fail-on-all probe option but I wouldn't say it's a better choice. In that case, https traffic would be sent to the rserver even if https port is closed as long as there is at least one working service on it.) That's why I prefer a separate class-map and separate serverfarm for each service. (They can contain the same rservers, no need to duplicate.) BUT if the software supports probe port inheritance, you can benefit from it even in this scenario: serverfarm-443 and serverfarm-5061 can both use your PROBE_GENERIC_TCP.

Bridge mode CSM - Serverfarm with hosts in different vlans

Hi,
I'm trying to answer a question while doing design. I am planning on deploying a CSM in bridge mode with multiple vlans. I need to create a serverfarm which has real servers in two separate server side vlans.
I would then present the Vserver on the client side only of one of the vlans (I always like to specify where I want the vserver). Whe traffic comes in to this vserver, will the CSM appropriately switch traffic to both vservers? I think it will but don't have access to a csm right now to mock it up.
Thanks
Adam

You cannot have 3 vlans configured in bridge mode with all vlans using same address space.
You can use mixed mode to achieve your goal.
It is possible to have Vlan 10 and Vlan 11 in bridge mode and at the same time have VLAN 12 (for example) in the routed mode.
- Traffic from vlan 10 to vlan 20 is bridged
- Traffic from vlan 10 to vlan 12 is routed
where Vlan 10&20 belong to same subnet and Vlan 12 is in different subnet.

CSM - multiple probes behaviour

On a CSM, if there is more than one probe configured on a serverfarm, lets say 3 probes, ping, http and port 4400, if one of these probes fails then is the real server marked as failed, or do all 3 probes have to fail before the server is marked as failed, or is the specific service on the real server marked as down ?
Thanks in advance.

Dear Peter,
If you associate a probe of a particular type (http, icmp, etc)with a server farm containing real servers that are not running the corresponding service, the real servers send error messages when they receive a probe of that type. This action causes the CSM to place the real server in a failed state and disable the real server from the server farm.
If any of the probe failed, It will fail the real server.

Anser

How to configure one TREX host with multiple index servers ?

Hi All,
Does anyone know how to configure TREX on the one host,
with multiple index servers ?
Reason for this is to make better use of resources available on the host server(4 Gig, 4 Processor, Windows2003), to improve the search performance of
our KM content for portal users.
I am using TREX 7 and have not been able to do this,
despite reading the Single and Distributed install
documentation.
Any help would be appreciated.
Regards,
Andres

Hi Andres,
To make use of the RAM a Server provides you have to run two indexserver processes (each can then consume 2 GB);
Proceed like this:
1. Go to TREXdeamon.ini; check if section [indexserver2] is there (it is already provided, but not active in standard installation)
2. In TREXdeamon.ini go to
[daemon]
references sections below
programs=nameserver,preprocessor1,indexserver1,queueserver,alertserver
and add indexserver2 here. Restart TREX; second porcess is then started; can be checked in TREX monitor in Portal as well
3. To distribute existing indexes to the new process, start TREXadmintool and go to Index: Landscape
Go to the last two columns and move the indexes (move master here/secondary mouse click)
If you don't distribute the indexes the new index server process will be regarded when an new index is created.
Hope this helps!
cheers

Does CISCO C3560X VLAN support multiple Network segments which are further configured with HSRP function

Hi Cisco experts,
My name is Kumagai and I need your expert opinions below.
I am trying to configure one VLAN1 support multiple network segments as below.
(this should be a very straight forward configuration and should be OK, I think ? )
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
The only issue that is eating me is the above network segments are using HSRP too
and I am not sure is this possible with a combination of VLAN1 supporting multiples which are
further supported with HSRP settings in Cisco environment.
!example of HSRP:
interface Vlan4
ip address 172.30.4.253 255.255.255.0
no ip redirects
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
<<< what will happen if I add the HSRP configuration as below into the above VLAN1 with multiple Network segment ??)
I would like to summarize my "Combined" configurations as below but I need your expert opinions on
whether the configuration below is workable without any problem ??
Or it is a total flop because Cisco does not support the configuration below !!!
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
standby 30 ip 172.30.31.254
standby 30 priority 105
standby 30 preempt
standby 60 ip 172.30.61.254
standby 60 priority 105
standby 60 preempt
standby 70 ip 172.30.71.254
standby 70 priority 105
standby 70 preempt
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
Thanking you in advance !!!!!

Hi,
As far as i know we dont set the ip helper address on the radio interface. It should be on the L3 interface of corresposding VLANs i.e.
int vlan 20
ip helper-address 192.168.33.xxx
int vlan 60
ip helper-address 130.20.1.xxx
I'm assuming that your using SVI's (int Vlan 20 and int Vlan 60) rahter than physical interfaces. Also hope you have configured switch port as trunk where this AP is connected.
Modify the AP config as below since you are using data vlan as the native vlan
interface Dot11Radio0.20
encapsulation dot1Q 20 native
interface FastEthernet0.20
encapsulation dot1Q 20 native
Ideally your AP fastethernet configuration should looks like below and not sure how you missed this as this comes by default when you have multiple vlans for multiple ssids.
interface FastEthernet0.20
encapsulation dot1Q 20 native
no ip route-cache
bridge-group 20
no bridge-group 20 source-learning
bridge-group 20 spanning-disabled
interface FastEthernet0.60
encapsulation dot1Q 60
no ip route-cache
bridge-group 60
no bridge-group 60 source-learning
bridge-group 60 spanning-disabled
Hope this helps.

Configure Enterprise Manager with multiple Listener

Configure Enterprise Manager with multiple Listener
I have created 2 listeners and connected my database with both the listeners. If I stop one listener then it automatically uses second listener vice versa. But facing problem in case of enterprise manager. If i stop first listener which is on 1521 port it is not connecting to another listener which is on 1522 port.
any help ?

Your potential problem is Enterprise Manager simply doesn't KNOW about that second listener. You can easily verify that when you look at the monitored targets.
Enterprise Manager also reconstructs automagically it's own tnsnames.ora! So, it doesn't connect to second -completely redundant and useless - listener, because the tnsnames.ora entry on the Management Sever is incorrect.
Simply because you didn't made sure OEM could discover the second -completely redundant and useless- listener.
I notice you apparently don't want to read documentation. Yet the only way to work successfully with Oracle, and to become independent, is to read that documention.
Apart from that you should be able to find agentca.bat on your OS with one command, so, yes, I pointed you to the documentation, yes, you can find agentca.bat.
