Send Email issue using "Mail Server Load balancer" (Cisco ACE 20)
I have asked this question in SAP MII forum too but it appears issue could be in NetWeaver Mail API. Please let me know if someone have experienced this kind of issue or any suggestions.
The send email action was working file in MII with smtp mail server on port 25. Recently basis did a change in mail server ip address and they installed a new Load Balancer . The Load balancer is between SMTP and MII. After this change MII does not send email (unknown source error). now MII send email action has ip address or qualified path of Load balancer in MII send email configuration instead of direct ip address of SMTP server. Below is the error message in Net Weaver logs.
MII still sends email if direct ip address of email server provided instead of Email Load balancer but not through Load balancer .
Any suggestions ?

I don't have experience with Blackberry, but, as the document mentions, the first thing to do would be making sure that the connection timeout is set to something high enough
You can find more details on how to modify this value at the link below:

App.server load balancing for SAP System with 1 PS
Hi,
In SAP CPS 7.0 (Build M26.12) I have a SAP system with Central Instance + 10 App.servers, but all instances are managed by 1 ProcessServer.
After activating the "App.server load balancing" setting in SAP system definition the application servers are becoming visible in CPS with their load factors (number of BGD wp's on app.servers) and load numbers (number of active jobs on app.servers).
This is so far fine, but the additional functionality is not working as I would expect, I have issues with 2 functionalities:
1. Based on documentation after activating also the XAL connection the CPS should submit the job on app.server with best performance based on XAL monitoring data filling the TARGET_SERVER parameter.
This functionality is not working for me at all
2. A useful functionality after activating the "App.server load balancing" setting is that the ProcessServer is going to "Overloaded" status when all BGD wp's of SAP system are occupied, thus restricting submitting new jobs during overload situation. But I had an issue also with this functionality, after SAP system recovery from overload situation, the CPS still remained in Overload status (so no new jobs were submitted).
As a workaround I had increased the treshold values for loads on all app.servers for this SAP system, what was fine for several days, but after a while I believe this was a reason of unexpected performance issues in CPS, therefore I have deactivated the 'App.server load balancing" setting at all for this ProcessServer.
I would appreciate your feedbacks with this functionality.
Thanks and Regards,
Ernest LiczkiHi Preetish,
This connect string option is to loadbalance RFC connections. These are balanced upon login, once you are connected to a particular application server (AS) you stay on that server until you reconnect.
Since CPS uses multiple RFC connections, this will result in the connections being distributed over the available AS resources which is fine as long as they are generally evenly loaded. If you have certain AS hosts that are continuosly more loaded than the rest, then you probably don't want the CPS RFC connections to end up on these servers.
The original question is about loadbalancing of batch jobs over the available AS resources, and this is done independent of the RFC connection load balancing. Even if all CPS RFC connections are pinned to the DB/CI host, you can still loadbalance jobs over the available SAP AS hosts, either by using SAPs builtin balancing, or the CPS algorithm by activating the checkbox as indicated in the first entry in this thread.
Finally, to reply to Ernest's question: I believe there are some fixes on the app load balancing in the latest release, M26.17 should be available on the SWDC now.
Regards,
Anton.

Hi
I try to install Load Balancing with Dev6/Patch2 and OAS4.0.7.1
on 4 Machines with WinNT Server 4 SP 5. I tried to do it as
described in the documentation. But I did not succeed. It seems
to be that the Doc is not complete or wrong. Could somebody give
an example how to set up the LB Servers and Clients as NT
Services ?
Thank's in advance

nullHi Steven,
No LACP and SLB are different.
LACP is the Link Aggregation Control Protocol, which is the protocol used within the IEEE 802.3ad (now 802.1AX) Link Aggregation mechanism to control the bundling and unbundling of the physical links into an aggregate link.
Server Load Balancing is a feature in IOS to load balance traffic destined to a virtual IP across a group of real IP. From Configuring Server Load Balancing:
The SLB feature is a Cisco IOS-based solution that provides IP server load balancing. Using the IOS SLB feature, the network administrator defines a virtual server that represents a group of real servers in a cluster of network servers known as a server farm.
Server Load Balancing is effectively what the Cisco Application Control Engine (ACE) etc., does but in IOS.
Regards -
the servers are loadbalancing between the switches '3'
and '2' and the link between the two switches is blocked.
This link was forwarding before and thus any traffic going to the server was
send to the Servers correctly no matter on which switch they are active.
However after addition of another link in between the switches 'root'
and '1', the path cost to the root has decreased and thus the link
between the '2' and '3' is Blocking and the other link between
the '2' and '1' is Forwarding as it should be ideally. But
this would be creating an issue because the trafic coming from outside i.e.
through switch '1' to the server will be correctly send to the
server if the server NIC is active on the '3' because the Virtual MAC
addresses are binded accordinlgy. In case the server falls onto the other
NIC which is on the '2' the traffic won't be able to pass because the
MAC address is not binded on the trunk connecting the switches '1'
and '2'. This binding cannot be done because the same MAC address is
being learned on the another trunk on the '1' which is connecting
to 'root'. So if we bind the same Virtual MAC on two trunks on the same
switch ('1') then this will cause MAC Address Flapping on the
switch and hence canot be done.
In another case,we can able to bind virtuak MAC on two trunks on the same
switch('1') and it's working fine.
The servers are load balancing in round robin fashion. each server has 2 NICs and work in Active-Passive mode. The servers load balance each other when all their active links are connected to '3' switch but when two of the active NICs of two servers are connected to '3' and the rest of the two active NICs from the other two servers are connected to '2' switch then only the forst 2 servers load balance and the other 2 servers do not load balance.
Please help.
Thanks in advance.In my experience, server load balancing is one of the most difficult things to get going properly in a switched LAN environment. Switched LANs are designed so that one MAC address can only be bound to one switch port. Therefore, if you have two NICs with the same MAC address (real or virtual), then you will get flapping somewhere.
I have seen various ways that the manufacturers try to get around this limitation of switched LANs. For example, one technique I have seen, practiced by ISA Server, is to use a multicast MAC address for the service so that frames go to both exit ports. But that does not always work well unless you tweak the network to acommodate it.
What sort of servers are they, and what system is used for the load balancing?

WLC Radius Server Load Balance
Hi,
Can someone provide me detailed description on how WLC Radius Server Load balance works.
Becuase, I encounted a problem of User Authenticated with the 1st Radius Server, but Accounting Records are actually on 2nd Server .
Any response will be very appreciated
-AngelaHi Angela,
I pasted below the part of config guide explaining the different modes. In summary :
-Fallback off means : when 1st radius server shows dead , WLC moves to the second. And will only change again when the 2nd is dead too.
-Passive means : whent 1st radius is dead, WLC moves to the second. If there is a new authentication coming in, it will try the 1st radius server again
-Active means : WLC constantly sends radius probes to detect when primary is back up.
config radius fallback-test mode {off | passive | active}
where
•off disables RADIUS server fallback.
•passive causes the controller to revert to a server with a lower priority from the available backup servers without using extraneous probe messages. The controller simply ignores all inactive servers for a time period and retries later when a RADIUS message needs to be sent.
•active causes the controller to revert to a server with a lower priority from the available backup servers by using RADIUS probe messages to proactively determine whether a server that has been marked inactive is back online. The controller simply ignores all inactive servers for all active RADIUS requests. Once the primary server receives a response from the recovered ACS server, the active fallback RADIUS server no longer sends probe messages to the server requesting the active probe authentication. -
Using ACE for proxy server load balancing
Hello groups,
I wanted to know your experiences of using ACE for proxy server load balancing.
I want to load balance to a pool of proxy servers. Note: load-balancing should be based on the HTTP URL (i can't use source or dest. ip address) so that
a certain domain always gets "cached/forwarded" to the same proxy server. I don't really want to put matching
criteria in the configuration (such as /a* to S1, /b* to S2, /c* to S3,etc..), but have this hash calculated automatically.
Can the ACE compute its own hash based on the number of "online" proxy servers ? ie. when 4 servers are online, distribute domains between 1,2,3,4 evenly.
Should server 4 fail, recalculate hash so that the load of S4 gets distributed across the other 3 evenly. Also load-balancing domains of S1 ,S2 and S3 should not change if S4 fails.....
regards,
GeertThis is done with the following predictor command:
Scimitar1/Admin# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Scimitar1/Admin(config)# serverfarm Proxy
Scimitar1/Admin(config-sfarm-host)# predictor hash ?
address Configure 'hash address' Predictor algorithms
content Configure 'hash http content' Predictor algorithms
cookie Configure 'hash cookie' Predictor algorithms
header Configure 'hash header' Predictor algorithm
layer4-payload Configure 'hash layer4-payload' Predictor algorithms
url Configure 'hash url' Predictor algorithm
Scimitar1/Admin(config-sfarm-host)# predictor hash url
It does hash the url and the result takes into account the number of active proxies dynamically.
This command has been designed for this kind of scenario that you describe.

CSM(content switching module) supports the 2 tier server load balance ?
hi everyone,
Does any know the CSM support 2 tier server load balance ?
this means that CSM perform the server load balance for servers and the same servers require another time Server load balance. In the other word,
the CSM supports server port and client port for server load balance ?
thanks
fred.Hi, this seems to describe a typical case of multi-tier design where the CSM needs to handle 2 types of connections:
1. clients->CSM->serverfarm1
2. serverfarm1->CSM->serverfarm2
We usually refer to the second type of connections as server-to-server load balanced traffic.
There is no problem in handling that scenario with the CSM and you have a few options.
In particular, each virtual server on the CSM can be configured to only accept incoming connections from a specific VLAN, so you can use that as an additional security measure or to distinguish connections based on which VLAN they come in from.
If you want to, you could even configure the CSM with 2 virtual servers with the same exact virtual IP and L4 port, but listening on 2 separate VLANs (the client-side VLAN and serverfarm1 VLAN) and use a different server farm based on that.
One important thing to keep in mind when handling server-to-server load balanced connections: if serverfarm1 and serverfarm2 are on the same VLAN, you have to configure "client NAT" for the server-to-server connections, to force the return traffic back to the CSM. -
Web Proxy Server Load Balancing
I deployed Sun Jave Web Proxy Server 4.0 as a Reverse Proxy. I would also like to use it as a load balancer. As per the instructions, I configured the obj.conf file as shown below
Route fn="set-origin-server" server="https://xx.xx.xx.xx" server="https:yy.yy.yy.yy" sticky-cookie="JSESSIONID" sticky-param="jsessionid" route-hdr="Proxy-jroute" route-cookie="JROUTE" rewrite-host="true" rewrite-location="true" rewrite-content-location="true"
But, it is not doing load balancing. It always sends to the first server (xx.xx.xx.xx). I guess that is because I used mapping as follows:
NameTrans fn="reverse-map" from="https:xx.xx.xx.xx" to="https://server.net" rewrite-location="true" rewrite-content-location="true"
NameTrans fn="redirect" from="http://server" url="https://xx.xx.xx.xx"
NameTrans fn="map" from="https://server" to="https://xx.xx.xx.xx" rewrite-host="true" name="pa-server-farm1" NameTrans fn="map" from="/" to="https://xx.xx.xx.xx" rewrite-host="true" name="pa-server-farm1"PathCheck fn="url-check"ObjectType fn="block-ip"
ObjectType fn="cache-enable" cache-auth="1" cache-https="1" query-maxlen="0" min-size="0" Service fn="proxy-retrieve"
I don't understand how routing and mapping work togother. Any help in this regard is appreciated.Motor,
the following is from the Web Proxy Sever Administration guide. Please, check the last paragraph for the explanation. Any how, the problem is simple. I am using the Proxy Server as the Reverse proxy. And at the same time, I would like to use two origin servers (for load balancing) instead of one. How do I make both load balancing and reverse proxy functions work together?
Thanks
To Create Regular or Reverse Mapping
Access the Server Manager, and click the URLs tab.
Click the Create Mapping link.
The Create Mapping page is displayed.
In the page that appears, provide the source prefix and source destination for the regular mapping,
for example,
Source prefix: http://proxy.site.com
Source destination: http://http.site.com/
Click OK.
Return to the page and create the reverse mapping, for example,
Reverse mapping:
Source prefix: http://http.site.com/
Source destination: http://proxy.site.com/
To make the change, click OK.
Once you click the OK button, the proxy server adds one or more additional mappings. To see the mappings, click the lView/Edit Mappings link. Additional mappings would be in the following format:
from: /
to: http://http.site.com/
These additional automatic mappings are for users who connect to the reverse proxy as a normal server. The first mapping is to catch users connecting to the reverse proxy as a regular proxy. The �/� mapping is added only if the user doesn't change the contents of the Map Source Prefix text box provided automatically by the Administration GUI. Depending on the setup, usually the second mapping is the only one required, but the extra mapping does not cause problems in the proxy. -

Server Load Balance in one network using CSM Cat6509
I have 2 Web Servers with real IP address 10.1.12.61 and 10.1.12.62 (subnet mask 255.255.255.0). The virtual IP address configured on CSM is 10.1.12.100
I also have 2 Application Servers with real IP address 10.1.12.81 and 10.1.12.82 (subnet mask 255.255.255.0). The virtual IP address is 10.1.12.120.
Users will access Web server using the virtual IP address (10.1.12.100) so that the traffic will be load balanced.
But there is also requirement that those Web Servers access Application Servers using IP address 10.1.12.120 so that the traffic will be load balanced as well.
Is this requirement feasible?
Can CSM load balance between servers in one network address?Budiman,
I am building the same situatiuon here. But the most simple part seems not to be working. I have two webservers in the same subnet as my VIP.
The clients can be everywhere in every subnet.
This is what happens:
btpebgw70#sh mod contentSwitchingModule 9 conns
prot vlan source destination state
In TCP 401 192.6.53.42:1901 151.183.58.196:80 ESTAB
Out TCP 401 151.183.58.196:80 192.6.53.42:1901 ESTAB
ok this is good but:
btpebgw70#sh mod contentSwitchingModule 9 reals detail
151.183.58.201, ORBIS, state = OPERATIONAL
conns = 0, maxconns = 4294967295, minconns = 0
weight = 8, weight(admin) = 8, metric = 0, remainder = 0
total conns established = 58, total conn failures = 58
the failures have the same value as the established. Can you send me your config part of the csm because I am getting tired of this. Please email to [email protected]
Thanks in advance! -
Virtual BizTalk Server load balancing
We in process migrating Physical Biztalk server from current datacenter to a cloud based datacenter.
The requirement is the all server deployed that must be ritualized.We are using Citrix load balancer in the new datacenter and VMware 5.1 as host OS.
we were not successful deploying the load balancing with NLB and Software LB within the virtual world.
Please HelpSeeing that you have an external load balancer available, you really should not be trying software load balancing. Windows NLBS is a software based load balancing and is not really dependent on the physical/virtual hosting of the OS. There are certain gotchas
w.r.t the NLB modes since they depend on network protocols such as arp, propagation of MAC addresses and usage of the MAC in the L2 routing tables of network devices.
You should be taking the help of the cloud service provider as ONLY they would have an understanding of their underlying networking infrastructure such as VLANS. addressing, routing rules and such.
You could also refer to the VMware support forum for KB's such as
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006580
Most importantly, NLBS is a base OS related service and you're more likely to get a response in the Windows Server Forum. In the specific case of BizTalk, the Windows NLB is only used for hosting the out of process services such as those associated with
HTTP/s Receive, orchestration published as schemas, web services (asmx) and/or WCF endpoints.

App-V 5 Publishing Server + Load Balancing (NetScaler) issue
All,
I have attempted to load balance my App-V 5.0 deployment, which includes two nodes (appv-1 and appv-2) on a Citrix NetScaler VPX appliance.
The management server is working fine, when browsing to the load balanced VIP DNS alias - pass-through authentication works great and the management console is displayed.
When I attempt to browse to the load balanced VIP DNS alias for the Publishing Server, it prompts for authentication credentials, then displays the following error:
Method not allowed. Please see the service help page for constructing valid requests to the service.
When I attempt to browse using the same internet explorer instance to http://appv-1.fqdn:8088 it displays the XML page after entering authentication credentials.
Here is my set-up & what I have done....
Appv-1 Server
Management Server installed on Port:8088
Publishing Server installed on Port:8090
SQL Cluster and Mirroring configured (tested and working)
Appv-2 Server
Management Server installed on Port:8088
Publishing Server installed on Port:8090
SQL Cluster and Mirroring configured (tested and working)
NetScaler
Management VIP: 10.1.1.148
Publishing VIP: 10.1.1.124
Both Appv-1 and Appv-2 are setup as services and bound to the corresponding Virtual Servers.
Load balance alogrith - persistence - source IP: 255.255.255.255 - Least Connection
DNS and AD Modifications
host A record - appvmgmtsrv.fqdn = 10.1.1.148
host A record - appvpubsrv.fqdn = 10.1.1.124
computer object create in same domain for appvmgmtsrv and appvpubsrv
SPN Modifications:
setspn –A http/appvmgmtsrv:8088 domain\appvmgmtsrv
setspn –A http/appvpubsrv:8089 domain\appvpubsrv
setspn –A http/appvmgmtsrv.domain.local:8088 domain\appvmgmtsrv
setspn –A http/appvpubsrv.domain.local:8090 domain\appvpubsrv
IIS Modifications:
Appv-1 and Appv-2 - ApplicationHost.config - modified with below line for both Management and Publishing Server sections:
<windowsAuthentication enabled="true" useKernelMode="true" useAppPoolCredentials="true" />
Rebooted and IIS starts correctly.
Testing
On Appv-1 if I browse to http://appvmgmtsrv.fqdn:8088/console.html it asks for authentication, when authentication is entered it fails.
On another other machine in the environment if I browse to http://appvmgmtsrv.fqdn:8088/console.html it automatically loads the console with the credentials of the logged on user.
Launching the Management Console via Load Balanced DNS name works on every other server except itself.... assume this is Kerberos modifications? (This only happens when I disable the appv-2 node on the load balancer, forcing all IIS connections to Appv-1).
The management server issue above is not a big one and can work around that easily. The major issue is with the Publishing Server. .. .
On Appv-2 if I browse to http://appvpubsrv.fqdn:8090 it will prompt for authentication, once enter it displays: Method not allowed. Please see the service help page for constructing valid requests to the service.
in a new tab if I enter http://appv-1.fqdn:8090 it will prompt for authentication, once enter its displays the XML page with App-V meta-data.
Can anyone shed some light on this issue please.... When I update the App-V client with the load balanced publishing server VIP DNS it displays the following error in the event log:
Getting server publishing data failed.
URL: http://appvpubsrv.fqdn:8090
Error code: 0x45500D27 - 0x80190195
Any help will be greatly appreciated. ....You could read

Biztalk: Server load balancing
Hi,
We have 2 biztalk servers in the group. For past few days CPU usage on one server was comparatively very high as compared to other. First server was showing around 60% of CPU usage while second one was reporting 12 %.
Today I just started to stop every host instance on the first server in order to find out the process resulting in high |CPU usage. It came to BizApp.. Host assigned for processing orchestrations.
At first I could'nt understand the reason why first server was taking all the load while second one wsa comparatively free. But to my surprise once I restarted the host instance on first server, CPU usage dropped to 8% for the first one.
I could not understand the reason behind this? It would be really helpful if anybody can give me a clue about it.
Thanks in advance.ShadyHi Shady,
How is your environment set up? I assume you have multiple hosts setup for receiving, sending and processing. Hosts running the receive handler for the HTTP,
SOAP, and BizTalk Message Queuing (MSMQT) adapters require a load-balancing mechanism such as Network Load Balancing (NLB) to provide high availability. Host cluster support is provided to support high availability for integrated BizTalk adapters that should not be run in multiple host instances simultaneously; such as the FTP receive handler or, under certain circumstances, the POP3 receive handler (http://msdn.microsoft.com/en-us/library/aa560059(BTS.20).aspx). Everything else just do not require any additional clustering or load-balancing mechanism because BizTalk Server automatically distributes workload across multiple computers through host instances, unless you have made changes to hosts themselves (throttling) (http://msdn.microsoft.com/en-us/library/aa559893(BTS.20).aspx).

BizTalk Server -
Hi,
Currently I'm working on a simple electronic newspaper application. In this application, after login, users can download articles from a digital newspaper. The client application sends content requests to a server-side component in order to retrieve the article.
In order to have a scalable infrastructure, the server-side of this application is implemented using the multi-server paradigm.
Our application has to have some very basic load balancing between the servers:
- the total amount of downloaded bytes over a pre-defined time T has to be calculated for each server.
- if this value exceeds by 10% the average value for all servers, the request has to be redirected to another server. In this case, the client gets a reference to another (less loaded) server.
In order to load balance the servers, the number of downloaded bytes over a given period should be tracked, and communicated within the server pool.
My question is, how can this be implemented using standard Session Beans ? Do I have to use stateless or stateful session beans ?
Does somebody have some ideas about the design of this application concerning the load balancing functionality ?
Thanks !

I want to clerify one thing that,
whether you want to
the number of downloaded bytes over a given period should be tracked? and communicated within the server pool with the session beans or what?
