CSS Load balancing for Exchange Server

Hi,
I have CSS configured in single arm and I have multiple servers configured for load balancing and it is working fine but when I am configuring Exchange server for load balancing I am facing problem and applications and printer/scanners are not able to send the email through the Virtual IP address configured for exchaneg server.
But if we configured the real server IP in the printer/scanners they are able to send the email. While checking the logs on the exchange server, it is showing that request for the email so coming from the Exchange VIP configured in the CSS.
I can telnet on port 25 on the VIP address (192.168.200.237). But unable to send the email through this VIP.
Below is the configuration
service ENOC_EXCHANGE-1
ip address 192.168.200.235
active
service ENOC_EXCHANGE-2
ip address 192.168.200.236
active
content EXCHANGE
    add service ENOC_EXCHANGE-2
    add service ENOC_EXCHANGE-1
    vip address 192.168.200.237
    active
group EXCHANGE
add destination service ENOC_EXCHANGE-1
add destination service ENOC_EXCHANGE-2
vip address 192.168.200.237
active
DC-CSS01# show rule GIT EXCHANGE
Name:                EXCHANGE   Owner:                ENOC_GIT

Url:
Redirect: ""
TCP RST client if service unreachable: Disabled
Rule Services & Weights:
1: EXCHANGE-1-Alive, S-1
2: EXCHANGE-2-Down, S-1
=============================================================================
Please let me know how to solve this problem. System team is saying with the physical IP address it is working fine problem with Load balancing. I have even tried with the
Add service command in the group but didnt work for me. If i will remove the group command then I cant telnet on port 25.
I think this is related to single arm modle or some wrong configuration for the NAT.
Kindly assist me

Hi
Printers are on Vlan 80 ( gw is 192.168.80.1) and exange server is on vlan 200 (gw is 192.168.200.1) i have multiple vlan which will communcate with exchange.
I hv other servers on 200 subnet which are working fine in load balancing.

CSS Load Balancing with Billing Server

Hi Gilles
Could I have a CSS load balancing two servers and also have it communicate with a billing server across the network. If yes then how can I do it?
Regards,
Sushil

the CSS does not have the notion of billing server. A separate device - like the CSG - should be used if you need to collect billing info.

HA and Load Balancing in Exchange Server 2010

Hi
My office just have 2 servers Exchange Standard 2010 (Licensed). I installed 3 roles on 2 servers (called Ex1 & Ex2). I configured Windows NLB for Hub Transport and Client Access. That 's fine.
But the maibox is seperated each server. Ex1 is main mailbox, so when Ex1 down, mailbox database will down too.
I 've read DAG solution but I just have 2 servers and it 's running WNLB. My office not enough cost to buy Hardware Load Balancer.
Does anyone have a solution for my problem ?
Thank you

Hi,
If you want to use DNS round robin, it is recommended to lower the TTL values of DNS records to 5 minutes.
DNS Round Robin has no automatic server failure detection. If a host goes down, Administrator will need to realize it, remove the DNS Record for the server that went down, and then clients will have to wait for the TTL value on the old DNS record to
expire.
Here is an article about DNS round robin for your reference.

CSS Load Balancing Citrix Terminal server, is ti possible ?

Hi we have to balance a Terminal Server Citrix Server Farm with css, did anyone already realize it? Is there any problem to do it ? Someone told me there is nat problem with citrix metaframe terminal server, has anyone information about it ?
Any help will be greatly appreciated. Many thanks

Stickyness means that once a user is directed to a server through the load balancer, that user will remain on the server he was first load balanced to for the duration of their connection. Otherwise, every tcp connection that a user makes is load balanced to whatever servers are configured. There are severalways to configure stickyness. You can do it via:
-source IP
-source IP and destination port
-text string in a cookie or URL
-SSL session ID
take a look at this document that explains it better than I could:

Issue in setting Load balancing for Indesign Server CS5.5

Hi All,
I need to set up load balancing mechanism for Indesign Server CS5.5 on Windows Server 2008 R2(64 bit version).
I have dutifully following all steps defined in "WORKING WITH LOAD BALANCING AND QUEUEING FOR ADOBE INDESIGN CS5 SERVER.pdf"
After running Indesign server using batch file "startup-indesign-server-CORBA-4instances.bat" from "<ID_SDK>\samples\load-balancing-and-queuing-clients\indesignserver-startup-scripts", I get only one instance of Indesign Server running. How to run multiple instances of the INDD server ? Is running multiple instance has something to do with type of licensing ?
Now I run Clover.cmd script, I get this screen. I have no idea why its not working. Please help. Please let me know, if the scenario is not clear and more information is required.
Thnx,
D

CSS Load Balancing for MS Winsock Proxy Client

Has anyone load balanced Microsoft Winsock Proxy client? I am trying to load balance internal users using the Winsock client to two MS ISA Servers running Winsock proxy for application access to the internet.

Thanks for the post, I got this from Microsoft:
I wanted to update you on the information I investigated on the firewall client. I found the the actual port connection used to control the connection thru ISA is by default UDP. This UDP session is over 1745 to the ISA server. This intial connection then allows for a connection over an ephemeral port to the ISA server for the actual data transfer. The data transfer is done via a TCP connection. The connection control is UDP based by default. This can be changed in the Wspcfg.ini file. By adding the ControlChannel value to the WSP_client_app section of this file, you can use WSP.TCP to allow the connections to be based with TCP. In your situation, this may be the best scenario due to the connections being load balanced.
TCP is used by default when checking the Firewall configuration. This is why the traces showed the connection with TCP.
Information on this can be found in the ISA help files. In the search panel of the ISA help, type in "ControlChannel" without the quotes and it will show information on this feature.
I will re-test with TCP only setup, and see if this helps. I also have some sniffer traces I need to review to see if maybe NAT is killing me, not UDP traffic.
I'll post back my findings next week.

Problem with WLIOTimeoutSecs in weblogic and apche CSS load balancer

Hi,
We are using Weblogic 11g, apache 2.2 and CSS load balancer for load balancing.
we have huge reports which take minutes to generate and hence we need higher value for WLIOTimeoutSecs. This works fine when we use server url but WLIOTimeoutSecs is not working when we use CSS load balancer.
We checked with our load balancing team they said CSS load balancer will not repost the request.
Here is the plugin configuration
<Location /*****>
SetHandler weblogic-handler
PathTrim /
WebLogicHost 'serevrip'
WebLogicPort 'port'
WLIOTimeoutSecs 3600
Idempotent OFF
WLProxySSL ON
DefaultFileName /***/***/index.jsp
Debug On
WLLogFile /***/***/***/***.log
</Location>
Could some please help me on this.
Thanks in advance
Regards,
Venkat

Hi Tarun,
The problem occurs when the SSL is enabled on apache. If I access the same URL over HTTP, the parameter WLIOTimeOut works fine.
Also I observed that, none of the parameters are getting applied to the plugin. I had switched on 'DebugConfigInfo'. With this the HTTP URL with ?__WebLogicBridgeConfig as query parameter returned the complete configuration. However when accessed with HTTPS the server did not return the configuration.
Is there a specific configuration to be applied when apache is used with SSL?
Thanks for your help,
Shashi

Load Balancing for Microsoft Orchestrator application

Hi Folks,
We are trying to configure Load Balancing for Orchestrator Server.
We have closely 200 users running a workflow.. so in that case, we need to configure the Runbook Server as a application load balancing cluster, so please do share me the configuration guides..
Regards,
Venu
Best regards, Venu.

I'm in the middle of doing this right now. There is a doc on metalink (233428.1) that details the process. I would highly recommend trying this in dev/test env first. Even though the instructions are very straight forward and not very complicated, I'm still having configuration issues.

Installing 2 Application server and 1 DB server and load balancing for 11i

Hi,
I need info on how to install and configure load balancing for 11.5.8 on Win2000. The scenario: 1 db server DB, 2 apps/web/forms servers AP1 and AP2. Using rapid install you can only specify one db server A and one form server in multi node installations, right? How do I install the form server on AP2? Can I use the same config.txt? The computer name for AP2 is different.
Thanks & Regards,
Jagal

I have the very same issue. We want to install 4 web/form servers on a hardware load-balancer and the issue is we can only specify one forms server.
Does anyone know the secret bullet here?
Thanks

Load balancing 2 DNS server

how to configure the CSS to load balance 2 DNS server ?

first configure the services like this :
service dns1
ip address x.x.x.x
active
service dns2
ip address x.x.x.x
active
Then configure the content rule
owner mycompany
content dns
vip address x.x.x.x
add service dns1
add service dns2
active
Then we need to setup something for the dns answer
group dns
vip address x.x.x.x !!!!! same as for the content rule
add service dns1
add service dns2
portmap disable
The portmap disable requires software 5.03(33) or above.
The command is also in 5.01

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance

Load balancing on RMI Server Application

Hi there, I'd like to know more detail about load balancing on RMI server application, been digging the web for some time, but couldn't find much information, does anyone know any website or has the knowledge of load balancing on RMI to share? Sort like its design and implementation.
Thanks,
Jax

I want performance and fault-tolerance,
In that case, is it necessary to have a main
rmi server to allow client to access and pick one of
the rmi servers for the client?Well, if you have one main RMI server, you have a single point of failure again.. Why can't your application know about all rmi servers, and randomly choose one? If it's down, pick a different one.. If your applicatoin is an applet, you'll have to sign it.. Do that and put it on 2 redundant web servers. You have performance by splitting the load and you have your fault tolerance by having x identical rmi servers.
If you're saying what I think, why would you have one main rmi server that picks a different rmi server? That's more work AND your redundancy goes byebye, ie if your main rmi server dies..

Setting up Load Balancing for 11i for Intranet & Internet Access

Our current environment for 11i (11.5.5) is accessed only internally (via Intranet). We need to allow outside access (via Internet) also for self-service apps (ie. HR). Oracle Support/Metalink has stated that Load Balancing (note 148155.1) is the only supported method to have multiple (Apps Servers) systems access a single database. Could I get feedback from anyone who has implemented Load Balancing for 11i? Additionally if someone has implemented this for both intranet and internet access how has your company setup? Do the secondary server(s) from the Load Balancing note reside in the DMZ? And thus the primary app server and database reside inside the firewall? Thanks....

Hi,
We are using 6 middle tiers for internal access for intranet access and 2 middle tiers in External DMZ with only web server running for Extrenal Access over Internet for Self Service.
You Implement one Load Balancer for first 6 internal Middle Tiers with site level profiles pointing to Internal .
You implement second Load balancer for external 2 middle tiers with server level profile options for these two servers pointing to External Load balancer .

Load balancing for SAP R3 through ITS for EP .

Dear All
We are using ITS bease SAP R3 iviews in EP ..The landscape is as follows
EP --> ITS --> SAP R3 .
We need to configure a load balancing from EP to R3. Currently the ITS is set to hit one Application server on SAP r3 . How do i configure load balancing in EP for R3 .
Even if we use the Load Balancing Iview, it does not prompt to enter SAP R3 Application servers in the EP Load balancing iview properties.
all it asks is the ITS server and SAP server for connectors.
Regards
Jayesh

Please do the following steps to accomplish load balancing. It includes both ITS definition and system definition.
ITS Definition:
System definition alone will not help. Because you are using ITS to access SAP R/3. ITS uses global.srvc file to access SAP R/3 system.
When you install ITS you have option to choose connection with SAP R/3. You have two options here.
1) Message server with load balancing
2) Application server.
If you choose option 1, you will have load balancing on SAP R/3 using ITS.

Network load balancer for Agentry applications

Hi Expert,
I'm going to implement a SAP Mobile Platform solution that will use an agentry application and I need some clarification about the HA configuration and the usage of the network load balancer and relay server. Just for information I'm going to use SMP 2.3 SP4.
My understanding is that Relay server is a reverse proxy and load balancer for SMP but It can't be used for the agentry applications. Is this correct?
Based on the standard configuration in order to balance the load of the client devices in the SMP cluster I have to use a Network load balancer, therefore the technical architecture of my solution should be the following:
|Agentry Client device| ----> | Network Load Balancer | ----> | SMP and Agentry Cluster| -----> |Back end systems|
Is this correct? I didn't find specifications about the Network load balancer.. Is there a list of the Network load balancer products supported from SAP for agentry application. Is there any best practice on the network load balancer?
Thank you in advance for you collaboration.

Because we don't test any directly with our QA we don't have have a preferred products. Talking to our consulting group they normally just use what the customer already has installed in their network. Both Software or hardware load balancers has been used.
The key part needed for the load balancer for Agentry 6.0.x and SMP 2.3 (not SMP 3) that it is set to TCP Pass through.
