Load Balancing for Payroll

Hello all,
We have a Production system with a powerful central instance that we use for day-to-day jobs and users, and then a VM (dialog instance) that we have recently added to act as a instance for payroll users to run their long running processes on.
I would like to know if there is a way to reserve access to the new VM (dialog instance) to specific users, or only to specific jobs, as either of these solutions would be good. The only consideration is that the Payroll lady runs these jobs in the FOREGROUND (I know, strange) and she won't do it any other way. So these user/job filters have to work for DIA jobs, not only BGD jobs.
Does anyone have a good idea?
Thanks in advance.

Dear Johan,
As mentioned in the prior response, you need to configure Logon Load Balancing on the CI to effectively use the DI for load balancing.
To restrict access for users to the new DI, you can try to use the method of maintaining the profile parameter in the CI login/password_logon_usergroup, and mention a user group for the users whom you don't mention to login through the CI.
This provides the facility (when activated) - that users with the mentioned user group in the profile parameter will not be able to password login to the CI.
Further to mention the background jobs running in the CI, while scheduling the same in SM36, we have an option to choose the server on which the job has to be run. You can use this option to schedule the jobs in the DI.
Please reply on your trials.
Thank you
Regards,
Vineeth

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

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

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 .

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.

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.

Does Traffic Manager provide database load balancing for MySQL?

I need two VMs to implement MySQL Cluster in Windows Azure. VMs allow configure endpoint load balance set for Mysql, but I did not find tcp protocol in Traffic Manager. Does it provide this service for database
load balancing?

Hi,
Traffic Manager works on the DNS level and routes traffic between public endpoints that sit behind a common DNS name. So you can't use this for your scenario.
However, You can implement
load balancing for VMs in another way.

What is the alternative of F5 BIG-IP LTM Load Balancer for OEM 12c

We want to implement service load balance, however oracle recommended
F5 BIG-IP LTM Load Balancer for OEM 12c
How much it is cost? and is there any free alternative we can use which supported by Oracle?
Thanks

Apart from F5, Cisco is another SLB vendor. I am not sure about any free alternative though.
Note that regardless what SLB that you pick, it should meet the requirements documented in section 29.3.2.2 of the EM12c Release 3 Administrator's Guide:
The SLB must provide support for multiple virtual server ports. Enterprise Manager typically requires that up to 4 ports are configured on the SLB (Secure Upload, Agent Registration, Secure Console, Unsecure Console)
Support for persistence. HTTP and HTTPS traffic between the browser and the OMS requires persistence
Support for application monitoring. The SLB must be capable of monitoring the health of the OMSs and detecting failures, so that requests will not be routed to OMSs that are not availa

ISE 1.2 - Multiple NICs/Load Balancing for DHCP Probe

Hello guys
Just prepping an ISE 1.2 patch 8 setup in our organization. I am going for the virtual appliances with multiple NICs. It will be a distributed deployment with 4 x PSNs behind a load balancer and there is no requirement for wireless or guest user at the moment. I've got 2 points I will like to get some guidance on:
Our DC has a dedicated mgmt network and I plan to IP the gig0 interface of the PANs, MNTs and PSNs from this subnet. All device admin, clustering, config replication, etc will be over this interface. However, RADIUS/probe/other user traffic to the ISE PSNs will be over the gig1 interface which will be addressed from another L3 network. Is this a supported configuration in ISE?
I intend to use the DHCP probe as part of device profiling and will ideally like to have just an additional ip helper to add to our switch SVI config. Also, it will appear that WLCs can only be configured for 2 DHCP servers for a given network so another consideration for when we bringing our WLAN in scope. We however use ACE load balancers within our DC and from what I have read, they do not support DHCP load balancing. Are there any workarounds to using the DHCP probe with multiple PSNs without having to add each node as an ip helper/DHCP server on the NADs?
Thanks in advance
Sayre

Hello Sayre-
For Question #1:
Management is restricted to GigabitEthernet 0 and that cannot be changed so you should be good there
You can configure Radius and Profiling to be enabled on other interfaces
Even though you are not using guest services yet, you can dedicate an interface just for that. As a result, you can separate guest traffic completely from your production network
Take a look at this link for more info:
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/installation_guide/ise_ig/ise_app_c-ports.html
For Question #2
If you are using a Cisco WLC and running code 7.4 and newer you don't need to mess with the IP helper configurations.
The controller can be configured to act as a collector for client profiling and interact with the DHCP thread along with the RADIUS accounting task that is running on the controller. The controller receives a copy of the DHCP request packet sent from the DHCP thread and parses the DHCP packet for two options:
–Option 12—HostName of the client
–Option 60—The Vendor Class Identifier
After this information is gathered from the DHCP_REQUEST packet, a message is formed by the controller with these option fields and is sent to the RADIUS accounting thread, which is in turn transmitted to the ISE in the form of an interim accounting message.
Both DHCP and HTTP profiling settings are located under the "Advanced" configuration tab in the WLC
On the other hand, you can also use Anycast for profiling. You can check out some of Cisco Live's sessions for more info on that. Here is one that is from a couple of years (There are more recent ones that are available as well):

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,

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

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

Server load balancing for application access using multiple servers

1.what are the methods supported by cisco switches for load balancing
2. I want to achive users to access 1 particular ip from different locations but phsically few servers which handle the application and data

well some servers allow you to install routing protocols on them. you could OSPF some links together.
or you could NLB if it is a microsoft server. this uses a heartbeat network, a virtual mac and an IP address bound to the vmac.
you could use NIC teaming. broadcom nics on dell servers allow you to configure them for loadbalancing, failover and a few other options.
or if the servers are mirrored using MSCS or something similar (i.e configured the same but independant) you could just load balance using DNS.
hope this helps. jsut some ideas quickly off the top of my head

Load Balancing for Oracle Release 11i

Hi there,
I am trying to find some recommendations on the need for load balancing in the middle tier for a 3 tier Oracle Release 11i implementation. Here are the questions that I have.
1. Is load balancing very common for a 11i implementation ?
2. What are the probable issues that one might encounter if there is no load balancing ?
3. If there is load balancing how many servers are generally used for the same ?
4. Do we only install Forms server on multiple servers or we install WebDB and Apache on all the servers ?
5. Is it true that Web servers are the most likely to be down and thus mandating the use of load balancing ? If that is true, would it be prudent to install Web Server and Form Server on each server m/c and in the process having redundant servers ?
Let me know your thoughts.
Thanks,

Adapter Engine Load balancing for Messages HTTP SOA/SOE

Greetings all,
We are currently implementing our SOE/SOA solution utilizing SAP services between a .Net Application. Basically .Net -> PI -> ECC and back.
We are load testing the system and are now experiencing the CI getting overloaded.
We have upped the Thread Count (Thread Manager 350 and System Threads 120) and the Queue thread from 5 to 20.
We are using SOAP with Principal Propagation.
There is a hardware load balancer we are using which can spread the load between multiple application servers. We modified the SLDRegistration host and ports (http/https) in Visual Administrator (SAP XI AF CPA Cache) in the global server node.
In SXI_CACHE Got -> Adapter Engine Cache, it displays http://<sidms>:<port>/MessagingSystem/receive/AFW/XI
Is this where the load balancer should be placed with the port name?
Any help would be appreciated.
Thanks
