SAP BO 4.0 load balancing

[former_member185239]

Hi,

We want to implement load balancing in SAP Business Objects 4.0 sp4. Coming across load balancing part there are different ways to achieve it:

-Hardware level load balancing

-BO Cluster install for load balancing through CMS.

-Web-tier Tomcat load balancing.

Can anyone please suggest advantages of implementing Hardware level load balancing VS BO cluster method?

Hi Ashutosh,

Take a look at following resources:

Configuring the load balancer - Business Intelligence (BusinessObjects) - SCN Wiki

Hope this info helps.

Onkar,

Sometime  back in our development we had BO Clustered 4.0 installation. 1st node was installed with bundled tomcat & sybase anywhere db. Whereas 2nd node was installed with 'Expand' option using ODBC connection pointing to sybase anywhere db. (No additiohnal tomcat web-tier) was installed. As per SAP guides by default in this scenario load balancing is in place through CMS. Can you brief on advantages of hardware load balancing VS default load balancing in clustered environment?

With Regards

Hi,

You can setup the clustered/load balancing  on each BO tier.In your scenario you have setup the load balancing/failover on the CMS level only.But the same time you can setup the load balancing on webi tier or on processing tier also (multiple web tier and multiple webi,crystal services).

You need hardware load balancing  once you will setup the multiple web tier connecting to same CMS.Like F5 load balance one type of load balancer which balance the load between two  web tiers.

Hi Ashutosh ,

CMS  load balancing ( Clustered  CMS) will load balance the request coming to  BI platform between 2 or more CMS. This is taken care internally by CMS. It is suggested to have CMS machine on separate hosts. As Prateek said , hardware level load balancing will allow you to split network load across multiple servers , this can be implemented in the Webtier . .i.e. multiple appserver    to handle the http request to from the user access the BI platform ( via BI launchpad , CMC...) via the hardware load balancer like BIG -ip.

Also you can have multiple webi servers to load balance the users for webi reports.

HI Ashutosh

Hardware load balacing is a technique that is used to split network load across multiple servers by using some applicance.

The basic principle is that network traffic is sent to a shared IP in many cases

called a virtual IP (VIP), or listening IP.

This VIP is an address that it attached to the load balancer. Once the load

balancer receives a request on this VIP it will need to make a decision on where

to send it.
