Load Balancing OBIEE using OC4J
Hi All,
I would like to know if there is a way of load balancing 2 instances of OBIEE using OC4J.
Please advice if possible and the steps required to achieve that.
A small correction ... we have 2 instance of OBIEE and 2 of stand alone of OC4J
Is there any way we can attempt to load balance the two???

I believe OC4J stand alone can do this but i dont know how
Is there any way we can attempt to load balance the two.

Cluster/load balance weblogic using L4 switch like Alteon
Can I install weblogic as a standalone server on 2 or more server and
cluster/load balance weblogic using a hardware balancer like Alteon Layer4
switch (of course I will use a centralised storage to maintain a single copy
of data which will eliminate syncronizing problem among servers)?
BTW, Alteon can support persistent binding. The reason to use a Layer 4
switch is that it is very fast, and this will make the application server
layer transparent to client, the client can think this is a single server
(it don't need to know whether there are 5 weblogic servers or 20 weblogic
servers behind switch), and hardware are more reliable, sacalable and fast.
I am not sure whether the normal weblogic clustered servers need to
share/exchange info on the running memory, if it does, this approach will
fail.
So My understanding is:
Alteon with WL 6.0 can do load balancing for:
entity bean
stateless session bean
but can't do load balancing for:
stateful session bean (will persistent/sticky binding solve part of the
problem except fail-over)
in-memory replication
am I right?

Load balancing weirdness using NAT and same-metric route
Hi.
I'm trying to set up a double-WAN load-balancing scenario:
I decided to attempt the "multiple same-metric routes with NAT" approach so I went for the example used in the IOS NAT Load-Balancing for Two ISP Connections Configuration Guide [1].
I decided to use an upside-down Cisco 871-SEC/K9: use Vlan1 and Vlan2 for the routers and Fa4 for the LAN. I am hoping this is not an issue.
There is this weirdness with some connections, particularly FTP. I pinpointed the problem to the following scenario: if I do a couple of pings to 100.1.1.1 using the FastEthernet4 as the source address, this is what I get in the logs:
=== PING 1 ECHO REQUEST ===
*Mar 3 04:38:43.521: IP: tableid=0, s=192.168.60.4 (FastEthernet4), d=100.1.1.1 (Vlan1), routed via RIB

In the section "Ping 2 Echo Request" line 2 shows the NAT translating the packet to the address for the first provider but line 3 shows it routing it through the second one.
In this case, the ICMP packet goes through but it is problematic if the ISP restricts the service by source-address (like RPF) or there is some acceleration mechanism inside the provider cloud, other than just plain routing.
What am I missing? Here is the relevant part of the configuration. I deliberately disabled CEF to be able to debug the messages, but I *think* this may be altering the actual router behavior. This router does not have a "debug ip cef packet" command.

[1] http://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/100658-ios-nat-load-balancing-2isp.htmlHello.
This might be a bug in debug command or the IOS (without ip cef) you use; as routing is done before NAT (inside to outside).
To make sure it works fine with ip cef, just enable strict uRPF (or just ACL) on .1 and .33 interfaces and see if you see any packet sent over wrong interface.
PS: please check "sh ip cef 100.1.1.1"; I guess ip cef would tell you "per-destination sharing". -
Load balancing with use of router 881.
Hello,
I have two MPLS line and i want load balancing with the help of CISCO router 881. is it necessary that i require two router on both location.? if one location have firewall and one location have cisco router 881 then can i do a load balancing or i require two router each on both location ? What are the basic requirement that i need.
Thanks,

An 881 should be able to load share across multiple ports. Many routing protocol support ECMP, including BGP, but you need "special" hidden/secret commands to enable. EIGRP also supports unequal cost load sharing.
If an 881 supports OER or PfR, those too will do unequal load sharing, dynamically. -
ACE: load balancing servers using DMZ ports on FWSM
devices; (2 core with the ff config)
6500
fwsm
idsm
msfc
SETUP;
Servers are connected to the dmzs on the core
REQUIREMENT;
to load balance the servers
QUESTION;
Using the ACE module, is it possibe to load balance the servers which are connected to the port which is configured as DMZ?
Thanksdoes not matter where the servers are connected.
However, be aware that the flows from client to server needs to go through the loadbalancer BUT also the flows server to client.
So, you should be careful where you attach the ACE module.
The easier would be to attach to the DMZ as well between the FW and the servers.

EIGRP load balancing when using HSRP on LAN
Hi
I have a question about my topology. I have two routers with EIGRP on both of them connected through 2 ISPs to other site. On those routers i have HSRP runing. Now my question is: HSRP is standby/active protocol so when one router act as active will it send data to other site only through one ISP??? will load balancing work on WAN side? will routers use both ISPs or just one- the one which is active in HSRP when sending data???Hi sotiris_pafitis, may be I didn't understand what you mean but if the idea is to configure one static on each router (pointing it's ISP) and redistribute it in EGRIP, I disagree: is useless because the other router will prefer the static route due to its better administrative distance. Using EIGRP unequal load balancing is useless because it balanced EIGRP path with different metric, not different Administrative distance. Isn't it ?
If you want to use static route simply configure two static route on each router: one though WAN interface and the other through the LAN.
For example:
R1#conf t
ip route 0.0.0.0 0.0.0.0 192.168.13.3
ip route 0.0.0.0 0.0.0.0 192.168.12.2
The result is:
R1#sh ip route 0.0.0.0
Routing entry for 0.0.0.0/0, supernet
Known via "static", distance 1, metric 0, candidate default path
Redistributing via eigrp 100
Advertised by eigrp 100
Routing Descriptor Blocks:
* 192.168.13.3
Route metric is 0, traffic share count is 1
192.168.12.2
Route metric is 0, traffic share count is 1
In any case I think static router is not a good choice: in case of a fault on ISP 1, WAN interface can remain up producing a routing blackhole. If possible it's better to have a dynamic routing protocol between router and ISP, receving the default route and changing delay on interf to have the same metric for both the path

Issue in setting flex app in load balanced environment using SSL
I have developed the dashboard in my application using flex 3.0. For this I have used JSP wrapper around the flex application. My application runs on JBoss application server. for communication between flex app and my application i am using LCDS. HTTPService component is being used to receive data from the server. Channel definitions are given in service-config.xml for amf and http channels and for both secure secure and not secure mode. In my proxy-config.xml i have defined Channels and destinations.
services-config.xml

</destination>
In my development environment both secure and non secure mode were working fine. Now when I have deployed it behind the load balancer(which accepts secure requests only and if the request is not secure it redirects it to secure url) there is no response from the message broker servlet. One thing more I have observed is when the environment is non load balanced there are request like 'http://{server.name}:{server.port}/{context.root}/messagebroker/http'. and these requests are post request. But in load balanced environment with ssl the request is again like 'http://{server.name}:{server.port}/{context.root}/messagebroker/http' which is a post request and it is redirected to 'https://{server.name}:{server.port}/{context.root}/messagebroker/http' which is a get request. The content returned by this get request is null.
Looking for some comments
Thanks
Abhishek Guptaif the load balancing environment is already well configured, thes rest is very easy, there is no difference between a configuration of load balancing environment and a simple one, for you that is transparent, except the manual deployment and manual copying

Load-balance / autofailover using 2 ISPs
Good morning.
we have a T1 installed at our site and recently purchased a broadband connection from a different ISP. Our plan is to utilize both ISPs to Load-balance our Internet and setup auto-failover in case either one fails. We run exchange 2007 and host an ASP application so we can't afford to have our Internet disrupted.
currently we have a 1841 cisco router for the T1 and we're trying to figure-out if we need to purchase an ASA Firewall to setup the auto fail-over / load balance system.
Can you tell me which is the best way to do this and what equipment / model of cisco routers/ Firewalls do you recommend to implement this?
Thanks,
CollinHi Collin -- We appreciate your post but, as this pertains to ISR 1841, think you'd be better served in the Cisco NetPro Forums.

How to control a Load Balanced set in IaaS VMs using Text files
Hi,
I would like to control the Load Balanced nodes Using a resource to probe like active.txt in IIS than a Endpoint on the Management Portal.
The reason i need this is because the engineers in my team will have access to VMs but not to Management servers.
Any info on it is very helpful.
ThanksHi,
You can Control the access to the Load Balanced Set by using Network ACL. A Network Access Control List (ACL) is a security enhancement available for your Azure deployment. An ACL provides the ability to selectively permit or deny traffic for a virtual machine
endpoint. This packet filtering capability provides an additional layer of security.
Using Network ACLs, you can do the following:
Selectively permit or deny incoming traffic based on remote subnet IPv4 address range to a virtual machine input endpoint.
Blacklist IP addresses
Create multiple rules per virtual machine endpoint
Specify up to 50 ACL rules per virtual machine endpoint
Use rule ordering to ensure the correct set of rules are applied on a given virtual machine endpoint (lowest to highest)
Specify an ACL for a specific remote subnet IPv4 address.
Network ACLs can be specified on a Load balanced set (LB Set) endpoint. If an ACL is specified for a LB Set, the Network ACL is applied to all Virtual Machines in that LB Set. For example, if a LB Set is created with “Port 80” and the LB Set contains 3 VMs,
the Network ACL created on endpoint “Port 80” of one VM will automatically apply to the other VMs.
Hope this helps !

Load Balancing using Virtual IP on DMZ interface of 5520 ASA
We want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
These IPs are going to be NATted to all inside IPs.
Lets say our outside IP is X.X.X.X
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary.
When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.
I need configuration assistance with that.Hi Pratik,
The ASA does not support having 1 global/translated IP address on the outside mapped to multiple local/real IP addresses on the DMZ. If it did, the ASA would have no way of deciding if traffic destined to X.X.X.X is really meant for 10.15.1.2 or 10.15.1.3. For this scenario, you should use a dedicated load balancer or a router that supports policy-based routing.

Can anyone point me to some good documentation for configuring load balancing for oc4j instances?
I've seen a lot on metalink, but all dated back to 2002. I was hoping there was some new documentation for 10gR2.
I'm trying to load balance 3 webservice OC4J instances which each point to different API servers as the API servers themselves are single threaded.
Thanks for the assistance,
TonyThanks for the post. We had a little difficulty getting enough specifics out of the documentation to answer all our questions. But opened a TAR and got a good engineer who worked with us to get a custom load balancing solution that is working very well for us.
Thanks again,
Tony
For others out there that are interested, we ended up with a very simple load balancing setup that simply requires that the mod_oc4j.conf be modified to group the containers.
From Oracle:
To implement the solution, please execute the following steps:
1. Deploy application into different containers with the same application name.
2. Modify the mod_oc4j.conf as follows:

I have gone thru the following articles of metalink and some more from google
Configuring Web Cache as a Load Balancer for Application Servers
Create new middle tier node in existing Apps 11i environment using cloning and then load balance
Integrating and using Web Cache with Forms 9i for Load Balancing
Running Multiple OC4J Instances From a Single Install of 9iAS 1.0.2.2
LOAD BALANCING ORACLE APPLICATIONS ON UNIX
Load Balancing in 11i
OC4J Clustering Setup
OC4J Load Balancing for Forms 9i
Setting up 11i E-Business suite using a hardware load balancer
Sharing an APPL_TOP in Oracle Applications 11i
In Oracle Apps Concepts pdf, found that
Load balancing occurs when there are multiple installations of web server, forms server, reports server, concurrent manager server etc
Lets consider forms server component of middle tier
Can there be multiple INSTANCES of forms server within SINGLE INSTALLATION ???
If it has to be MULTIPLE INSTALLATIONS, then it will require multiple physical machines
What is software load balancing then ???
Also read that
Oracle 9i AS instance is combition of Oracle HTTP Server (OHS) and one or more instances of Oracle9iAS Container for J2EE (OC4J)
Thus software load balancing can be implemented for Web server component of middle tier using multiple instances of OC4J ???
Forms metrix server configuration is hardware load balancing ??
What about Oracle9iAS Web Cache clustering ??
Please clarify the doubts and suggest me the way
Thanks a lotdear all can any one help me on the following;
We want to install Oracle Apps 11.5.9 on 4 IBM AIX 5L boxes, the first node
will hold the database , concurrent and Admin Tiers. as for the other 3 nodes
it will hold the Forms/Web Tiers and we need to use forms metrics for load
balancing taking into consideration that we can't use Shared APPL_TOP. we tried
to find the way how to install and configure this solution but all the
documents are talking aboout the concept only and this concept is applicable.
We need the exact steps on how do the installation either using rapidwiz or any
thing else

Load Balancing Forms and Reports with Web Cache
We are planning to add a second OracleAS 10g middle-tier application server to an existing 10g middle-tier.
Both middle tiers will provide Forms and Reports.
Users must pass through two static HTML pages before starting Forms.
We plan to use Web Cache to load-balance (probably using round-robin) between the two middle-tiers.
Does anyone see any problems with this solution?
All comments/suggestions welcome.
Thanks,
JimYou could also load balance the two OC4J's using standard servlet mechanisms. I know that there exists a couple of good notes on Metalink. Go and do a search.

SAP GLM Print Request - Load Balancing of WWI server
Hi GLM Experts,
I am using new GLM + module that generates labels based on Print Requests. I am unable to understand how I can load balance the WWI services when there are multiple label printing requests.
In GLM + we associate a WWI to a Print Station and which can then be associated with a printer. So in the configuration we are tying up a printer a WWI.
Also during label printing, if the scenario uses print request module, then the use need to select a print station and printer. What happens if the WWI related to the print station is down?
For example I have two services in WWI server GENPC1 and GENPC2. I created WWII and WWI2 as two print stations. I will associate my printer PRNWWI to both the print stations WWI1 and WWI2.
During label printing if the user picks and WWI1 and Printer PDNWWI and if the GENPC1 WWI server assocaited with print status WWI1 is busy and down I want WWI GENPC2 to generate the label?
How to setup the above load balancing or fall back? Please let me know.
Thanks
PugalDear Pugal
we are not using GLM + and I am not sure about the technqiue used there to handle load balancing. Regarding general WWI setup I assume you know this Note: EH&amp;S: Availability and performance of WWI and Expert servers
On the top there is a further SAP Note abvailable which might be of interest. This is referenced here:
http://de.scribd.com/doc/191576739/011000358700000861002013-e
May be check OSS note: 1958655; OSS Note 1155294 is more related to normal WWI stuff; but may be check it as well. May be 1934253 might help better
May be this might help.
C.B.
PS: may be check as well: consolut - EHS_MD_140_01 - EH&amp;S-Management-Server einrichten
The load balancing of synchron WWi servers is donein the "RFC" layer, therefore you have no inffluence here, for asynchron WWI servers you can do a lot to manage the WWI load balancing by using "exits" etc. -
System with load balancing server
Hi All,
We are having SAP NW 7.0 Portal and back end we have R3 implemented in a cluster environment. The system object in EP have used "System with Load balancing" template; using the LOGON group and the other related parameters.
But we have some problem with the ITS and WAS parameters; since we are using some Transaction iViews.
Let me explain.. for the R3 cluster we have 2 systems PROD1.domain.ext and PROD2.domain.ext. Now in the system object in portal, how to specify the parameters for ITS and WAS parameters? Since the host name in these we need to specify a single server which defeats the basic purpose of having clustered environment.
Can any one please help in resolving this issue.
Thanks,
SravanthiHi Sravanthi,
Please check the below for finding ITS and WAS parameters from backend :
For ITS - Go to SE37 >> Utilities >> Setting >> Click on ICON Right Top Corner in popup window >> Select Internet Transaction Server >> you will find the Standard Path and HTTP URL.
For WAS - Go to SE37 >> Run FM - RSBB_URL_PREFIX_GET >> Execute it >> you will find PRefix and PAth paramter for WAS.
Please refer to this may help step-by-step : How-to create a portal system for using it in Visual Composer
Hope it helps
Regards
Arun
