How to remote deploy across load balanced servers

I have a server farm that is load balanced, how would I deploy to 15 servers at the same time? Or what is the process to do such a thing using SJWS?
Doing it manually one at a time just doesn't make sense...

Hi,
this is a known issue as you will be executing 2 report requests, one to execute the report and the other to retrieve and display the report, in this scenario the second request( to do the display) is forwarded by the LBR to the reports server where the request was NO executed so the error you are getting is expected.
To resolve this please check the following notes.
Rep-52251: Cannot Get Output of Job Id###, when Calling Reports from Forms (Doc ID 367887.1)
Maintaining 6i Run_Report_Object Code in 10.1.2 Without Employing Clustering/HA (Doc ID 358436.1)
Regarding the second question the issue I think is related to cacheSize and/or maxCacheFileNumber settings in your reports server configuration file.
Hope it helps.
Regards

How to configure RZ12 and SM59 ABAP connection settings when we have work with Load Balancing servers rather than a specific server .

Hi ,
If we have a specific server say 10.10.10.10 (abc.co.in) on which we are working, Then under RZ12 we make the following entry as :
LOGON GROUP          INSTANCE
parallel_generators        abc.co.in_10         ( Lets assume : The instance number is 10 )
Now in SM59 under ABAP Connections , I am giving the following technical settings:
TARGET HOST          abc.co.in
IP address                  10.10.10.10
Instance number          10
Now if we have a scenario of load balancing servers with following server details (with all servers on different instance numbers ) :
10.10.10.11
10.10.10.13
10.1010.10
10.10.10.15
In this case how can we make the RZ12 settings and SM59 settings such that we don't have to hardcode any IP Address.
If the request is redirected to 10.10.10.11 and not to 10.10.10.10 , in that case how will the settings be.

Hi,
No one using FMS behind a load balancer? No one using RTMPT?

How does Tuxedo 10.0 load balance across the BRIDGE?

Is the load balancing round robin or does work done factored in?

Yes and no. In all honesty, see if this white paper helps answer your question: http://www.oracle.com/technetwork/middleware/tuxedo/overview/ld-balc-in-oracle-tux-atmi-apps-1721269.pdf

ACE load balancing servers on different subnets...

Hello,
I have the following issue.... need to load balance traffic between two servers already working in two different subnets (vlans), at this point is highly desirable to avoid changing IP addresses. Is it possible to accomplish this goal using ACE? routed or bridged mode? is it strictly necessary to have all servers belonging to a serverfarm in the same subnet?
Thanks in advanced for your support.

Hi,
You can do this, but you have to use client-NAT (Source-NAT) to force the return traffic to pass back through the ACE. You also then need static routes in the ACE context to point at each server. PBR is an alternative approach but I have not implemented that in a live network. The important thing is that the ACE sees both sides of the conversation.
The following extract from a configuration shows the basic principle:

Caching across load-balance Webservers

My application uses a round-robin load balancing mechanism with 4 Webservers. We have just upgraded from 1.3 to 1.4.0_1 and have discovered that our jar caching only works for individual servers. E.g., if you go directly to the same webserver every time, the jars will not be re-downloaded - however if you go to each of the 4 servers, you will have 4 copies of the same jar file.
Note: this worked perfectly under 1.3. All the web content is EXACTLY the same on all of the servers. All of the jars have the same version number.
The Plugin documentation makes no mention of examining the server host IP for the jar content - only the jar version. So, my question is:
How can we prevent the jars from being downloaded multiple times?

LRT224 Load Balancing Servers

I get the process of load balancing outbound traffic, and even protocol binding so that servers send out traffic only on a specific WAN port. What I do not get is how to load balance INBOUND traffic also to those servers and ensure that the servers response goes out on the interface that it originated.
I have two 50mb internet connections from different ISPs. Each with a static IP address.
The web server is on a private IP address with appropriate forwarding.
The web server IP address is bound to WAN2 which is the DNS address of the web server.
All works perfect. Outboud traffic from the web server exits from the appropriate WAN port while residual traffic is load balanced.
Now, I want to add an A record to the DNS for the web server so that INBOUND traffic ot he web server is balanced and providing a redundant service. However, the protocol binding should not allow any outbound connection through WAN1. Right?
So my question is, is this setup impossible? Do we forget the protocol binding and hope that the outbound responses from the server exits through the originating port? Is there another method? Or, do I need a more advanced router?
I do not even want to consider DMZ even as this is impossible since I am utilizing both ports as WAN ports. Anyone have any suggestions to do this?
Thanks
Mark

Sorry I misunderstood.
IMO for this to work on an LRT224 you would need:
A second network adapter in the Server and the Server configured to answer requests on both NIC's
Protocol Binding the second Server NIC to the other WAN port
A DNS Hosting Service that support DNS Round Robin or you would run your own DNS Server with Round Robin DNS capabilities
These days I'm seeing DNS propagation with namesecure only taking a few hours instead of the advertised 96hrs.
Please remember to Kudo those that help you.

Load balance servers with 3560?

Here is my scenario...
I have two servers that are both connected to a single 3560 (SMI).
These two servers are in a primary/secondary relationship. Right now, if the primary server goes down - we need to manually configure the secondary server to take over.
I have two questions...
What is the best way to set up fault tolerance with these devices, so the secondary server will automatically kick in if the primary goes down?
In addition to that, is there any type of load balancing feature we can use on this 3560...so both the primary/secondary servers can run at the same time?
Ideally, we would like communication to the second server kick in when the link to the primary server gets too congested.

your best bet is to use IOS SLB or a content switch such as the cisco CSS series.
please see the following links for more info on ciscos CSS and SLB capabilities:

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?
Thanks

does 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.

How to modify my wccp load-balance

hi all
I've two WAE in my core, 612 (10.99.100.95) and 674 (10.99.100.96)
and 3750 stack is my core switch
I configured wccp tcp-promiscuous router-list 1 l2-redirect l2-return mask-asign in both WAE
and wccp load balance is work fine
but in my environment ip subnet, like 10.10.10.0
10.10.10.1 ~ 10.10.10.128 will load balance in WAE-612
and 10.10.10.128 ~ 10.10.10.255 will load balance in WAE-674
and I want to reverse it
I try to change WAE ip address
but it still haven't change
anyone could help me ?
thanks

This isn't necessarily a problem. WCCP uses a hash table of 256 buckets to distribute traffic across the devices in a service group. When you have two devices in the service group, each one gets 50% of the buckets (i.e. WAE1 gets buckets 0-127 and WAE2 gets buckets 128-255). When a device leaves the service group, the buckets it was allocated are reassigned to the remaining device in the service group. When a device is added to the service group, it will get 50% of the buckets, but it's not guaranteed that it will get the same 50% it previously had.
So in your case, when the 674 rejoined the service group, it's possible that it was allocated the buckets that the 612 was previously handling the 800 connections on. This is normal behavior and not anything to be alarmed about.

Zach

How can I debug Aggressive Load Balancing on the WLC ?

Hello Cisco-Experts,
I'm looking for the command on the Cisco WLC to debug Aggressive Load-Balancing.
There is a nice document, ID 107457 describing this feature, but it lacks the command.
Please investigate and help me and maybe improve YOur documentations.
Thanks in advance
Winfried

Hello NetPros,
I have disabled now "Agressive Load Balancing" now on the WLC. To my surprise, still Load-balancing packets are received from our HREAP-APs via a WAN-Link on the central WLC.
Here is an example:
Tue Jan 13 15:35:59 2009: 00:1c:bf:4a:3f:2e LBS data stored for Mobile 00:1c:bf:4a:3f:2e from AP 00:23:5d:0e:e9:e0(0) new saved RS
SI (A -128, B -53), SNR 41, inUse 1, [rcvd RSSI (A -128, B -54), SNR 40]
Tue Jan 13 15:35:59 2009: 00:1c:bf:4a:3f:2e LBS data rcvd for Mobile 00:1c:bf:4a:3f:2e from AP 00:23:5d:0e:e9:e0(0) with RSSI (A -
128, B -55), SNR 42
Tue Jan 13 15:35:59 2009: 00:1c:bf:4a:3f:2e LBS data stored for Mobile 00:1c:bf:4a:3f:2e from AP 00:23:5d:0e:e9:e0(0) new saved RS
SI (A -128, B -54), SNR 41, inUse 1, [rcvd RSSI (A -128, B -55), SNR 42]
It is remarkable that the MAC-addresses of many of the WLAN-clients do not belong to our company and packets are send via a WAN-link.
Why do I see these packets while load-balancing is disabled ?
How is this working ?
Thank You for any explanation.
Winfried

How does IronPort assist in load balancing?

There are plans to put a load balancer in front of an IronPort cluster of 6. As of now, we have Mx record priority (Round robin) based load balancing.
Does an ESA has the intelligence to automatically reject incoming connections if other ESAs in the cluster is idol? Or, in other way, does ESA has the intelligence to reject incoming connections if it sees a series of connection attempts from the same source? Or, does it have intelligence to reject incoming connections if it is devoid of any resource to process any new messages?
Thanks,
Chandan

No. The ESA will still act in the same stand alone fashion - so, it will act independently with the traffic that is presented. Other appliances in cluster would not recognize the other appliance's traffic or status for handling mail that is processed --- remember, with the ESA, in cluster - the only thing that is shared is the configuration between cluster appliances.
The traffic handling and load balancing aspect would be based on the 3rd party software/appliance sitting in front of the appliances --- then control the pool of appliances that you have set from there.
I hope this helps!

Adding second 5508 Wireless Controller, how to best configure for load balancing and redundancy?

We recently purchased a second 5508 wireless controller (both licensed for 100+ AP's). What is the easiest way to configure and add the second controller so I can split the load between the 2 controllers and provide failover capability? I do not want to run in an active/standby mode since that will effectively cut our AP capacity by half even with both controllers running.
Should I just manually configure the new controller (long and drawn out process to configure all the parameters), backup the current controller configuration and import to the second controller (then change the ip address) or is their an easier way to cause the two controllers to synchronize the configurations?
We are currently running 7.0.240.0 on our active controller and I would rather not upgrade it until we get the new controller online so I can have less downtime and fail AP's between controllers.
What can you recommend?
Jim

I'm assuming then, when I update the software on the controllers I won't be able to choose which controller is primary for an AP anymore and will lose access to the 100 AP licenses (and the capability to have 100 AP's registered, 100 licenses on each Controller).
Read the Deployment Guide. It should mention that you can choose which controller is the "primary" and which one is the "secondary".
If I'm not concerned about quick failover can I still assign a primary and secondary controller for each AP and utilize all 200 AP licenses that are split between the 2 controllers?
You sure can. But this "old school" method is a very expensive method. Why? Because this means that you have two controllers with similar AP licenses. The newer AP SSO means one controller has a full license and the other has only an HA SSO license, which is a lot cheaper.

How to trace users across different Application Servers?

Hi,
We trace users using ST01. But how do we trace users logged in to different application servers? Please help.
Regards
MK

Hi Ahmed,
SM51 or AL08 shows in which Application server the user is logged in. But ST01 does not allow us to select or to specify the application server while tracing a user. Can you be a little more vivid. How do you specify the application server in ST01?
Please help.

ACE 4710 multiple services running on load balanced Servers

Our Exchange 2010 hub servers run multiple services/ports: smtp, www, pop3,135, 143, https, 993, 995, 6001,6002,6003,60200,60201,8400, and 8402
what is the best way of balancing these servers so that if only one of the services failed on a server, it would switch only the failed service to remaining servers.
At present I only use an smtp probe, so as log as that sevrice is running the server is marked good. It seems to me the setup could get quite complicated so any responses welcome.
