Load Balancing 11i for both 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 BALANCE BEHAVIOR FOR 7600 ON ETHERCHANNELS

Hi Everyone,
Currently I'm planning to implement ether-channels on 7600 routers, but there's something that's still not clear to me, regarding the load balancing behavior, for L2VPN and L3VPN.
I've read that 7600 in MPLS default load balance behavior is to take the SIP and DIP if present and the bottom of the stack label or the 5th label depending upon the number of labels on the stack. In l2VPN scenarios when ether-channel is used, if no IP traffic is present what is the default behavior of the etherchannel to calculate the load balancing hash function to select a given link on the bundle.
I'll appreciate any feedback regarding this.

Hi Louis, you could set default routes on the ASA's with tracking, and use ospf downstream to inject the default route in to the network with default information originate - this will only advertise out a default route if it has it in the routing table. With SLA you can track internet reachability by IP SLA echo to something like 8.8.8.8. Both sides can advertise this in to the network, if one goes then there is one left. Just be mindful of the policies and NAT required, you will have to duplicate the rules on the ASA's. With the NAT you have to ensure, that outgoing traffic comes back in the same path it left so it doesn't break connections.

Load balancing algorithm for groups in RZ12

Hello,
I would like to know the load balancing algorithm for groups defined in RZ12.
I know that log on groups for external connections are administered via SMLG and table RZLLICLASS.
I also know that RFC resources can be managed for RFC logon groups via RZ12.
Kind regards,
Peter

Hello!
Found this post while searching information about RFC and Logon Groups...
I have some mess in my head with SMLG functionality and RZ12. As I know SMLG we can use to distribute users to application server instances, it gives us good achievement in performance. With RZ12 we can distribute RFC connection of particular job for parallel execution on predefined application server. With SMQS and SMQR transaction we can set "Name of AS Group" to route RFC-execution on certain server or servers. But I have troubles with understanding. Imagine, we set up group 1 with 2 servers (name it RFC_GR1), and group 2 with another 2 servers (name it RFC_GR2). How could qRFC scheduler decide on which RFC server group (RFC_GR1 or RFC_GR2) distribute RFC-execution? How to interact "Name of AS Group" with RFC groups if we can set only one group? How could we distribute RFC-execution depending on our logon groups (smlg)? We would like to distribute RFC depending on SAP logon groups. Is it possible? Or do I compare apple and orange?

Load balancing plugin for Sun WS 6.1

Where can I find details about the load balancing plugin for Sun Java Web Server 6.1?
Can I work around that by using the reverse proxy plugin and configure to work as a Load balancer?
thx
Anand

Details about using the reverse proxy plugin can be found here:
http://docs.sun.com/source/819-0902/rpp61.html
The reverse proxy plugin can be used for load balancing. Use the service-passthrough Service SAF for this purpose. You are particularly interested in the "servers" parameter
"servers - A quoted, space-delimited list of the servers that receive the forwarded requests. Individual server names may optionally be prefixed with http:// or https:// to indicate the protocol and/or suffixed with a colon and integer to indicate the port."

Load Balance & redundancy for internet from 2 different sites?

Hi,
we have 2 core sites where our servers are situated. Both sites are connected via a ptp link.
All of our clients/sites reach these two sites via our MPLS network and they never route via the ptp link which is solely used between the two core sites.
One of the sites has an ASA which goes out to our internet. We are thinking of replicating this on our other site.
How would we go about load balancing the internet connection ie 50% go out on site A & 50% go out on site B?
And if site A goes down, everything goes out via site B and vice versa?
Diagram attached....
Thank you,
Louis

Load balancing across multiple paths to Internet

Hello,
I have a 2821 router. Currently, I have two bonded T-1 circuits to the Internet.
I would like to add a DSL circuit to augment the T1s. I would also like to load balance across all of the circuits. Currently, IOS performs inherent load balancing for the T1 circuits. The DSL circuit is from a different provider than the T1s.
The T1s are coming from a local ISP that runs no routing protocols within their infrastructure. (They run static routes and rely on the upstream provider for BGP.) The DSL provider is a national telecom carrier.
What is the best way to perform load balancing for this scenario?

Here is the answer (sort of) for anyone reading this post with the same question:
No matter which way I choose to do it, the trick is to have the local ISP subnet advertised via BGP through both pipes. The national telecom DSL provider will not advertise a /20 subnet down a DSL pipe. (Ahh, why not? =:)
Had the secondary pipe been a T-1,T-3, or other traditional pipe, I could have used a load balancer like a BigIP, or FatPipe device or possibly CEF within the IOS.
Case closed. Thanks to everyone that took a look.
Doug.

ACE Load Balancing Configuration For NATed User Traffic

Hello,
I am currently working on a requirement where the shared application services will be hosted in DC and these services will be accessed by multiple (thousands) users from different corporates/customers. The user traffic will be hidden behind customer's proxy servers or firewalls so the load balancer (ACE modules) services hosted in DC will not be able to see requests coming in from induvidual users IP addresses.
In this scenario what are options of load balancing are available in Lyer3/4 and Layer7 ?
Thanks in advance for your help.
Sanjay

Hi Sanjay,
In a set up where all users are coming from behind a proxy, all users will be loadbalanced to same server thus overloading it. This is when you are doing standard L3/L4 LB.
In the situation of proxies, for HTTP applications you shall use L7 LB and use information(cookie) in HTTP client request or server response. The ace will use this information to stick the user to same server for persistence. If a client comes with no cookie it will be loadbalanced according to the predictor method configured. Below is the link for L7 configuration example and other TS steps you can take while configuring L7 policies on ACE. For more informatin i would suggest reading ACE user guide too.

If you have any questions please feel free to ask.

Problem Load Balancing connections for Grid Control Console on port 80!

I have two OMS and I'm balancing connections for Grid Control Console using a Software Load Balancer according with "Oracle Enterprise Manager Advanced Configuration". I have success where the load balancer is listening on port different to 80. When I configure Load Balancer to listen on port 80(architecture requirement) and distribute load between the two OMS(Port 7779), when login to Enterprise Manager Console the URL on the web browser changes to the port configured for HTTP server (port 7780) wich produces an "unable to connect" error message; and this behaviour also happends in some of the internal links of Grid Control Console too. Any ideas?
Thanks in advance!

Load Balancing Rules for BIGIP

I am running single-user applications that fall into two
categories:
1.) recording and uploading audio
2.) streaming audio and video over rtmp, rtmpt, and rtmps
The files being streamed are on a NAS.
Is anyone using a hardware load balancer in conjunction with
FMS? Is it possible to do SSL offloading for rtmps? Would anyone be
willing to share your pools, iRules, and other configuration data?
Thanks!

SCEP updates for servers without internet access

I have servers that are Windows Server 2012 and Windows Server 2008 R2 that CANNOT have internet access. I pushed the CM client to them and the SCEP client but they cannot get the SCEP updates. The error in the WindowsUpdate.log is:
2014-04-25 09:13:59:695 992 b94 Misc WARNING: WinHttp: SendRequestUsingProxy failed for <http://download.windowsupdate.com/v9/1/windowsupdate/redir/muv4wuredir.cab>.
error 0x8024402c
I think the Windows Update Agent is trying to update from MS.
When I run RSOP.msc, I do see that the CM server is listed as the WSUS server and was updated in local group policy which is what the CM client is expected to do.
What do I do in a situation where the machine does not have internet access and I need to update the WU agent?
Thanks,
Mike
