Any reference site using CISCO or Big -IP for load balancing

we are considering switch based load balancing solution for middle tier. Are there any pointers , reference sites ?
I am aware of sites using Metrics Server for forms server load balancing. We are not planning to use MS.

Hi Naveen,
You need to do following steps (Try first in Test env ;)
1. Login in to Oracle Applications Manager Portal
2. Navigate to AutoConfig section (Site Map->AutoConfig)
Configuration Wizards
Click on "Launch Wizards"
3. Fill in fields as instructed.
(Basically you need to put Vhostname + Apache Port number)
4. Run autoconfig
If you haven't got those wizards:
1. Install Latest OAM patches (It is good idea to be on the latest patches of technology stack of Apps).
2. Or if you cant, you can to try edit Context XML file for each server manually:
2.a
s_webentryhost <Vhost>
t_session_persistent true
t_dns false
s_webentrydomain <your domain>
s_webentryurlprotocol http
s_active_webport 8005
-- If you havent got mentioned parameters in the XML context file you need to apply latest template autoconfig patches
2.b
run autoconfig
Hope it helps,
Yury

Is there any constrain in using the same order type for MTS and MTO

Hi,
i have the constrain to use single production order type .
Can i use single order type for MTO and MTS.
is there any constrain in using the same order type for MTS and MTO.
pls help me.

Hi,
There is no constraint or limitation in using the same production order type for MTS and MTO . Settings in requirement class and material master will mainly control whether the flow is MTS or MTO.

Hello Krzysztof,
Another set of good/interesting questions posted. Thanks!
I will try to clarify your doubts.
In the output below both resources (proxy-connections and ssl-connections rate) are configured with a min percentage of resources (column Min), while 'Max' is set to equal to the min.
ACE/Context# show resource usage
                                                     Allocation
        Resource         Current       Peak        Min        Max       Denied
-- outputs omitted for brevity --
proxy-connections             0      16358      16358      16358      17872
ssl-connections rate          0        626        626        626      23204
Most columns are self explanatory, 'Current' is current usage, 'Peak' is the maximum value reached, and the most important counter to monitor 'Denied' represents the amount of packets denied/dropped due to exceeding the configured limits.
On the resources themselves, Proxy-connections is simply the amount of proxied connections, in other words all connections handled at layer 7 (SSL connections are proxied, as are any connections with layer 7 load balance policies, or inspection).
So in this particular case for the proxy-connections we see that Peak is equal to the Max allocated, and as we have denies we can conclude that you have surpassed the limits for this resource. We see there were 17872 connections dropped due to that.
ssl-connections rate should be read in the same manner, however all values for this resource are in bytes/s, except for Denied counter, that is simply the amount of packets that were dropped due to exceeding this resource.
For your particular tests you have allocated a min percentage and set max equal to min, this way you make sure that this context will not use any other additional resources.
If you had set the max to unlimited during resource allocation, ACE would be allowed to use additional resources on top of those guaranteed, if those resources were available.
This might sound a great idea, but resource planning on ACE should be done carefully to avoid any sort of oversubscription, specially if you have business critical contexts.
We have a good reference for ACE resource planning that contains also description of all resources (this will help to understand the output better):
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/configuration/virtualization/guide/config.html#wp1008224
1) When a resource is utilized to its maximum limit, the ACE denies additional requests made by any context for that resource. In other words, the action is to Drop. ACE should in theory silently drop (No RST is sent back to the client). So unless we changed something on the code, this is what you should see.
To give more context, seeing resets with SSL connections is not necessarily synonym of drops. As it is usual to see them during normal transactions.
For instance Microsoft servers are usually ungracefully terminating SSL connections with RESET. Also when there is renegotiation during an SSL transaction you may see RESETS, but this will pass unnoticed for end users.
2) ACE will simply drop/ignore new connections when we reach the maximum amount of proxied connections for that context. Exisiting connections will continue there.
As ACE doesn't respond back, client would simply retransmit, and if he is lucky maybe in the next attempt he will be able to establish the connection.
To overcome the denies, you will definitely have to increase the resource allocation. This of course, assuming you are not reaching any physical limit of the box.
As mentioned setting max as unlimited might work for you, assuming there are a lot of unused resources on the box.
3) If a new connection comes in with a sticky value, that matches the sticky entry of a real server, which is already in MAXCONNS state, then both the ACE module/appliance should reject the connection and that sticky entry would be removed.
The client would at that point reestablish a new connection and ACE would associate a new sticky entry with the flow for a new RSERVER after the loadbalancing decision.
I hope this makes things clearer! Uff...

Telmo

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

SSP5: Using multiple JVM for load balance performance?

Sun 12 MAY 2002
Apps 11.0.3
SSP5 patchset I
HP UX 11.0
db 8.1.7.2 (64-bit)
Load 60 concurrent sessions, each spawning 2.5 - 3 http connections.
CPU 3:750Mhz
RAM 8G
Is anybody using multiple JVM for load balance?
What is your ratio of JVM to concurrent iP sessions?
Are you running Apache/Jserv on a server with any other applications, or is Apache by itself?
If you are not using JVM, how many httpd processes do you get before Apache implodes? We stopped in the water at 90 httpd processes, but performance degraded starting at 70 sessions.

Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

Is it possible to use UCS Blade Servers in ACE Load Balancing

Hi all ,
Is it possible to use UCS Blade Servers in ACE Load Balancing ?? Please note that UCS Blade Servers are not connected directly to 6500 Switch where ACE Module installed .i am expecting a good suggestion from whether ACE or Switching Expert
Thanks in advance
Sanjeevi

There is nothing that would prevent you from loadbalancing the applications that run on UCS servers. ACE can loadbalance applications that are directly L2 attached (bridged or routed mode) or even servers that are multiple hops L3 hops away using one-armed mode with source nat. The key to this is that the return traffic from the server needs to make it back to the ACE.

Unable to go any https site using FF and safari. Mac OS 10.6.7. Https sites are not displayed at all.

I was able to do all https sites before. Recently I have notied that whenever I go to any https site , the site is not displayed at all.
FF 4.0.1 and safari
e.g. go to www.skype.com and click on login link
can't login to FB
Can't display https://mail.yahoo.com
funny thing is I can't even go to http://www.apple.com
I get blank page and the browser keeps spinning.
Cleared all cache.
Pl. help.
thank you so much for your help.

Those sites display correctly provided they supply HTTPS. Which Yahoo does (HTTPS) and Apple doesn't on their main page (it's HTTP), but the forums here are HTTPS.
Go to your KeyChain Access.
Under Preferences > Certificates set the following
1: Best Attempt
2: Best Attempt
3: OCSP
Reboot the machine.
When you request a secure site it will check the certificates immediately instead of using Apple's outdated lists which require Apple to include them in a Software Update.
If someone is using these outdates certificates maliciously then that's likely the problem.
Also install the HTTPS Everywhere Add-on for Firefox, to ask websites to provide HTTPS. They always can't do it because of third party unencrypted content.
Also when that's finished. Run all the cleaning and maintenance aspects of the free OnyX and reboot (you can cancel reboots in between jobs)
Does a good job of cleaning out gremlins.

Any methods to simulate Cisco IronPort WSA appliance for practice

Similar to GNS3 on which we can simulate ASA/Routers, same way any other methods to simulate Cisco IronPort WSA appliance for practice or testing? Please let me know. Thanks.

You can download the virtual WSA. I have not tried it so I'm not sure how it works without a license.

Cisco 886VA - Multiple PPPoE Line Load Balancing

Dear Cisco Community,
due to the need of increased bandwidth a customer ordered three ADSL6000/576Kbit lines from the same ISP. Dial-in is done with PPPoE and the IP is not static.
- Is it possible to load balance between the three ISP lines with this router as the Cisco 886VA-K9 (Advanced IP Services) doesnt support PFR/OER I want to load balance per session, meaning each TCP session takes the same path, the next TCP session takes second path, next TCP session takes third path, then first path again and so on.
- I did read the tutorials avaiable, but they don't discuss how the lines are used in round-robin fashion, just how to distribute different traffic on different lines. (https://supportforums.cisco.com/document/32186/dual-internet-links-nating-pbr-and-ip-sla?page=1) or (http://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/100658-ios-nat-load-balancing-2isp.html)
- How would you solve this challenge?

Hey there,
I managed to fulfill my requirement..
If its a cluster on same machine or across machines, this should work
1. Login to machine, cd $DOMAIN_HOME
2. mkdir -p Apex_lsn_config/AdminServer Apex_lsn_config/<MS1> Apex_lsn_config/<MS2> # MS1 and MS2 are the Managed Server names as appropriate
#If you are planning for cluster spawning MS's across machines, make sure you create the dir's on step 2 for each machine respectively. (in my case $DOMAIN_HOME is not shared)
3. Copy apex-config.xml from the /tmp/apex or whatever location you have it currently to Apex_lsn_config/<MS1> Apex_lsn_config/<MS2>
4. cd $DOMAIN_HOME/bin; cp -p SetDomainEnv.sh SetDomainEnv.sh.orig #Backup the file
5. Append -Djava.io.tmpdir in SetDomainEnv.sh as below for JAVA_OPTIONS # Do it on both machine if you are not sharing DOMAIN_HOME and planning cluster across machines
-Djava.io.tmpdir=$DOMAIN_HOME/APEX_CONFIG/${SERVER_NAME}
Hint: Search for "iterativeDev" and append the same line with -Djava.jo.tmpdir
6. Modify "java.io.tmpdir" from the web.xml file of apex.war as below and re-deploy the war
<context-param>
<param-name>config.dir</param-name>
<param-value>${java.io.tmpdir}</param-value>
</context-param>
7. Bounce Weblogic Admin and Manged Servers. Make sure to tail the Managed Server log to see apex-config.xml is picked from the new location.
8. Brew a Coffee for yourself :)
- You find the instructions on creating a cluster from weblogic documentation, the steps mentioned above are only to overcome the bdb locking issue whilst creating a cluster.
Did it help?

Best Option (if any) for Load Balancing Distribution Point(s) on Same LAN

Hey Guys -
I've got a simple question this time. We use SCCM 2012 R2, manage ~800 systems at 3 locations, but perform most work at our main office where this scenario takes place. Here, we have a single DP on-site which is a separate VM than our Primary
which is also local.
Recently, our PC Lab tried running our OSD TS on 16 systems which were each started 1-2 minutes apart. When run on a single brand new PC connected via GB network, the OSD TS takes a couple of hours to complete so with 16 it really caused some
issues. We had a couple of Programs/Packages/Applications which actually timed out due to the default 120 minute max run time. We don't usually image 16 at a time, but often do 2-3 at once so are looking to find a solution to speed things up anyways.
My Question
What is the best solution / method for implementing any type of load balancing on a single LAN? I'm not asking for true load balancing, but simply any solution where multiple systems running a TS can pull from more than a single local source if possible.
We do not use multicasting and from what I've been told it will not be a possibility as it causes havoc on networks so it's out. I know that some clients can share content depending on deployment configuration, but don't know how / if this applies to OSD
Task Sequences.
Any suggestions or ideas? Thanks!
Ben K.

Agree, 16 machines is not a lot. I would normally go for about 2000 machines per DP depending on pkg/img size etc. Whats the size of that rebuild? Image + packages? Do you do a full DL before starting or is it started from WinPE?
Our BranchCache tools will of course help, regardless of how fast your gig link is since data will be pulled from more sources, but think your issue is more network related? If the images is 5 gig and you add another 5 gig of packges in the sequence a 1Gb/s
link should pull that 16 * 10GB=160GB in about half an hour. So think dont think you are having 1Gb/s from server to clients.

How to see the Source IP Address of a client using ACE One-armed-mode to load balance HTTP proxy request

I'm using an Ace 4710 Appliance deployed in One-Armed mode, using Source NAT to loadbalance HTTP request to a couple of Proxy servers.
Everything is working fine, but the thing is that I can't see the Clients IP addresses on Proxy's logs, so I can't keep track of them.
The Interfaces and Nat configs are:
interface vlan 200
description Server-Side-VLAN
bridge-group 5
nat-pool 5 10.1.1.5 10.1.1.5 netmask 255.255.255.0 pat
service-policy input VIPS
interface vlan 300
description Client-Side-VLAN
bridge-group 5
interface bvi 5
ip address 10.1.1.3 255.255.248.0
description Client-Server-Virtual-Interface
ip route 0.0.0.0 0.0.0.0 10.1.1.1
and the policy map looks like this
policy-map multi-match VIPS
class Port80
    loadbalance vip inservice
    loadbalance policy Port80
    nat dynamic 5 vlan 200
Resource assignment:
sticky ip-netmask 255.255.255.255 address both RESOURCE-CLASS
timeout 5
serverfarm Service80
Any suggestions will be appreciated,
Thanks

Hi Kanwal,
Thanks for your quick reply,
I've already tried this but it didn't work. The problem is that I don't manage the proxy servers so I rely on their skills to see the logs.
The Proxies are Squid. Do you know if they need to do something else on the servers to see that field of the HTTP header?
But I'll try again tomorrow and let you know how it goes.
Thank you again.

Cisco SA 520W set up for load balancing but traffic not routing properly?

Forgive me cause my networking skills are a bit rusty. So we have an SA520W that sits in-between both of our ISP connections. One connection is 4 bonded T-1s and the other is a shared 50/20. I have configured the SA520W with the optional port set to load balancing. I set the protocol bindings to be HTTP and HTTPS to go over the optional WAN which is the 50/20 yet when I do speedtests I am getting very mixed results. Sometimes it reflects that I am on the 50/20 and other times I just get 5 down and 5 up. and then other times it is a mix between the two, like 5 down 15 up.
It is just weird. I don't understand am I missing some other protocols I need to bind other than HTTP and HTTPS? It isn't just speed tests either I have noticed some weird web page loading issues as well. You can go to a page and it loads really fast and then later on...
This topic first appeared in the Spiceworks Community

Hi accidentexchange,
Did you fail to log in when accessing the SA 520W thru both HTTP and HTTPS?
https://LAN_IP_address_of_SA520W/
http://LAN_IP_address_of_SA520W/
Furthermore, can you give us an overview of your network topology and user info. If possible, can you provide us the configuration and dbglogs from your SA 520W so that I can forward to the development team?
To get the dbglog from SA520W, login through web UI and in the browser enter the following URL:
https://LAN_IP_address_of_SA520W/scgi-bin/dbglog.cgi
These logs will store password, so please remove any password sensitive information. Also if you are not comfortable posting the dbglog on the community, you can send it directly to me through private message.
Cheers,
Julio
