GSS act as an authoritative DNS for non-load balanced sites?

I have a client asking if a GSS can be the authoritative DNS server for their entire domain. This would include sites that are not load balanced.
TIA,
Dan

Hi Dan,
Yes, you would just have to create a new domain under the Domain Lists, create an Answer Group associated to that domain and then you can start adding DNS answers. For non-load balanced sites you would just have one answer in your answer group.
Sincerely,
Kyle

Best way for HTTP load balancing in OSB

Hi everybody,
We have setup an OSB cluster and we need to load balance HTTP requests across managed servers. Looking for info about load balancing in OSB I found that there are mainly two options: using a hardware load balancer or a software solution like Weblogic HttpClusterServlet. At the moment we have no hardware balancer available so we will have to take the software option. I found some articles about configuring HttpClusterServlet like http://redstack.wordpress.com/2010/12/20/using-weblogic-as-a-load-balancer.
But I have a question about this configuration. If we use a managed server as an HTTP proxy that balances requests between OSB managed servers, what would happen if this server goes down? I think one of the main goals of a clustered deployment is avoiding a single point of failure but with that setup all requests would depend on the availability of the proxy managed server.
Could you recommend us a setup for implementing load balancing in OSB?
Thank you in advance,
Daniel.

Load balancing in a cluster for http requests can be achieved using atleast 4 different ways:
(1)- use a hardware load balancer like F5 BigIP LTM
(2)- use a web server with weblogic plugin to frontend the cluster
(3)- use weblogic with HTTPClusterServlet
(4)- use DNS round robin - this works if you have managed servers running on 2 machines (say mach1, mach2) but on the same port. HTTP clients use hostname 'mach' to access the URL's and the dns does a round robin name resolution of mach to mach 1 and mach2 IP addresses..
All the options except (1) achieve only load balancing and not auto failover on all instances.. Hardware load balancers has the extra feature of probing [ sending periodic pings to the targets] , by which it can detect whether the target resource is alive and if not send the traffic to other nodes which are alive.. this is why hardware load balancers are worth their investment..
other options may work if client is coded to do retrying on failure.. so on 2nd or subsequent attempt, the routing is done to the machine which is alive..
For options (1),(2) and (3), you also need some redundancy of load balancing device ( web server, weblogic or hardware load balancer) to prevent single point of failure.. Hardware load balancers are usually deployed in redundant pairs to achieve this..

Timeouts on non load balanced traffic thru ACE

I have a backend server creating a connection to a db server outside the ACE environment. This traffic is using the L3 function of the ACE and is not being load balanced. The connection is timing out after 1 hour. I have normalization disabled on the backend server VLAN but not on the front side VLAN of the ACE.
2 Questions:
- With normalization disabled do I still need to change the tcp inactivity timeout for this traffic? Or with normalization disabled shouldn't the non load balanced traffic be L3 routed and not effected by the tcp timeout value?
- Also do I need to disable normalization on the front side VLAN of the ACE?
thanks,
kurt

As per
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/security/guide/tcpipnrm.html#wp1075741
"Disabling TCP normalization affects only Layer 4 traffic. TCP normalization is always enabled for Layer 7 traffic."
By disabling TCP normalization the following Layer 4 connection parameters are ignored.
exceed-mss-----Configure behavior if a packet exceeds MSS
random-seq-num-disable----Disable TCP sequence number randomization
reserved-bits-----Configure Reserved bits in TCP header
syn-data-----Configure behavior for a SYN packet containing data
tcp-options-----Configure TCP header options
urgent-flag-----Allow/Clear Urgent flag
I think you will need "Set timeout inactivity xxxx" command even if "no normalization" command is defined.

SUNW.gds for jboss + Load Balancing Group = Failed to connect to host ...

Hi all!
In a simple two node cluster (Solaris cluster 3.2) with quorum server I've created a resource for jboss 5.1.0 using SUNW.gds. It is supposed to be load-balanced. To achieve that I've followed instructions from [http://download.oracle.com/docs/cd/E18728_01/html/821-1258/gds-25.html]
The command I've used to create the resource was:
clresource create -g scalable-rg -t SUNW.gds -p resource_dependencies=vip -p Scalable=TRUE -p Start_timeout=400 -p Stop_timeout=400 -p Probe_timeout=30 -p Port_list=8080/tcp -p Start_command="/opt/jboss-5.1.0.GA/bin/run.sh -b 0.0.0.0" -p Child_mon_level=0 -p Failover_enabled=TRUE -p Stop_signal=15 -p Load_balancing_policy=LB_STICKY_WILD jboss-rs
The whole configuration seems to work, but when the second node joins cluster, resource with jboss can't bind to shared ip address. There are many entries in /var/adm/messages like:
Jan 19 13:46:35 play SC[,SUNW.gds:6,scalable-rg,jboss-rs,gds_svc_start]: [ID 141062 daemon.error] Failed to connect to host vip and port 8080: Connection refused.

However, after some time, it finally somehow binds to shared ip and port 8080.
Is this something I should be worried about? Or it is a normal thing, since e.g. it takes some time to bring the interface with shared ip up? I've never had to install such configuration, and I don't have neither intuiton, nor the experience. Any help would be very appreciated.
Thanks a bunch,
Bart

Hi, a couple of things to check:
- did you check that both JBOSS instances were up and running?
- can you check in the logs (on both nodes) when a message saying something like "service .... registered..." showed up. This should show up for both JBOSS instances. From the time of the second "registered" message, the load balancer should sending incoming requests to both instances using its distribution mechanism
- did you check the vip address on one of the nodes on an external interface and on lo0 on the other
- connection refused looks like a server problem; can you connect to the JBOSS instance locally?

Not able to find mod_oc4j.conf file for setting Load Balancing on ESB

Hi Guys,
I am trying to set load balancing on ESB ,I got one document from oracle site for setting the load balancing on ESB. According to that document we have to change mod_oc4j.conf file for setting the roundrobin:weighted,metric,random algorithms.
But I am not able to find mod_oc4j.conf file in my ORACLE_HOME directory.
Actual path is
ORACLE_HOME/Apache/Apache/conf/mod_oc4j.conf file
I have All folders up to conf but in conf folder there is no mod_oc4j.conf file.
I just want to know is there any installation problem or we have to create
mod_oc4j.conf file in that conf folder for seting the loadbalancing on ESB
kindly give me the exact solution on this .
Thanks in advance

Hi Chintan,
I have apache folder ,but there i have cong folder but in that I am not able to find mod_oc4j ,I know ESB it maintain load in transparent way but in my project we have heavy load on ESB we have to maintain this load in a proper way
Please give me the exact solution to set load balancing On ESB.
Thank you

Geting IP address for Internal Load Balancer

I've recently been experimenting with internal load balancing for VMs. I'm able to create and delete an internal load balancer (ILB) using the .NET wrapper for the API (https://github.com/Azure/azure-sdk-for-net). What I cannot do though is actually
get the internal address for it. Nor does it seem you can get it from the REST API (which, as far as I know, is what .NET wrapper wraps). The only method I can see that claims to get the address is Powershell.
Can anyone confirm if there is any way using the REST API or its .NET wrapper to obtain the internal address for the ILB?

I have not looked into the .NET wrapper that you mentioned here, but according to this powershell script:
http://msdn.microsoft.com/en-us/library/azure/dn690125.aspx
$svc="<Cloud Service Name>"
$ilb="<Name of your ILB instance>"
$subnet="<Name of the subnet within your virtual network-optional>"
$IP="<The IPv4 address to use on the subnet-optional>"
Add-AzureInternalLoadBalancer -ServiceName $svc -InternalLoadBalancerName $ilb –SubnetName $subnet –StaticVNetIPAddress $IP
IP address is optional, so maybe the wrapper hasn't implemented this, which is kind of undesirable. But maybe it allows you to specify the IP?

Forms Services availability checking for BIGIP Load Balancer

We are load balancing across a number of 10.1.2.2 Forms servers using a BIGIP load balancer. Currently our load balancing is done based on which server has the "least connections" to the BIGIP. So far we have been using the following test URL to allow BIGIP to check the availability of the Forms Services on each server.
http://server:port/forms/frmservlet?ifcmd=status
This works well however it only checks through to the HTTP level within Forms Services. We encountered a problem when the Forms Services failed to work on a particular server however the above URL showed that everything was OK. The effect of this was that all new users attempting to login were directed to the failed server as this server had the "least number of connections".
After raising an SR with Oracle they advised that the forking of runtime processes had probably failed and this was not detectable by the load balancer with the above URL. So they have recommended a number of options for checking the status of the Forms Services. These are:
a) http://server:port/forms/frmservlet
This loads the default Form and therefore by definition tests the forking of runtime processes. However BIGIP is unable to automatically process the information to distinguish whether the service is up or down. Oracle recommended that if using this method we would need to customise BIGIP to handle the various FRM-xxxx error codes.
b) http://server:port/forms/frmservlet?userid=scott/tiger@YOURDB&form=yourtestform.
fmx
Even more thorough would be to actual log on to the database using a test form as above.
My question is does anyone out there have experience in checking Forms Services availability using these last two methods as I'm not sure how to customize the load balancer so that it can handle the output of these URLs. Also when using the original URL is it normal to load balance using a "least connections" method or do people out there use a different algorithm.
Thanks for any help/advise that you can give.
Regards,
Philippe

Well SR followed up and it looks like the only course of action is to use the standard HTTP check: http://server:port/forms/frmservlet?ifcmd=status ...
... unless that is you want to do some serious customisation. Oracle don't support any other form of checking.
I'm guessing from the lack of responses to this thread that this hasn't been an issue for anybody else ... ???
Any thoughts/suggestions really welcome as we go into production in 4 weeks.
a) What do people recommend for load balancing Forms ... least connection, round robin ... ?
b) Do people use http://server:port/forms/frmservlet?ifcmd=status or have some of you used something else?
Thanks,
Philippe

Question on WCCPv2 - bucket assignment for WCCP2 load balancing

Hello,
I would like to know if any one has tried out running Cisco's WAAS/WAFS/WAE or
Squid proxy as a cache cluster to leverage load balancing support in WCCPv2.
I am trying to understand WCCP based transparent network redirection in a lab setup using squid cache's WCCP and Cisco routers only. When I tried with 2 proxies for load balancing, I see that the router *always* allocates buckets in the reverse order of the specified assignment - its confusing as its not mentioned in Cisco WCCP2 protocol drafts.
In my case, the lead cache with the lowest IP specifies buckets 0-127 to itself and 128-255 to the other; but the router assigns buckets 0-127 to the second cache and 128-255 to lead cache.
I have attached the ethereal trace. Can someone explain what is going wrong here?
The issue was found in the following router versions:
Cisco 3600, IOS 12.3(1a);
Cisco 2600 IOS 12.3(9a);
Cisco 2800 IOS 12.4(3d)
Squid proxy:
2.5
WCCP status output - all the routers above show the same behavior.
From the trace, 192,168.8.231 specifies bucket distribution as its the
lead cache with a lower IP than 192.168.41.232.

I'm not an expert of the details of wccp, but looks like the squid is not setting the bucket info correctly.
From the draft [below], the first bit is the the A flag - for alternative hashing.
And the alternative hashing is determined by another flag in the service info.
So, why is Squid setting this bit ?
I feel like they forgot to shift the index by 1 bit to the left.
Bucket 0-255
Contents of the Redirection Hash Table. The content of each bucket is a
web-cache index value in the range 0-31. If set the A flag indicates
that alternative hashing should be used for this web-cache. The value
0xFF indicates no web-cache has been assigned to the bucket.
0 1 2 3 4 5 6 7
+-+-+-+-+-+-+-+-+
| Index |A|
+-+-+-+-+-+-+-+-+
I'm double checking with a developpers for our cache, but I feel like this is the explanation.
More info to come if I'm wrong.

Coherence Extend Address-provider for dynamic load balancing

Hi,
I want to have load balancing across my proxies. so, trying to use <address-provider> feature.
Here is my setup,
I have two proxies and many clients.I am configuring both proxy and the client to use load sharing scheme.
There are implemented classes for the interface AddressProvider. So, i am going to use that.
Here is proxy server settings,
<proxy-scheme>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>10</thread-count>
<acceptor-config>
<tcp-acceptor>
<address-provider>

</address-provider>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>

Cannot start daemon
First question:
1) without address provider section in the proxy server configuration xml, will it use any default address provider implementation?
2) what's wrong with the proxy server settings xml which causes above error?
Thanks
Prab

Hi LuK,
Sounds like there is no load balancing is happening in my environment.
I didn't use address provider tag since it's mentioned in AddressProvider Interface API that by default it uses ConfigurableAddressProvider implementation.
Here is a xml snippet in remote client cache configuration xml,
<tcp-initiator>
*<remote-addresses>*
*<socket-address>*
*<address>PROXY-A</address>*
*<port>9099</port>*
*</socket-address>*
*<socket-address>*
*<address>PROXY-B</address>*
*<port>9099</port>*
*</socket-address>*
*</remote-addresses>*
<connect-timeout>10s</connect-timeout>
</tcp-initiator>
what i mean by load balancing is,
I will be having lot of web service queries which runs very fast. I would like to see both the proxies serves the web requests.
I am observing, One connection has been made to one proxy when it's starts up and keep hold on to it (no matter whether other proxy is free or not).
is it a bug? or am i doing some mistake?
Thanks

Azure: "Cloud Services" for VM - Load Balancing, yes, and other things?

I'm trying to get a handle on the significance of the cloud service
(that is created when a new VM is created). I understand that a group of
VMs need to belong to the same cloud service in order to participate in
Load Balancing. I can't see any other reason to group VMs into a single
Cloud Service. On the other hand it seems like overkill to create a
cloud service for each VM.
Are there any advantages/reasons to adding a group of VMs to Cloud Service other than Load Balancing?

Hi,
If you made a group VMs as a cloud service, you can configure them and manage them by yourself, you could select Linux or Windows Server VMs and either compose the VM images in the cloud or upload a VHD you’re previously
created using Hyper-V, You can capture a VM and add it your image gallery for easy reuse. you also could run a product like Active Directory or SQL Server or SharePoint Server successfully, etc...
I suggest you have a look at following article. (create VM as cloud service belong to IaaS)

Does GSS have to assume authoritative role for the entire domain?

We'd like deploy GSLB for a critical application between two datacenters.
From reading through a few documents, it appears the GSS needs to be the authoritative name server for a zone/domain?
Is it possible for the GSS to only answer DNS queries for a few (or a single) VIP's?
For example, is it possible for GSS to only handle queries for app1.abc.com, instead of the entire abc.com?
Or do we have to create a new sub-domain, such as glb.abc.com, and change the application's FQDN to app1.glb.abc.com?
thx,
Kevin

You can make the GSS authoritative for a few vip's or services if you like. You will need to tell dns to delegate the subdomains or services to the GSS.

Using iWeb for non dot-mac sites

Hi all,
I own a number of domains that I'd like to use iWeb on. Am I able to utilize iWeb for a non .mac domain, or do I need to use something like Dreamweaver?
Many thanks.
-Hugh

No, in fact I have a sneaky suspicion that not using dot-mac sites will eliminate a lot of problems other people have. You will also lose some of the effects like the nicer slideshow etc.
I have never used dot-mac and never encountered any of the uploading/publishing problems that are so often mentioned on this forum.
Here is what you do:
After editing your website you choose :Publish to a folder.
This lets you choose a location on your hardrive into which all the necessary files will be compiled/rendered. In this folder you will find an htlm file plus a folder with the necessary files for easch of your pages.. This publishing is done lightning fasy pecause it is done locallly and not trhough your internetconnection like when you published to dot-mac. Also post-editing is easy and hassle free.
For editing and uploading my website I use "Transmit" but there are lots of other applications like "Fetch"
What to upload?
Well I believe the jury is still out on this.
I just upload the contents of the published folder and that works for me. Other publish the whole folder plus the dummy "Index file" that is generated outside that folder. You will heve to find out for your self.
If any changes or editing has to be done afterwards, I republish and then just upload the altered files.
There is one more thing I do, and I believe others don't. I keep my domain file in the same folder where I keep the Published folder.
E.g. there is a festival website, so I have a folder "Festival" in which I keep the domains file, and the published "Festival website" folder.
This way it is easy to keep various different websites.
When you want to edit one of them, go to that folder and double click the domains file, this will start iWeb with the right website for you to edit.
Really very easy.

CMS for non-CMS HTML sites

There are lots of nice, attractive HTML templates out there for purchase that can deployed quickly for sites such as restaurants, cafes and the like. While I usually use Joomla and Wordpress exclusively, I wouldn't mind using some of these simple HTML templates simply because there are a lot of them and that gives me more choices. Moreover, they usually come as responsive templates nowadays so you get to charge the client for that without having to install an extension to create a mobile site (even though that's not really more than a five-minute operation).
Since I always market my sites by offering both a Content Managment System and a Responsive Design, I don't want to put myself in a box by having to use Joomla and Wordpress when I could just as easily install a little CMS for basic editing of text and images.
In the past I have always found security to be an issue with these budget CMS, so this would have to be resolved before I would be willing to use one.

Can a single instance of iPlanet Web Proxy act as a reverse proxy for multiple internal web sites?

Hi Dave,
You should be able to create multiple reverse mappings.

Help for ACE load balancing process

Hi All,
how servers behind ACE can access a VIP on the unit/context
the scneraio is this:
10.51.72.247 --> 204.110.71.140 --> 10.51.70.41
as you can see it is traffic within same ACE context
could you please share the document for the same ?
Thanks in advance,
Reg
Mohamed.

Hope you are doing well!
Since you are having issues with ACE, Have you considered using Citrix Netscaler with Cisco RISE Integration. I wanted to mention this new feature Automated Policy based Routing(APBR) and RISE(Remote Integrated Service Engine) that is available on Citrix NetScaler which might ease you pain points in configuring services and provides signification OPEX and CAPEX savings when used with a Nexus Series Switches like Nexus 7000.
Here are some details and links
RISE (Remote Integrated Services Engine) is an innovative, industry-first architecture conceived by the Nexus Services engineering team to seamlessly integrate Nexus switches with appliances offering L2/L3/L4-L7 services. RISE makes the service appliance look like a line card in the Nexus 7K series. This integration allows any appliance to take advantage of the benefits of an in-chassis module such as increased application performance, high application availability, and data center consolidation.
