CSS 11500 Re-balance services after service failure

We have 3 servers in our server farm and under normal circumstances wish to balance them unevenly such that the 3rd server only gets a small proportion of the traffic. The other two should be equally balanced. (Say 45, 45, 10).
When one of the prime servers (1st or 2nd) fails we wish to distribute the load across the remaining 2 evenly.
We are currently considering a cmd-sched script which will monitor the status of all three servers and reset the weights in the case of a server failure.
Is there a better way, preferably without a cmd-sched script?

Andrew,
This is messy but it should work. Configure multiple services for each server. Then use keepalive scripts to make some of the server3 services show as down if both the other servers are up, but if one of server1 and server2 is down, then all the server3 services show as up. You need to end up with the same number of reals configured for each physical box and vary the scripts so that most of the server3 services are down when the other 2 servers are OK.

CSS 11500 Load balancing

Hello,
We have a CSS 11503 with the following partial config
==================
service 10.10.10.221-1724
ip address 10.10.10.1
keepalive type tcp
port 1724
keepalive port 1724
active
service 10.10.10.222-1724
ip address 10.10.10.1
keepalive type tcp
keepalive port 1724
port 1724
string string1
active
content 10.10.10.1-80-website
    vip address 10.10.10.1

    add service 10.10.10.222-1724
    port 80
    protocol tcp
    url "/*"
    active
============================
There is connectivity from CSS to both IP's, 10.10.10.221 and 10.10.10.222. Problem we face is as following:
A client can hit web site on both servers by going to http://10.10.10.221:1724 and http://10.10.10.222:1724.
With service started on 10.10.10.221 and 10.10.10.222, a client PC can hit website by using http://10.10.10.1.
With step 2 above, connection count increasing on "service 10.10.10.221-1724" service.
There is no activty on "service 10.10.10.222-1724"
When we stop services on 10.10.10.221, client can no longer access web site using http://10.10.10.1. In this situation, connection counter on "service 10.10.10.222-1724" increases with each attempt to access web site but the page on client machine times out.
With service stopped on 10.10.10.221, client can access web site using server IP, http://10.10.10.222:1724
Restarting service on 10.10.10.221 makes access to website usig http://10.10.10.1, load balancer IP.
When capturing packets using wireshark, we see that the client machine sends re-transmission on "HTTP Get" and evantually times out.
With behavior above, it is clear that the server at 10.10.10.222 is active. What we cannot understand is why web site is inaccessible thru load balancer using http://10.10.10.1.
Please help.
Thanks,
Paresh.

Hi Paresh,
To troubleshoot this, I would recommend doing a traffic capture on the server vlan to see what is really happening with the connection.
One thing worth checking would be comparing the routing configured on both servers. If the traffic back from the server towards the client is not going through the CSS, the connection would fail, with the exact symptoms you are describing.

Using a single CSS to load balance multiple services

Is it possible to use a single CSS to load balance 3 different services (server farm) ? That mean the CSS need to advertise 3 VIP
I'm thinking of two scenarios:
1 - configure the CSS to use 4 interfaces: 1 to public, 3 to private (each interface will plug-in to a different vlan/server farm)
2 - configure the CSS to use 2 interfaces: 1 to public, 1 to private (all 3 server farms are in the same vlan)
Will both scenarios work ?
Thanks
--Phillip.

Hi Phillip,
both scenarios will work. One CSS can certainly manage more than 3 services! You can even use just one VIP for all traffic, then just create the proper rules to send specific traffic to the corresponding service(s). No need for 3 VIPs.

Services with different IP address subnets over CSS 11500 series

Hi all folks!
I have two CSS 11500 series...
In just a few months i will have ready a DRS (Disaster Recovery Site), where i will have 2 more servers to add to the environment.
But this servers will be in a different subnet from that today i have for the servers who are configured in the current services of my CSS.
So then the doubt i arises is:
Is correct to add two new services with these servers, but using the IP addressing of the DRS site???, and including on the CSS a static route to this network, (of the DRS) in order to reach them?? is it correct, it will work well?
This would be so....

[CSS-A]-[CSS-B]                                                            [SWITCH]
       |          |                                                                     |         |

So, at [CSS-A] & B, i will put a static route to firewall that know the subnet of site B through the IPSEC tunnel.
So In the CSSs, i will add the new services for the Servers "D" & "E" with the IP address of Site B.
This should be seen as well:
!*************************** GLOBAL ***************************
ip route 0.0.0.0 0.0.0.0 [IP FIREWALL]
ip route SITE B [IP FIREWALL]
!************************** SERVICE **************************
service srvA
ip address A.A.A.x
port 8080
service srvB
ip address A.A.A.x+1
port 8080
service srvC
ip address A.A.A.x+2
port 8080
service srvD
ip address B.B.B.y
port 8080
service srvE
ip address B.B.B.y+1
port 8080
I know that this practice is not the most desirable, in fact should use"Basic Global Server Load Balancing Site Redundancy Using the CSS with DNS", but I don't have much time to change the entire environment today, and in this first stage i have to begin with this poor but quick solution that i thought and i wanted to be validated if there is posibliidades this to work
Within their experiences that they say? Will operate?
Thanks in advance!

Daniel!
Sorry by delay!
Thank you so much for you time for reply.
You have given me a great help to this doubt!
But..using "source group" let me know..
I can´t undertand the really difference between NAT with ACls as you can see at this link: (http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080093dfc.shtml)
and
this other link, using NAT (from the piont 5), (http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_configuration_example09186a0080093dff.shtml)
where the NAT is configured under a method different from the previous one..
So.. for this scenario described above, which would you recommend using? I would think that the second is the most indicated truth? What do you think?
Thanks in advance again!!!
Have nice day!
Regards.
Esteban.

Supplementary Service Error : System Failure

I am using Blackberry 8520 Curve mobile with Reliance GSM prepaid network in India.
I am unable to access the internet and facing problem, while checking balance inquiry that "Supplementary Service Error : System Failure".
Further, I would also like to register my mobile.
Looking forward for the tips to solve the problem.

Hello !
Firstly, SUPPLEMENTARY SERVICE ERROR, is not an error to be worried upon.
It is highlighted mostly after every call which You make it from your BlackBerry Smartphone.
Secondly for activating BIS, you need to contact your service provider.
Once activated, you'll get to see "EDGE" symbol on your homescreen, near network strength signals.
Hope this resolves your Problem!

No. I dont think you can load balance PPTP service behind CSS 11500.

CSS 11501 7.40 Monitoring the services on real servers?

Hi,
Just want to ask some basic questions, How can i monitor the services (ie 80 and 443) of the real servers. So that when the CSS11501 detects that one of the services of one of the real servers is down, it will not forward the traffic to that server. Or is the CSS is configured to monitor the services by default?
Because we are planning to upgrade one of the webservers (web01) while web02 is running, if we shutdown the service 80 and 443, does it affect the end-user, will CSS automatically redirect it to web02?
Regards,
Marlon

Is it possible to not pay ATT if I stopped using service after buying iPhon

I would like to buy iPhone 3Gs and I don't mind subscribing to ATT, but my concern is:
What if I didn't like iPhone & neither ATT service after buying it, *is it possible just to stop using both of them (iPhone & ATT) or I'll have to pay for 2 years no matter what happens?*
Its logical that if I didn't pay after 4-5 months, they can stop the service & iPhone will get locked again and that's all, isn't it?
Regards,
Alan

You can return an iPhone for payment credit within 30 days after the purchase date - less a 10% restocking fee, and cancel the contract with AT&T within the same time frame with no early contract termination fee charged by AT&T. If you cancel the contract after the initial 30 days, you will be charged an early contract termination fee by AT&T and you keep the iPhone. The iPhone will remain carrier locked with AT&T, and unless the iPhone remains activated with AT&T, you have no warranty coverage. The iPhone includes a one year warranty.
If you don't pay after 4-5 months and you ignore being contacted by AT&T about your past due balance, your service will be cancelled, AT&T would eventually turn this over to a collection agency, this would be reported to credit bureaus affecting your credit history. Go to get service with another carrier with a subsidized phone, and you will likely be forced to pay a deposit before being granted credit again with a post-paid account.
The iPhone is sold in the U.S. as carrier locked with AT&T only, and remains carrier locked with AT&T regardless if the iPhone remains activated with AT&T or not.

Help:Invoke web service after receiving a user task response

Hi, All:
We encountered a problem while developing user task. The detail is as follows:
We need to invoke a web service after a user task's response, that is to say, the web service needs some data from the response of the user task.
Take the loan flow tuturial as a example, what we need to do is to invoke a web service after the BPEL process get the start loan APR. the web service needs the APR for its input message. how can I handle this situation?
Thank you very much for your help!

Thanks for your immediate response Jan Vervecken.
I have created the Data Control from web Service proxy and I am able to recieve the output from the web Service.
But, Currently I am invoking the webservice process method by a command button which populates my SelectOneChoice.
My requirement is to invoke the web service 'process' method by value change event in the SelectOnechoice control.
So, Can you pls. let me know how do I bind the web Service method 'process' to value change event of SelectOnechoice control?
Thanks and Regards,

After servicing my laptop recently, I can no longer find the time machine back up disk

I recenty had my macbook pro serviced after the hard drive cable was broken. Upon return, when I attempt to back up to time machine it says backup disk not available and I cannot find any disks to select in time machine preferences. Any idea how to fix this?

aimehunter,
if you had Time Machine running without connecting an external drive directly to your MacBook Pro, then it must have been a wireless connection to an AirPort Time Capsule.
Open the Time Machine pane in System Preferences. Does it show that you have a destination drive selected there? If not, press the Select Disk… button to select your AirPort Time Capsule drive. After that, select Back Up Now from the Time Machine icon in your menu bar to restart your regular Time Machine backups.

Iphone 4 without service after IOS 5.1

I am without service after IOS 5.1. Since the upgrade, my phone can't make or receive any call. I bought it from my mobile operator (Claro Brasil) itself. The odd thing is that when I use the SIM of my brother (from another provider - TIM) the phone works perfectly. Please, can someone give me any advice. I called to Claro and they said everything is fine with my network and that they will open a procedure to see what can be done. I think they don't know what is happening and I can't wait much longer.
Thank you in advance.
Luis
Brazil

Yes, I tried to restore it as new. Actually, 2 times, with and without backup. Today I will try to get a new SIM. Hopefully, that will solve my problem, but I am a bit skeptical as my SIM was working ok before the update.
Thank you very much for your help.

Service PR amount is noyt reduced after Service PO creation in CJI5 report

Dear Experts,
When user created Service PO with T-code ME21, Service PR amount is not reduced from CJI5 report & also increased budget in CJ30.
But when user create PO with T-code ME21N, Service PR commitment is getting reduced after Service PO creation in CJI5.
Please explain & propose solution.
Thanks & Regards,
Arvind

Hiiii...
Note that there is no difference between creation of purchase order via the t.code ME21 or ME21N...what might be your problem in increase of assigned values is because the buyer (purchase dept) is not referencing the purchase requisition at the time of creation of purchase order as a result of which the system is not reducing the purchase requisition committment.
Hope this helps....

User profile service incremental sync failure

Hi all, I'm working for a client that has a failing UPS incremental sync. The scheduled sync was running fine until a couple of weeks ago when it suddenly stopped working. Coincidently, this was also at the same time that they noticed the incremental search

Other issues
When creating a new sync connection in CA, the following message is displayed when the connection is saved:
“Unable to process create message”
I also see this error message in the logs:
A update on the configuration of a MA or MV failed to replicate to a target connector directory that is capable of storing MA/MV configurations. As a result, the MA/MV configuration data in this connector directory is not up to date. Please correct
the condition that causes the error, and triggers a resync by updating the password information of the target MA. Additional information: Error Code: 0x80230709 Error Message: (The extension operation aborted due to an internal error in FIM Synchronization

The management agent appears in FIM, but isn’t displayed in SharePoint CA (UPS SA). At present we have a few test MA’s that appear in FIM but not in SharePoint CA (UPS SA).
I’m at a loss as to why this incremental sync has stopped working. It’s also strange that test sync connections are appearing in FIM despite error displayed in CA when provisioning them. Stranger sill, the test sync connections don’t appear in CA, but appear
in FIM.
Potential next steps include resetting the profile synchronization DB as detailed here http://technet.microsoft.com/en-us/library/ff681014(v=office.14).aspx#resetSync. If anyone has had any other suggestions, I’d be very grateful to hear about
them.
Many thanks

Try to start full sync,and if it also stop with the same error - try to reset Sync DB using this script:
$SyncDB = "<Sync DB name>"
$UserProfilesName = "<User Profile Service Application name>"
net stop sptimerv4
$SDB=Get-SPDatabase | where {$_.Name -eq $SyncDB}
$SDB.Unprovision()
$SDB.Status='Offline'
$UPS = Get-SPServiceApplication | where {$_.Displayname -eq $UserProfilesName }
$UPS.ResetSynchronizationMachine()
$UPS.ResetSynchronizationDatabase()
$SDB.Provision()
net start sptimerv4
