To Load Balance or Not to Load Balance? ISE and F5 Big IP

Currently my team is debating whether to put our two ISE appliances (PSN nodes) behind our F5 load balancing deployment.
Our network is relatively small in size (5K users) with a small wireless deployment (4 Cisco controllers with 300 Access points). Network growth should remain relatively minimal over the coming years.
We will be rolling out wired Dot1X, followed by posture assessment and remediation. (BYOD is not an option).
On one hand, the Big IP features could make it easier for us to perform load balancing, maintenance and troubleshooting.
On the other hand, the Big IP adds another element of complexity into an already complex deployment. We already have the capability to load balance from the switches themselves. Load balancing for wireless should not be an issue as our deployment is very small and I expect it to remain so. Given the size of my environment, there seems to be relatively little to gain for the additional effort and potential pitfalls.
Would anyone care to share their honest opinion on this issue?
Thanks,
Phill

Load balancers are elegant and do their job nicely when it comes to distributing the load between servers. You already have one so I would suggest using it if you have the technical expertise to configure it.
With that being said, if your team is not 100% comfortable with F5 then you should definitely skip it. Instead, you can configure your WLCs to use Node #1 as primary and Node #2 as secondary Radius server and then your Switches to use Node #2 as primary and Node#1 as secondary.
I hope this helps!
Thank you for rating helpful posts!

Video white balance levels not showing, so video effects and color editing won't work

I've watched white balance tutorials, and I tried clicking the dropper onto the viewer to change the color. But, in the gray box above it there are normally red green and blue lines, but I have nothing there. I think this is preventing any edits to my color balance, can anyone help?

Well, no offense, but you seriously should read the C4D help. That's normal specular shading behavior and it is uniform acroos the plane because you obviously haven't defined any scene lights and use the default viewport light. Read up on how to create materials and adjust there properties and then learn the fine art of scene lighting as well as how to use object buffers to isolate objects with multipass renders.

Value not udated in Balance tab of J1IH

Dear All,
Value of Excise Balance is not updated in balance tab of J1IH when i am doing other adjustment
please tell me what are the settings for the same
in quality it is working fine
thank you and hoping for the best respose
regards,
CA Maulik Maniyar

got the answer
this problem comes when we are doing back data punching and the open periods are not current periods. for example, the current period is Apr and if one of the open periods in MM is not April, then this problem arises.
i was facing a different problem, though the current period is open the balances are coming as negative. this typically happens when the open period is the first period in the new fiscal year and we didnt run the balance carryforward function in FI. Once that is done this problem will not arise.
thanks & regards

Loader Event.INIT fires but Loader.content is null

The title describes the problem: Loader.load() is firing the INIT event, but in my listener it's reporting loader.content as null. The description for INIT event is "Dispatched by the associated LoaderInfo object when the properties and methods of the loaded SWF file are accessible."
I'm loading a lot of JPG images, and 95 percent of the time it works fine; the init listener fires and reports valid loader.content. I absolutely need loader.content available because I need to set the bitmap smoothing property to true.
I've tried using Event.COMPLETE and it has the exact same problematic behavior.
Any ideas?

I didn't try contentLoaderInfo.content before. When the problem occurs, it throws this:
Error: Error #2099: The loading object is not sufficiently loaded to provide this information.
So INIT and COMPLETE fire, but it's not sufficiently loaded to even access the content? Weird.
Note that in the event handler, Event.currentTarget points to the contentLoaderInfo, which may have the "content" defined, while it's not yet defined on the Loader instance yet. But thatt's just a wild guess though.
Well what do you know, you're right. loader.content is null, loader.contentLoaderInfo.content is inaccessible, but event.currentTarget.content is available. I've tested around and sure enough, the same situations before where loader.content is null is now working fine with event.currentTarget.content -- I am able to cast the content as Bitmap, set smoothing to true, and resize the content.
Kinda buggy if you ask me, but glad it's working now and it makes think I should use currentTarget more than often as it's apparently more reliable, at least in this situation it was.

The load balancer is not provisioned error when attempting to deploy a SP 2013 App

Hello:
I am in VS 2013 with SP 2013 colocated on same Win 2008 R2 server. I opened a SP 2013 App and directly hit F5 and got this error:
Error occurred in deployment step 'Install app for SharePoint': The load balancer is not provisioned. Verify the load balancer was provisioned successfully before retrieving endpoint addresses. When creating the project, the first screen asks for a
site to deploy to, and I just took the default, which was http://<servername> for the colocated server.
I googled this and could not find a solution. Would anyone have any direction?
thank you
Harvey
Regards, Harvey

Hi Harvey Flaisher,
Based on the error message, this seems to be a service application not working issue.
Please check the ULS log or Event log to check in which service application the error occurs, like BCS, secure store service, app management service, then re-provision the service application using PowerShell command, or re-create the service application
from UI to check the result.
Thanks,

Oracle Applications 11i Load Balancing does not work with RAC one Node

Hi all,
Could you help me to resolve this issue.
Architecture environment is :
- One APPS tier node
- Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
- The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
Thank you for your advice.

This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

Load balancing is not happening on RAC (oracle 11g Rel 2) on Linux 5.1

Hi,
Load balancing is not happening on Oracle 11g RAC. We have defined the SCAN listener and confured the TNS accordingly. Still we get the load maximum on node2 and less load on Node1 or vice versa. Please suggest me what to do?

This is not the right forum to ask this question.

Load balancing is not working correctly during server fail-over

Hi,
          We have 4 weblogic instances in a cluster with proxy-plugin load balancing the requests. When instance 1 is shutdown, all the subsequent requests from users whose sessions were at instance1 are sent over to instance2 only. They are not divided between instance2, instance3 and instance4.
          Can somebody, please, tell if there is any solution to this so that sessions for users who were being redirected to instance1 will be divided between instances 2,3 and 4.
          Thanks,
          Prasad

It is not possible because in a cluster server1 always chooses the same secondary server (with some algorithm)
          So all sessions with primaries on server1 will have secondaries on same secondary server.
          So if primary is down, all the requests(that has primaries on server1) will be routed to the same secondary server.

GL - Balances do not match with sum of Items

Hi,
I have a requirement in which I am pulling opening, closing balance and a list of all transactions (or items ) on a daily basis from GL to a flat file, and then loading in a third-party tool . Now, the issue is sum of all items (gl_je_lines ) should match with the diference of closing and opening balances.
I reconcilied the items with Oracle's Journal Report. Items are matching.
I also confirmed that closing balance of previous day matches with the opening balance of current date.
But, ( closing balance ) - (opening balance) does not match with sum(items)
I am using gl_daily _balances for opening and closing balance.
Waiting for your inputs/suggestions..
Yogini

Hi,
Thanks for the reply.
I am not using GL_INTERFACE. The tables I am using for Daily balances are:
gl_daily_balances
gl_code_combinations
chart_of_accounts
And for the items, I am using gl_je_lines, gl_je_headers.
Also, I am interested in Entered Amount in GBP as the Functional Currency is GBP and there are many transacitons in different foreign currencies.
More updates : I found that I have calculate the Entered Amount in GBP from all Converted/Transferred/Entered amounts in different currencies.
So, I tried the following :
(Select Sum(end_of_date_balance)
from gl_daily_balances
where Currency_code = 'GBP'
and currency_type = 'U'
and accounting_date = sysdate -1 --Opening balance
MINUS
( Select Sum(end_of_date_balance)
from gl_daily_balances
where Currency_code = 'GBP'
and currency_type = 'C'
and accounting_date = sysdate -1 --Opening balance
This way, I got opening and closing balance, but still the differernce between opening and closing balance is not matching with the sum of Items.
Any suggestions / inputs are highly appreciated.

0x80230729 (The extension could not be loaded.)

Hi,
I've been working on this most of the day without any luck. I'm wondering if anyone has seen something like this.
PCNS can successfully deliver the password change to an AD target, so PCNS should be OK.
The failure occurs when we add the Oracle EBS Web Service management agent to the password sync targets.
The error message indicates that the Microsoft.IdentityManagement.WebService.MA.dll cannot be loaded due to an incorrect .NET framework version.
An unexpected error has occurred during a password set operation.

Forefront Identity Manager 4.1.2273.0"
I ran an Environment.Version command and it returns that we are using 4.0.30319.296.
In the dllhost.exe.config file, we have the settings:
<?xml version="1.0" encoding="UTF-16"?>

So, I think it looks like it should be trying to run the dll under the 4.0.30319 framework. The documentation says that framework is required and we are running it.
The dll is in the Extensions folder.
Has anyone seen this before or something like it? Any ideas on where else I could check?
Thanks,

Thank you for your reply. I've tried running in and out of proc with the same error showing up.
I tried a few different modifications to the miiserver.exe.config (as well as Mmsscrpt.exe.config and the Dllhost.exe.config files). I tried changing 4.0.30319 to 4.0 as per this article:
http://msdn.microsoft.com/en-us/library/w4atty68.aspx
Even though we are only on FIM R2 (not on SP1), I tried a variation on the config file changes recommended here:
http://support.microsoft.com/kb/2772429 but I referenced the newVersion as 4.0.1.0.
Still no luck.
Here's the miiserver.exe.config file. Maybe you'll see something glaringly wrong? Thank you for your help!

AR01 balance is not matching with FAGLL03 balance between the segments

Dear Consultants
I am facing one problem in Assets Reconciliation. I.e, the balance which is showing in AR01 report is not matching with FAGLL03 report for P & M Assets.
In my client I have two segment . 1000 and 2000.
As per that reports of both AR01 and FAGLL03 effect is as follows.
1.     GL value is showing more by Rs.54,13,516.34 with AR01 in 1000 segment in P &M at
                31.03.2009
2.     GL value is showing Less by Rs.54,13,516.34 with AR01 in 2000 segment in P & M at
                31.03.2009
After uploading the legacy balances as on 30.06.2008,
1.SAP Segmental Trail Balance has been tallied with Segmental Trial balance as 30.06.2008
2.Except this P & M balances, remaining all assets were tallied between FAGLL03 and
AR02 segment wise.
3.acquisitions during the year also tallied and Over all at company code level balance from 01.04.2008 to 31.03.2009 also tallied for all Assets including this P &M.
Cross check points:
1.I have checked the cost center , profit center and segments assignment u2013ok
2.I have tallied Profit center wise AR01 and FAGLL03. except, this P &M
3. No Manual Entries has been posted
So pls suggest me what could be possible reasons for this
any how. my client maintained the legacy system till 31.03.2009 along with SAP. now as per Oracle we are matching this values. so ,what I am thinking is ,to match the balances in P &M between the segments, Shall I post the JV between these gment? because , as on 31.03.2009 legachy value is matching with AR01 values.
--Only problem between Legacy value and GL Value.
--Depreciation not yet posted.
--client is ready to pass required adjustement entries after posting the depreciation as on 31.03.2009 to
match with legacy balance
--So ,I dont think it is not problem if post the manual entry in Asset GL to match the balance between legacy and Fagll03 report
--Over all Comapny code level plant and Machinery values is tallied with Legachy value
early reply will be very highly appreicated
Regards

Hello,
Run ABST2 to know the difference between GL and Asset Accounting.
Hope you must have reset the reconciliation accounts of assets OAMK and posted all the relevant GL asset balances. Note that initial asset balances loaded in AA will not automatically be transferred to GL. You need to pass the JVs.

For some unknown reason a down load was interrupted (not paused) and i have 1.7 GB of a 4.7 GB file down loaded. How to resume?

I was down loading a 4.7 GB file (ISO image) and paused at 1.7 GB. When resuming I got a message that the file could not be saved. On trying to resume the down load, it starts from the beginning! On checking the directory I find that a 1.7 GB file exists on my disk. How do I down load the balance file. The OS is Open SUSE 11.2. Linux.

In Disk Utility, select the iPod (the device) in the sidebar. So, if you see the iPod in the sidbar with a "volume" indented below the iPod, select the "device" (not the volume).
Go to the Erase tab to the right. The choice for Format is Mac OS Extended (Journaled). Name does not matter, because iTunes will rename it during the Restore. Click Erase.
it "flashed" out of itunes.
That may be an issue with the USB connection. As a test, shut down (power off) the Mac. Disconnect other USB devices including USB hub, except for standard USB keyboard and mouse (if normally used). SInce this is a laptop, connect it to its power adapter, so that it's not running on battery power.
Connect the iPod to a direct USB port on the Mac. Note if there is any difference regarding the iPod not maintaining a connection.
