BizTalk 2010 Load Balancing Not So Balanced

Ok here's our scenario.
1. One Orchestration running under HostInstanceProcess on 3 servers in the same Groupe using 3 different domain accounts
2. That Orchestration has a reference to Utilities dll, which in turns calls a stored procedure using ADO.net code
3. We run that orchestration, it gets around 2000 de-batched messages and for those 2000 messages it calls that ADO.net code
4. Back in that database we run sp_who to check how many connections are made from each machine, and we find that over 60% connections are always made from one particular BizTalk machine and it's not one off, I've seen it atleast 7 to 8 times, that machine
always has most number of connections, for example if there are 120 connections in total, 80 connections are from Server 1 while rest from others.
5. We put a Max Pool connections in the connection string to 250 (default is 100) but that doesn't make any difference.
6. This interface is facing a lot of connection time outs from the database, hence this investigation is done
7. The same interface works perfectly fine on BizTalk 2006 R2, it's connecting to the same database (so can't be a database issue), it has 2 servers, which make almost same number of connections to the DB when I check with sp_who, so load balancing seems
to working as expected in BizTalk 2006 R2.
So my question, I know BizTalk is supposed to do load balancing in a round robin fashion which should equally distribute the load but in my example in BizTalk 2010, it's not doing that clearly, it's overloading one server with almost 70% of the requests,
what could be the reason for this? Host instances are set-up similarly in all servers. Any help greatly appreciated.
Regards
Syed

BizTalk load balancing works in Round Robin fashion only for the new messages, while in case of instance subscription message will be routed to server holding dehydrated orchestration instance.
So the server having dehydrated instances will receive the correlated response along with the new incoming message.
So you can see one server slightly overloaded.

Load Balancing not happening

Hi Group,
We have to portal server instances installed on two different solaris machines.Infront of this sitting 4 WebSEAL boxes.Now some times when a user runns certain scripts to log on to the portal, we have huge number of sessions getting creted on one of the portal servers and the load is not getting balanced.Can any body let me know why does this happen?Has it got anything to do with the portal server or the way web seals route the requests to the portal server?

Biztalk: Server load balancing

Hi,
We have 2 biztalk servers in the group. For past few days CPU usage on one server was comparatively very high as compared to other. First server was showing around 60% of CPU usage while second one was reporting 12 %.
Today I just started to stop every host instance on the first server in order to find out the process resulting in high |CPU usage. It came to BizApp.. Host assigned for processing orchestrations.
At first I could'nt understand the reason why first server was taking all the load while second one wsa comparatively free. But to my surprise once I restarted the host instance on first server, CPU usage dropped to 8% for the first one.
I could not understand the reason behind this? It would be really helpful if anybody can give me a clue about it.
Thanks in advance.Shady

Hi Shady,
How is your environment set up? I assume you have multiple hosts setup for receiving, sending and processing. Hosts running the receive handler for the HTTP,
SOAP, and BizTalk Message Queuing (MSMQT) adapters require a load-balancing mechanism such as Network Load Balancing (NLB) to provide high availability. Host cluster support is provided to support high availability for integrated BizTalk adapters that should not be run in multiple host instances simultaneously; such as the FTP receive handler or, under certain circumstances, the POP3 receive handler (http://msdn.microsoft.com/en-us/library/aa560059(BTS.20).aspx). Everything else just do not require any additional clustering or load-balancing mechanism because BizTalk Server automatically distributes workload across multiple computers through host instances, unless you have made changes to hosts themselves (throttling) (http://msdn.microsoft.com/en-us/library/aa559893(BTS.20).aspx).

Load balancing not happening on UDQ in weblogic 11g

Hi Team,
I have a 2 clusters with two managed servers each on different machines
Cluster A(On machine 1)
Managed server A (on machine 1)
Managed server B(on machine 2)
I have created 2 JMS servers
JMS Server A on Managed server A
JMS Server Bon Managed server B
and a JMS module on Cluster A
and JMS connection factory targeted on Cluster A and a uniform distributed queue targeted on JMS server A and JMS Server B
But load balancing is not happening only one managed server is loaded at a time.. Using weblogic 11(aka 10.2.3)
Tried disabling server affinity but it did not help ...Can any one please let me know how to fix this?

Hi,
When you say load is not balanced and reaching only one managed server.
I assume both the UDD's targets are reachable and are visible in JNDI tree ?
also , what kind of application is it - i,e is it clustered app that would be seen as consumers on each UDQ ?
take a look at the app and check if its clusterred . along with that also take a look at the number of consumers on UDQ instances.
Let me know what you find.

RV042 Load Balancing not working correctly?

We have an RV042 on firmware version 1.3.13.02 and 2 ISPs:
WAN1 = Telepacific T1
1.5Mbps down and 1.5Mbps up
WAN2 = AT&T U-Verse
12Mbps down and 5Mbps up
I have it set to Load Balance, Primary WAN = WAN2
Network Service Detection enabled, only pinging the Remote Host of 4.2.2.2 and set to Generate Log
Bandwidth is set to:
WAN1 = 1000Kbps upstream & downstream
WAN2 = 5040Kbps upstream & 12000Kbps downstream
It seems to pick WAN1 a lot of the time. Do I have something setup wrong?

Ok, so what do you recommend? To setup binding for ports important to direct over say… WAN1 (my fast access) shall I also keep the bandwidth management set up as is, example:
For me it’s confusing because this config appears to be clear to me that has to control traffic the way I want .
Thanks for your response.

BP Balance not showing correctly in Aging report

Good Day all B1 experts,
We are converting to SAP B1 for fiscal year 2010 and earlier today I have found a problem with BP balance on the AR side. Below is a summary of the problem:
Problem:
- For some BP, after I entered opening balances, their total outstanding AR balance was not reflected in the Aging report, nor can be found in the Opening Balance window (under System Initialization).
- However, A/R control General Ledger account is correct and ties to my Year End 2009 Financial Statements
Attempted Solution:
- I reentered the "missing" opening balance for those BP accounts. After entering the numbers, however, the Aging report shows a DOUBLED amount of the correct balance. And when I go check the Opening Balance window, the system is showing the correct BP balance (NOT Doubled).
- Now my A/R control General Ledger and Opening Balance General Ledger Account is out of balance as well. The difference equals to the amount I reentered.
Has anyone encountered similar problem before? I cannot think of anything I did to cause such mess. In any case, I am wondering if I need to use the Restore BP function.
Please provide me some guidance on this. Thanks!!!
BR,
Sunny

Good Morning Kerstin,
Thank you for the article. The version that we are using is 2007A (8.00.180) SP:00 PL:45
In the article, it mentioned about the Single Reconciliation Engine. Do you know if that tool comes along with previous upgrades, or we will have to download and install it?
Actually it seems for one of those problem BP accounts, the correct balance is reflecting on the Aging Report after an invoice was issued yesterday. However, its BP balance is still not correctly reflecting elsewhere (such as Incoming Payment under banking module.)

Sunny

How to find option that upload mode u201CCreate opening balanceu201D?
i'm use to customize infopackage. i can not use default infopackage, when i click the defualt infopackage, will error prompt: Data target '0DF_C07' removed from list of loadable targets; not loadable

Quesiton: I donu2019t know whatu2019s version, neither like BW 7.X nor like BW 3.X,
Why have infosource in BW 7.X, how to use infosource load data to target?
Currently, I canu2019t create transfer rule and upate rule for this datasource & infosource.
Do I need to create a customize ODS?
Thank you very much , if you will answer me above two questions.

You don't need to worry about 0DF_C07 as it was defence cube not activated during your Business Content Activaiton.
YOu can create your own infopackage for 2LIS_03_BX and there will be option generate intial status.
This loading will create your Opening Balance.
you need to compress this with NO Marker UPDATE option unchecked(as you will have to update hte marker).
After this load movements 2LIS_03_BF and reval 2LIS_03_UM. Compress this with NO MARKER UPDATE option checked.

and "Reservation amount is greater than the balance in the bond!"(warning)
I checked the balance in bond it is really less but my client some times creating ARE1 document with negative bond balance because of delay in proof of export document for previous ARE1 documents and now we are implemening the ARE1 generation through sap.

Balance not matching as per FBL5n and FS10N

When we run the customer balance report FBL5n as on 09/29/2007 on week end it shown a balance ( open item for all customer and recon account 123456 ) of say 10 M. The same amount we got thru FS10N we ran on with GL 123456 i.e. 10M. But when we ran the report FBL5n today ( with same parameter 9/29/07 and recon account 123456, open items ) we are getting a balance of 13M but our GL balance is still 10M on 9/29/07. Here is my question why the balance has changed for FBL5N when I am running the report on past date ? I feel it should not. But say there is difference in these two reports, how to reconcile ?
My problem is I took the balance from FS10N and now I want details of that balance ( customer wise balance ) as on 9/29 . This should match and I need it for auditor .Kindly help me gurus.
Thanks
Satya

Satya,
The possible diffrence between FBL5N reports run on first time and second time might be.
There may be invoices posted to that Customer Accounts with past Posting Date after you took first Report.
To find out which invoice are posted after you run the report , run FBL5N again with the same parameters and select Entry Date column from the layout and sort it out. If you find some invoices where the Entry Date is past the Date you ran the first Report then these are the invoices which are contributing the diffrences.
Generally this will happen when Sales/Billing documents are released later to Accounting.
Thanks

POSTING ERROR-MESSAGE POSTING BALANCE NOT CLEARED FOR THE PERIOD 2/2008A

Hi
I have a problem in payroll posting. While posting for one employee's persn number rejected and gave a message as Posting Balance not cleared for the period 2/2008A. To come out of the problem I changed the Payroll status record using pu03 changed the Erliest Retro date as 01.06.2008. Again tried to post but not posted again same Message displayed. After changing the Erliest Retro record I have not run the payroll for the particular employee. Is it required to run the payroll for the employee after changing the status in PU03. Request to guide on this
Thanks
EKP Yadav

Hi there
The posting may be out of balance for the employee because their credits dont equal their debits...
Do a test posting for the employee with the log on, this will tell you what amounts are being posted - and should give you an inidcation of where the balance is not cleared...
Yes, you would have to re-run the employee if you'd changed the retro date in PU03, but I dont think that will fix your posting problem....Should the employee have retroe'd?
From what I have seen, just changing the control record doesn't usually fix an out-of balance..there is usually another reason....eg wagetype incorrectly posting to the wrong number of accounts....or a missing wagetype on the employee (eg bank details...no /559 for the net pay to go to).
Cheers

EBS Closing balance not matching with opening balance.

Hi,
The Scenario: The first file for EBS is uploaded. The Second file opening balance did not match with the first files closing balance.
As per my understanding the system throws an information message that FB729 that the closing balance did not match with the opening balance. The docuemnts also gets posted
Question: If the bank sends the corrected file after uploading the first error statement how will we update the corrected account statement with appropriate opening balace.
Thanks,
Raja.

Hi Taro,
             Thanks for your reply. Infact Initially I was of the same opinion that if there is inconsistency in the closing and opening balance SAP would not process the statement. Thanks for your investigation the sysytem is behaving differently for different formats.
               The SAP note 947857 only deals with a particular scenario where there is no inconsistency between closing balance and opening balance but the error comes up.
               I will try to explain why I am asking about a functionality which updates the opening and closing balances of a statement based on our past experiences:
                If we receive a wrong statement with wrong opening balance from the bank it would take us two weeks to convince the bank about the wrong opening balance and subsequently bank sending the corrected account statement. If the FB729 message is an error message then there is no option but to wait till two weeks to upload the next statements.
               So I want SAP to upload the wrong statement and the subsequent statements as they come form bank. To correct the opening and closing balances i want to check if there is some statndard functionality which can do this. Rather than Table update as you suggested I would prefer a custom program for this functionality if standard does not allow.
                If the difference between closing and opening balance is due to a missing statement then SAP has suggested a note "SAP Note 1025077 - Problem with uploading out-of-sequence BAI2 bank statement" which actually allows the out of sequence statements to be uploaded.
                 Finally I would prefer the option of the wrong statements to be uploaded into SAP in the order they have come from the bank and subsequent corrections to the statements as approved by the bank.
Thanks,
Raja.

Trail balance(FGI3) and G/L balance not tally (FBL3N)

Hi Experts,
I have a problem. My trail balance(FGI3) and G/L balance not tally (FBL3N). Please give me suggestion for checking this.
Thanks & Regards,
Hemant Maurya

Hi,
Now you are getting differences of balances for p/l accounts or balance sheet accounts.
For P/L accounts at every year balance carryforward to Profit and loss account. But you check the balances through T.code FBL3N you will get cummumlative balance. So better check the balance with T.code FAGLB03.
If the problem with balance sheet then just test carryforward balances to new fiscal year once again in test run so that you will come to know if there is any difference in value.

Balance not carried forward when changing fiscal year in Report Painters

Hello guys,
Im using report painter (FGI3) to create my financial statement report, when i change to fiscal year 2009, the balance in my balance sheet is not carried forward to year 2009, its only shows the the movement.
Assume, the total asset in dec 2008 is 10million, transaction in januari is -900.000,
the total asset in januari 2009 should be 9.1 million, but it only shows -900.000
Sorry my english not so good
Anyone can help..
Thanks.
Edited by: rama dazkia on Feb 2, 2009 3:16 AM

Thanks for the reply,
I've already doin the year-end activities, if i see the balance in F.01 it is correct
but in my report painters especially in january 2009, it only shows the difference
FYI, i using report painters FGI3, FGI5
Thank you

OINM not balancing to trial balance (JDT1)

I have written a report that produces sales and purchases per item from the OINM table using the InQty, OutQty and Price fields. The quantities are 100% correct but if I compare the total sales figure to the trial balance figures I get different results. It balanced for the previous month but is out for this month.
My question: Can the OINM table be used to accurately calculate the sales and purchases figure? If so, what is the best way?
The scenario that seems to cause my figures not to balance is the following:
A delivery is done at zero value and then invoiced at the correct value. This transaction sometimes reflects at a zero price on the delivery and invoice transaction in the OINM table, causing my report not to balance.
Any help will be much appreciated.

In your case, I don't think there are any ways to get the correct balance through this table. You may only get those right total through financial transactions, i.e. A/R ans A/P tables.
Thanks,
Gordon
