Load Distribution Versus Parallel Jobs processing

Hello,
I would request feedback.
In Industry Solutions - PS, for mass activity - Automatic Clearing run, there is an Technical Settings tab.
This tab has Load distribution settings and an value that can be defined for Number of Jobs.
If I put an value greater than 1, so many number of jobs gets executed in the background.
I would request clarification on the following :
1. What is its use / benefits of putting defining an automatic load distribution ?
2. Does this setting equals the Config settings for IMG - Finnancial Accounting- Contract AR - Technical Settings - Prepare Mass.
In here, we can set parallel jobs that can be initiated by providing an maximum number of jobs under the job control panel.
Does this setting override Load distribution settings or vice-versa OR IS this an different setting ?
3. What is the difference between Load distribution versus parallel Jobs ?
Any feedback, most welcome and appreciated.
I am functional consultant and hence unable to distinguish between the two.
I am not sure if this query needs to be posted here, but I have also posted the same in IS fourm too.
Regards

Hi Bala,
In any Mass Activity you will find Technical Settings tab. There you will find Parallel Processing Object and Load Distribution. In Parallel Processing Object, you can select object according to Input depending upon which you will able to divide the job. For example, GPART is used when job have to divide depending upon Business partner. In Maintain Variants you have to create Variants.You have to give Variant name and value in either Interval length or Number of Intervals. Interval length will decide what is the maximum number of object will be processed in a single part. Number of Interval is the number which tells job will be divided in how many parallel process.
For example, let you r running a parallel process for 1000 Business Partner.You choose GPART as object.Now if you put 200 in interval length it will divide job in 5 parallel process.If you put 10 in number of interval it will divide the job in 10 parallel process each of 100 Business partner.
After creating variant, you use it in technical setting.
Let u already define variants which divide the job in 30 but you want maximum number of parallel process will be executed at a time is 6.Then put 6 in Number of jobs field in automatic load distribution.
Hope this can able to clear your question. Still if have any doubt feel free to ask me.
Thanks and regards,

Query to Report on Parallel Jobs Running

Morning!
I would like to get a query that reports on my parallel jobs.
For each minute that a procedure is running I would like to know what stages are running.
I log the whole procedure in a table called run_details and the start and end of each stage in a table called incident.
I'm running Oracle 9i
Here is some sample data based on 2 threads Expected output at the bottom

Thank you for your time.

> Ideally I'd like this to work for n-threads, as I want this to run on
different environments that have different numbers of CPUs.
The number of CPUs are not always a good indication of the processing load that a platform can take - especially when the processing load involves a lot of I/O.
You can have 99% CPU idle time with a 1000 active processes... as that idle time is in fact CPU time spend waiting on I/O completion. Courtesy of a severely strained I/O channel that is the bottleneck.
Another factor is memory (resources). You for example have 4 CPUs with 8GB physical memory.. where a single process (typically a Java VM for a complex process) grabs a huge amount of memory. Assuming that 4 threads/CPU or 1 threads/CPU can be a severe overestimate due to the amount of memory needed. Getting this wrong leads in turn to excessive virtual memory paging and reduces the platform's performance drastically.
CPU alone is a very poor choice when deciding on the platform's capacity to run parallel processes.

How to increase parallel jobs for TA SGEN

Hi all,
we did an SGEN load for an AIX ApplServer and a LinuxAppServer to know, which load has a longer runtime.
We saw, that the linux server has more than twice than the AIX server ... But we also noticed in joblog, that
AIX had 37 parallel jobs for sgen und linux only 20 ...
I don't know, where to configure, that linux also uses 37 parallel jobs for sgen ...
I found an notice in help.sap, that perhaps TA rz12 could help me, but how !?
Kind regards
Andreas

Hi,
SGEN uses the configured quota for asynchronous RFC. Do the following:
RZ12 => select group "parallel_generators" (probably the group already exists, otherwise create it and assign to the instance(s) you wish to participate in this group)
For each instance that is a member of the parallel_generators group:
- Double-click on the entry
- The relevant quota are "Max. Number of WPs Used (%)" and "Minimum Number of Free WPs". The first is treated as a percentage of the number of DIA processes. The second indicates how many DIA processes must be kept free.
Save the changes you make.
Example: assume that an instance has 20 DIA processes and you configure "Max. Number of WPs Used (%)" = 50 and "Minimum Number of Free WPs" = 5. This means that SGEN will start 10 parallel jobs (50% of 20 processes), unless so many DIA processes are busy on other activities that the number of free DIA would fall below 5.
Hope this helps,
Mark

Hierarchies Job Failing The job process could not communicate with the dat

Hi Experts,
We have a group of hierarchies that run as a separate job on the DS schedules. The problem is this when we schedule the job to run during the production loads it fails but when we run immediately after it fails it runs completely fine. So it basically means that if i run it manually it runs but when its scheduled to run with the production job it fails. Now the interesting thing is If i schedule the job to run anytime after or before the production jobs are done. It works fine.
The error i get is
The job process could not communicate with the data flow <XXXXXX> process. For details, see previously logged
                                                           error <50406>.
Now this XXXXX DF has only Horizontal Flatenning and it does not run as separate process because if i have it has separate process it fails with an EOF . So i removed the run as separate process and changes the DF to use in memory .
Any Suggestion on this problem...

Thanks Mike.. I was hoping its a memory issue but the thing i don't understand is when the job is scheduled to run with the production job it fails. when i manually run the job during the production job it runs, this kinda baffles me.

Sm59 & load distribution

Hi Friends,
I have a question about sm59. Now, I am creating r3 connections from sm59. Lets say the connection name as 'TEST'. In this connection I don't select load distribution. And when I am calling the bapis;
call funciton 'BAPI1'
destination TEST
call function 'BAPI_TRANSACTION_COMMIT'
destinaton 'TEST'
I see that If I don't call BAPI_TRANSACTION_COMMIT BAPI1's change operations is not implemented. And If I call BAPI_TRANSACTION_COMMIT, BAPI1's change operations are done. So, I think that 'different function calls via same destination are using same session !!' Maybe this assumption is wrong, If wrong please correct.
On the other hand, I want to use load distribution in R3 connection. My real question is in this point. As known, in load distriution selection, the balancer distributes the client to different servers. I need to call two function(BAPI1 and its commit). And there is a possibility;
while calling BAPI1, server1 is used
while calling COMMIT BAPI server2 is used.
Like a this possibility, my BAPI1's change operations will be done? I mean that different server will use the same session?
And can you give document information, about load balancing in sm59.
Thanks.

Hi Huseyin,
Its really weared situation...really speaking if you call two BAPI's separately it cannot be a part of same process...
...Anyway, I think correct solution would be to create another z wrapper function module and inside z-wrapper function module you can call both BAPI's...As we know its is manadatory to call Commit Work after calling BAPI's in order to reflect changes.
One more solution you can call Inbound Proxy and you can call both BAPIs there.

How to restore system RAM memory when i run DI batch job process

How to restore system RAM memory when i run DI batch job process
I use SAP-B12005SP53 and i develop with Business Partner Object

HI ALL
TAKE CARE: Nothing was working in VB6, but in .NET it sets the default value !
from help of VS.
When you assign Nothing to an object variable, it no longer refers to any object instance. If the variable had previously referred to an instance, setting it to Nothing does not terminate the instance itself. The instance is terminated, and the memory and system resources associated with it are released, only after the garbage collector (GC) detects that there are no active references remaining.
Garbage Collector distroyes the objects at the end of the sub of function, not in the loop.
So use local variables when you loading the 7000 items. For me working fine and i do not have a memory problems. I am loading 50000 items with prices from EDI file, and memory usage stops at 120MB.
1st solution create a sub or a function to populate the data, and run this for every items by as single rutin,
sub x
    Dim obj As New Object()
        Try
... put here your update code
        Catch ex As Exception
        Finally
            GC.Collect()
        End Try
end sub
This free up the memory when Garbage
2nd solution: use inner loop definition
sub x
Try
            Do While True
                Dim obj As New Object()
            Loop
        Catch ex As Exception
        Finally
            GC.Collect()
        End Try
end sub
This free up the memory inside the loop.
I recommend to use Friend Class keyword for your addon declaration and do not use modules.
Modules and shared classes will be free up the memory when your program terminates execution.

Getting incorrect value in CCMS: Load Distribution

Dear Experts,
I am Using Ecc 6.0 with db2 udb(DB6) on Aix Os.
I have configured load balancing on my sap system.
But when i am going to see average time of load distribution it appears like this
Instance            Resp.time(ms)
PRD_02             1,480
PRD_01                  1-
PRD_00               2,978
You can see that value for PRD_01 is (1-).
how to correct this value...

- Is that instance included in the load balancing (SMLG)?
- Is that instance configured to have dialog processes?

The advantage ? In simple terms, say you have 3 steps that take 10 minutes, in serial :
Step 1 -> Step 2 -> step 3
10 + 10 + 10 = 30 Minutes to complete.
Now lets say you can run these steps in Parallel at the same time
10
10
10
They will all be finished in 10 minutes, you have saved 20 minutes running in Parallel compared to Serial. In a data warehouse, we can commonly load Dimensions in parallel (providing there are no dependancies) , then we might load the fact tables in parallel also (again , assuming no dependancies).
Load Plans allow you to orchestrate Parallel / Serial calls to interfaces and Package scenarios, you can also run steps in Parallel in Packages using asynchronous scenario calls.
Hope this helps.

How does failover and load distribution work in Operations Manager resource pools?

Hello everyone,
I have a couple of questions in regard to failover and load distribution in resource pools.
What is the criteria for an x-plat or network device to initiate a failover?
How is load distributed in a resource pool - Is it round-robin, performance based or something completely different?
In case more than two management servers are in the same pool, and a management server becomes unavailable, how is load distributed among the remaining resource pool members?
Any help is appreciated.
Thx,
Claus

Hi,
Resource Pools are a collection of Health Services working together to manage instances assigned to the pool.
Workflows targeted to the instances are loaded by the Health Service in the Resource Pool that ends up managing that instance.
If one of the Health Services in the Resource pool were to fail, the other Health Services in the pool will pick up the work that the failed member was running.
And I would like to share this article with you. Hope it helps.

Do you have antiVirus installed on the sharepoint servers?
These folders may have to be excluded from antivirus scanning when you use file-level antivirus software in SharePoint. If these folders are not excluded, you may see unexpected behavior. For example, you may receive "access denied" error messages when files
are uploaded.
Please follow this KB and exclude the folders from Scanning.

Job processing

Dear Experts,
My client has received one processing job for the 1st time. How to map the scenario in Sap.
the customer will provide plain bottle for printing in plastic boxes to be returned after printing in the same box.
My idea is as follows.
1>Create the material plain bottle as sales order stock non-valuated as no excise is involved.
2>Create finished material with a new material type
3>Create sales order
3> Create BOM and routing for finished material assigning plain bottle as component.
4> Create Production order with a new order type with respect to the sales order
5> Create condition type in sales where only service tax and education cess are involved.
6> a new gl will also needs to be created i.e Job processing charges
Please confirm whether I am on the right track and what configuration needs to be maintained in FI, MM, CO and SD.
Please explain...
Best Regards,
Divraj

Hi Ajay,
I need suggestion for below mentioned problem.
We will be receiving suppose 10000 bottle for printing as job work. There is 1% breakage allowance....
Now if 100 bottles are broken we need to return to the customer those 100 bottles in broken condition.
How to map this.
What we have opined.......
As we have created plain bottle as non-valuated. We will receive the same through 501 E mvt. type i.e without PO against SO in a different storage location.
Instead of creating a seperate material code for broken bottle we will generate the same plain bottle through 531 movt type on order itself in a separate storage location. Then do 502 movement return to customer.
Please suggest the best method...
Regards,
Divraj

Distribution Manager failed to process package triggers an update of the packages

Hi all,
we have randomly following issue:
SCCM 2012 Sp1 CAS, takes a snapshot of a Windows update package in the morning (not sure how the frequency of this check is done). If for any reason it fails, SCCM automatically redistributes the package to all sites. This happened this morning again for 5
Windows updates packages. You understand that this means GB sent to all Secondary sites (66) with an useles amount of data sent out.
From the Status messages I see
Information Milestone RC0 06.11.2014 07:12:11 SCHVSGGSC600.rccad.net SMS_DISTRIBUTION_MANAGER 2300 Distribution Manager is beginning to process package "SUP-2014.09" (package ID = RC00017B).
Then lot of updates lists with comment taking a snapshot and finally
Error Milestone RC0 06.11.2014 07:12:29 SCHVSGGSC600.rccad.net SMS_DISTRIBUTION_MANAGER 2302 Distribution Manager failed to process package "SUP-2014.09" (package ID = RC00017B). Possible cause: Distribution manager does not have access to either the package source directory or the distribution point. Solution: Verify that distribution manager can access the package source directory/distribution point. Possible cause: The package source directory contains files with long file names and the total length of the path exceeds the maximum length supported by the operating system. Solution: Reduce the number of folders defined for the package, shorten the filename, or consider bundling the files using a compression utility. Possible cause: There is not enough disk space available on the site server computer or the distribution point. Solution: Verify that there is enough free disk space available on the site server computer and on the distribution point. Possible cause: The package source directory contains files that might be in use by an active process. Solution: Close any processes that maybe using files in the source directory. If this failure persists, create an alternate copy of the source directory and update the package source to point to it.
This triggers immediately an update of all DPs
Information Milestone RC0 06.11.2014 07:43:52 SCHVSGGSC600.rccad.net SMS_DISTRIBUTION_MANAGER 2304 Distribution Manager is retrying to distribute package "RC00017B". Wait to see if the package is successfully distributed on the retry.
Any idea
How this can be avoided, since nobody changed the package and we suppose it was a temp connection issue between the CAS and the package repository server
If this check can be set up to once a week for instance or even less?
Thanks,
Marco

Hi Daniel,
thanks for the prompt answer. Actually I saw it yesterday at least for 1 package (the last one). The error is generate by SQL killing a task
Adding these contents to the package RC00010D version 347.

Now as I mentioned it was probably an SQL (more likely) or networ issue, however the question was more about how to avoid that. Finally the packages were not changed and if possible I would avoid any automatic SCCM action on packages unless an operator manually
triggers them.
I didn't see any error today, so it should not be a configuration issue.
Is this possible?

Disabling the cost distribution button on the Process Purchase Order Screen

This is probably a simple question, but we have been unable to find the place to disable cost distribution on the SRM Process Purchase Order screen for limit orders ONLY. Basically, we just want this functionality to not be available to users. Can anyone direct us to the correct configuration for this? Or do we need to edit the BADI?
Thanks in Advance!

Hello,
You can hide this field by creating a screen variant through SHD0 transaction. I have tested here and I
could hide it (GV_DIST_IND in Program SAPLBBP_PDH_ACC screen 1000).
In the screen variant you should mark the output of GV_DIST_IND field.
However, this option would hide this button for all documents.
Kind regards,
Ricardo
