Difference between Clustering and Load balancing

          What is the difference between Clustering and Load balancing?
          For example, We use Cisco Arrowpoint to do load balancing and it works fine for 3
          Sun solaris boxes/WebLogic 6.1 SP1.
          So what is the value addition to buy clustering license?
          Thanks

Hi.
          Among other things, clustering allows you to share app data (such as http session
          data) across cluster members, allowing you to failover should one cluster member
          crash.
          If your app is stateless then this doesn't mean much - load balancing alone would
          probably be ok for you.

What are differences between clustering and partitioning?

Thank you for reading my post
Can some one let me know what is different between clustering and partitioning?
What i think is as follow:
In clustering we have one storage (one hard disk for example) and several instances which use that storage to server the applications
in partitioning, we have multiple instances and each of them has its own storage (hard disk) but all of these instances and hard disks serve one application.

The word "cluster" has different meanings in Oracle.
Another kind of cluster is a database object where
master and detail rows are stored together in the
same block. Table joins are very efficient, but
reading data from one table and not another tends to
take longer. These kinds of clusters are vary rarely
used.Do not forget single table sorted hash cluster!

Difference between Initialization and Load-of-Program

Hi All!
Could anybody tell me what exactly is the difference between Load-of-program and initialization using a sample program?
Thanks in advance...
Jag.

Hi Jag
It seems not so much difference. But INITIALIZATION block is peculiar to executables.
<b>INITIALIZATION</b>: Only occurs in executable programs. The ABAP runtime environment triggers the INITIALIZATION event before the selection screen is processed, at which point the corresponding event block is processed.
<b>LOAD-OF-PROGRAM</b>: When an ABAP program is loaded in an internal session, the runtime environment triggers the LOAD-OF-PROGRAM event, and the corresponding event block is executed.

Toplink cache and clustering and load balancer

Hi All:
I have an application deployed on AIX platform. This is developed using struts, toplink and session ejbs.
Oracle 10g is installed on two AIX machines and these are in cluster. My j2ee application is deployed on oracle 10g app server.
I will be having loadbalancer in the front of this cluster. Even now with out loadbalancer , with oracle app server clustering I am observing the request sharing between two servers.
My problem is that as I am using the toplink and it uses the cache, what will be the impact on my application on below scenerios.
1. user A connects to machine 1 and reads object using toplink. At the same time user B connects to machine 2 and also reads the same object. User A will update the same object and commit it. User B will use this object and will put this as a child of some parent object and commit the parent.
I mean to say that due to different two machines, cache will not be in sync and this may cause a major problem.
Please provide your input to this.
Thanks,
Viral

Viral,
This is what ORM and more specifically TopLink help you solve.
What you need to do is configure TopLink to use your appropriate locking mechanisms. I recommend optimistic but in some cases pessimistic locking is appropriate too.
Optimistic locking will detect if the second machine attempts to modify an object that has already changed on the database. There is also support to force the UnitOfWork to verify that the optimistic locking field(s) have not changed when using the concurrent object in another relationship.
UnitOfWork.forceUpdateToVersionField(Object, boolean)
http://download-west.oracle.com/docs/cd/B14099_04/web.1012/b10491/oracle/toplink/sessions/UnitOfWork.html#forceUpdateToVersionField(java.lang.Object,%20boolean)
This method will allow you to detect if the instance you are about to use has been modified by another transaction with or without updating its version field.
Cache sync (coordination) is intended to minimize stale cache conditions but locking is the only way to guarantee it is handled at the database level.

Difference in the Balance between FS10N and Customer Balances in Local Curr

Hi,
When i am trying to match the Balances between FS10N and Customer Balances in Local Currency for the Period 8, we are getting the difference, The reconcilliaton Account was changed on 30.08.2010.
Please help Us in tracing the differences between FS10N and Customer Balances in Local Currency.
What could be the possible reasons for the differences..
Thanks

Hi Varshani,
Please use the program/report SAPF070 to compare or reconcile your AR with GL balances. You can use SAPF071 to correct any inconsistencies. Provided below documentation for these programs.
SAPF070 - Compare Documents and Account Transaction Figures
Description
This program compares debit and credit transaction figures in customer, vendor, and G/L accounts with the debit and credit totals from documents posted in the corresponding posting period (accounting reconciliation). The sales totals are also compared for customer and vendor accounts. There is no separate comparison for special G/L transactions.
A comparison for G/L accounts can be made in company code currency and in parallel currencies (such as group currency). A comparison for customer and vendor accounts can only be made in company code currency.
After the program has finished, a message is issued to the user that started the program. This message summarizes the results of the reconciliation.
Output
The program compares the totals of an account on a periodic basis. If the debit and credit total differs between account and documents, the account is printed with the debit and credit totals and the difference.
Differences in G/L accounts are shown per transaction currency. The first line shows the amount in local currency, the second line shows the amounts in transaction currency.
If a document which falls within the selection range is posted during the program run, the program is terminated since a reliable result can no longer be delivered.
SAPF071 - Adjust Balances after Comparing Documents/Transaction Figures
Description
If a financial accounting comparative analysis (SAPF190) or a comparison of documents and transaction figures (SAPF070) shows that there are differences between documents and transaction figures, you can use this program to make an adjustment. The documents form the basis for this adjustment. The program adjusts the (redundant) transaction figures, which are only totals of amounts from documents.
Requirements
All of the following listed requirements must be fulfilled:
1. A financial accounting comparative analysis (SAPF190) or a comparison of documents and transaction figures (SAPF070) must be made, and differences must be found between documents and transaction figures.
2. There must not be any inconsistent documents found. These are listed in both SAPF070 and SAPF190 as well as in this program.
3. There cannot be any problems in the other modules. Caution: You have to check this yourself. Financial Accounting may be correct but the other modules may not be, and this will adversely affect the program run.
4. You can only make the adjustment in the ledgers which are compared by program SAPF070. This is ledger 00 or a user-defined ledger for all parallel local currencies except the group currency. (The program displays these ledgers). You have to adjust any additional ledgers as well as average balance ledgers yourself.
5. No documents during the period in which you are adjusting transaction figures can be archived. Caution: You must ensure that these documents are not archived by establishing appropriate organizational rules and procedures.
Only use this program after consulting with SAP or after checking the prerequisites thoroughly.
You should adjust all differences together for a single company code. By setting the program parameters you can limit the adjustment to G/L currency types or to balances in subledgers.
It is advisable to execute a test run first, which will list any differences that are found.

Difference between Reconstruction and regular load from PSA

Gurus,
      What is the Difference between Reconstruction and load from PSA into datatarget.I understand that during Reconstruction we are not loaing data from R3.
      I have a cube and there are 3 requests in that.I deleted all the requests went to PSA and selected one of the requests and selected reconstruct from this.I went to cube and I can see this selected request in PSA in the reconstruction requests of cube.I submitted the reconstruction/Insert button there.
      Is this the procedure to do reconstruction.If yes then how is it different from regular load from PSA.
Thanks

If look function wise both are doing samething. But there is difference in data flow, PSA is used as staging area. If we choose at first place to load only to PSA and analyze our load do manual editing if needed and then load to data target in this case ofcourse reconstruct option is not available or we could parrallely or sequencialy load to data target beside laoding into PSA. So now having already have loaded into data target if some how we needed to delete and reload we can reconstruct the request or run normal load from PSA.

Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.
Just have a look at these links:

Could any one tell me what is the difference between swfloader and module loader?

Hi All,
                      Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

Hi,
ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client. In other words, the class factory is a singleton for a given url. Unloading is a totally different story. As you note, not everything is truly unloadable, because there may be lots of references to stuff in
the module that will keep it alive and un-GC'ed.
I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system. I will assume that you are, because otherwise it would be obvious where to expose methods. You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.
                Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
Also try and refer to this link which was previously discussed in this forum..

Difference between G/L Account Balance and PCA Balance

Friends,
After executing KE5T for the period 6 we are seeing a difference in the G/L a/c balance figures and the profit center figures for 2 balance sheet accounts. In one case the PCA balance figures are greater than the G/L a/c balance figures and vice versa in the 2nd case.
What is the procedure to be followed in such cases? Is there any standard program that can identify the postings that are causing the differences?
Please confirm at your earliest.
Thanks & Regards,
Sameer S. Gupte

Eli,
Thanks for the reply.
However, the note 126910 specifically mentions that it is not to be used for balance sheet account balances transferred to PCA using 1KEK.
Can you please advise about reconciling differences between PCA and balance sheet accounts.
Thanks & Regards,
Sameer S. Gupte

Balance difference between GL and Asset

Hi Exps,
I found the balance differences between asset and gl throu transaction ABFST2.
how to know from where the differences will come in assets and GL? if found how to adjust the differences?
Soma

any suggetions please...
If i retire the asset in current period, what is the parameters to take to retire the asset? asset cap.date: 01.11.2004, life time: 5 Yrs. Dep.rate:20%.
system is not allowing to transfer with value date on 01.02.2004. for this case which value date i should take? if i transfer this to new asset with current date, what is the life time and depreciation. depreciation is taken as over rem.life pro rata to zero.

Data Centre Interconnection - firewall and load balancer deployment

Hi all,
I've read lots of Cisco docs/white papers on DCI - Layer 2 extension between DCs, but as yet I cannot find any decent information on how best to deploy firewalls and load balancers in such a design. I've seen refs to FHRP isolation on Nexus 7k (and possible 6k if you use DCI block) but nothing on the services elements.
The services element seems to be a complete minefield here:
- active/standby across sites, or deploy resilient pairs in each site?
- how to align optimal traffic flows inbound and ooutbound (RHI, SNAT, etc.)
- best practice suggestions ideally.
Cisco DCI docs seem to always gloss over the fact that most customers would have to deal with firewalls and load balancers here, and simply refer to 'coming soon' for that info.
If anyone has any good suggestions/links to docs explaining detailed implementation info would be much appreciate
Thanks
Phil

MAIN DIFFERENCES BETWEEN PARALLEL AND SEQUENTAIL PRCESSING???

HI PALS,
I WANT THE COMPLETE DIFFERENCES BETWEEN PARALLEL AND SEQUENTIAL PROCESSING!
IN THE CONTEXT OF RFC.

Hi
Parallel Processing
To achieve a balanced distribution of the system load, you can use destination additions to execute function modules in parallel tasks in any application server or in a predefined application server group of an SAP system.
Parallel-processing is implemented with a special variant of asynchonous RFC. Itu2019s important that you use only the correct variant for your own parallel processing applications: the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword. Using other variants of asynchronous RFC circumvents the built-in safeguards in the correct keyword, and can bring your system to its knees
Details are discussed in the following subsections:
·        Prerequisites for Parallel Processing
·        Function Modules and ABAP Keywords for Parallel Processing
·        Managing Resources in Parallel Processing
Prerequisites for Parallel Processing
Before you implement parallel processing, make sure that your application and your SAP system meet these requirements:
·        Logically-independent units of work:
The data processing task that is to be carried out in parallel must be logically independent of other instances of the task. That is, the task can be carried out without reference to other records from the same data set that are also being processed in parallel, and the task is not dependent upon the results of others of the parallel operations. For example, parallel processing is not suitable for data that must be sequentially processed or in which the processing of one data item is dependent upon the processing of another item of the data.
By definition, there is no guarantee that data will be processed in a particular order in parallel processing or that a particular result will be available at a given point in processing.
·        ABAP requirements:
¡        The function module that you call must be marked as externally callable. This attribute is specified in the Remote function call supported field in the function module definition (transaction SE37).
¡        The called function module may not include a function call to the destination u201CBACK.u201D
¡        The calling program should not change to a new internal session after making an asynchronous RFC call. That is, you should not use SUBMIT or CALL TRANSACTION in such a report after using CALL FUNCTION STARTING NEW TASK.
¡        You cannot use the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword to start external programs.
·        System resources:
In order to process tasks from parallel jobs, a server in your SAP system must have at least 3 dialog work processes. It must also meet the workload criteria of the parallel processing system: Dispatcher queue less than 10% full, at least one dialog work process free for processing tasks from the parallel job.
Function Modules and ABAP Keywords for Parallel Processing
You can implement parallel processing in your applications by using the following function modules and ABAP keywords:
·        SPBT_INITIALIZE: Optional function module.
Use to determine the availability of resources for parallel processing.
You can do the following:
¡        check that the parallel processing group that you have specified is correct.
¡        find out how many work processes are available so that you can more efficiently size the packets of data that are to be processed in your data.
·        CALL FUNCTION Remotefunction STARTING NEW TASK Taskname DESTINATION IN GROUP:
With this ABAP statement, you are telling the SAP system to process function module calls in parallel. Typically, youu2019ll place this keyword in a loop in which you divide up the data that is to be processed into work packets. You can pass the data that is to be processed in the form of an internal table (EXPORT, TABLE arguments). The keyword implements parallel processing by dispatching asynchronous RFC calls to the servers that are available in the RFC server group specified for the processing.
Note that your RFC calls with CALL FUNCTION are processed in work processes of type DIALOG. The DIALOG limit on processing of one dialog step (by default 300 seconds, system profile parameter rdisp/max_wprun_time) applies to these RFC calls. Keep this limit in mind when you divide up data for parallel processing calls.
·        SPBT_GET_PP_DESTINATION: Optional function module.
Call immediately after the CALL FUNCTION keyword to get the name of the server on which the parallel processing task will be run.
·        SPBT_DO_NOT_USE_SERVER: Optional function module.
Excludes a particular server from further use for processing parallel processing tasks. Use in conjunction with SPBT_GET_PP_DESTINATION if you determine that a particular server is not available for parallel processing (for example, COMMUNICATION FAILURE exception if a server becomes unavailable).
·        WAIT: ABAP keyword
WAIT UNTIL
Required if you wish to wait for all of the asynchronous parallel tasks created with CALL FUNCTION to return. This is normally a requirement for orderly background processing. May be used only if the CALL FUNCTION includes the PERFORMING ON RETURN addition.
·        RECEIVE: ABAP keyword
RECEIVE RESULTS FROM FUNCTION Remotefunction
Required if you wish to receive the results of the processing of an asynchronous RFC. RECEIVE retrieves IMPORT and TABLE parameters as well as messages and return codes.
Managing Resources in Parallel Processing
You use the following destination additions to perform parallel execution of function modules (asynchronous calls) in the SAP system:
In a predefined group of application servers:
CALL FUNCTION Remotefunction STARTING NEW TASK Taskname
DESTINATION IN GROUP Groupname
In all currently available and active application servers:
CALL FUNCTION Remotefunction STARTING NEW TASK Taskname
DESTINATION IN GROUP DEFAULT
Sequential Processing
In the following cases, the system chooses sequential (non-parallel) processing:
●      In table RSADMIN, entry QUERY_MAX_WP_DIAG has value (column value) 1.
●      The entire query consists of one sub-access only.
●      The query is running in a batch process.
●      The query was started from the query monitor (transaction RSRT) using various debug options (for example, SQL query display, execution plan display). See, Dividing a MultiProvider Query into Sub-Queries.
●      The query requests non-cumulative key figures.
●      Insufficient dialog processes are available when the query is executed. These are required for parallel processing.
●      The query is configured for non-parallel processing.
●      You want to save the result of the query in a file or a table.
In Release SAP NetWeaver 7.0, the system can efficiently manage the large intermediate results produced by parallel processing. In previous releases, the system terminated when it reached a particular intermediate result size and proceeded to read data sequentially. This is no longer the case. Therefore, the RSADMIN parameter that was used in previous releases for reading a MultiProvider sequentially is no longer used.

Difference between scalable and failover cluster

Difference between scalable and fail over cluster

A scalable cluster is usually associated with HPC clusters but some might argue that Oracle RAC is this type of cluster. Where the workload can be divided up and sent to many compute nodes. Usually used for a vectored workload.
A failover cluster is where a standby system or systems are available to take the workload when needed. Usually used for scalar workloads.

ABST2 - Differences between Assets and G/L accts

Hi Experts
We are working on ECC 6.0 and INR is our local currency.
At the end of FY 2007 by mistake direct postings were made to Dep Fund Account which is a Recon a/c and FY 2007 was closed
And because of which FI-GL and FI-AA doesnt match by INR 37353.71 (amt posted in above doc) as shown in ABST2
I've referred SAP notes 104567 & 69225 and found the note 69225 relevant to follow as the difference has not resulted in the current or open years.
So we have passed direct entry which is exactly the reversal of entry posted above using ABF1 (INR -37353.71)
After posting the 2nd document, in ABST2 another line has appeared of INR -37353.71. Although the sum for my recon GL is now zero.
The output of ABST2 is as below now -
Sc Acct no.   BusA Year SG 1st local difference LCurr Doc.no.    Period
AS 31100                2009               37,353.71-        INR     W004
AS 31100                2009               37,353.71         INR     W004       999
When I come out of ABST2 , addition to 1st, error no 2 is also coming which I thought would disappear.
1.Differences between assets and G/L accts in the balance carried forward
     Message no. MQ555
2.Differences between assets and G/L accounts at the key date
     Message no. MQ557
Is still something else needs to be done?
Or can I move ahead as the summation of the difference is now zero?
Please suggest.

We referred to SAP and they suggeted that the tagging of W004 in both the lines means that now there is no error even system prompts it as error.
So we continued with the transactions and after closing the FY 2009, today when we run ABST2, we dont get any error messages as there is no difference left between Assets & GL.
