EXACT DIFFERENCE BETWEEN FULL LOAD AND REPAIRFULL LOAD?

HI Champ,
Can anyone explain me the exact difference between full load and Repairfull load?Give e some senario where we can go for this?Please.....

Hi,
Full repair can be said as a Full with selections. But the main use or advantage of Full repair load is that it wont affect delta loads in the system. If you load a full to a target with deltas running you again will have to initialize them for deltas to continue. But if you do full repair it wont affect deltas.
This is normally done we when we lose some data or there is data mismatch between source system and BW.
Check the OSS Note 739863 'Repairing data in BW' for all the details
Symptom
Some data is incorrect or missing in the PSA table or in the ODS object (Enterprise Data Warehouse layer).
There may be a number of reasons for this problem: Errors in the relevant application, errors in the user exit, errors in the DeltaQueue, handling errors in the customers posting procedure (for example, a change in the extract structure during production operation if the DeltaQueue was not yet empty; postings before the Delta Init was completed, and so on), extractor errors, unplanned system terminations in BW and in R/3, and so on.
Solution
Read this note in full BEFORE you start actions that may repair your data in BW. Contact SAP Support for help with troubleshooting before you start to repair data.
BW offers you the option of a full upload in the form of a repair request (as of BW 3.0B). If you want to use this function, we recommend that you use the ODS object layer.
Note that you should only use this procedure if you have a small number of incorrect or missing records. Otherwise, we always recommend a reinitialization (possibly after a previous selective deletion, followed by a restriction of the Delta-Init selection to exclude areas that were not changed in the meantime).
1. Repair request: Definition
If you flag a request as a repair request with full update as the update mode, it can be updated to all data targets, even if these already contain data from delta initialization runs for this DataSource/source system combination. This means that a repair request can be updated into all ODS objects at any time without a check being performed. The system supports loading by repair request into an ODS object without a check being performed for overlapping data or for the sequence of the requests. This action may therefore result in duplicate data and must thus be prepared very carefully.
The repair request (of the "Full Upload" type) can be loaded into the same ODS object in which the 'normal' delta requests run. You will find this request under the "Repair Request" option in the InfoPackage (Maintenance) menu.
2. Prerequisites for using the "Repair Request" function
2.1. Troubleshooting
Before you start the repair action, you should carry out a thorough analysis of the possible cause of the error to make sure that the error cannot recur when you execute the repair action. For example, if a key figure has already been updated incorrectly in the OLTP system, it will not change after a reload into BW. Use transaction RSA3 (Extractor Checker) in the source system for help with troubleshooting. Another possible source of the problem may be your user exit. To ensure that the user exit is correct, first load a user exit with a Probe-Full request into the PSA table and check whether the data is correct. If it is not correct: Search for the error in the exit user. If you do not find it, we recommend that you deactivate the user exit for testing purposes and request a new Full Upload. It If the data arrives correctly, it is highly probable that the error is indeed in the user exit.
We always recommend that you load the data into the PSA table in the first step and check the result there.
2.2. Analyze the effects on the downstream targets
Before you start the Repair request into the ODS object, make sure that the incorrect data records are selectively deleted from the ODS object. However, before you decide on selective deletion, you should read the Info Help for the "Selective Deletion" function, which you can access by pressing the extra button on the relevant dialog box. The activation queue and the ChangeLog remain unchanged during the selective deletion of the data from the ODS object, which means that the incorrect data is still in the change log afterwards. After the selective deletion, you therefore must not reconstruct the ODS object if it is reconstructed from the ChangeLog. (Reconstruction is usually from the PSA table but, if the data source is the ODS object itself, the ODS object is reconstructed from its ChangeLog). You MUST read the recommendations and warnings about this (press the "Info" button).
You MUST also take into account the fact that the delta for the downstream data targets is created from the changelog. If you perform selective deletion and then reload data into the deleted area, this may result in data inconsistencies in the downstream data targets.
If you only use MOVE and do not use ADD for updates in the ODS object, selective deletion may not be required in some cases (for example, if incorrect records only have to be changed, rather than deleted). In this case, the DataMart delta also remains intact.
2.3. Analysis of the selections
You must be very precise when you perform selective deletion: Some applications do not provide the option of selecting individual documents for the load process. Therefore, you must first ensure that you can load the same range of documents into BW as you would delete from the ODS object. This note provides some application-specific recommendations to help you "repair" the incorrect data records.
If you updated the data from the ODS object into the InfoCube, you can also delete it there using the "Selective deletion" function. However, if it is compressed at document level there and deletion is no longer possible, you must delete the InfoCube content and fill the data in the ODS object again after repair.
You can only perform this action after a thorough analysis of all effects of selective data deletion. We naturally recommend that you test this first in the test system.
The procedure generally applies for all SAP applications/extractors. The application determines the selections. For example, if you cannot use the document number for selection but you can select documents for an entire period, then you are forced to delete and then update documents for the entire period in the data target. Therefore, it is important to look first at the selections in the InfoPackage exactly before you delete data from the data target.
Some applications have additional special features:
Logistics cockpit: As preparation for the repair request, delete the SetUp table (if you have not already done so) and fill it selectively with concrete document numbers (or other possible groups of documents determined by the selection). Execute the Repair request.
Caution: You can currently use the transactions that fill SetUp tables with reconstruction data to select individual documents or entire ranges of documents (at present, it is not possible to select several individual documents if they are not numbered in sequence).
FI: The Repair request for the Full Upload is not required here. The following efficient alternatives are provided: In the FI area, you can select documents that must be reloaded into BW again, make a small change to them (for example, insert a period into the assignment text) and save them -> as a result, the document is placed in the delta queue again and the previously loaded document under the same number in the BW ODS object is overwritten. FI also has an option for sending the documents selectively from the OLTP system to the BW system using correction programs (see note 616331).
3. Repair request execution
How do you proceed if you want to load a repair request into the data target? Go to the maintenance screen of the InfoPackage (Scheduler), set the type of data upload to "Full", and select the "Scheduler" option in the menu -> Full Request Repair -> Flag request as repair request -> Confirm. Update the data into the PSA and then check that it is correct. If the data is correct, continue to update into the data targets."

What's the difference between "Full Name" and "Account Name"

Just re-install a new OS X Lion. On the "Create Your Computer Account" screen, what's the difference between "Full Name" and "Account Name"?

Your computer name by default would be "John David Appleseed's Macbook Pro"
But you can always change that in System Preferences->Sharing
And yes, the first account you set up will be an administrator.

What is the difference between full checkpoint and incremental checkpoint?

What is the difference between full checkpoint and incremental checkpoint?
And what is checkpoint queue?
Can someone clarify these concepts?
Thanks!

Hi,
there are different types of checkpoints:
- Full checkpoint:
=> DBWR writes all dirty buffers from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
This is the setup point for SMON for a crash recovery.
- Partial checkpoint:
=> DBWR writes all dirty buffers of a singel tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can e triggered by an ALTER TABLESPACE OFFLINE, ALTER TABLESPACE READ ONLY, ALTER TABLESPACE BEGIN BACKUP statement.
Incremental checkpoint:
number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
- Partial checkpoint:
=> DBWR writes all dirty buffers of a single tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- frequency is determined by FAST_START_MTTR_TARGET parameter (new feature to Oracle 9i), with wich you can specify a time in seconds which SMON is allowed to take maximal for a Crash Recovery until the database must be open again.
Dapending on the system you have SMON must calculate the maximum number of Redolog-blocks which it can manage to recover in the specified number of seconds. It will then create so called incremental checkpoints which will be tracked in the so called checkpoint queue in memory.
FAST_START_MTTR_TARGET is auto-tuned in Oracle 10g and Oracle tries to manage (incremental) checkpoint in a fashion that a minimum of I/Os are caused and a minimum time for crash recovery is needed.
If you set LOG_CHECKPOINTS_TO_ALERT to TRUE you will find checkpoint information in the alertSID.log file. You will see FULL and INCREMENTAL checkpoints then.
Hope this clarifies your question,

Difference between Full backup and lncremental level 0 backup

Hi,
What is the difference between Full backup and lncremental level 0 backup?
what I understand is:
Actually incremental backup backups all the block containing data and skips the blocks that are unused.
Similarly full backup backups all the blocks containing data.(does it skip unused blocks ?????).
The only difference that I feel is that the level 0 backup is recorded as an incremental backup in the RMAN repository, so it can be used as the parent for a level 1 backup where Full database backup is not recorded in the Rman respository and cannot be used as parent for level 1 backup.
(if you still feel you have some more points to share regarding the difference between backups, I request to share with me)
so my question here is
Can we use Incremental level 0 backup for full database recovery. Else is there any compulsion like we must only use full database backup for full database recovery?
can anyone throw light on this
with regards;
Boo

nowhere in this thread we talked about the image copies as we are only talking about the incremental backup.
The word "always" has a meaning. If you now wish to say, "well, RMAN will mostly use a level 0 or full backup, except when there are image copies around" then the word "always" doesn't fit your newly-revised description. That would make it an inappropriate word to use. And indeed, it's a factually wrong word to use.
If you want to get really picky about it, incidentally, the words 'datafile copy' appear in a post from me at Aug 4, 2007 6:03 PM whereas your post (in which the "always" word was used) only appears Aug 4, 2007 8:32 PM -a full 2 and a half hours (and and two posts) AFTER the concept of image copies had been mentioned.
But regardless of times: you can't just pretend image copies don't exist just because they haven't been mentioned so far in a thread. If you post "this is the way something ALWAYS works", you'd better be completely right about it, because "ALWAYS" is a big word. And there's no grey about this: either "always" is right, or it's wrong. And in this case, it's wrong: there are many times when RMAN will not do what you baldly asserted it would do. Image copies aren't some rare, exotic beast, either... so the occasions when your 'rule' breaks down are many and common.
until now I was simply beliving in what Oracle docs and metalink notes says
Try not to do that. Because you will fall into error after error if you do. Metalink is not the Holy Gospel of Oracle. Testing is, and it's because I've been testing this stuff since 1999 I will, on this occasion, decline your kind invitation to do "a small test". Been there, done that.
All of which leaves us discussing things that are of no relevance to the original poster, and I have no desire to take the thread off into silly areas of dispute. So I will leave it there, and I have nothing further to say on the matter. RMAN does what it does, and what it does is not what you said it would do. End of story.

Difference between full version and academic version

So I just received my first FCE4 software but it has a sticker saying "Academic: Not eligible for upgrades"
I was wondering why the academic version was a little cheaper... I just wanted to know before I actually open this package, what kind of benefits would I be missing (other than not being able to upgrade to FCE5 I guess...) if I just decide to keep this academic version? Do you recommend just keeping this version or get a regular full version?

There are only 2 differences between the retail & academic versions, and they both pertain to the license, not the functionality of the software:
1 - the price of the academic version is lower than the retail version
2 - when you license (purchase) the academic version, you are not eligible to upgrade it in the future by purchasing an upgrade. (So, if you have FCE4 Academic Version, and someday FCE5 comes out, at that time you would have to purchase a full FCE5 Retail or FCE5 Academic in order to upgrade; you would not be eligible to purchase a reduced-price FCE5 Upgrade version.)

What is difference between additive delta and new status for change record

Hi Experts
Can any one explain me about the difference between additive delta and new status for change record with example
if any one has a document please post it iam thank full to u
thanks
Ahmed
Please search the forum before posting a thread
Edited by: Pravender on Feb 12, 2012 1:54 PM

Hi
Additive delta --- We will get the changed quantity.
say suppose you have sales order and quantity like 1111 30 which is loaded to cube(BW).
now same record qty has changed from 30 to 40. As we have additive delta, we will get new record as 1111 10.
new status for change record: This is same as like After image delta type in standard SAP data sources. for every change in record you should have new record.
say if you have any number which will be generated by system for new/changed record, then you can use this.
You can use this option when delta option set to "numeric pointer"

Difference between Generic extraction and Generic Delta

Hi Experts,
Pleasee give of some information below query:
1) Difference between Generic extraction and Generic Delta.
2) How to achieve Generic delta.
3) When we go for Generic delta instead of generic extraction.
Advance ThankU. Points vl be assigned.
Thanks,
Ragu.R

Hi,
Generic delta is the delta load done using Generic DS.
Generic extraction
Usage:
1. When the standard extractors are not supporting the extraction what you need. If SAP does not have a standard extractor for your need to get data from R3, you would have to go for generic extractor.
2. If you create a custom object say by combining certain base tables in R3 say custom tables ZTAB1 and ZTAB2. These two tables are not SAP provided tables and there will not be any standard extractors. So cases like this you will have to go for generic extractors.
How:
You have to use RSO2 transaction and you can also set delta based on, one of the three characteristics such as timestamp, calday or pointer (a sequence no).
once you create it and activate it. The extractor will be available in ROOSOURCE - (table in R3 where all the data sources are available).

What is the difference between qued delta update and serialized delta upda

what is the difference between qued delta update and serialized delta update?

Hi Ks Reddy,
Queued Delta:
In case of Queued delta LUW's are posted to Extractor Queue (LBWQ), by scheduling the V3 job we move the documents from Extractor queue to Delta Queue(i.e. RSA7) and we extract the LUW's from Delta Queue to BW side by running Delta Loads. Generally we prefer Queued Delta as it maintain the Extractor Log which us to handle the LUW's which are missed.
Direct Delta:
In case of Direct Delta LUW's are directly posted to Delta Queue(i.e. RSA7) and we extract the LUW's from Delta Queue to BW side by running Delta Loads. If we use Direct Delta it degrades the OLTP system performance because when LUW's are directly posted to Delta Queue (RSA7) the application is kept waiting untill all the enhancement code is executed.
Non-serialized V3 Update:With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed. However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.

Difference between full DTP & delta DTP

hi experts,
will u pls explain wat is the exact difference between full DTP & delta dtp.
thanks,
sridhar

Hi Sridhar,
Adding to same.
If in PSA you have 2 request
e.g
Req 2 100 Rec
Req 1 200 Rec
Now First time you are running
If
FULL : All the 2 request will come to DSO
Req 2 100 Rec
Req 1 200 Rec
If
DELTA : All the 2 request will come to DSO
Req 2 100 Rec
Req 1 200 Rec
Now there is one more request comes in your PSA
e.g
Req 3 100 Rec
Req 2 100 Rec
Req 1 200 Rec
Now In case of
FULL LOAD : 3 Request will come in DSO
Req 3 100 Rec
Req 2 100 Rec
Req 1 200 Rec
In case of
DELTA LOAD : 1 Request will come in DSO
Req 3 100 Rec
Hope this will make your doubt clear.
Thanks

Difference between instant client and full oracle client

Everyone,
I had read the below lines from a goldengate pdf. Someone please explain me what is the difference between instant client and full oracle client?
What is the use of XDK libraries.?
" The full Oracle client must be used with GoldenGate so that the GoldenGate programs
have access to the Oracle XDK libraries. Do not use Oracle Instant Client, which lacks
those libraries. You can download the full client from Oracle’s website."
Regards,
SAKTHi

The dealio is this:
When you install client software, you have several options as to the degree of what you get/install. The big chicken dinner is administrator, so you get all kinds of extra features, add-ons, libraries, utilities, etc. At the hard candy Christmas end is instant client, and that has just enough functionality to, as you may surmise by now, connect a client and that's about it. Various libraries have functionality built in to do whatever extra is required. An example is FAN, or fast application notification, used in Data Guard failover. A FAN API (Java) will detect a failover and re-direct a client connection to the new primary. What GG uses XDK for (specifically) isn't of importance to a user, just the fact that it is available for connecting to Oracle is.

Difference between full and target quantity in iteme category

What is the difference between Target quantity and Full quantity in Completion rule in Item Catergory customization?

hi
full quantity is used for quotations
target quantity for contracts
Completion rules
An item may be considered fully referenced if one of the following criteria have been met
An item is complete as soon as it is used as a reference. In this case, the item is fully referenced, even if only a part of the quantity is copied.
An item is only complete once the full quantity has been copied into a subsequent document. If the item is partially referenced, it is possible to enter several sales documents for the item until the quantity is fully accounted for.
An item is only complete once the target quantity (in a contract, for example) has been copied into a subsequent document. If the item is partially referenced, it is possible to enter several sales documents for the item until the quantity is fully accounted for.
The standard version of the system defines an inquiry item as complete even if only one part of the inquiry quantity has been copied into a quotation. On the other hand, when you copy a quotation into a sales order, the quotation is not complete until the quotation quantity has been fully referenced.
Contracts, like quotations, are only considered complete once the full target quantity of the contract has been released.

Diffrance between full repair and Full load .

hello ,
could you please let me know , what is the diffrance between full repair and Full load .
Regards

Hi,
Full Repair :
If you indicate a request in full update mode as a repair request, then it is able to update that request in data targets even if they already contain data from initial runs or deltas for this DataSource / source system combination and with overlapping selections.
Consequently, a repair request can be updated to ODS without checking the sequence of delta requests. The system supports loading in an ODS object by using the repair request without having to check the data for overlapping or request sequencing.
Full load :
Pulls the entire data from the source system to the BI system
Assign points if it helps
