How is utilization index calculated?

Hi there,
When I create a dashboard widget, I can select from top highest or top lowest utilization. I am curious how the utilization is calculated? Is it average over all metrics or is there some sampling?
Thanks,
-Nigel

In other words, if I take a 10 mpx file, a 16 mpx file, a 24 mpx file and a 40 mpx file; at 100% zoom they will all display 1,680 x 1,050 pixels of that file?
Exactly! Lightroom calls it 1:1 instead of 100% but that is a detail.
So when you are looking at a 10 MP file at 1:1 you see the equivalent of a crop from a 30x20" print, with 16 MP a crop from a 38*25" print, with 24MP, a crop from a 47x31" print and with a 40MP file, a crop from a 60x40" print.
I do these calculations more often as you might be able to tell ;-)

How to utilize index in selection statement

hi
how to utilize index in selection statement and how is it reduces performance whether another alternative is there to reduce performance .
thanks

Hi Suresh,
For each SQL statement, the database optimizer determines the strategy for accessing data records. Access can be with database indexes (index access), or without database indexes (full table scan).The cost-based database optimizer determines the access strategy on the basis of:
*Conditions in the WHERE clause of the SQL statement
*Database indexes of the table(s) affected
*Selectivity of the table fields contained in the database indexes
*Size of the table(s) affected
*The table and index statistics supply information about the selectivity of table fields, the selectivity of combinations of table fields, and table size. Before a database access is performed, the database optimizer cannot calculate the exact cost of a database access. It uses the information described above to estimate the cost of the database access.The optimization calculation is the amount by which the data blocks to be read (logical read accesses) can be reduced. Data blocks show the level of detail in which data is written to the hard disk or read from the hard disk.
Inroduction to Database Indexes
When you create a database table in the ABAP Dictionary, you must specify the combination of fields that enable an entry within the table to be clearly identified. Position these fields at the top of the table field list, and define them as key fields.
After activating the table, an index is created (for Oracle, Informix, DB2) that consists of all key fields. This index is called a primary index. The primary index is unique by definition. As well as the primary index, you can define one or more secondary indexes for a table in the ABAP Dictionary, and create them on the database. Secondary indexes can be unique or non-unique. Index records and table records are organized in data blocks.
If you dispatch an SQL statement from an ABAP program to the database, the program searches for the data records requested either in the database table itself (full table scan) or by using an index (index unique scan or index range scan). If all fields requested are found in the index using an index scan, the table records do not need to be accessed.
A data block shows the level of detail in which data is written to the hard disk or read from the hard disk. Data blocks may contain multiple data records, but a single data record may be spread across several data blocks.
Data blocks can be index blocks or table blocks. The database organizes the index blocks in the form of a multi-level B* tree. There is a single index block at root level, which contains pointers to the index blocks at branch level. The branch blocks contain either some of the index fields and pointers to index blocks at leaf level, or all index fields and a pointer to the table records organized in table blocks. The index blocks at leaf level contain all index fields and pointers to the table records from the table blocks.
The pointer that identifies one or more table records has a specific name. It is called, for example, ROWID for Oracle databases. The ROWID consists of the number of the database file, the number of the table block, and the row number within the table block.
The index records are stored in the index tree and sorted according to index field. This enables accelerated access using the index. The table records in the table blocks are not sorted.
An index should not consist of too many fields. Having a few very selective fields increases the chance of reusability, and reduces the chance of the database optimizer selecting an unsuitable access path.
Index Unique Scan
If, for all fields in a unique index (primary index or unique secondary index), WHERE conditions are specified with '=' in the WHERE clause, the database optimizer selects the access strategy index unique scan.
For the index unique scan access strategy, the database usually needs to read a maximum of four data blocks (three index blocks and one table block) to access the table record.
select * from VVBAK here vbeln = '00123' ......end select.
In the SELECT statement shown above, the table VVBAK is accessed. The fields MANDT and VBELN form the primary key, and are specified with '=' in the WHERE clause. The database optimizer therefore selects the index unique scan access strategy, and only needs to read four data blocks to find the table record requested.
Index Range Scan
select * from VVBAP here vbeln = '00123' ......end select.
In the example above, not all fields in the primary index of the table VVBAP (key fields MANDT, VBELN, POSNR) are specified with '=' in the WHERE clause. The database optimizer checks a range of index records and deduces the table records from these index records. This access strategy is called an index range scan.
To execute the SQL statement, the DBMS first reads a root block (1) and a branch block (2). The branch block contains pointers to two leaf blocks (3 and 4). In order to find the index records that fulfill the criteria in the WHERE clause of the SQL statement, the DBMS searches through these leaf blocks sequentially. The index records found point to the table records within the table blocks (5 and 6).
If index records from different index blocks point to the same table block, this table block must be read more than once. In the example above, an index record from index block 3 and an index record from index block 4 point to table records in table block 5. This table block must therefore be read twice. In total, seven data blocks (four index blocks and three table blocks) are read.
The index search string is determined by the concatenation of the WHERE conditions for the fields contained in the index. To ensure that as few index blocks as possible are checked, the index search string should be specified starting from the left, without placeholders ('_' or %). Because the index is stored and sorted according to the index fields, a connected range of index records can be checked, and fewer index blocks need to be read.
All index blocks and table blocks read during an index range scan are stored in the data buffer at the top of a LRU (least recently used) list. This can lead to many other data blocks being forced out of the data buffer. Consequently, more physical read accesses become necessary when other SQL statements are executed
DB Indexex :Concatenation
In the concatenation access strategy, one index is reused. Therefore, various index search strings also exist. An index unique scan or an index range scan can be performed for the various index search strings. Duplicate entries in the results set are filtered out when the search results are concatenated.
Select * from vvbap where vbeln in ('00123', '00133', '00134').
endselect.
In the SQL statement above, a WHERE condition with an IN operation is specified over field VBELN. The fields MANDT and VBELN are shown on the left of the primary index. Various index search strings are created, and an index range scan is performed over the primary index for each index search string. Finally, the result is concatenated.
Full Table Scan
select * from vvbap where matnr = '00015'.
endselect
If the database optimizer selects the full table scan access strategy, the table is read sequentially. Index blocks do not need to be read.
For a full table scan, the read table blocks are added to the end of an LRU list. Therefore, no data blocks are forced out of the data buffer. As a result, in order to process a full table scan, comparatively little memory space is required within the data buffer.
The full table scan access strategy is very effective if a large part of a table (for example, 5% of all table records) needs to be read. In the example above, a full table scan is more efficient than access using the primary index.
In Brief
Index unique scan: The index selected is unique (primary index or unique secondary index) and fully specified. One or no table record is returned. This type of access is very effective, because a maximum of four data blocks needs to be read.
Index range scan: The index selected is unique or non-unique. For a non-unique index, this means that not all index fields are specified in the WHERE clause. A range of the index is read and checked. An index range scan may not be as effective as a full table scan. The table records returned can range from none to all.
Full table scan: The whole table is read sequentially. Each table block is read once. Since no index is used, no index blocks are read. The table records returned can range from none to all.
Concatenation: An index is used more than once. Various areas of the index are read and checked. To ensure that the application receives each table record only once, the search results are concatenated to eliminate duplicate entries. The table records returned can range from none to all.

Let's say your application module is com.yourcompany.someapp.services.MyService, and let's say you authored a method like the following in the MyServiceImpl.java file:
public void doSomething(int i, String s) {
}and you exposed this AM custom method using the AM editor.
BC4J design time will automatically create you the com.yourcompany.someapp.services.common.MyService interface that will look like this if you go look at the source code:
package com.yourcompany.someapp.services.common;
import oracle.jbo.ApplicationModule;
public interface MyService extends ApplicationModule {
public void doSomething(int i, String s);
}To use your custom method from a client, just cast your ApplicationModule to your custom interface like this:
import com.yourcompany.someapp.services.common.MyService;
MyService mySvc = (MyService)yourAM;
mySvc.doSomething(1,"foo");

and now i want to pass
one field ED1 which i has calculated separatly and i want to pass this value into iznew1
but error is coming that iznew1 is a table with out header line has no component like ED1.
so how can i pass calculated value to internal table iznew1,

When you declare your internal table , make an addtion occurs 0
eg . data : begin of iznew occurs 0 ,
                fields ...
   add the field here ed1.
           end of iznew.
now when you are calculating the value of ed1,
you can pass the corresponding value of ed1 and modify table iznew.
eg
loop at iznew.
iznew-ed1 = ed1.
modify iznew.
endloop.

How do I create calculations in Adobe Pro 9?

When I close "form editing" and test it out, it doesn't work. I have found many videos that show how to create calculations and I follow them exactly as they say and it still doesn't work. What am I missing?

Is you use the first option, "The field is the product of the following fields:" you should see a result. Just make sure the fields you want multiplied or selected.

How is delivery date calculated

How can anyone please explain how delivery date is calculated using forward and backward scheduling
I want to have it broken down into the following steps
for eg for delivery date calculation following dates are used
Material Availabilty Date
Material Staging Date
Pick/pack time
Transportation PLanning date
Loading date
Goods issue date
Transit Date
Delivery Date
Can some one please give me an example and explain wht these dates are
for eg customer needs delivery date on 11/20/2008
how would the system cacluate whether it can meet the delivery date using backward scheduling
and if it doesnt meet how does the system do the forward scheduling
also i am not clear with the following dates
material avaialibilty date
material staging date
transportation date
can some one please explain me all this in detail
Also i have another question at the sales order creation when is shipping point and route determined
coz based on the ATP check only material avaialabilty date is determined and if we have a bacjground job running every 1 hours for atp then immediately when we create a sales order is a route and shipping point determined (just before we save the sales order)
Let me be more clear
Suppose customer representative recevies a order on the phone
he enters sold to party, ship to party ,PO number,delivery date and material number and then hits enter
so at tht time the shipping point and route is determined ?
also when an atp check runs and if the delivery date is not met then the system will propose a new delivery date but if we have a different route configured say for eg overnight so we can meet the delivery date and we want to change this route to overnight what must we do?
should we change the shipping condition in the header?
I am not very sure about the process can you please also explain me this in detail?
Thanks

Hi there,
When a sales order is logged & the user enters the requested delivery date, system 1st does the backward scheduling date. Pla note that the factory calender mentioned in the shipping point & route plays a crutial role in defining the working days & confirmed delivery date.
For eg: Customer has raised an order on 11/15 & requests delivery on 11/20/2008.
the following times are important in delivery scheduling.
Transit time: maintained in route
Loading time maintained in the shipping point
Transportation planing time maintained in the transportation planning point.
pick pack time maintained in the shipping point.
Material availability time maintained in MM02 --> MRP screens. This is the time that the material can be manufactured (for inhouse producted items) or external processing time (for externallly procured materials like TAS items).
From the requested delivery date 11/20 system does the backward scheduling & determines the following dates:
Goods issue date, loading date, pick pack date, transportation planning date & material availability date.
Time between:
goods issue date - reqested delivery date: transit time
Goods issue date - loading date: loading time
transportation planning date - pick pack date: picking pack time
Material availability date - transportation date: transportation planning time.
Consider that the factory calender has all days of the week as working dates (to make it simple to explain). Also transit time is 3 days, loading time is 1 day,pick pack time is 1 day, material availability time is 3 days.
From 11/20 ussing backward scheduling system determines the following dates:
Goods issue date: 11/17
Loading date: 11/16
Pick pack date: 11/15
System will check if material is available on the 11/15 to start pick / pack. If it is available then system will confirm the reqested delivery date. Else it will check when the material is available. For eg basing on the MRP settings mnaterial is available only on 11/18. So from 18th system does forward scheduling & redetermines all the dates. So pick / pack date is 11/18. Loading date is 11/19, goods issue date is 11/20 & possible delivery date is 11/23. So system will confirm the delivery date on 11/23. This is when complete delivery is required. If partial delivery is allowed, then system will check how much quantity is available on 11/15. Accordingly it will give 2 delivery dates.
In the above example include teh factory calender which will have 5 day week with Fri & Sat as holidays. Accordingly dates will change.
Here replenishment lead time also plays an imp role. Pls refer http://help.sap.com/erp2005_ehp_03/helpdata/EN/6b/2785347860ea35e10000009b38f83b/frameset.htm for further information

I have developed the Custom Screen in screen 0101 and called in PBO of program SAPLIQS0 7790 screen.
The Screen in calling perfectly .The Custom screen having different fields like Raw cost, Intermediate cost, Finished cost, SCAR Cost and Sales Order Cost Etc... These fields are out put filed types. No input for these screens.. I have few doubts regarding this
How to populate the calculated values in Custom screen?
Where we wrote the code to populate the calculated values in custom screen?
You have any idea please guide me

As your screen fields should be global variables in SAPLXQQM, you may initialize them by implementing function module EXIT_SAPMIWO0_008 which also belongs to SAPLXQQM (Customer Exit: Transfer Notification Data to User Screen)

How to judge index health

Hi
i just want to know how to judge index is healthy
i know i should look at
BLEVEL , LEAF_BLOCKS , DISTINCT_KEYS , CLUSTERING_FACTOR
in dba_indexes
but how to calculate from this value the health of an index
I know that BLEVEL should be 3 or less , any other rules?
Thanks very much

Thanks for all replies , BLEVEL is 4 or more means u need to rebuild ur index.
After reading , i am including example of more jnior dbas to help them understand , wen i can say that clustering factor is good or bad for an index
Ex:
suppose i have T1 table , and i have Id.T1 indexed with index called IDX1 ,
IF
select blocks from dba_tables where table_name ='T1';
= or close to
select clustering_factor from dba_indexes where index_name = 'IDX1';
then the clustering factor is very good. because that means each visit to 1 index block
will nearly fetch 1 data block from the table (data in the table is not randomly inserted accoring to the indexed column(ID))
but if the select clustering_factor from dba_indexes where index_name = 'IDX1';
is much higher than the blocks of the table and nearly = to the number of index entries (or the count(distinct values to the indxed column) (ID) )
then the clustering factor is very bad and the CBo may prefer to Full table scan rather than access the table by index
