When and how to create a package

I have a doubt about how Oracle loads a package.
Let's suppose I have a package PACK1 with N procedures inside. When I execute a statement such an EXEC PACK1.PROC3(), does Oracle load all the N procedures of the package PACK1 into the SGA? I ask for that for a simple reason. I usually create a package according to the fact that all the procedures inside that package are "connected" among them in some way. A collegue of mine said me that he would like to put in a same package some more procedures even if they aren't all called among them, but because in some way thay deal with the same topic. Since I think Oracle loads all the package in SGA, I believe it would make sense to put inside a package only the procedures called among them.
Can you help me?
Thanks!

Also if other elements in the package are needed the overhead of calling them is very small, because they are in the same memory area. This means that you can and should group related program units together so that they can share data structures when needed and call each other with minimal overhead

How to create a package and add a file?

Hi all,
I am new to Java and very much much confussed with how to create a package and then include some files any help will be very thankfull.
Thanks for your help
kka.

Steps for creating a package in java are as follows:
Choose a base directory for your classes. For example, you might choose c:\java\packages. Type the following command:
set CLASSPATH=%CLASSPATH%;c:\java\packages
Create subdirectories for each chapter or section, if you don't already have them.
For each of the classes in the subdirectories, add the following line to the very top of each file:
package directory-name;
where directory-name is the name of the subdirectory the class file is located in.
In other directories you may have class files that need to access one of the classes in another directory (package). To do this, write one of the following at the top of the class that needs the other class:
import subdir.*;
or
import subdir.classname;
Use the class by name in the new class file.
Note that you can create sub-packages by creating subdirectories of the original subdirectories, and inserting package statements at the top of the java files in those directories.
Hope this helps!

Hi Matthias,
Sorry, if this reply seems like a products plug (which it is), but this is really how we solve this software engineering challenge at JKI...
At JKI, we create VI Packages (which are basically installers for LabVIEW instrument drivers and toolkits) of our reusable code (using the package building capabilities of VIPM Professional). We keep a VI Package Configuration file (that includes a copy of the actual packages) in each of our project folders (and check it into source code control just as we do for all our project files). We also use VIPM Enterprise to distribute new VI Packages over the network.
Also, as others have mentioned, we use the JKI TortoiseSVN Tool to make it easy to use TortoiseSVN directly from LabVIEW.
Please feel free to contact JKI if you have any specific questions about these products.
Thanks,
-Jim

What is Infoset and How to create

HI Experts
Can any one please explain me what is the purpose of INFOSET in BW
and how to create a info Set between A Info Object and Cube
Thanks

Dear bw user,
Check the below link
http://help.sap.com/saphelp_nw04s/helpdata/en/ed/084e3ce0f9fe3fe10000000a114084/content.htm
Purpose is,
1.To join required data from basic InfoProviders
2.This allows building a relational BI data model with unified views for reporting (seeveral InfoProviders,but only one view). Therefore, we recommend keeping data in smaller, basic InfoProviders that can be flexibly joined for reporting purposes.
3. To allow BEx Reporting on a DataStore object without turning the BEx Reporting indicator on
4. To evaluate time dependencies (for example, join time dependent master data InfoObjects)
5. To be able to create self joins and left outer joins
Creatind in simple steps
Infoset is a Virtual Infoprovider.
Click on InfoProvider under modeling in RSA1 > Select InfoArea > right click Create Infoset > give name and description.
Select the ODS / Master Data Object or more than one ODS and maintain the link.
Infoset works on Join operation.
you can include Infocube if it is BI 7.

Aslo see this link contents
Creating InfoSets
Prerequisites
Make sure that the objects for which you want to define the InfoSet are active. Create any required InfoObjects that do not
exist already and activate them.
Instead of creating a new InfoSet, you can transfer one of the InfoSets that are delivered with SAP Business Content.
Procedure
1. You are in the InfoProvider tree of the Modeling function area in the Administrator Workbench.
Choose the Create InfoSet function from the context menu (right mouse-click) of the InfoArea in which you want to create an
InfoSet. You get to the Create InfoSet dialog box.
2. Type in the following information for your new InfoSet:
¡ technical name
¡ long description
¡ short description
3. In the Start with InfoProvider section, you determine which InfoProvider you want to use to start defining the InfoSet.
¡ Select one of the object types that the system offers you:
ODS Object
InfoObject
Choose an object.
If you want to choose an InfoObject, it must be a characteristic with master data. The system provides you with the
corresponding input help.
4. Choose Continue. You get to the Change InfoSet screen. For more information on editing InfoSets see Editing InfoSets.
When you create an InfoSet, the system generates a corresponding entry for this InfoSet in the subtree of the InfoArea. The
following functions are available from the context menu (right mouse-click) of this entry:
Change
Delete
Object overview
Editing InfoSets
Prerequisites
Before you can get to the screen where you edit InfoSets, the following prerequisites have to be met:
You have created a new InfoSet.
You have selected the Change function from the context menu of an InfoSet entry in the InfoProvider tree of the Modeling
function area in the Administrator Workbench.
You have called the InfoSet Builder transaction, and selected the Change function. You can find additional information
under Additional Functions in the InfoSet Builder .
Procedure
1. You are in the Change InfoSet screen.
Choose a layout for the InfoProvider tree:
InfoArea
InfoProviders Used
All ODS Objects
All InfoObjects
For more information on the screen layout, particularly the layout of the InfoProvider tree, see Screen Layout: Changing
InfoSets.
2. Use the function Where-Used List via AWB to determine which BW objects use the InfoSet that you have selected. You get to
the Administrator Workbench: Where-Used List screen. You are able to work out what would happen in the system if you made
changes to the InfoSet. This helps you to decide whether or not it is sensible to make these changes at this particular point
in time.
3. You define the InfoSet by inserting one or more InfoProviders into the join.
There are several ways of inserting an InfoProvider into the join control:
¡ From the InfoProvider tree:
§ In the InfoProvider tree, double-click on the entry that corresponds to the InfoProvider that you want to add to the join
control.
§ Use the drag-and-drop function to move the InfoProvider into position.
¡ Choose the Add InfoProvider function, to add a particular ODS object or a particular InfoObject independently of the
current layout of the InfoProvider tree. You get to the dialog box of the same name. Enter the data that the system asks you
for.
If you know the technical name of the InfoProvider that you want to add, this method is quicker than switching the layout of
the InfoProvider tree.
When this function is complete, the InfoProvider that you selected is displayed in the join control. For more information on
the structure of the join control, see Join Control.
4. Define the join conditions. For more information see Defining Join Conditions.
5. You can get general information such as object version, date created and date changed via Goto ® Global Settings. You can
also set the indicator Most recent Reporting for InfoObjects from here. You can find additional information under Most recent
Reporting for InfoObjects.
6. Via the button Documents, which appears on the pushbutton bar, you can access document editing for this InfoSet.
7. You can use Check to check the correctness of the InfoSet definition. The log display is shown in the screen area under
the join control.
8. Save the InfoSet. The log display is shown in the screen area under the join control.
9. Activate the InfoSet. After activation, the system executes the checks. The result of the activation is displayed in the
log in the screen area under the join control.
Additional Functions in the InfoSet Builder
You can also use transaction RSISET to call up the InfoSet Builder when you want to edit an InfoSet. Select the InfoSet that
you want to edit. Value help is available for this. Additional functions are also available to help you edit and manage your
InfoSet.
Compare
You use this function from the main menu to check if the InfoProviders used in the InfoSet have been changed and the InfoSet
needs to be adjusted as a result. For more information, see Matching InfoSets.
Jump to object maintenance
You use the InfoObjects and ODS Objects functions to jump to the maintenance screen for the InfoProviders included in the
InfoSet definition.
Info functions
There are various info functions on the status of the InfoSets:
The Object Catalog Entry
The log display for the save, activate, and delete runs of the InfoSet.
Display in tree
You use this function to display in a tree structure all the properties of the A version (active) of the selected InfoSet.
Header data
InfoProvider and its fields
On condition
Wherecondition
The display is empty, if no active version is available.
Version comparison
You use this function to compare the following InfoSet versions:
The active (A version) and modified (M version) versions of an InfoSet
The active (A version) and content (D version) versions of an InfoSet
The modified (M version) and content (D version) versions of an InfoSet
The Display InfoSet screen appears. Depending on which option you choose, the system displays either all of the differences
between the two versions of the selected InfoSet or all of the properties of both versions in a tree structure.
Transport connection using AWB
You use this function to transport an InfoSet into another system.
The Administrator Workbench: Transport Connection screen appears.
The system has already collected all the BW objects that are needed to guarantee the consistency of the target system.
InfoSet data display
You use this function to access the data target browser. If you have already loaded data into the InfoProviders included in
the InfoSet, you can display this data.
Delete
You use this function to delete an existing InfoSet.
Copy
You use this function to copy an existing InfoSet and, if necessary, edit it further.
Show/hide technical names
You can use this function to show alias names for fields. These alias names are necessary in InfoSets, for example to be able
to map self joins. Field alias names start with F, followed by a five-digit number.
Defining Join Conditions
Use
A join condition determines the combination of records from the individual objects that are included in the resulting set.
Before an InfoSet can be activated, the join conditions have to be defined in such a way (as equal join condition) that all
the available objects are connected to one another either directly or indirectly.
Usually, however, only rows containing a common InfoObject or rows containing InfoObjects that share the same basic
characteristic are connected to one another.
Connect tables T1 and T2 using a join and set as a join condition that the F1 field from T1 must have the same value as F2
from T2. For a record from table T1, the system determines all records from T2 for which F2(T2) = F1(T1) is true. In
principle, as many records from T2 can be found as required. If one or more records are found, the corresponding number of
records is included in the result set, whereby the fields from T1 contain the values from the record from T1 under
consideration, and the fields from T2 contain the values of the records found from T2.
Procedure
There are various ways of defining join conditions:
Using a mouse-click
Position the cursor over a row in an InfoObject. Press the left mouse-button and, keeping the left mouse-button pressed down,
trace a line between this row and a row in another object. Providing that the join condition between the two rows that you
have indicated is a valid join condition, the system confirms the join condition by displaying a connecting line between the
two rows.
Using the Link Maintenance pushbutton
You get to the Link Maintenance dialog box.
In a tree structure on the left-hand side of the screen, all of the InfoProviders that are already included in the join are
displayed along with their fields or attributes. If you double-click on one of these fields or attributes, the system
displays on the right-hand side of the screen all of the fields or attributes with which you are able to create a join
condition.
In the Selection column, set one or more of the indicators for the fields or attributes for which you want to create a join
condition. The system generates valid join conditions between the fields or attributes that you specify.
You use the Delete Links pushbutton to undo all of the join conditions.
You use the All Characteristics or the Basic Characteristics Only pushbutton to choose between the corresponding display
variants.
We recommend that you use the Basic Characteristics Only option. The All Characteristics setting displays all of the
technical options involved in a join. If you are not able to find a join condition on the basic characteristic level, then
the All Characteristics setting is useful, but this is an exceptional case.
When you have finished making your settings, click on the Continue icon.
We recommend this method, because the system searches for all the possible join conditions for any field or attribute that
the user specifies, ensuring that the join conditions are defined without errors.
Using the Context Menu Left Outer Join Inner Join
Usually inner-join operators connect all the objects in a join to one another. You can also connect each object with any of
the many other objects by using a left outer join operator.
You can find additional information about usage and special features under Left Outer Join.
If you want to use a left-outer join operator to connect an object, select the object and choose the corresponding function
from the context menu.
The system displays all of the valid join conditions that originate from this object. The connecting lines that represent
these join conditions are labeled as Left Outer Join . InfoProviders, on which a left outer join condition is affixed, are
differentiated by color from the InfoProviders that are connected using an inner join operator.
If you used a left outer join operator to connect two objects, you have to make sure that all on conditions are linked except
for these two objects with the formulation of join conditions.
Note that you cannot add an object, which you have already connected by using the left outer join operator, to another
object.
If you want to use an inner-join operator instead of the left-outer join operator, select the object that you want to
connect, and choose the Inner Join option from the context menu. Again the system displays all the valid join conditions that
originate from this object, and labels the connecting lines accordingly.
Result
Once the join conditions have been defined in such a way as to connect all the available objects to one another, either
directly or indirectly, the InfoSet is ready to be activated.
You click on the Check pushbutton in the pushbutton toolbar to find out if these preconditions for the activation have been
met.
For objects that are joined by a left-outer join operator, there is one extra condition that has to be met, namely that all
the other objects have to be connected to one another either directly or indirectly.

What is this effect called, and how to create it?

Hello,
I' m just curious about this gradation effect's name, and how to create it in Photoshop.

Hi,
Chuck is on the right path. You can construct this with the Filter> Pixelate> Color Halftone..., but then you have to go further.
The pattern is made of two sections of the same halftone channel, one rotated 180 degrees and horizontally offset.
Basic outline:
1. create a linear gradient (you can work in color or black/white)
2. Filter> Pixelate> Color Halftone... use a large radius value for bigger circles, and set the channels to 0 or 90
3. after the filter has run, go to the Channels panel and find a transition in one of the channels that you like
4. Cmd/Ctrl click on the thumbnail of the channel to make a selection
5. go back to the Layer panel and turn off the background layer with the full haltone filter effert.
5. create a new layer, and fill it with a color (you want the dots to fill so invert the selection if needed)
6. create another layer and fill it with a second color
7. rotate the layer from step 6 180 degrees, and move it so the same size circles in the middle of you doc overlap. Now offset horizontally so the center point of circles lies halfway between the layer created in step 5.
8. now marquee a selction that goes approximately half of the doc and create masks for both layers.
9. Invert one fo the masks so that what you see is small dots of one color increasing to the center, and the second color decreasing back t the edge
10 create a third layer and fill it with one of the color and drag copy the mask from the dot pattern layer of the opposite color. Drag this layer in stack order to just above the background layer.
11. create a fourth layer filled with the opposite color of the step 11 layer. Drag this layer in stack order just below the layer you created in step 10.
12. Now (there's surely some math that makes this more accurate but I was just eyeballing it), move the top layer with the mask linked down so it is below the other offset centers by ~60-70 %. Unlink the mask and move it back so more of the dot is exposed and starts to show when it will intersect with the other layer.
13. Do the same mask movement with the second color dot layer so more of that layer's circle shows, until each dots tangents match up.
Here's my layer panel for reference.

steve

About lock object and how to create it

Hi ABAP gurus,
Can any one explain about the Lock Objects and How to create Lock object step by step.
Rgds,

Hi Rangamma,
Check this info.
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.

Where and how to create business rules?

Hi All,
1) Where and how to create business rules?
2) How to configure Rule Engines (Ex: JRULE Engine or any other Rule Engines)?
3) Whar products are available for Rule Engines?
Thanks in advance

Hi,
You have some options on business rules.
If you just want to create business rules that are easy for business owners to edit without a lot of training, Oracle BPM has a simple business rules creation and end user edit capability. The benefits to using the rules that come with Oracle BPM are:
<li> they are simple and easy to edit
<li> end users can get up to speed quickly to edit them
<li> when changed, the business process is immediately impacted
<li> they can use the Oracle BPM business parameters that also come with the product
Drawbacks are:
<li> you can only use Project variables as the variable content inside of them
<li> if a company already has a business rules engine, they are different that the company's standard
Business rules engines have been used with Oracle BPM. If you are a consultant, first ask if there is a standard business rules engine that the company already has purchased that they use (e.g. iLog from IBM, Corticon...). If this is the case, you typically integrate to the rules using a web service interface that the business rules engine exposes.
If they do not already have a business rules engine, consider Jrules. The benefits are:
<li> it is a part of the Oracle BPM Suite that they might have purchased
<li> version 11g of the Jrules is coming out soon with a friendly front end
Hope this helps,
Dan

How to do Enhancements in Reporting & What is Role and How to create Roles

Hi All,
Can any one tell How to do Enhancements in Reporting, and also What is Role and How to create Roles in Reporting?
Plz reply back me on [email protected]
Regards,
Kiran

Reporting Enhancement - RSR00001 - BW: Enhancements for global variables in reporting
And using the SAP Exit - EXIT_SAPLRRS0_001
RSR00001- With this enhancement to global variables in reporting you have the option of determining your default values for variables. You can use this enhancement for variables, for which 'Processing by Customer-Exit' has been selected in the variable maintenance. This is valid for all variable types (characteristic value, node, hierarchy, formula and text variables). You use the Exit EXIT_SAPLRRS0_001 for this.
The Enhancement component (RSR00001) must be assigned to a Project Created using the Transaction CMOD. On activating the Project, the Exit would become active and in turn the logic written inside the Exit.
To ensure that the data warehousing soultion reflects your company's structure and business needs it is critical that you establish who is authorized to access the data.With SAP BW, Authorizations can be defined and maintained by object and can also be applied to hierarchies and these authorizations can be inserted into roles that are used to determine what type of content is available to specific users or user groups.

when should you close the connection? when you're done with it.
how should you close the connection? like this: conn.close();
that said, doing this in a JSP page is bad form and not recommended
JSP's typically don't contain ANY business or data logic

I have read that new purchases of macbook pro will get free upgrade to LION OS. When and how do I go about this?

http://www.apple.com/pr/library/2011/06/06lion.html
The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer. Customers who purchase a qualifying Mac between June 6, 2011 and the date when Lion is available in the Mac App Store will have 30 days from Lion’s official release date to make a request.
Currently that's the only information available. I suspect more will be posted as we get closer to launch.

HOW DB POOLING WORK AND HOW TO CREATA A DB POOLING IN JSP

HI! I'm new in programming JSP and in web programming. I would like to learn how does the DB pooling work and how to create a DB Pooling. THANKS....

Thanks for the idea but i need a more detail one...
Hi,
Db connections are one of the most expensive
operations in an application.So at applicatin launch
only multiple connections to the dbase are opened and
used and returned/closed after usage.
You can have a loop running 10 times creating a
connection every time and putting those in a
Collection object (say hashtable) marked with a key.
Then in the application code , take an available
connection from the hashtable and use it . After use
return /close the connection (your pool can be
incremental..creating 5 connections evey 10-15
minutes).
