How can I cache an object for unlimited time or for ever.

Hi,
How can I cache an object for ever or unlimited time. What values should be used to in cache-config.xml i.e.
<expiry-delay system-property="tangosol.coherence.zerostage.expiry.delay">XXXms</expiry-delay>
<flush-delay system-property="tangosol.coherence.zerostage.flush.delay">XXXms</flush-delay>
thanks a lot in advance.

Hi Suhas,
If you look in the documentation http://download.oracle.com/docs/cd/E14526_01/coh.350/e14509/toc.htm and more specifically here http://download.oracle.com/docs/cd/E14526_01/coh.350/e14509/appcacheelements.htm#BABDHGHJ you will see the explination for the two configuration items you mention.
The default expiry-delay is zero which means no expiry - that is the data will stay in the cache forever (or until you do a remove). If expiry is zero then flush-delay has a default of zero is used and automatic flushes are disabled.

How can I create a object for a note?

Hi experts,
I need to apply the note 501905 but when I try in the SNOTE transacction I receive this error:
Object REPS Z_MRM_DELETE_PP does not exist; create it
Diagnosis
The SAP Note that you want to implement contains changes to an object that does not yet exist in your system.
SAP Notes contain only changes to objects that already exist. This means that the the system cannot automatically create new objects during the implementation of this SAP Note.
Procedure
1. Cancel the SAP Note implementationl.
2. Create an empty object REPS Z_MRM_DELETE_PP with the corresponding object editor.
3. Restart the SAP Note implementation.
How can I create that Object??
Thanks for the help!

Hi Carlos,
It says that you have to create a new program with a name Z_MRM_DELETE_PP.
Once you create and activate the program you can execute the SAP Note.
All this processure will be written in the SAP Note.
Please Go through the Note using below:
Step1: Use T.code SNOTE.
Step2: Use menu GOTO --> NOTE BROWSER. Provide the Note no and EXECUTE.
Step3: Double click on the displayed line.
Here you will get the information to do before implementing the note.
Go through all the documentation, and once you did all the development given in the note then you can implement the note.

How can i watch native code for hashCode() in Object class?

How can i watch native code for hashCode() in Object class?

Those are two different requirements. You still haven't told us why you want the first one.
The second one is called JNI - Java Native Interface. There is a forum here, and a large amount of documentation, and a book about it.

How can I write new objects to the existing file with already written objec

Hi,
I've got a problem in my app.
Namely, my app stores data as objects written to the files. Everything is OK, when I write some data (objects of a class defined by me) to the file (by using writeObject method from ObjectOutputStream) and then I'm reading it sequencially by the corresponding readObject method (from ObjectInputStream).
Problems start when I add new objects to the already existing file (to the end of this file). Then, when I'm trying to read newly written data, I get an exception:
java.io.StreamCorruptedException
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
Is there any method to avoid corrupting the stream? Maybe it is a silly problem, but I really can't cope with it! How can I write new objects to the existing file with already written objects?
If anyone of you know something about this issue, please help!
Jai

Here is a piece of sample codes. You can save the bytes read from the object by invoking save(byte[] b), and load the last inserted object by invoking load.

How can I use jbo:InputSelect for a char type filed?

How can I use <jbo:InputSelect for a char type filed?
I have two tables. One is room (primary key is room(type is char)), another table is responsibility (foreign ker is room(type is char)). Both tables have same length for room column.
There is a problem:
If I use (in the "DataEditComponent.jsp" file)
<jbo:InputSelect multiple="false" datasource="dsEdit" displaydatasource="roomData" displaydataitem="ROOM" displayvaluedataitem="ROOM" ></jbo:InputSelect>
to get the room input for responsibility from combobox(Datasource roomData is from room table). In the form the room field cannot bind the data in combobox, alway select the first item. And if I select one item and click the update button.There is an error message:
Error Message: JBO-27010: Attribute set with value H409 for Room in Responsibility has invalid precision/scale
I found If I changed the field type from char to varchar2 in database also change the entity objects, it works well. I wonder if there are any diffrence using <jbo:InputSelect tag in char and varchar2 type. How can I use <jbo:InputSelect for a char type filed as i don't want to change my datatype in database at this stage.
I try this in JDeveloper 9.03, 9.034, 9.04. The result is the same.

If I were in your shoes, here's how I would do it:
<%-- Assuming you have dsRoom and dsResponsibility --%>
<%-- Select is an HTML tag --%>
<select name="ROOM" size="1">
<% char roomID =""; // Init your character var
// Open a rowsetIterator to get the records and add them to the LOV
<jbo:RowsetIterate datasource="dsResponsibility" changecurrentrow="true" >
<% roomID = (char)dsResponsibility.getRowSet().getCurrentRow().getAttribute("ROOM"); // Grab the char value
// add the value to the LOV
%>
<option value="<%=roomID%>"><%=roomID%></option>
</jbo:RowsetIterate>
</select>
If you are using this as part of an edit page you may want to utilize the "selected" option of the <option> tag. In one instance I am doing this on an edit page because the use may open an existing record. If I don't account for it, then it will change the DB to contain the first value from the list! You can do a simple check like:
//Set the current record's char
char curRecord = (char)rowEdit.getAttribute("ROOM");
// inside the iterate:
if (curRecord == roomID) {
<option value="<%=roomID%>" selected><%=roomID%></option>
} else {
<option value="<%=roomID%>" ><%=roomID%></option>
Hope that helps!

How to activate all inactive objects for current user

Hi
How to activate all inactive objects for current user ...
... I have found a (long winded) way to do this:
- Environment / Inactive Objects
- Add to Worklist
- Display Worklist
- Select All
- Activate
this will open a dialog titled "Inactive Objects for <username>"
which has the exact functionality I need ... but I can't figure out how to get to this dialog directly - without so many intermediate steps
the SAP docs repeatedly mention the ability to activate the inactive worklist - but do not mention how
does anybody know the TCode for this dialog?
thanks
ps does the term "mass activation" apply to importing change requests rather than development activation?
Edited by: FireBean500 on Jun 4, 2010 11:07 PM

No other way. But usually it's far more simple as all objects are already in our own worklist.
I wonder why your objects are not already in your worklist, as everytime you create or maintain an object, it is added to your worklist.

How can you move the objects from one server to another?

how can you move the objects from one server to another?

Hi,
Collecting objects for Transporting
1. rsa1->transport connection
2. left panel choose 'object type', middle panel choose 'infocube' and 'select objects'
3. then choose your infocube and 'transfer'
4. will go to right panel, choose collection mode 'manual' and grouping only 'necessary objects'
5. after objects collection finished, create request
6. If they are $TMP, then change the package.
7. When you click the Save on the change package, it will prompt for transport. Here you can provide an existing open transport request number, or if you like here itself you can create a new one.
8. You can check the request in SE09 to confirm.
Releasing Transport Request
Lets say you are transporting from BWD to BWQ
Step 1: In BWD go to TCode SE10
Step 2: Find the request and release it (Truck Icon or option can be found by right click on request #)
Note: First release the child request and then the parent request
Steps below are to import transport (generally done by basis )
Step 1: In BWQ go to Tcode STMS
Step 2: Click on Import queue button
Step 3: Double Click on the line which says BWQ (or the system into which transport has to be imported)
Step 4: Click on refresh button
Step 5: High light the trasnport request and import it (using the truck icon)

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).

I don't understand your question.
If you don't know how to use TreeMap why do you think a TreeMap is the correct solution for what you want to do?
If you are just asking how to use TreeMap then there are PLENTY of tutorials on the internet and the Java API provides the methods that area available.
TreeMap (Java Platform SE 7 )
Are you sure you want a map and not a tree instead?

How can we benefit from WebDynpro for ABAP over Normal ABAP

Dear Guru's,
Please guide me what are +Ves of WebDynpro over Normal ABAP. Once all Applications are developed how can we organize them. For Example In SD module there is sequence of Tcodes to be executed this is true for all modules . Is there any concept involved in this new technology.
For What purpose we can suggest someone to implement in an Organization.
Many Thanks in Advance.
Regards
Ram

Hi Ram,
Here Are some comparisions I made w.r.t Webdynpro for ABAP (also some benifits over Java):
1     "Pros:it will be easier to move your development project through the system landscape if both the UI and business logic are in the same development environment.(Update: This is is less of a concern now that CTS+ lets you bundle your WD Java UI developement with ABAP development objects into a single transport, with SPS13. )
2     tons of custom ABAP business logic is easier to access via WD for ABAP
3     WD for ABAP has a code wizard, so easy to build
4     SAP List Viewer and ALV handled better
5      The biggest thing is the NWDI. Most of the SAP customer have ABAP stack, but not everyone has the Java stack. To develop WD Java you need to set up the NWDI envrionment, like SLD, CMS, CBS, DTR, etc. which is a huge effort if you don't have them in place. While for WD ABAP, the environemnt is normally there as given for most of customers if they have the right version.
6     If your business is in SAP system, I would prefer WD ABAP. There are many WD components available in WD ABAP like select-option, Alv table, F4-help which are not available in WD Java. Beside in WD ABAP you can deal the context node in form of internal table which is much more performant than dealing with the contextelement which is the case for WD Java.

How can I pass an object to a function by value?

Hi
I have a function with an argument. this argument is an object. I don't want to alter this object. But java passes this object by reference and some fields in this object are altered after function return.
How can I pass this object by value and keep my original data unbroken?
thanks for any help

How can I pass this object by value and keep my original data unbroken?How you approach it is likely to depend on how much control you have over the code in question. If it's legacy code and has been badly designed, there's probably very little you can do to protect existing code short of a complete refactoring.
What you could do as an interim measure is:
1. Create an immutable wrapper to your existing mutable class.
2. Create new methods that replicate the existing ones, but take the immutable class instead.
3. Deprecate the old methods.
This won't break client code, but they will now get warnings when they compile and you can add documentation to point them to the new class/methods.
If you are in control of the code (especially if you're still in the design stages), you've got several options:
1. As Dr.Clap says, make your class immutable (probably best).
2. If this isn't possible, create mutable and immutable variants of your class. This is often best achieved by hanging them both from an interface.

How can I tell which object is causing my error

How can I determine which object has the lock, and for brownie points, release it?
The SP is using a view, are view read only by default in Oracle, so I can rule that out as the 'locker'?
If not, I'd like to modify with the equivalent of WITH(NO_LOCK). How can I do this in Oracle?
Error report:
SQL Error: ORA-04021: timeout occurred while waiting to lock object
ORA-06512: at "PVNG_RPT.RPT_POP_COMMON_ORDER_PATRON", line 5
ORA-06512: at "PVNG_RPT.RPT_SP_ORDER_DETAIL", line 402
04021. 00000 - "timeout occurred while waiting to lock object %s%s%s%s%s"
*Cause: While waiting to lock a library object, a timeout is occurred.
*Action: Retry the operation later.
Many thanks
DC

That's the insert statement.....
INSERT INTO
Ahaaaaaaa,
I have investigated moere and it looks like one of my American colleagues has been tinkering.
I see RPT_POP_COMMON_ORDER_PATRON_1 and RPT_POP_COMMON_ORDER_PATRON_2 in the object tree.
I've dropped _2 - Fine
I'm trying to drop _1, but that's having a really good think about it......>= 3 mins so far.
So, I guess that that points to RPT_POP_COMMON_ORDER_PATRON_1 being the culprit iof the lock, hence why it is struggling to be dropped.
How can I drop a proc that has locks, essentially saying, "I don't care what you're doing - I want you out of my database and take your locks with you!". :)
Thanks all

How can I find a bapi for perticular tcode?

hi,
How can I find a bapi for perticular tcode?
Thank you
ASHOK KUMAR

HI Ashok
If you mean that you need to know what BAPI's a particular tranx uses, which I can only assume that's what you mean, then you should access the code behind the transaction and search for 'CALL'. That normally is the standard method that think that most people use.
Suppose you want to find the bapi for creating a sales order, you usually use transaction VA01 for this.
<b>1. Find out the package of the transaction.</b>
Start Va01 go to system --> status.
Double click on transaction
Package is VA
Open this package in SE80
Open business engineering-->Business object types
Find the BO which sounds the most appropriate
I would suggest BUS2032 Sales Order
Double click.
Open methods.
Find the released method with from data or something similar in the name
, Createfromdat2
Position the cursor in it and click the program button
Scroll down to find the bapi used in this method
With this way you can also find out programs and FM's
<b>2. Start va01 go to system-->status </b>
Double click transaction VA01
Double click on package
Read the application component. (this is SD-SLS Sales)
Then open the transaction BAPI
Sales and distribution>Sales>sales order
createfromdat2

How can I remove an object using Photoshop Elements 7?

How can I remove an object using Photoshop Elements 7?

You could probably use the 8 point garbage matte in this situation. I personally think the 8-point garbage matte is a bit cumbersome, but it should get the job done.
1. Use the Razor Blade tool to place a cut before and after the shot with the bottle.
2. Select the bottle clip.
3. Press and hold Shift + Option, then drag the bottle clip up one track. This should create a duplicate clip directly above your original clip. (I'll refer to this duplicated clip as bottle2.)
4. Locate the 8-point Garbage Matte filter and apply it to bottle2.
5. Locate the Gaussian Blur filter and apply it to bottle2.
6. Control click bottle1, and uncheck the "Clip Enable" setting from the shortcut menu. This will disable that clip.
7. Double click bottle2 to load it into the Viewer. Then select the Filter tab.
8. For the Garbage Matte filter, you'll notice 8 rows of numbers, these are the current locations for the control points, which you should be able to see in the Canvas. Start with point #1, and click the "+" button in the filters area, then in the Canvas click and drag to move the point. When you release the mouse button, you'll need to reclick the "+" button in the filters tab. Repeat these steps until you've isolated the bottle.
9. Feather the edge of the matte.
10. Adjust the Blur amount.
11. Reenable bottle1. Playback the clip and make any necessary adjustments.
Depending on your experience with Motion, you might also want to try sending bottle1 to Motion, then use Motion to control the layering.
