What is Iterator? and Why is it used?

Hi,
I am newbie to BSP and ABAP, and came across iterator while going through some topic.
I used iteration process to display the values in the view in a table,
Is it some way similiar to it with different approach?

Hi,
Iterator is to design each and everycell in your table in different format and to design your table that and end your can change what ever he wants in the table and saves the data changed.
You can disign your tableview like it has a dropdown in one column, input field in one column and image in on column and link in one column like that.
Check the below links..

What happens to the while loop iteration counter if it runs unchecked?

I want to use the iteration counter to initialise a value on the first loop of a while statement. ie i = 0, x = 100. Fine. The application I am building will be left to run for weeks or months on end without stopping (hopefully :¬)). What happens to the iteration counter in this situation? Does it reset to 0 or what? I don't want it reinitialising any values while the loop is running other than when it starts.
I set up a while loop to try to figure out what happens and the iteration counter stops at 2147483648 which is 2^31 - 1.
Any help would be appreciated,
Thanks,
Niel.

It might be something you already looked at, but perhaps it's an option to perform the initialization outside (before) the while loop. That way it will be initialized correctly only once, no matter what the iteration counter does.
Of course if you need the counter for other purposes than initialization you might have the same problem...
Note that a lot of the timer functions also overflow after a certain time (I believe 24 or 48 days?) so be careful running very long loops (but you already knew that probably).

Problem extracting SOAP XML payload using pl/sql

I was wondering if I could get some help on extracting the address matches that are returned from the Web Service I am consuming. This is the first time I have dealt with XML and web services. I'm using Oracle 10.2.0.1.
The response I’m getting back returns 4 address matches (shown below against n2, n4, n6 and n8) which is:

SELECT extract(value(xmlseq), '/Errors' , i_xmlns) vi_errors
,extract(value(xmlseq), '/Warnings' , i_xmlns) vi_warnings
FROM TABLE(xmlSequence(extract(i_xml, '/GetAddressSearchResponse/ns1:ResponseHeader' , i_xmlns))) xmlseq;
i_xml that is passed in is an XMLType converted from a CLOB which is the response from the web service:
v_xml_response := XMLType(i_response);
i_response is the SOAP package above with the following done on it:
-- Strip the unnecessary SOAP XML envelope from the response
v_xml_resp := XMLType.createXml(o_response);
i_response := v_xml_resp.extract('/soap:Envelope/soap:Body/child::node()'
,'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"').getClobVal();
i_response is defined with a type of CLOB.
i_xmlns that is passed in is: 'xmlns:ns1="' || i_xml_namespace || '"' where i_xml_namespace is: http://aplt.nzpost.co.nz/schemas/search
My cursor that tries to get the address details returned is:
CURSOR c_xml(i_xml IN XMLType, i_xmlns IN VARCHAR2) IS
SELECT extract(value(xmlseq), '/ResultRecord/AddressDetails/Postal.PostBox.Number/text()' , i_xmlns).getNumberVal() box#
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Thoroughfare.Number/text()' , i_xmlns).getStringVal() street_number
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Thoroughfare.Name/text()' , i_xmlns).getStringVal() street_name
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Locality.DependentLocality.Name/text()' , i_xmlns).getStringVal() suburb
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Locality.Name/text()' , i_xmlns).getStringVal() town_city
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Postal.PostalCode.Number/text()' , i_xmlns).getStringVal() post_code
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Postal.PostOffice.Name/text()' , i_xmlns).getStringVal() box_lobby_name
,extract(value(xmlseq), '/ResultRecord/AddressDetails/Postal.PostRoute.Name/text()' , i_xmlns).getStringVal() rd_number
FROM TABLE(xmlSequence(extract(i_xml, '/GetAddressSearchResponse/SearchResults' , i_xmlns))) xmlseq;
This is not correct because it doesn’t select anything. The i_xml parameter passed in is the same as above however the i_xmlns parameter that is passed into this cursor is different. It’s currently passed in as:
'xmlns:ns2="urn:nzpost:schemas:xAL:3.0"'
Which matches what is returned in the soap message (first the first address match returned):
<ResultRecord Type="URBAN">
<ns2:AddressDetails
xmlns:ns2="urn:nzpost:schemas:xAL:3.0">
I'm calling this cursor in loop as follows:
for r_cu in c_xml(v_xml_response, v_xml_namespace)
loop
dbms_output.put_line('***** test12 - ws_avs_clients - IN LOOP - delete/insert nzp23_address');
Nothing gets returned.
Firstly, I’m not sure how to cater for n2, n3, n4, n5, etc which are the namespaces returned and incremented for each address match.
I’m also wondering if my cursor should be changed to something like:
CURSOR c_xml(i_xml IN XMLType, i_xmlns IN VARCHAR2) IS
SELECT extract(value(xmlseq), '/Postal.PostBox.Number/text()' , i_xmlns).getNumberVal() box#
,extract(value(xmlseq), '/Thoroughfare.Number/text()' , i_xmlns).getStringVal() street_number
,extract(value(xmlseq), '/Thoroughfare.Name/text()' , i_xmlns).getStringVal() street_name
,extract(value(xmlseq), '/Locality.DependentLocality.Name/text()' , i_xmlns).getStringVal() suburb
,extract(value(xmlseq), '/Locality.Name/text()' , i_xmlns).getStringVal() town_city
,extract(value(xmlseq), '/Postal.PostalCode.Number/text()' , i_xmlns).getStringVal() post_code
,extract(value(xmlseq), '/Postal.PostOffice.Name/text()' , i_xmlns).getStringVal() box_lobby_name
,extract(value(xmlseq), '/Postal.PostRoute.Name/text()' , i_xmlns).getStringVal() rd_number
FROM TABLE(xmlSequence(extract(i_xml, '/GetAddressSearchResponse/SearchResults/ResultRecord/ns2:AddressDetails' , i_xmlns))) xmlseq;
However I couldn’t have the ns2: before “AddressDetails” because this gets incremented. I don’t think I can also have the i_xmlns namespace parameter passed in as 'xmlns:ns2="urn:nzpost:schemas:xAL:3.0"'
because the ns2 gets incremented for each address.
I'm looking for any examples of pl/sql code that extracts the addresses from the SOAP message returned like I’m trying to do?
Any help would be much appreciated.
Thanks,
Brad

You can find some examples in both the {forum:id=34} and {forum:id=75} forums. Just search on soap:Envelope or soap:Body and you should get some hits back.
Since you are using 10.2, you will want to use XMLTable instead of TABLE(xmlSequence(extract as XMLTable is the direction Oracle is going. As for ns2:, ns4: it doesn't matter what namespace prefix you use in your XPath statement as long as all the prefixes resolve to the same namespace.
Here is a starter piece of code that puts all that together for you.

Foreach equivalent in java

Hi all,
I am doing some conversion process from C# to java. I am struck with c# foreach statement.
Here I give the coding,
foreach (MapFieldInfo item in Fields)
if (item == null)
continue;
if (item.Field.Equals(fieldInfo))
exp = item.NewExpression;
break;
Here the MapFieldInfo in another class. I need the equivalent java for loop for this statement.
Pls could anyone help me.
Thanks in advance.
Uma

for (Iterator it = aCollection.getIterator(); it.hasNext();){
MyClass myObj = (MyClass)it.next();
// .. do stuff with myObj
}I understand that the J2SE 1.5 spec is going to add something similar to foreach to the Java language - it's really just syntactic sugar to make the code a little less verbose, though.
Also, you just know that there are going to be people using the new nomenclature that forget what an iterator is altogether and make silly programming decisions...

My database does not know of iterators

I am creating a java class in my database, and I am trying to retrieve multiple rows from a table. In the documentation I find that
#sql public iterator IteratorName(String name)
creates an iterator with which I can iterate over multiple names from the table.
the iterator is supposed to be filled with this code:
IteratorName it = null;
#sql it = {SELECT NAME FROM FILES};
for some reason when I try to compile this, I get an error saying that the compiler does not know what an iterator is.
Did I forget an import and if so, which one?

Hello,
I too have had this problem. As far as I can tell, the issue is not with import's as much as it is with getting Oracle to recognize sqlj-styled java source code directly, I think.
I worked around this by taking my source file and compiling it "outside of Oracle" using the sqlj preprocessor.
I took my Java class file (the one that contained the #-prefixed sqlj commands) and saved it with an extension of "sqlj". Then I ran the sqlj preprocessor on it. The sqlj preprocessor generated a .java file, and in that .java file, the iterator class was declared and defined. (You can pass sqlj a "-compile=false" command-line option to prevent it from also invoking the Java compiler to generate .class files. Otherwise, you will also get at least two .class files: one for the class you wrote, and another for the iterator class that sqlj generates.)
I took the generated .java file, and used it to build a "create or replace and compile java source named ..." statement that I could paste directly into a SQL*Plus buffer, and that compiled just fine.
I am still trying to determine whether or not I need to do something else to set java compilation options inside of Oracle, via the dbms_java package, in order to get Oracle to directly compile my "create or replace and compile java source named ..." statement without my having to use sqlj to generate a "plain java" source file from a "sqlj" source file.
I know that your question is several months old... have you worked out a solution in the meantime that is simpler than what I described above?

Basics navigation passing context

Folks,
I have and adf faces select-one table. having selected one row I would like to click on the submit button for this table and have it take me to another page.
The navigation is no problem but I would also like to take some values from the table iterator and use that value to restrict the iterator on the target page.
I am conceptually running into some challenges:
1. The manual I am using seems to alude to using EL expressions in the listener attached to the submit button. I have done this much and am getting row.rowKeyStr value but am not sure what the "to:" side should be. Does the listener request scope allow you to put values to a new page, or restrict an iterator or something?
2. If not request scope, does one have to create a session scope managed bean. I was not sure if I could use a request scope so I tried to create a managed bean, but when I try to set an attribute in my session the constructor never fires. I thought that ADF was supposed to handle instanciating these bean I created in the overview tab of the faces-config.xml file
3. What about other methods for passing values to other pages? Parameters? Setting some values on the target page directly?
4. And once you are at the new page how do you get at and use the value you have set to chage what the iterator brings back?
Thanks for any and all help.

OK, Shay. That is a great idea.
It looks like from a quick look I had on this document is that they are using a session bean. They called it userState.
I was heading down that path...I just had a few holes to fill in. I will peruse this document and find out more.
When I tried to create and use a session bean it was giving me an error that seems to indicate that the bean is not getting initiallized or constructed. Have you ever had such issues when creating managed beans in the session scope? Any scope?

Threads Question/Opinion

I am currently developing an application that will create a process. The process itself will be cmd.exe with parameters. The application is Swing based and so I don't lock the event dispatch thread, I created a thread that will create the process. I also know that when using cmd.exe it is important to handle the inputstream and errorstream so the whole process does not lock. The examples I've seen for handling these streams where handled in threads of their own so they could be processed at the same time. My question is this: In your opinion would it be better to handle the process and streams in one thread, or should I create one thread to create the process and 2 threads to handle the streams (1 thread for each stream)? I think the multiple threads (essentially 3 for one process) will negatively impact the applications performance, but I don't know if handling the streams in a function/method within one thread would be adequate enough to keep the app from deadlocking. Any ideas?

I had read that multiple threads can cause more
e overhead and slow performance of the application in
general. The article just said more threads=more
overhead, Fair enough. That's true as far as it goes, but I can't imagine 3 threads ever causing any detectable problem, unless each thread is something like this public void run() {
someField_++;
Thread.yield();
} It's not uncommon to have tens of threads, and I've created thousands in little dummy test programs and not noticed performance problems.
I didn't have an exact number to work with
and that was my concern. I believe the threads I was
thinking of would perform the needed actions quickly
and therefore not impact performance too much, but I
wanted to be sure. The key is that each thead does enough at one time so that the overhead of switching is small compared to the work done, but also making sure that no thread hogs the CPU for too long. If you're doing I/O, then each call to read has the potential to let another thread have a turn, I believe. Otherwise it's common to put a call to yield in your thread's main loop. Maybe every iteration, maybe every 10 or 100 or whatever, depending on what that iteration does.
If you have tasks that can be handled in parallel--indpendently of one another--or should be independent to prevent one from forcing another to wait (like reading two streams) then you should give those tasks separate threads. Once you have that working correctly, then if you have measured performance problems relating to how those threads interact or take turns (or don't take turns) then you can tweak the code to try to optimize that aspect of it.
I am teaching myself Java and its
been a bit of a haul. I appreciate the help and
information I get from these forums hence this
posting.Cool. Glad to be of help.

Import Large XML File to Table

I have a large (819MB) XML file I'm trying to import into a table in the format:
<ROW_SET>
<ROW>
<column_name>value</column_name>
</ROW>
<ROW>
<column_name>value</column_name>
</ROW>
</ROW_SET>
I've tried importing it with xmlsequence(...).extract(...) and ran into the number of nodes exceed maximum error.
I've tried importing it with XMLTable(... passing XMLTYPE(bfilename('DIR_OBJ','large_819mb_file.xml'), nls_charset_id('UTF8'))) and I gave up after it ran for 15+ hours ( COLLECTION ITERATOR PICKLER FETCH issue ).
I've tried importing it with:
insCtx := DBMS_XMLStore.newContext('schemaname.tablename');
DBMS_XMLStore.clearUpdateColumnList(insCtx);
DBMS_XMLStore.setUpdateColumn(insCtx,'column1name');
DBMS_XMLStore.setUpdateColumn(insCtx,'columnNname');
ROWS := DBMS_XMLStore.insertXML(insCtx, XMLTYPE(bfilename('DIR_OBJ','large_819mb_file.xml'), nls_charset_id('UTF8')));
and ran into ORA-04030: out of process memory when trying to allocate 1032 bytes (qmxlu subheap,qmemNextBuf:alloc).
All I need to do is read the XML file and move the data into a matching table in a reasonable time. Once I have the data in the database, I no longer need the XML file.
What would be the best way to import large XML files?
Oracle Database 11g Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
"CORE     11.2.0.1.0     Production"
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

This (rough) approach should work for you.
CREATE TABLE HOLDS_XML
        (xml_col XMLTYPE)
      XMLTYPE xml_col STORE AS SECUREFILE BINARY XML;
INSERT INTO HOLDS_XML
VALUES (xmltype(bfilename('DIR_OBJ','large_819mb_file.xml'), nls_charset_id('UTF8')))
-- Should be using AL32UTF8 for DB character set with XML
SELECT ...
FROM HOLD_XML HX
       XMLTable(...
          PASSING HX.xml_col ...)How it differs from your approach.
By using the HOLDS_XML table with SECUREFILE BINARY XML storage (which became the default in 11.2.0.2) we are providing a place for Oracle to store a parsed version of the XML. This allows the XML to be stored on disk instead of in memory. Oracle can then access the needed pieces of XML from disk by streaming them instead of holding the whole XML in memory and parsing it repeatedly to find the information needed. That is what COLLECTION ITERATOR PICKLER FETCH means. A lot of memory work. You can search on that term to learn more about it if needed.
The XMTable approach then simply reads this XML from disk and should be able to parse the XML with no issue. You have the option of adding indexes to the XML, but since you are simply reading it all one time and tossing it, there is no advantage to indexes (most likely)

PageDef.xml executables

What actually iterator object in executable node in page definition file really do?

Tracks the current row in a data collection. The ADF Model iterator binding simplifies tracking the selected row in a robust way, using row keys instead of relying on positional indicators that can change when data is refreshed and positions have changed. In concert with the ADF Faces table and multiselection components, it’s easy to work with single or
multiple selections, and build screens that navigate master/detail information.

In the case of Fail-fast iterator, if a thread modifies a collection directly while iterating over it, the iterator will thow ConcurrentModificationException . Say,
for (Iterator it = collection.iterator(); it.hasNext()) {
    Object object = it.next();
    if (isConditionTrue) {
        // collection.remove(object); can throw ConcurrentModificationException
        it.remove(object);
}As per specs,
Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception. For example, if a thread modifies a collection directly while it is iterating over the collection with a fail-fast iterator, the iterator will thow this exception.

What is best practice to iterator VO ?

Hi,
Please Let me know what is the best approach to iterator the VO.i used to do like following --
ViewObject viewObject=getTestObject();
Row[] row=viewObject.getAllRowsInRange();
for(int i=;i<row.lenght;i++)
//operation logic
}Is this correct way or the following why which was suggest by my friends yesterday night
ViewObject viewObject=getTestObject();
RowSetIterator iterator = viewObject.createRowSetIterator(null);
iterator.reset();
while (iterator.hasNext()) {
Row row = iterator.next();
// process the row here
iterator.closeRowSetIterator();Thanks

Planning Layout: 7KEA (PCA): What is attribute?

Hi,
Could anyone advise what is the attrribute during the creation of PCA planning layout?
Attribute can be either: Unit, Text Exits, Distribution Key, Action
When I click to insert an element (Shift+F4), I can have options to choose as follows:
Key figures with characteristic
Formula
Attribute
Kindly briefly advise on their features, especially the attribute.
Thanks.

Hi Rajiv,
Thanks for your reply. I can't understand you explanation.
I cannot understand from this website although it has some explanation in length.
http://allian.uclv.net/saphelp/helpdata/EN/e9/f02c7dd435d1118b3f0060b03ca329/frameset.htm
The question is, I tested:
One layout with coloumn distribution key and one without distribution key; but the result of the report is same ...
What are the distribution key or other attrubute values actually for? Any solid examples?
Under teh DK columns, there are some selectable values, like the following:
0     Manual distribution
1     Equal distribution
2     Distribution as before
3     Distribution by percentage
4     Distribute values to following no-value periods
5     Copy values to following no-value periods
7     Distribute according to number of days in period

What is Sun's answer about PCA patch manager free tool ?

Hi all,
this post aims on echoing customers'feedback.
from customers'experience it seems that smpatch from patch manager tool is suffering of a lack of reliability.
One of them moved to a new freeware called PCA-Patch Check Advanced
http://www.par.univie.ac.at/solaris/pca/
From PCA Web Site we can read:
Sun has offered various tools in the past to analyze Sun/Solaris systems for patches which are installed or missing, e.g. PatchDiag, PatchCheck, PatchPro, smpatch (see the Sun Patch Portal for details). Some of them are not actively maintained, some are huge and opaque, some don't run on older Solaris releases or stripped-down machines. None of them really made me happy. Based on PatchCheck source I implemented PCA, which gets rid of the disadvantages of Sun's own tools.
I would like to know what is Sun's position and could it be possible to integrate such a tool ?
Thanks.
Malek.

- Sun is always interested in customer feedback, and is interested in
the concerns expressed here.I'd also very muck like Sun to be interested in fixing the customers problems, which has not been done in my cases. No solution or explanation has been given to my many cases opened on smpatch, and this, even though in some cases, patches were made (months later): I was never told about them. Which makes me wonder about the point of having paid support contracts in the first place.
But since UM was developed by interns, it's no wonder there's trouble maintaining it (how do I know? I've been an intern doing Java development, and I made the exact same beginner's mistakes, not knowing to handle exceptions, leaving debug output on stdout, being unable to make proper localisation).
It's obviously not the work of experienced Java programmers. Hard to trust it...
- We do understand that opaque is bad, but one of Sun's goals is to
provide complex analysis beyond matching patches with installed
packages. This analysis and its support processes will necessarily
be somewhat opaque.What analysis are you talking about? smpatch is not even able to tell me that security fixes are available for NSS, which has been part of Solaris for years. PCA does.
And what about Studio? Why can't smpatch tell me there are patches for that, too? And why aren't free patches, that are neither recommended nor security (such as the man patches) shown by smpatch when running without a contract?
- We are interested in the concerns surrounding stripped-dow
systems, and are considering a "light" version of our tools that would
support minimal systems. However at this time there are no plans to
release a light version.And what about systems without a network?
And what about not forcing me to read and agreeing to a, abusive license agreement, which can't even be printed, nor shown full screen (5 lines at a time!)?
And, please, can you explain me why I should agree to respect Reuters so-called intellectual property? What does it have to do to with keeping my systems up to date reliably and easily? Is it a competition between Sun and Microsoft to put the most ludicrous licenses on line?
Anyway, I'm sure Solaris 11 will introduce some new bloated offspring of the PatchProManagerUpdateConnection family, so I'm not holding my breath. Rather than repeat this experience again and again, I'll stick with PCA.
