Max number of chars in process message MSEL?

Hi, what is the max number of characteristics can be used in process message category's MSEL table? Right now, I am using more than 99 characteristics and I get a short dump DYNPRO_FIELD_CONVERSION. Is it really limited to 99 characteristics and if it is true, is there an OSS note to change it to allow more than 99?
Thanks and points available

Please make sure that you build a
multithreaded program first (check with ldd).
If anyone can tell me the maximum number of threads per process I would
really appreicate it.
Also the maximum number of open files per process. It depends on the architecture (x86/SPARC), OS version,
64 or 32-bit, /etc/system, shell limitations (/usr/bin/ulimit) ...
Search for "rlim_fd_max / rlim_fd_cur" on docs.sun.com too.

Alter table reaching the max number of char 4000, CLOB? NCLOB?

I have a column is a table defined as a VARCHAR2(4000)
I try to alter the table
alter table sybaapc
MODIFY SYBAAPC_EXTRACURRICULAR VARCHAR2(5000)but it give me this error
ORA-00910: specified length too long for its datatype
I want the users to be able to enter more information on that column.
It seems that 4000 is the max we are in Oracle 10g
can I changed to CLOB or nclob, we already have data in that table?
What are the implications of changing it to clob or nclob,

Thats becuase the maximum character length for a table column is 4000.
Alternatively you can:
SQL> create table test_1 (col1 VARCHAR2(4000))
2 /
Table created.
SQL> insert into test_1 values(RPAD('*',4000,'*'));
1 row created.
SQL> commit;
Commit complete.
SQL> alter table test_1 modify (col1 clob);
alter table test_1 modify (col1 clob)
ERROR at line 1:
ORA-22858: invalid alteration of datatype
SQL> alter table test_1 add(col2 clob);
Table altered.
SQL> update test_1 set col2 = col1;
1 row updated.
SQL> commit;
Commit complete.
SQL> alter table test_1 drop column col1;
Table altered.
SQL> alter table test_1 rename column col2 to col1;
Table altered.
SQL> desc test_1
Name Null? Type
COL1 CLOB
SQL>
SQL> select * from test_1;
COL1

Restricting TEXTAREA component to lines.

Hi All,
I wanna restrict user entry to certain no of lines in my
textarea component. Ho can i do this? I havent seen any relevant
API's for this in the help. Should i do this totally programatic
way?? Can anyone give me a hint?...
I can restrict characters and the requirement spec needs to
restrict lines too, say 16 lines.
Regards
Roshan

Hi Kglad,
I have to restrict my textArea component to 16 lines. Even if
a single char is represented per line, it sould take only 16 lines
whatsoever.
I have restricted the no of chars to 572, which was there in
the requirement. Now i'm left with this probs.
Hope I can get it done..

Limit number of chars per line

Hi ,
how to limit the number of chars per Line in a textArea or RTFEditableText?
I have to do the following:
Allow 25 Chars for first line,
any other line should have max. 28 chars.
First line should have a bold font.
Not an easy thing..
I tried to use a textarea fpr input and put the text into a datagrid in the textarea.change() event.
This works, but I lose a lot of the standard features of the textarea (hyphenation etc.)
The idea is to use only the textarea or a RTFEditor for applying the rules mentioned above.
Thanks
thorsten

extend PlainDocument class to restrict the number of characters per line.
Set this class as model to TextArea.
Below is a class which does this. May be its useful
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
public class FixedNumericDocument extends PlainDocument {
private int maxLength = 9999;
private String max="";
public FixedNumericDocument(int maxLength) {
super();
this.maxLength = maxLength;
//this is where we'll control all input to our document.
//If the text that is being entered passes our criteria, then we'll just call
//super.insertString(...)
public void insertString(int offset, String str, AttributeSet attr)
throws BadLocationException {
if (getLength() + str.length() > maxLength) {
return;
else {
try {
//check if str is numeric only
int value = Integer.parseInt(str);
//if we get here then str contains only numbers
//chk if it is less than 65535 so that it can be inserted
super.insertString(offset, str, attr);
catch(NumberFormatException exp) {
return;
return;

Max number of records in an internal table

Hi,
Can any one tell me what is the Max Number of records we can get into an internal table.
if you have any link of sap help on this please FWD.
thanks in Adv.

Lakshmikanth.T.V

Hi lakshmikanth,
Internal Tables as Dynamic Data Objects
Internal tables are always completely specified regarding row type, key and access type. However, the number of lines is not fixed. Thus internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries. The line types of internal tables can be any ABAP data types - elementary, structured, or internal tables. The individual lines of an internal table are called table lines or table entries. Each component of a structured line is called a column in the internal table.

keerthi.

Max number of items exceeded?

I am trying to develop a questionaire like application. Most of the logic is stored inside pl/sql functions (that is retrieving the previous or next question with possible answers and answer-types, like, eg. radiogroup, select-list, textarea, ...) while all of the questions and respective possible answers are kept inside a collection. In processing the answers after submit I store given answers inside the same collection, basically by nullifying all possibly previously given answers for the current question and then looping through eg, g_f01.count to refill. The entire application remains on the same page, showing eg., in one 'frame', one or two questions with say 7 checkboxes and two textareas.
Everything seems to work fine, I can go forward and backward and will find new questions or ones that already have been answerd, but!!...
after the 50st item (answer), that is after I reached the 50st radiogroup, checkbox or textarea, new checkboxes or radiogroups even though shown the resulting values will not be stored inside the collection anymore.
generating the page i use:
htp.prn(apex_item.radiogroup(p_idx => 1, p_value => c2.a_id, p_selected_value => c2.qa_id, p_attributes => 'id="P2_QUEST_' || i || '"'));
and in processing correspondingly ...
FOR i IN 1 .. apex_application.g_f01.COUNT
LOOP
FOR c2 IN
(SELECT seq_id,
c001 q_id,
c002 a_id,
c012 qa_id
FROM apex_collections
WHERE c001 = to_char(p_q_id)
AND collection_name = 'ANSWERS'
AND c002 = apex_application.g_f01(i))
LOOP
apex_collection.update_member_attribute(p_collection_name =>
'ANSWERS', p_seq => c2.seq_id, p_attr_number => '12',
p_attr_value => c2.a_id);
END LOOP;
END LOOP;
to me I only use f01 ... f04 say, ... Is it possible that I still hit the max of 50 page-items?
Regards

Bug? using MAX() function on char(1) column returns something larger

details:
-- we have a complex nested query, where we are essentially returning the max() value into a variable
-- the max() function is being used on a char(1) column
-- where MAX() is part of an inner select, we have started getting
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
errors.
SELECT MAX(X) INTO var FROM ... works in 9i and 10g
SELECT X INTO var FROM (SELECT MAX(X) X FROM ... worked in 9i, does not work in 10g!
-- We never had problems with the code until upgrading to 10g release 2.
-- the Solution is to cast the final value with TO_CHAR(). The cast MUST be done at the outer most point of the select:
SELECT TO_CHAR(X) INTO var FROM (SELECT MAX(X) X FROM ... works
SELECT X INTO var FROM (SELECT TO_CHAR(MAX(X)) X FROM ... causes an error!
The following script demonstrates the issue, and includes the solution:
* October 3, 2006
* Possible SQL bug introduced with Oracle 10G
* Natalie Gray DBA/Developer, Environment Canada
* Description:
* Have discovered a problem with using the MAX() function

I certainly looks like a bug, but you should raise an iTAR on Metalink since Oracle does not monitor this forum.
I was able to replicate your results on my 10.2.0.1 database.
There is an easier workaround than yours. Try
ALTER TABLE sql_bug_test MODIFY (z VARCHAR2(1));That seems to eliminate the problem on my instance.

but i get the error "Inconsistent datatypes: expected NUMBER got CHAR error" when i put p.rank||'/'||p.cnt
How can that be solved.
ORacle version is 10g.

Taken from the documentation of the CASE expression:
"For a simple CASE expression, the expr and all comparison_expr values must either have the same datatype (CHAR, VARCHAR2, NCHAR, or NVARCHAR2, NUMBER, BINARY_FLOAT, or BINARY_DOUBLE) or must all have a numeric datatype. If all expressions have a numeric datatype, then Oracle determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that datatype, and returns that datatype.
For both simple and searched CASE expressions, all of the return_exprs must either have the same datatype (CHAR, VARCHAR2, NCHAR, or NVARCHAR2, NUMBER, BINARY_FLOAT, or BINARY_DOUBLE) or must all have a numeric datatype. If all return expressions have a numeric datatype, then Oracle determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that datatype, and returns that datatype."
You need to use the same data type for all your expressions. If you want to return a string, then you need to convert the remaining numbers explicitly to strings. E.g. you could try something like this:
CASE
             WHEN code = 'MDN' THEN
                       to_char(max(case when p.m_date = v_prev2_yr_mon and p.period_type = '1M' then p.mdn /100 else null end), 'TM')
             WHEN code = 'QRT' THEN
                  to_char(max(case when p.m_date = v_prev2_yr_mon and p.period_type = '1M' then p.quartile else null end), 'TM')
             WHEN code = 'PCT' THEN
                  to_char(max(case when p.m_date = v_prev2_yr_mon and p.period_type = '1M' then p.pct_beaten / 100 else null end), 'TM')
             WHEN code = 'RNK' THEN
                       case when (p.m_date = v_prev2_yr_mon and p.period_type = '1M' and p.rank is null and p.cnt is null)
                    THEN
                                   to_char(P.RANK, 'TM')
                    else
                                    p.rank||'/'||p.cnt
                    end
             ELSE NULL
             END CASE I see another potential issue, you're mixing aggregate functions with non-aggregate expressions, this can only work if these non-aggregate expressions are part of the group by clause, but you haven't posted the complete statement so I can only guess.

Dynamic linking within TextArea component

how can i include an MC or button inline within the HTML text
of a TextArea component -- and also have that object link to an AS
function? i want to have icons within the text of my TextArea that
open pop-up windows within the Flash application (MC linkage).
is this possible?
is asfunction used? if so how?

Well if you are still interested in using a text component
instead of a Button the way you would go about this is using
textWidth. Here's how I've done it before using a text / label
whatever you want that shows text.
// => Set our text we got from database
myText.text = "This is the text I got from the DB";
// => Validate it so that way we make sure we get right
numbers
myText.validateNow();
// => Find out how wide our text really is.
var textWidth:Number = myText.textWidth
// => Reset the width of our text component and add 20 for
a little buffer
myText.width = textWidth + 20;
Now my suggestion is if your going to be dynamically creating
these on the fly from a database call you throw it into a method /
class and have that do all the work for you so all you have to do
is pass the text to it and it resizes itself based on the example
above.

How can i display image in mx:TextArea Component?

I found display img tag in htmlText of mx:TextArea component
is very difficult in Flex Air
I new a simple air project in flex builder, put the code
below in it, i put a glad.png file in the src folder, every thing
is OK, when i run it, image cannot be displayed. why this happend,
I search the google for the solution, it seems there is a bug in
air, and told me to use mx:HTML coponent, but that component still
can not display img tag.
could any one help me with this?

home page.

</mx:htmlText>
</mx:TextArea>

I ran into a similar problem and wasn't able to find a way to have regular Flex components (like Text and TextArea) display <img> tags in their htmlText. Everything works find in a web-based Flex application, but once the same code was used in AIR, the images just wouldn't display.
I changed my display to use the mx:HTML component and everything worked fine (I was using only external images).

How can I convert a number i.e ascii number to char in javascript.
Quite simple: By asking in a forum that deals with javascript and not with java.

How can I access the content of a textarea component?

I'm trying to use a javascript form editor in my jsf project.
The form editor writes to an html <textarea> component.
The jsp page looks like this:
<div style="height: 336px; left: 0px; top: 0px; position: absolute; width: 672px">
<script language="javascript" type="text/javascript">
tinyMCE.init({
mode : "textareas",
theme : "advanced",
</script>
<textarea cols="50" name="content" rows="15">This is some content that will be editable with TinyMCE.</textarea>
</div>
The content of the <textarea> component is changed with the editor.
What I need to do is capture that content after it has been edited.
How can I do that??
Thanks

I have a similar problem. When I try to watch the rented movie a pop up says "Cannot Open: The content is not authorized" What exactly is the problem. I'm not in the US at the current moment. I'm in France. But that shouldn't be a problem right?

A few questions about using an XML file to add text into a TextArea component set as html

I'm using AS2 in Flash CS3.
I have a TextArea component in the stage that's loading its text from an XML and I've been able to use the ul and li tags to create lists. However, when I try to include a nested list it just inserts a line break between the nested list and the main list rather than indent it further. Is there a solution for this issue?
Failing that, how would I be able to add non-breaking spaces into the XML so they will render inside the TextArea component? I've tried and   without success. I scoured the net for some help with this and found some information about modifying the font embedding xml file with a new entry for the non-breaking space and that didn't work either, so that leaves me somewhat stumped.

flash doesn't handle nested lists (as you now know). you can work-around that limitation using css and creating your own indent styles. css have a marginLeft property you can use.
