Track Data size limits?

I noticed yesterday that the Track Data (Send) part of the
LMS (Send Data) (ie the lesson data variables) must have a maximum
total limit of data allowed to be transferred to the VLE
(blackboard) and back.
I am saving text entry answers in my module each answer as a
lesson data variable. However If you fill up the first activity,
when you go back into the module and add more info or info to
another activity then nothing gets saved. I presume this is because
there is a maximum ceiling of data that can be stored in these
variables. This is very worrying as we MUST be able to store
lengthy answers for all the activities and assessment questions and
the LMS MUST store these and send them back to
the module when the user returns. otherwise we will need to
redesign the module so that we can get this working some
alternative way!
From a count, it seems there can be a maximum of 1079
characters stored before it stops you sending any more data.
Any initial thoughts or better ways we can store text entry
answers via LMS KO, SCORM and Blackboard VLE?

Custom fields won't work, unless it's his own LMS which he
can modify at
will (which it isn't, in this case). And even then, that
would totally
break the SCORM spec - so his course couldn't be used in any
other LMS.
suspend.data is the only field available for random data.
There are
others, but they are pretty limited; interaction.data can't
be read
from, objective.data has available space only in the ID
field,
student.data is 2004 only (and maybe not readable).
The issue here is definitely Authorware and the Send Data KO.
I posted
to the AwareList with the same problem months ago. The Send
Data KO tops
out at about 1080 characters for some reason.
And even if that is overcome (which it can be with custom JS
functions
in the HTML), the suspend.data field is still limited to 4096
characters.

textarea data size limits

We are using ColdFusion 8 and MS SQL Server 2005. We have a
form with a <textarea> tag into which users are cutting and
pasting large documents. When the form is saved, the text is
truncated at 32,000 characters. We are using the POST method and
saving to a column of ntext datatype (maximum of 1,073,741,823
characters). We do not do any programmatic data manipulation prior
to saving - we just update using <cfquery>. We have tried
using various "cflsqltype" settings with the same result: we
succesfully enter more than 32,000 characters in the
<textarea> (confirmed with JavaScript) and then only get
32,000 characters in the database.
This occurs with various versions of IE, FireFox, Opera and
Safari, so it doesn't appear to be a browser issue. We have tried
it on Windows 2000, Windows XP Pro and Windows Vista, so it's not
particularly OS related. We have tried it on IIS 6 and IIS 7 with
the same results, as well as SQL Server 2000 and SQL Server 2005.
The only thing left seems to be some data incompatibility between
ColdFusion and SQL Server.

The CLOB was the answer - it wasn't checked! The LongText
Buffer setting is now at 64,000 and my test works great. We'll
probably have to up that a little more, but we don't need
encyclopedias stored! Thanks for your quick help.

HTML form size limitation

It's about a size limit. When a HTML form is submitted, there is a size limit of how much information can be sent to the server. I'm talking about using the POST submission (as opposed to the GET submission).
It used to be that the HTTP protocol specified a limit of 8K. The new version of the protocol now says there is no limit imposed and it is up to each server manufacturer to set its own limits.
Can anybody help?

So what is the data size limitation of Oracle HTML form? Does anybody know that? or if there is a document can be referenced?

What are the limitations in terms of data size or performance while using csv or text file as datasource?

Also what are the limitations in terms of data size or performance related issues while using csv or text file?Is it the best practice to use csv , text file to use as a datasource to improve performance?Please Advice....  

Hi,Create Same Data Input for CSV and Text File ,Create 2 different reports one for CSV and One for Text ,run them one you have done that.Go to Report Menu and Select Performance Information .Use the Data in that to check which one is good datasource to improve performanceCheersRahul

How to Get Around the Memo Size Limitations in CR ?

I am Using Crystal Reports 2008, SQL Database and ASP .Net Visual Studio 2010 for Team Foundation with Crystal Viewer embedded in a web page. All current update and patches area installed.
Database has Memo Fields up to 164000 characters in length. Viewer show fine, but with the reports that have been designed to print this information, only seeing part of the Memo field.
This happens with both RTF, Text and HTML formatted data from within the database field.
I have read that there is a limitation on the size of a Memo field that Crystal Reports will print (65,534).
I actually received an Crystal Reports error box when i try to concatenate multiple substring fields as a formula.
Does anyone have any suggestions or ideas on a work-around ?
Due to legal considerations, this data has to be output as it was input, so it can't be hacked. It can be parsed and again merged but I really donu2019t want to try and write SQL procedures to parse HTML code into readable multiple pieces based on variable length tags with large memo fields.
Please offer any and every suggestion,
Thanks to all ! !

Iam passing an array of objects from Java to the C
file. The total size of data that Iam sending is
around 1GB. I have to load this data into the Shared
memory after getting it in my C file. Iam working on
HP-UX (64-bit). Everything works fine for around 400MB
of data. When I try to send around 500MB of data, the
disk utilization becomes 100%, so does my memory
utilization and I get a "Not enough space" when I try
to access shared memory. I have allocated nearly 2.5GB
in my SHMMAX variable. Also, I have around 45GB of
disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?

Nio ByteBuffer and memory-mapped file size limitation

I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
try
String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
0, 100000000 );
rwChan.close();
catch( Exception e )
e.printStackTrace();
I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
Thanks in advance for any input.

What is the recommended way to obtain tracking data from carriers post XSI

We currently run an old version of SAP Business Connector. We are in the process of migrating all interfaces off BC onto PI. The one remaining interface we have problems is the XSI (Express Delivery Interface) interface we have with ECC06 and UPS via the BC server. The interface works but is not stable and we would like to decommission it if we are able.
I'm not 100% clear but it appears that XSI is no longer the recommended solution for obtaining tracking data from carriers. What is the recommend method today? We'd be happy to use a PI or ABAP solution but would prefer a standard solution that was supported by SAP and UPS.

Using Time Machine is the simplest way to back up.

How is the drive formatted?
If it's DOS/FAT32, you can only size file sizes up to 4GB.
If you are using it on a Mac only, format it Mac OS X HFS+.

Why is Data Size in QT inspector twice the size of the file?

I am not asking this to save space. I am just curious. When playing a dv (captured from camera) clip, I notice that the QT inspector shows data size about twice the size of the dv clip size in file system. Is it because the dv is compressed and QT decompresses?
Actually, on clip in QT shows 22GB which is impossible to fit on a miniDV tape.

You'll notice that a DV Stream file has two tracks (audio and video) of the same size when viewed in QuickTime Movie Inspector or the Movie Properties window of QuickTime Player Pro.
Obviously the audio track shouldn't be the same size as the video track. There are separated from the single stream to allow editing.

Input file size limition in File Reader Adapter

Hi,
We have a File Read Activity(using File Reader Adapter) which works on a Polling model. Whenever a input file is found in a designated directory it invokes our BPEL web service. During load testing we found out that if input file size exceeds 7 MB then we get "insufficient heap space" error. We found a reference to this size limitation in http://download.oracle.com/docs/cd/E11036_01/integrate.1013/b28994.pdf which has below lines..
"Files that are 7MB or larger in size cannot be delivered. As an alternative, you can debatch large files (if they have multiple messages), and publish these files in messages of size less than 7 MB. This alternative is applicable only to structured files (comma-delimited or fixed position), which contain more than one message. It is not applicable to binary or XML files."
Our customer will have the data in XML format and the size of the files will be pretty huge(running into 49, 69 MBs). Do we have any workaround here or we are left with no option but to ask the customer to split the files and load it? The later option is currently difficult one for the customer since when split there is a possibility of XML becoming invalid. Any pointers in this issue is appreciated.
Thanks!
Balaji

Hi,
BPEL can not process more than 7 MB size xml structred file. but,debatching will work for xml files also provided if the file has repeated multiple structures (means multiple repeated root elements).

JDBC:KPRB string size limits-NEED HELP!

Hello All.
Please, I need your help.
I have the problems in Oracle 9.2.0.6 with stored java and jdbc:kprb internal driver.
I try to put string(more than 32K) into LONG-type field using following java class:
import oracle.sql.CLOB;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.io.Reader;
import java.io.CharArrayReader;
public class LongTest {
public static void insertLong()
throws Exception {
Connection con = DriverManager.getConnection("jdbc:default:connection:");
//generate large string
StringBuffer stringBuffer = new StringBuffer();
for (int i = 0; i < 100000; i++) {
stringBuffer.append("qwerty");
String st = stringBuffer.toString();
//put large string to long-type field
PreparedStatement pst = null;
try {
pst = con.prepareStatement("insert into TEST_LONG (ldata) values (?)");
pst.setString(1, st);
pst.execute();
} finally {
if (pst != null) {pst.close();}
But I get error from jdbc:kprb about limitation of data size for this type(LONG).
But it works well in oracle 10.2.0.1...
Has anybody a solution of how to do this in oracle 9.2.0.6???
thanx!

HTML Editor size limitation?

Hi, 
I'm using Apex 3.1 on Oracle 10g... 
Is there a size limitation on the number of characters in the HTML Editor? 
We have a Report/Form combo for a column. clicking on the "Edit" Link from the Report takes you to the Form where you can edit it. 
The corresponding database column is of type LONG. I see the data in the report, but clicking on Edit gives me an error - 
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small 
I've tried switching from CLOB to LONG for the column's datatype, but both fail to open the Form. 
If I change the Item type to "Text Area", the LONG column works, but I do need it as an HTML Editor... 
Thanks for any help!

Size limitation for system-jazn.xml

Hi helping hands,
In sytem-jazn-data.xml and users-properties.xml , I want to include 1 lakh users. When I tried 1 lakh users,the bpel engine is not getting restarted.
However I tried with 50k list of users, it works very fine.
Is there any file size limitations are there for those 2 files.
Could you suggest me an idea.
Regards
Viki

Hi,
I had to lookup what 1 lakh means and it appears to be 100.000? You should not put that many users in the system-jazn.xml file, not even 1000. It results in poor performance. You definitly should switch to OID or any other third party ldap server if you have that many users.
Kind Regards,
Andre

Max heap size limits

I've been looking around for information on the max heap size limits on Sun's JVMs but can't seem to find any information. Just by testing, it seems like the max heap size for Windows 2000 can vary from 1.3G to 1.6G depending upon the machine (JDK 1.4). Does anybody know where I could find actual documentation that describes the limits for Sun's VMs on Windows (2000 and Advanced Server), Linux, and Solaris? I'm about to file this as a documentation bug against the JDK.
God bless,
-Toby Reyelts

There was an older thread in the forums that had some info on this - my quick search failed to locate it, ypu might want to spend some time looking. The basic problem is memory space fragmentation by the OS, where the OS locates items in memory and effectively constrains heap growth to the unfragmented area that the heap starts in.While there may be more "unused" memory, it's not contiguous. There is also some info in MS's MSDN data regarding this condition, with information on the various OS's. I think Linux has a similar "condition".
