Record store size?

are there any limitations to which a record store can expand?
or to maximum number of record store a application can create?
thanks

Thanks for replying.
I have found that older phones (mainly MIDP 1.0) have fixed size of space allocated to application. Say, on Nokia 6610 the application cannot take more than 20400 bytes.
But, newer phones (MIDP 2.0) like Nokia 6230,3220,6600 have shared storage space and an application can consume all that is available.
This implies we cannot make an application which requires more than ~19KB data on older phones.
It would be great if some one could further throw some light on this issue?

Record Store help!!!!!

When I delete a record store I find that I have to quit the midlet application completely and then re-enter it before the midlet recognises that the record store has been deleted. What im saying is that the record store is where the data for a list of names is retrieved from. When i delete the record store and take a look at the name listing I still find the list is populated with the deleted record store names??? Its only when i exit the midlet and the re-enter it that i find the name listing is properly updated i.e. not displaying any names.
Can you please tell me, anybody, why this is and is there a way that i can reset the midlet so that it recognises the change in the record store when it is deleted without having to exit the midlet.
Thanks.

So you can see that a player is added to the record store, but when i try and take a look at a list of players that I have constructed the player just added is not present??? Its only when I exit the MIDlet completely and then re-enter it that the player list is fully updated with the new player.

How can I convert string to the record store with multiple records in it?

Hi Everyone,
How can I convert the string to the record store, with multiple records? I mean I have a string like as below:
"SecA: [Y,Y,Y,N][good,good,bad,bad] SecB: [Y,Y,N][good,good,cant say] SecC: [Y,N][true,false]"
now I want to create a record store with three records in it for each i.e. SecA, SecB, SecC. So that I can retrieve them easily using enumerateRecord.
Please guide me and give me some links or suggestions to achieve the above thing.
Best Regards

Hi,
I'd not use multiple records for this case. Managing more records needs more and redundant effort.
Just use single record. Create ByteArrayOutputStream->DataOutputStream and put multiple strings via writeUTF() (plus any other data like number of records at the beginning...), then save the byte array to the record...
It's easier, it's faster (runtime), it's better manageable...

Help needed in deploying a record store

i have to deploy a MIDlet suite over OTA my MIDlet is not able to access Record store which is in /home/Rizwan/WTK2.2/appdb/DefaultColorPhone/record.db how
Jaring is achieved
Thankx in advance

You can't jar and deploy it. You'll need to fill the RMS from some file in your jar the first time you start your midlet.

Getting Problem after Deleting a record from Record Store

I am trying to create a simple application for mobile device. This application storing some records. I used RMS for this. These records i show in a list. But i tried to show list of records after deleting any record then list shows only prior records of deleted records n then shows exception as
Recordsjavax.microedition.rms.InvalidRecordIDException
The code i written as follows
For storing data
public void storeExercise(String EName, String Etime)
try
//System.out.println("AAAA");
recordstore = RecordStore.openRecordStore("Test3",true);

outputdataStream.flush();
outputRecord = outputStream.toByteArray();
recordstore.addRecord(outputRecord, 0, outputRecord.length);

outputStream.close();
outputdataStream.close();
zlist.append(EName+Etime, null);
display.setCurrent(zlist);
catch (Exception error)

for (int x=1; x<= recordstore.getNumRecords() ; x++ )
recordstore.getRecord(x, byteInputData, 0);
if (x == index)
recordstore.deleteRecord(index);
//x--;
inputStream.reset();
break;
inputStream.close();
inputDataStream.close();
catch (Exception error)
System.out.println("Exception in Deleting Records"+error);
Please Help me bcz i am new in j2me development n having no experience

Ok ...
When you add records in you store, the J2ME implementation create an ID.
In the database, there is a list like that with ID <--> ]byte[ ]
You can get back a record with a this ID.
When you delete a record, it deletes the row. Lets say you have stored 3 records and that the ID are 1, 2, 3 ... if you delete the second one, then you have still in the database IDs 1 and 3.
That's why you have this exception : you are iterating with an ID 1, 2, 3, 4, 5 ... if one is delete there is no reorganization. (If you add an other record, it could be stored with ID 2).
To read all the records, you should get a list of existing IDs. Take a look at the API. Here is a piece of code, that you work but I have not tested :
RecordStore rs;
RecordEnumeration re = rs.enumerateRecords(null, null, false);
while (re.hasNextElement()) {
String str = new String(re.nextRecord());
System.out.println("Record: " + str);
} Hope it will help you.

Record set size in Gantt Chart

Hi all,
I am developing an application that has a Gantt Chart.
The tree drawn is a 2 level tree. I have two VOs.
The second VO (Child) has more than 20 rows. I want to show only 10 child at once.
Record set size attribute is the one that is used to restrict the size of the number of nodes displayed. Just like in HGRID.
But when the graph is rendered the values that I give are being ignored and the entire graph is rendered.
Any pointers or suggestions on this will be really helpful.
Regards,
Santhosh.

Hi Santosh,
As Anand suggested to add the "rownum <= 10" condition to limit the record set.
But this condition should be set in View Link SQL(Query where clause).
I hope this will work.
Thanks

Need advice: About record store

Hi,
I am developing an application which will first display a list of options to users (multiple choice i.e. with check boxes). The list of options could be anything, such as movie titles, etc.
The application will need to allow users to select their options by
checking the check box, and save the selected ones in record store.
My problem is, the next time when users launch the application, how
should it read in the records from record store, such that options
previously selected by them are "checked"? For instance, a user selected "Stardust" and exit the application. Then when he re-launches the application, he will see "Stardust" as checked.
I was thinking of using a loop, which will read in each record, and compare with the list; then check those which are identical. But I reckon this is rather inefficient? How shall I solve the problem?
Thanks in advance :)

Hmm... maybe I misunderstood your application. Where do you load the list, I thought it was from the RecordStore.
If you save only the selected items in rms, you've already done all you need to do.
Hey, by "control character" I didn't mean any special character. If I had to save all items and their selection status, I would probably prepend "Y" or "N" for the selection status and when loading, read the first character for status and the rest of the String for the name.
There may be a more efficient way to so this but I don't know of any. Keep checking back, some professional developer may offer advice.
Cheers, db

6230i 'record store full' when it isn't

When I download emails I get 'record store full' message. I have deleted all messages and all pitures. When I go to 'e-mail storage' it shows me that my inbox has zero messages, but it says that my inbox is 73% full! All other folders are empty. I have removed the card, sim, battery etc and restarted - no difference. Is this a hardware problem?
PS This used to work fine till yesterday - I always use my phone to download emails.

I have now solved the problem which suddenly apeared a few weeks ago. I backed up the entire phone using PC-suite having first saved all my contacts on the SIM card. (I don't trust the contacts management in PC-suite.)
I then had the phone software upgraded by my local dealer. I now have: nokia 6230i V 03.88 vs before V 03.70, 28 jul 06 RM-72, GSM P1.1
I then restored from the backup and got most of it back. Some minor problem with display etc settings. I also lost the email settings but I could download from my mail provider and it now works. The key seems to be that my inbox setting which before shoved 0 messages but 31% utilisation now is back to 0%.
Cheers JATO

Implementing a record store in a J2SE environment.

Hi,
I am new to J2ME, I am basically learning it as I go. What i am trying to do is convert a J2ME application so that it can run in a J2SE environment. I am intending on running several instances of this application in a desktop environment so I can perform scalability testing.
The trouble I am having is finding a way to implement the record store that is usually implement by the different classes that are included in the "import javax.microedition.rms.*" in the desktop environment.
If anybody has any suggestions as to how this could be implemented. please get back to me.
Thanks,
Darryl Smith

Hi,
I did kind of find a solution to this issue. I came across some code online that basically convert the j2me record store class into a j2se record store.
Take a look at the code here: http://www.mrl.nott.ac.uk/~cmg/EQUIP2/
I did however have to do a fair bit of tweaking to get it to do what i wanted but by looking at this code i got an idea of what i needed to do.
Hope this helps.

How to optimize recorded video size?

Hello, I made a Flash app to broadcast live cam to FMS server. After 2 hours of live stream the recorded video size is about 550 MGB (4 hours=1 GB). Is that normal or I still can optimize the video size?
This my camera setting:
camera.setMode(540, 380, 30);
camera.setQuality(0, 85);
camera.setKeyFrameInterval(30);

How to parse a record (from record store) to String?

Hi,
I have a record store which stores movie titles specified by users (from multiple-selection list). I tried to access the records using nextRecord() from RecordEnumeration. This would return a byte array.
How shall I parse the byte array to a String? I tried ByteArrayInputStream toString() method; I tried creating a new String with the byte as parameter. But it simply does not produce the original String. Sometimes it gives me something like a hex. string. Can anyone point out what has gone wrong?
Thanks.

lily2007 wrote:
toString() returns this: "java.io.ByteArrayInputStream@1cb37664"
What does it mean?That means that toString() is not overridden and does not return the content of the stream as a bytearray (ByteArrayOutputStream however does do this).
I tried the new String(byte) method and got back the original String but with some whitespace in front.Let me guess: you write the string using writeUTF()?

Record fetch size property hint

Hi all,
I'm using Oracle Forms Builder 10g and Oracle DB 11g. I have a LoV which selects about 150k rows. In fact in the DB the select * from <table> returns first 50 rows for about a second. My question is: What value to set for Record fetch size property to receive the first records faster because now it is loading about 20-30 seconds/which is unacceptable for me :) /. I checked docs for this property and if i increase it i suppose it will display rows faster?
Thanks in advance,
Bahchevanov.

The records are composed of two columns, a code (5 characters) and a description (average size 25 characters). The average size of the record is then approx. 30 characters. From the documentation available in Forms:
    Also, the way in which the actual value is computed when a value of 0 is
    specified has changed. The actual value in this case is now
    0.5 M / total_record_size (i.e. sum_of_column_sizes, not max_column_size),
    but no more than 100 and no less than 20. The coefficients (0.5 M, 100, and
    20) can be changed by setting these environment variables:
    FORMS_COMPUTED_RGFS_DIVIDEND, FORMS_MAX_COMPUTED_RGFS,
    and FORMS_MIN_COMPUTED_RGFS.I believe that we are running with the default. Is this OK for this data set? Do we need to set the environmental variables listed above?
Thanks,
Thomas
