Number of data block problem

number of data block
is there any limit for the number of datablocks in a form?
i have a form that has 8 blocks and all of them are none base,
some times when i use this form it suddenly closed and a special file (ifrun60_dump file)
is created.i donot know the reson and i cannot solve the problem
if you have any idea about this ,plz help me?
thanks in advance.
regards ,
shoja.

Restriction on the number of objects is documented in the Help topic "Limits" - There is no practical limit to the number of blocks in a form. Certainly 8 is a timy number compared with mosdt forms.
Contact support and supply them with the dump file, that should help to identify the issue you have.

How to reduce the number of data blocks used by table

Hi,
I was trying to reduce the space usage of a particular table of my apex application which stores blob content and therefore deleted many records from it.
However, the data block usage remained the same as before.
I have tried to 'analyze' the table and validate the structure,but am unable to overcome this problem.
Could someone throw some light on what needs to be to reduce the number of data blocks used by this table?
Best Regards,
Priya Jetley

Priya:
It is likely that the BLOB content defined in your table is being stored 'Out-of-Line'. This means that the LOB columns are stored in segments of their own. These then are the segments that may need shrinking.

File Sender / Separating a variable number of data blocks

Hi all,
I have a problem regarding the content conversion in a file sender adapter.
The source data has a fixed length of 10 chars, but is contained in one big line without any newlines or other sepators.
Example source data:
0123456789012345678901234567890123456789
The number of occurences can vary; that is the next file might contain more or less data blocks of 10 chars each.
Another example:
01234567890123456789
Is it possible to create a content conversion that handles this kind of data? We have already tried several configurations (for example using "fieldFixedLengths = 10") but didn't succeed. In most cases only the first data block is read an the rest is ignored. Therefore it seems to me that the adapter requires a newline in order to recognise data blocks.
The target xml structure should look like:
<Structure>
<Line>0123456789</Line>
<Line>0123456789</Line>
</Structure>
Do you have some hints on this one?
Thanks and regards,
lars

Hi Satish,
hello Ravi,
thanks for your replies.
If I understand it right, you would need two message mappings in order for this solution to work, resulting in the following steps:
- Read File into one big record using content conversion.
- Perform the first message mapping, splitting the content using the UDF.
- Perform the second message mapping, containing the "business-mapping".
Is this correct or is there a way to achive this in one single message mapping?
Thx,
lars

How to count number of items present in a data block

hi all,
how to count how many items present in a particular data block in oracle forms 10g.
whether it is a text_item or display_item or list_item etc is there any method to do this.
please reply....

hi all,
i have written this when-button pressed but the problem is how to get the next item name in the block
DECLARE
     V_COUNT NUMBER:=0;
     V_FIRSTITEM VARCHAR2(100):='';
BEGIN
     GO_BLOCK('BLOCK_ITEMCOUNT');
     V_FIRSTITEM := GET_BLOCK_PROPERTY('BLOCK_ITEMCOUNT', FIRST_ITEM);
     LOOP

Problem In Tabular Data Block

Hi,
I have to two blocks on a form (1) CONTROL----------------------------------------->CONTROL BLOCK
(2) DETAIL-------------------------------------------->DATA BLOCK
DETAIL BLOCK has four items referencing DETAIL TABLE COLUMNS namely ROWNUMBER, ITEMNAME, QTY, PRICE.
In BLOCK(1) I have three text items to get input from user, and a push button . In this block(1) user inputs ITEMNAME,QTY & PRICE and presses push button.
In WHEN-BUTTON-PRESS trigger I wrote below mentioned code
BEGIN
go_block('detail');
first_record;
for a in 1..:control.QTY loop
create_record;
:global.rownumber:=:global.rownumber+1; // this :GLOBAL.rownumber variable, I declared & initialized with zero, in WHEN-NEW-FORM-INSTANCE trigger.
:detail.rownumber :=:global.rownumber;
:detail.itemname :=:control.itemname;
:detail.qty :=1;
:detail.price :=:control.price;
end loop;
END;
If usesr enters QTY 4,,,,, four rows are being created in detail block as four records , if user enters QTY 3, three rows are being created, and so on as per number entered in QTY text item........THE PROBLEM IS THAT, ROWS(RECORDS) ARE CREATING BUT FIRST ROW IN DETAIL BLOCK REMAINS EMPTY AND IT STARTS CREATING RECORDS FROM 2ND ROW.
An help please.
Regards,

Hello,
Well, if you think that the code you wrote with global variable its working for you then for the problem you mentioned the below code should work.
BEGIN
go_block('detail');
first_record;
clear_block;
for a in 1..:control.QTY loop
:global.rownumber:=:global.rownumber+1;
:detail.rownumber :=:global.rownumber;
-- :detail.rownumber :=:SYSTEM.TRIGGER_RECORD; -- this line should work also. So, no need for global variable
:detail.itemname :=:control.itemname;
:detail.qty :=1;
:detail.price :=:control.price;
create_record;
end loop;
END;-Ammad

Counting number of records in a data block

hi folks,
Simple question for you guys: How can I count number of records in a data block.
In other words, say I have 10 detail records listed on a data block (one of my columns is a non-database item for entering a number). Now I just want to do somethin like:
Select count(*) From <data_block> into lnRecCount
Where <non-database column> <> 0 ;
Can I do this in a button trigger? I can't get it to work?
Thanks,
bob

You should make a routine that go through records of the block and count the records that agree with your condition.

Problem updating data block based on a view

Hi,
I have a data block that is based on a fairly complex view, which I want to make update-able. The default Forms behavior, of course, is to not allow this.
In an attempt to get around this, I defined an 'ON-LOCK' trigger, where I specified a single statement 'LOCK_RECORD;'. I also defined an ON-UPDATE trigger that will later call some stored PL/SQL procedures to effect the actual update (using INSTEAD-OF triggers and such). For now, I just display a message saying 'updation not currently supported'.
However, a problem occurs when I make a change to an item in the data block, don't attempt to save it, yet try to navigate to the next record. The form simply hangs and the only thing I can do is kill the process.
I'm deploying this form as within Oracle Apps 11i. I suspect this has something to do with the lock record but don't know how to get around this.
Does any one have any suggestions?
Thanks,
Niranjan Ramakrishnan

Your lock will be removed whenever the forms does a commit or rollback. In 'normal' forms processing the on-update trigger will fire as part of the commit form processing, which also includes a database commit which will remove any locks that have been taken out. Should the user clear the form a database rollback will be performed which will also remove any locks. You should not need to do any explicit removal of locks yourself.
I would not recommend not having any kind of lock processing, as Sudha says, as this could easily lead to changes to record's being lost. As long as the locking of table(s) is always done in the same order deadlocking should not occur.
You may make want to make the locking process a SELECT ... FOR UPDATE NOWAIT so if the record is already locked the user is informed and can try again later, rather than an unknown wait until the record becomes available.

Updatable View as data block source - can't get to work

I have created a simple form with one data block based on an updatable view, but it doesn't work properly after the form executes a query.
I can use DML on this view using SQL*Plus and it works as it should.
DML works in the form too, but only until I execute a query, after that I get the "FRM-40602: cannot insert into or update a view" error each time I try an insert, update, or delete.
This is repeated for each runtime of the form. I have set the "query only" property to yes for the non-DMLable item from the view so that isn't part of the problem. This is an example out of "Developer Advance Forms and Reports (page 112) - Oracle Press" so it should work. There is nothing else (code, triggers, etc...) in this module besides the one data block.
Any ideas would be appreciated.
Thanks. Bill Brosnan.

I have had the same issue and had to go through Oracle Support to get it working.
First of all make sure that you have a recent patch installed (patch 9 as being the latest one available).
Second, set in the data block the property key mode to updatable and the property primary key to yes for one item of the data block. (this is bug 1561423)
Make sure that you only modify those columns that are updateable.
Quite a large number of bugs have been reported on the concept of updatable views and the installation of a recent patch will most definitely get you working again.
This functionality does work !
Goodluck,

Perhaps, you block have a non database items but they is declared as database.

Upload data from microsoft access to oracle form(in data block)

Hi all,
Any one can help me, how we can upload data from access file to developer form(in data block).
as
we upload data from text file to developer form(in data block) using some packages.
Thank's in advance

Hi Zuhair,
If you give details of the problems you are still having then we should be able to get SQL*Developer to work.
However, if you don't want to use SQL*Developer then the following options are taken from note 393760.1 available in Metalink if you have access to that -
1. Use a gateway that supports the non-Oracle database or generic connectivity if a third party ODBC driver is available to do a -
'create Oracle_table as select from non_oracle_table@database_link'
for each table. You would then have to manually create all the other objects (views, indexes, stored procedurs etc) and permissions etc that existed in the non-Oracle database.
2. Use the SQL*Plus COPY command to copy data from the non-Oracle database to the
Oracle database using a gateway or generic connectivity. The syntax is as follows:
COPY FROM username/password@oracle_sid -
INSERT destination_oracle_table -
USING query;
The following example selects all rows from the EMP table in the non-Oracle database and
inserts them into the local Oracle EMP table:
COPY FROM SCOTT/TIGER@ora10 -
INSERT EMP -
USING SELECT * FROM SCOTT.EMP@gateway;
where "gateway" is the database link created for the gateway.
3. Load the non-Oracle data into flat files and use SQL*Loader to put the data into Oracle tables. Again manual
work is required for the other objects.
4. Contact the Oracle Product Technology Services (PTS) group for assistance. See the webpage -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
5. Use a third party migration tool. See -
http://www.oracle.com/technology/tech/migration/isv/third_party.html
6. Use JDBC to connect to the non-Oracle database and Java in the Oracle database. This method will work but it is not suppported by the JDBC team.
=========
The amount of work involved will depend on the number and size of Access tables that you want to migrate.

Mike

ORA-10561: block type 'TRANSACTION MANAGED DATA BLOCK', data object# 237

Hello,
I encountered ORA-10561 while I was recovering my DB.
Problem Background :-
I took a hotbakup of my DB running in Windows, I edited the Pfile and recreated the control file
I was able to succesfully mount the DB
The I gave the below command to apply the redologs and recover the DB
And the errors followed as mentioned.
The HOTBACKUP was copied and restored using a USB-PENdrive. I suspect that the datafiles and / or ARCHIVE LOGS would have had some format issues due to O/S {WINXP ---> RHEL5}
If this is the case ? then I would like to know how to convert the format of the files(Datafiles and or Redologs)
into acceptable format

You need to give much more information:
What version of Oracle? 10gR2 is not a version, 10.2.0.1 is a version.
What version of Windows, exactly? What version of linux?
ORA-600 means you need to talk to Oracle support. There is an ora-600 lookup tool, which basically searches the knowledge base (for ora-600[4502] in your case, which brings up a bunch of really, really, really old docs).
How exactly did you take the "hot backup?" There are a number of ways to do things with that name, some of which are just plain wrong.
How exactly did you get the backup from one machine to another? Which exact commands did you use to copy the files to the usb and from the usb? Did you do it more than once?
Why are you using the backup controlfile syntax? There are valid reasons, and invalid reasons to do that.
What exactly did you change in the pfile?
What does the alert log say about all this?

Scrollbar doesn`t scroll data to the end of Data Block

I have a strange problem. Datablock is a list with 15 rows and its got a scrollbar. When i scroll down to the last element it seems to work fine but when i select the last element and press the down arrow key i`m moving to the next element not listed before. Scrolling cuts off 10 last elements and to view them i must use the arrow keys. The same situation is when i`m at the end of list and want to move to the top, 10 first elements are hidden.
Is there any solution for this problem ?

Ok the problem was that the Data Block parameter Number Of Records Displayed was set to 25 and the real height of the list could show only 15 items.
Solution* for my problem is to set the Data Block parameter Number Of Records Displayed to number of rows that are visible (15).

Insert and update a data block which is based on view--urgent help required

Hi experts,
I created a view(A_VIEW) which is based on a union select. I have created a data block A_VIW_BLOCK which is based on this view. I need to insert/update one of the base tablesfor A_VIEW through this data block. I also need to be able to make a query through all the fields in the view.
The questions are:
1.Can it be done at all?
2. What properties need to be set?
3. If can't be done, what the best approach to achieve this?
Thanks in advance!!
