Hi All,

i have created DB level trigger,but it is not inserting in DB.
If any one is having the coding you can plss send me sir,
this is very urget
Thanks,

i have created DB level trigger,but it is not inserting in DB.It might help if you explain more about what you've done and what didn't work.
You can use :sequence.my_seq.nextval in the Initial Value property of an item to default it to a sequence value.

Hi all
i have six fields and when-validate-item trigger is working on block level, i want to display records in one field,i want when-validate-item trigger work on item level not on block level,any help will be greatly appreciated.
here is the code.
When-Validate-Item Trigger.
declare
     Str_Space VARCHAR2(20);
begin
Str_Space := ' ';
:ins1.ref := :ins1.branch || Str_Space || :ins1.class || Str_Space || :ins1.year || Str_Space || :ins1.serial || Str_Space || :ins1.cno || Str_Space || :ins1.edno;
end;

Francois Degrelle.
just look the following code.
DECLARE
     Str_Space VARCHAR2(20);
begin
     Str_Space := ' ';
:ins1.ref := :ins1.branch || Str_Space || :ins1.class || Str_Space || :ins1.year || Str_Space || :ins1.serial || Str_Space || :ins1.cno || Str_Space || :ins1.edno;
END;
by using the above code i am passing branch,class,year,serial,cno and edno to Ref column( 1 G01 2009 13112 00 01). and Str_space variable is creating space for each item.i want the above code work at item leavel instead of block level.Is it poassibl?

Change visual_attribute on current item at block level

Hello everybody.
Is there anyway to apply visual_attribute on current item at block level ? Explanation: i have block with a lot of items, so it's really hard to create many POST-TEXT-ITEM triggers on every item and apply visual_attribute on it...
Thx in advance.
Adnan

Hi,
You can set the visual attribute using the following as per your requirement:
This is for item instance
Set_Item_Instance_Property( 'Your item', CURRENT_RECORD, VISUAL_ATTRIBUTE,'Custom_attribute'); for item
Set_Item_Property( 'Your item', VISUAL_ATTRIBUTE,'Custom_attribute'); regards

Block level changes on linux when a datafile is reduced by resize

Hi All,
Does anyone know what happens at the block level on Linux when an oracle datafile has its size reduced. For instance, if I have a 6gb datafile with has had the extents written to but the current HWM is 2gb and i then reduce this datafile size from 6gb to 2gb. On the file system the file is resized to 2gb but what actually happens to the blocks on the OS? The reason I am asking is because I am running Linux on vmware and the vmware file is replicated at the block level. How much additional data would be replicated if I reduced the datafile with a resize. Would it replicate the 4gb difference, or is only the end of the datafile changing and if so are only a few blocks changing. Oracle seems to reduce the file size quickly so I am assuming it is not changing many blocks. Any ideas?
cheers,
Matt

Hi Matt,
Are your datafiles on ASM? Raw? Filesystem?
I have not tested it, but I suspect that Oracle simply re-writes the extent map, whether that's in ASM, on the raw device, or on the filesystem.

How can we disable Block Level Trigge using Form Personalization

Hi,
I want to disable block level trigger(WHEN-NEW-RECORD-INSTANCE) using forms personalization at responsibility level.
Can any one please give me the answer.
it's urgent
Thanks and Regards,
Dhana

No, Firefox is user choice rules over the "wants" of individual websites as far as disabling contextual menus and the keyboard commands.
Placing a transparent image over the image will keep the less technical user from saving the main image. If they do try to save it all they'll get is the transparent image overlay.

Form level Trigger Vs Block Level trigger

I have a form with single Database Block. I need to write a
transaction Trigger for this Block. I need to know r there any
advantages of writing the triggers at Form Level rather than at
Block Level.
Thanx in advance

Hello,
If you have to handle this stuff in more than one block, it seems more generic to put the code in a form-level trigger if you don't want to duplicate it several times.

Scrollbar on block level

Hello,
I'm trying to migrate a application from forms 4.5 to forms6i. If I want to run a form which has a scrollbar on the block level the runtime crashes down.
I could compile and generate the form without any errormessages.
It works if I set the scrollbar property on no. Does anybody know a solution for this problem?
Thanks,
Dirk

You can use a materialized view to ensure database integrity. Check for constraint violations in the MV when you commit the form.
need some help

Pre-insert block level, Seq.Nextval leaving gaps problem

Hi...form friends,
I used DB sequence in pre-insert block level trigger.
SELECT seq1.nextval INTO :abc.log_id FROM dual;
Everything works fine,except leaving gaps randomly .
It leaves around 10 no.s gaps in-between. And that happens randomly...
lets say I insert 5 records..then it will be 1,2,3,4,5.
Then it may jumps to 15,16,25 like...that....
I searched for this problem...but some say when form failure occurs, it leaves gap of CACHE no. specified....and some say its not possible to use DB seq. with forms perfectly ..!!!!
Anybody have any idea about this issue ???
Thanks....

Putting that functionality in a row level trigger will cause a mutating data exception.
Locking the table for update is not sufficient, you need to prevent other users inserting as well.
I've posted a method a few times before which uses dbms_lock and a table of serial numbers which is used in place of the oracle sequence. This provides maximum concurrency and allows for data to be rolled back, but there is obviously a payoff in terms of performance so it should only be used when absolutely necessary. There is a similar example in the link I posted above (which is a far more considered explanation than I've posted elsewhere!), along with some caveats about using gapless sequences and whether there is truly a need.

KEY-CLRFRM Trigger at Block Level

Hi
Version - Forms Builder (9.0.4.2.0)
What's the use of KEY-CLRFRM @ block level?
I have requirement where I need to clear all the blocks except one block in the form when press F8 (clear_form). Is this possible.

Hello,
You could create a form-level KEY-CLRBLK trigger, then test what block raised the trigger (:SYSTEM.TRIGGER_BLOCK) in a If ... Endif structure.

Block level tracing to a file

Hi all,
I would like to output the block level trace in a form to to a file(by default its console)...WHERE DO I SPECIFY THE PATH TO THE FILE? I have checked waveset.properties and SystemConfiguration files but found that we can only specify the trace of an entire workflow..
"Block trace to a file" is what i want..
Yash

From the FAQ on Sharespace
SUBJECT:
How to dynamically enable trace for a single workflow.
QUESTION:
If you've ever enabled workflow trace in the Waveset.properties file, you know that
it can generate a lot of output. Is it possible to just enable tracing for a single
workflow?
ANSWER:
There are three ways to turn on workflow trace:
- Waveset.properties file
- in the WFProcess definition
- with a workflow variable
To enable trace unconditionally for a particular process, you will need to edit the
XML of the TaskDefinition object.
Locate the <WFProcess> element and add this attribute:
trace='console'
to trace to the console or:
trace='workflowTrace.txt'
to trace to a file. You can have more control over when tracing happens by using a workflow variable. The engine will look for a top-level workflow variable named "trace" whose value may be set as shown above.
For example:
<Variable name='trace'>
<cond>
<eq>
<ref>accountId</ref>
<s>adminA</s>
</eq>
<s>workflowTrace.txt</s>
</cond>
</Variable>
This turns trace on only if the workflow is operating on a user named "adminA".
You could also set this in a form field if you want to control trace interactively.

Windows could not start block level backup engine service

Hello,
              Im
trying to perform system state backup for one of the server its unable to run. Last week we have performed the system state backup without any issue.
Operating System:2008
OS Version: R2 Small Business Server 2011 x64 Edition Build 7600
RAM-32 GB
Following event ID is reported in the logs;
Log Name:      Application
Source:        Microsoft-Windows-Backup
Date:          7/2/2013 2:25:35 PM
Event ID:      754
Task Category: None
Level:         Information
Keywords:
User:          SYSTEM
Computer:     ABC
The Block Level Backup Engine service has stopped.
When we try to restart the Block Level Backup Engine service we get error as “Windows could not start the Block Level Backup Engine Service on Local Computer.
Error 0x800700b7: Cannot create a file when that file already exists.”
I have already restarted Virtual disk and Volume shadow copy service, but no luck.
Any help in resolving this issue will be much appreciated.
Thank you.
Keshava

All,
Here is the solution which worked for me ;
Services.msc >properties page of Block Level Backup Service Engine
Changed to Log On tab
Instead of Log On as Local System Account changed to Log On as
[email protected] (select the account with admin creds), entered the password of admin and closed the properties page.
Now restart the Block Level Backup Service Engine and re-run the job, backup completes without any issue.
Thank you
Keshava

File/Block level backup for AWS Amazon EC2 instances?

Block level backups would just be the snapshots. Mostly you don't want to do full backups of cloud instances, it's ideologically incorrect. File level backups are different. Find the things that need to be backed up, like configuration files and database data and back that up. You can use something like Unitrends or StorageCraft. Or you can manage this yourself. Script MySQL to back itself up locally, transfer the backups off with RSYNC or similar tools.

We have a few EC2 instances running on AWS and using snapshots going to a different region as a DR solution, but we don't have a backup solution. I'd like to setup a backup in AWS to backup other EC2 instances. I need the ability to restore MS-SQL and Files to these EC2 instances.

Block level filters on measure object

Hi,
Wanted to know a way to suppress rows in a crosstab with all zero's
I.e. if the measure value for a complere row is zero , it should not be shown.
Or indirectly, how do I apply block level filter on a measure object in webi?
I am using block level filters on dimension objects but could not find how to do this on measure object to achive what I wanted.

Hey David Thangaraj,
Filtering Measure objects is not possible.
Use Alerters:
Before creating Aleters, do sort on your Measure column.(ASC/DSC)
1. Name Alerter
2. Condition: Measure = 0 then <Format>
3. Make Fore and Background same <White & White>
4. Remove Borders
5. Save (OK).
Now apply this Alerter condition on toal row, means on all columns/objects there in Report/table/block.
OR
Select the Whole Block:
Go to Properties:
Uncheck : Show when empty
and Show measures with empty values & Dimensions check boxes also. (Am not exactly remembered text)
Hope this way you can do that.
Gracias...!!
