Form element id changed after upgrading from APEX 3.2.1 to 4.0.2

Hi,
We are in the process of testing an upgrade of our APEX 3.2.1 app to 4.0.2. The production database was exported, imported as a new database, and then upgraded to 4.0.2. I've noticed that on pages where we have coded our own PL/SQL process in place of the built-in MRU, the form element id (referenced using g_fxx) has changed. For example, in our existing production system, the id for the first row of data is f06_0001, but when we look at the same page in APEX 4.0 environment, the element id has changed to f08_0001. Is this a known issue when performing an upgrade? Has anyone else experienced this?

Hi,
I have seen this problem.
I assume that Apex 4 do not give fxx name to items anymore in order where columns are in query.
This is one of reasons why we have not been yet able to upgrade.
And it seems this same problem exists in Apex 4.1 on apex.oracle.com

Jari

Report Layout Changed After Upgrade from 4.6C to ECC6

Dear Gurus,
I do functional test of every process in ECC6 after upgrade from 4.6C. I found all report layout changed without variant (it's happen to all Query/SQ01 reports ). So I've to assign manually the fields for the reports, and create a default variant then.
Why it happen ? Is there configuration or setting missed or this is standard while we do upgrade ?
Thx in advance.

We do re arrange for all ALV report ...

The optimizer changed after upgrade from 8i to 10g

I have upgraded my Oracle database from 8i (8.1.7.3) to 10g (10.2.0.3). After upgraded, there's some SQLs are with performance issue that the response time is very slow. The SQL can run very fast (around 1 seconde) in the pre-upgrade environment. Also, after generating the execution plan, there's different from the original enivronment (8i) which the query using some full table scan instead of index scan originally used in 8i.
The optimizer_mode of 8i is RULE and it's CHOOSE when upgraded.
My questions are:
1. Do I have any init.ora parameters setting in 10g environment which differ from 8i?
2. What method of analyzing tables is appropriate to use in 10g? Will this affect the performance like my case?
Thanks,
Wai

The synth pad sound Warm Pad has changed after upgrading from Logic Express 7 to Logic Studio

Hello!
I have composed a lot of songs over the years using Logic Express 7, and my favourite synth pad sound there was a sound called Warm Pad (from the EXS24 Sampler).
A half a year ago I upgraded to Logic Studio, mainly because I needed WaveBurner. Happily, all my songs sounded exactly the same after the upgrade, except from 1 sound: The synth pad sound Warm Pad. It still got the same name and location, but the sound was replaced with a very sharp and much more distinct sound (not warm at all, in my ears at least).
I have tried to replace it with different synth pad sounds from the EXS24 Sampler, and the one I find to come most close to the old Warm Pad from Logic Express, is a synth pad sound called Pad 1. Still, I don’t think it sound exactly the same.
So, in order to finish all my songs and make an album, I ask you for help:
1. Do you know how I can get EXACTLY the same sound as the old Warm Pad Logic Express, with my new Logic Studio?
2. Have you experienced the same with sounds, after upgrading from one Logic version to a newer one? And what have you done to find back to the old sounds?
I will be VERY thankful for help, because I am not a genius in the mysterious (but yet exiting) world of synthesizer synthesis.
Best regards,

I have the boxed version of logic studio.
When you install, if you pick the "ad hoc" installation you can add the logic7 patches to your existing patches.
I think running installation again you should be able to install just that.

Menu Position Changed after upgrade from Forms 10 to 11

Hi,
I have upgraded an application from Forms 10 to 11g. Everything is ok apart from the position of the menus.
In Forms 10 the menus are attached to the window they relate to e.g. a pop up form has the menu (normally default&smartbar) displaying at the top of the pop up window but on the 11g version the same menu is displayed at the top of the screen looking like it is attached to the MDI window.
Is there any way of restoring the original functionality in 11g please.
Thanks,
Jim.

It sounds like this has nothing to do with the version, but rather your configuration. To attach the menu to the form window, set useSDI=yes. To attach it to the MDI window, set useSDI=no or leave it unset. This parameter can be set in formsweb.cfg or in the url used to run the form. For example:
http://server/forms/frmservlet?form=myForm&otherparams=useSDI=yes
Note that useSDI is a Forms runtime parameter and not an applet parameter, so it is set through "otherparams".

Parameter Form look & Fee changed after upgrading to the Oracle Reports 11g

Hi All,
We are using Oracle Database 11g, with Oracle Forms and Reports 11g.
We are in the process of migration our customized application from Oracle Forms 6i to Oracle Forms 11g, during migration we have faced a problem regarding the look and feel of reports parameter form,
We have almost 700 reports and 300 out of them are calling with report parameter form = yes,
When we call any report that is using Report Parameter Form, we have found that the look and feel completely changed, although it is acceptable for us as we have standardized the parameter form, with default layout, but the only problem is that, we are unable to fixed the length of any field having LOV, i.e. we have a field, that is showing Department Name, having Select DeptId, DeptName from Departments order by 1 and we have set the Hide First Column, when we call the report the length of this field systematically increased according to the biggest Department Name (Department Name having the highest number for characters), we want to fix the length of every parameter to a certain size,
Would gurus please advice?
Thanks,
Hassan

Accessing wwv_flow_files changed after upgrading from 2.0 to 2.2

We have recently moved to 2.2 After the move uploading files, under some circumstances, failed.
Further investigation found that the upload was working fine, accessing wwv_flow_files table had changed in some way.
From the SQL Workshop we could see the files which had been uploaded. From SQL*Plus we couldn't see the same files.
I have read Re: Lost permissions on WWV_FLOW_FILE_OBJECTS$ and see at the end it says that access to wwv_flow_files is not supported from SQL*Plus. That's fine.
The problem we have is that the same limit seems to apply to functions called from within an APEX application. We have a function that at one point issues the following SQL -
SELECT blob_content
INTO l_blob
FROM wwv_flow_files
WHERE name = p_file_name;
(The function goes on to extract rows from the uploaded file to be uploaded into a table).
This function was not able to find the row which we knew was in the table.
Drilling down wwv_flow_files is a view of wwv_flow_file_objects$ with the following condition 'where security_group_id = wwv_flow.get_sgid'
By changing the original SQL to
SELECT blob_content
INTO l_blob
FROM WWV_FLOW_FILE_OBJECTS$
WHERE name = p_file_name
AND created_by = 'HTMLDB_PUBLIC_USER';
we get what we want.
My question is .. as the function is called from with an APEX application, why is the where clause preventing it from accessing the data we need.

Thanks for the details, it's making more sense to me.
The function extracts the rows from the uploaded file and displays them in a textarea.When you say "and displays them in a textarea" it sounds like something that happens during page rendering. But I think maybe your page selects the rows in an after-submit process and puts some content into a textarea item for display during the next page "show". Tell me if I'm on the right track. In 2.2, there's a bug that prevents queries from seeing the just-uploaded "files" or rows until after computations have fired. You need to move any code that selects those rows to a process "after computations and validations" (you could run it as a validation if you really needed to). Let me know if you think this explains what you're seeing. This is fixed, by the way, in 3.0.
The created_by = 'HTMLDB_PUBLIC_USER' clause is required as the >>WWV_FLOW_FILE_OBJECTS$ table also contains objects created by other users, for >>example ADMIN (eg APP imports etc)But your predicate specifies "where name=" and name has a unique constraint so you'll get the row you want without specifying created_by.

Applications not working after upgrade from apex 3.2 to apex 4

hi,
we've created an application with apex 3.2 which works fine.
today we upgraded apex 3.2 to apex 4. after the upgrade the application doesn't work anymore.
we recognized the following things:
- interactive reports don't work anymore
- tabs don't work anymore
- buttons don't work anymore
what do we have to do, to get our apex 3.2 application to work with apex 4?
regards,
matthias

I've seen similar problems to my applications. I've found a problem with the derived columns or link columns in reports. The only solution I founded is to delete the columns and then make them again. Now are working. No problem founded specifically for the interactive reports. If there is an automated solution for the derived columns or link columns it will be appreciated ;-).

After upgrading from acrobat 9.5 to XI pro my users have complained on slow typing when filling in form that were created in version 9.5?

After upgrading from acrobat 9.5 to XI pro my users have complained on slow typing when filling in form that were created in version 9.5?
The issue is they type but there is 2 second delay when it appears in the field.
Windows 7 64bit

I see, I misread your reference to Reader 11 to mean you were using Acrobat 11, but it looks like it worked out anyway.
The base-14 fonts are special in PDF because they are guaranteed to be available even if they are not embedded. If you select a non-base-14 font for use with a form field, the entire font usually gets embedded, since each glyph it contains has to be available for use with the field. This can take up a lot of space if you do this a lot, and the space isn't reduced if you change back to a base-14 font later because the internal reference to it is not removed. This is caused by the bug I mentioned.
In your case, however, the entire font doesn't get embedded because fonts like it (e.g., large asian fonts with a lot of glyphs, Arial Unicode) would take up too much space if fully embedded. If it did, a 100KB PDF could bloat to 20MB with that one change. Instead, users are expected to have such fonts installed on their system, which is why you were prompted to install the font pack. This despite the fact that the font was not actually used by anything in your document, it was simply the orphaned reference to it that triggered this. This should get fixed in Acrobat eventually so this type of thing doesn't happen again.

What exactly happens ? Can you see the processes running in Task-manager?

How to change table defnition after upgrade from 9 to 10 ?

Is there a method to convert it all tables to new 10g style without re-create thousands tables then emp/imp one by one?
Thanks

What do you mean by "10g style"? Do you want tables to be using ASSM? If that's the case, that's a feature of tablespace itself. So it means that your tables need to be in those tablespace which are having Segment Space management auto set in them.I don't think that there is any automatic package which can do the same on the fly.
One way ,which may not be very less time consuming but still can help is to convert the segment space management using EM.But again,this does recreate teh tablespace so I don't think that this is any different from exp/imp.

Masked HTML tags in substitution strings after upgrade to Apex 2.2

Hello, 
 
in my application developed with htmldb 2.0 I had the following scenario which worked fine until upgrade to 2.2: 
 
Requirement: a multiline text should be displayed as entered on a html report page. 
My solution: 
- a onload page process of the form 
select replace(description,chr(10),' ') into :P1_DESCRIPTION from mytable where id = :P1_ID; 
- and a page template containing 
... 
<td>&P1_DESCRIPTION.</td> 
... 
 
This worked in HTML DB 2.0. 
 
My problem: After upgrade to Apex 2.2 the report doesn't display the carriage returns anymore. Instead of interpreted BR tags I get masked BR tags printed as text: 
 this is the first line this is the second line 
It's quite obvious that the substitution mechanism changed in Apex 2.2. Any ideas how to change my app ?

Take a look at this thread:
Computed Region TItles being Escaped in Apex 2.2
You may have to change the type of your P1_DESCRIPTION item.
