What must be changed before and after upgrade to 10g?

Hi,
We need to uprade databases(8i/9i) to 10gR2.
How do the uprades affect the current applications?
What need to changed in applications?
Notes: The applications may be developed by VB,Java,.net,oracle Form...
Thanks,

In general the answer on what needs to be changed depends on the version being upgraded to and the tools and manner in which the application are coded.
Most everything will upgrade cleanly to 10g but what you need to do is create a test system, upgrade it to 10g, and point the applications at it and test, test, and test.
One thing to watch for is current cleint-server type applications that may be using an old Oracle client that needs updating. Also you might want to check on the version of ODBC drivers being used.
If you have support you might try some target metalink searches on specific products like Forms using key terms like Upgrade, 10g, etc...

Test scripts for queries before and after upgrade (bi7.0)

HI,
i need to create a documnet for testing the over all functionality of the queries and wad before upgradation and after upgradation(bi 7.0) like structure, rkf , ckf variables, etc , please guide me and send me if any sample template available on this scenario
Thanks in advance

You can spool (or put in a database table) in your 10G database the sql statements and their performance metadata (this should be done when the system is really used). After the upgrade you can do the same select as used to spool. the statements in the 10G database and compare them (again in a really used system). A sql statement to use could be:
select inst_id, sql_id, hash_value, executions
,(cpu_time/executions)/1000000 cpu_time
,(elapsed_time/executions)/1000000 elapsed_time
,(disk_reads/executions) disk_reads
,(buffer_gets/executions) buffer_gets
,(rows_processed/executions) rows_processed
from gv$sqlarea
where executions>0
order by inst_id, sql_id, hash_value

To do's before and after upgrade

On another post, I noted that I cleared my home screens prior to upgrading as was suggested on a droid life site. The upgrade notification will be obvious and you get to choose between install now, or wait, or get more information. I just held off the install and deleted all my icons. Then went to settings, about phone, and system updates, and ran the update. It took about 2 minutes to download and a few to reboot. After that I reset my home screens which you will want to do anyway since you will have 5 of them. I had to reset my ring tones which was fine as they were due for a change. If you use swype beta you will need to unintall it and its installer and get a new installer emailed to you from swype.com. That was about it. Then just spending time figuring things out.

I see where in the other thread you have a link posted in there. That link is for manually doing the update.
I haven't had any problems with the update and I didn't do all that stuff that you said you did. So IDK.

What are Before and After Images ?

Hello Masters,
Best wishes to all.
For the past one week I've learnt many concepts from SDN, got all my doubts clarified.
On the same roll, I have one more question
What are Before and After Images ?
Where do we come across these terms ?
Could you please explain with an example ?
I always thank my replies in points
Thanks in advance...

Hai....
Before and After Images:
This Term is Used in the " Change Log "....
Change Log is one of the Table used in ODS....
That means the Changes in Running Request in ODS....
Example:
If you Enter the Request to " New Table" after activation the Request will be Deleted From the Table, You can see that in Change log......

Split view for before and after changes?

One feature I used to use a lot on Lightroom as where it would show a split view showing the image before and after changes (adjustments). I cannot find how to do this in Aperture - is it possible, what is this feature called?
(and before any smart person tells me to look in help, I'm tired of responses like that. I've looked and didn't find, and that's why I'm asking here. I've tried Compare, and Before and After Changes etc.)

Unfortunately, no, there is no ability to do the split view like Lightroom has. It's a nice feature.
The closest you can do is to flip back and forth between two versions. Because when you view the master in aperture it shows the original file without crops and straightening, I suggest that once you crop and straighten, you then create a new version and work on that (this is as close as you can get to LR's "snapshot" functionality). You can then flip back and forth between the two versions to see the changes... but you can't see them side by side with a split.

I'm unable to update my apps or download new apps to my Iphone. When I try I get a message "An unknown error has occurred". It was happening before and after the last OS upgrade. I've done a hard reboot with no effect. Any suggestions???

Have either of you had any luck with this issue. It began happening to me today when I was trying to purchase music on iTunes. I have purchased music and games in the past and have had no problem. Any help would be appreciated.

Changing transition changes time of clip before and after???

When I add or change the transition time, after it renders, the time of the clip before and after the transition automatically changes. I've done it several times and it shortens the time of the clips before and after the transition. Why does it do tht? Its driving me nuts. I keep changing back the time on the clip but when it re-renders it goes back to the time after I changed the time on the transition. Help please thanks lots

Hi Iluvvartan - that is normal. Transitions use portions of the clips adjacent to them. Cross dissolves for example take a portion from each, and the total length of the project is reduced. The Overlap transition only affects the length of one of the adjacent clips, and the total length of the project remains unchanged.

My camera is producing blurry photos before and after ios5. What to do?

My camera is producing blurry photos before and after ios5. What to do?

Jp0man-
There are several reasons a photo might be blurry. It might be out-of-focus, the iPad or subject might have been moving when the photo was taken, or the blur might actually be noise resulting from not having enough light.
Try taking a photo of a fixed object 3 or 4 feet away with a lot of light, with the iPad propped against something solid. If you still get a blurry image, you may have a defective iPad and should contact Apple about it. If you can demonstrate the problem to an Apple Store Genius, you may get a new iPad on the spot.

Bug: Before and After Margins Layout with section starting in right page

Hi,
I am using the Spanish version of Pages 09. I have observed that when I start a new section, I have no problems setting the layout margins (right, left, before, after) of this section.
But if a set that the new section must start in a right page, then the "before" and "after" margins of the layout doesn't work.
Is this the same in English versions of Pages?
Regards,

I see what you are saying.
The problem is Pages seems to have a memory of how you arrived at that layout.
When I construct the pages, it is correct.
I am trying to find out what is interacting in your layout to cause this to happen. It is like there is a hidden inaccessible layout break on the blank inserted page.
I have been tearing my hair out trying to work out what triggers it off. As I experimented with the combinations of settings in Facing pages, Section layouts and which page it starts on, it erratically switches back and forth.
This is why I gave up on Pages years ago as a serious layout tool. It has too many of these raw, poorly thought out interactions. I use a lot of different applications and none of them, that I can think of, have so many of these mind twisting raw oddities. Odd for a supposed user friendly application.
All the rest are pretty literal, you apply the settings and end up with a logical result of those settings. If the result is not what you wanted it is a matter of tracking what is interacting with what and straightening it out. Pages has the annoying "design" of inexplicably greying out functions for no stated reason, that prevents correction. Or hiding the access to the tools to those settings. You can only get to some of them if you have explicitly done something to make them possible. The rules as to what that "something" is, are not apparent nor in most cases explained in the User Guide or the User Interface.
There may be a "reason" why the function is greyed out but it is not revealed to the user without an enormous amount of detective work and as in this case my sleuthing abilities are failing me completely. I might try it again tomorrow after a rest (it is very late here). Either way it is a huge time waster.
This is fundamentally bad User Interface design and what I have railed against since Apple changed shifts, bringing in the OSX programmers who never really got the polished UI of the original Mac OS and have been cooking with Fanta* ever since.

* This is an anecdote originally told by Peter Russell-Clarke, a well known and creative Australian chef back in the 70's. He was berated in the street by a woman who told him that his recipe for +Duck à l'orange+ was "disgusting". When he cross examined her, he found she didn't eat fresh fruit so had made the orange sauce with Fanta.
I use this to try and get the message over to clients when they insist on "substituting" material because "what's the difference". The trouble with people who can't tell the difference is that they rarely ever do, no matter how carefully it is demonstrated to them.

Repairing permissions before and after updating software

What is the reason to repair permissions before and after updating software? This may sound like a stupid question to many of you, but I am new to computers and I am trying to learn how and why of some of the things of my PowerBook. I installed some updates without repairing permissions. Did I install some software updates the wrong way? Thank you.

This is a topic which will draw as many emphatic for and against responses as overnight shut down or not, defrag or not, optimise or not, and so on.
I agree with Neil. I believe that OS X has progressed sufficiently that repair permissions has become redundant and so I do not do it on any regular basis.
Some folk may refer you to an Apple Support Article 303602. That Article in its 4 May 2006 version, titled "Top 10 Tips to Keep Your Mac in Top Form" suggested Repair Permissions should be done "after upgrading or installing new software". The Article was however revised on 15 May 2006 to be titled "Top Tips to Keep Your Mac in Top Form" and the item on Repair Permissions [along with two other recommended maintenance tips] was removed. It is my view that the conclusion to be drawn here is that Apple no longer considers Repair Permissions to be a required maintenance procedure.
Many users have adopted a "Repair Permissions" mantra for a cure-all over several years. I dropped it sometime in 10.3.
But, to each his own.

Before and After insert or update rowcount

Hi
I have several extract objects procs which are calling various build objects procs which in turn are inserting or updating the tables...now when i run these objects sometimes i get no errors and everything seems to be running perfectly but the tables do not get updated ? now what i am trying to achieve here is get some kind of summary where i can see the before and after rowcount..for that i have created a table of every extract object proc and another table with the coressponding tables being updated by tht proc...can anyone pls tell me how should i look into these procs and how do i get the rowcount for a particular table before and after the procedure was run ?
Thanks a lot in advance

Hi,
On which version of RDBMS are you working , because if you're on 10g then just enable auditing or even FGA on the tables were you want to see the changes,
Then query the DBA-AUDIT (not sure of the name anymore) view.
If not then create a audit package yourself.
something like
create or replace package pck$audit as
procedure prc$check_tablecount(p_tablename IN VARCHAR2, p_status IN VARCHAR2);
end;
create or replace package body pck$audit as
procedure prc$check_tablecount(p_tablename IN VARCHAR2,p_status IN VARCHAR2) IS
sqlstr VARCHAR2(100);
v_count NUMBER;
begin
sqlstr := 'SELECT COUNT(*) FROM '||p_tablename;
EXECUTE IMMEDIATE sqlstr into v_count; --could by 'using v_count' check syntax for this
INSERT INTO audit_table(table_name,total_count,status,time_stamp)
VALUES(p_tablename,v_count,p_status,SYSTIMESTAMP);
COMMIT;
end;
end;
you can elaborate on this creating additional procedure checking differences in total_count on same table at same time.
Now call this procedure before starting your insert-delete- on your table make sure you put the parameters correct eg p_status => 'begin procedure'
and call it again after your commit in your procedure.
Hope this helps you out

Proble with Before and After in camera raw

The problem that I am having is the before and after in Camera Raw. When I press the P key for before and after; CR display the before and after to whole changes that I made and not just to one section. Let say, I am in the Detail section and Just want to see what changes I made in the Detail section only. I used to press the P key, but now I am seeing all the changes that I made to my file. I am using Adobe Photoshop CC and all my software is updated. I appreciatre a fix to this problem with many thanks

Alternatevely you can take advantage of the new function recently introduced in CC. Press "Q" , this will split the monitor in two, (either vertically or horizontally) and each time you go to a new tab and make some change you can go back to previous state by clicking the icon in the bottom right corner (see the picture).
as you can see..you can "toggle between current settings and defaults for the visible panel"

Layout margin "Before" and "After settings

I'm working on a document where I sometimes need to alter the preset upper and lower margins of a given page. I can use the "Before" layout margin setting to move the text box tops downward but trying to move the bottoms of the boxes upward using the "After" setting seems to do nothing. Isn't that what that setting is for?

The Before and After paragraph settings are for adjusting the spaces between paragraphs. Put you curser in a paragraph and adjust the Before setting and the space between that paragraph and the preceeding one increases or decreases. Adjust the After setting and the space between that paragraph and the next one changes accordingly.
If you want to adjust the margins of the page, as well as the header and footer, use the Document Inspector.
If your're using text boxes, just move the box as needed. To move the entire box it should be set for Fixed on Page.

Detecting Before and After Field Images

Is there a way within ADDT to find the value of screen fields prior to update? I've tried using the custom trigger BEFORE and STARTER events; BEFORE is too late, the field is already changed, STARTER is too early, the field value is NULL.
I don't believe using straight PHP is an option either because I believe ADDT changes the names of the fields for occurence purposes.
I would like to produce a detail log of the fields that change. Comparing them before and after seems like the only way.

Heya,
I've really been having a hard time trying to understand exactly what it is you are trying to do. I read your post a few times and caught this line:
I would like to produce a detail log of the fields that change.
For this I would go about it by using an update record SB combined with insert into two tables SB. This would update the record of the user and also insert the info into a second table, the 'changed fields' table...
In 'changed fields' table insert logged in users id via session variable, a timestamp, and whatever fields were updated in the update record SB form and there you'd have it - your record updated and a detailed record of what fields were updated and when with complete backlog for all users. Query 'changed fields' table sorted by user id and you'd see who changed what when.
Hope that helps!
