What are the consequences of Compiling a trigger in peaktime in a Database.

Compiling a (table) trigger, would temporarily require a lock on the involved table.
So, no open transactions that involve the table can exist.
Since a trigger is a top-level object (dba_dependencies - wise), compiling it will not invalidate other objects.
Having said this: I would not advise doing this during peaktime...

What are the consequences of changing the scratch disc??

What are the consequences of changing the scratch disk? Everything was fine with my project until I tried to work on a new project for someone else. I uploaded new footage to a new session and changed the scratch disk to my other external hard drive. Now there is confusion with my initial project..

This is something we all live with. You have to be careful going back and forth between projects, if you are using different scratch disks for each. If you are editing a project on one scratch disk, then start a new project on another, remember to switch back to the original scratch disk when you go back to the original project. Otherwise render files will wind up on the wrong drive, or worse, you will capture to the wrong drive. Each issue is correctable by managing your media over to the proper drive, and deleting then deleting from the other.

Deletion of setup data : what are the consequences ?

Hello,
I am a sap basis guy, and currently perfroming an Upgrade (4.7-->ECC6).
during the preparation phase, I had some problems with BW estraction data that correspond to the symptoms described
in sap note 1083709; I executed the report RMCEXCHK and deleted the content of the setup data "02" and "11".
This is still harmless , as we are in the QAS system, but I'm concerned about the upcoming upgrade of the production environneemnt.
What are the consequences of deleting the setup tables ?
I'm really confused about what need to be done after the upgrade, regarinf the BW setup tables that have been emptied :
Do you know if :
The setup tables "02" and "11" should be reconstructed ? This should be done when no users are connected?
BW delta loads "02" and "11" will still be operationals ? Or do we need to plan new BW initializations ?
are there any others side effects of deleting the setup tables ?
Thank you in advance for your help.
Regards.

Hello,
Before upgradations all the users will be locked and there wont be any transactions in the surce system....
concerning to delta queues there....All the data have to be extracted before upgradation from delta queues into BW this is important.
Concerning to setup tables....there wont be any problems if you delete, because there wont be any oads going on at this time....
Its always preferable to have some sort of communication with BW guys at upgradation time, make one check list what need to be done before upgradtion and after upgradtion...speak with BI people they will explain their steps...and as a basis guy you can prepare your check lists.
Filling of setup tabless....no need to be done from your side that BI people will do if it is required.
no initializations required after upgradtions.

What are the consequences of De-Authorizing all computers.

I've had an iTunes account for years and its only fairly recently that i've been a bit more aware of the authorizing of computers.
I've hit my limit of 5 but 3 of these are computers that i no longer own and don't have access to. I have made purchases, have an iPod Touch with Apps. What are the consequences of De-Authorizing all computers.
Will it cause me problems with my purchased content and registration of my iPod Touch (don't want to lose any content) or is it just a case of providing my apple id when first listening to purchased content.

You won't physically lose anything. You will just need to reauthorize the computer(s) that you actually have.
Best of luck.

What are the consequences of using mismatched wattage power cords on macbooks?

I am fortunate enough to have a macbook air, a macbook pro, and a macbook at my house. Sometimes the power cords get mixed up. What are the consequences of using the lower wattage macbook air power cord with the macbook pro and vise versa?
Paul

It will work but it isn't recommended. The PSU of the MBA will be charged for the maximum amount of power it can deliver so it might break sooner than normal, but I doubt you'll ever notice it if you're not doing this on a daily basis. It might also be possible that your MBP will not charge (as fast) from the MBA PSU.
The other way around is no problem since the device will only ask as much power from the PSU as is needed.

I overcharged my ipad 2 battery for about 3 hours. what are the consequences, i overcharged my ipad 2 battery for about 3 hours. what are the consequences

i overcharged my ipad 2 battery for about 3 hours. what are the consequences? and there are these tiny fibers and dust that enters insideipad screen. how will i clean them. .please help

Relax, you cannot "over" charge it. The built in charging protection ensures it will not overcharge the battery or do any damage leaving it plugged in. Many folks (myself included) leave our iPads and iPhones plugged in overnight, all night, so they are charged and read for use the next day.

What are the benefits of compiling in a fakeroot environment? [SOLVED]

Out of curiosity, what exactly are the benefits of compiling packages in a fakeroot environment? There are a couple packages I've had to compile manually before running makepkg because they wouldn't compile in a fakeroot environment, and was just wondering what the benefits are as to why all packages are compiled in such a way (without an option to disable it).
Last edited by deltaecho (2009-02-22 22:38:03)

I only know of downsside and problems doing so. Only installing needs to be done within fakeroot. Next version of pacman will support separate build and package function to solve this issue.

Can I interrupt a migration from Mac Book Pro to Imac and what are the consequences

can I interrupt a migration from Mac Book Pro to iMac and what are the consequences

Les:
Here are some options:
• You could copy the data file to your laptop, work on it, and update the file on the iMac when you are back.
• You can use an application like Log Me In to access your home computer from your laptop.
• You can use DropBox. Install it on both computers, place your data file in a folder on the iMac, access it and work on it on your laptop and it will be automatically updated on your computer at home, even if it is not turned on, as soon as it is connected to the internet.
Please do post back with further questions or comments.

What are the consequences of an IOException?

Hi,
my program connects as client over TCP/IP to a server and reads/writes data. Whether read and write of Input-/OutputStreams of the socket or readLine of a wrapping BufferedReaders, all can throw exceptions, particularly IOExceptions.
My question now is, what does that mean and how to handle them?
On write the API documentation says "[...] if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.", on read "If the first byte cannot be read for any reason other than end of file, or if the input stream has been closed, or if some other I/O error occurs." or simply "If an I/O error occurs".
Now to appropriately handle those situations I should know what it means and what the consequences are. An exception on a connect surely means no connection is established. On read and write nothing has been read or written. But does the connection itself still exist or not?
Secondly I often read to try/catch as late as possible, not around every call that is declared with throws. But then you're losing detail information of which call actually threw the exception and you only know that "something IO related went wrong".
I think the most secure would be to view the connection as broken, disconnect (closing all streams and sockets of the connection) as a precaution and start over from the beginneing. But on the other hand this might be overkill.
So what do your IOException handlers look like and where are they?

An exception on a socket I/O operation means the connection and the socket are hosed, no further communication is possible, and the only sensible thing is to close the socket. I rarely find it necessary to tell socket exceptions apart, other than logging them; they all mean it's dead, Jim.Thank you, that's a pretty complete and usefull answer. So I wouldn't overreact calling my disconnect method (which tells the rest of the app that it's offline).
UnknownHost and Co. can be caught separately for error reporting but you're right in forwarding e.message should be best. Only problem might be localised applications where users want to have localised error reports (getLocalizedMessage mostly likely isn't overwritten).
The (AFAIK only) exception to this is SocketTimeoutException after which the socket is still fine. You'll only get those if you ask for them (socket.setSoTimeout()). Then you'll need to arrange your code suitably so you can deal with them.Yes, that I figured myself. But after experimenting I found this feature of no use for me anyway.

What are the consequences of not backing up controlfile in hot backup.

Hi All,
We have 8i,9i, 10g and 11g database. The unfortunate thing is that we are using this user managed hot backups for backing up our database. and I have no idea for what reason, we are not backing up the controlfile. Anyway, I would like you to comment on this, they said, they will recreate a text based controlfile and do the recover database until cancel using backup controlfile ; I know, if we have the path of all the datafiles , we can use this, but is this a right strategy ? of course, no one would agreed on this. I really appriciate, if somone could express his opinion in detail.
Regards

Hi,
The database consists of the following files:
Spfile/Pfile
Controlfile
Datafile
Redo Log
archivelog
When we talk about backing up the database, (no matter how) must take backup up of all these files.
If you are not taking these files in your backup you have a incomplete backup.
Why not take a back up of control file to a binary file. Is more simple and fast restore controlfile using binary file.
ALTER DATABASE BACKUP CONTROLFILE TO '/oracle/backup/control.bkp';To Trace should be used to produce SQL statements that can later be used to re-create your control file.
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;Why not use RMAN? A resource with endless options and features.
Using user-managed backup you have none options/feature compared with the use of RMAN.
It can be used in all Oracle databases without additional license.

What are the user-exits which will trigger on saving Sales Order

Hello Experts!!!
I am working on Sales Order VA01. The requirement is I need to pre populate Sold-to-Party field. I find out user-exit (V45A0002 Predefine sold-to party in sales document ). So it is working fine.
Now second requirement is I need to capture all the date once user saves Sales Order. Also the time or Sales Order creation I have to make u2018GRAYu2019 some of the fields so user cannot change the value. Can anybody tell me which user-exits should I use to retrieve the entire information user entered and lock fields in Sales Order screen?
Thanks a lot on advance.

Hi
U can't find it there,because it's a include, not enanchement.
So u need to use the trx SE38, not CMOD.
For sales ored there aren't the enanchements, but only some FORMs defined in particular includes.
U need to get the access key by OSS in order to change them.
These are the rest of the includes where u can find other exits:
       INCLUDE MV45ATZZ.            " Data definitions in MV45ATOP
         INCLUDE MV45AOZZ.             " User-modules PBO
         INCLUDE MV45AIZZ.             " User-modules PAI
         INCLUDE MV45AFZA.             " User-forms < 3.0
         INCLUDE MV45AFZB.             " User-forms
         INCLUDE MV45AFZC.             " User-forms < 3.0D
         INCLUDE MV45AFZD.             " User-forms   3.0E
         INCLUDE MV45AFZF.             " User-forms   3.0F
       include mv45afzg.             " User-forms   3.1G
         INCLUDE MV45AFZH.             " User-forms   4.6B
         INCLUDE MV45AFZZ.             " User-forms
         INCLUDE MV45AFZ4.             " User-forms   4.0
Anyway u can find some information about these exit in customizing (trx SPRO):
Sales and Distributions->System modifications->User exits

After installing security update 10.6.8 I've seen dialog boxes asking me if I will permit certain root processes, e.g. configd, to receive unsolicited messages from the internet. What are the consequences of denying these requests?

After installing security update 10.6.8 last night I've seen dialog boxes asking me if I will allow incoming network connections to certain root processes, e.g. configd. I didn't see these dialog boxes prior to installing 10.6.8. How do I make informed decisions? In other words,
(1) Where can I find 25-word summary descriptions of these processes?
(2) Where can I find discussions of the consequences of granting or denying these requests?
Alternatively (and at some risk of revealing metaphysical doubt) why am I being asked for these permissions? And who expects me to make correct decisions?
I have turned on th standard-issue OS X firewall and am running my system in stealth mode.

What are the consequences of ServerSession.removeFromIdentityMap()

We have external processes that update the data in our database. As a result we must invalidate and/or refresh portions of the ServerSession's identity map when these external changes are committed to the database.
Given the following situation:
A process initiates a query through the toplink ServerSession. The objects from that query are cached by the ServerSession's identity map. This process then begins a transaction through a UnitOfWork to update an Object (TestObject). During this transaction an external process updates data in the database that our TestObject represents. The TestObject is removed from the ServerSession's identity map through ServerSession.removeFromIdentityMap( Object ourInstanceOfTestObject ). When the transaction from our UnitOfWork is committed, what happens?
Is the UnitOfWork operating on a clone of the object in ServerSession's identity map or is it operating on a reference to that object?
Any light that could be shed on this would be greatly appreciated.
Thanks,
Andrew Lee

Hmmm... I just did a quick test case, and it looks like at commit time TopLink updates the object you removed from the identity map, and even politely puts it back into the cache.
Make sure you have an optimistic locking policy, or you're going to get last one wins on the database. I can't comment if this is deterministic behavior between releases, i.e., not sure if this is intended behavior or just the way it happens to be...
Here is my test case:
Player p = (Player)serverSession.readObject(Player.class);
System.out.println("READ IN PLAYER: " + p);
System.out.println("EXISTS IN IDMAP: " + serverSession.containsObjectInIdentityMap(p));
UnitOfWork uow = cs.acquireUnitOfWork();
Player pc = (Player) uow.registerObject(p);
pc.setName(pc.getName()+"i");
System.out.println("REMOVING FROM IDENTITY MAP..." + p);
serverSession.removeFromIdentityMap(p);
System.out.println("REMOVED!!!");
System.out.println("EXISTS IN IDMAP: " + serverSession.containsObjectInIdentityMap(p));
System.out.println("COMMITTING");
uow.commit();
System.out.println("JERSEY OF P IS: " + p);
System.out.println("EXISTS IN IDMAP: " + serverSession.containsObjectInIdentityMap(p));
System.out.println("== " + (p == serverSession.readObject(p) ));
Here is the output:
ServerSession(69)--client acquired
ServerSession(69)--Connection(72)--SELECT NAME, HOMETOWN, POSITION, ID, TEAM_ID FROM PLAYER
READ IN PLAYER: Player: No.null Giroux, Raymond From North Bay, Ont D
EXISTS IN IDMAP: true
ClientSession(76)--acquire unit of work:75
REMOVING FROM IDENTITY MAP...Player: No.null Giroux, Raymond From North Bay, Ont D
REMOVED!!!
EXISTS IN IDMAP: false
COMMITTING
UnitOfWork(75)--begin unit of work commit
ClientSession(76)--Connection(73)--begin transaction
UnitOfWork(75)--Connection(73)--UPDATE PLAYER SET NAME = 'Giroux, Raymondi' WHERE (ID = 10)
ClientSession(76)--Connection(73)--commit transaction
UnitOfWork(75)--end unit of work commit
UnitOfWork(75)--release unit of work
JERSEY OF P IS: Player: No.null Giroux, Raymondi From North Bay, Ont D
