What is the effect of changing the physical location of data files

Hello,
Here is the situation:
We have 2 physical hard disks (that's right - 2 separate disks). Their logical drives are respectively C: and D:.
We have an Oracle 9i2 database installed on the first disk C:. We have one database with datafiles on D:.
We want to replace the second disk (with the data files) with brand new one. So here is what we did:
1) We mount the disk and we named it drive F:
2) We stopped all Oracle services
3) We copied all data files from D: to F:
4) We remove the disk with letter D:
5) We renamed the disk F: to D:
So, now the new drive D: has identical structure as the old one.
Before starting the Oracle instance, I would like to ask: Is everything going to be OK when I start the service? Do we need to do something else?
As far as I know Oracle has internal addresses (ROWID) for the data so I think that changing the phisycal addresses of the files won't be a problem. Am I correct?
Thanks in advance.
Best regards,
Beroetz

I think your database can not be opend in this case.
If you follow this method,you can move a datafile to a new address.
1.alter tablespace tablespacename offline normal.
2.move datafile to new folder as you did
3.alter tabespace tablespacename rename datafile 'old datafile including fullpath' to 'new datafaile including fullpath'
4.alter tablespace tablespacename onlin

Help! what is the default location for shared file system?

Help! i came in this morning and for some bizarre reason the shard file system information had disappeared and podcast producer wouldn't work i thought it was in library/quicktimestreaming/movies so i set it to there but when i try and submit a video i just get question-marks in the post where the video should be its obviously not finding it. So i found where most of the previous videos were which is a folder called Podcast Producer which seems to be a link to my external drive but when i set the shared file system to this folder it creates a new folder called podcasts and sticks them in there so i get the same question-mark scenario. Its bizarre i can't figure out why it would losse the information in server admin the only thing i can think of is that i did a repair permissions and wondered if it might have set some permission on the shared filesystem folder differently and made it somehow inaccessible does anybody know what permissions should be set on the folder? Also regarding quicktime streaming does this location have to be the same as the shared file system folder?

Thanks - The folder was hidden, so once I changed my options to see hidden files, I was able to find it exactly where the link told me it would be.
Much appreciated!

What is the Difference Between Sys Date and Effective Date ??

Hi Gurus,
Can any one pls let me know What is the Difference Between Sys Date and Effective Date ??
with regards
User600722

EFFECTIVE DATE usually refers to a date-tracked record (although not exclusively).
Date-tracked records in Oracle HR have an EFFECTIVE START DATE and an EFFECTIVE END DATE. The record is 'EFFECTIVE' between these dates. In reports, you often use SYSDATE to compare to these two dates to find the CURRENT effective record, e.g. SYSDATE BETWEEN EFFECTIVE START DATE AND EFFECTIVE END DATE.
When you make changes to a HR record, you can choose between DATE TRACKING options, such as CORRECT or UPDATE (there are others too). CORRECT will overwrite the record and replace the data with your changes. This is normally used when you need to correct something that is wrong. UPDATE will create a new version of the record from the EFFECTIVE START DATE you choose. It will also set the EFFECTIVE END DATE of the previous record to the day before your new record's EFFECTIVE START DATE. That enables a history of records to be maintained so you can see what your data looked like at ay one point in time.
Regards
Tim

Hyperlink - The physical location in the page

When I export the A PDF file, how do I know the physical location of the hyperlink in the output page (coordinates)
I need to export from Indesign
- Hyperlink physical location (# page & XY coordinates)
TIA

I guess I'm misunderstanding the question, then.
I don't quite understand what you're trying to accomplish with this task. How does Excel factor into this? What value is it to have a report of x and y coordinates for an Acrobat page? This sounds like something you'd need for html coding, not a print document. If so, the pages should be exported as html pages, not Acrobat pdf files, from your original. I only ask because I have a feeling you might be creating way more work or expense for yourself than you need to be. The more information you can provide, the better advice you'll probably get.
If you need a report of x and y coordinates, I'm thinking Acrobat is the wrong application. It's not really a web design app. I don't have Dreamweaver here at my office, but I seem to remember that all that information is available if you open your pages in Dreamweaver, and there may be a way of extracting a report with just what you need. You might try asking your question on the Dreamweaver forum, if that's the route that makes more sense for what you're trying to do.

What is the use of inverted date format

In table TCURR - Exchange rates, the field GDATU - Date As of Which the Exchange Rate Is Effective is stored as an inverted date. So 01/01/2008 is actually stored as 79919898.
What is the use of inverted dates. Why does SAP use them. Why not just use normal date format? If I want the latest record from the table, instead of sorting by descending, I actually have to sort by ascending because the date is stored in inverted format.

Hi,
Inverted date is a old concept which helps in soring the dates sometimes. but now ASCENDING and DESCENDING sorting is more easy and quick. Check this application help. maybe useful for you
1. CONVERT DATE f1 INTO INVERTED-DATE f2.
2. CONVERT INVERTED-DATE f1 INTO DATE f2.
Effect
Calculates the nine's complement of the internal date format (YYYYMMDD - for more information about internal display, meaning and initial values of types, see TYPES) and places it in the field f2. For example, 19950511 becomes 80049488 and 80049488 becomes 19950511.
In the inverse date format, the most recent date has the numerically smallest value. You can make use of this effect when sorting dates.
Note
The technique of manipulating the sort sequence of dates by inverting the internal date format is now rarely used. You can sort internal tables in order of ascending or descending date values much more efficiently using the ... ASCENDING or ... DESCENDING additions to the SORT statement.
Example
DATA DATE_INV LIKE SY-DATUM.
CONVERT DATE SY-DATUM INTO INVERTED-DATE DATE_INV.
Suppose, for example, SY-DATUM contains the date 11.05.1995 in its internal format 19950511. After execution of the CONVERT statement, DATE_INV would contain the internal format 80049488.

What is the diff b/w flat file and legacy system?

Hi everyone,
when v say v r working on scenario FILE to FILE? which format of file r v usually working on? and what is the diff b/w flat file and legacy system?
thanx

Hi,
<i>when v say v r working on scenario FILE to FILE? which format of file r v usually working on?</i>
>>>Many a times it will be a Flat file with CSV format,Tab delimited format, fixedlength fields.
<i>what is the diff b/w flat file and legacy system?</i>
>>>We can not differeniate like this..
Flat file may come from any systems, it may be live system or legacy system.
Legacy system- is something like old, or past one. If you talk about SAP , then older versions of SAP can be called as a legacy system.
So it may be a file system, or any system which is old version but it doesnot mean it is not in use,

What are the settings for apn data and mms for iphone 4 on straight talk?

what are the settings for cellular data network APN DATA and MMS for Straighttalk sims on IPhone 4?I cant send or recieve pictures.My service keeps losin signal constantly saying no service then 1 bar,2 bars,3 bars...then back down to no service.It drops calls.Iv been trying to find out the answer to this problem for 2 weeks!I have no Profile selection in my settings either to do wat its showing online on one website.and have entered numerous diffrent APNs and none have worked!!!!PLEASE HELP!!!

They're asking a question about carrier settings for their iPhone. I think that has everything to do with Apple.
Maybe they did already ask Straight Talk. I've called Straight Talk before... they're not too helpful.
You know, this forum would be much friendlier if people in this forum would quit squabbling, & posting comedic replies, not too mention name calling (like I did), when people are just needing some help.
It's also frustrating that people stick up for the guy who doesn't help, but rather takes the time to post some smart alec reply. Granted, I shouldn't have name-called... some people just frustrate me when they act like that.
Admittedly, there ARE some grey areas when it comes to carrier questions... but let the moderators do their job when someone is asking innappropriate stuff. And if the mods aren't chiming in, then that's a good indication that what the thread is about IS in fact Apple related.

Because i commented the above line & compiled, so it is not giving any error now.
So please tell me what win_api_environment.read_registry does??
it's read windows registry value. So, no problem if you comment it.

What is the benefit of Using Data Adaptor

Hello
I wonder that What is the benefit of Using Data Adaptor ? I don't know TopLink Technology , inorder to using Data Adaptor I should know toplink but what is the advatages of using BPEL database adaptors in conditions thet I can make webservices by making plsql web services or exposing ADF application modules more easier?
I think that if I use Data Adaptor (based of Toplink) I can use JTA feature for transaction managment , am I thinking Correct?
for example I can invoke to webservice A and the B in BPEL process with two DB adaptores (by global transaction ) such that if A failes the process automatically roles back the B transaction without need that I manauly compensate the undo process
please help me ?

Thank you for your very useful comments about DB adapter
I tried again and I have Successfully deploy and test my DB adapter with using # for parameter.
But I have another question : We have ADF Application that using ADF bc for user data entry supporting in use case scenario , but we want to call web services (eg BPEL) in save operation instead of ADF application modules Normal commit !
If we want using Data adapter for persist the Data that user entered by UI , we must write a lot of Insert or Update statements in DB adapter because of lot of database entities.
How can we shorten this production scenario in our Project?
