Help Regarding File I/O in a procedure using Cursor

Hi all,
I am using a procedure, which uses a cursor, in this cursor we do some calculations and then write these calculations in a .csv file using utl_file package.
We have 2 approaches,
1. In every loop of cursor calculate and write then and there itself in the .csv file this means that file is open for total execution time of cursor.
2. In every loop of cursor calculate the values and at end of loop get the accumulated value in temporary variables and write into the file once, rather than in loop.
Which approach is better? Any visible proofs of which is better approach?
i. Our database server is a stand alone server.
ii. The file to be created is on same server.
iii. Our server is single CPU, single disk server.
iv. at a time only one user will access the file to write and that too everytime file is created with unique name having timestamp in its name.
Considering all these points, can you guys pls help me in deciding which is better approach, how and why?
Thanks in advance,
Avinash Bhamare.

Hi,
Thanks for the link,
But it is not what i am looking for...
My doubt is simple and regarding whether we should be doin the I/O operations on any file in a loop or outisde loop.
Thanks & Regards,
Avinash.

Help regarding accessing duplicate rows in a procedure

Hi All,
I have duplaicate records in my table. In my procedure, I have to access only one row and leave the remaining rows unprocessed.
For ex:-
EMPNO ENAME DEPTNO DNAME SAL
1128 SMITH 140 MARKT 200
1128 SMITH 140 MARKT 400
1128 SMITH 140 MARKT 600
1160 DARON 150 BUSSN 300
1160 DARON 150 BUSSN 500
1196 DAYLE 180 SPORT 800
In my procedure, I need to process only
1128 SMITH 140 MARKT 200
1160 DARON 150 BUSSN 300
1196 DAYLE 180 SPORT 800
only these rows and dont process the remaining rows. Instead of deleteing the duplicate rows and then accessing, how to handle this duplication in the procedure. will write a cursor and open it and process the first row. when the cursor fetches the second row, as it a duplicate interms of EMPNO, i dont want to process that and skip to 4th record. process 4th record and skip 5th as it is a duplicate and then process 6th.
Will write some validations to check whether EMPNO and DEPTNO exists in the database and and whether those two are linked to each other and then process it.
Help Appreciated how to handle it in a procedure.
Thanks

Hi there,
from my understanding of what you've asked, you should just need to ensure your cursor is ordered by "empno" and "sal" and then assign empno to a variable each time you fetch the cursor or loop arround depending on how you do it.
then you only process the row when the data in the cursor.empno field is different from the data in the variable.
e.g. (disclaimer: quick and dirty)
declare
v_empno number;
begin
v_empno := 0;
for v_cursor in (select * from table order by empno, sal) loop
if v_cursor.empno <> v_empno then
--process record
v_empno := v_cursor.empno;
end if;
end loop;
end;

Help regarding files after re-installing M. Lion

Hey everyone,
I stupidly deleted the VAR folder today when I was using DaisyDisk and didn't look into it before hand. I then had to reinstall Mountain Lion which worked succesfully adn didn't delete my files however they didn't come back in my normal user window but are still on my HD. I opened iTunes and nothing was in there, my folders on my desktop are gone etc etc. If I spotlight any of the files though they show up and also if I go into the Users folder it shows my old user but doesn't show up in the login pane for me to log into.
Is there anyway I can get my old user back with my files? As I said everything is still on my HD but for some reason Mountain line basically made a new user for me adn I can't access my old one.
I hope I have provided enough info for somebody to be able to help. Thank you in advance any help is appreciated.

If you have a hard drive and it's not Filevaulted you can recover the non-overwritten files with a external boot drive and a copy of $100 Data Rescue installed on it.
.Create a data recovery/undelete external boot drive
The software reads the 1's and 0's of the bits themselves, not going by what anything else says.
You have to quit using the internal drive/MacintoshHD partition particulary as the more your using it, the more it's writing over your files and less is recoverable.
Also it might be possible to see and grab the files without Data Rescue from the external drive.
Once you have your files, you just erase and install fresh and return those files into the new account and then #6 repair users permissions.

Help regarding file attachment

Hello All,
I am developing a form where the user will add details about a person.At the end there would be a button called "Add Photo" when the user clicks the button the add files dialogue will open. The user can browse through the photo and can add the Photo.The max size limited should be 700 KB.After the user has added the photo the photo would be shown as a thumb nail view. Also the user can change the photo later on .I am also thinking about : If the user clicks on the photo it would be displayed in its original size and one close button will appear on the bigger photo on the top right hand side corner.If the user clicks it then the photo will become thumb nail view once again. Is it possible to design in LiveCycle Designer 8.2 or am being too optimistic ?
Thanks.

Help regarding file name

Hi All,
I want to write my logging information into a file with filename <month><year>.log
How can I do this using the log4j xml configuration file?
Thanks, Sachin

I don't have the documentation here but you would use a DailyRollingFileAppender. If you are working with log4j then you should have the docs accessible. Check it out. If I recall correctly there is an example of that in the tutorial that comes with the product.

Procedure using cursor loop is taking lot of time!!

Dear All,
I have an existing procedure which works on top of a cursor which fetches around *4,00,000* records.
I have to loop through each record and make it go thru IF..ELSIF block of seven conditions.
And within each IF..ELSIF block condition, i'll have 2-3 select queries on tables accessed via DB links, and then if the values fetched via these queries match certain conditions data willl be inserted into a table and commited.
Running one IF..ELSIF block separately takes around two seconds at the max.
This procedure keeps running for around *4 hrs* and then gives an error as
ERROR at line 1:
ORA-01555: snapshot too old: rollback segment number with name "" too small
ORA-06512: at "<procedure name>", line 47
ORA-06512: at line 1
Then i used BULK COLLECT with limits 2000 and 500, and in both the cases i have never been able to completely run the procedure, as it takes more then 6 hrs and some or the other problem comes up.
And the problem is i cannot run it in a TEST env as the tables are huge, and have no option except to try it in Production environment.
I have a feeling that i have not been able to gather the correct info from the error mentioned above.
DB Version:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

Several questions regarding File Vault

Hi!
I have several questions regarding File Vault - right now I'm using Mac OS 10.4.8
1.: The battery lock of my iBook is defect thus it happens from time to time that while transporting it the battery drops out while the laptop is sleeping. What happens with the File Vault-disk image?
2.: I want to (have to ) set up my Intel iMac again. The installer-CD I have will bring it back to 10.4.6
AFAIK the data format used for File Vault since 10.4.7 is version 2. What happens if I encrypt my stuff now (10.4.8 - thus version 2), back it up to my backup disc, install a new system (10.4.6 - therefore version 1) and want to access my data via Migration Manager (don't want to use archive and install)?
3.: How do I actually do a backup of my data while the system is running? The backup should be encrypted as well.
I use the demo-version of SuperDuper for backing up my system because with it I can ensure that I have a complete bootable backup of my running system.
Thanks for your answers in advance
ibook g4 12" 1.2 GHz 768 MB RAM / Intel iMac Core 2 Duo 17" 2.0 GHz 2GB RAM Mac OS X (10.4.8)

Parker,
You said:1. If it did, Apple would not use FileVault, as everyones computer will have a battery problem once in their life, and Apple would lose buisness from angry people who lost all of their data.I have seen enough reports of data loss with FileVault that I feel compelled to dispute your statement.
In Data corruption and loss: causes and avoidance, Dr. Smoke writes...If your data-security needs demand FileVault, you should backup your encrypted Home folder regularly, preferably daily. Like any hard drive or disk image, a Home folder protected by FileVault — an encrypted, sparse disk image — does not respond well to the causes of data corruption...Loss of power definitely is a cause of data corruption.
For Niels....,
An Unencrypted Look at FileVault, by François Joseph de Kermadec is an excellent discussion of the features, pitfalls, and cautions regarding Filevault.
Although the article discusses Panther and is dated 12/19/2003, the concepts as they apply Tiger have not changed.
The cautions and warnings are prominent in any of the Apple Knowledge Base articles referring to the use of FileVault. If a user is unfamiliar with any aspect of FileVault, it should not in my opinion be activated.
As good as FileVault is in protecting your sensitive data, it also presents the danger of locking up your files in an irretrievable ball of one's and zero's. Backups are critical. You must ensure that you have a comprehensive backup plan. Backup and Recovery, by Dr. Smoke is a fine example of what you need to consider.

I am facing problem regarding graphical user interface. I am using text box for editing files. I want to show the line numbers and graphical breakpoints along with text box. Can anybody help me in this? Thanks.

I am facing problem regarding graphical user interface. I am using text box for editing files. I want to show the line numbers and graphical breakpoints along with text box. Can anybody help me in this? Thanks.

Thanks for you reply.
But actually I don't want to show the \ (backslashes) to the user in my text box.
Ok let me elaborate this problem little more.
I want to show my text box as it is in normal editors e.g. In Matlab editor. There is a text box and on left side the gray bar shows the line numbers corresponding to the text. Further more i want that the user should be able to click on any line number to mark specific line as breakpoint (red circle or any graphical indication for mark).

Critical issue regarding file to website interface

hi all,
I am working on one scenario in which sender is an File. and receiver is an HTML page(actually it is a website) which responds according on the input data.
when i visited that site I came to know that there are three fields. as follows...
username:
Password:
File: Browse
POST
Actually file name contains the contents of the file feilds which varies for every transaction.
When i manually put username password and location of the file(using Browse tab) in the website page, I got the response file.
But when I put just file name I am unable to click POST tab.
My problem is:--
Is this thing is possible using XI.
I tried using HTTP and put all three inputs in the header fields of receiver HTTP channel.
But i didn't get the response.
Can anybody tell me any other solution. Since it is critical requirment for me. so Plzz respond ASAP.
Solution will be awarded
Thanks

Hi,
you said that the target system is a website...so can i say that it is a WebService exposed by some XYZ system...if yes then why dont you opt for the receiver SOAP channel....the use of SOAP channel is in such cases only (source: http://help.sap.com/saphelp_nw04/helpdata/en/29/5bd93f130f9215e10000000a155106/frameset.htm )
Also if you have any doubt regarding what kind of adapter to use please refer this discussion: Re: Can't select Adapter Type during creating communication channel.
Adding one more link:
Difference between SOAP and Http Sender
Regarding the target url, u need to use the one which you can see after you hit the Post button.
In the receiver SOAP channel, under the Target URL option u can find the User Authentication details...enter the user details who is authorised to post/upload the document.

Abhishek.

No more connections available to this remote computer...Urgent Help for File server...

Hi Guys,
I need urgent help regards to our school File server which is having "No more connection to this remote computer error"
on SMB Shares where I usually authenticate with a domain username it used to work fine since till 3 weeks ago.
Now I can browse the SMB shares with only IP... Netbios gets straight away this error message from non-domain joined pc's where the computer needs to connect to the SCCM distribution point on this file server.
Strangely, Domain joined pc's does not have this problem at all they can use Netbios or IP no problem at all. But someone from a standalone laptop or desktop who needs to access shares through netbios gets this message.
Can someone help me please?
I did check DNS yet there is no problem on DNS I checked PTR record for the server to make sure it is not turned in to multihome accidently but nothing at all.
I also did a NETMON where I captured the data from server and the client I get these errors:

How to open external files in a Java stored procedure?

Hi y'all,
