Sorting problem in 10g
dear all,
We have a new 10g database and have loaded a dump from 9i. We followed all procedures as written in documentations. The database is working fine but we experience one problem.
We connect to the database with our application that was developed in Powerbuilder. Reports we run from this database gives the same results as in 9i database except the records do not adhere to sorting condition given. Below is the example
in 9i report results
tax type amount
Payee 1000
Corporate tax 200
Oil Levy 420
Withholding tax 80
Total 1,700
in 10g report results
tax type amount
Oil Levy 420
Withholding tax 80
Corporate tax 200
Payee 1000
Total 1,700
Why the records are not arranged in the proper manner in 10g while the application used is the same?
Thanks and regards,
Steve
Thanks Peluka.
But even I don't enhance the vendor search help, I still found that the original standard version has this problem after sorting.
Is that the program bug?
Have anyone encountered this problem before?

Sorting Problem in FND_MENU_ENTRIES_TL Table
Hi,
FND_MENU_ENTRIES_TL Table storing the record FND_MENU_ENTRIES_TL_N1(MENU_ID,PROMPT,LANGUAGE) wise in R12. But whereas in 11i, records stored FND_MENU_ENTRIES_TL_U1(MENU_ID,ENTRY_SEQUENCE,LANGUAGE).
I am confused, whether i need to recreate the index in R12, so the records will get store MENU_ID,ENTRY_SEQUENCE,LANGUAGE wise.
Could any one please suggest me how to resolve this problem.
Thanks,

Hi, I'm having a bit of a sorting problem when it comes to an artist with name variations. The example I'm going to use is DJ Tiesto.
There are album I have where he is credited as DJ Tiesto, and others where he is simply Tiesto.
In the end, I'd like these albums sorted chronologically under one name (say DJ Tiesto), while still preserving and showing the proper artist name for each album. I have it set to sort by "Album by Year", which is working fine.
The major problem I am having is that I can't get it to display properly across all iTunes viewing methods: List mode, Grid mode, and Coverflow.
I've tried leaving the Artist field alone, and changing the Sort Artist field to "DJ Tiesto" for all songs, and that almost works:
-List mode groups them all under "DJ Tiesto", while showing each albums Artist as the correct artist name.
-Grid mode sorted by Album groups them all under "DJ Tiesto", while showing each albums Artist as the correct artist name.
-Coverflow sorts them all in chronological order, while showing each albums Artist as the correct artist name.
Problem is, Grid mode sorted by ARTIST creates two separate artists! Some for DJ Tiesto and some for Tiesto!
To correct this I tried changing the Album Artist field for all songs to "DJ Tiesto", which solved that problem but created a bunch of new ones:
-List mode is still correctly grouping them under "DJ Tiesto", while showing each albums Artist as the correct artist name.
-Grid mode sorted by Album is still correctly grouping them under "DJ Tiesto", *however now it is not displaying the correct Artist name for each album!*
-Grid mode sorted by Artist is now grouping them all under "DJ Tiesto", *however it is not displaying the correct Artist name for each album!*
-Coverflow is sorting them in correct chronological order, *however it as well is not displaying the correct Artist name for each album!*
Using the Album Artist tag has created more problems that it has solved! Is there anyone who knows a way to achieve what I am trying to do? I have tried seemingly every option I can and have still not found a way to do this!!
Thanks!My own method of working involves renaming the files upon import to:
i "shotdate_sequencenumber"
Files are therefore typically named
b 2007-11-25_001
etc.
This way, sorting by Filename automatically sorts by Date by default. And it wouldn't even matter if you added a descriptive text in between the date and number (
b 2007-11-25_Scotland_001 -
Sorting problem in standard vendor search help
Hi all,
I'm enhancing the vendor search help.
I found that there is a sorting problem in the original standard search help.
The 1st time to search vendor in the search help returns a correct list, then I just sort the vendor in ascending order. This time the column name of the hit list changes and mismatch the actual values.
Any one faced this problem before?
What's wrong are there ?
Thanks.Thanks Peluka.
But even I don't enhance the vendor search help, I still found that the original standard version has this problem after sorting.

Catalog Migration Problem from 10g to 11g
Hi,
When i am trying to migrate catalog of 10g to 11g. They have some problems
1. In obiee 10g (under root folder) it shows only around 5 dashboards. But actually when i am seeing in the I catalog manager of obiee 10g it shows 12 dashboards and pages.
Can some please help me on this how to see the other dashboards and page in obiee 10g ( under root folder ).
2. When i am trying to migrate the catalog folder in obiee 11g it also shows around 5 dashboards. And other dashboards are not seeing after migration.
Can someone please help me on this how to see the other dashboards and pages in obiee 11g as well.Hi,
In Webcat, there can be some contents that are inconsistent/invalid. And such contents have 0 byte size. Please check if dashboards files that are not visible and their corresponding .atr files have 0 byte size.
Other possibility can be dashboards are hidden for the user-id you are using for login.
Please mark as helpful/correct if this reply helps.
Thanks,
Vijay

Hello!
I'm using Oracle 10g XE on Windows Server 2003, the installation was successfully realized.
The problem is that I can't access to the login page : http://127.0.0.1:8080/apex . I think that the problem come from a port restriction (but I'm not sure!) : the 8080 port is certainely blocked, but I don't know how open it ...
With Windows XP Pro, I had no problem ... ! Nevertheless I used the same anti-virus program with the same rules ... !
Can someone help me please, I'm loosing my hair !!

Problem Oracle 10g database Installation on Windows 2003 Server
Hi All,
I am trying to face some problem to install oracle 10g database on windows 2003 server with service pack 2. Once I start to installation it give me an error "Error in writing to directory 'c:\documents and settings\administrator\local settings\temp\orainstall2004xxx'. Please ensure that this directory is writable and has at least 45MB of disk space. Installation cannot continue"
I double-insured that there is enough disk-space and I am also in the Administrators-Group.
Please guide me for the above problem although I have done oracle 9i database installation with the same configuration.

Problem with 10g and 9i in one machine
Hello,
I installed 10g in a pc where 9i is already installed. It was installed in its own home directory. My problem is that when I try to access it using Enterprise Manager, or Sql*Plus, or Developer, I get either the service name could not be resolved, or cannot allocate a dedicated server. The service is up and running.
The curious thing is that I can access it with the command from a command window:
sqlplus
'scott/tiger@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=CAC403JN.EBOT.CA)(PO
RT=1521)))(CONNECT_DATA=(ORACLE_SID=ANEC)))'
Both the 9i and 10g have the same HOST and PORT but different SID.
How do I fix my configuration so I can access 10g using the using tools?
Help.
Thanks,
gkIf you are using local naming (tnsnames.ora file) and you have multiple Oracle Homes, one of two things has to happen
1) Every TNS entry has to be duplicated in each tnsnames.ora file.
2) You need to create a TNS_ADMIN environment variables that points at the location of the single tnsnames.ora file that all applications should use.
My personal preference is to go with option 2.

Hi,
I'm using the sort on a report with 7 columns. For each column I've specified
the sort sequence from 1 to 7. The last sort is a date field. If i sort now the
last column and i change to next report side the sort change jump to the first column.
Is there somebody who had also a problem like this?
Greets,
TomYou can check boxes to determine which columns can be sorted; if you check one or more boxes, you also need to set the "Sort Sequence" attribute under the "Report Attributes" tab of your SQL query region. So to use sorting you must.
1. ensure you don't have an order by in your SQL statement
2. check one or more "sort" boxes
3. set the default order in one or more column in the "sort sequence" column
Hope this helps,

Sorting Problem in XML Publisher Report
Dear Members,
I am facing problems with sorting data in my XML Publisher Report.
We are using Oracle E-Business Suite 12.1 Version and i developed a rtf Template and executable is an RDF which generates XML Data.
I want the whole report to group by element ITEM_NAME which is a character in the ascending order. I tried several ways but it is not working properly.
I don't know how to upload the RTF template in this forum. I tried to post the XML Code and since its excceds 30000 characters i cant post it in the forum.
Any help is greatly appreciated.
Thanks
SandeepYou can't upload the template here; you can post a part of the relevant XML code and template code here.
or send me a sample XML and RTF template to [email protected] and I will take a look. -
Mail sorting problem after upgrading to Mountain Lion?
I have a strange problem with Mail after upgrading to Mountain Lion.
Before upgrading, when I tried to search my Mail Inbox for e-mails from a specific sender, the esearch results would be indexed by the name of the sender. For example: when I entered 'John Smith' in the search box in Mail, it would display a list of email from 'John Smith'
Now after upgrading, the same query indexes the search results by the 'To' address i.e. my email address.For example: if my name is 'Steve Johnson', a search for 'John Smith' in the search box in Mail displays a list of email to 'Steve Johnson' and not from 'John Smith' which is how it used to display before.
My emails are sorted by Date always, and I am using the default Mail view [not classic view]
Can someone please help with a fix for this to help me get back to the original display I had while searching? Thanks in advance.I'm having the same problem. It's incredibly annoying!!! Did you find an answer?

Help with Artist Sort Problem Needed...
This is a bit long, so I'll start with the three main questions and below them is the backstory and detail of the problem (I did do a search but nothing turned up):
1) Does anyone know how to fix artist sorting issues where the artists are properly sorted (alphabetically by last name and band name) but there are constant grey-bar letter headings for the first name (sorry...I don't know how to explain better than I do below in detail)
2) Will re-setting the Touch require I have to...
a) re-add all the songs I've manually selected again
b) re-input any data saved to apps (such as CarCare and
Pocketpedia) and if so, can I backup that data first?
3) If all the re-doing in 2 above is necessary if I were to re-set the iPod, can anyone think of an alternative fix that would avoid a reset?
I might be able to get to an Apple store this weekend to ask a "genius" but I'm not that confident in them since I was given some incorrect information on how the Touch handles playlists at the time of original purchase.
Okay... now, what happened:
I'm not sure what to make of this, fortunately playback and all main functions are unaffected. I have my iPod Touch 2g set for manual sync. Today, while I was charging it at work, my PC (WinXP) froze. I gave it plenty of time to unfreeze, but eventually had no choice but to do a hard reboot while the iPod said "syncing." I slid the slider to cancel the sync, but the iPod didn't respond. I unhooked it from the PC and it unfroze. I shut it down and re-started.
Everything seemed fine after the iPod reboot except that now, while the artists are still sorted alphabetically (I've manually set artists to sort by last name), there are headers using the first letter of the first name between each artist. So, for instance, this is how the top of my artist list looks now (lines below with just a letter are the grey divider bar with the alphabetical header):
R
Ryan Adams
D
Dave Alvin
T
Tori Amos
E
Eric Andersen
A
Apples in Stereo
Arcade Fire
L
Louis Armstrong
A
Ataris
...etc.
This problem has not extended to album or song title fields, but for some reason, when scrolling through the album view using the index on the right, it moves fine until "O" -- then it sits still as I scroll down until it gets to "#", at which point it's resposnive again.
I've checked the music library on the iPod via iTunes and the artist sort fields are still correct.
Suggestions? I'm new to the Touch and am leery of doing a reset yet since it's taken time to figure out which songs from my 100+gb library to manually put on this. Also, I have no idea how it will affect the apps I've downloaded. There are some where I've saved data (such as CarCare and Pocketpedia) and I REALLY don't want to risk having to re-input all that data.
To anyone with any words of advice, thanks in advance.

Message was edited by: IronWaffleThis is an answer to only qestion 2. Yes restoring your ipod will delete all songs, apps, videos, etc., but you can back up settings like a passcode lock or screen brightness. But it will ask if you want to back up settings. If your'e on windows, in itunes go to file and down almost all the way you will see a "Tranfer purchases from (ex.) steves ipod" and that will make sure you have all your apps and music and other stuff.

JTable sorting - problem when adding elements (complete code inside)
I�m writing this email with reference to a recent posting here but this time with the code example. (I apologize for the duplicated posting � this time it will be with the code)
Problem: when adding more elements to the JTable (sorted) the exception: ArrayIndexOutOfBoundsException is thrown.
Example: If the elements in the table are 10 and then the user requests for 8 � the table will produce the correct result. However, if the user will ask for 11 items (>10) the exception will be thrown.
The program: The program below (compiles and running). A JTable is constructed with 3 items, when you click the button - the return result should be 4 items - this will generate the error, WHY?
I would highly appreciate your thoughts why this is happening and most importantly � how to fix it.
Thanks a lot

}The table listens to the TableModel for changes. Changing the table by adding/removing
rows or columns has no affect on its table model. If you make changes to the table model
the table will be notified by its TableModelListener and change its view. So tell
MyTableModel about the change of data:
public class TableSorterDemo implements ActionListener
MyTableModel tableModel;
public TableSorterDemo()
defaultListModel = new DefaultListModel();
init1();
tableModel = new MyTableModel(defaultListModel);
TableSorter sorter = new TableSorter(tableModel);
public void actionPerformed(ActionEvent ae)
if (ae.getSource()==clickMe)
defaultListModel.removeAllElements();
init2();
tableModel.fireTableStructureChanged();

Problems installing 10G (r 10.2) on Windows 7 64-bit
Hello. I am taking an introductory Oracle SQL class. The professor gave us a link to install Oracle 10g release 2, which I followed and performed on my Windows 7 64-bit laptop. The installation seemed to run through okay. When asked (again, per instruction), I created a database named CIS276 (the class name) instead of "orcl" as suggested during the setup. I am having problems getting connected to the database, however, and since the class is online, I can't go to our campus to sit down with the professor to work out where the trouble is, so I'm hoping somebody out here can help me. Here's where I am:
I am able to get to the Enterprise Manager through the loopback address and port that was given to me during installation. I am able to log into EM using the SYS account with the password I entered during install. I get to a screen that has a button labelled "Startup/Shutdown." When I click that button, I am taken to a screen asking for Host credentials (OS account name and password) and database credentials (I use "SYS", the password I created, database is already filled in, and "SYSDBA" for "Connect as"). After entering this information, I click on OK. I get an error message at the top of the screen saying: "Couldnot contact the agent. Verify that the url for the agent is null." I looked up this string and a suggestion was to run " lsnrctl status"--I think (I've been trying a lot of things over the past couple of days to try to get this running) and the program replied that the environment variable "ORACLE_SID" wasn't set. I looked up what I was supposed to do and went into Windows 7 Environment area and set the value.
I rebooted the computer and tried again and am still getting the same problem. So I Googled the error message again and saw a suggestion to stop and restart dbconsole. When I did that, I got an error (stopping and starting) telling me that I was denied access.
At this point, I felt I'd better stop and get any suggestions from more experienced Oracle users. If anybody could give me some suggestions as to what to try next, I'd truly appreciate it.
And one other question: when I followed the link to download Oracle, there was another download listed called something like "Companion Disk 2". Is this a necessary download or is it just extra stuff that I may not use for now?
Thank you again.
Eric S. BaumanHi Eric,
I thin your problem is not related to Operating System. Right now I also use Windows 7 64 bit. and the oracle database that i used is Oracle 10g (10.2.0.3) for windows vista 64 bit. still up and running good.
"I am able to get to the Enterprise Manager through the loopback address and port that was given to me during installation. I am able to log into EM using the SYS account with the password I entered during install. I get to a screen that has a button labelled "Startup/Shutdown." When I click that button, I am taken to a screen asking for Host credentials (OS account name and password) and database credentials (I use "SYS", the password I created, database is already filled in, and "SYSDBA" for "Connect as"). After entering this information, I click on OK. I get an error message at the top of the screen saying: "Couldnot contact the agent. Verify that the url for the agent is null." I looked up this string and a suggestion was to run " lsnrctl status"--I think (I've been trying a lot of things over the past couple of days to try to get this running) and the program replied that the environment variable "ORACLE_SID" wasn't set. I looked up what I was supposed to do and went into Windows 7 Environment area and set the value."
from your problem let's do it one by one:
to run lsnrctl, from windows desktop--> click start menu -> on search program and files box type cmd, the start menu will change its appearance and it will show you black icon with names cmd.exe do right click on that icon then choose run as administrator. It will open DOS command prompt for you.
on DOS prompt type : set ORACLE_SID=<your database name>, example : set ORACLE_SID=orcl then enter
now you can execute your lsnrctl status from the prompt.
in case you need to start listener you can use : lsnrctl start from previous DOS Prompt or you can start it via services.msc as follow : from windows desktop--> click start menu -> on search program and files box type services.msc then enter on window that open find oracle<oracle_home>TNS listener services then double click this services click on button start.
as for the agent problem is not running try to check the services with names oracleDBConsole<dbname> is it run or not.
hope it helps.
