Need help in installation of SQL Developer in Win7

Dear Frens,
I got a task to validate the SQL developer(64 bit version) in Win7 environment. I followed the advice in this form and installed the 64 bit JDK first.
It can be verified:
C:\>java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
Then SQL developer asked for the path of java.exe for the first time, and after configuring it to the correct path, I found it had problems creating the connection to the database when I tried to click database connection button. Please be noted, I do not have the win admin right for the PC.
The error messages are listed below. Need some help from you guys.

Need help with installation

I recently received a laptop from school to access my online classes. When I tried to use Adobe Reader I received the following message: Adobe Reader 9.1 has encountered a problem and needs to close. Sorry for the inconvenience. I tried tech support at school and was told to uninstall and reinstall the program. During the installation process I received the following error: Error 1321 The installer has insufficient privileges to modify the file C:/Program Files/Adobe/Reader 9.0/Reader/Onix32dll. I need this program for school. Can some one please help me.

Hello again, Michael,
Was unable to do the UAC changes. Buttons where not highlighted. I just went ahead and uninstalled Adobe and downloaded Foxitsoftware and it works. Thanks for all your help Michael you have made my online school experience better.
Sincerely,

Subject: Need help with installation
Hello again, Sherri:
It's my pleasure to provide assistance when I can :•) Having just recently graduated after 7 years of effort just to get a 2-year degree, I can relate to needing software to get class work accomplished. I will do everything I can to make it happen for you today.
Since you didn't mention, the UAC setting, I'd like you to disable it for me if it isn't already:
1. Open Control Panel
2. Under User Account and Family settings, click on the "Add or remove user account"
3. Click on any user account
4. Under the user account click on the "Go to the main User Account page" link.
5. Under "Make changes to your user account", click on the "Change security settings" link
6. In the "Turn on User Account Control (UAC) to make your computer more secure" click to unselect the "Use User Account Control (UAC) to help protect your computer". Click on the Ok button.
7. You will be prompted to reboot your computer - do so when ready
You may need to uninstall/reinstall Reader after the reboot in order for the problem to go away, but that part I am not certain of. Try to duplicate the issue prior to taking that step.
If you are unable to resolve issues with Adobe Reader, I recommend using a different reader that has much less bloat and is updated regularly:
http://www.foxitsoftware.com/pdf/reader/
FoxIT is a FREE alternative to using Adobe's Reader. Support for free Adobe products is limited forums such as this. The same holds true for open source alternatives except the manufacturer usually helps support their forums while Adobe doesn't monitor this forum or any like it. I know how important it is for you to focus on your classes so don't beat your head against a wall just because Reader won't work when a viable solution exists.
Best of success in your pursuit of knowledge!

Run the sapinst.exe with the port 21212.This port 21212 is the default port used during the installation of netweaver.

Hello world,
I´m absolutely new in the world of SAP and just started lessons in ABAP on Netweaver 7.02.
Our teacher told us to install a mini SAP at home for training, so I download this :

And this is my problem : I never installed a system like this before.
My Notebook have : 2.16 GHz, 8 GB RAM, 500 GB Harddisk
Did I need something else and how can I get it ?
How to start installation ?
Is there any installation guide ?
I'll be thankful for any advice.

Need help in writting the sql

The sql
select 'alter system kill session '||sid||','||serial#||';' from v$session where username= 'EV05';
give the output in the below given form
alter system kill session 69,38769;
But i need the output to be
alter system kill session '69,38769';
Can some one re-writes the sql select statment,
Thanks
Naveen

Naveen,
This isn't the forum for help with writing SQL - rather with using the SQL Developer product. In future, I would suggest that you use the SQL and PL/SQL forum for these sorts of questions.
However, to answer your question this time, you can include a ' in a string by having two together ie 'fred''s' will return the string fred's.
The following SQL will give you the result you want:
select 'alter system kill session '''||sid||','||serial#||''';' from v$session where username= 'EV05';

Need help in rewriting a sql query

Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.

If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:
Re: Oracle Third Party Tools and Oracle Database
Oracle have enough tools of its own to satisfy the various needs.

I just need help in the structuring wise. I can build the logic for inserting and updating inside. I want to know how i can continue to get for "inserting" and "deleting" as well.
you will understand my question better if you go through main code, present output and required output format below.
I know this is a bad design first of all. but the below code is a legacy one. so i cant change the entire structure of the code :-( all i can do is to continue designing it to add new changes. Hence sought help from you all.

Need Help with Formula using SQL maybe

I need help! I work with Crystal reports XI and usually manage just fine with the Formula editor but his one I think will require some SQL and I am not good at that.
We are running SQL 2000 I think (Enterprise Manager 8.0) Our sales people schedule activities and enter notes for customer accounts. Each is stored in a separate table. I need to find activities that are scheduled 240 days into the future and show the most recent note that goes with the account for which that activity is scheduled.
The two tables, Activities and History, share the an accountID field in common that links them to the correct customer account.   I want to look at dates in the Startdate.Activities field more than 240 days in the future and show the most recent note from the History table where the accountid's match. I figure my query will contain a join on AccountID.Activities and AccountID.History used with Max(completedate.History) but I do not understand how to word it.
I would like to perform all this in crystal if possible. I humbly request your help.
Membery

You SQL would look something like this...
SELECT
a.AccountID,
a.BlahBlahBlah, -- Any other fields you want from the Activities table
h.LastComment
FROM Activities AS a
LEFT OUTER JOIN History AS h ON a.AccountID = h.AccountID
WHERE (a.ActivityDate BETWEEN GetDate() AND DateAdd(dd, 240, GetDate()))
AND h.HistoryID IN (
     SELECT MAX(HistoryID)
     FROM History
     GROUP BY AccountID)
This method assumes that the History table has a HistoryID that increments up automatically each time a new comment is added... So a comment made today would always have a higher HistoryID that one made yesterday.
If I'm wrong and there is no HistoryID or the HistoryID doesn't increment in a chronological fashion, it can still be done but the code is a bit more complex.

Need help with min max sql

hi all, forgot i had a user name and password and haven't needed help for quite a bit since i didn't do sql for a while but now i'm back at reporting again...
Here is a sample table as i remember it:
Item     Date     Time     Time Frame     Duration     Duration Frame
A     20100926     0     5     500     10
A     20100926     600     10     500     30
A     20100926     1500     12     100     30
B     20100926     1800     28     200     40
B     20100926     2200     6     150     70
B     20100926     2600     15     600     60
B     20100926     3600     30     200     70
Results Set (expected):
Item     Date     Time     Total Duration
A     20100926     0     1600:20     --basically max (time+duration) - min(time+duration)
B     20100926     1800     2000:00
Sorry, but. I didnt put my sql statement as I wasn't planning on posting and left it at work, but, i've been looking on internet and people say to use min/max function and i've attenpted it with it works with just this table (without grouping). But as soon as i group it the values seem to mess up.
Last i remembered it gave me:
Item     Date     Time     Total Duration
A     20100926     0     1600:30     --basically max(time+duration) - min(time+duration)
B     20100926     1800     2000:70
I think it's looking at max duration which is 30&70 and hence it retrurns those values in the result set. Is it because of the max function hence it's returning this value? any help is appreciated. thanks

Need help for learning how to develop interfaces for Oracle R12 EBS

Hi all,
I need to learn how to create interfaces in PL/SQL for Oracle R12 EBS Financials. I cannot find a good starting point for the documentation and examples to help me get started in this area. Would appreciate tips
for this area.

Hi,
What kind of interfaces you are planning to develop?
Oracle already provides list of APIs that can be used (in R12, it is responsibility).
Oracle Integration Repository Documentation Resources Release 12 [ID 396116.1]
Oracle Integration Repository
http://irep.oracle.com/index.html
If those APIs do not satisfy your requirements, you can refer to "Oracle Applications Developer" guide as well as SQL-PL/SQL guides.
Applications Releases 11i and 12
http://www.oracle.com/technetwork/documentation/applications-167706.html

Need help in Report From SQL Query

Hi All,
I am facing a problem with a report. I need your help.
I am creating a Report From SQL Query (Portal) with some arguments passed at runtime. I am able to view the output, if the query returns few rows ( arount 1000 rows). But for some inputs it needs to generate >15000 records, at this point the page is getting time out (i think!) and showing error page. I am able to execute query from the SQL Plus console ot using TOAD editor. Here the query is not taking more that 2 mins time to show the result.
If i am executing from Portal i observed that, once i give the appropriate input and hit submit button a new oracle process is getting created for the query on UNIX (I am usign "TOP" command to check processes). The browser page will be shown error page after 5 minutes (i am assuming session time out!) , but on the backend the process will be executed for more than 30 mins.
I tried also increase the page time out in httpd.conf, but no use.
The data returned as a result of the query is sized more than 10 MB. Is caching this much data is possible by the browser page? is the returned data is creating any problem here.
Please help me to find appropriate reasone for the failure?

There could be a variety of reasons for the delayed processing of this report. That includes parameter settings for that page, cache settings, network configurations, etc.
- explore best optimization for your query;
- evaluate portal for best performance configuration; you may follow this note (Doc ID: *438794.1* ) for ideas;
- third: for that particular page carrying that report, you can use caching wisely. browser cache is neither decent for large files, nor practical. instead, explore the page cache settings that portal provides.
- also look for various log files (application.log and apache logs) if you are getting any warnings reflecting on some kind of processing halt.
- and last but not the least: if you happen to bring up a portal report with more than 10000 rows for display then think about the usage of the report. Evaluate whether that report is good/useful for anything?

Need Help in correcting the sql statement

H Experts,
I am not if I can post this query in this section, but as I am executing this statement on repository DB , I assumed to post here.
I have a requirement to calculate the database sizes from the tables in repository.
table 1 : MGMT$DB_TABLESPACES_ALL : has the information on all the tablespace information from each database. and it has information of all the databases.
table 2: MGMT$DB_REDOLOGS_ALL : has the information on all the redolog files information from each database. and it has information of all the databases.
Now to calculate the size of each database , we need to collect the sizes from both tables and then need to add.
below is the sql i prepared and sql didn't return and systax error , but the final output is completely wrong. Seems like its multiplying the data somewhere and getting the wrong information.
please help me in doing the required modifications.
