Connecting to a database on another machine, please help!!!!!!
Hi there,
I am new to oracle and at the minute I am using Oracle 9i. I have set up a database on one machine (PC2) and would like to create an odbc from another machine (PC1) to connect to this database. I have set up a listener for (PC1) the using oracle net manager on PC2. what I want to know is: is there anything else I need to do on the PC2 end???? Also, what needs to be done on the PC1 end??? please help!!!
If everything is setup and working properly on the Server PC2, you can just test the ODBC from PC1 (assum you already have an Oracle ODBC drive).

Connecting to a database from another computer...
hi guys!
i just wonder if there is a simple way to connect to my database from another computer?
do you have to change something in this method?
private static Connection getConnection() { Connection con = null; try { Class.forName("com.mysql.jdbc.Driver"); String url = "jdbc:mysql://localhost/Movies"; String user = "root"; String pw = "x"; con = DriverManager.getConnection(url, user, pw); System.out.println("****Connected****"); } catch (ClassNotFoundException e) { System.out.println(e.getMessage()); System.out.println("1"); System.exit(0); } catch (SQLException e) { System.out.println(e.getMessage()); System.out.println("2"); System.exit(0); } return con; }
thanks! :)

Problem in recovering a database on another machine
Dear All,
I need your help in restoring and recovering a database on another machine. I don't have access to old machine to get logfile or archivelogs. I have taken full backup using RMAN. I have restored the database using rman sucessfully and trying to recover the database. RMAN have't restored the logfile. Database version is 8.1.7.4, OS is Solaris 8. In recovery, its showing the problem in rbs file. I'm showing all command and error. Just give me any idea that how to recover it sucessfully.
SVRMGRL>recover database using backup controlfile until cancel;
ORA-0279: Change 1935345519 generated at 08/19/2005 16:45:50 needed for thread 1

ORA-01194: file 2 needs more recovery to be consistent
ORA-01110: data file 2: '/u06/oracle/oradata/PROD/rbs01-PROD.dbf'
This RBS file size is 7GB. Is it the reason of problem. Even I tried until time, but its also has same error.
SVRMGRL>recover database using backup controlfile until time '2005-08-16:20:10:00';

ORA-01194: file 2 needs more recovery to be consistent
ORA-01110: data file 2: '/u06/oracle/oradata/PROD/rbs01-PROD.dbf'
Why its asking for archive file which generated on 19th, when I'm trying to recover until 16th only.
Regards
RakeshHi.
What is the size of the redo logs in the database. With a small amount of transactions, there might be redo in this particular archived file from two days back. The timestamp of the archivelogfiles does not indicate that all redo in the file is from this day. It might have changes several days back if no logswitch occured inbetween.
So, if I were you, I would provide all archivelogs required to get the datafiles consistent.
As a matter of fact, if archived redo is in the following folder :
/u07/oraexp/PROD/arch/
I would use recover database until time and press return for all archived logs svrmgrl comes up with.
I assume that the database was closed normally prior to taking the offline backup.
Good luck.

Database Link question ! Please help me ....
Hi everybody,
I have some question about database link.
For example, I have 3 database, database 1 and database 2 connect together by database link db_link1, database 2 and database 3 connect together by database link db_link2.
I want to ask: Can I connect from database 1 to database 3 ? ( Of course don't use database link between database 1 and 3, just use database db_link1 and db_link2 )
Both db_link1 and db_link2 are public database link.
Can I restrict user access by 2 these public database link ?
Thanks a lot.A database link has directionality-- it connects from one database to another database. It is not a bi-directional link.
Assuming db_link1 exists in database 1 and connects to database 2 and db_link2 exists in database 2 and connects to database 3, it should be possible to read data that is in database 3 from database 1 without creating a new database link. But you'd need some sort of intermediate layer in database 2 (i.e. a view in database 2 that queries an object in database 3) because you can't nest database links in a single SQL statement. Of course, you would almost never actually do this for a variety of reasons. The only time I've ever heard of someone using this sort of setup is if database 1 is a very recent version of Oracle and database 3 is a very very old version of Oracle such that a database link between 1 and 3 is not possible.
If you create a public database link, you cannot restrict access to that link short of potentially doing something with VPD. If you're creating a database link using a fixed username & password that would create a security issue, it would make far more sense to create private database links.

Could you please help me?Hello!
Using a cradle with the Tungsten E2? Tried bypassing the cradle and just use the hotsync cable? Tried a different computer yet? Somehow, the PC is having problems getting a signal from the device. I assume you have the laptop charger plugged into the laptop during this? Not going through a docking station or port-replicator.
One crazy thing you can try is unplug the charger from your laptop, remove the battery from the laptop and leave it out for like 10mins and put it back in and reboot the laptop. This should not cause side effects but still contact your OEM to make sure that nothing else is needed after leaving the battery out for extended period of time. Keep me posted.

I have photoshop elements 11 installed on my desktop pc, I want to install it on my laptop as well, I read that it can be installed on two systems, but I get a message taht the redemption code has been used by another ID, please help
A redemption code can only be redeemed once. It is used to acquire a serial number. The serial number is what you need to activate the installed software. If you did not keep the serial number when you first installed, you might still be able to find it in your Adobe account online if you registered the software.

I upgraded to iOS 7 yesterday on my iphone and now none of my apps shows me any new message and when i open the apps it says "Connect to itunes for push notifications". Please help!!!
Same here. I don't know how to solve the problem, but I figured out a way to close the app without re-starting or resetting the phone. If you click ok and then press the home button twice really fast before the dialog box shows back up, you can put the phone in multi-tasking mode and close the app without having the shut the phone off or reset it. Anxiously awaiting the fix for this since I have several apps I use that I can access at the moment.

Hi Kellyssi,
Thanks for visiting Apple Support Communities.
If you're being asked repeatedly to check terms and conditions, try restarting and then resetting your iPhone:
