How to increase duration of timeout session in SQL-developer.

Hi masters,
I am using the Oracle tool SQLdeveloper 3.1.07.
Its automatically disconnecting from server after every 5-10 minutes idle time.
Please suggest me how to change settings to not to disconnect from server.
Thanks in advance.

SQL Developer doesn't have a timeout - any timeout you are experiencing will be set at the database level or possibly in a firewall.
You can try to use a 'keepalive' as discussed in Can I run a periodic query to keep Orcale SQL Developer connection alive? thread.

How to prolong the bluetooth timeout session on ipad and iphone

how to prolong the bluetooth timeout session on ipad and iphone?
I understannd that the standard timeout setting is 3 mins. what if I want to prolong the connection duration, how should I do?

To my knowledge, there is no "time out" on a device. A mouse, KB, etc will go into a low power mode after a short period of non-use.

How to open a package body in Oracle sql developer

How to open a package body in Oracle sql developer..any shortcut for that

I need another way to get to my package body. I'm on a locked down system, so the only way I can reference anything is if I already know the name of it. I accidentally overwrote my text document that I was using to work on it and I closed out of the package body in sqldeveloper. There must be a command, like an alter or some such. Anyone know the old fashioned way of looking at a package?

How to increase the request timeout value in Oracle 10g web container

Hi,
Iam using Oracle10g Application server .
For long running backend process my JSP page is getting re-submitted after 3 mins.
How do i avoid this ?
Is there a way to increase the http request timeout interval.
If so where do i change the timeout interval.
In IIS web server I can change the timeout interval.
Thanks
Sridhar.

Hi,
If you mean to increase the request timeout i.e the time when a request is submitted to the server and the response is sent by the server it can be done in httpd.conf file located in $OracleHome/Apache/Apache/conf directory.
The attribute to be used for setting timeout is "Timeout". By default teh value is 600 seconds i.e 5 minutes.
After making these changes , run command dcmctl updateConfig -ct OHS and restart the HTTP Server. Please note these commands need to be run only if the httpd.conf changes are done through text editor.
Hope this helps.

ok, but how i found the listener o the tsnames, because i searching in all disk (c) but i dont found them, or how i can turn on the listener o whe is the directory when i put the files, because the installation dont have the /network/adm for put the files
Edited by: user13373417 on 07-Jul-2010 09:06It appears you don't have a very clear understanding of how the client and the server are configured to communicate with one another.
============
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

How i can deal with DB schema in SQL developer ?

Hi
Thank you for reading my post , how i can make sql developer just to show one schema ?
Thanks

What the Natalka wanted to say is so that the
hardwired user does not visualize none another user
when clicar in the option 'Other Users'.
For this, you must clicar with the right button of
mouse on the option 'Other Users', 'Apply Filter' and
to move for the panel of the left all the users who
you do not want that they are visualized.
It is not this what you want? If possible, detail
more its request.
Remembering that each user in the Oracle is
corresponding to one schema.by the way, how can I create tables in sql developer if I don't see the one I have already created thanks

I have had found that the following works sometimes when coming immediately after the create or replace package body in a script (although it isn't doing anything for me on invalid package bodies at the moment):
show errors package body <package name>
Because it is inconsistent, you cannot really trust it, which gets you back to Jim's options (open in editor or compile from connection tree) or the old long hand of
select * from user_errors where type = 'PACKAGE BODY' and name = '<package name>'

How to view changes using SVN plugin for SQL developer

Hi,
We recently moved to SVN. I have checked out the PL/SQL code from the SVN server to my local C Drive. But after I have made changes to couple of PL/SQL files, I am not able to figure out how to see my changes and compare with the checked out version (for example, like we have CVS diff option). I searched through the options but could not find any suitable option.
Can someone point or help how to do this ?
I want to check my changes before committing to the main trunk
Thanks,
Ravi

In your window where you edit queries, right above the window, below the tab, next to a tab that says "SQL Worksheet" there is a tab that says "History"; click that, see diff(s). See here: http://duncandavies.files.wordpress.com/2009/02/sqldeveloperhistorytab.jpg?w=460&h=257

How to abort a running process in Oracle SQL Developer?

Is there a keystroke combination I can use? Thanks!

I had a problem earlier today when I was running some code with > 50,000 lines and it kept on bringing up the "Enter substitution variable" box, which would not allow me to click anything else and once I clicked cancel I didn't have enough time to get to the red x before the next box appeared. Although this happened a bunch of times eventually there was enough time for me to get to the red x and change the code, but that's why I was wondering if they was a keystroke combination.
