Sql developer hangs when saving pl/sql external package or package body fil

When I open a package body file I can modify the contents of the file.
Compilation of the file works fine but when I want to close or save the file SQL developer hangs. I use version 1.2 (previous version did have the same problem.)
Somebody has an idee what I'am doing wrong?

Are you using 1.2.1.32.13?

SQL*Plus hangs when connecting to remote DB (Solaris, 10gR2)

First of all the particulars:
Local System:
Solaris 8, Oracle 10.2.0.4, October CPU
Remote System:
Solaris 10, Oracle 10.2.0.4, July CPU
We are trying to initiate a connection from our local system to our remote system using a DB Link. After opening SQL*Plus, we log in with <user>@<dblink>, are asked for a password, and after entering the password, SQL Plus hangs indefinitely (we typically have to kill the sqlplus process to regain our session). Also, logging into the local system with a local account, and then querying using the db link (select * from dual@<link>) gives the same result.
From the remote system, we CAN log into the local system using the same process, and we can also query the local system. in other words, it works in one direction, but not the other.
We have checked all the usual suspects: tnsnames, sqlnet, db_domain, global_names, and all are set correct for our setup (although I of course welcome suggestions to check something else in the files). Also have confirmed validity of /etc/hosts entries, and permissions on those files for the 'oracle' user. A 'tnsping' and 'ping' are both successful in both directions, though I understand these only check the listener and hardware layer.
Our Sys Admin has checked firewall connections between the two systems, and stated that they're open on the listener port (1521).
Listener log files on the remote host, when the hang happens, show an established connection from the local host.
Does anyone have any suggestions as to what to check for next?
Thank you in advance for the assist!

Whew, that truss output is enough to make your eyes bleed!
This system is on a closed network, so I cannot post the files here, nor would I wish reading those things on anyone nice enough to spend a minute here helping me out!@
But comparing the truss from the "broken" system, and the working one, the sqlplus that hangs returns a:
ERR #134 ENOTCONN on a getpeernam() thread.
The other truss (working side), does not throw that particular line, and the truss output varies widely after that line in the output fille.
After a few moments letting the sqlplus process "hang", I get:
ERR #62 ETIME
Outside of that, lust a lot of hex values!

SQL Developer hangs when expanding table node

Hello All,
One of my schemas has 3035 tables. When I expand the "Other Users" node, then the schema owner, then expand "Tables", SQL Developer hangs. I have allowed it to run (as it indicates it is working) for 45 minutes, but it never returns.
I have one user with nearly the same behavior, but theirs returns after waiting 5 minutes.
Any ideas?

SQL developer hangs on Win XP if not admin user

Hi, I just installed Oracle 11g on Win XP sp2, as admin user.
Things appear working, except for SQL Developer which runs fine only when logging in to XP as administrator.
If I log in as a normal user, then SQL Developer hangs forever just after being started up, eating 50% of CPU. Task manager is required to stop it.
A few more details: it hangs just after asking about file name associations, showing on the left panel the connection I did while being admin.
SQL Plus runs just fine in any case.
If I run the alternative version (sqldeveloper.exe), the involved window reports:
WARNING: Unknown directive: SetSkipJ2SDKCheck
Using oracle.home=C:\oracle\app\Admin\product\11.1.0\db_1\sqldeveloper
Using ide.user.dir=null

javax.management.InstanceAlreadyExistsException: com.oracle.jdbc:type=diagnosability,name=main11.0
at com.sun.jmx.mbeanserver.RepositorySupport.addMBean(RepositorySupport.java:452)
then the ide windows hangs as reported above.
Any help is appreciated.

- sqldev is slower - and yes my machine is fast
- sqldev needs a mouse; the keyboard shortcuts are severely lacking
- output window is separated from SQL window
- It doesn't show me anything I couldn't get to before by typing commands & using TextPad
As far as sqlplusw.exe vs sqlplus.exe, I won't get into that discussion- all I'll say is that the "workarounds" on the Internet have not addressed my concerns. (control-c exits by accident, having to edit every shortcut on every computer/server I touch which either needs admin elevation or shortcut copy/paste or both, etc)
Either way- thanks again to sperkmandl for the solution (running sqldev as non-administrative user)! I never run on my machine as local admin; I only elevate when needed.

SQL Developer Hangs when connecting for Remote Debug

Hello,
I've been trying to use the Remote Debug feature of SQL Developer. We are writing a Web Application that connects to Oracle and I would like to debug a package function on the database server (which is not the same machine as my SQL Developer client).
To test my configuration, I tried connecting on SQLPlus creating a connection (by calling exec dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); ) and calling a function which had a breakpoint and the debugging started immediately on SQL Developer. Then I tried putting the dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); call inside the stored procedure I was debugging (prior to the line with the breakpoint) and it connected and got to the breakpoint successfully as well. So I'm pretty sure my firewall / user privileges are set up correctly.
So I modified the function that my web application eventually calls to create the connection (in order to remain in the same session) but whenever it gets to the connect_tcp line SQL Developer hangs and I'm unable to debug. I've realized that it only hangs if I have a breakpoint there. If I don't have a breakpoint then it creates a connection just fine. Of course without a breakpoint it's a bit difficult to debug isn't it? :)
My Sql Developer version is 3.0 and I'm connecting to Oracle 11.1.0 Below you can find a dump when running SqlDeveloper with console. My OS is windows XP and my Oracle instance is running on Linux.
I appreciate any help you can provide.

What I mean is that I put the connect_tcp command inside the package function I want to debug in order to ensure it's going to remain in the same session. e.g.:
Function GetValue Return Varchar2 Is
Begin
dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', '25255');
return 'My Value';
End;
I'm afraid I cannot post our code which causes this problem due to our information security policies and simple console and web applications failed to replicate the problem. The function creates a connection to Oracle SQL Developer (which can be seen in the environment with the small ladybug icon) if no breakpoints are set which obviously doesn't allow breaking into the function. However if a breakpoint is also specified in the Return line the connection seems to freeze Oracle SQL Developer. No ladybug icon is shown and no Remote Debug Session seems to open.

[4.0] Production SQL Developer hangs when attempting to expand Java in the Connection Navigator

Folks,
I'm running production SQL Developer on Oracle Linux 5.8 and whenever I click the Java link in the Connections Navigator with a SYS AS SYSDBA connection SQL Developer hangs.
Oracle Enterprise Edition 11.2.0.1.0
SQLDeveloper 4.0.0.13.80
Oracle Linux 6
JDK Version 1.7.0_45
Doing the same thing with user SCOTT (no SYSDBA) works fine (although there are not any Java objects).
Thanks,
Rich

This has been logged as a bug.
The bad plan/performance has been logged as a bug. SQL Developer didn't hang for me - I was able to cancel the query using the Task Progress panel.

SQL Developer hangs periodically

Hi,
I'm connecting to my test instance (Oracle XE) and each 5mins-10mins SQL Developer hangs. It doesn't matter what I'm doing, I can be executing a big query or I wasn't doing anything for a while and then simply consulting Columns of a table and hangs...
I saw the underlying error is:
oracle.javatools.util.CanceledException
     at oracle.dbtools.raptor.utils.Connections.getConnection(Connections.java:568)
     at oracle.dbtools.raptor.utils.DBObject.getConnection(DBObject.java:323)
     at oracle.dbtools.raptor.utils.DBObject.getConnection(DBObject.java:435)
     at oracle.dbtools.raptor.oviewer.base.ViewerEditorAddin.getEditorWeight(...
What may I check?
Any help will be appreciated.

Sql loader hangs

Hi All,
I have a java program which runs sql loader in a timer. That is the sql loader is used to load some tables with the data contained in a flat file. And I want this to be run every night.
I am using Runtime class to initiate a process which will invoke the sql loader. This works fine when I directly call my function in main.
But since I want this to run every night, I decided to invoke it thru the timer class. And when I do that the sql loader hangs and I have to terminate the process manually.
Is there any solution for the above problem?
Any help will be appreciated.
Regards,
Chitra

Just to give a lil bit more added clarity on the issue.
The requirement is like this. I have a flat file which needs to be uploaded to a database periodically. Every 24hrs. Now I am using Oracles SQL Loader to upload the data flat file. I am calling SQL loader from with a java program using Runtime class. Now I initiated this using a standard Java application and put it in the main class. It works fine. Now since I needed to have this running every 24hrs I used a Timer class to set the timer and to have it running evry 24 hrs. Now if I execute the same class above within the timer class, the SQL loader pops up in a new window and the program does not complete the execution. It just hangs. Which requires for me to terminate the process manually. All the data in the flat file is uploaded to the database but that is shown only after the proecess is treminated. Is there any solution for this ? Or does anyone have any idea as to why this is happenin ?
heres the code that I have written.
public class RmsDataLoader
Toolkit toolkit;
Timer timer;
public RmsDataLoader()
toolkit = Toolkit.getDefaultToolkit();
timer = new Timer();
timer.schedule(new RMSJobThread(),
0, //initial delay
24*60*60*1000); //subsequent rate
public static void main(String[] args)
RmsDataLoader rms = new RmsDataLoader();
class RMSJobThread extends TimerTask
public RMSJobThread()
public void run()
RMSJob rmsjob = new RMSJob();
rmsjob.runJob();
and the function in runJob is
public void runJob (String errorlog) {
try {
// Validation 1 : The datafile exists and the file size is not 0
String strDataFile = "W:\\rms_amps\\" + todayDate + "\\inv_company_label.dat";
File dataFile = new File(strDataFile);
if(!dataFile.exists()){
rmsExp.createLog(filename, filename, " Data File does not exist", todayDate);
} else {
long len = dataFile.length();
if (len <= 0) {
rmsExp.createLog(filename, filename, " File size is 0 ", todayDate);
// End of Validation 1
// create a process to invoke sql loader
Process process = Runtime.getRuntime().exec("sqlldr USERID=scott@umidb/tiger CONTROL=load_company_label.ctl LOG=load_company_label.log BAD=inv_company_label.bad DATA=inv_company_label.dat");
return ;
} catch (Exception ei) {
rmsExp.createLog(filename, filename, ei.getMessage() , todayDate);
ei.printStackTrace();
System.out.println (" Error while initiating the data loading " );
return ;

SQL Developer hangs for a few minutes after being idle for a while.

Is anyone aware of any issues with SQL Developer hanging for several minutes after being idle for several hours? After being idle for several hours (and probably minimized), when we bring up SQL Developer we just get a blank white window for several minutes before it becomes functional. Obviously, this isn't a critical issue, but sure is annoying when you run into it.
Thanks in advance!!
Rob

This is fairly typical java application behaviour. For whatever reason, they are particularly prone to being swapped out by the operating system and take time to swap back in.
There is an add-in around called "keepresident" which helps this but I thought it had been superceded in later JDK version.

Calling a remote procedure with db link - SQL Plus hangs

I am trying to call a procedure from a remote database with a db link, within a local procedure. The purpose of the calling the procedure is to get the server time from that database. When I try to compile this procedure on the local database SQL Plus hangs without giving any error message, I have to close SQL Plus. Below are my two procedures:
Local procedure:
CREATE OR REPLACE PROCEDURE get_server_time(p_remotetime IN OUT VARCHAR2)
IS
/*Grabs the system time from remote database .
l_remotetime varchar2(16) ;
BEGIN
get_remote_time(l_remotetime);
p_remotetime := l_remotetime;
END ;
Remote procedure:
CREATE OR REPLACE PROCEDURE get_remote_time(p_remotetime in out VARCHAR2)
IS
/* Grabs the system time from remote database and returns it to the
calling proc.
l_remotetime varchar2(16) ;
BEGIN
SELECT to_char(sysdate,'YYYYMMDDHH24MISS')
INTO l_remotetime
FROM dual ;
p_remotetime := l_remotetime ;
END ;
I personaly do not see anything unusall with the two procedures, but cant figure out what is making SQL*Plus hang.
Any help would be much appreciated.
Thanks In Advance

Hello
Are you able to run the procedure connected to the livetolocal database directly? It looks as if you either have a missing table or the permisions for the user associated with the database link are not sufficient.
As for calling the procedure, it would probably be more managable if you created a public synonym for it to hide the actual location. That way if you want to change the name of the DB link, or where it points to, no-one has to change their code, you just have to change the synonym.

SQL*PLUS Hangs when I have the Listener running?

HI,
I have Oracle 8i Personal Edition running on Win 98. I am using the default starter database (Global Name: oracle, SID orcl).
If I connect via SQL*Plus with the listener running i.e. connect scott/tiger@oracle, and then try to compile or call a stored produre SQL*Plus hangs. If I connect without the listener running i.e. connect scott/tiger everything works fine.
Does anyone have any ideas why this is happening?
Thanks in advance
Mark

try posting your code here, that way we might be able to help you more.

I checked the v$session_wait while it is hanging,
It is waiting for table s_evt_act (prod. 1.6 crores,dev. 1 crore)
In development it is accessing S_EVT_ACT_M8 (SINGLE COLUMN)index,in production
it is accessing S_EVT_ACT_F14(COMBN. TWO COLUMNS BUT DIFFERENT FROM PRODUCTION).
Thanks,
kumar.

Sql Developer hangs/ crashes while debugging

While happily debugging a piece of an SQL package using the remote debugger, I get a hang/crash on SQL devleoper. This occurs when I highlight a piece of code in the debugging window. The application freezes and has to be restarted using WindowsTaskManager.
Is this a reported bug? I was not able to find any discussion on the OTN forums or a quick google.
Regards,
Bill

RWB status 'delivering' and SQL process hangs

I am sending an IDOC to SQL Server thro XI using JDBC adapter. I am triggering a stored procedure to update SQL tables. The RWB status says 'delivering', sxmb_moni says 'successful' and all the steps are success in audit log. The status 'delivering' is not changing to sucessful.
When i look at SQL-server side, the process is in sleeping mode. I have verified the stored procedure and it was executed sucessfully. After the COMMIT TRAN, RETURN(0) statments, the process is going to 'sleeping' mode. The @@trancount is 2. If I double click the process, the sql statement is 'IF @@TRANCOUNT > 0 COMMIT TRAN'. This process hangs at this step and it is not accepting the next message. If I kill the process, the stored procedure is executed once and its going to sleep mode and not returning the status to XI to make the flow complete or to change the status to successful.
Thanks.

HI Shankar ,
Its seems that there might be some problem in your srored procedure.Did u tried to use some other stored procedure.I assume that you have uploaded the right version of driver for SQL server you are using.Remember JDBC adapter is vendor and version dependent.
You can also look at the JDBC : FAQ at service market place.
Thanx & Regards
Vinod

SQL Developer hangs after each query

I have a strange situation that just started. After every query, SQL Developer 3.0.02 just hangs for about 20 seconds and then returns to normal. The times displayed for the query completion are correct - it's just the UI freeze. I am running under Vista against a 10R2 database. All was working fine since 1/13/11 until last Friday. Running with the included JDK.
Any idea what changed?

This could be related to a problem with SQL History. If you have SQL History open, it can slow things down drastically.
