Oracle idle time

Hi all,
In one of our test database(11.2.0.1.0),we want to disable idle time out for developers.
There resource_limit=true and default profile has been assigned to all users,where idle time is unlimited.
Also SQLNET.EXPIRE_TIME=0.
But still the session gets ORA-03113 error, if the session has been idle for long time.
We want the session not to be disconnected.
By default,is Oracle following any idle time out limits.
Need your help

You may have issues that are not linked to timeout. Please check your database instance alert log:
$ oerr ora 3113
03113, 00000, "end-of-file on communication channel"
// *Cause: The connection between Client and Server process was broken.
// *Action: There was a communication error that requires further investigation.
//          First, check for network problems and review the SQL*Net setup.
//          Also, look in the alert.log file for any errors. Finally, test to
//          see whether the server process is dead and whether a trace file
//          was generated at failure time.

Oracle Idle Time errors

Any suggestions on how I can avoid "ORA-02396: exceeded maximum idle time, please connect again" errors?
Getting rid of the idle time restriction on the database is not an option, so I was looking for a parameter to tweak so Pages recovers better from Oracle idle timeouts.
What's happening are javascript errors and other errors in the logs when there is a timeout.

Idle time for Oracle user

Hi,
we have PS FSCM9 with Oracle DB 10g R2. For the moment idle time for Default profile of Oracle users in DB is UNLIMITED. I wonder if I change it to 90 Minutes (in order to have less memory usage for idle sessions) there would be a probleme for PeopleSoft ERP ?
Thanks before.

It could be an issue since Peoplesoft is working through Application server and connection pool. It could stopped (or killed) application server connection client, which you would avoid to be able to reconnect later on with other front end user.

How to track clients idle time and force to Login View

How can I force clients to the Login View after a period of idle time ( 1 hour). My mobile application consist of many views and need the time out to work from any view. Your assistance is appreciated.Using Flash Builder 4.5 and AS 3.0.
I was able to make it work using FlexEvent.Idle to determine the inactivity. But it only works when I am on the second view, if I go deeper (third view) it fails. Here is the code I am using and the error I get

Report Server does not respond after certain idle time

We have an oracle 10g application server on solaris 10.
The report server has the defaul settings for time out , callback etc..
After the report server stays idle for 2 or 3 hours and the first report that comes after that takes around 8 to 10 minutes to generate. The report server engine does not seem to be getting active immediately.
Is there any parameter I can change so that the reports do not get effected.
Thanks

I have put the idle time out at 300 minutes and the max idle time as 350 minutes. But that does not seem to have helped.And also I have min engine as 1 , max as 10.
Even with the above settings , When the report engine is idle after 30 minutes the 1st report to generate after 30 minutes takes 9 minutes.
please let me know if there are any other parameters I need to change.
thanks

CLOSED: MAPVIEWER LONG PREPARATION TIME AFTER LONG IDLE TIME

SR # 6896831.994
Customer: NEDGRAPHICS BV
Mapviewer Release: 9.0.4
This issue was posted to the Field Service Forum. They responded with
For Map, we do create the datasource and related maps, themes, styles to be used for Map. The exeuction part is done by Mapviewer and we don't have much control on the mapviewer code on performance tuning point of view.
Please post this question in mapviewer forum
Issue:
After MapViewer being idle for some time (+/- 60 minutes) it takes a long time to generate the first map image --> 5 minutes.
In the MapViewer logfile with log-level=finest, I see that there is a very long preparation time.
After producing the first map image the next (same!) image is produced very fast.
What could be the reason?
What does MapViewer do during "preparation"?
Customer statement:
I am a very experienced Oracle specialist and a very experienced MapViewer developer.
Could you please pass on my request to the MapViewer developers?
I have to know what is going on during preparation time.
Is there a possibility to get more detailed logging of the preparation time?

Additional customer info.
UPDATE from customer
================
The first time after long idle time it takes between 100 and 300 seconds.
After that it takes less than 2 seconds.
Can it be a dabase connection issue?
Will it make a difference if I use a database connection via data-sources.xml
instead of a direct data-source in mapviewerConfig.xml?
This is what I mean :
Method 1:
<map_data_source name="NBG"
jdbc_host="plutonium"

RESPONSE from customer
====================
The database is restarted once a day in the morning. That could explain the problems in the morning. But there are also problems during day time after some hours of idle time when the database in not restarted.
After testing we noticed that we don't have the problem if we use database connection through OC4J (data-sources.xml).
If we use that method every database connection is cleaned up if it is not used for 15 seconds or so.
If we use the other method (database connection in mapviewerconfig.xml) then the database connection is open for a long time and then we have the problem with the long preparation time.
This problem only occurs in a DMZ environment. MapViewer is installed on a DMZ server and connects through the firewall with a intranet database.
Is it possible that the firewall software prevents communication of an open database connection after a long period of idle time?

Native SQL from ABAP - ORA 02396 max idle time exceeded

Hello,
I am trying to read a table outside of the R/3 environment using native SQL statements. I'm getting the data just fine. But every other time (depending on elapsed time), I get the ORA-02396 exceeded maximum idle time, connect again. Here's the SQL code I'm using and I'm obviously not getting disconnected but I'm not sure why. Any help?
Open a native SQL connection.
EXEC SQL.
    connect to 'ONECD'
ENDEXEC.
Retrieve information from the BVER tables.
EXEC SQL PERFORMING read_dental.
    select emp_ssn_num, emp_fname, emp_lname,
           to_char(start_date, 'YYYYMMDD') as start_date,
           rec_type,
           to_char(eff_date, 'YYYYMMDD') as eff_date,
           vendor_plan_id
        into :dental
        from opr$8oc.BVER_CURR_DENTAL_MASTER
ENDEXEC.
EXEC SQL PERFORMING read_medical.
    select emp_ssn_num, emp_fname, emp_lname, rec_type,
           to_char(start_date, 'YYYYMMDD') as start_date,
           to_char(eff_date, 'YYYYMMDD') as eff_date,
           network_code, pcp_number, patient_flag,
           vendor_plan_id,
           to_char(network_eff_date, 'YYYYMMDD') as

         into :medical
         from opr$8oc.BVER_CURR_MEDICAL_MASTER
ENDEXEC.
Disconnect from the native SQL connection.
EXEC SQL.
    DISCONNECT 'ONECD'
ENDEXEC.
The system log has messages like 'Work process is in reconnect status' and 'Work process has left reconnect status' after the ORA-02396 message. And I specifically do a disconnect at the end and a connect at the beginning, but it looks like it is trying to do a reconnect?
Thanks,
Diane

Hi Daine,
Oracle Parameter IDLE_TIME set by the administrator.
1. Since you are using Secondary database
   connection, the connection must
   have been made with the help of BASIS Team.
2. This secondary database ORACLE
   has some settings/parameters
   which have been set to say 10 minutes, 60 minutes etc.
   , so what happens,
   if there is NO ACTIVITY / NO SQL / NO INTERACTION
   with the database ,
   the connection is IDLE
   and hence ORACLE then disconnects by itself.
3. Contact your basis team / oracle administarotr
team to INCREASE this setting.
(they do it for some security purpose, firewall etc)
I hope it helps.
Regards,
Amit M.

Capture system print event and system idle time

Hello,
We are creating a desktop widget using AIR. The widget will be docked to the system tray. What we want to achieve is:
1. When the user invokes Print function at the OS level, from any location/appolication, the AIR widget shall listen to it and show an alert.
2. The widget should be able to detect a predefined system idle time (wherein the user is not interacting with the system as a whole - neither mouse nor keyboard inputs - for a predefined interval), and perform an action based on that.
How shall it be possible to detect the above 2 scenarios in AIR?
Any help in this regards, will be highly appreciated.
Thanks in advance.
Warm Regards,
Parag

Customize Session Idle Time

I need to set Page Idle Time out to 1hr i.e. 3600 sec. so that session gets expire and user gets logout after 3600 sec. if the user remains idle.
Please help me in finding out from where can I set this value ?

Hi,
You can set this in WebGate profile. By default the idle session timeout value in WebGate is 3600 seconds. If you are using custom application with Oracle Access Manager for SSO and if you are configuring idle timeout in your application, then you need to modify it accordingly.

Oracle idle sessions

Hi Gurus,
I need to learn more about Oracle idle sessions, why/how they are created and why some of the idle sessions does not terminate easily.
Is there any ways to determine which SQLs are responsible for idle sessions. Also SQL way to identify and destroy idle sessions.
Does this make sense.
Thanks
Amitava.

First, why do you believe that idle sessions are a problem?
A session is IDLE if it is not, at the instant you query the data dictionary, executing a SQL statement. Most sessions will be idle most of the time because most of the time your applications are waiting on humans to do something or spending time processing data in the application. Just because a session is idle now is no reason to believe that it won't be ACTIVE shortly.
A modern three-tier application will generally create a pool of connections to the database on each middle tier server. Generally, those pools will be sized for at least reasonably busy conditions. If you happen to look at the database when the application isn't particularly busy, you're likely to see a bunch of idle sessions. That's not a problem. While you could force the application server admins to decrease the size of their connection pools, that may negatively affect the performance of the applications and introduce extra load on the database server for no real benefit.

To check client idle time

Hello friends
My enviroment is Oracle 8. I have 2 oracle users.
On these 2 users approx 150 clients are feeding data.
I want help in the following :-
1. If machine is idle for 10 minutes, it should be
logged out and this information is inserted in a table.
Idle means no keyboard/mouse operations. But if it
is a backgroud process, Report generation or Form
process, it will continue.
Thanks in advance.

thanks. But it was not helpful. as i said that I have only
two users and the users are accessed by morethan 150 session
(application user). The profile will restrict only user. I am not sure it will also check for sessions. I want to check idle time of these clients users. I mean to say if the machine using the users is idle for more than 10 minutes then it should logout from the forms and its entry should go to a table. I think it will clear my problem to you.
thanks and waiting
You can use profile to do it:
create profile user_prof limit idle_time 10;
alter user <username> profile user_prof;
Then create a trigger:
create or replace trigger trg$blo
before logoff on database
begin
insert into <table_name>
values (user, sysdate);
end trg$blo;

Jdbc connection lost after idle time

Dear users,
i'm using the oracle 10g database. Now i found out that several programs (SQuirreL, QuantumDB,...) which use the ojdbc14 driver are losing connection to the database after about one hour idle time, but it is not set in db configuration to disconnect (eg parameter idle_time is not set). What could be the cause of this? Is this a error of jdbc (the java exception is something like socket lost) or is it a missconfiguration of the db?
Thx for help.

With a simple java program that makes a select on a database table over jdbc after one Hour idle_time this exception happens: (the program is started local on the database server so no firewall or router is between)
java.sql.SQLException: No more data to read from socket
