Ora 03114 нет связи с oracle
Знаете ли вы какую-либо причину, чтобы получить следующую ошибку, когда я беру несколько отчетов Oracle?
"FRM-40735: триггер ON-ERROR вызвал необработанное исключение ORA-03114"
Это случается несколько раз для нескольких пользователей.
ORA-03114: not connected to ORACLE — ошибка с несколькими возможными причинами. Как предполагается, это означает, что ваш клиент (формы в этом случае) был отключен от базы данных.
Не понимаю в чем дело, понятного объяснения не нашел.
В PL/SQL Developer при попытке открыть процедуру или пакет (пишем имя в SQL окно и кликаем с зажатым Ctrl) падает эта ошибка.

Эта ошибка возникает, если соединение с серверным процессом оборвалось. Самая частая причина — серверный процесс завершился ненормально. Причин этого ненормального завершения может быть очень-очень много и тут без анализа лог-файлов не обойтись.
Узнать, куда серверный процесс пишет логи можно так:
По-умолчанию примерно такое:
Серверный процес обычно не пишет логи (только самые критические ошибки). Включить логгирование можно так:
Ошибку как в вопросе я воспроизвести конечно же не могу, но как примерно искать причину подобных ошибок см. далее.
Запускаю сессию с любого клиента и нахожу к нему серверный процесс, в моём случае:
Предлагаю ему закрыться (провоцирую ошибку):
В клиенте получаю ошибку, что соединения больше нет:

The reason is likely there is a DBA who
- doesn't read documentation
- doesn't use online resources
- can only be bothered to post questions like 'My car doesn't work, please fix my car' without doing any troubleshooting himself and without providing any details.
Your request must be considered insulting and rude.
Senior Oracle DBA
I have read the online info and tried some troubleshooting. But could not get the reason for this issue. The listener log looks good and no error on alertlog about the timed out.
That is the reason I requested here to know if anyone has faced similar issue.
I am not insulting anyone here or being rude with anyone.
The last time i faced this issue it was because the session was disconnected by the DBA(read: Myself).
Probably you can check truss on your listener.
Also it would be helpful to check what entries exist in the alert log before this error is encountered.
User tried to login at 7:50, after 3 failed attempts the user got logged in, listener.log shows connection details at 7:54
- There are no erros in listener.log
01-OCT-2013 07:46:58 * service_update * abc * 0
01-OCT-2013 07:54:00 * (CONNECT_DATA=(SERVICE_NAME=ABC)(CID=(PROGRAM=D:\Apa?Software?Foundation\Tom\bin\tom**5.exe)(HOST=CM*****APP)(USER=SYSTEM))) * (ADDRESS=(PROTOCOL=tcp)(HOST=app server ip)(PORT=57279)) * establish * ABC * 0
01-OCT-2013 07:54:02 * service_update * abc * 0
- No erros in the alter log.
The listener only reports requests that it receives. If a connection request has a network timeout before the request gets to the listener, it will not - it cannot - be reported in the listener log.
Your reported error code (ora-03114) seems to indicate a possibility that the app is either issuing sql statements before it ever gets connected, or the established connection is getting dropped. Either way, I wouldn't expect to find much about it in the listener log. The listener only handles the request to get connected to the database. Once that connection is made, the listener is completely out of the picture. You can even stop the listener and it will have no effect on established connections.
ORA-03114 occurs when an oracle call is made, when no connection is established.
You have said before that user's login through an application, if the application is user writen, you have to check the program. Might be some problems between the program and database.
Thanks for the explanation. What you said is true.
Is anything to do with the database idle ? because the user who tried to login first in the day he is only facing the issue, after that everything going smooth without any issue.
Based on information that listener.log has no error at all I presume the request is not even reaching listener in the first 3 attempts.
Logically thinking the issue is with some firewall, router etc going to sleep state as this issue is only faced by the person trying to login for the first time.
you can check the expire time for various factors involved.
I'm sorry i can't be of much help right now. When you do find out the solution please post it on this forum.
We have recently migrated app/db to new windows machine. Before that everything was working fine. No changes made to app/db expect migration to new servers.
Firewalls are disabled on new servers.

whether or not above is/was true is moot.
Existing configuration does not know or care about what may or may not have occurred or existed in the past.
You must deal with the present & now errors exist.
I suggest that deploy packet sniffing software to see at the lowest level what occurs when error get thrown.
Oracle programs or not, it is safe to say that every user of a computer in the past twenty years has faced the frustration of attempting to initiate a program to have it halted by a problem with network connectivity. The very potential of computer technology in the 20 th and 21 st centuries has hinged thus far on the ability to connect to a network of other users and servers, so, invariably, issues will occur in the quest of working this out. These types of problems are particularly pertinent when the success of a database system relies on its accessibility to several users at various locations within a company. The ORA-03114 is one of many Oracle error messages that are prompted when these type of connectivity issues are present.
The Problem
The ORA-03114 is an error message triggered when a user attempts a call to Oracle when no connection was established. This will typically happen in response to a user-written program not being logged on. In many cases, the server or listener process may not be running or another location shut down the database while trying to access.
This error message can also happen due to communication trouble caused by a disconnection from the database. This can derive from problems with connection pooling such as shared servers or multi-threaded server. There can also be some problems with missing entries to the tnsnames.ora.
The Solution
The ORA-03114 can occur because of a number of different problems. As with many Oracle errors that have numerous possible triggers, the first user step is looking at the log to see if anything seems out of character. Let’s go through a few different scenarios that a user might find after searching the log.
In some cases, a user will be prompted to enter a password in the middle of creating a database. Despite entering the correct password, the user is unable to connect. So, what’s the problem? Typically in a situation such as this, the database is held up in the EMCA step (Enterprise Manager Configuration Assistant). When configuring a database using EMCA, the database will be temporarily unavailable and users will not be able to connect. The listener will need a new tna connection, but it does not have access to the new database yet. The best way to prevent this issue is, prior to the creation of the database, modifying the SID_LIST section of the listener.ora and adding an entry to the yet-to-be-formed database, then reloading – this will establish a connection for the listener.
In another scenario, the database server remains idle for a certain interval of time, triggering a router of firewall to disconnect the server. What can be done in response? Verify the configuration by setting the database to send a packet every ten minutes to offset the firewall settings. Use the parameter SQLNET.EXPIRE_TIME to specify the time interval. It will default to ‘0’, but it is recommended to adjust this field to ‘10’. To run a test, stop your Oracle database instance, edit the SQLNET.EXPIRE_TIME, restart the database, do a full connect to the Oracle driver as SYSTEM/MANAGER and execute the stored sleep procedure in Oracle. Adjust the expire time as is necessary for your system requirements. You can also check the EMCA, select your database and click down to “security\profile\\idle time” and set the time that the system can remain idle before disconnecting to your preferences.
Looking forward
These are just a few of the primary prompts for the ORA-03114 error. These corrections should provide the user with plenty of tactics to take the problem on. However, there is a vast assortment of issues that can prompt an ORA-03114, as in far too many to list. Fortunately, the aforementioned solutions can successfully correct a number of variations of the error. In the event that you need further assistance, you should contact a licensed Oracle database consultant who can work further with your company to prevent these types of errors.
