I am connecting to oracle 12 in Oracle cloud, from PowerBI Desktop windows server 2016.
Oracle client is installed and TNS file configured.
Oracle is hosted by a vendor so my only access is to directly query the database.
In powerBI, when using an oracle connection, i get ORA-03113 errors about 50% of the time when refreshing data. There is no discernible pattern to the appearance of the error.
If i connect via a System ODBC connection set up in windows, I dont get any issues or errors, although the data load is a bit slower.
I would appreciate ideas on what may be causing this issue or what to check to help get more information.
I'm afraid your issue needs some deeper analysis as ORA-03113 might have various reasons, but typically it means that the 'oracle' executable has terminated unexpectedly once there was an existing connection. You should try to isolate the SQL command that is executing when the error occurs. It can be done either by checking the trace files on the server or by using SQL*Net trace if you don't have access to the server. If a statement can be isolated which consistently raises the ORA-3113 error, then it can be further analysed (like execution plan, triggers, etc), or maybe the best to raise an SR so Oracle Support can work on the issue. If you have access to Oracle Support you can find more information about ORA-03113 troubleshooting in MOS Doc ID 1506805.1. Let me know if I can help you any further.

i have an error which is driving me crazy and i dont know how to deal with it. In a PC with windows 10 64-bit , i got an oracle database server 11g. Everytime the pc restarts or shuts down and then restarts i get the following error when i try to connect to the database :
ORA-01033: ORACLE initialization or shutdown in progress
Process ID: 0
Session ID: 0 Serial number: 0
the only way to get my database running is the following one:
open a cmd and type :
rman target /
recover database;
shutdown immediate;
startup mount;
alter database open resetlogs;
after that everything is fine , but if i restart the PC i get the same error again.
Has anyone dealted with anything like this before?
I have checked the hard disk and is ok, have defragmented it, have run test diagnostics, it is driving me crazy. Any idea would be welcome!
Thanx in advance!
That is a pretty general error. Your database can have issues with either starting up or maybe shuting down cleanly.
I would recommend you looking at the end of the alert.log file right after the server is started, before performing rman recovery.
You can find hints there as why the database did not started up to open state, where and why it is hanging, etc.
EDIT: So the error is ORA-00600 [dbkif_find_next_record_1]
Whenever an ORA-00600, or ORA-00700 or ORA-07445 occurs, this is an internal error within Oracle core. For this cases there is this neat tool at http://support.oracle.com which can search the knowledge base of Oracle MySupport network and try to find existing articles and/or patches, hotfixes for respective arguments of these internal errors.
The tool can be found as Oracle Support Doc ID 153788.1.
Unfortunatelly, the lookup tool did not found anything for argument ORA-00600 [dbkif_find_next_record_1]. In that case please make sure that your OS is updated and supported. Also if you are running on VM, that the VM has all parameters set according to Oracle's recommendations and if there is nothing suspicious there, you will have to open "Service request" at http://support.oracle.com
I am new to Oracle database in general, but I'm attempting to get Oracle's SQL Developer running on a workstation that has pre-configured System DSNs created for an OracleRDB database. I've confirmed the ODBC connections are working because I can use MS Access to connect and link to the tables. The "test" options within ODBC also succeed. Now I am trying to get a similar connection created using SQL Developer so I can see the column types and write queries in a more useful editor.
Here's what I have available when examining the ODBC connection properties:
Now I'm trying to create a duplicate connection in SQL Developer, but I'm at a loss for why things don't work. I first tried using the default SQL Developer installation, but couldn't get things working. Then I discovered there's an OracleRDB extension available, so I installed that, but I keep getting this error when attempting to use similar values:
As I stated, these ODBC connections were pre-configured on the workstation I'm using, so I don't know anything more than what is provided by the Oracle ODBC driver window.
Is there something obvious I'm not seeing or doing to replicate this connection in SQL Developer? Or perhaps something else I can do to debug this to learn more?
UPDATE
On the advice of one answer I'm trying to make the connection with JDBC, but having a hard time understanding what I'm doing wrong. Here's another screenshot with the connection parameters I have available, but with the server and database names changed:
With these values (the port came from my tnsnames.ora file), if I try to make a JDBC connection I keep getting the following error from SQL Developer:
One final attempt I did was to use the proper values in the Oracle RDB tab, and when I use them and click 'test' the Testing Connection dialog just spins and never seems to return:
So I apologize for the long post here, but I'm struggling because there's just something I am really not understanding about how this all works. I appreciate everyone who took the time to read this question.
Oracle SQL Developer is a Java Application. You'll need to get the JDBC Driver for RDB.
Once you have that, in the SQL Developer preferences, find the Third Party JDBC section, and then use that to add an entry and point to the JAR for what you just installed.
Step by step instructions here.
Working connection string for RDB Thin Driver:
RDB_DB_CONN_STR = "jdbc:rdbThin://node.myplace.com:1707/";
where node.myplace.com is the name of the OpenVMS node hosting the RDB Thin Driver, 1707 is the port number assigned to the RDB Thin Driver.
The oracle was working properly on the server but suddenly from 2 days ago I've not been able to connect it, unfortunately the server manager is not around for weeks and I am not familiar with oracle very much, I appreciate your help in advance.
The error:
An error was encountered performing the requested operation:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
01034. 00000 - "ORACLE not available"
*Cause: Oracle was not started up. Possible causes include the following
- The SGA requires more space than was allocated for it.
- The operating-system variable pointing to the instance is
improperly defined.
*Action: Refer to accompanying messages for possible causes and correct
the problem mentioned in the other messages.
If Oracle has been initialized, then on some operating systems,
verify that Oracle was linked correctly. See the platform
specific Oracle documentation.
Vendor code 1034
The database has been stopped deliberately or it has crashed. No way to tell without consulting the alert log and any trace files which might have been generated.
This is not the sort of thing which can be talked through on SO. It requires genuine expertise, If you haven't got a DBA or anybody with power user access to the server you're out of luck.
Does this database matter? I'm tempted to say "obviously not", because who would leave a critical business process untended for "weeks"? However, if you really need this database you'll have to tell your boss they'll have to spring for an emergency DBA.
I am running a long query(having lot of subqueries) with rownum from VB6 which is giving ORA-03113 end of file on communication after approximately 1 minute. The query run fine from Toad. When the same query is run from VB6 without ROWNUM then query works fine. Also this is parameterised query, if i remove parameters and enter the values directly in query, then also query run fines from vb6.
This query was running fine few days back. Now it is not.
I tried increasing the connection timeout but still i am getting error after 1 minute. Could anyone suggest what could be the problem?
This often indicates that an ORA-00600 internal error has been thrown on the server. Check the alert log and trace files.
ORA-03113 on the client side is one of the oracle catch-all error that is thrown. You need to see if there is any additional error that accompany that error to give you an idea of the problem. The problem can be server side if there is an ORA-00600 that accompanies the ORA-03113 with the same sid/serial of the session. Check the server logs for both the ORA-03113 and any addition error. If there are no server side error, then the error is client side. Check for any network/connection related issue, but since the query works without the rownum network is probably not the cause. That means its probably a client side bug, now comes the need to enable client side tracing of the connection and see if you can generate a consistent issue and trace that you can then use to raise a case with oracle support to see if there is a bug you can get patch/fixed on the client.
My team inherited an Oracle-based web application and they are fairly inexperienced with Oracle database servers.
The Oracle 10g server is running on a Windows 2003 Server with plenty of disk space and from time to time, all connectivity is lost, the application stops working, not even SQL Plus is able to connect to the database server.
But when we check the Windows Service manager, it says that the service is up and running. A restart usually fixes the problem, but we need to properly troubleshoot it so we know what's causing it and so we can avoid it to happen anymore.
Where should we start looking for clues? What are the criticial log files we should be investigating?
On the server you should have an environment variable called ORACLE_HOME which indicate the root of the Oracle install. Most likely the Oracle trace/dump folders will be under there. Search for a folder called "bdump" (background dump). That's where the main log file, knows as the alert log, will be, as well as trace files generated by background processes. There will be an adjacent file called "udump" which will contain any trace files generated by user processes.
However, my real advice is that you should either hire someone who knows Oracle or get Oracle Support involved.
The alert log would be the first file to check.
It will probably be in $ORACLE_HOME/admin/bdump and (probably) called alert_DATABASE-SID.log
It contains most of the important actions that the database does, as well as any important errors that occur.
I have to agree with cagcowboy. Check your alert logs for errors. If no errors then maintain a sysdba login into the database and when it hangs, attempt to do a hang analysis. See metalink note 215858.1 on hanganalyze.
Have you tried tnsping? We've occasionally run into problems with the listener that requires an assist from our DBA. tnsping is the diagnostic tool we use to do triage.
I would recommend hiring an experienced Oracle DBA if at all possible.
check the alert log to see how the Db is structured. sometimes badly set parameters make hangs or slow performance. or you can shutdown and start in mount mode, then check the v$parameter values for problems. setting total memory is very important.
