parallel query server died unexpectedly - oracle

I'm running a SQL query, using Oracle sql developer, joining 4 tables on an AWS machine. Database is Oracle11g2.
Simple queries work fine but this specific query fails to run with the following error:
12805. 00000 - "parallel query server died unexpectedly"
*Cause: A parallel query server died unexpectedly, PMON cleaning
up the process.
*Action: Check your system for anomalies and reissue the statement.
If this error persists, contact Oracle Support Services.
See trace file for more details.
The error is vaguely described in search results and no concrete solution has worked. Would be great to get help with this one.

PowerBI Desktop: intermittent ORA-03113 errors

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.

DoCmd.OpenQuery("Actionable Query") "Property Not Found"

I have a code that executes DoCmd.OpenQuery Command and it that has been executing fine from last 3 years.
However, all of a sudden it has started failing with Error Message "Property Not Found". It randomly fails for anyone query from set of 5 queries. Further, it displays a message "Operation not allowed this time" if I try to execute the statement again.
These are Action Queries (Inserting data into SQL Server Linked Table),
within this query data is being inserted into SQL Server Linked table from SmartSheet Linked Table. I am surprised to see DoCmd.OpenQuery executes fine at one instance and fails at same statement at other instance. For your information I got the same error message when I tried to executed DoCmd.RunSQL.
Nothing has changed in ACCESS or in SQL Server.
E.g. Query
INSERT INTO dbo_SQL_Server_LinkedTable
SELECT Quarter,Site,Category, 'Commit',Comments
FROM Dbo_SmartSheet_LinkedTable;
Also, Just to mention that same set up works fine on Office 2016 32 bit. I cannot use this because Client Machine does not have Office 2016.
Thank you,

Oracle Outer Join cause ORA-12537: Network Session: End of file

I have Oracle 11.2.0 (x64) installed on my personal development environment. When running SQL selections that Left Join more than 10 tables I am easily to get Oracle crash with ORA-12537: Network Session: End of file. If I use Inner Join there is no such problem. For a same particular query this happens all the time, no matter how many data is in my database (in fact not much data is there, no more than several hundred rows.)
I work with around 100 people who install Oracle with same version and roughly same settings, and apparently not seen anywhere else as far as I know.
This error can be triggered no matter if I run the query from SQL Developer or using C#.Net Data Access.
Any ideas please?
My Alert/Log.Xml has these:
Exception [type: ACCESS_VIOLATION, UNABLE_TO_READ] [ADDR:0x45] [PC:0x35797B4, _kkqstcrf()+1342]
and
Errors in file c:\oracle\diag\rdbms\orcl1\orcl1\trace\orcl1_ora_1192.trc (incident=41028):

Oracle Connection Probelem: ORA-01034: ORA-27101

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.

ORA-03113 end of file communication

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.
