ORA-03113 error when using Oracle 9i with Mapx 5.0

Question

Hello,
I am using Personal Oracle 9i Release 2 with Mapx5.0 on Delphi.
Accessing the layers using tab files also as server layers..,
and commonly using the method of Mapx Layer.SearchAtPoint
Search is done on region, line as well as on point objects...,
at some point of time it flashes me the error
ORA-03113 end-of-file on communication channel
I am not exactly able to figure out when it gives..,
but i m getting it after some clicks on the layers
The same executable is working fine with Oracle 8.1.7
As anybody faced such a problem and knows the possible cause
Thanks,
Binoy

There is some java bug that is causing some problems if you are using 9.2.0.3. Here is some information:
Workaround for bug 2755842:
Event 10499 can be set (any non-zero level) to revert to the old behaviour.
==================================================
Setting the EVENT 10499
=======================
Check if the database server is using a server parameter (spfile) a parameter (init.ora) file.
From sqlplus, connect as sysdba and execute the command:
show parameters spfile
If the value is NULL or empty, then spfile is NOT enabled and init.ora is used.
1) If SPFILE is used:
SQL> show parameters spfile
NAME TYPE VALUE
spfile string
%ORACLE_HOME%\DATABASE\SPFILE%ORACLE_SID%.ORA
a) Using sqlplus logon as sysdba
b) Execute: alter system set event="10499 trace name context forever,level 4" scope=spfile
sid='*';
c) shutdown
d) startup the database
2) If INIT.ORA is used:
a) In the init<SID>.ora file, add the parameter event="10499 trace name context forever,level 4"
b) Stop and start the database
Hope this is it.
