Have you logged a call with Oracle support? There are many causes of 7445's and oracle supports web site has a handy set of documents about them. Also they have:- : Troubleshoot an ORA-600 or ORA-7445 Error Using the Error Lookup Tool. I would highly recomend talking to them.

ORA-07445: exception encountered: core dump [hshget1()+199] [ACCESS_VIOLATION] [ADDR:0x18] [PC:0x8C4341F] [UNABLE_TO_READ] []

Hello all,
I am working on windows 64 bit (local system, testing)
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
my database was working just fine, I was copying export dump(exp/imp) from 'A' hard disk(external) to 'B', as it was urgent I gave a table for import(imp) from 'A' hard disk which had the original dump.
import of table stopped with ORA-03113: end-of-file on communication channel
i thought it might be because I gave import when copy was going on, later on when copy was over I gave the same table for import, this time also I got same error.
when I tried to login as user "test" is gives me ORA 01033 error.
Enter user-name: test/test
ERROR:

To add more I was studying/practicing "Auditing in Oracle", yesterday System table space was getting full hence, exported "IDL_UB1$" and truncated it.
Please let me know if I need to provide any more information, also help me out to solve this issue.

Yes I have the backup of truncated table with me(I am practicing "auditing" in my local system hence exported the table and truncated the table as system table space was getting full.)
also i checked the trace file c:\app\administrator\diag\rdbms\prod\prod\incident\incdir_94924\prod_mmon_7848_i94924.trc, but not sure what to check..i mean it gives the same

not sure how to read this trace file,i mean how to find error part, kindly let me know on this.

I got this error and i raised a SR in metalink, and metalink suggest to make
"_complex_view_merging" = false, but its already set to false.
So what to do for this resolution of this error.

When you already have an open SR, you should ask Oracle support for further assistance.

Any ideas on this, read something about a bug using links, not sure though.

ORA-07445: exception encountered: core dump [ldxsti+0208] [SIGSEGV] [Addres

Hi,
I am continuously getting this error in alert in my Production database.
Please suggest on how to get rid of this.

See ORA-7445 Troubleshooting

Have you observed an ORA-07445 error reported in your alert log?
While the ORA-600 error is "captured" as a handled exception in the Oracle source code, the ORA-7445 is an unhandled exception error due to an OS exception which should result in the creation of a core file. An ORA-7445 is a generic error, and can occur from anywhere in the Oracle code. The precise location of the error is identified by the core file and/or trace file it produces.

And see this advice from Oracle ACE Billy Verreynne
Re: ORA-07445: exception encountered: core dump

Refer to Metalink (now called My Oracle Support ) note id 310099.1 - it lists a whole bunch of 10r2 bugs related to the EVAOPN2 module.
Also, SOP for such errors is to log a SR (Service Request) with Oracle Support.

And many links indicating problems when either the DB or the OS is migrated from 32 bit to 64 bit
