Export From Oracle11g Database And Import Into Oracle9i Database Fails With Core Dump (Doc ID 1154215.1)

Last updated on NOVEMBER 06, 2012

Applies to:

Oracle Server - Enterprise Edition - Version 11.2.0.1.0 and later
Information in this document applies to any platform.

Symptoms

When trying to complete an export/import from Oracle11g database to Oracle9i database, for example, during a downgrade, there have been reports that the import process fails to complete.

The behavior reported several times is that the import process will just terminate and no completion messages are generated to neither the import.log file or to the screen.

At times a core file is also generated.

Following is an example of what the screen output may show when exporting from the Oracle11g:

-- export
#> exp crmproj2/crmproj2@psq02 tables=PS_PT_MBNK_CSTSVC file=PS_PT_MBNK_CSTSVC.dmp log=exp.log

Now the output generated during import. You can see imp just appears to die and the message Memory fault(coredump) is appended to the output:

#> imp system fromuser=crmproj2 touser=crmproj3 file=PS_PT_MBNK_CSTSVC.dmp ignore=y log=imp.log
