Out of memory using ora2pg

[Prestation3.EXPLOITATION@xxxxxxxxxx]

Hi,


I try to migrate an Oracle database 9.2.0.5 ( one schema)
to an Postgresql (8.1.3) database.
I use ora2pg to do this ...

When I use it after a while I get the following error:

       MONTANTTVARECUP => type:NUMBER , length:22, precision:, scale:, 
nullable:Y , default:
        DTCREA => type:DATE , length:7, precision:, scale:, nullable:Y ,

ERROR:  out of memory

Is it a problem with perl memory or posgresql memory ?
Can you hellp me please ?

Thanks in advance ...
