max_dump_file_size parameter should restrict the size of the dump file. HTH - Mayen "Ozgur Ozdemircili" <ozgur.ozdemircili@xxxxxxxxx> Sent by: oracle-l-bounce@xxxxxxxxxxxxx May 11 2010 11:25 AM Please respond to ozgur.ozdemircili@xxxxxxxxx To ORACLE-L <oracle-l@xxxxxxxxxxxxx> cc Subject 2,2 GB Coredump Hi, Did anyone had the problem of Oracle creating dump files of 2+ GB? We are dealing with ORA-07445 and ORA-04030 today. For the 3rd time all the nodes create dump files of 2.2/2.1 Gb which fills up the space. Is there any way to stop Oracle creating coredumps temporarily? Any ideas on how to solve this until we find the main cause? Thanks.
