Datapump export has become the defacto export tool on Oracle 10g (exp has been deprecated). I was using oracle10gR1 and expdp run successfully and placed the dump file in three different location. - Set the degree of parallelism to two times the number of CPUs, then tune from there. Exporting Oracle database faster with parallel option is an excelent feature of oracle Datapump. Unlike exp/imp where the entire export job is done by the client tool which has initiated the export, expdp/impdp initiates the process but the entire job is done at the database level where the user connects to using the expdp/impdp tool and thereafter you can also exit from the expdp. Dumpfile Compression Options As part of the Advanced Compression option, you can specify the COMPRESSION_ALGORITHM parameter to determine the level of compression of the export dumpfile. then again calculated size using query.

Scan listeners register the database services via IPC/TCP through pmon and Local listeners registers both the database and ASM instances via IPC/TCP through pmon. Data Pump compression is fully inline on the import side as well, so there is no need to uncompress a dumpfile before importing it. Data Pump is a server-side utility, meaning the dump file is written to (and read from) a directory on the database server. 4# Expdp/Impdp operate on a group of files called a dump file set rather than on a single sequential dump file. Right now I'm battling an unbelievably slow export but imports seem unreasonably slow as well. Hi - Even though we are changing the parallelism to any number , the job does not pick up the parallel , because worker parallelism remains the same ,Do you know how can we change worker parallelism ? You can see below I changed the parallelism to 16 but still in the insert query the parallel is 1. ORACLE 11G EXPDP AND IMPDP FEATURE. When Oracle Data Pump hit the streets, there was a veritable gold mine of opportunities to play with the new toy. The dump file set can be imported only by the Data Pump Import utility.
