Got the following Article from Somewhere . I need to try it out though .

Any Concerns with using the Following Approach ?

CASE - What can be done to make export/import run faster?
> The IMP/EXP programs run in two task mode to protect the SGA from
> potential corruption by user programs. If you relink these programs in
> single task mode you can gain much improvement in speed (up to 30%).
> Although Oracle won't support this they supposedly use this method
> themselves.
> Although running in single-task is faster, it requires more memory
> since the Oracle executable's text is no longer shared between the
> front-end and background processes. Thus, if you need to transfer
> large amounts of data between databases, relink the executale for
> greater efficiency.
> cd $ORACLE_HOME/rdbms/lib
> make -f ins_rdbms.mk singletask
> # make -f ins_rdbms.mk expst
> # make -f ins_rdbms.mk impst
> # make -f ins_rdbms.mk sqlldrst
> # mv expst $ORACLE_HOME/bin/
> # mv impst $ORACLE_HOME/bin/
> # mv sqlldrst $ORACLE_HOME/bin/
> Now use expst and impst instead of imp or exp.
