Hi

I am doing successful exports and imports cycle between my office and home PC with the help of guidence i got from my following topic at orafaq.

http://www.orafaq.com/forum/t/77391/67166/


Now as my DBA side is very weak, so i want to know the drawbacks of these import/export cycles if i use it on daily basis.
Your expert opinion is required.

Thanks.

Export and Impoort is meant for moving data around.
As long as your volume stays low and your are not treating exported dumps as primary backup, you just fine.

So I guess you are truncating all tables before import? You might want to specify consistent export (parameter). Some datatypes don't do well during export/import (blob). Also some home grown functions, procedures, and views may become invalid. Just recompile them.
Mahesh Rajendran is correct. You are moving the entire database each day. And don't pretend this is your backup strategy.

Finding and recompiling invalid objects? Run catproc.sql in the $ORACLE_HOME/rdbms ?? directory. I would still check your home grown functions and procedures and recompile them manually.
