Hi, all:
could you please kindly help me to ******** the following concepts about Oracle Export/Import:
1. "Oracle Export can be done while the exported DB is open.
Therefore, Oracle Export can be used as an alternative On-line Hot backup"
Is this correct??
2. When using Oracle Export to export the "Full DB", instead of export to one big .dmp file,
how can we export to several smaller .dmp files with the same size (ex:1GB each)??
3. " in a DB with inconsistant Database files, we can export the entire DB and then import it back. Oracle will then see these Database files as consistant"
Is this true?? and how come after export and import Oracle will treat them as consistant??

thank you very very much for your help!!
