Oracle Database Discussions

Hi All,

Very good afternoon to all you guys, need a small help from you people. I have few question regarding the Standard Edition and Enterprise Edition, which i have given below please help me.

1. Do we have any system through which the features of enterprise edition, can be managed in the standard edition with an alternate workaround.(say for eg. Dataguard, rebuilding the indexes, block level recovery, rman incremental backup is it possible or not and compressed rman is possible, will expdp run in standard edition and what about the parallel argument is possible) . can these features will be possible via. unix scripting

2. In Standard edition, is it possible to buy plugins the features we use for enterprise edition

3. What are the risk involved while downgrading the database, the database is in enterprise edition and need to downguard to standard edition.

Thanks in advance, please reply me soon since i have to report to my customer and i hope you people would know these thing better.

Regard
