 Hi all,

  I have been used 11gR1 64 bit on linux.

  I read some documents about data block corrupt ! I also made some test cases for this problem and fix it with DBMS_REPAIR or RMAN (REPAIR WITH NOPROMPT or BLOCKRECOVER...). This test cases, I did success. But I also have some problems that need some helps.
 
  1. Assume that I have table TEST, and there are alot of users are operating (like select, insert, update,...) on it. Suddenly, there is a block corrupt --> Can I repair it while transactions still operate on this table? how I can select some transactions are operating on it ? 

Howdy, Stranger!
