If the directory changes, you need to create another control file to modify pfile.(4) create a service: Run oradim-New-Sid gbicc in cmd to create a service. The SID is gbicc. This step is not required in Linux.(5): Set up a listener: Net configuration assintant. (We recommend that you copy the files in the network of the source system and modify them according t
Run the DBV command to check whether the data file contains bad blocks before recovery.

You can view the data file number and block number of the bad data block to perform a full table scan on the table, for example:
Select count (*) from tablename;

Therefore, the data recovery center in North Asia has specially developed a program to verify the forward and backward offsets of the vhd format for matching.
