Hi,

 

I have below system

 

 

NW 731 SPS08 JAVA on Oracle 11

 

 

 

I was trying to perform a export of JAVA system using SWPM and It is failing due to below error

 

 

 

ORA-01578: ORACLE data block corrupted (file # 5, block # 214

 

 

data file 5: 'G:\ORACLE\SID\SAPDATA4\SR3DB_2\SR3DB.DATA2'

 

 

 

I have run dbv on the file and belwo is the output.There are many continuous segment corrupted on that file.

 

 

dbv file=G:\ORACLESID\SAPDATA4\SR3DB_2\SR3DB.DATA2 blocksize=8192

 

 

DBVERIFY - Verification complete

I have an offline backup of Nov 14 and DB is in archive log mode.After that there are many changes in the DB made.

 

How can I fix this issue.

 

 

Thanks,

Mofizur
