Tanel, Thanks for your input and clarification. It is a development database so no archivelog an d norman either . Those blocks were having a table RESOURCE_CONSUMER_GROUP$ table. After dropping and recreating it from other database, logical problem has gone. Besides database started up clean now without error message in alert_sid.log. I may now ignore dbv error.

Influx doesn't mean corrupt, you are dbv'ing an online file? In 9i, when dbverify finds a block that is inconsistent, it reads it again - if the block has changed, then dbv determines this block as in flux (being written at same time dbv reads it). Dbverify probably retries a few times to try to get the consistent image before marking the block as influx. To which segment do those blocks belong to? Perhaps AUD$ or FGA_LOG$? > Should I restore it from cold backup to get rid off this error? If you got RMAN backups you could do block level recovery for your corrupt block if you don't have much downtime allowance. If you do, then just restore the file from backup, then verify whether the restored file is ok with dbv, if it is then shutdown, replace the file, recover and open up your db again.
