I used dd to clone a x4100 server with Linux Red Hat. The hardware is identical for old and new servers. Then I changed IP address and host name. The newly restored server is up and running but Oracle gives following errors and cannot start.
(...) Opening oracle. ALTER DATABASE OPEN * ERROR at line 1: ORA-01113: file 1 needs media recovery ORA-01110: data file 1: '/../../system01.dbf'
Trying to log into SQL*Plus....
ORA-01033: ORACLE initialization or shutdown in progress
If I run
recover datafile '/../../system01.dbf'; I get
ORA-00283: recovery session canceled due to errors ORA-00322: log 3 of thread 1 is not current copy ORA-00312: online log 3 thread 1: /../../_REDO3A.log
How can I fix the problem? What is the wrong thing in restoring the Oracle with dd?
