I am trying to clone a V8.1.7 DB to a different system running V10.2 Below is the output from RMAN: ================================================= RMAN-03022: compiling command: restore RMAN-03022: compiling command: IRESTORE RMAN-03023: executing command: IRESTORE RMAN-08016: channel aux1: starting datafile backupset restore RMAN-08502: set_count=13 set_stamp=533064604 creation_time=01-AUG-04 RMAN-08089: channel aux1: specifying datafile(s) to restore from backup set RMAN-08523: restoring datafile 00001 to /u01/oradata/dbx1/system01.dbf RMAN-08523: restoring datafile 00002 to /u01/oradata/dbx1/rbs01.dbf RMAN-08523: restoring datafile 00004 to /u01/oradata/dbx1/tools01.dbf RMAN-08523: restoring datafile 00007 to /u02/oradata/dbx1/security_data01.dbf RMAN-10030: RPC call appears to have failed to start on channel aux1 RMAN-10036: RPC call ok on channel aux1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure during compilation of command RMAN-03013: command type: Duplicate Db RMAN-03015: error occurred in stored script Memory Script RMAN-03002: failure during compilation of command RMAN-03013: command type: restore RMAN-03006: non-retryable error occurred during execution of command: IRESTORE RMAN-07004: unhandled exception during command execution on channel aux1 RMAN-10032: unhandled exception during execution of job step 1: ORA-04062: signature of package "SYS.X$DBMS_BACKUP_RESTORE" has been changed ORA-06512: at line 144 RMAN-10035: exception raised in RPC: ORA-04062: signature of package " SYS.X$DBMS_BACKUP_RESTORE" has been changed RMAN-10031: ORA-4062 occurred during call to DBMS_BACKUP_RESTORE.RESTOREBACKUPPIECE Recovery Manager complete. ================================================================== I'm using the following command file. connect auxiliary sys/password@aux1 run { allocate auxiliary channel aux1 type disk; duplicate target database to dbx1 nofilenamecheck; } exit ================================================= What am I doing wrong & what needs to be changed to allow the cloned DB to actually get created? FWIW - I never see any new datafiles on the 10g system for this instance. I am keeping the SID the same & the directory structure is identical. Any assistance would be greatly appreciate TIA!
