Database version: 11.1.6.0 OS: OEL V4 RAC database Hi, I have a FRA ASM disk group that at times is reported as containing corrupt header information, so I want to remove all of the files in it, drop it and then re-create it. My problem is how best to make copies of the files and then put them back. As this is the FRA diskgroup this involves a controlfile, online redo log files and archive log files. I have played a bit with the ASM cp command, found that "cp -r" does not work, "cp" does but that is going to be hard to use with the archive logs. So I figured I could use rman instead to take copies of the archive log files, but I have not tried that yet. So I moved on to the controlfiles, creating a copy using the "cp" command, but when I tried to copy it back I get this: ASMCMD> cp /tmp/oracle/control02.ctl +ORCL_FR_AREA/S3tsps/CONTROLFILE/control02.ctl source /tmp/oracle/control02.ctl target +ORCL_FR_AREA/S3tsps/CONTROLFILE/control02.ctl ASMCMD-08012: can not determine file type for file->'/tmp/oracle/control02.ctl' ORA-15056: additional error message ORA-19762: invalid file type DGGetFileAttr20 ORA-06512: at "SYS.X$DBMS_DISKGROUP", line 207 ORA-06512: at line 3 (DBD ERROR: OCIStmtExecute) Googling for this I found that others have tried and failed with the same thing, so cp is not good if all I can do is create a copy of the files but then I cannot copy them back! I thought that this would be easy and that the asmcmd cp command would be the way to easily create copies of at least the control and online redo log files. Any advise on what other options I have here, is dbms_file_transfer a better bet? Thanks Pete -- //www.freelists.org/webpage/oracle-l
