Hi,
I'm testing a disk failure scenario. I had the redo logs multiplexed over three locations (Windows drive letters); one of the three locations also contained the data files. I blanked out the Windows drive that contained the data files and went through a recovery using RMAN. All is well except that the redo log members that were located on the blanked Windows drive are of course still missing; the database opens and so forth but puts messages like this in the ALERT.log:
ORA-00321: log 2 of thread 1, cannot update log file header
ORA-00312: online log 2 thread 1: 'F:\APP\NGORA12CR2SRV\ORADATA\ORATEST5\ONLINELOG\O1_MF_2_BW4B5MY0_.LOG'
What is the "right" way to replace the missing members? Do I simply create all new redo log groups with new members on all three disks? Do I carefully copy the LOG files representing the missing members from one of the other locations? Do I add new members in that location and drop the existing (missing) members?
Does it matter?
thanks!
Martin
