Oracle Error Message
RMAN-05534: WARNING: LOG_FILE_NAME_CONVERT resulted in invalid ASM names; names changed to disk group only.
Reason for the Error
It was not possible to convert ASM Oracle Managed Files names using LOG_FILE_NAME_CONVERT parameter. RMAN changed these invalid names to the converted disk group name instead.
Solution
If the automatic change is incorrect, use one of the following options instead of using LOG_FILE_NAME_CONVERT for ASM Oracle Managed Files: 1) Use the LOGFILE clause for online log files. 2) After DUPLICATE completes, create standby log files using the SQL ALTER DATABASE ADD STANDBY LOGFILE command.
