Moving redo logs on physical standby database to ASM

Hi,

                 My customer is attempting to move the redo logs on his physical standby database from raw devices to ASM – he hopes to achieve this by dropping the current redo logs on the standby database one by one, in each case replacing it with one created on ASM. He is following note 740675.1, which describes the tasks of dropping redo logs from, and adding redo logs to, a standby database. However, a problem arose at step 5 (attempting to drop the online redo log group) – error ORA-01624 – was encountered. The note suggests that if this error is seen, step 4 (to clear the online redo log group) had been skipped – however this was not the case, step 4 was executed correctly (although we did note that the status of the redo log group in question remained at ‘CLEARING’). Several attempts were made to proceed beyond this point, without success.
