Wrong filename of Archive Log files

Hello

I'm performing an Disaster Recovery test of my SAP/ORACLE DB.

In step 8 - Apply Archive log files, I have the problem that the system does not see my archive log files.

The reason is  that the brrestore is looking for files:

1_6739_879248014.DBF

My archive logs but are named:

SIDARCH1_6739_879248014.DBF

If I rename the archive files to 1_... (without SIDARCH), brrestore finds them.

I copied the init<SID>.ora from source system.

The parameters are correctly set:

*.log_archive_dest_1='LOCATION=F:\oracle\P01\oraarch\SIDARCH'

*.log_archive_format='%t_%s_%r.dbf'

Why is brrestore looking for the wrong file name?

Thanks and regards

Marco
