This issue is observed in windows environment where CSD fails with  ORA-00911: invalid character. The reason for this issue could be the backslash character specified in the file names. 

As per Oracle Forward slash (/) and backslash (\) are interchangeable in file names. Both ways should be supported by oracle. But in some cases especially in windows environment creating standby database fails with this error. It is resolved by modifying the file name with the forward slash


 Modify standby DB init parameters with a forward slash and restart the CSD.

control_files = +DATA/ORA18C/control01.ctl, +DATA/ORA18C/control02.ctl
