    Ciao Fernando, I’ve just had a look on your step-by-step RAC standby creation, and I see you first copy your pwfile to the standby machine at OS level in orahome/dbs directory… I’ve been struggling to create a standby with its pwfile copied from primary DB directly within ASM, to no avail.
    RMAN script shows indeed
    ~ passwordfile auxiliary format ‘/u01/app/oracle/product/’;

    so I guess it confirms that so far *it is not possible to make a standby using ASM-based password file at the very beginning* of the process… ?

    Thanks a lot anyway cause this page seems to confirm this, and it solved my issue !

      Thanks for your message.
      I think that yes, is completely possible to create the standby directly with the password file at ASM.
      But, I think that this depends on the process/command that you use to generate your standby. If you use duplicate, I think that will not be possible. If you look here: http://www.fernandosimon.com/blog/wp-content/uploads/2019/11/Steps-RAC-RAC-DG-Creation.txt you will see that duplicate uses the orapw. If you use backup/restore manually, will be easier to do that (I think). But recommends you to test.
      Sorry for the delay to reply your message.
      Best regards.

      Fernando Simon
