For more information on creating a password file, see Creating and Maintaining a Password File in the Oracle Database Administrator’s Guide. |

3 |
Auxiliary instance destination directories exist: The following destination directories for the auxiliary instance must be created on the server where the destination database resides. If the destination database stores its datafiles in ASM, the ASM instance name for the destination database must exist. |
4 |
PFILE created for auxiliary instance: A client-side PFILE for the Auxiliary Database must be created from the SPFILE of the source database. |
• |
Start SQL*Plus, and connect with administrator privileges to the source database. |
5 |
PFILE updated with auxiliary values: The PFILE created for the auxiliary instance must be updated with the parameter values specific to the auxiliary instance. |
