Hi all, By default database auto starts with init pfile when reboot windows DB machine. In order to make database autostart using spfile, I edited registry key ORA_<SID>_PFILE from '...\init<SID>.ora' to '...\SPFILE<SID>.ora', but database does not auto start when the service restarted or machine rebooted, seems it does not take the binary file. Is there a way to make the database service use spfile to auto start database on Windows environment? Thanks, Lu
