Dear,

Database is 12.1 with ASMM, after reboot, error occurs 'ORA-00821: Specified value of sga_target 51200M is too small, needs to be at least 51328M'. Then, I have to manipulate manually spfile/pfile to change the value of sga_target by touching hidden parameters starting with '_'. Afterwards, db is up. I checked in oracle support, this error happens during DBCA db creation and db upgrading, but never after just reboot instance.

This is for me a bug. Why only 100M makes such a big deal that database refused startup. Could this bug related to ASMM? Root cause? Have you guys other solutions?

Howdy, Stranger!
