Hi @尹俊权

welcome to the Atlassian Community!

Without knowing your system better the ERROR message is the same like in this Community post. It suggests, the database is read-only in a moment where an update statement (to change some data in it) should be made:

https://community.atlassian.com/t5/Crowd-questions/Any-help-on-fixing-this-error-would-be-appreciated/qaq-p/985473

Maybe you can work this out with a database professional rather on your end. From within Community it will be hard to say presumable how the configuration you have could add to this encounter.

Daniel
