Only the parameters for which isModifiable is set to "True" can be changed.
If applyType is set to "static", the changes will take effect only after the next restart. applyMethod can only be set to "pending-reboot"; an error will occur if applyMethod is set to ""immediate".
If applyType is set to "dynamic" and applyMethod is set to "immediate", then "immediate" is reflected. In this case, the DB does not need to be restarted.
For details on the DB parameter groups that can be changed, refer to "Appendix A.1 List of DB Parameters That Can Be Changed" in "Appendix A List of DB Parameters That Can Be Changed" in the "Database Service User Guide".
