Modifying DB parameter group parameters
- 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".
