Per modificare un gruppo di parametri DB

L'modify-db-parameter-groupesempio seguente modifica il valore del clr enabled parametro in un gruppo di parametri DB. Il --apply-immediately parametro fa sì che il gruppo di parametri DB venga modificato immediatamente, anziché attendere la finestra di manutenzione successiva.

aws rds modify-db-parameter-group \
    --db-parameter-group-name test-sqlserver-se-2017 \
    --parameters "ParameterName='clr enabled',ParameterValue=1,ApplyMethod=immediate"

Output:

{
    "DBParameterGroupName": "test-sqlserver-se-2017"
}
