Every property defined in the System Properties application has options that you can manage.
| Property options | Description |
|---|---|
| File override | Specifies whether the property and its value are loaded from a file rather than from the database. |
| Global only | Specifies whether this property must exist only at a system-wide level, and implies that the property cannot be overridden at the instance level. |
| Instance only | Specifies whether this property must be defined at the instance level. If the property must be defined at the instance level, you provide an instance-specific value and the property is not a global value. |
| Online changes allowed | Specifies whether the System Properties application is used to change the value for the property. For example, the global property mxe.db.driver does not allow online changes. |
| Live refresh | Specifies whether the property value can take effect immediately after saving the value. |
| Encrypted | Specifies whether the property is stored in an encrypted manner in the underlying product database. The value is encrypted by using the standard encryption functions for the product. For example, the global property mxe.int.uddipassword is encrypted. |
| Security level | Specifies the level of access to this property
by various product components.
|
| User defined | Specifies whether the property is created by a user or if the property is provided with the product. |
| Nulls allowed | Specifies whether the property can have null values. You can change this characteristic only for user-defined properties. |
| Data type | Specifies the type of value that can be provided
for the property. The value can be an integer, alphanumeric, or a
yes or no (YORN). For example, the global property mxe.allowLocalObjectsmxe.int.uddipassword is associated with the YORN data type. If you specify a value other than 1 or 0, an error message is displayed that indicates the value is invalid. |
| Domain | Specifies a domain that provides a list of values to which the property can be set. For example, the mxe.db.transaction_isolation global property is associated with the TRANSISO domain. Therefore, the values for the property must match a corresponding domain value. |
| Masked | Specifies whether the global and default values are hidden on the user interface. |
