<parameter_name> |
Name of database parameter |
|
<check_status> |
The following are possible values for the check status: Mandatory – An obligatory parameter has been assigned a blank value.Constraint – a constraint could not be fulfilled.Request – the operator input deviates both from the value transferred to the system and confirmed by it earlier, as well as from the system default value. |
|
<user_value> |
Value that the operator entered with param_put. |
|
<computed_value> |
Default value calculated by the system |

For open
requests the parameter changes cannot be confirmed (Confirming Changes to the Database Parameter File).Continuation of Procedure
Correct the parameter in question using
param_putconfirm (parameter correction) or param_put (change a parameter value)and carry out a new check with the command param_checkall [<mode>].The new parameter value is registered by the system, and is transferred to the parameter file as the valid value at the next
restart of the database instance.
