You check all database parameters using the properties, calculation formulas, and conditions stored in the description file (Configuring Database Instances).
You have opened a parameter session.
You have the server authorization ParamCheckWrite.
param_checkall [<mode>]
Using the parameter <mode>, you can control the behavior of the Database Manager for parameters with the check status request.
Possible values of <mode>:
No entry |
The system default values are used for all parameters (necessary for background processing). |
GENERAL |
Only the parameters from the group General - General Database Parameters are requested during the check status request. |
EXTENDED |
Only the parameters from the groups General Database Parameters and Special Database Parameters (Extended) are checked. |
SUPPORT |
This option is only relevant for Support. All parameters (from the groups General, Extended, and Support) are checked. |
If an error occurs the database parameter check is canceled with an error message.
ERR

<parameter_name>
<check_status>
<user_value>
<computed_value>
<parameter_name> |
Name of the 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).
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.
