Check All Parameters 

Use

You analyze the whole set of all parameters.

Prerequisites

You have opened a parameter session.

You have the DBM operator authorization ParamCheckWrite.

Syntax

param_checkall [<mode>]

Option <mode>

With the parameter <mode> you control the behavior of the parameter manager in 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 - General Database Parameters and Extended - Special Database Parameters are checked.

SUPPORT

This option is only relevant for support. All parameters (from the groups General, Extended and Support) are checked.

Reply

If an error occurs the parameter check is canceled with an error message.

ERR
14,ERR_XPCHECK_CN00 : param check failure/request
<parameter_name> <check_status>
<user_value>
<computed_value>

<parameter_name>

Name of parameter

<check_status>

The following check statuses may occur:

Mandatory – An obligatory parameter has been assigned a blank value.

Constraint – a constraint could not be fulfilled.

Request – the user 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 user entered with param_put.

<computed_value>

Default value calculated by the system

For open requests the parameter changes cannot be confirmed (parameter change confirmation).

Continuation of Procedure

Correct the parameter in question using param_putconfirm (correcting parameters) or param_put (parameter value change)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 effective value when the database instance is restarted.
