Procedure documentation Checking All Database Parameters Locate the document in its SAP Library structure

Use

You check all the database parameters using the properties, calculation formulas, and conditions stored in the description file (Configuration of Database Instances).

Prerequisites

You have opened a parameter session.

You have the server authorization ParamCheckWrite.

Syntax

param_checkall [<mode>]

Option <mode>

You use the <mode>parameter to control the behavior of the Database Manager for parameters with the check status request.

Possible values for <mode>:

No entry

The system default values are used for all parameters (necessary for background processing).

GENERAL

Only the database parameters in the General – General Database Parameters are requested with the request check status.

EXTENDED

Only the parameters in the General Database Parameters (General) 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.

Reply

If an error occurs, the database 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 the database parameter

<check_status>

The following are possible values for the check status:

Mandatory – a mandatory parameter has been assigned a blank value.

Constraint – a constraint could not be fulfilled.

Request – the operator input deviates both from the value that was transferred earlier to and confirmed by the system, and from the system default value.

<user_value>

Value that the operator entered with param_put.

<computed_value>

Default value calculated by the system

Note

The parameter changes cannot be confirmed for open requests (Confirming Changes to the Database Parameter File).

Further Procedure

Correct the parameter in question using param_putconfirm (Parameter Correction) or param_put (Changing a Parameter Value) and repeat the check with the param_checkall [<mode>] command.

The new value is registered by the system and transferred to the database parameter file as the effective value the next time the database instance is restarted.
