Opening the Parameter History 

Use

Open the parameter history and transfer the first block of the contents. The entries are output in reverse chronological sequence, that is, starting with the most recent and ending with the oldest.

You can limit the output by specifying options. If you enter several selection criteria, then only those parameter changes that correspond to all the criteria are output.

If the parameter history entries have been incompletely transferred, you can call up the rest of the contents using the command for scrolling through the parameter history.

Prerequisites

You have the DBM operator authorization ParamRead.

Syntax

param_gethistory [fields=<fieldlist>] [name=<paramname>] [date=<yyyymmdd>] [group=<grouplist>] [state=<statelist>]

Example

Options

<fieldlist>

You can limit the quantity of the parameter history fields supplied by the DBM Server by specifying a field list.
Enter the fields that you want output here using a comma as a separator.
The fields you select will always be output in the following sequence:

Possible entries:

DATE Date of the parameter change (YYYYMMDD)
TIME Time when parameter was changed (00HHMMSS)
NAME Name of the parameter
NEWVALUE New value of the parameter
OLDVALUE Old value of the parameter
STATE The change status of the parameter
GROUP Group to which the parameter is assigned

If you do not specify a field list, then all fields will be output.

<paramname>

You can display the history of one specific parameter by specifying the parameter name.
If you do not specify a parameter name, then the entries for all parameters in the parameter history will be displayed.

<yyyymmdd>

If you specify a date, then only those parameter changes that have taken place since this date will be output.
If you do not specify a date, then all entries in the parameter history will be supplied.

<grouplist>

You can limit the parameters for which the changes are output by specifying a parameter group. Use a comma to separate entries.

Possible entries are: GENERAL, EXTENDED, SUPPORT

If you do not specify a parameter group, then the parameter changes for all groups will be output.

<statelist>

You can specify the change state to determine whether active, changed or deleted parameters should be output. Use a comma to separate entries.

Possible entries are: A (active), C (changed), D (deleted)

if you do not specify a state, then all parameter changes will be output.
