 Opening the Database Parameter History 

Use

You open the database 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 database parameter history.

Prerequisites

You have the server authorization ParamRead.

Syntax

param_gethistory [fields=<field_list>] [name=<parameter_name>] [date=<yyyymmdd>] [group=<group_list>] [state=<state_list>]
