The system support can change the parameter file presettings with a file editor. Note, however, that the changes become effective only when ARCHIVE is loaded again with DSSM.
When changing the presettings the system support must take great care, because syntax errors in the parameter file will cause the ARCHIVE load operation to be aborted or will cause internal errors during execution.
The following rules should be observed when changing the default settings:
The parameter file is not checked for completeness. If parameters are missing, the default values will be used.
An asterisk “*” in column 1 indicates a comment line.
Only one record per operand is permitted.
Nothing to the left of the equals sign '=' may be changed.
The value for a parameter must be entered immediately after the equals sign '='.
If several definitions are entered for one operand, the last assignment is used.
For safety reasons the system support should log the presettings, either by adding comments to the standard records or by copying the parameter file.
The current operand values can be displayed via the SHOW-DEFAULT statement of ARCHIVE once the subsystem has been loaded.
