How to delete data from SSdb under specific conditions.

[MARUBUN SUPPORT]

Hi Team,

OS：RHEL9.5
Spectrum 24.3.9 

SSdbload shows the following:

Landscape   Hostname          Port    Precedence
----------  ----------------  ------  ----------
0x1000000   ss01lab           0xbeef  10       
0x1000000   ss01w             0xbeef  20       

Here, ss01w and ss01lab are the hostnames of ss in different environments (commercial environment and lab environment), and it appears that at some point someone mistakenly restored a backup of the commercial environment to the lab environment.
There are no backup files remaining that do not contain ss01w information, so it is not possible to restore a normal backup file to the state where only ss01lab is in SSdb.
In this situation, is there a way to delete just the data for Precedence:20, Hostname:ss01w?

Can this be fixed with MapUpdate?

Thanks,
