Software replacement method and related software replacement system
View Patent ↗The present invention relates to a Software replacement method, for replacing a first software package that comprises a command handling interface which is present at a computer system, by a second software package over a connection between an operator terminal and this command handling interface. At first the second software package is installed besides the first software package at the computer system. Subsequently, the second software package is activated. Then a contacting part of the second software package, after activation of this second software package, contacts the command handling interface. The command handling interface at contacting of the command handling Interface by the contacting part of the second software package, switches from the first software package towards the second software package and keeps open the connection between the operator terminal and the command handling interface.
1. A software replacement method, said method comprising:
installing a second software package to replace a first software package comprising a command handling interface, at a computer system;
activating said second software package;
contacting said command handling interface by a contacting part of said second software package after activation of said second software package;
when said command handling interface is contacted by said contacting part of said second software package, said command handling interface switching from said first software package towards said second software package; and
keeping a connection between an operator terminal and said command handling interface open after said contacting part contacts said command handling interface,
wherein the first software package is replaced with the second software package via a connection between the operator terminal and said command handling interface, said replacement occurs at a same time as said connection, and said connection is maintained before and after said replacement.
2. A software replacement system, said system comprising:
a memory;
an installation part adapted to install a second software package besides a first software package at a computer system;
a software activation part, adapted to activate said second software package;
a contacting part, adapted to contact a command handling interface after activation of said second software package;
a switching part, adapted to switch said command handling interface from said first software package to said second software package, when said command handling interface is contacted by said second software package; and
a connection persisting part, adapted to keep said connection between an operator terminal and said command handling interface open after contacting said command handling interface is contacted by said contacting part,
wherein the first software package is replaced with the second software package via a connection between the operator terminal and said command handling interface, said replacement occurs at a same time as said connection, and said connection is maintained before and after said replacement.
3. The software replacement method according to claim 1 , wherein the first software package and the second software package are not simultaneously active at the computer system.
4. The software replacement system according to claim 2 , wherein the first software package and the second software package are not simultaneously active at the computer system.
