HSMS must be installed jointly by the system administrator and the HSMS administrator. The system manager has to run the respective IMON installation for HSMS. During this IMON installation, all necessary files for ARCHIVE are also installed.
When the system administrator initially loads HSMS, this is done in the operating mode DEFINE-SHOW, i.e. no action statements are as yet executed by HSMS. The HSMS administrator subsequently sets the control parameters and switches over to OPERATION mode.
Before installing a new HSMS version, the system administrator must find out what is required of the system environment and whether the different HSMS versions are compatible. In section "Compatibility of HSMS definitions in different HSMS environments" there is an explanation of how to perform a version upgrade and downgrade and which HSMS versions are compatible for processing shared pubsets. This section should be read very carefully, as the loss of a control file can also lead to the loss of the entire HSMS environment.
Since HSMS is often introduced in environments which used to use the software product ARCHIVE, the directory files created by ARCHIVE can be retained under HSMS. The directory files created by ARCHIVE can be retained under HSMS (see section "Special aspects when switching from ARCHIVE to HSMS operation").
