The SCI contains a great deal of metadata, such as information about opened deliveries, installed supply items, added installation units and installation items. Some of this information is obsolete and should be removed from the SCI. Obsolete information can be identified and deleted on the following levels and in the order shown:
Delivery
Installation unit
Installation item
Identifying and removing obsolete deliveries
The information about a delivery is needed as long as a supply unit can be installed from it.
This applies in the following cases:
One or more supply units in the delivery are in the installation status “In Library”, “On SOLIS2 Volume”, “On Local Volume” or “Parked”.
The user wants to reinstall a supply unit again.
As soon as no more supply units are to be installed from it, all information from the delivery can be removed from the SCI and optionally all work files belonging to it can be deleted, with the statement REMOVE-PACKAGES or the menu function Edit:Remove.All supply units, which are not in the installation status “Installed”, are deleted with the delivery.
To locate deliveries, which are no longer needed by users and can be deleted, further selection criteria are available to the user in the SELECT operand of the SHOW-PACKAGES statement or the Filter packages dialog box of the menu function View:Packages (deliveries), as well as from creation date, change date of the delivery and the installation status of the supply units which belong to it.
Note
A supply unit of a delivery can be in an installation status other than “Installed”, and still be installed, if the installation has taken place from another delivery. In this case, a “*” is displayed in the marker column of the supply unit.
Identifying and removing obsolete supply units
The information about a supply unit is obsolete in the following cases:
The supply unit is in the installation status “Installed” and the user does not wish to execute the installation again.
New versions of the supply units have been installed and the user no longer needs the older versions.
The supply unit is in the installation status “Installed”, but it contains no installation units.
Supply units, which are in the installation status “Installed” or “Parked” and are no longer needed, can be deleted through the deinstallation function. All other supply units can be deleted with the statement REMOVE-SUPPLY-UNITS or the menu function Edit:Remove.
To identify and locate deliveries, which are not in the installation status “Installed”, the user can employ installation status as a selection criterion in the SHOW-SUPPLY-UNITS statement in the SELECT operand, or the Filter supply units dialog box in the View:Supply units menu function.
Deliveries in the installation status “Installed” or “Parked”, which can only be deinstalled, can be identified and located in a similar way. As a check, the deinstallation should be carried out first in test mode and then if applicable started normally. During deinstallation, all files belonging to it are deleted.
Identifying and removing obsolete installation units
The information about an installation unit is obsolete if a higher version is installed and the other versions are no longer used.
In menu mode, all versions of an installation unit from the open SCI are displayed in the work area. The user can select the versions that are no longer needed and then call the function Edit:Remove.
