2.4.1 Installing packages with installation timing specified
Unless otherwise specified, packages distributed to the distribution-destination system are immediately installed into the distribution-destination system. However, the installation fails if that software is in use or running in the distribution-destination system. To prevent such a problem, you can set an installation timing for the packages.
Specify the installation timing during the registration or distribution of software. The following installation timings can be specified.
-
During system startup
-
During system operation
-
During system stop
When installation during system startup or during system stop is selected, the distributed package is stored in the hard disk of the distribution-destination system until installation.
When specifying the installation timing, note the following:
- Organization of this subsection

Installation requires extra hard disk space equivalent to the size of the package to be installed. Estimate the size of the hard disk during installation, by referring to 5.2 Estimating of the disk space and memory requirements in PART 2.
-
The system file must be set during installation. For details on the setting procedure, see 5.8 Setting the system files in PART 2.
