What happens if you want to create the following extra file systems (for an application)?

/opt/application

/opt/application/static

/var/opt/application

/var/opt/application/data

/var/opt/application/tmp

Ignite-UX has no information about what data might be stored in these file systems because it has no impacts statements that affect them. Suppose that the impacts are only one level deep and everything is being tracked against /var and /opt for the application:

impacts = "/opt" 1048576Kb impacts = "/var " 3673088Kb

If you create those extra file systems, you might easily misjudge their size. Because the impacts statements have tracked all of the space against /var and /opt, Ignite-UX cannot know how much space is needed under those file systems so it does not alert you. If your situation is like this, it would make sense to set up your own Ignite-UX server with the correct impacts keywords rather than attempting to use installation media.

Assume that the file systems needed for this application are those in Table 5:

Table 5

Mount point

File System Size (Mb)

Space Used (Mb)

 

 

 

/opt/application/

1024Mb

768Mb

/opt/application/static

512Mb

384Mb

/var/opt/application

2048Mb

1512Mb

/var/opt/application/data

16384Mb

2011Mb

/var/opt/application/tmp

16384Mb

64Mb

Impacts statements for the sw_sel clause associated with this application look like the following:

impacts = "/opt/application"

786432Kb

impacts = "/opt/application/static"

393216Kb

impacts = "/var/opt/application"

1548288Kb

impacts

=

"/var/opt/application/data"

2059264Kb

impacts

=

"/var/opt/application/tmp"

65536Kb

The impacts statements place the required impacts at the places where the application (in the environment in which it is installed) has mount points. With this information, Ignite-UX is aware of the impacts associated with each file system.

Creating impacts in this manner (for our optional application with only five impacts statements at up to four levels deep) is a manual job for two reasons:

First, Ignite-UX normally creates impacts at every directory up to the level that you specify. If you have an archive and you use the archive_impact command to generate the impacts with the option –l 4, the archive_impact command lists the space used in every directory up to the fourth level deep. With a large directory structure, this can generate thousands of impacts
