Software Distributor Administration Guide HP-UX 11i v1, 11i v2, and 11i v3 (5900-2561, March 2013)

Registration provides a type of public recognition for the packaged depot:
• You can see the depot in the swinstall/swcopy GUI and see it in swlist depot-level
listings.
• You can read products from the depot (for example, to install).
For more information about registering depots, see “Registering and Unregistering Depots (swreg)
” (page 95).
NOTE: If the only use of a depot created with swpackage is local access by the packaging
user, depot registration is not required.
10.6.2 Creating and Mastering a CD-ROM Depot
When swpackage creates a new depot or packages a new product, it always creates an ACL
for the depot/product. If you were to create a depot and then master it onto a CD-ROM, the
CD-ROM would contain all those ACLs, which could cause the following problems:
• it may result in too-restrictive permissions on the CD-ROM depot.
• you could have too many user-specific ACLs on the CD-ROM.
To solve these problems, you can tell swpackage to not create ACLs in the depot by setting the
create_target_acls option to false.
This feature is provided only for the superuser because only the local superuser can change, delete,
or add ACLs to a depot that has no ACLs. The local superuser always has all permissions.
Setting the create_target_acls to false causes swpackage to skip the creation of ACLs for
each new product being packaged (and for the depot, if it is new). This option has no impact on
the ACLs that already exist in the depot.
When a depot is used as a source for other SD-UX operations, its ACLs (or lack of ACLs) have no
bearing on the ACLs created for the targets of the operation. Source ACLs are not related to target
ACLs.
The swpackage command never creates ACLs when software is packaged onto a tape.
10.6.3 Compressing Files to Increase Performance
The packaging process may pass large amounts of data back and forth over the network and
might slow down network performance. The compress_files option can improve performance
by first compressing files that are to be transferred. This performance gained depends on the type
of files transferred. Binary files compress less than 50%, text files generally compress more.
Improvements are best when transfers are across a slow network (approximately 50Kbytes/second
or less).
If set to true, compress_files compresses files (if they have not been compressed previously
by SD-UX) before transfer from a source. You may also specify a compression type with the
compression_type option or specify a compression command with the compression_command
option.
This option should be set to true only when network bandwidth is clearly restricting total throughput.
If it is not clear that this option will help, compare packaging operations both with and without
compression before consistently using this option. See Appendix A (page 235) for more information
on using command options.
NOTE: swpackage cannot compress files when writing to a tape.
10.6.4 Packaging Security
SD-UX provides Access Control Lists (ACLs) to authorize who has permission to perform specific
operations on depots. Because the swpackage command creates and modifies local depots only,
