OSF DCE Administration Guide—Core Components
You could temporarily make one department’s printers available to another group by
adding its group name to the group entry of the other group as shown in the next group
entry example:
Group entry name: /.:/admin/finance/accts_payable_printers
/.:/admin/finance/accts_payable/laser_10
/.:/admin/finance/accts_payable/laser_11
/.:/admin/finance/accts_payable/laser_12
/.:/admin/finance/accts_payable/laser_13
/.:/admin/finance/accts_receivable_printers
The configuration in the preceding example means the clients in accounts payable can
use the printers in accounts receivable 20% of the time. You could offer a higher
percentage of use by adding server entry names rather than the group name. The next
group entry example shows a situation where the clients in accounts payable can use the
printers in accounts receivable 50% of the time. However, don’t try to increase the
percentage of use by including a group name multiple times because you’ll get an error.
Group entry name: /.:/admin/finance/accts_payable_printers
/.:/admin/finance/accts_payable/laser_10
/.:/admin/finance/accts_payable/laser_11
/.:/admin/finance/accts_payable/laser_12
/.:/admin/finance/accts_payable/laser_13
/.:/admin/finance/accts_receivable/laser_10
/.:/admin/finance/accts_receivable/laser_11
/.:/admin/finance/accts_receivable/laser_12
/.:/admin/finance/accts_receivable/laser_13
Although application servers can manage their own group entries in CDS, you may find
it more convenient (and more straightforward) to manually add, remove, or change server
information in a group entry. Like managing server entries, there are several methods for
managing group entries in CDS:
• Group entry names can be hardcoded into an application. You can change group
entry information in the source code, but you need to recompile and rerun the
application before the entry names take effect.
• Group entry names can be passed to an application through environment variables or
arguments. These are more convenient methods than recompiling, but you might
need to restart an application to use either method.
• Group entry names can be directly managed in CDS by using the DCE control
program’s rpcgroup object. This manual method does not require recompiling or
restarting applications.
The next sections discuss how to use the rpcgroup object to manually manage group
entries in CDS.
