Changed Features in HP-UX DCE 1.9

This section describes features that have changed in HP-UX DCE 1.9.

Control Programs and Daemons

HP-UX DCE 1.4.x replaced the following control programs with dcecp. HP-UX DCE 1.6 and 1.7 support these

programs for transition purposes only. HP-UX DCE 1.9 does not support them. If you use any scripts

referencing these programs, modify these scripts to use dcecp instead.

• cdscp

• rpccp

• dtscp

• rgy_edit

• sec_admin

• acl_edit

The following daemons no longer exist:

• sec_clientd

• rpcd

• cdsclerk

dced replaces sec_clientd and rpcd. As of HP-UX DCE 1.4.x, a symbolic link permits you to run dced as

rpcd.The functionality of cdsclerk is part of cdsadv in HP-UX DCE 1.4.x. You need to modify any scripts or

programs that reference these non-existent daemons.

Support for POSIX 1003.1c Threads

You must migrate CMA applications from Draft 4 of the POSIX threads standard to the ﬁnal, ratiﬁed 1003.1c

standard for kernel threads. When you migrate to Draft 4, there will be some incompatibility. HP

recommends that you complete the following steps:

• Isolate new threads API usage to macros or wrapper APIs.

• Minimize the use of signals, and use only POSIX semantics when programming with signals.

For example, threaded applications use only the functions sigaction(), sigprocmask(), and sigwait().

If you have CMA applications running on a PA platform, you can use them on IA. However, you cannot

recompile these applications on IA without porting them to kernel threads.
