Interoperability and Compatibility
This section describes the interoperability of this release with various
implementations of OSF DCE, and its compatibility with previous
versions of HP-UX DCE, and with DCE-related technologies.
Binary Compatibility with Previous HP-UX DCE
Releases
HP-UX DCE 2.0 supports binary compatibility with HP-UX DCE 1.2.1
and later releases. Applications linked with the archived HP-UX DCE
1.2, 1.2.1, 1.3.1, 1.4, 1.4.1, 1.4.2, 1.5, 1.6, or 1.7 libdce are fully
compatible with applications built with HP-UX DCE 2.0 libraries. These
applications can share login contexts and credentials without loss of
data.
Binary compatibility for all statically-linked HP-UX DCE versions can be
disabled, resulting in minor performance gains and slightly smaller
credentials files. By default, binary compatibility is enabled when
HP-UX DCE 2.0 is installed and configured. You can disable binary
compatibility on a per-host basis with the following commands:
# ps -ef|grep dced
# kill <dced PID#>
# /opt/dce/sbin/dced -r
# ps -ef|grep dced
# kill -SIGUSR1 <dced pid#>
# dcecp -localdcecp> acl mod hostdata -change {user
hosts/$HOST/self criI} -localdcecp> acl mod hostdata
-io -change {users hosts/$HOST/self cdprw} -localdcecp> quit
# kill -SIGUSR1 <dced pid#>dcecp>dcecp> hostvar set
-secbinarycompat off
To enable binary compatibility after it has been disabled, complete the
following steps:
1. Enter the following command:
dcecp> hostvar set -secbinarycompat on
2. Stop and restart the DCE daemons.
3. If you are using Integrated Login, log out and log in.
