About HP DCE/9000 Version 1.8

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 DCE, and with DCE-related technologies.

Binary Compatibility with Previous HP DCE Releases

Applications built on HP-UX 10.30 with HP DCE 1.6 may need to

recomplile due to the versioning of libdce and libcma in HP-UX 11i. HP

DCE 1.8 supports binary compatibility with HP DCE 1.7 and later

releases. Applications linked with the archived HP DCE 1.7 libdce are

fully compatible with applications built with HP DCE 1.8 libraries.

These applications can share login contexts and credentials without loss

of data.

By default, binary compatibility is enabled when HP DCE 1.8 is installed

and conﬁgured. You may 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 -local

dcecp> acl mod hostdata -change

{user hosts/$HOST/self criI} -local

dcecp> acl mod hostdata -io -change

{users hosts/$HOST/self cdprw} -local

dcecp> quit

#kill -SIGUSR1 <dced pid#>

dcecp>

dcecp> hostvar set -secbinarycompat off

To enable binary compatibility after it has been disabled, do the

following:

1. Issue the command:

dcecp> hostvar set -secbinarycompat on

2. Stop and restart DCE daemons.
