About HP DCE/9000 Version 1.7

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

recompile due to the versioning of libdce and libcma in HP-UX 11.0.

HP DCE 1.7 supports binary compatibility with HP DCE 1.2.1 and later

releases. Applications linked with the archived HP DCE 1.2, 1.2.1, 1.3.1,

1.4, 1.4.1, 1.4.2, and 1.5 libdce are fully compatible with applications

built with HP DCE 1.7 libraries. These applications can share login

contexts and credentials without loss of data.

Binary compatibility for statically-linked HP DCE 1.2, 1.2.1, 1.3.1, 1.4,

1.4.1, 1.4.2, and 1.5 applications can be disabled, resulting in minor

performance gains and slightly smaller credentials ﬁles. By default,

binary compatibility is enabled when HP DCE 1.7 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
