Description/Symptoms
====================

Client Notification Daemon (pdconntf):
    Files:
        /usr/pd/lib/pdconntf
        /usr/pd/man/man1/pdconntf.1
        /usr/pd/scripts/apx.init

    Problem Addressed:

    In V1.0, the client notification daemon, pdconntf, starts at system boot,
    and runs continuously until the system is shut down.  If it has permission,
    it connects to the current X-session to listen for notification messages
    from Advanced Printing Software Servers (which are sent using the ToolTalk
    protocol).  However, if pdconntf did not have access to the current X
    session, it would keep trying forever.  On many systems (particularly
    those running with C2 security), each attempt was logged in the
    /var/dt/Xerrors file, sometimes at the rate of 1-per-second.

    This patch modifies pdconntf to only run while it has access to an
    X session.  pdconntf is no longer started when the system is booted.
    If a user wishes to have console messages from Advanced Printing Software,
    pdconntf should be started when logged into a CDE or other X session as
    follows:
		/usr/pd/lib/pdconntf

Local Namespace Corruption:
    Files:
        /usr/pd/lib/libpdcore.so

    Problem Addressed:

    This patch fixes a problem with contention for the "local file" or "etc"
    namespace file (/etc/printers.conf), which could cause namespace
    corruption if multiple Advanced Printing Software servers are active
    on a single system.   In addition, server startup and NIS name lookup
    performance should be improved.

Installation Instructions

This ECO applies to all Advanced Printing Software installations.  Note
also that new systems that came Factory Installed with Tru64 UNIX V4.0F
and later may have Advanced Printing Software preinstalled.  These systems
should also apply this ECO.

Installation of this ECO requires the subset APXBASE100 to have been previously
installed.  During the installation process, updated files will be replaced.
To install this ECO, use the setld command:

	# setld -l <directory_where_eco_was_downloaded>

Once the ECO installation is completed, Compaq recommends you stop all
Advanced Printing Software processes on the system and restart them for the
changes to take effect:

        # /sbin/init.d/apx stop
        # /sbin/init.d/apx start

To remove this ECO, use setld to delete the ECO subset.  When the subset
it de-installed, the original files will be replaced.

	#  setld -d APXBASE100ECO001
