Packaging - Background
• Sys V like packaging
• Based on experiencing from Solaris, HP-UX, NetWare 3.x,
and NetWare 4.x
• WinInstall & InstallShield was not sufficient
• Run Time packages
• Support for NT Servers, NetWare Servers, NT Workstations

Packaging - NT applications
• Server components - files (dictionaries etc).
• Machine components - files (DLL/EXE) & registry (HKLM)
• User Components - files (INI/DAT) & registry (HKCU)

Packaging Classes: registry, files, path, environment,….
Packaging Variables: independent of directory structures
Declarative (prototyp.txt)
Dependencies: Installation- and Run-Time
Server based Installation & Local Installation.
Pkgmk, pkgadd, pkgrm, pkgchk …

EUPSRV - Workstation/Server Components
•

•
NT service running under local system account
Using Credential to access the package server
Poll mode: Wakes up regularly to check for status change
Push mode: Start from SMS job or ZEN client
Handles restarts requested by packages
Verify if user is logged in
Run pre- and post-batch script
Same service for NT Server, Workstation, and Laptop

Machine’s Current State
• Determine the Current State of the machine:
– Determine set of packages installed
– For each package determine: installation mode & installation time,
installation status, f&p server
• Machine Current State - %SystemRoot%\Config\PkgInfo\
….
office_5_un_5.0\pkginfo.ini
ubsgnu_4_un_1.4\pkginfo.ini
ubsperl_5_un_1.5\pkginfo.ini
...

Machine’s Target State
• Read the Target State from the configuration database
– list of packages with installation mode (local, shared, or exported)
• Machine Target State:
…
UBSGNU_4_UN_1.5=LOCAL
UBSPERL_5_UN_1. 4=LOCAL
OFFICE_5_IE_5.0=SHARED
OUTLOOK_4_IE_5.11=SHARED
...

Packages to Remove or Add
• Determine set of Packages 2 Remove = all packages not in
the Target State but in the Current State
ubsgnu_4_un_1.4
ubsperl_5_un_1.4
• Determine set of Packages 2 Install = all package in the
Target State but not in the Current State
ubsgnu_4_un_1.5
ubsperl_5_un_1.4
outlook_4_ie_5.11

Do It!
•
•
•
•
Filter out all packages not installed by service
Verify that all packages sources is present
Verify that all server based components is present
Remove packages in Packages 2 Remove set
– install reverse installation order
– handle packages requested immediate reboots
• Install the packages the Packages 2 Install set
– installation order as listed in the configuration database

EUPLOGON - User Components
•
•
•
•
•
Invoked at user logon via UserInit HKLM
Compares packaging installed in the “user profile”
Against packages installed on the current machine
Package customize via pre- and post-batch files
Only remove user components locally installed

The Good, the Bad & the Ugly
•
•
•
•
System in operation since autumn 1997
Mechanism not bound packaging
Overwrite versus pkgrm + pkgadd
Centralized local states versus distributed of installed
package
• Integration Microsoft SMS
– Same version of server based packages
– 100% of packages delivered to SMS distribution servers
•
•
•
•
Poll versus Push mode
Centralized configuration database versus files
Packaging Guidelines together with tools
Microsoft Software Installer (MSI)
