IBM Lotus®
@ UZH – History
● 2005
─ The university's IT strategy retains the evaluation of a groupware containing the
usual suspects: e-mail, scheduling, contacts, tasks, mobile synchronization
─ Opting for document management, synchronous communication, workflows
─ Replacing the old solution for approx. 35,000 users
● 2007
─ Open tenders
● 2008
─ End of evaluation, final decision done by the university management
● 2009
─ Internal “Going live” with IT services
● 2010
─ Official “Going live” and migration of the 40'000 users (yes, we found some more...)
● 2011
─ Closing operations for the project

Challenges, Requirements & Why IBM Lotus®
?

Challenges
● Faculties/Institutes have very high degree of autonomy in the name of
"freedom for research and teaching".
● The instruments for the academic usage ranges from magnetic resonance
imaging (MRI), super computing up to devices suitable for outdoor use in
extreme conditions. (Sounds strange, but believe us... they want them all to
collaborate...)
● Software needed for academic usage is built on a broad range of operating
systems, some of them very exotic. (Do you really believe OS/2, AmigaOS
or OpenVMS is exotic? Don't even dare...)
● Academic work is international, public, interdisciplinary and strongly
networked. (like a good MMO...)

Challenges
● The academic user has a very mobile working environment. (you remember
the terms “outdoor” and “extreme conditions”?)
● Most people work for different Institutes/Faculties/Universities
simultaneously and are often sharing a full-time equivalent with other
people. (Guess where we found the “other” users, so the headcount went
from 35'000 up to 40'000)
● High fluctuation due to academic interchange and the nature of academic
studies.
● Most of them are university graduates... (“No, you can't use this mouse for
bio-chemical experiments... It's for your computer...”)

All these challenges lead us to...
● Requirements

● Requirements
● Requirements
● Requirements
● Some more requirements

Free choice & No standard environment
● People / institutes don't pay for the service, its free of charge, so they are
not obliged to use it. We have to SELL the service with persuasion, so it has
to be „good“.
● So let's raise the bar, as we have to meet the standards as expected by the
users (and provided by the old solution)
─ High availability from every workplace
─ Transparent service cloud needed
─ Scalable & Fast
─ Disaster-resistent (failover)
● No enforcement possible neither for an operating system, a client nor for a
version of it
─ Different deployed version of all (non-lotus) applications
─ What we try is to “enforce” at least a common “major” version of Lotus Notes

Free choice & No standard environment
● Lotus Notes support for at least the main operating systems
─ 40 % Microsoft®
Windows®
, from Windows 2000 to Windows 7
─ 40 % Apple®
Mac OS, from 9.x to OS X 10.6
─ 20 % other, mostly Linux®
of various distributions and some exotic ones
● Everything available in every bitness or flavour
● How to „close the gap“ if no Lotus Notes®
is available
─ Not all systems allow a fat client, in many cases only a light-weight client as an
imap-only-client is possible.
─ Or the OS is simply not supported
─ Open protocols to support a lot of (native) clients where Lotus Notes/iNotes is not
possible or feasible (see later)

Role centric model
● Not only the person is important, but their role is it too and it has to be
separable from the person
● Need for non personal, shared collaboration resources accessible through
access rights
● Mailfiles, Calendars, Contacts, Room/Resources, Applications, Databases,
etc
● Shared Mailbox: That's where mail-in kicks in

Multilingual
● Switzerland alone has 4 languages of the country
● Full support for different languages needed
● Combined with the role centric model this means that people need to have
the possibility to dynamically switch the language
─ Not only multilingual templates
─ Multilingual Mailfiles too...
─ And that dynamically in realtime...

Openness of data
● No vendor lock acceptable (sorry guys...)
● Possibility to extract data after work done needed
● Access to data from non proprietary client required
● Open protocols (see later) to exchange/extract/import data
● Guest users

Part of the data on foreign systems
● It is not possible for the people to have all their data they need for their work
on the lotus system. Some data has to be stored on foreign systems
● If we want that they use Lotus Notes/iNotes®
as a sole system, it will have to
support the protocols to access the data on foreign systems.
● Example
─ IMAP Implementation in Lotus Notes...
─ That's one of the main reasons we can't recommend Lotus Notes as the „one
and only“ client

Interchange with non-lotus-systems needed
● The lotus systems have to connect with non-lotus-systems
● Open standardized protocols are the key
─ IMAP/POP3 - standard for mail
─ iCal – standard to read calendar data
─ ics - to exchange calendar data in file format
─ CalDAV - standard for read/write access to calendar data incl. free/busy
─ CardDAV - upcoming standard for contacts data
─ SyncML - standard for mobile pim synchronization
─ ActiveSync - standard for mobile pim synchronization

Interchange with non-lotus systems needed
● And by the way... (sorry, we couldn't resist...)
● „Open Source & Standards are key to making our planet smarter and
improving the way we live and work. [...] IBM is an industry leader helping
governments move toward greater openness and innovation. Our
commitment and perspective on intellectual property, open standards, and
open source software emerges from our experience in the marketplace and,
equally important, from the direction in which we see information technology
taking the larger society.“
● (http://www-03.ibm.com/linux/ossstds/ - Open Source and Standards @ IBM)

Why Lotus®
?
● Clients
─ Highly heterogeneous environment at the UZH (→ diversity / autonomy)
─ Lotus Notes supports a broad client infrastructure at the different release levels
– The most important operating systems are supported for the full client
– OS X, Windows, Linux
─ Strategical importance of the web frontend: Lotus iNotes covers basic to
advanced functionality for desktop up to mobile computers
– Works with a wide range of browser, supported for the most important of
them
─ Open technology
● Server infrastructure leaves a very solid and sophisticated impression. (→
high quality)
─ Scalable!
─ Most of the time very stable
─ Also great flexibility in the host operating system for the servers
─ Extensive documentation
─ Extension possible with other Lotus products

Why Lotus®
?
● Scope of function / flexibility
─ Very broad (!) scope of function, very well covered to a great extent
─ Coverage of demands with regard to „Accessibility“ and „Usability“
(→ equal opportunity)
─ Potential for closing existing gaps
(IMAP implementation, etc.)
─ Open platform with possibilities for expansion and further development
(→ self-management / autonomy)
● Costs
─ Within a 3-5 year perspective with a favorable and transparent cost structure
─ We got a big academic discount
● License model
─ The university treats all members (~40,000) equally and offers them all the
opportunity to use the system (→ equal opportunity)
─ Flexible offer, well suited to the purposes of the UZH
─ Supplier as implementation partner

Drawbacks and Opportunities: IMAP Task
● Read / Unread, does it matter?
● PMR 68612,211,848
─ Unread Mark Inconsistency on Server with IMAP
─ Status:
– Closed
– SPR
● PMR 68751,211,848
─ Deleting mails in IMAP leads to incorrect unread marks for new mails (read
instead of unread)
─ Status:
– Closed
– Fixed in 8.5.1 via private hotfix
– Included in 8.5.2 Mainstream (SPR #TPON7MFEPW)

● How to transform that task into a transparent service (cloud)?
● External solution with a open-source imap proxy called Perdition (and the
nomen wasn't an omen)

● Challenge: Can you cluster IMAP with Lotus Domino?
─ Short answer: No
─ Long answer: Yes, now, after a long ride, you can...
● PMR 67789,211,848
─ No clustering for IMAP and no possibility to solve it with external solutions.
─ Development of a solution by IBM
─ Status:
– Closed
– Private Hotfix in 8.5.1
– Included in 8.5.2 Mainstream (SPR #YDEN7F8HBQ)
● So what's the problem?
─ For IMAP unique ids (UID) are crucial for every client
─ Without the client looses track
─ Best Solution: Guarantee on every server the same IMAP UID for the same
message (which wasn't and isn't the case)
─ Problem: UIDs aren't replicated, instead they are generated by every server

● The solution IBM provided: If we can't make them the same, at least make
sure that they differ
● Implementation of IMAP_UIDVALIDITY. If set to a different value on every
server, it guarantees that the UIDs are different.
● So, when a IMAP client fails over, no UID he knows does exist, so he will
download all messages again (drawback), but you get a stable state
(opportunity)
● We had some problems with customers complaining that they see deleted
mail again after a fail-over, but couldn't reproduce these issue. We think
these problems are based on other issues.

● IMAP Data Corruption
─ PMR 13416,999,848
─ Increasing number of error reports: Note NTxxxx was not updated in the IMAP
btree. Corruption of database.
─ Seems to happen when moving documents from one folder to another in IMAP.
─ There's even an article about it in the DominoPower Magazine, a quote from it:
"IBM suggested that we temporarily disabled IMAP on all mail files, but that was
out of question..." (http://www.dominopower.com/issues/issue201004/00002501001.html)
─ Status:
– Open / we never could really track it down
– May be fixed in 8.5.2 (Time will tell...)
● Delegation of Mailfiles
─ PMR 01921,SGC,848
─ There is a fine IMAP delegation functionality included in Lotus Domino.
─ It enables you to access other maifiles via IMAP if you got the rights
─ It maps it in the folder tree in a new folder called “Other users”

● Delegation of Mailfiles
─ Sadly, it does not work if the mailfile of the access right holder is not present on
the same server as the accessed mailfile.
─ So with about 12 Mailservers and 80'000 Mailfiles we were in trouble, especially
as we have a lot of delegations (remember the “role based”?)
─ The restriction wasn't documented anywhere. And (from a customer view) it
doesn't makes sense anyway: Why should you need your own mailfile only to
access another mailfile?
─ PMR 01921,SGC,848
─ We're still in discussion with IBM about this.
─ Status:
– Open
– CritSit

Minor Pitfalls: POP Task
● Ever seen a server sized for 10'000 users (2000 concurrent) going down on
its knees with the load of 20 POP Users?
● Don't use exact sizes! (we never did)
● And even estimated sizes are not enough (we did)
● New Notes.ini-Param in 8.5.1FP2:
─ SPR #JKUR7TY97B
─ POP3_List_Size_Estimation=1
─ Gives back 40k for every message as size.
– The 40k is a fake, but better than intensive number crunching including a
take down of the server

Lotus Traveler
● We would have preferred SyncML (Open Standard)
─ Did you know that 99% of the synchronization inside Lotus Traveler is SyncML? (except
ActiveSync)
─ But we're happy with the current solution as it works for all needed mobile OS
● Works like a charm
● Our current population:

Lotus Traveler
● Now a problem: How to cluster Lotus Traveler and to keep it transparent (as
a service)?
● You can't do this out-of-the-box, but maybe this could be a working solution
for you too:
─ Flip-Flop with a standby-server.
● Caveats: Users will do a prime sync when they flip-flop. But better than
nothing.

Multilingual and dynamic
● Think about the following situation:
─ A professor and three assistants share a mailfile
─ Two of them speak German and English, one only English and the last one only
German
─ Which language template would you apply?
● That's one of the reasons for us to have multilingual mailfiles, so the users
can choose their language dynamically
● PMR #11101,112,848, #11995,112,848 et al.
● Hot fix developed by IBM
─ ENABLE_MULTILINGUAL_FOLDERS=1 & Merger tool for the template
─ Worked great for the last 7-8 months
─ We found now a problem with Lotus Traveler which didn't synchronize the inbox
anymore by some users.
● Status:
─ Closed (Not yet anymore)
─ Included in 8.5.2: SPR #SHEZ6VLEDR, #RGAU7ZXN4T

CalDAV
● De facto standard for synchronizing calendar data
● Based on iCal – format
● Able to do read/write – access, tasks, busy/free-schedules, etc
● Implementation on many devices (iPhone...) and clients (Mozilla
Thunderbird, etc).
● IBM was talking about it since years behind the curtains
● But we haven't seen a solution yet
─ Even a subscribable read-only iCal-Feed of the calendars would be great
─ (and better than nothing)
● At the moment: No out-of-the-box solution to give third-party-co-workers a
feed about your calendar data.

Conclusion

Conclusion
● We're still happy!
● We licensed Lotus Sametime Standard one month ago for all users
● What we think about IBM as our provider and implementation partner:
─ Flexible, reactive and open minded to our needs
● But we still agree with Marie Scott (Director of E-mail Services, Virginia Commonwealth
University): “Why do universities like “free, free, free”?” ☺
