“Self Healing Clients” ensure Client continuity for ongoing TCO savings
Classic Helpdesk client management only offers remote
management
• 1,000 helpdesk calls remain 1,000 management
incidents
• Repeated efforts lead to limited, over time decreasing
benefits
→ Only reduces time spent on each helpdesk call

“Self Healing Clients” ensure Client continuity for ongoing TCO savings
MarvelClient is similar to an email spam-filter: Centrally
created actions solve helpdesk incidents automatically
• Actions are permanently enforced
• Benefits increase over time and can reduce helpdesk
calls by up to 80%
→ Reduces number of helpdesk calls AND time

Marvel Client Upgrade Free
www.panagenda.com/free-upgrade

Upgrades
V10.0.1 FP1 + Language Kit G1

What we see out there in Notes deployments
• Lack of visibility and control
• Many different versions and many different installation types
• Uncontrolled configurations (Data Dirs, Locations, Connections, Accounts,
Settings, Eclipse preferences, …)
• Not secure (JVM vulnerabilities, Code Signers, ECL Management)
• Mixed functionality – things don’t work!
• The same end-user problems occur again and again (and again)

What we see out there in Notes deployments (2)
• Reluctance to upgrade
• Software deployment teams have little/no knowledge or “care factor” about
Notes
• Administrators lack time and skill to utilize all available tools to effectively
manage the Notes client
• Perception → it's too difficult and/or expensive / too risky for the business
due to disruptions

Know your current environment
• It’s fundamentally important that your know the details about your current
Notes Client Infrastructure to be able to make smart decisions for future
deployments
– Which exact versions are deployed?
– Which Installation types and modes are used?
– Locations of Program-, Data- and SharedData-Dir?
– Usage of Laptops, Desktops, Citrix and VDI in numbers/percentage?
– Which OS incl. version is used?
– Usage of Notes addons → Connections plugins, SwiftFile, CTI, … ?
• If you can’t answer the questions above 100% correctly, the following two
slides will help you a lot!

MarvelClient Essentials – AnalyzeDB examples

MarvelClient Essentials – AnalyzeDB examples (2)

Define target (version and more …)
• Version is very easy at the moment → 10.0.1 FP1

• Which Client Package?
– Standard, Basic and/or ICAA (IBM Client Application Access)
• Which Installation type?
– Single or MultiUser

Define target (version and more …) (2)
• Adding languages using MUI-Pack installation(s)
– Multilingual User Interface
– Group1, 2a, 2b and 3 → Group1 was finally released on 5th Feb 2019 – but 
– Group1 is available again ☺
• Current status for languages
– Group 1
– Group 2 languages (later → ~ same eGA as FP2) ?

Notes/Domino v11 Language Kits
• Re-engineering language kit generation process
• Selected language kits will be available for betas
• Simultaneous ship language kits with Domino v11
• Ship language kit fix packs as necessary

• Where to deploy?
– Laptops, Desktops, Citrix and/or VDI
– Windows7, Windows10, macOS 10.13 and/or macOS 10.14

• Adding other functions/packages?
– Sametime embedded → not needed, 10.0.1 is up-to-date
– JVMPatch → not needed, 10.0.1 is up-to-date
– SwiftFile → use latest version 4.2.1 here
http://www-01.ibm.com/support/docview.wss?uid=swg24035896
− IBM Connections Plugins for Notes → use latest version 5.5.0.20180813-1729 here
https://xspy.mybluemix.net/nx OR directly at HCL
− Programs/Applications who interacts/communicates with Notes
CTI, Instant Messengers, …

• Let’s assume (for this session) you want to Upgrade from Notes 9.0.1 FPx IFx to the following
components:
– IBM Notes 10.0.1 Standard Client → MultiUser Installation on Windows10 64Bit
– Add French and Japanese (Multilingual User Interface = MUI)
– Fix Pack 1
– SwiftFile 4.2.1
– Connections Plugins for Notes 5.5.0.20180813-1729
– Use of default paths for
Program directory
C:Program Files(x86)IBMNotes
Shared data directory
C:ProgramDataIBMNotesDatashared
Data directory
C:Users<USERNAME>AppDataLocalIBMNotesData

Choose Upgrade/Deployment Tool – Third-Party-Solutions
• Third-Party-Solution for Notes → Today: Marvel Client Upgrade Free
• Third-Party-Solutions for Windows, like
– SCCM
– Empirum
– LanDesk
– DSM
– others

Choose Upgrade/Deployment Tool – Notes Smart Upgrade
For many many reasons
We “personally” do not recommend to use “Notes Smart Upgrade”

Create Upgrade Package
• No need to make changes to MSI package(s)
– Scripts can help here
– Differentiation between package and configuration (notes.ini, ConfigFile, etc.)
– That will help you a lot when it comes to package changes, new versions and testing
• Always include an Uninstall part in your package
– In-place upgrades are not recommended
– You can use the package also in cases of a new or re-install

Create Upgrade Package (2)
Installation order
a) Uninstall current version
• Using NICE (Notes Install Cleanup Executable)
https://www-01.ibm.com/support/docview.wss?uid=swg21459714
b) Run local cleanup
• Remove old Program- and SharedData-Dir
c) Install IBM Notes 10.0.1
d) Add French and Japanese languages (Multilingual User Interface = MUI)
e) Install Fix Pack 1
f) Install SwiftFile 4.2.1
g) Install Connections Plugins for Notes 5.5.0.20180813-1729
h) Copy customized files like stub notes.ini, ConfigFile, etc.

• Command lines for silent Uninstall and Cleanup
• Command lines for silent Install/Upgrade
• Command lines to copy customized stub notes.ini & ConfigFile

• Check the log files (created during installation) for errors for all installed
components
– Successful
– Not successful (with errors) – new installation needed after Windows restart
(complete package)

• Additional Information
– For an installation on Citrix, please check out this slideshare:
• https://www.slideshare.net/christophadler50/panagenda-webinar-virtual-faster-better-how-to-
virtualize-ibm-notesv10
– If you need/want to switch from Single to MultiUser
• Check out the MUMA Tool (Multi-User Migration Assistant) – must be done before Upgrade to
Notes 10.0.1
– https://www-01.ibm.com/support/docview.wss?uid=swg21459627
– A specific Third-Party solution can help here during Upgrade process – also if you want
to migrate the DataDir from NetworkDrive to default local → Marvel Client Upgrade ☺

• Additional Information
– Customized stub notes.ini (example)
– config.txt (example)

Define post Upgrade actions
• notes.ini changes for existing configurations
(via MarvelClient Essentials or Policy)
– Remove CREATE_R85_DATABASES=1
– Remove CREATE_R9_DATABASES=1
– Add CREATE_R10_DATABASES=1
– Add NSF_UpdateODS=1
– Add V10_WORKSPACE_BACKGROUND_MODE=1 → see next slide

IBM Notes 10.x – Workspace
• This will be controlled by a notes.ini parameter:
V10_WORKSPACE_BACKGROUND_MODE=0 → default (blue)
V10_WORKSPACE_BACKGROUND_MODE=1 → classic (grey lines)
V10_WORKSPACE_BACKGROUND_MODE=2 → customized
• If you choose for “2”, make sure you have an image resource in your local
bookmark.nsf named “$WorkspaceImage”

Test, pilot, production
• Test
– Try to use virtual machines with snapshots
– Use images, which is very close to your production configuration
▪ Desktops vs. Laptops vs. VDI
▪ ActiveDirectoy → GPOs (Group Policy Objects)
▪ No local admin user rights
▪ Enabled UAC (User Account Control)
▪ Installed AV (Anti-Virus) Software

Test, pilot, production (2)
• Pilot
– Choose the members of the pilot group wisely and let them know
– 20 – 50 users from different departments and with different requirements on IBM Notes
• Production Deployment
– Inform your ServiceDesk and your users before you push the button
– Balance your deployment by upgrading e. g. 100-500 users at the same time – no more

Virtual, Faster, Better – How To Virtualize IBM Notes V10
https://www.slideshare.net/christophadler50/panagenda-webinar-virtual-
faster-better-how-to-virtualize-ibm-notesv10

To roam or not to roam: that is the question
• Given the previous reasons why IBM Notes in virtual environments should
not have any files in the network, the following logical questions arise
– How can personal IBM Notes data folders of end users be maintained locally on the
virtual environment servers?
• Think of having N servers in the farm where personal end user data potentially
needs to be on every single server
• How do end users get their most recent IBM Notes configuration no matter
on which server in the farm they log on?
• How to ensure that disk space used by IBM Notes data folders is cleared
after log off?

To roam or not to roam: that is the question (cont.)
• How to avoid transfers of large IBM Notes data folders per user during log on and
log off which increase wait times and cause network traffic?
• The answer is: Roaming!
– To provide end users with their latest IBM Notes configuration, their data needs to be
roamed onto the server they log on to start their session
– Roaming can be achieved through own procedures (e. g. logon script),
Domino Roaming or third-party solutions

Notes Client Analysis:
How to use this data in projects

Essentials as well as MC Basic collect interesting data

Project use cases
• Hardware rollout (new laptops/workstations)
• Notes Client upgrade
• Notes Client standardization
• Location Doc standardization
• Desktop cleanup
• Certificate inventory
• ID file review
• Server consolidation
• Notes.ini hygiene

Project use cases advanced
• Introduce panagenda roaming
– Who is using which local dbs
– How big are those (especially the “system dbs”)
• Disconnected knowledge
– Which unique non system replicaids are out there
• Modernize applications
– Which apps are used as local replica
– Correlate with backend inventory
• Dislocated mailfile archives
– Correlate MC Analyze
– Homedrive scan
– Groupdrive scan

Customer use case:
Group addressbook
pernames based app on server, which can be accessed by a closed group of users
Goal: Take these applications out of service.
Question:
• Who has local replica?
• Who is using this local replica (or the app on server) to address emails
(notes.ini entry names=…)
Needed:
• Local databases
• Notes.ini entries
• List of replicaids of group addressbooks

Tableau – Sample Data Set
Live

Customer use case:
72
Citrix icons before standardization
Small amount of users in 100.000 user environment are using unmanaged Citrix
Goal: Manage Desktop and standardize page 1 and mail icon
Question:
How are Citrix Notes desktops looking today
• Which workspace pages exist
• Where are the mail icons today
Needed:
• Desktop icons
• Workspace pages

Customer use case:
74
Where are local maifile replicas?
We need do to know where users are storing/hiding local mail “backups”
Goal: Get an overview of mailreplica “archives”
Question:
• Where are mailfiles on homedrives
• Where are mailfiles on groupshares
• Where are mailfiles locally outside Notes datadir
Needed:
• Scan homedrives
• Scan groupshares
• Scan local disks

Performance

Why your Domino servers might have been using 30% more CPU
recently – and how to fix it
• A new feature added in Notes 9.0.1 FP9 (still exists in V10) called
“Delegated mail files are refreshed automatically“
– Even though the documentation states “Ask your administrator to enable this feature.”, the
functionality is turned on by default
• When an end-user opens another user’s calendar, IBM Notes will automatically add some
notes.ini entries
DELEGATED_MAIL_FILE1=Christoph Adler_server1/panagenda-demo!!mailcadler.nsf_1/31/2019
DELEGATED_NEWMAIL_SEQNUM1=7
• Impact
IBM Notes opens many different user mail files upon client startup and regularly thereafter
• Fix
Remove all DELEGATED_* entries in notes.ini
Add DEBUG_DISABLE_AUTO_REFRESH_DELEGATED_INBOX=1 to notes.ini to disable the feature

Antivirus real-time scanning in Data directory
~55% of the entire data volume in the Data
directory changes on a DAILY basis in most
setups
• 5 - 10% in Dataworkspace (up to 300 files)
• DISABLE Antivirus scanning for at least
*.ns*
*.ndk
*.xml
*.properties
*.jar
in Data Directory.
55%
45%
Data directory:
File changes per day
Once or more Less

What makes the Notes Client START slow
Client crashes/database fixups
• Especially bad for network based data directories clients
Outdated Hardware
• You need >4 GB memory if you want to use Notes AND something else
• Old fixed disks with fragmentation
• Fun Exercise: Buy a Solid State Disk and make Notes start off of that ;-)
Tons of startup programs/scripts launching during the “boot storm”
• If the disk is unable to keep up, it‘s not Notes' fault

What makes the Notes Client START slow (cont.)
Outdated Data directories
• Virtually 100% of all NTFs (Laptops: 90%) can be removed by
• Cleaning up old Notes 4+5+6/7 templates
• using ini:SharedDataDirectory= (also with Single User install!)
Operating System
• Windows 8.1 boots ~20% faster than Windows 7
• Windows 10 ~15% faster than 8.1

ODS of local databases
ODS = On Disk Structure
• ODS 16 = Notes 2
• ODS 43 = Notes 6 & 7
• ODS 51 = Notes 8.5 & 9
• ODS 52 = Notes 9.0.1
The difference between ODS 43 and 53 = up to 80% LESS FILE I/O
This helps with ANY client AND server hardware

ODS of local databases (cont.)
CAUTION: The ODS is not automatically updated when upgrading clients
– ODS 52 requires Notes >= 9.0.1 and CREATE_R9_DATABASES=1 in notes.ini for NEW db’s
– ODS 53 requires Notes >= 10 and CREATE_R10_DATABASES=1 in notes.ini for NEW db's
Good News for Notes (since 8.5.x)
– Use NSF_UpdateODS=1 with CREATE_R9/R10_DATABASES=1 for a one-time upgrade of most local
databases
• NOTE: USE WITH EXTREME CARE IF YOUR DATA DIRECTORIES ARE ON A NETWORK DRIVE!
• NOTE: End users can't access databases during compact OR databases will be ignored if in use
Manually upgrade ODS of local databases/templates
– Run the following command line:
ncompact.exe -C -ODS -* -Client -UpdateIndexes

What makes the Notes Client PERFORM slow
Again
• ODS of local databases
• Hardware
Notes.ini
• EXTMGR_ADDINS = (not just) local virus scanners
• Disable Notes “plugins“ like virus scanners etc.
– They increase Network traffic by up to 200 – 250%!
Data directory on the network vs. fixed disk
• Disk performance is the #1 bottleneck
– think SSD vs. normal HDD ; 7.200rpm vs. 5.400rpm ; network drive vs. local fixed disk

Port settings
Port settings are included in the notes.ini
• Type / Active / Encryption / Compression / Timeout
Legacy
• LAN0 / COMx / DisabledPorts → should be removed
Good idea
• Use TCPIP according to the client type
• PORTS = TCPIP
• TCPIP = TCP,0,15,0,,12320, → Desktops
• TCPIP = TCP,0,15,0,,45088, → Laptops
• TCPIP = TCP,0,15,0,,12288, → Citrix / VDI
• Hardware compression (e. g. Riverbed)?
Don‘t forget the Domino servers!

Manage Port Settings
Live

jvm.properties file
To speed up the IBM Notes JVM it’s useful to optimize memory settings
Open %ProgramFiles(x86)%IBMNotesframeworkrcpdeployjvm.properties
– Modify vmarg.Xmx from “-Xmx256m” to “-Xmx1024m”
– Modify vmarg.Xms from “-Xms64m” to “-Xms256m”
– Change vmarg.Xmca=-Xmca512k
The implicit rules
– Do not change vmarg.Xmx to more than -Xmx1024m regardless of how much memory you have
– vmarg.Xms should always be ¼ of what you changed Xmx to
Note
– The above defaults have been changed by IBM over the last couple of Notes releases.
You might find other values than Xmx256m and Xms64m in your setups.

What makes the Notes Client PERFORM slow (cont.)
IBM Roaming Users
– Try replicating 80MB each time you logon to Notes before use!
Connection documents
– Pointing to outdated server names or IP addresses
– Low priority connection documents, which can cause connectivity failures
Location documents
– IP addresses for mailserver → breaks Policies
– Outdated mail and home server information
– Outdated mail file path
– Catalog server (think db links, doc links, new bookmarks)

Why is the Catalog important?
Ever wondered what exactly happens when you click on db links / doc links / view
links
1. Notes checks whether you already have a workspace icon pointing to the replica ID in the link. If
yes, the top most icon on the stack decides on which server the db will open
2. If there's no icon on the workspace, Notes asks the catalog server in your currently selected
location document where the db is to be found. So, make sure your catalog is up to date! No
catalog server? Notes will ask your home mail server!
3. Are you replicating your catalog.nsf across all servers? Bad news: If 2.) applies, Notes will open the
database on the server it finds first in the catalog – which is sorted alphabetically. In global
infrastructures that might be a server far far away, e. g. in Asia
Make sure to use an appropriate catalog server in your location documents!

Performance Measuring with Client Clocking
NOTE:
All of this should only be done on “ONE” client – slows down client, creates huge log
files!
Use the following to see and measure client performance
– CLIENT_CLOCK=1
– CONSOLE_LOG_ENABLED=1
– Debug_Outfile=c:debug.txt
– Debug_Console=1
– DEBUG_TCP_ALL=1 (use only if needed)
Fileserver or local disk Performance Debugging is virtually impossible
– If on >= 8.5 try adding DEBUGGINGWCTENABLED=16386 in Notes

Performance Measuring with Client Clocking (cont.)
Client_Clock=1 leads to a debug file of the following format:

Performance Tuning – Understanding cache.ndk
We've all been “advised to”/guilty of deleting the cache.ndk in an effort to cure Notes
performance problems/symptoms
– Some companies even delete cache.ndk on a scheduled basis
HOWEVER, let us explain the impact of that on Notes performance ...
– Increases traffic between client and server by 4,000% (forty times more traffic, yes)
(10,000+% if the data directory is on a network drive)
– The more databases end users use, the worse it gets
– There is always a root cause – deleting cache.ndk only fixes symptoms
– Let's look at some detailed traffic analysis for just ONE application (the mail file) of ONE user ...

Performance Tuning – Understanding cache.ndk (cont.)
100 users =
150 MB vs. 3,7 MB
1000 users =
1.5 GB vs. 37 MB
Excluding Fileservers!
