  • In this benchmark, DNA calcules the number of active users as a percentage of the number of person documents registered in the Domino directories of the customer. User are considered active as soon as the user has had at least one user session towards one of the servers in scope, with a rich client, during the 7 days of analysis. Web users are not included in this DNA analysis. Purpose of this slide: If the result is low this could indicate that only a small number of servers have been placed in scope for this analysis. When all servers were included, a low score might indicate that the directories containt person documents that are no longer in use.
  • This benchmark looks at the amount of time notes clients spent online with the Domino servers. The analysis is split up into two measures: 1. total time online during the 7 day period, expressed in hours; 2. average session duration expressed in minutes; Average session duration has a negative correlation with network bandwidth consumption. The longer an average session lasts, the lower the network consumption. High session duration may indicate performance issues in the network or at the servers. Notice that with the customer on the right, each user had sessions open to separate mail and application servers. This is why the customer scored a total online time of more than 40 hours. Usually, we see that customer who deploy local mail file replicas (where users do not work on server but on their local replica) score significantly lower in session duration, and at higher network bandwidth consumption.
  • Another method to profile end user demand (user segmentation) is by taking a look at the distinct number of working hours per day that users show active on the server park. This analysis does not show the working hours of end users, but observes how many distinct hours the user showed activity, on average per day. As an example: remote non-office workers (e.g. salesmen visiting customers all day) typically replicate with their home server in the morning (1 hour observed), go on the road all day and replicate again in the evening (another hour observed). Many system accounts (monitoring workstations, fax machines operating with notes) show activity up to 24x7. This chart expresses the percentage of the total number of active users in each category.
  • This analysis presents an overview of the overall user demand characteristics. Total demand is expressed in 6 columns, with each column representing 100% of that type of demand scored during the week of analysis. Each column is then split up into various types of demand: Checks for new mail shows Notes clients checking for new mail; System dbs represents access to system databases; Mail files: access to end user mail files; Directories: access to Domino Directories; Applications: access to application databases* Application databases are identified as follows: Of all databases inventoried, DNA substracts mail and mailin files, ‘known’ system databases and domino directories. What remains is a set of databases that are considered applications. Although this is not a 100% accurate method, it does provide a solid understanding of the types of user demand.

What remains is a set of databases that are considered applications. Although this is not a 100% accurate method, it does provide a solid understanding of the types of user demand.
  • This analysis is revealing how end users make use of Notes databases, in terms of network traffic. Every bubble on this chart represents a database. Databases have different colors, indicating the type of database. The size of each bubble is defined by the distinct number of end users that showed activity during the 7 day period that was analyzed. The horizontal and vertical distribution of bubbles reflect the amount of network traffic (bytes read and written towards each database, logarithmic scale). Databases in the lower left corner are the most light in terms of network consumption, while databases in the upper right hand are the most network intensive. While this analysis presents up to 10,000 most used databases, the underlaying factsheet does contain all databases that have been touched. Trust Factory is offering an optional cluster plotter component that enables customers to generate a wide variety of angles in analyzing database utilization.
  • A significant optimization potential can be found by analyzing user accounts that show excessive demand patterns. Often, we see that very few user accounts consume one third or more of the total network and server capacity. DNA is able to classify user accounts by means of comparing their individual behavior with the organization average. While the underlaying algorhitm is rather complex, it basically comes down to the following classification: Light: below or on average with the overall average; Moderate: causing a load that is 10 - 100 times more than the average; Intensive: causing a load that is 100 – 1,000 times more heavy than average; Extreme: causing a load that is more than 1,000 times more heavy. For each class of user account, this chart shows their impact on the total user demand caused in the 7 days analyzed. This total demand is expressed in 6 measures. The numbers behind the legend indicate the number of users in that class. Details for the 10 most heavy accounts are given in the next slide.
  • This slide gives an indication of over capacity in the server park. Each server is classified according to the maximum number of concurrent end user sessions it has served, over the 7 day analysis period. Load levels on servers in the yellow area are very low and can often be redistributed onto other servers. Functional servers (smtp, hubs, blackberry, sametime) often show very low session levels. Use the factsheet to verify which servers fall in each category. Customers with a highly centralized server park often show less over capacity than customers with a very decentralized server park.
  • This analysis topic reveals the total session concurrency caused by end users working on Domino servers, in each of the 168 hours (7 days) that were analyzed. For time-series charts, the timezone reflected on the horizontal axis is equal to that of the workstation that was used for the data collection.
  • Network compression is a feature that was introduced with Lotus Notes and Domino release 6. The compression ratio we see at customers is around 40%, so the benefits of this feature are significant. For network compression to function properly, a setting needs to be in place at both ends of the connection, so both on all servers as well as on every desktop. This is usually not the case. With this analysis, we show how much of the total network traffic was making use of compression (pie chart). In addition, DNA is presenting for all servers and users if compression has been enabled or not. Customers that make use of other compression solutions in their network, may want to reverse the purpose of this analysis. In these situations, customers may want to disable Notes network compression. The factsheet reveal which servers and users make use of compression.

    • 4. IBM Notes and Domino @ Nationwide The Nationwide Notes/Domino Environment – Production use began in 1997 with version 3.3 – Migrated/Consolidated to Notes from cc:Mail and a variety of different mainframe email systems – Current environment • 6 Domino Domains • 200+ Domino servers on Microsoft Windows® (8.x mixture – mostly 8.5.3 for mail) (Mail, Management, Application, Blackberry and Good servers) • Active / Passive clustering accross two data centers • 56,000+ Notes clients (mostly 8.5.2) • 15,000,000+ messages routed weekly • ~20 Sametime 8.5.2 IFR1 servers using Domino and WebSphere • ~1200-1400 Domino applications with 700 being active4
    • 5. IBM Notes and Domino @ Nationwide What is Nationwide trying to accomplish by performing this in-depth analysis? – Server: • Discover inconsistant configurations, and find gaps where Domino does not readily report items that could potentially turn into problems. – Client: • Discover and inventory client side settings, configurations and local databases to get a better understanding of client health and functionality. – Environmental: • Combine server and client findings to get a holostic view of our Notes/Domino environment.5
    • 6. What we didCollect data from Inventory Notes clients Domino servers – notes.ini – statrep.nsf – desktop, bookmarks, – log.nsf names – catalog.nsf – local databases – directories (names.nsf, – various OS and Notes DA) properties Talk 6

    • 21. And now for the client-side analysis …21
    • 22. Diving right into client-side analysis The following slides dive into various client-side details In many cases, the Nationwide environment is surprisingly clean – Your environment will most probably look very different22
    • 23. Notes 8.0.2 & 8.5.2 Although there are 1,817 clients with 8.0.2, only 26 have Create_R8_Databases enabled = they do not leverage the benefits of ODS 4823
    • 24. Operating system details Various different client-side operating systems in use:24
    • 25. Local replicas of public addressbook Local replicas of the public addressbook beyond cutoff Risk of replicating deleted documents back into server-side replica  Enable PIRC:25
    • 26. Local addressbooks:Version mismatch Checked rows show configurations where names design matches client version – (might still have wrong ODS, though) In general, design mismatch of system databases – slows down client startup and beyond – causes unexpected behaviour or non-functioning of Policies  can be fixed by – making sure clients have correct templates – removing TemplateSetup= from notes.ini26
    • 27. Local bookmark.nsfs:Version mismatch Checked rows show configurations where bookmark design matches client version – (might still have wrong ODS, though)27
    • 28. Local cache.ndk:Version mismatch Checked rows show configurations where cache design does NOT match client version – (might still have wrong ODS, though) Cache.ndk must be deleted and re-created together with CREATE_R85_DATABASES=1 in notes.ini - for it to have proper design and ODS (make sure client has correct cache.ntf)28
    • 29. Local desktop.ndk:ODS issues Checked rows show configurations where desktop ODS is NOT ideal29
    • 30. Local log.nsfs:Version mismatch Checked rows show configurations where log design does NOT match client version – (might still have wrong ODS, though)30
    • 31. Notes.ini:Log= A couple of users have multiple log= lines in notes.ini Since only the first entry is actually read in such a case, logging does not work as expected for those users31
    • 32. More on ODS levels Various databases and templates do not have an ideal ODS …: Adding CREATE_R85_DATABASES=1 and NSF_UpdateODS=1 to notes.ini can help!32
    • 33. More notes.ini entries … Less than 1% of all users have port compression disabled, but 25% of all traffic is uncompressed  must be enabled on BOTH servers and clients  identify servers that are used by users but have port compression disabled33
    • 34. EXTMGR_ADDINS= … Various users have EXTMGR_ADDINS entries in notes.ini which are seperated by a blank  surprisingly DOES work (side-effects unknown)34
    • 35. Mail Who encrypts email when saving emails? Who encrypts sent email? Who signs sent emails?35
    • 36. Calendar Users with wrong(?) calendar settings? 1=Sunday 2=Monday 3=Tuesday 5=Thursday36
    • 37. Cache.ndk Users where Cache= in notes.ini points to – A dedicated file/path – Partly filepaths in which users might not have write permissions (e.g. Notes program files directory)37
    • 38. Clustering / Loadbalancing FailoverSilent (defaults to 0) is disabled for almost all users:38
    • 39. Client Configuration Health Basic vs. Standard clients Clients with wrong InstallMode= setting in notes.ini39
    • 40. … same for ini:InstallType= Identifying Client/Admin/Designer configurations:40
    • 41. Hardware/OS details: disk space Users with too little free disk space – might soon call helpdesk – may experience stability issues – have high disk fragmentation = slooooow41
    • 42. Hardware/OS details: memory Users with too little memory – again, sloooow(er) client experience42
    • 43. Locations: do not use IP addresses as mailserver names … A couple of users have an IP address configured as their mailserver breaks Policies DNS names as mailservers could become a problem if the DNS domain were ever to be renamed …43
    • 44. Mailfile replicas? 98 users work off a local replica +330 managed replica users BUT: 3,407 users have a local replica and: 149 users have more than one mail replica … – 39 of these local replicas are beyond cutoff:44
    • 45. ECL Open doors 45
    • 46. Analyzing desktop icons (special vs. local vs. server)46
    • 47. Analyzing desktop icons (details) 196,930 local databases with an icon (e.g. bookmark.nsf) 380,243 local databases without an icon (e.g. help files, cache.ndk, …) 1,266 templates on desktops 37,108 templates not on desktops (think shared data directory) 36,865 replicas without any icon 267 replicas without a local icon 2,686 replicas without a server icon 862,395 template replicas without any icon 14 template replicas without a local icon 765 template replicas without a server icon47
    • 48. Summing it up …48
    • 49. Conclusions Mission accomplished – Provided a holistic view across servers and clients Mission not accomplished (yet) – This is work in process Nationwide is the 1st customer out of many that leverages most of the features/potentials of the N/D 8.5 platform – Optimization potential almost exclusively in areas “without features” – Implemented Domino password security the way it should be49
    • 50. What we learned Detailed data helps to leverage IBM Notes and Domino to its fullest potential … and helps shifting from reactive to proactive  Assumptions vs. Evidence – Eliminate best guess/hope based working Find out and focus on what really matters50
