  • iNotes 9.0 Support Information• Browser & Operating System Support Microsoft Windows ® ® Apple Macintosh ® ® Linux® XP Pro, Vista, 7 Win 8 OS 10.7, 10.8 ® RHED 6 Ubuntu 12 ® Internet Explorer ® Safari 10.0, 9.0, 8.0 6.0 Firefox ® Firefox ® Firefox ® 17 ESR or greater 17 ESR or greater 17 ESR or greater Chrome ® Chrome ® Chrome ® 24 or greater 24 or greater 24 or greaterFirefox and Chrome are rapidly releasing new versions. iNotes statement on rapid browser releases: ● Due to the increased rate at which vendors are now releasing new versions of their browsers, support for browser updates will only be maintained for the most recent shipping release of iNotes. iNotes product testing on new browser versions will continue at periodic intervals which may or may not align with the browser vendors release schedule. Should a problem be found when using a browser update with the most recent release of iNotes, we will make every effort to resolve the issue. To expedite this resolution it is our recommendation that you contact the browser vendor as well as IBM Support about the situation. 16
  • IBM Connections Mail“Being in mail without being in mail”• Lightweight social messaging tool• Provides simple, elegant Web mail and calendar experience allowing people to remain within IBM Connections• Quickly manage incoming mail without leaving your social context• Make informed decisions in real-time with a social approach that brings information and expertise into easy and immediate reach• Delivered as a plug-in to IBM Connections 4.0 17
  • What Well Cover• Trends driving move to browsers• Client considerations• Application considerations• Server considerations• Wrap-up 18
  • Application Considerations• XPages• Notes Browser Plug-in for Windows 19
  • Modernize with XPages • XPages – Web 2.0 framework ● Use industry standard Web development skills (HTML, CSS, and JavaScript) ● Java-based framework facilitates reuse of Java libraries ● One model for Web, Rich Client and Mobile • Extend the reach of your Notes/Domino applications ● Web browser ● Mobile Web access ● WebSphere Portal and Connections using iWidgets / OpenSocial Gadgets / Embedded Experience • Notes/Domino apps → Social business apps ● Integrate Connections and other social application services (e.g., Facebook, Twitter, Dropbox, etc.) into XPages applications ● Integrate Domino data and services into social business framework – XPages as OpenSocial gadgets → Embedded Experience – Support for Activity Streams – Secured with SAML/OAuth • Key decision criteria ● Mobile Web access ● Integration with other OpenSocial container apps 20
  • Notes Browser Plug-In for Windows• Designed to easily extend applications previously available only to Notes users out to Web browser as well• Allows applications to run in a browser with no design modification!• Designed to be similar to other popular browser plug-ins in size, deployment, and configuration needs• Uses iNotes message composition screens on forwards• Copy and paste document links (and copy as table) from Notes application into Web editors• Icons added to iNotes and Notes Browser Plug-in to easily switch between• Minimal limitations ● Windows only ● Firefox, Internet Explorer 21

  • What Well Cover• Trends driving move to browsers• Client considerations• Application considerations• Server considerations• Wrap-up 25
  • Server Considerations• Admin considerations• Optimizing for performance• Secure deployment considerations 26
  • Enabling iNotes Check List• Enable HTTP on your Domino Servers• Use Standard Mail8 (Mail8.ntf) or later Notes Mail Template• Enable iNote Redirector Application• Enable SSO with your other IBM Applications and Clustered Domino Servers• Enable SSL for security between Domino and client browsers• Deployment Considerations ● Reverse Proxies ● SSL VPNs ● Web Load Balancer ● Integration with Sametime / Files / Quickr ● External Access ● Local Content → iNotes – Contacts – Notebook 27
  • Optimizing iNotes Performance • Need to reflect the change in architecture from client/server to browser ● Understand where & how the work takes place – E.g., Notes is able to keep some internal Notes DB structures (like view indexes) open for an extended period of time – Check client browser settings, especially caching & security • Upgrade to Domino 9.0 if running an older server release! ● Significant CPU & disk I/O savings can be had • Check server peak CPU usage ● Dont extrapolate from one data point to infinity – Ensure an apples-to-apples comparison – Don’t double/triple current Domino CPU. CPU from user interaction is only a fraction. I.e., You may have 25% CPU peaks, but only 5% is user triggered, so 2-3x would be 10-15%. ● Server may be under-utilized and handle increased load • Add CPU to upgradeable multi-CPU systems and virtual systems ● Keeps server count equal and administration costs equal 28
  • Optimizing iNotes Delivery • Load balance mail files in a cluster ● Reverse proxy or load balancer (sprayer) ● Move subset of users to machine with more CPU ● Client session failover ● Server maintenance flexibility • Web appliances for application acceleration ● Cache Web content ● Boost client performance and reduce load on Domino server • Offload expensive http activity to common Web infrastructure ● Move SSL and/or compression to a dedicated device • Relatively small up-front costs to enable iNotes ● Bandwidth and storage is approximately 1 to 1 (Notes to iNotes) ● Possible up-front CPU cost, a small part of the email cost model ● Possible Web load balancer cost 29
  • Secure Access Outside the Firewall• Virtual Private Network – VPN ● Helps provide network level of security to only allow authorized users in• Reverse Proxy ● Helps provide High Availability as well as Load Balancing• SSL VPN ● Secure Sockets Layer – SSL – Help provides security from packet sniffers by encrypting data over the network ● Helps provide access control for mobile device users outside the firewall 30
