Let’s start with… Sametime is not just for Lotus/Domino Platforms Supported LDAP Server or Active Directory as LDAP Sametime Toolbar for MS Outlook Who is not using Sametime now ? Who is using Sametime Entry ? … Sametime Standard ? … Sametime EMS ? … Sametime Advanced ? … Sametime Gateway ? © 2005 PSC Group, LLC

Sametime Advanced Persistent Group Chat Rooms Users can create, enter, and read/contribute to ongoing chats at any time Users can be alerted to new content, events, and people in the chat room Users can participate from the Lotus Sametime Connect client or a browser Persistent Chat Rooms can be linked to Broadcast Channels © 2005 PSC Group, LLC

Sametime Advanced Real-time Broadcast Channels Broadcast Announcements: Real-time alerts can be sent to channel subscribers Instant Poll: subscribers can create and respond to real-time polls Skill Tap: subscribers can find and interact with experts; expert responses can be saved and retrieved Broadcast Chat: invite members of a broadcast community to an online group conversation © 2005 PSC Group, LLC

Sametime Advanced Location services Server-stored locations Ability to see the last time and location from which an offline colleague was last online Instant Share: share or remotely control a computer screen with colleagues © 2005 PSC Group, LLC

Ports requirements 1516, 1503 and 1352 for Server to Server 80, 443(if https is enabled), 554,1533, 8081, 8082 See IBM Technote for complete details http://www-1.ibm.com/support/docview.wss?uid=swg21097949 © 2005 PSC Group, LLC

Sametime Databases VPUserInfo.nsf – User Information (Buddy Lists) and Privacy Lists STConf.nsf – (Web Meetings Info) STConfig.nsf – Sametime Configuration Database STAuthS.nsf – Secret (Still Available but used mostly in old releases) STAuthT.nsf – Tokens (Still Available but used mostly in old releases) © 2005 PSC Group, LLC

Home Sametime Server Should be used when multiple Sametime servers are deployed Awareness is kept in the Home server Buddy List is kept in the Home server Use the cluster name if ST Community Services are clustered © 2005 PSC Group, LLC

Increasing Chat Capacity Sametime Multiplexer The Sametime Connect clients connect to the Community Services multiplexer computer, not the Sametime server. This configuration frees the Sametime server from the burden of managing the live client connections; the multiplexer machine is dedicated to this task. The Community Services multiplexer maintains a single IP connection to each Sametime server in the cluster. © 2005 PSC Group, LLC

LDAP authentication / search filter Set Standards…Users don’t really need to login using first name, last name, short name, email address, common name, etc…. (&(objectclass=organizationalPerson)(|(cn=%s*)(givenname=%s*)(sn=%s*) (uid=%s*)(mail=%s*)(notesmail=%s*))) vs (&(objectclass=organizationalPerson)(|(notesmail=%s*)(uid=%s*)(mail=%s*)))) © 2005 PSC Group, LLC

Sametime.ini – LDAP ST_DB_LDAP_CONNECTIONS_NUMBER This parameter increases the number of connections from the Sametime server to the LDAP server(s) specified in stconfig.nsf. The default setting is set to one (1) connection. This setting should never be changed. ST_DB_LDAP_KEEPALIVE_INTERVAL This parameter defines the duration (in minutes) to wait between keep-alive messages that are sent on idle LDAP connections. 0 means no keep-alive. A keep alive will only be sent when a respray is not scheduled for that minute. ST_DB_LDAP_PENDING_LOW This parameter defines the maximum number of requests that can be in flight on the network to the LDAP server before we send out new requests to the LDAP server ST_DB_LDAP_PENDING_MAX This parameter defines the total maximum number of requests that can be sent to the LDAP server. After reaching the number specified by ST_DB_LDAP_PENDING_LOW, the Sametime server will send out requests until this value is reached. After reaching this value, the Sametime server will wait for responses from the LDAP server. ST_DB_LDAP_RESPRAY_INTERVAL This parameter will define how often (in minutes) the connection to the LDAP server should be dropped and then re-established. This parameter is very important in load balanced or rotating DNS scenarios, as it allows the Sametime server to drop the current connection instead of continuously trying to connect to a non-responsive LDAP server. ST_DB_LDAP_MAX_RESULTS Maximum number of entries that may be returned in a single search when searching for people or groups. Default is 1000. © 2005 PSC Group, LLC

Sametime.ini - LDAP [Directory] ST_DB_LDAP_CONNECTIONS_NUMBER=1 ST_DB_LDAP_KEEPALIVE_INTERVAL=1 ST_DB_LDAP_PENDING_LOW=30 ST_DB_LDAP_PENDING_MAX=60 ST_DB_LDAP_RESPRAY_INTERVAL=5 ST_DB_LDAP_MAX_RESULTS=100 © 2005 PSC Group, LLC

Loopback Cluster document – Community Clusters A cluster document that includes only the server it resides on and is used to redirect connections to itself. Sametime Meetings will use local community services http://www-01.ibm.com/support/docview.wss?rs=477&uid=swg21196034 © 2005 PSC Group, LLC

Make Sametime not Case Sensitive (3 rd Products) If Update Status fails….(I am available, Do not disturb, I am away) Sametime resolve =>> uid=lguiriga,cn=users,dc=psc,dc=com Quickr sends =>> UID=lguiriga,CN=users,DC=psc,DC=com Update Sametime.ini Add AWARENESS_CASE_SENSITIVE=0 under [Config] Append -DAWARENESS_CASE_SENSITIVE=0 to the STLINKS_VM_ARGS under [STLINKS] Update stlinks.js Using a text editor set “var STlinksCaseSensitive=false;” © 2005 PSC Group, LLC

STConf.nsf Keep it small Compact –B only Don’t use –D or -R Remove old Meeting documents if possible Enable PurgeMeetings in STConf.nsf Set STPurgeMeetingPastDays=“n days” Create a selective replica to another Domino server for archiving © 2005 PSC Group, LLC

Multiple Sametime Servers Spread the load of a large user population among multiple servers. Reduce network usage and improve server performance when you have significant user populations in remote or distributed locations. Securely extend meetings conducted on a Sametime server inside your network firewall to a Sametime server deployed outside the firewall in your network DMZ. This arrangement allows Internet users to participate in meetings with users on your corporate intranet without compromising network security. © 2005 PSC Group, LLC

HTTP Tunneling vs Standard Access HTTP Tunneling uses port 80 to access all Sametime features Be aware ! Sametime always tries to use standard connectivity even if HTTP Tunneling is enabled HTTP Tunneling should be used as a last resource for Web Conferencing.

Win2003 Scalable Networking Pack Sametime client log-ins (Sametime Connect client, Sametime meeting room client, STLinks applications) are intermittently taking up to ten minutes to complete. Sametime chat windows are opening slowly when attempting to chat with another user. Meeting components are slow (can be refreshing pages or whiteboard). In the sametime.log, Stmux reports that it is full. Application sharing and screen sharing appear slow or appear to hang. Web pages are loading slowly.

Sametime 8.5 – What to expect (From the Sametime Blog) A new online Meeting experience A zero-download, browser-based instant messaging client. Great news for resource constrained deployments and chat enabling web sites. The ability to extend unified communications capabilities to your web apps through standard web development tools (CEBP) A modern video infrastructure with higher-quality, lower bandwidth codecs and improved integration into standards-based SIP endpoints New mobile device support, including a browser-based iPhone client A new centralized management console. This will make it easier for IT to deploy and administer Sametime. An optional Sametime Meeting Client (Sametime Meeting Plug-in) for Sametime Client users © 2005 PSC Group, LLC
