Why not just Sametime Standard ?Why not just Sametime Standard ?


Sametime AdvancedSametime 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


Persistent Group Chat RoomsPersistent Group Chat Rooms


Sametime AdvancedSametime 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


Sametime AdvancedSametime 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


ST Gateway Technical ArchitectureST Gateway Technical Architecture• LDAP Server (required for ST, recommended for ST Gateway)• Domino Server running Sametime Standard• WebSphere Application Server• DB2 Server


ST Gateway Technical ArchitectureST Gateway Technical Architecture• Single Server Deployment

– NAT is NOT supported– Users do not need to see the Sametime Gateway


ST Gateway Technical ArchitectureST Gateway Technical Architecture• Clustered Environment

– NAT is supported in clustered environments– SIP Proxy Server and XMPP server


• “n” Domino servers running Sametime Standard• WebSphere Application Server• DB2 Server• LDAP• IBM HTTP Server (Best Practice)

Sametime EMS Technical ArchitectureSametime EMS Technical Architecture


• Cluster Web Meetings– Failover– Load Balancing– Please note there is not geographic independence (ST EMS

decides your target room server no matter your location)

Performance Tips and Best PracticesPerformance Tips and Best Practices

Community Services (chat)Community Services (chat)


Sametime DatabasesSametime 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)


Home Sametime ServerHome 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


Use FQHNUse FQHN• FQHN – Fully Qualified Host Names

– sametime.domain.com vs 192.168.1.1

• Required to use the Sametime Web Admin tool

• Single Sign-On transactions need FQHN


Increasing Chat CapacityIncreasing 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.


Increasing Chat CapacityIncreasing Chat Capacity

• Up to 10,000 users using standard connectivity


Increasing Chat CapacityIncreasing Chat Capacity

• Up to 20,000 users for each Multiplexer• 100,000 if using 5 Multiplexer (do the math !)


Regional ST MUX – Single ST ServerRegional ST MUX – Single ST Server


LDAP authentication / search filterLDAP 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*))))


Sametime.ini – LDAPSametime.ini – LDAPST_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_INTERVALThis 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_LOWThis 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_MAXThis 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_INTERVALThis 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_RESULTSMaximum number of entries that may be returned in a single search when searching for people or groups. Default is 1000.

Reload directory tablesReload directory tables• Change search for new users and servers to 12 hrs for users

and 24 hrs for servers (evaluate your requirements)


Loopback Cluster document – Community ClustersLoopback 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


Make Sametime not Case Sensitive Make Sametime not Case Sensitive (3(3rdrd Products) 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;”


Sametime Policies – Use them !Sametime Policies – Use them !


Performance Tips and Best PracticesPerformance Tips and Best Practices

Web ConferencingWeb Conferencing


STConf.nsfSTConf.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


Multiple Sametime ServersMultiple 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.


Invited Sametime ServersInvited Sametime Servers


Connecting ST Meeting ServersConnecting ST Meeting Servers• Go to Configuration > Connectivity > Servers• Add new Sametime Meeting servers


Scheduling a New MeetingScheduling a New Meeting


HTTP Tunneling vs Standard AccessHTTP 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.• For a full list of ports used by Sametime go to:

– http://www-01.ibm.com/support/docview.wss?uid=swg21097949


Screen Size and ResolutionScreen Size and Resolution• 8 Bits• Lower screen resolution for the Web Meeting if sharing your

screen


Win2003 Scalable Networking PackWin2003 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.• IBM Technote: 1295167

• http://www-01.ibm.com/support/docview.wss?rs=899&uid=swg21295167


Useful Sametime.ini variablesUseful Sametime.ini variables

• MeetingStartEarlyMinutes=<integer>

• STScheduleLimitDays =<integer>


Sametime 8.5 – What to expect (From the Sametime Sametime 8.5 – What to expect (From the Sametime Blog)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
