11. High Availability as per today (and maybe in
the future)
§ Traveler supports mail file clusters (info is stored in dedicated
ntsclcache.nsf)
§ But is doesn’t support “real” high availability. There are several
workarounds:
§ Run Traveler on a high available virtual machine platform (but
please, without snapshots)
§ Run a dedicated, ready-configured hot-stand-by system
§ Quickly install Domino and Traveler from the ground up ;-)

13. Lotus Traveler 8.5.3 Upgrade Pack 1
§ What’s an “Upgrade Pack”?
§ An “Upgrade Pack” is a new IBM way (besides major/minor
releases, FP’s and HP’s) to deliver additional functionality.
§ Why an “Upgrade Pack”?
§ It’s a way to roll out major new functionality outside a major
release.
§ It contains a lot more than “only” high availability…
13

14. Lotus Traveler 8.5.3 Upgrade Pack 1
- Contents (excerpt)
§ High availability
§ Scaling with “Traveler-Server-Pooling”
§ Support for a single server URL
§ Client version management
§ XPages administration interface
§ Additional Android settings
§ Additional filter settings
14

15. Lotus Traveler 8.5.3 Upgrade Pack 1
- Requirements
§ Domino 8.5.3 (Windows or Linux)
§ 64bit for the operating system is a requirement when running
High Availability!
§ IBM Lotus Domino 8.5.3 Upgrade Pack 1 (which is included in the
Traveler installation image and will be installed automatically if not
present)
§ IBM DB2 9.7.0.5 or Microsoft SQL 2008 Server (if you want to use
High Availability)
§ An IBM DB2 entitlement is contained free of charge for this. But
the Traveler servers need to be licensed as Enterprise servers! 15

16. Lotus Traveler 8.5.3 Upgrade Pack 1
- change of configuration settings location
§ All configuration parameters will move from the NTSConfig.xml to the
notes.ini.
§ Benefit: update installation won’t overwrite configuration changes.
Please use – as a best practice – server configuration documents.
§ Old (NTSConfig.xml)
<COMPONENT COMPONENT_TYPE="TrueSyncServer">
<PROPERTY NAME=”Lookup_Min_Length" VALUE=3 />
§ New (notes.ini)
NTS_LOOKUP_MIN_LENGTH=3
16

17. Lotus Traveler 8.5.3 Upgrade Pack 1
- change of Traveler URI
§ The Traveler URI will change
§ Old: https://traveler.midpoints.de/servlet/traveler
§ New: https://traveler.midpoints.de/traveler
§ The installation automatically creates a HTTP redirect from “/servlet/
traveler” to “/traveler”, so that existing connections still will work.
§ If you run Mobile Device Management => consider to change the
URI.
17

18. Lotus Traveler 8.5.3 Upgrade Pack 1
- managing sent mails
§ New configuration setting “NTS_SENDMAIL_SAVE_OPTIONS” which
defines if sent mails should be stored in the mail file.
§ user (== default)
sent mail will be saved if defined in the mail files calendar profile
§ never
As the value says…sent mail won’t be saved
§ always
Again as the value says…sent mail will always be saved
§ noatt
Very cool => attachments won’t be saved, can be i. e. combined
with “always” (NTS_SENDMAIL_SAVE_OPTIONS=always,noatt)
18

19. Lotus Traveler 8.5.3 Upgrade Pack 1
- managing the outbox server
§ As per today mails are sent via the users mail server. Those servers
often don‘t run an AntiVirus solution. That may result in insecure mail
(from the mobile devices).
§ The new configuration setting „NTS_OUTBOX_SERVERS“ allows to
define the mail servers (failover like) which will be used for sending
outgoing mail.
§ NTS_OUTBOX_SERVERS=Gateway1/srv/midpoints, Gateway2/
srv/midpoints
19

20. Lotus Traveler 8.5.3 Upgrade Pack 1
- extended Notes doc link handling
§ Notes doc links are now converted into HTTP links (as you know it
from iNotes).
§ Restrictions
§ The target server must be reachable via HTTP.
§ The target application should be web enabled.
20

21. Lotus Traveler 8.5.3 Upgrade Pack 1
- web based administration interface (I)
§ With this release IBM introduces the administration from a „classic“
Notes usage to a XPage based administration interface (for
standalone and HA servers).
§ The „classic“ Notes interface should be considered as
deprecated.
§ Now you can administrate your Traveler environment from
everywhere...
§ ...but watch out! The administrators shouldn‘t have weak HTTP
passwords!

26. Lotus Traveler 8.5.3 Upgrade Pack 1
- web based administration interface (VI)
26

27. Lotus Traveler 8.5.3 Upgrade Pack 1
- Client Download Manager (I)
§ The new Client Download Manager allows a dedicated management of
Lotus Traveler mobile clients based on operating system and version
number.
§ The installation files are now stored in the SQL database! That allows to
use the same clients for multiple servers with HA.
§ The installation files are saved from the SQL database onto the local
file system (for HTTP download). The files are located within
„<dominodata>/domino/html/travelerclients“.
§ A file change in the SQL database automatically changes the file on the
file system. 27

28. Lotus Traveler 8.5.3 Upgrade Pack 1
- Client Download Manager (II)
28

29. Lotus Traveler 8.5.3 Upgrade Pack 1
- Client Download Manager (III)
§ Updating / new installation of Traveler automatically updates the clients
and assigns them as default.
§ That‘s not applicable for HA – there the default assignment happens
after all servers have been updated.
§ You‘re able to assign different clients to different users/groups, i .e.
for testing purposes.
29

30. Lotus Traveler 8.5.3 Upgrade Pack 1

35. Lotus Traveler 8.5.3 Upgrade Pack 1
- different run modes
§ Run Traveler standalone (as you know it)
§ LotusTraveler.nsf
§ Local Derby database per Traveler server
§ Run Traveler high available (HA)
§ Traveler-“Pool”
§ Remote SQL database server
35

36. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability and Loadbalancing
§ If you want to use HA, you‘ll have to implement a SQL system for
storing the data (which replaces the local Derby database as a
storage).
§ Currently supported enterprise relational database systems
(additional RDBMS being considered for a future release):
§ IBM DB2 Server 9.7.0.5 or higher
§ Microsoft SQL 2008 Server or higher
§ Please use the HA products lines of those RDBMS!
36

37. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability and Loadbalancing
37

38. Lotus Traveler 8.5.3 Upgrade Pack 1
- Load Balancer / Reverse Proxy
§ A load balancer is a hard- or software appliance, which allows high
available networking connections.
§ Virtual IP address for multiple backend servers (i. e. Cisco Local
Director, IBM Websphere Edge Server)
§ A (secure == https) Reverse Proxy serves as authentication and
redirection frontend.
§ Sends requests from the same connection to the same backend
system.
§ Systems could be Lotus Mobile Connect (my preferred choice),
IBM Tivoli Access Manager, F5 Big-IP, Apache Pound...
38

39. Lotus Traveler 8.5.3 Upgrade Pack 1
- Traveler service pools
§ Traveler servers are „pooled“ in HA
§ All members of the pool use the same backend SQL database.
§ Each server in the pool can manage each user.
§ Every member serves HTTP requests.
39

40. Lotus Traveler 8.5.3 Upgrade Pack 1
- Traveler service pools
§ The requested Traveler server may serve the current request or
delegate it to another member in the service pool.
§ A delegations depends on several factors, i. e. which server is
currently monitoring the users mail database or how server usage is.
§ All servers are communicating within the pool on TCP port 50125 for
determining that. The communication could be encrypted (optional).

§ It‘s so easy...it‘s Traveler.
§ Run the standard Traveler installation
§ Validate the installation
§ Create the SQL database on the SQL server (IBM DB2 is used here)
§ Create the table structure and the permissions for the SQL database
§ Add the first Traveler server to High Availability (initiates the service
pool)
§ (optional) Add additional Traveler servers to the existing service pool
42

43. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (I)
§ Run the standard Traveler installation
§ Like in previous releases. Creates a ready standalone Traveler
server which uses the local Derby database.

44. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (III)
§ Validate the installation
§ It‘s quite simple. Just start the Domino with Traveler and take a
look at the version.
§ Additionally: Traveler 8.5.3 UP1 uses – new in this release – the
built-in OSGi servlet container and no longer the old Domino
servlet engine.
You can check the installation on the console.

[122C:0002-13C4] 05.06.2012 14:26:45 No unresolved constraints.
44

45. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (IV)
§ Create the SQL database on the SQL server (IBM DB2 is used here,
you need to do it once)
§ Traveler allows to create the database scheme automatically.
That‘s the preferred way. Otherwise you may setup it manually
per SQL script (DDL).
§ You can configure it using the notes.ini parameter
NTS_AUTO_DBSCHEMA=false/true
45

46. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (V)
§ AUTOMATIC: create the new SQL database using the DB2 cc.
Traveler populates it automagically at startup.
46

47. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (VI)
§ MANUAL: create the new SQL database per script.
Traveler populates it automagically at startup.
§ Extract <dominodata>/traveler/cfg/db/TravelerSQL.zip
§ Goto the sub directory DB2
§ Change the db2cmd script if needed
§ Execute
db2cmd –c –w –i db2 –tvf createDb.sql -o –r createDb.out
§ Execute
db2cmd –c –w –i db2 –tvf appGrants.sql -o –r appGrants.out
47

48. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (VII)
§ Add the first Traveler server to High Availability
§ Copy the JDBC driver
from: <db2_install_dir>/sqllib/java/db2jcc4.jar
to: <domino>/traveler/lib
§ Open a shell and goto <dominodata>/traveler/util
§ Execute the travelerUtil tool
travelerutil db set url=jdbc:db2://db2.midpoints.net:50000/traveler
user=db2admin pw=passw0rd
§ The credentials will be saved encrypted whithin the
LotusTraveler.nsf.
48

49. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability installation (VIII)
§ Start the Domino server. Done!
49

50. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability administration (I)
§ You can issue console commands on any Traveler server for any
Traveler server.
§ A Traveler server could be deactivated for user acces.
§ You can bind users to a specific Traveler instance.
50

51. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability administration (II)
§ tell traveler bind options
§ Binds a user to a specific server. This will disable failover for this
user.
§ Tell traveler HADR show
§ Shows the state of all servers in the pool.
51

52. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability administration (III)
§ tell traveler users
§ Shows all users of the specific server.
§ tell traveler available <on/off>
§ Enables/disables pool participation of this server. No new users
will be added if a server is disabled (but existing users are still
connected).
52

53. Lotus Traveler 8.5.3 Upgrade Pack 1
- High Availability administration (IV)
§ Most console commands have been extended with an additional option:
§ –s <serverName> executes the command on the specified server
§ –s * executes the command on the pool
§ –s *- executes the command on the pool, excluding
the local server
§ Example: tell traveler –s * status
53

54. Lotus Traveler 8.5.3 Upgrade Pack 1
- Considerations for and if using High Availability
54

55. Lotus Traveler 8.5.3 Upgrade Pack 1
- Considerations for and if using High Availability
§ Easy scaling based on your needs.
§ High Availability (as the name says ;-)) – no Traveler outage for your
users
§ Single servers could be migrated without affecting the mobile sync
of any user
55

56. Lotus Traveler 8.5.3 Upgrade Pack 1
- Considerations for and if using High Availability
§ You‘ll need additional infrastructure: the ease of just having a
Traveler server is gone.
§ Additional load balancer / reverse proxy needs to be setup – and
to be maintained.
§ Additional SQL database server cluster. Mostly you‘ll have some
of them. If not: do you have somebody who has experience in
this area?
§ Currently only IBM DB2 and Microsoft SQL 2008 supported.
56

57. Lotus Traveler 8.5.3 Upgrade Pack 1
- Considerations for and if using High Availability
§ Running HA on different data centers (maybe in different locations/
countries/continents) is not really a good idea.
§ Think about latencies...the Traveler service pool always
communicates internally.
§ And the SQL database cluster has to...yes, you‘re right, to
cluster. Think here about latencies, too.
