The Lotus Notes Traveler 8.5.3 Upgrade Pack 1 introduces the much desired high availability (HA) feature as an option
for the Lotus Notes Traveler deployments.
It is still possible to use Lotus Notes Traveler on a single server without high availability (referred to as 'stand alone' in Upgrade Pack 1 terminology) and this is supported by the IBM, but many enterprise customers are expected to move to the HA version of the Lotus Notes Traveler.
The Lotus Notes Traveler in HA mode includes the following components:
- The IP Sprayer (a load balancer) that directs the incoming the Lotus Traveler client connection to one of the available configured servers.
- The Lotus Notes Traveler server pool that receives a connection from the load balancer.
- In HA mode, a shared relational database replaces the locally stored 'Derby' database that is used in stand alone mode. Lotus Notes Traveler 8.5.3 Upgrade Pack 1 supports using both IBM DB2 for Linux, UNIX, and Windows and Microsoft SQL Server to host the relation database. You can use the high availability features provided in both relational database servers in your Lotus Notes Traveler environment to make the end to end Lotus Notes Traveler highly available . IBM provides a free DB2 entitlement with the Louts Notes Traveler.
- All other components of mail servers, mail files, the Domino Directory are the same.
Apart from the new high availability mode, there are other new feature introduced in Lotus Notes Traveler 8.5.3 Upgrade Pack 1 including:
- Web administration
- Administration features
- Client manager
- Android enhancements
- Miscellaneous new features
Lotus Notes Traveler 8.5.3 Upgrade Pack 1 provides a new web administration tool that is based on XPages and uses the IBM oneUI framework. You can use this web interface to perform all the activities previously supported by the Lotus Notes Traveler administration application, including remote wipe, setting up security policies, and comprehensive search capabilities. The following figure shows the new administration interface which is available in both stand alone and HA mode:
The Lotus Notes Traveler server provides an administrator with different options to manage the server:
- Lotus Domino server console
- Administration application (LotusTraveler.nsf)
Lotus Domino server policies
- Lotus Domino server security settings
- Filter limits
In Lotus Notes Traveler 22.214.171.124, administrative settings could be added to NTSConfig.xml that would enforce a maximum filter window for all users. The Lotus Notes Traveler administration application now includes the ability to configure the maximum filter window settings as part of the default settings. A separate filter limit setting is provided for mail, past events, future events, and notes.
- Scheduled synchronization settings
The Lotus Notes Traveler administration application now includes the ability to configure the scheduled synchronization settings as part of the default settings which were earlier configured using the Lotus Notes Traveler clients. The SMS part of the scheduled sync settings continue to be a client only configuration option.
- Locking of individual default settings
The Lotus Notes Traveler administration application default settings configuration now includes the ability to 'Lock' individual settings. This support previously was only available by using Lotus Domino server policies. Locking a setting prevents the user from modifying that setting from their device. The following figure shows how you can lock a particular setting:
- Configuration settings consolidation
Lotus Notes Traveler configuration settings are now read from the notes.ini of the Lotus Domino server that replaces Lotus Notes Traveler specific properties and XML files used in previous versions. When upgrading an existing server, the settings is migrated.
- Trace and log Settings
Trace and log settings are now stored in the Lotus Notes Traveler database. In a high availability pool, trace settings are shared. Activating tracing on one server in the pool affects all servers.
- Server URI
The server URI for Lotus Notes Traveler has been changed from /servlet/traveler to /traveler. For backward compatibility with existing configured devices, the URI path of /servlet/traveler is still supported.
This newly released subsystem manages Lotus Notes Traveler clients that are available for download using the Lotus Notes Traveler server. An administrator can now access views in the web based administration application that display exactly which client levels are installed on the Lotus Notes Traveler server. The Client manager allows the administrator to assign specific client levels to individual users or groups of users.
Traveler high availability
The ability to run multiple Lotus Notes Traveler servers in a high availability
service pool is provided in Lotus Notes 8.3.5 Upgrade Pack 1. This feature allows devices to connect to any server in the pool at any given time. Requests are received at any Lotus Notes Traveler server and a decision is made whether to service the request locally or to route the request to another server in the pool based on which server is currently monitoring mail for the user and server loads. If a server in the pool is stopped or unavailable, device requests can be handled by the other servers in the pool without requiring a recovery synchronization.
Support for Enterprise Database Servers has been introduced to enable Lotus Notes Traveler high availability. In this release, DB2 for Linux, UNIX, and Windows and Microsoft SQL Server are supported for storing Lotus Notes Traveler Notes administration data and device synchronization data. An enterprise database is not required when running Lotus Notes Traveler on a single server (i.e. in stand alone mode).
Lotus Notes Traveler also supports the transfer of existing administration and user
synchronization data from the stand-alone Derby database to the enterprise database. This allows the migration
consolidation of existing Lotus Notes Traveler servers into a Lotus Notes Traveler HA pool.
High availability pool-aware console commands
The association of a device to a server is easy and transient. To avoid requiring an administrator to understand where a particular device or user is being processed, the management commands have been updated to communicate across servers and run the request on the appropriate server. New console commands are also added to ease the management and serviceability of the pool. .
Additional contributors to status condition
Additional factors in determining the status condition (red/yellow/green) of a server are added. The new conditions include:
- Low disk space on server
- Expiration pending of the SSL certificate used to secure Lotus Notes Traveler server to server communication
The enhancements for Android mobile devices include both client and server areas:
- Enhancements for Android Client
- Monthly view for Calendar
- Mail and Calendar UI now use larger screen size in tablets
- Enhancements for Server managed security policy
- Enforce the complex password type (OS 3.0 or higher)
- Disable local password storage
- Prohibit copy to clipboard
- Prohibit export attachments to file system
- Prohibit camera (OS 4.0 or higher)
- Application password support
- Password expiration period (OS 3.0 or higher)
- Password history count (OS 3.0 or higher)
- Prohibit unencrypted devices (OS 3.0 or higher)
Miscellaneous new features
Some general enhancements that are applicable for all mobile devices are as listed below.
Improved handling of Lotus Notes documents
Notes links that are contained in mail messages and viewed on Lotus Notes Traveler clients now include an additional URL hotspot which points to the web address of the application server. You can open the linked application using a browser on the mobile device, similar to how applications can be opened using iNotes. However, there are a number of restrictions to consider with this functionality:
- The link can only be accessed if a connection can be made from the mobile device to the user's Domino mail server and/or the Domino application server specified in the link.
- The application must be web enabled. This means that the Domino HTTP service must be running on the Domino application server and the application design must have enabled access from web clients.
Sent folder save options
Lotus Notes Traveler now synchronizes with the user preference for handling the saving of mail in the Sent Mail folder. In the previous releases, sent mail was always saved in the Sent Mail folder. Additionally, the Lotus Notes Traveler Administrator can override this behavior using the NTS_SENDMAIL_SAVE_OPTIONS notes.ini parameter. Supported values are:
- user - Honor the user's Notes and iNotes client mail save preferences (default).
- never - Lotus Notes Traveler never saves sent mail in the Sent Mail folder.
- always - Mail sent from a Lotus Notes Traveler client is always saved in the Sent folder, regardless of the user's Notes and iNotes client mail save preferences.
- noatt - Attachments in the outgoing mail will not be saved in the Sent Mail folder.
Draft mail attachment options
Lotus Notes Traveler now gives administrators the option for all users who do not to save attachments when creating a draft document on the device. When the administrator sets the notes.ini parameter NTS_DRAFT_DO_NOT_SAVE_ATTACHMENTS=true, all attachments are stripped from the document being saved on a Domino server.
