What the VP Says...

I think you'll all agree that when the VP steps up and says something, we all tend to take his words a bit more seriously. (Seriously, I'm just a lowly tech writer myself.)

So, in case you missed it, tune into Jim Parkinson's latest blog entry to find out everything we'd like to accomplish in Comms going forward.

I think that it's very cool that he's talking about our nextgen client. With that cat out of the bag, I hope to provide some more details to get everyone excited with this new effort. The entire Comms install experience, since Jim mentioned it, is another area I'll blog about soon to clue everyone about what to expect there.

Slicing and Dicing Communications Suite 5 - The Rest of the Story

Continuing this thread on what's new in the upcoming Sun Java Communications Suite 5 release, here's the rest of the story on Instant Messaging, Delegated Administrator, Communications Express, and Connector for Outlook.

What's New in This Release of Instant Messaging

This section includes the following topics:

  • Instant Messaging XMPP Redirect Server

  • Sun Java Enterprise System Monitoring Framework Support in Instant Messaging

  • Instant Messaging Redeploy Script Changes

Instant Messaging XMPP Redirect Server

The XMPP redirect server balances the load between servers in a server pool, increasing performance by decreasing the amount of communication required between servers in a single deployment. The XMPP redirect server increases the probability that two users who will likely share presence information and messages end up on the same node. You use a redirect service to optimize resource utilization. The redirect service directs client connections to specific hosts in the server pool.

Sun Java Enterprise System Monitoring Framework Support in Instant Messaging

This release of Instant Messaging supports version 2.0 of the monitoring framework. This monitoring framework provides information on the length of time for authentication, message delivery, the number of instant messages sent through the service, and other statistics.

Instant Messaging Redeploy Script Changes

The redeploy script used to redeploy Instant Messenger resource files has been renamed to iwadmin.

Event Notification Service (ENS) Support in Instant Messaging

In this release there are two notification services for Calendar pop-ups: Sun Java System Message Queue (JMQ) and Event Notification Service (ENS). In a future release, the Communications Services products (Instant Messaging, Calendar Server, and Messaging Server) will use JMQ exclusively and ENS will be removed. However, for this release, you can continue to use ENS.

Legacy SSL and TLS Support for Instant Messaging

TLS support was added to Instant Messaging in the previous release; however, the Sun Java System Instant Messaging 7 2006Q1 Administration Guide did not adequately cover instructions for setting up TLS. TLS is used for communication between the server and clients, other servers, and Instant Messaging components such as the XMPP/HTTP Gateway. Legacy SSL is still supported for communication between clients and the multiplexor. Legacy SSL is no longer supported by the server. The Sun Java System Instant Messaging 7.2 Administration Guide now provides detailed information about setting up security for your deployment.

As a result of the implementation of TLS in Instant Messaging, you are no longer prompted to enter an SSL port for the server when you run configure.

The following iim.conf parameters are no longer used:

  • iim_server.sslport - No separate port is required for TLS connections.

  • iim_server.usesslport - No separate SSL port.

  • iim_server.secconfigdir - No longer have NSS key and certificate database for the server.

  • iim_server.keydbprefix - No longer have NSS key and certificate database for the server.

  • iim_server.certdbprefix - No longer have NSS key and certificate database for the server.

  • iim_server.coserver1.usessl - This has been replaced with iim_server.coserver1.requiressl.

The following iim.conf parameters are new for this release:

  • iim_server.requiressl

  • iim_server.sslkeystore

  • iim_server.coserver1.requiressl

Refer to the Sun Java System Instant Messaging 7.2 Administration Guide for information about using these parameters.

The Instant Messenger client uses imssl.html and imssl.jnlp only for legacy SSL connections. Instant Messenger supports TLS automatically when it connects to a server that is configured to use TLS.

What's New in This Release of Delegated Administrator

Delegated Administrator 6.4 includes the following changes and new features:

  • Support for Calendar Groups

  • Web Server 7.x Deployment

  • Access to Instant Messaging

  • Debug Log Command for the Delegated Administrator Server

Support for Calendar Groups

Delegated Administrator supports provisioning of calendar groups.

You can use Delegated Administrator to assign calendar service to a group. When the group is first invited to an event, Calendar Server creates a group calendar shared by the users who are members of the group. Invitations to the group appear on the group calendar and on the calendars of the individual members.

The following features implement support for calendar groups:

  • In the console, you can assign service packages with calendar service to groups. In the Create Group wizard, a Calendar Service Details panel allows you to specify Calendar attributes for the group. Calendar service details can be modified in the group properties page.

  • In the command-line utility, the commadmin group create and commadmin group modify commands have been enhanced to support calendar groups.

Web Server 7.x Deployment

Delegated Administrator can be deployed to Sun Java System Web Server 7.x.

When you run the configuration program, config-commda, you can configure the Delegated Administrator server and console to be deployed to Web Server 7.x.

Access to Instant Messaging

Users created in Delegated Administrator will have access to Instant Messaging (IM) service if IM is deployed on your site. Users are automatically assigned basic IM service during user creation.

You must use the Access Manager console to set and manage IM user-access levels. In this release of Delegated Administrator, the Delegated Administrator console does not provide access to IM service and does not provide an interface for managing IM user-access levels.

Debug Log Command for the Delegated Administrator Server

In the command-line utility, the commadmin debug log command creates a Delegated Administrator server log that contains debug statements generated by the Delegated Administrator servlets installed on the Web container.

With the commadmin debug logcommand, you must create the log in the /tmp/ or /var/tmp/ directory.

The commadmin debug log command supersedes the use of the url to enable logging for the Delegated Administrator server. The url used in previous releases can no longer be used for this purpose.

What's New in This Release of Communications Express

New features in Sun Java System Communications Express 6.3 include:

Support for Attachments in Events/Tasks

The Calendar component of Communications Express allows users to include attachments to an event or task.

Next Available Free Period Button

Communications Express allows users to check availability of invitees. If the invitee is not available for the day of the event, the next available free period button displays the availability of the invitee in the subsequent six days.

Address Book Sharing

The Address book component of Communications Express allows users to share their address book globally as well as to specific users. You can also assign specific permissions to users who subscribe to your address book. You can also subscribe to other shared address books.

Support for Multiple Address Book

Communications Express allows users to create and maintain more than one address books.

Preserving Customization

Starting this release, the Communications Express upgrade script will preserve all customizations that have been made in the product. This was not possible in earlier releases and all customizations were lost on a patch upgrade.

Password Encryption

Starting this release Communications Express configurator tool enctyps passwords during configuration. This is done transparently by the configuration tool. Communications Express now has a tool to encrypt and manage passwords. Administrators can change passwords by running this script.

LDAP Failover Mechanism

The LDAP failover mechanism in Communications Express balances load between a number of configured master and slave LDAP servers. This increasing performance by decreases the response time. Communications Express contains an LDAP failover Manager module that is responsible to retrieve connections from the master or slave servers. Each load balancing server maintains a pool of available free connections. Whenever a Communications Express component requires a connection to the LDAP server, the LDAP failover manager provides the component with a connection based on the load balancing strategy employed.

Mail Integration into Communications Express

Starting this release, the Webmail related user interface components have been moved to Communications Express. In the earlier releases of Communications Express, the mail related files were resident in the Messaging Server. Also, in previous releases of Communications Express, the webmail and the web container ports had to be available for it to work. As a result of this change, only the web container port needs to be available for Communications Express to work.

Removal of Access Manager SDK Dependency for Schema 2 Deployment

In previous releases, Communications Express used the following APIs and libraries to establish connections and fetch information from an LDAP store:

  • Domain MAP API (which a part of Communications Express) if Communications Express was deployed using Schema 1 mode.

  • Access Manager SDK if Communications Express was deployed using Schema 2

This made Communications Express dependent on Access Manager in Schema 2 mode even though Access Manager is not mandatory for it to work apart from just connecting and fetching information from the LDAP store. Starting this release, this dependency on Access Manager for Schema 2 has been removed. Communications Express is now shipped with a new Domain MAP API for Schema 2.

Note - As a result of this, users who log in to Communications Express cannot log on to Access Manager Console.

What's New in This Release of Connector for Microsoft Outlook

New features in Sun Java System Connector for Microsoft Outlook 7.2 include:

  • Polling multiple folders.

    A new option in the Deployment Configuration Program allows multiple mail folders, including Inbox to be checked for new unread messages. This option can be useful if message filters have been set up to automatically move incoming messages to specific folders other than Inbox, or if the direct delivery to a specific folder option has been enabled.

  • Creating and sharing multiple calendars and tasks.

  • Creating and sharing multiple address books.

  • Adding attachments to calendar events. Attachments are saved on server.

  • Viewing group memberships within contact details (applies only to the corporate directory).
