The Novell Data Synchronizer Mobility Pack creates or updates a Synchronizer system that consists of the Synchronizer services, the GroupWise Connector, and the Mobility Connector on a single server. This Synchronizer system enables you to easily synchronize GroupWise data to mobile devices.
Mobility Pack 1.2.2 provides the following enhanced features compared to Mobility Pack 1.2.1:
On-Demand LDAP Group Polling: In Synchronizer Web Admin, you can cause Synchronizer to reread LDAP groups in order to immediately bring the latest changes into Synchronizer. On the Manage Global Settings page, click .
Disk Space Monitoring Tool: The datasync-diskcheck.sh script runs automatically along with the Synchronizer services. If the /var partition where log files are stored becomes more than 90% full, the script stops the Synchronizer services to prevent data loss as a result of running out of disk space.
Event Recovery: If the Synchronizer service goes down unexpectedly, or if you stop it while it still has unprocessed events in its queue, the Synchronizer service handles previously received but unprocessed events when you restart it. This prevents the loss of unprocessed events.
Updates to the Mobility Pack are released regularly. Some updates are major version updates, such as Mobility Pack 1.1.x to Mobility Pack 1.2.x. Other updates are minor updates to an existing version, such as Mobility Pack 1.2 to Mobility Pack 1.2.x.
For a list of the bugs that have been fixed since Mobility Pack 1.2.1, see the Novell Data Synchronizer 1.2.2 Bug Fix List.

The feature preview script (previewfeature.sh) lets you enable functionality that is currently under development but not yet officially released and supported. Such functionality is disabled by default, but you can use the feature preview script to enable it.
Some task synchronization functionality that will be available in the next release is currently available for preview.
Change to the following directory:
/opt/novell/datasync
Run the following script to enable task synchronization:
./previewfeature.sh --tasks --action enable
This enables task synchronization for all users.
(Conditional) If you want to turn task synchronization off again, use the following command:
./previewfeature.sh --tasks --action disable
A Synchronizer system can communicate with only one GroupWise system. Creating multiple connectors of the same type on a single Synchronizer server is not supported. For more details, see Synchronizer System Configuration
in Mobility Pack Product Overview
in the Novell Data Synchronizer Mobility Pack Installation Guide.
The Mobility Pack is supported in a virtual environment, but performance might be somewhat slower when virtualized. Individual results might vary.
Before you run the Mobility Pack Installation program, you must create a GroupWise trusted application so that the GroupWise Connector can log in to a GroupWise Post Office Agent (POA) in order to access GroupWise mailboxes without needing personal user passwords. When you set up the GroupWise Connector as a trusted application, you need to fill in only three fields in the Create Trusted Application dialog box in ConsoleOne: , , and . Do not fill in any other fields. If you fill in additional fields, the trusted application does not work correctly with the GroupWise Connector.
When you run the Mobility Pack Installation program in YaST, you might see the following error:
The proposal contains an error that must be resolved before continuing
This error indicates that you clicked without providing the configuration information for your Synchronizer system. Instead of clicking , click , then provide the configuration as prompted. After you provide the configuration information, click .
When you run the Mobility Pack Installation program on SUSE Linux Enterprise Server (SLES) 11 SP1, the Installation program might hang if you browse to and select a file. This can occur if you try to browse to and select any of the following files during installation:
Mobility Pack ISO file
GroupWise trusted application key file
Certificate file
As a workaround, type the full path and filename for the file instead of browsing to it.
If you already have Python packages installed on the server where you are installing the Mobility Pack, the Installation program needs to update the existing packages, rather than install new packages. This does not happen by default.
When you run the Installation program, you are prompted if packages need to be updated. Enter 1 for Solution 1 to update each package.
The Mobility Pack must be installed on a server with a 64-bit/x86 processor. If you try to install it on a server with a 32-bit/x86 processor, the Mobility Pack Installation program does not detect the problem. It tries to run, but it cannot run correctly.
If the behavior of the Installation program does not match the installation instructions provided in the Novell Data Synchronizer Mobility Pack Installation Guide, make sure that you are installing the Mobility Pack on a server that meets the documented system requirements.
There are currently no plans to make the Mobility Pack available in a 32-bit version.
When you add users to your Synchronizer system, data is automatically synchronized from GroupWise to the Mobility Connector before users connect their mobile devices to your Synchronizer system. Do not add users to your Synchronizer system who do not have mobile devices. Extraneous users create unnecessary synchronization traffic in your Synchronizer system.
The standard uninstallation procedures provided in Uninstalling the Mobility Pack
in the Novell Data Synchronizer Mobility Pack Installation Guide occasionally fail to completely uninstall the Mobility Pack because of various server-specific issues. When the Mobility Pack software is not completely uninstalled, the next installation does not proceed normally. For example, you might encounter problems configuring LDAP access during installation. To ensure that the Mobility Pack software has been completely uninstalled, perform the following checks:
In YaST, click .
The Mobility Pack should not be listed. If it is still listed, select it, then click .
In YaST, click .
The Mobility Pack repository should not be listed. If it is still listed, select it, then click .
IMPORTANT:If you do not remove the existing Mobility Pack repository, you cannot successfully install the next version of the Mobility Pack software.
In YaST, click . In the drop-down list, select .
Under the heading, the Mobility Pack should not be listed. If it is still listed, select it. Review the list for any packages that were not successfully uninstalled and uninstall them.
In YaST, click . In the field, specify datasync, then click .
The list should be empty. If any Data Synchronizer packages are still listed, uninstall them.
Log in as root in a terminal window, then check for Data Synchronizer RPMs:
rpm -qa | grep datasync
If any Data Synchronizer RPMs are still installed, uninstall them:
rpm -e rpm_name.rpm
Make sure that none of the following directories still exist on your server:
/opt/novell/datasync /etc/datasync /etc/init.d/datasync* /var/lib/datasync /var/log/datasync /var/run/datasync /var/lib/pgsql
If any of these directories still exist, delete them.
After performing all these checks, reboot the Synchronizer server.
Remove the Synchronizer certificate from any workstations where you have run Synchronizer Web Admin.
For example, in Firefox, click . Select the certificate named DataSync Web Admin, then click .
Occasionally, when you shut down the Synchronizer services, one or more services fails to shut down. A message notifies you of the problem. To resolve the problem:
Use the following command to identify the processes that did not shut down:
ps -eaf | grep python
(Conditional) If the Synchronizer services are the only Python processes running on the server, use the following command to kill all of them:
killall -9 python
or
(Conditional) If non-Synchronizer Python processes are running on the server, use the following command to kill each individual Synchronizer process:
kill -9 pid
Replace pid with the process ID of each Synchronizer Python process, as listed in Step 1.
When you are finished killing Synchronizer processes, repeat the ps command to verify that all killed processes have actually shut down.
When you add or delete a large number of users or groups in Synchronizer Web Admin, the Manage Users page or the Manage Groups page might not correctly display the presence or absence of the users or groups. Refresh the page in your browser to correctly display the users or groups.
After you add a large number of users to the GroupWise Connector, the responsiveness of Synchronizer Web Admin might diminish each time you restart the GroupWise Connector. For example, it might take longer to log in to Synchronizer Web Admin, or you might not be able to navigate easily between pages while the GroupWise Connector is starting. This occurs because the GroupWise Connector verifies all of the users each time it starts. After the user verification process is completed, Synchronizer Web Admin behaves normally.
On the Connector Configuration Settings pages for the GroupWise Connector and the Mobility Connector, if you set and save general connector settings, then set and save connector-specific settings, the general connector settings are not actually saved. However, if you set and save connector-specific settings, then set and save general connector settings, all changed settings are saved as expected.
The Novell Data Synchronizer Mobility Pack is the replacement for GroupWise Mobile Server (GMS). These two synchronization solutions can coexist successfully, as long as users are transitioned from GMS to Synchronizer in a timely manner. An issue with GMS can cause a user whose mobile device is configured to use both synchronization solutions to occasionally receive a large quantity of extraneous items. As you add users to Synchronizer, you should delete them from GMS. You can continue to run GMS indefinitely to support users with older mobile devices that are not supported by Synchronizer.
In order to delete users from a connector, the connector must be running. If the connector is not running, some user event data is not properly deleted. When the connector starts again, the administrator does not need to take any additional action.
When you stop a connector in Synchronizer Web Admin and then start it again immediately, the status might indefinitely remain as . This can happen because the connector did not completely stop before you tried to restart it. The connector might have been completing a polling cycle before shutting down, even though Synchronizer Web Admin displayed the status as . When you try to start a connector that is still shutting down, it cannot start normally.
To restart the connector when this situation has occurred:
Restart the Connector Manager on the command line:
rcdatasync-connectors restart
This should change the connector status in Synchronizer Web Admin from to .
Start the connector in Synchronizer Web Admin.
Start any other connectors that stopped as a result of restarting the Connector Manager.
Some connectors restart automatically when the Connector Manager restarts.
If this problem occurs repeatedly, wait a few seconds between the time when you stop the connector and when you start it again to allow the connector to shut down completely before restarting.
Synchronizer Web Admin allows you to manually create multiple instances of the same connector. However, this configuration is not currently supported.
If you have more users than a single connector can service, you can install one or more additional instances of the Mobility Pack on additional servers until all users are being successfully serviced. Users can be organized on multiple instances of the Mobility Pack based on various schemes such as the location of the users, the location of the synchronized applications, or the desired quality of service (executives vs. regular employees, for example). Instances of the Mobility Pack do not need to mirror the structure of your GroupWise system.
