8. Once the update has completed, close the terminal window by entering “exit” followed
by the enter key and log off as user “root”.
9. Start Glider Terminal, GLMPC Terminal, and Data Visualizer (from the Dock Server
web page or otherwise) on each client machine to initiate a client application upgrade.
As part of each Dock Server upgrade, a client tools upgrade (Glider Terminal, GLMPC
Terminal, and Data Visualizer) is installed on the Dock Server machine. Using Java’s
Web Start technology, these client tools are upgraded on client machines by starting the
old installed release of each tool. Each time a client tool is started, Web Start checks
the originating Dock Server machine for a tool upgrade. The machine used for the initial
install of each client tool is the originating machine. If an upgrade is found within a time
out period, Web Start upgrades the tool on the client machine and launches the
upgraded version. If no upgrade is found within the timeout period, Web Start launches
the already installed release of tool and continues to search for an upgrade. If Web
Start finds an upgrade after it has launched an old release, it caches the fact that an
upgrade exists but does
not
perform the upgrade until a subsequent launch of that client
tool.
This upgrade behavior can be confusing to users. It can result in launching an old client
tool release even though a new release is on the Dock Server machine. Thus, it is
important to check that the release displayed in the client tool’s title bar is the one you
expect. If it is not the new release, let the old release run for five or more minutes, shut
it down, and then restart it. The five minute wait should give Web Start enough time to
find an upgrade if there is one. Thus, upon restarting the client tool, a dialog similar to
figure 31 should appear to indicate that the upgrade is inprogress. Note that the
upgrade can take several minutes to complete.
2.10 Rolling back to a Previous Dock Server Release
Dock Server roll backs are available over the internet for versions 6.31 and later. Note
that rolling back Dock Server also rolls back all client tools (Glider Terminal, GLMPC
Terminal, and Data Visualizer). To rollback a Dock Server install to an earlier release,
follow these steps.
