2. Outline CDC ASM Java phoneme CDC build tutorial
Application Management System
PBP Presentation Mode (Personal Basis Profile only)

3. CDC ASM CDC AMS – Concurrently launch and manage multiple application
The Goal of CDC AMS
Robustness
Scalability
AMS system should provide quick luanching
AMS be minimized
Full native integration
Full compatibility with existing applications
Transparency

4. CDC ASM Early time uses Monolithic main()-based application
After java runtime environment to launch, run, and manage several application at once
CDC include xlet-managed application model
Thread-based concurrency and namespace-based isolation can still
interfere with each other in subtle ways
Not fully isolated
Namespace-based isolation provides security without rubustness
New Requirments
Classloader-based isolation works for well behind applications
Cannot provide robustness
Robustness needed different vendors and built for different purposes.

9. Launching CDC AMS 3 stage procedure
1st Stage: mtask server JVM instance through conventional JVM launch mechanism loading and excuting from cvm ROM emage
Mtask server JVM instance remain in memory
Wating for mtask commands
2nd Stage: cvmc driver util send an mtask command to clone itself the server jvm instance into a client JVM instance
Server JVM instance – respond to mtask command
Client JVM instance – encapsulates the AMS implementation
mtask server
JVM instance
cvm

mtask client

10. Launching CDC AMS
3rd Stage: CDC AMS can create more mtask JVM instance for encapsulating individual applications
AMS sends an mtask command to the server JVM instance clone it self.
AMS also send an mtask command to a client JVM instance to kill its process and end application’s lifecyle.

11. Launching CDC AMS Executing Shell script (Cobalt Qube)
# launch the mtask server
$CDCAMS/bin/cvm \
-Xbootclasspath/a:$AMSCLIENTJAR \
-Xserver:port=7788,initClasses=$CLASSLIST,precompileMethods=$METHODLIST \
> $SERVERLOG 2>&1 &
# wait for the mtask server to finish launching before cloning it
sleep 5
# use the cvmc driver utility to launch the CDC AMS implementation in a client JVM instance
$CDCAMS/bin/cvmc \
-host \
-port 7788 \
-command JDETACH \
-Xbootclasspath/a:$AMSMANAGERJAR:$PMODEJAR \
-Dcdcams.presentation=$PMODECLASS \
$AMSCLASS \
-server
> $MANAGERLOG 2>&1

12. Launching CDC AMS PBP Presentation Mode
Simple button base user interface
Purpose of CDC AMS is to allow multiple application to run concurrently
These application share memory and CPU resource
But, only single can be in the foreground and control GUI panel
If you want to interact with another, you must switch the foreground application
