With the Shared Server Model, the active server is the system running the ISEE
processes for the cluster. The ISEE$MAD process facilitates communication to the HP
Support Center or to the SPOP, in the case of the Advanced Configuration. The
ISEE$QUEUE process handles event management from Web-Based Enterprise Services
(WEBES) 4.3.1 event monitoring, maintenance activities, and incident management for
ISEE submission. The ISEE$QUEUE process also enables fail-over of the ISEE$MAD
process for planned downtime or forced process failure. The ISEE$QUEUE process will
start the ISEE$MAD process on the active server based on the configuration settings for
the cluster. All servers configured to potentially run ISEE$MAD as the active server
continuously run ISEE$QUEUE.
When selecting devices to configure as shared servers, choose devices that do not run
critical or time sensitive processes. Choose devices with a high percentage of uptime that
do not share the same downtime cycles, so that when one is down for routine
maintenance, the additional device(s) is available to run the ISEE processes.
Before proceeding with the ISEE Shared Server OpenVMS installation, read
“Understanding ISEE in Clustered Environments” on page 89.
OpenVMS Multi-server Model
The Multi-server Model requires running ISEE client processes on every node in the
cluster. This requires more system resources and time to complete installation.
Figure D-3 Multi-Server Configuration
With the Multi-server Model, all nodes are Active Servers, running the ISEE processes
independently. The ISEE$MAD process facilitates communication to the HP Support
Center or to the SPOP, in the case of the Advanced Configuration. The ISEE$QUEUE
process handles event management from Web-Based Enterprise Services (WEBES) 4.3.1
event monitoring, maintenance activities, and incident management for ISEE
submission. The ISEE$QUEUE process will start the ISEE$MAD process on the active
server based on the configuration settings for the cluster.
