Adjusting Resources for a Linux Guest
� Virtual CPU consumption is high for a Linux guest
� OMEGAMON XE detects the situation
– Sends message to Operations Manager
� Action is triggered by a rule in Operations Manager
� Operations Manager issues CP commands to tune the guest
– SET QUICKDSP
– SET SHARE
� The triggered policy and action are viewable from TEP

Scheduling Image Backups of Linux Guests
� Initiated or scheduled by Operations Manager
– Schedule defined in Operations Manager to initiate
backups at specific times/intervals
• May include multiple schedules to allow quiescing/backing up one guest at a time
– Action associated with each schedule
• Linux guest is quiesced
• Request sent to Backup and Restore Manager to back up the specific DASD/minidisks requested
• Operations Manager notified when the action is complete
• Linux guest is reactivated

Performing an Image Backup of a Linux Guest
� Initiated or scheduled by the guest
– Linux guest sends message/request to Operations Manager (or any console being monitored)
– Action is triggered by a rule in Operations Manager
• Linux guest is quiesced
– Perhaps quiescing only the application running there
• Operations Manager sends request to Backup and Restore Manager
– Back up the specific DASD/minidisks requested
• Operations Manager monitors the console of the backup server
– Receives the message when backup is complete
– Triggers a rule to re-activate the guest and send a message to the Linux guest indicating completion

Detecting Disk Full Conditions of Logging IDs
� Operations Manager monitors the console of a user ID that does logging
– DIRMAINT, for example
� Disk full or early warning message triggers a rule/action in Operations Manager
– Shut down the service machine
– Send the log files to a service machine which automatically archives all files it receives
• May involve Tape Manager if archiving to tape
– Erase the log files
– Restart the service machine
