During-the-Shift Tasks
•
Check files:
•
Note any bad tracks on mirrored disks and spare the bad tracks (use SCF).
•
Make sure that sufficient free space is available for dynamic extent allocation
during the day, and monitor space fragmentation. Use the LISTFREE function
of the Disk Space Analysis Program (DSAP).
•
Look for excessive file fragmentation or exceptional conditions such as extent
overlaps, unspared defective sectors, or lost free space pages. Use DSAP.
•
Check application file sizes. Make sure that online application database files are
not reaching their configured capacity. Use the File Utility Program (FUP).
•
Run PEEK on all processors to collect processor resource usage statistics.
During-the-Shift Tasks
The following tasks are usually performed during every shift:
•
Check for operator messages at regular intervals as suggested for start-of-shift tasks.
If a large number of messages is being generated, fix the problem or problems
causing the messages, or prepare to change the log files more frequently than usual.
•
Monitor processors:
•
Run PEEK on all processors. Examine the output to detect abnormal paging,
table allocation, and pool utilization.
•
Run ViewSys to monitor how busy the processors are.
•
Use the TSM EMS Event Viewer to detect excessive processor activity.
•
Monitor the spooler as suggested for start-of-shift tasks.
•
Monitor system security. Check physical security and use the Safeguard command
interpreter (SAFECOM) and TACL to:
•
Check for changes to owner IDs, file security settings, licensing, and so on
•
Monitor audit logs for unusual events
•
Check the users’ default security settings
•
Delete old user IDs
•
Monitor the network as suggested for start-of-shift tasks.
•
Monitor devices and files as suggested for start-of-shift tasks.
•
Monitor the online transaction-processing environment as suggested for start-of-shift
tasks.
•
Monitor applications.
•
Make sure that all processes that should be running are running.
•
Check room temperature and humidity.
•
Vacuum printers.
