Unit 6: Central Scheduler

2 Objectives Upon the completion of this course, you will be able to: Describe the Tivoli Storage Manager scheduling modes available. Set server and client schedule options. Build a client schedule. Build an administrative schedule. Manage the event log.

3 Schedules Two types of scheduling Client scheduling – Backup/Restore and Archive/Retrieve – Client OS commands and scripts – One-time scheduled commands Administrative scheduling – Administrative commands – Scripts to automate series of events WAN/SAN Intelligent management by central scheduling TSM Server

4 Central Scheduler Mode – Client Polling Client 2 Scheduling function Schedule time 1 Query for Schedule WAIT TSM SERVER 3 Start Backup/Archive Schedules All Communications Methods Client Polling TSM DB

5 Central Schedule Mode – Server Prompted Client 1 TSM SERVER 3 Start Backup/Archive Schedules TCP/IP Protocol Only Register address 2 Schedule function TSM DB

11 Managing Client/Server Sessions Administrators with system privilege can set: Percentage of Maxsession that can be used for centralized scheduling. How many retries of a failed scheduled command. Duration between client/server retries.

14 Managing Schedules MILK DARK WHITE Admin with SYSTEM/POLICY Policy Domain: Dept. Chocolate SCHEDULE DAILY Priority 1 SCHEDULE WEEKLY Priority 3 NODES MILK DARK WHITE MKT1 MKT2 POLICY MC1 MC2 Schedule defined for specific policy domain. Multiple schedules for a policy domain. Clients associated with one or more schedules. Administrator defined and maintained. May prioritize schedules. Copy across policy domains.

16 Defining Schedules – Relative Date and Time Can specify date and time relative to the execution of the command. Useful for the scheduled commands. Relative date DATE=mm/dd/yyyy DATE=TODAY + number of days DATE=TODAY - number of days DATE=TODAY Relative time TIME=hh:mm:ss TIME=NOW + number of hours : number of minutes TIME=NOW - number of hours : number of minutes

21 Schedule Example MTWTF 24:00 01:00 Start Backup Startup window: Starttime = 01:00Function: Action = Incremental Backup Time between windows: Period = 2 daysDuration = 6 hours Action must start within startup window. Action may not complete within window. Schedule operations run serially on client. Event log maintained on server. 01:00 startup window actual backup time

22 Randomizing Example NODE ANODE B Randomize% = 50 Randomize Period 01:0004:0005:0006:0007:00 RP Startup Window Scatter schedule start time across window. Balance network/server loads. % specification Defines fraction of the window over which start times distributed. Randomization period based on time client polls. Client polling mode only. NODE BNODE A 01:30 03:01 NODE C 05:00 05:45 22:00 Polls Starts

23 Server Prompted Example TSM Server SET MAXSESSIONS SET MAXSCHEDSESSIONS SET SCHEDULE PROMPTED SCHEDMODEPROMPTED COMMMETHODTCPIP DSM.OPTDSM.SYS (UNIX) DEFINE SCHEDULE DOMAIN SCHEDULENAME ACTION=I, STARTT = DUR=6,PERIOD=1 DURU=HOURS, PERU=DAYS DAYOFWEEK=WEEKDAY Client 100 Register Schedule Start 90 23:30

24 One-time Scheduled Client Commands DEFINE CLIENTACTION command Defines a schedule Associates schedule with a client Wait parameter allows client operation to complete Schedule execution Commands executed as soon as possible by client, dependent on: – client scheduling mode – queryschedperiod for polling mode Client must have scheduler running SET CLIENTACTDURATION command Number of days before action is deleted from database.

26 Administrative Command Scheduling Administrator commands can be handled by TSM scheduler to: Automate server operations. Ensure server resources are available to clients. Ensure server functions performed with minimal manual intervention. Type of schedule (TYPE=Administrative). Can view administrative command schedule event status. Output sent to the activity log. Not associated to a policy domain. Administrator Schedule Commands TSM SERVER

27 Administrator Scheduling Commands Lower threshold to immediately start migration. Lower threshold to immediately start reclamation. TSM server database backup. Inventory expiration. Storage pool backup. EXAMPLES All administrative commands except QUERY ACTLOG TSM SERVER

28 Instructor Demonstration

29 Managing Database Events Each scheduled operation is an event. All events are recorded in the database. Provides an audit trail of completed or missed events Event records purged based on retention period Event Log Schedules DATABASE SET EVENTRETENTION 10

30 Query Event Command Display information on scheduled and completed events. All administrators can query events. Two types of query All events (general reporting) Failed events (exception reporting) Can select subset of a report by Policy domain, schedule name, node name, date Two report formulas Standard or detailed
