Scheduler

Scheduler – :

Administrator-defined schedules allow for the automation of Tivoli Storage Manager server and backup-archive client operations. It basically deals with time set for taking backups.

Scheduling is of 2 Types –

1. Admin Scheduling

2. Client Scheduling

3. Admin scheduling – This type of scheduling is done to trigger the action on server.

Define Schedule schedule_name Type=Admin Description=”description” STARTDate=current_date STARTTime=current_time Duration=number Durunits=Hours Period=number PER Units=Days DAYofweek=ANY Expiration=date active=yes

1. Client Scheduling – This type of scheduling is done to trigger the action on client

Define Schedule domain_name schedule_name Type=Client description=”description” Action=Incremental STARTDate=current_date STARTTime=current_time Duration=number Durunits=Hours Period=number PERUnits=Days DAYofweek=ANY Expiration=date

Then we need to associate this node with Schedule

Define associations domain_name schedule_name node_name

There are 2 scheduling modes available to establishing communication b/w client and server -:

1. Client Pooling

2. Server Prompted

   1. Client Pooling – If client has selected client pooling mode. Client will contact TSM server at regular interval of time set in the client option file to find if there is any schedule defined for it and if so when it should run.

   2. Server Prompted – If client selects server prompted mode, the client will 1st contact server to notify the server that it is running and client is able to receive new schedule. Server respond to let client know if it has any schedule.
