Disabling automatic processes and setting schedules

Edit online

Disable automatic processes like inventory expiration, migration, reclamation, and identification of duplicate data and set up schedules so that you can control when these operations are completed during the daily schedule.

About this task

Review the following sections for examples of disabling automatic operations and setting up schedules. Some general setup steps are omitted and the example uses a particular order for the server processes. However, you can reorder the processes to better fit your environment.

Procedure

Disable automatic inventory expiration by setting the EXPINTERVAL server option to zero.
```
setopt expinterval 0
```
Disable automatic migration and reclamation processes by using the DEFINE STGPOOL command to set the HIGHMIG and RECLAIM parameters to a value of 100.
You might have to increase the number of allowed processes for migration and reclamation in order for them to complete in a reasonable amount of time. The actual number of processes depends on available tape drives. If you have already defined storage pools, you can change values for the MIGPROCESS and RECLAIMPROCESS parameters by using the UPDATE STGPOOL command.
```
def devc LARGEFILE devt=file mountlimit=500 maxcap=20480m dir=/tsmfile
def stg FILEPOOL LARGEFILE maxscratch=200 reclaim=100 hi=100 lo=0 migpr=4 
reclaimpr=20 next=tapepool
```
If you have storage pools that are defined with data deduplication enabled, disable the duplicate identification processes:
```
def stg FILEPOOL LARGEFILE maxscratch=200 reclaim=100 hi=100 lo=0  dedup=yes 
identifypr=0 migpr=4 reclaimpr=4
```

What to do next

Example: Setting a schedule for the client backup window

This example initiates an incremental backup of all associated nodes in the STANDARD domains.

The schedule starts daily at 8:00 PM by using server-prompted scheduling mode. The long-running schedules continue past the duration, so a shorter duration can be used to force those schedules to start close to the beginning of the start window.

def schedule standard nightly_backups description="Nightly backups of nodes in 
domain standard" starttime=20:00 duration=5 durunits=hours period=1 perunits=days

Example: Setting up the server maintenance schedule

Schedule server maintenance operations to run outside of the client backup window, with as little overlap as possible.

You can control the timing of schedules for maintenance tasks by setting the start time in combination with the duration time for each operation. Here is an example of how you might time each process:

08:00 - end: Storage pool backup.

11:00 to 13:00: Identification of duplicates.

13:00 - 15:00: Inventory expiration.

14:00 - 16:00: Storage pool migration.

16:00 - 18:00: Reclamation processing.

18:00 - end: Database backup, including volume history and device configuration backup.

20:00 - end: Client backup.

After you determine a timeline, use the DEFINE SCHEDULE command to create schedules for each process. You can include scripts in each schedule so that commands are processed automatically. Use the DEFINE SCRIPT command to create a script and the UPDATE SCRIPT command to add lines.

The following scripts are examples of how to define each server task:
