NetVault 13.0 - Administration Guide

The Schedule Manager (nvsched) runs on the NetVault Server. This process manages the job schedules and queues. It also manages the Scheduler Database.

The Schedule Manager initiates the Job Manager to start a job instance, and schedules the next instance for recurring jobs; the Job Manager runs the job. This process also updates the Job Status page and provides job scheduling data to the Reporting utility.

You can modify the Schedule Manager settings from the Change Settings page.

Configuring default settings for Schedule Manager

To configure default settings for Schedule Manager:

In the Navigation pane, click Change Settings.

On the NetVault Server Settings page, under Services, click Schedule Manager. In the Schedule Manager dialog box, configure the following settings.

Table 132. Schedule Manager settings
Setting	Description
Number of days to keep job status	This setting determines display period for job status records. The default setting is seven days. To change the display period, type or select a new value. The display period is specified in number of days. NOTE: This setting just hides the display of job status records on the NetVault WebUI. It does not delete the records from the Scheduler Database.
Number of days to keep report job histories in the database	This setting determines the retention period for report job history. The default setting is 90 days. To change the retention period, type or select a new value. The retention period is specified in number of days. After the retention period expires, these records are removed from the Scheduler Database.
Number of days to keep other job histories in the database	This setting determines the retention period for backup and restore job history. The default setting is 90 days. To change the retention period, type or select a new value. The retention period is specified in number of days. After the retention period expires, these records are removed from the Scheduler Database.
Number of days to keep non-scheduled jobs in the database	This setting determines the retention period for non-repeating jobs. The default value for this setting is 0 (zero). With the default setting, the job definitions of non-repeating jobs are retained indefinitely. To delete these jobs after a specified period, type or select a new value. The retention period is specified in number of days. NOTE: Because the jobs using the Triggered schedule type have no physical scheduled time, they are also deleted after the specified period elapses. If you are using Triggered jobs in your NetVault environment, do not use this setting. NOTE: This setting is also applied to report jobs that use any non-repeating schedule type. Therefore, we recommend that you do not change the default value for this setting. If the default value is changed, canned reports that have run once using any non-repeating schedule are removed from the View Reports page after the specified interval.
Maximum simultaneously active jobs	This setting determines the maximum number of simultaneous jobs that you can run in NetVault. By default, the Schedule Manager supports a maximum of 200 simultaneous jobs, including backup, restore and report jobs. To change the setting, type or select a new value. NOTE: Each active job requires some amount of shared memory. An increase in the number of active jobs might have an impact on the overall performance of NetVault.
Exclude reports jobs from jobs management views	To display report jobs on the Job Status page, clear this check box. These jobs are excluded by default.
Exclude reports jobs from policy management views	To display report jobs on the Manage Policy page, clear this check box. These jobs are excluded by default.
Exclude restore jobs from policy management views	To display restore jobs on the Manage Policy page, clear this check box. These jobs are excluded by default.

Click Apply to apply the new settings and close the dialog box.

Configuring default job priority settings

The Schedule Manager assigns a default priority level to each job type (backup, restore, and report). These default settings are applied globally to all backup, restore, and report jobs. The priority settings are used to prioritize resource allocation when two or more jobs are scheduled to run at the same time. You can change the default job priority settings from the Change Settings page.

By default, the Schedule Manager assigns the following priority levels:

•

Backup job: 30

•

Restore job: 20

•

Report job: 50

To change the priority settings globally for all jobs, use the following procedure. You can override the priority setting for an individual job by configuring the Job Priority option in the Schedule Set. For more information, see Creating Schedule Sets, Table 35.

To configure default job priority settings:

In the Navigation pane, click Change Settings.

On the NetVault Server Settings page, under Services, click Schedule Manager. In the Schedule Manager dialog box, configure the following settings:

•

Default backup job priority

•

Default restore job priority

•

Default report job priority

Type or select a value from 1 through 100. 1 denotes highest priority, while 100 denotes lowest priority. A job with a priority level of zero (0) runs as a background task.


	NOTE: If you configured a Secondary Copy, the Secondary Copy job has two requests: one for read and another for write. When you set a priority to the Secondary Copy job, the first request (source request) receives the priority that the user assigns to it; the subsequent request (destination request) served as first priority in the background with priority 0 or 1. This implementation is to avoid waiting for the destination media request to be served if the source media is available.
