Configuring the Maximum jobs per client for NetBackup for SAP
The following procedure shows how to set theattribute.
- In the left pane of the NetBackup Administration Console, expand NetBackup Management > Host Properties.
- Select Master Server.
- In the right pane, double-click the server icon.
- In the Master Server Properties: <master server name> window, click Global Attributes.
- Change the Maximum jobs per client value to 99.
The Maximum jobs per client specifies the maximum number of concurrent backups that are allowed per client. The default is 1.
The following points help you to determine an appropriate Maximum jobs per client setting:
Determine which policies can be active concurrently based on scheduling and duration of backup.
For each policy determine the number of jobs that can be sent concurrently be the client.
For SAP with RMAN backups, how many channels are specified in the initSID.sap file or the default instance configuration?
For SAP without RMAN, this is based on the keywords in the initSID.utl file; sort_backup_type and drives.
For MaxDB, this is the count of backup medium that is used for the backup. Typically one unless a parallel medium group is used.
Check if the policy specifies a lower concurrent job limit.
Check if the settings for the storage units or storage servers that are used by the policies specify lower maximum numbers of concurrent jobs.
For tape storage units, the number of tape drives may provide a lower limit.
Check the MPX settings in the storage unit and policy; the lower MPX setting, times the number of tape drives, limits the number of jobs.
Enter a large enough value for theattribute to meet the number of jobs that SAP runs. You may need to experiment with different values at your site.
