Configuring the Maximum jobs per client
The specifies the maximum number of concurrent backups that are allowed per client.
Note:
Enter a large enough value for the attribute to meet the number of jobs that SAP runs. You may need to experiment with different values at your site.
To configure the maximum jobs per client
- Open the web UI.
- On the left, select Hosts > Host properties.
- Select the primary server.
- If necessary, click Connect. Then click Edit primary server.
- Click Global attributes.
- Select the appropriate value for Maximum jobs per client.
The default is 1.
You can use the following formula to calculate a smaller value for the Maximum jobs per client setting:
The following points help you to determine an appropriate 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.
