To ensure POM performance stability when POM is under high load, the following import restrictions are implemented:

• The number of imports or uploads that can run simultaneously.
• The number of records that can be imported or uploaded.

Depending on the POM system load, POM adjusts the number of imports that can run simultaneously or the number of records to import or upload. POM Home Page displays the System Restrictions widget to display the following:

• The number of simultaneous imports or uploads.
• The number of records that can be imported or uploaded.

The System Restrictions widget is displayed when the restrictions are imposed. The numbers displayed on the widget decrease during high load on the POM system and increase when the load on the POM system decreases.

Hence, this measure protects the POM system performance and stability during production. The following sections describe the restrictions:

Restriction on the number of imports or uploads that can run simultaneously applies to contact imports, contact exclusion, and DNC imports. When the limit for running simultaneous imports is reached, the new import or upload requests are placed in the queue. The restriction on the number changes dynamically based on the load on the POM system.

Even with an applied restriction, imports or uploads that are already in the running state continue to run without altering the number of imports or uploads decided at the beginning.

Restriction on the number of records that can be imported or uploaded applies to imports using file upload, file-type data source, file splitter, and to any scheduled imports using a file-type data source or splitter. The restriction on the number changes dynamically based on the load on the POM system.

When you import using a file, if the number of records exceeds the current maximum allowed number of records, the new import requests are restricted. Such new import requests are not queued and are restricted if the number of records to be imported exceeds the allowed number of records.

For restrictions on scheduled imports, the following occurs:

• If a scheduled import is non-recurring, the import is restricted and marked as complete.
• For scheduled recurring imports, if POM is under load, the import is restricted and does not start. If POM is not under load during subsequent import recurrences, the import is allowed to run normally without restriction.. If required, you can manually reschedule the import that got restricted.

Alarms are generated to notify of import restrictions. For more information about the alarms, see Troubleshooting Avaya Proactive Outreach Manager.
