Nortel Networks AS 5300 manual Batch processing, Resource use, Bulk provisioning of users

26Using the Bulk Provisioning Tool

In most cases, variables and properties used by the BPT provisioning methods map to fields in the Provisioning Client. For Provisioning Client field descriptions, see AS 5300 Provisioning Client Help, NN42040-502.

For example, the addRole provisioning method maps to the Add a New Role window of the Provisioning Client (Admins > Add Roles).

Batch processing

A maximum of 1000 entries are processed together at a time. All bulk processing is on an all-or-none basis.

For example, you can do a bulk add of 3000 subscribers to the system from a file. Each subscriber is one line in the file. The BPT processes the information in three blocks of 1000 lines each. If an error occurs during processing of a block, such as a user name already in use, the BPT will not process any lines in that block.

Resource use

The BPT processes the provisioning information before uploading it to the database. During the processing, the BPT uses all available CPU resources, whether the processing is performed on a server or a workstation. CPU usage declines as the provisioning data is uploaded to the database.

When performing bulk provisioning using files with a large number of entries, use a BPT residing on a workstation. Performing the task on a server can affect the performance of in-progress sessions using the component services running on the server.

Nortel recommends using the BPT during off-peak times or maintenance windows when large amounts of information are being added.

Bulk provisioning of users

Bulk provisioning of users (through BPT or an OPI client) puts a large load on the database in the AS 5300 system. Therefore, bulk provisioning must be throttled to prevent the database from becoming overloaded while handling the BPT "add user" requests. The BPT or OPI client must implement the following required sleep/wait times between "add user" requests when adding users in bulk:

•For a system running at 80 percent call capacity, add 500 users at a time. Sleep/wait at least 300 seconds before adding the next 500 users. This rate is approximately 6000 users added an hour.

•For a system running at 20 percent call capacity, add 500 users at a time. Sleep/wait at least 225 seconds before adding the next 500 users. This rate is approximately 8000 users added an hour.
