Customers

Within the multi-subsidiary version, tests for each section are performed separately for each company.

  1. Customers have been correctly grouped:

a. Suspended customers and those with the Suspended status retain the corresponding status after the migration.

Test Environment

For RADIUS (DHCP) workflow:

  1. hard is set up as a cluster.

  2. Test authentication and authorization is successfully performed (attention: should be checked on the production network with real customers!).

  3. All IP addresses for access servers have been entered in the network service settings and in the FreeRADIUS configuration file.

  4. New IP addresses are assigned from the source pool.

  5. Real / fixed IP addresses are assigned by Hydra.

  6. Services are switched on/off on BRAS via event execution.

  7. Accounting packets are being received, traffic is accounted, there is no unaccounted traffic at the test database.

  8. Watchdog is set up for all FreeRADIUS instances. 

For Netflow accounting scheme:

  1. Netflow data is forwarded to the collector server (hcd).

  2. There are traffic class specifications entered in the system, and the traffic data is accounted accordingly;

  3. Within the registry for IP addresses, all IP addresses used for dynamic assigning are entered.

  4. All equipment for which traffic should be accounted is entered into the system (including provider equipment).

Telephony

  1. CDRs are rated properly (as per rating over the previous periods and reconciliation/checking).

  2. Files from PBX are automatically stored in the assigned directory at the server.

  3. CDR importing script runs periodically and performs the import.

Data Migration

  1. All automatic checks performed in the Migration application are successful.
  2. Latest migration has been verified by the Customer.
  3. Latest migration has been verified by Latera employee.
  4. Latest successful migration has been performed in less than two days; no changes have been made to the unload algorithm and the migration data during this period.

External systems

  1. Invoice export to ERP software is successfully performed by the Customer for the test customers. Importing script executes without faults.

Backup

  1. Production database dump is automatically collected daily and copied to a safe storage.

  2. The latest production database version with the pre-migration state is backed up and stored at the Latera server.

  3. Auxiliary server backup and production database dump to the Latera server is turned off.

  4. Replication is set up and is properly performed (should be checked at the backup server).

Payments acceptance

  1. Payments acceptance via payment gateways has been successfully tested for faults.

  2. Production certificates and credentials are used in hpd's configuration.

Business processes

  1. New customer connection process has been tested.

  2. The plan of actions for all frequently arising customer support issues has been clarified (viewing PPP sessions, password changing, etc.).

Administration

  1. Hardware server configurations correspond to Commercial Proposal requirements (CPU, RAM, storage). It applies both to the Customer owned servers and SaaS installations.

  2. All Hydra's scheduled tasks required for system operation run without faults or warnings.

    1. For all scheduled tasks operating with CDRs and the RADIUS server correct parameters are set up (Forced closing old CDRs, Deleting old CDRs, Processing session RADIUS accounting data).

3. Debug logging is disabled for all modules and agents.

4. The system servers have the latest stable versions of the following installed:

    1. Core (database)

    2. Web apps

    3. Agents.

5. All Debian Linux security updates are installed.

o install updates, it is necessary to perform the following command:

root@billing:~# aptitude update && aptitude upgrade

Note: When performing updates, it is obligatory to review the list of updates in detail. There should be no unexpected updates of Hydra modules.

6. Server monitoring has been set up for:

    1. free disk space  

    2. RAM

    3. CPU utilization

    4. other important metrics

9. Default passwords to all services have been changed, including those

  1. for Oracle users:
    • AIS_NET
    • SYS
    • AIS_ISP_OFFICE
    • AIS_USER_OFFICE
    • AIS_RPC
    • others (if necessary)
SET LINESIZE 1000;
SET PAGESIZE 1000;
SELECT USERNAME,
       VC_PASSWORD,
       'ALTER USER ' || USERNAME || ' IDENTIFIED BY "' || VC_PASSWORD || '";' AS VC_COMMAND
FROM   (
  SELECT USERNAME,
         SUBSTR(
           TRANSLATE(
             DBMS_RANDOM.STRING('p', 250),
             'A `~!@#$%^&*()-=_+[]\{}|;'':",./<>?',
             'A'),
           1, 24)        AS VC_PASSWORD,
         ACCOUNT_STATUS
  FROM   DBA_USERS
  WHERE  ACCOUNT_STATUS    = 'OPEN'
  OR     USERNAME       LIKE 'AIS\_%' ESCAPE '\')
ORDER BY USERNAME;


10. Servers within Hydra are completely ready for going live (should be checked for each server separately):

    1. Configuration corresponds with the one in the commercial proposal.

    2. All necessary services are working after the system restart (should be checked via reboot!)

    3. IP address and server hostname are assigned

    4. Firewall is set up and turned on:

      • No Hydra services are unnecessarily exposed

      • Access to Service Provider Console is allowed only from internal Customer subnets and Latera servers

      • There is no access to 21902 and 21903 TCP ports which were previously opened during implementation stage for connections from IP address 144.76.78.80.

e. Valid timezone is set up, NTP time synchronization is enabled. 

11. Customer Technical Datasheet is created and stored in Latera database.

12. An up-to-date Oracle DST version is used.

13. The number of customers is the same as per the License (active_users1 – total amount of customers in Active state, active_users2 – total amount of customers in Active state having at least one unclosed subscription, active_users3 – total amount of customers having at least one payment or charge in last 6 months)
