The ECS Maintenance system task removes outdated ECS data, provided that the state is Reprocessed.

The number of days to keep data is set in the ECS Maintenance configuration dialog (see ECS Maintenance System Task Configuration). It is also possible to fully turn off the cleanup of UDRs, Batches, Statistics, or all of them. The Statistics can be reported by email. This is configured in the Report tab of the task.

When the ECS Maintenance System Task is executed, a number of things happen:


  • UDRs, batches, and ECS statistics are removed from the ECS according to the settings in the Cleanup tab. See Cleanup Tab in ECS Maintenance System Task Configuration for further information.

    Info!

    This information is only for customers using versions of that are older than 8.1.8.0!

    When using PostgreSQL as your Platform database, if you have a large number of UDRs or batches in ECS, the removal of the UDRs and batches will be slow and can sometimes be frozen. To speed up the process, you can remove the foreign key reference from the following tables:

    UDR or BatchTablesForeign Key Reference
    UDR

    mzowner.ecs_mim

    mzowner.ecs_udr

    mzowner.ecs_udr_error

    ecs_mim_txn_id_fkey

    ecs_udr_txn_id_fkey

    ecs_udr_error_ecs_udr_id_fkey

    Batch

    mzowner.ecs_mim

    mzowner.ecs_batch

    mzowner.ecs_batch_error

    ecs_mim_txn_id_fkey

    ecs_batch_txn_id_fkey

    ecs_batch_error_txn_id_fkey

    You can use the alter SQL command to drop the foreign key reference:

    alter table mzowner.ecs_mim drop constraint ecs_mim_txn_id_fkey;
alter table mzowner.ecs_udr drop constraint ecs_udr_txn_id_fkey;
alter table mzowner.ecs_batch drop constraint ecs_batch_txn_id_fkey;
alter table mzowner.ecs_batch_error drop constraint ecs_batch_error_txn_id_fkey;
alter table mzowner.ecs_udr_error drop constraint ecs_udr_error_ecs_udr_id_fkey;

    If the number of days after which data should be removed has been configured to 0 (zero) days, data is removed every time the ECS_Maintenance System Task is executed, with a minimum time interval of one hour.

  • An ECS Statistics Event is generated containing information about the number of UDRs associated with every error code. This occurs at time intervals configured in the ECS_Maintenance system task, see ECS Maintenance System Task Configuration.

    See 4.3.22 ECS Statistics Event for further information about how to configure notifications for the ECS Statistics Event.

  • Statistical information is sent to the ECS Statistics, according to what is configured in the ECS_Maintenance system task. See the Report Tab in ECS Maintenance System Task Configuration.

  • An email containing statistical information is sent to the email recipient specified in the ECS_Maintenance system task. See the Report Tab in ECS Maintenance System Task Configuration.

    For further information on how to configure mailserver and port, see 2.6.4 Platform Properties in the System Adminstrator's Guide.


Note!

The ECS is designed to store a fairly limited amount of erroneous UDRs and batches. It is therefore important that the data is extracted, reprocessed, or deleted from the ECS on a regular basis.
