Description:

This article describes how to enable the automatic execution of the suite database maintenance, to preserve the DB efficiency.

The maintenance will execute every day at a configurable time. Since the execution could slow down some operations, it is recommended to schedule the execution in the off-peak hours (normally at nigh time).

How-to:

1) Edit the file StonevoiceAS\Apps\FW\Settings\FW.Watchdog.Service.config.xml and add the following parameters (set the preferred execution time in the 24h format):

<preference key="dbmaintenance.execution.enabled" value="true" />
​<!-- Scheduled time of database maintenance operations (HH:mm, i.e. 24H format) --> 
​<preference key="dbmaintenance.execution.time" value="03:30" />

2) Save the file.

3) From the Windows Services panel restart the service "Imagicle Monitoring", to apply the change.

Notes 

  • The duration of the maintenance operation depends on several factors: amount of stored data, SQL Server performances, date of the last maintenance execution. It can range from a few seconds to some hours for biggest databases. A UCS Suite running a lcoal SQL Express instance usually takes less than 10 minutes. 
  • In case of high availability configurations with mutiple Imagicle nodes:
    • if the database model is shared (all nodes pointing to the same DB), you must enable the DB maintenance on one Imagicle server only (tipically the first one);
    • if the database model is replicated, you must schedule the maintenance on all Imagicle servers. The recommendation is to differentiate the execution time of at least 1-2 hours across the different nodes, because the simultaneous execution may raise temporary issues (and alerts) in the DB replication mechanism.
