Archiving the LMS log files

LMS log files should be archived on regular basis. Otherwise, the files could continue to grow until no space is left on the hard drive.

Setting the size and frequency of the Delivery Server progress record update (for LMS systems using Oracle backend only)

Specific LMS and Oracle parameters and settings are used to determine the number of progress records that are sent from the delivery server to the Learning Server at each update. These parameters can be changed to tune LMS performance.

MaxRecords and Minutes parameters (LMS parameters)

Use the following procedures to change these parameters to tune LMS performance.

1.Go to the ds-settings.xmlfile located in the DS WEB-INF\classesdirectory.

2.Open this file for editing.

3.The first parameter that can be changed is maxRecords. The example shows how this parameter is represented in the ds-settings.xmlfile.

<!--================================================================

SendProgressTask

=============================================================== -->

<sendprogresstask component="com.ibm.workplace.elearn.module.SendProgressTask"

maxRecords="500"/>

The default maxRecords value should be set to 500 to limit the number of records handled at each update.

4.The second parameter that can be changed is minutes. The example shows how this parameter is presented in the ds-settings.xml file.

<!-- ==== task to send student progress data to the LMM ==== -->

<task name = "module.SendProgressTask.1" ownerId = "module.SendProgressTask" taskId = "1"

minutes = "5" />

The number of minutes should be changed to 2.
