Advanced

On the Advanced tab, the QlikView Distribution Service (QDS) handling of the QlikView engine (QVB.exe) can be managed.

QlikView Engine

Max Number of Simultaneous QlikView Engines for Distribution

To set the number of QVBs that the QDS can send tasks to simultaneously, enter the desired number in this text box.

When the QDS detects that a task is to run (either manually or triggered), the QDS adds the task at the end of a queue that is based on the “first come, first served” principle. The QDS then goes through the queue and starts up the needed number of QVBs. If there are more tasks in the queue than QVB engines allowed by this setting, the QDS waits until a currently running QVB finishes and then starts up a new QVB to handle the outstanding tasks in the queue.

Note: When distributing a PDF file, QlikView uses two concurrent QVB engines to increase the distribution performance. This means that the maximum number of simultaneous QVB engines may be exceeded, which, in turn, means that the number of concurrent PDF distribution tasks should be kept to a minimum.
Qmcwh_note: For example, if the maximum number of simultaneous QVB engines for distribution is set to four and four distribution tasks are initiated, four QVB engines are started (that is, one for each task). To increase the distribution performance, an additional QVB engine is started for each task, possibly taking the total number of simultaneous QVB engines to eight, which may have a negative impact on the performance of the QlikView system.

Default value: 4.

Max Number of Simultaneous QlikView Engines for Administration

To set the number of simultaneous QVBs that the QDS can use for the management of tasks in the QMC, enter the desired number in this text box.

Default value: 20.

Section Access

When section access is defined in the documents, it may be necessary to configure a specific entry for the QDS to avoid that it interfere with the work of the task. By default, the QDS will apply the section access associated to the Windows user under which the service run. This may be overridden at each task. If a default override is preferable, it can be defined by configuring the login credentials in the following text boxes:

User Name

To configure the user name, enter the desired credentials in this text box.

Password

To configure the password, enter the desired credentials in this text box.

Work Order

To send a work order to the designated QDS, click on the Send Work Order button.
