Performance

On the Performance tab, the control of the current document, that is, for example, load balancing, preloading, concurrent session access, and audit logging, can be managed.

Sessions

Maximum Number of Concurrent Sessions

To choose a maximum number of concurrent sessions towards the current document, enter the desired number in this text box. An empty field means no limit.

Maximum Inactive Session Time

User sessions, which have had no activity during a specified time limit, can be configured to be closed by the QVS. To set the session timeout, enter a suitable figure in this text box.

Note: The maximum inactive session time can also be set on a global level. The session time with the lowest value takes precedence. If the session time entered in this text box is lower than the global session time, the global session time is disregarded.

Performance

If left empty or set to 0 means no limit.

Document Timeout

Open documents take up valuable system resources (that is, memory space, RAM, is allocated) and should not be allowed to remain open when not in use. However, if a document is closed too quickly, the users may get longer delay times when accessing the document, because the server has to reopen it. This value controls for how long a document will be allowed to be unused before the QlikView Server (QVS) closes the document and reclaims the resources.

Enable Audit Logging

To enable the audit log functionality, tick this check box. To disable the audit log functionality, untick this check box.

Logging

Document Control

Note: The features under the Document Control heading are only available when distribution has been configured for the document.

Server

Select a server in the drop-down list.

Document Available

To configure the load balancing, that is, on which nodes the current document is to be available, select one of the following options:

  • Always on All Nodes, meaning availability on all nodes.
    • Preload
    • To make the current document quickly accessed at all times, by preloading it into the primary memory of the server, tick this check box. To disable the preload function, untick this check box.

      Note: Using the preload functionality will use memory resources also when no user is accessing the document.
  • Customize, meaning that the availability can be customized.
  • Customize

Customize

If the Customize option was selected in the Document Available field, customize the following:

Cluster Node

Presents an auto populated list of all of the servers and clusters, including all cluster nodes, that are selected for distribution.

Document Available

To configure when the current document is to be available, select one of the following drop-down list options:

  • Never, meaning that the current document will never be loaded on the node.
  • Always, meaning that the document will always be available to be loaded on the node.

Preload

To make the current document quickly accessed at all times, by preloading it into the primary memory of the server, tick this check box. To disable the preload function, untick this check box.

Note: Using the preload functionality will use memory resources also when no user is accessing the document.
Note: This option is only available if the Always option in the Document Available field was selected.
