Portal client parameter tuning
This section provides some information about parameters you might consider editing to improve portal client performance and usability.
The parameters are set in the following files according to operating system:
- ITM_HOME\CNP\cnp.bat (or cnp_instance_name.bat)
For example: C:\IBM\ITM\CNP\cnp.bat
- ITM_HOME/OS_Specific_Directory/cj/bin/cnp.sh (or cnp_instance_name.sh)
For example: /opt/IBM/ITM/li6243/cj/bin/cnp.sh
Be aware that on each occasion maintenance or reconfiguration takes place in your environment these files might be recreated and changes lost and need to be reapplied.
- cnp.databus.pageSize
- Number of rows to fetch in single logical page for any workspace table. By default 100 rows are returned. Although there is no limit to what you can set here, the larger the page size, the more memory required at the client and portal server. To increase manageability you might want to edit this value to return more rows.
- cnp.attachment.total.maxsize
- Use this parameter to control the maximum size of all the files attached to an acknowledgment. Consider editing this parameter if the size of event attachments are too large and are causing network issues, or alternatively you have excess capacity that might be used and attachments have been discarded. Enter the maximum size in bytes, such as 1000000 for 1 MB. The default value is 10 MB.
- cnp.attachment.segment.maxsize
- This parameter enables you to set a size limitation for individual files attached to an acknowledgment. Enter the maximum size in bytes, such as 250000 for 250 KB. The default value is 1 MB.
The following two parameters control the behavior when expanding items in the Navigator view which have a large number of items in the expanded list. The amount of time required to expand Navigator branches depends on how many items are in the expanded list. These parameters allow you to control how many items are expanded at a time.
- cnp.navigator.branch.pagesize
- The number of items to fetch on a Navigator branch expansion request. The default value is 25.
- cnp.navigator.branch.threshold
- The warning threshold for Navigator branch expansion requests. The default value is 100.
The following four parameters control the behavior of the Situation Event Console view when it is initially displayed on a workspace, and when it adds events to the display. The default values allow the portal client user to make selections while events are processed in the background.
- cnp.siteventcon.initial_batchsize
- Maximum number of events that the situation event console will process in the first event batch cycle. The default value is 100.
- cnp.siteventcon.initial_dispatchrate
- Number of milliseconds that will elapse after the first event batch cycle is processed by the situation event console. The default value is 5000 milliseconds (5 seconds).
- cnp.siteventcon.batchsize
- Maximum number of events that the situation event console will process in all subsequent event batch cycles. The default value is 100.
- cnp.siteventcon.dispatchrate
- Number of milliseconds that will elapse after each subsequent event batch cycle is processed by the situation event console. The default value is 1000 milliseconds (1 second).
Settings made here at the client level take precedence over those at the monitoring environment level. If you have specified a setting at the client level, then any event variables defined within the portal server configuration are ignored. If you have not specified a setting at the client level, the portal server variables are used. If you have not specified any settings, the default values are used.
