Issue/Introduction:

The OneClick client is slow and may show the following symptoms:

Frequent disconnect/reconnects (red border)

Topology views hang when initializing

List views take a long time to populate

Searches take a long time to produce results.

When reviewing the OneClick Tomcat log, the "waitForReadTasks timed out" message is seen:

Apr 04, 2017 07:06:27.020 (http-bio-443-exec-2) (MODELREPO) - waitForReadTasks timed out

Cause:

The problem is due to a bottleneck with the amount of information being processed in the model repository.

Environment:

Release: SDBSFO99000-10.2-Spectrum-Device Based Suite-Server FOC
Component:

Resolution:

Cange the ModelRepository reads from 500 to 5000 in the <SPECROOT>/tomcat/webapps/spectrum/WEB-INF/web.xml:

Change this:

(context-param xmlns="")

(param-name)com.aprisma.topo.ModelRepository.ThrottledModelReadCount(/param-name)

(param-value)500(/param-value)

(description)

This parameter defines the maximum number of models the Model Repository will read in a single request to a SpectroSERVER.

(/description)

(/context-param)

To this:

(context-param xmlns="")

(param-name)com.aprisma.topo.ModelRepository.ThrottledModelReadCount(/param-name)

(param-value)5000(/param-value)

(description)

This parameter defines the maximum number of models the Model Repository will read in a single request to a SpectroSERVER.

(/description)

(/context-param)

Stop and restart tomcat for the change to take effect.

Additional Information:

The com.aprisma.topo.ModelRepository.ThrottledModelReadCount parameter in the web.xml has been increased to 5000 by default in Spectrum 10.03.00.

If you are still seeing this error, increase the value to 7500 and cycle tomcat
