Environment

Release : 21.2

Component : Spectrum OneClick

Resolution

The attached spectrum_1656516294308.war and admin_1656516252645.war files will address the Tomcat WebApp occasionally crashing out of memory.

To implement:

1. Download the attached spectrum_1656690884268.war and admin_1656690813907.war files and rename to spectrum.war and admin.war respectively.

2. Log into the OneClick system as the user that owns the Spectrum installation.

2. Shutdown tomcat and webtomcat as normal.

3. cd to $SPECROOT/webtomcat/webapps directory and move the existing spectrum.war and spectrum folder plus the admin.war and admin folder to another directory as backup. Ensure there are no files in the $SPECROOT/webtomcat/webapps directory.

4. Copy the spectrum.war and admin.war files to the $SPECROOT/webtomcat/webapps directory.

5. Start tomcat and webtomcat as normal. 

The spectrum.war and admin.war files will automatically be extracted in the $SPECROOT/webtomcat/webapps directory.
