Raise User Limits
If User Limits are low on the Application Servers and possibly Mediation Servers, these can impact
threading and normal server behaviors.
Web Server
The memory configuration (heap min/max) should also be the same for all server environments.
Portal Memory Settings
To manually change the web portal heap settings, change the setenv.sh (Linux) or
setenv.bat (Windows) file:
set "PORTAL_PERMGEN=512m"
set "PORTAL_MAX_MEM=3072m"
set "PORTAL_INIT_MEM=768m"
set "PORTAL_32BIT_MAX_MEM=768m"
These files are in the Tomcat***/bin directory. For Linux, restart the portal service to apply new
memory settings. In Windows, besides updating
setenv.bat you must run service.bat
update
in that same directory.
You can increase these to even higher figures if your system has the memory available.
NOTE:
Make sure only one Tomcat process is running, otherwise your web server may exhibit poor
performance.
Post Upgrade Web Portal Problems
After applying patches, restarting processes or other recent activity, web portal exhibits undesired
behavior like the following:
• Displaying pink bar in application portlets indicating applications are
temporarily
unavailable
.
• Message in application portlets indicating
resource unavailable .
• Actions screen does not appear after right-click device and choosing
Actions .
• Inability to expand hierarchies or a previously selected hierarchy expands when clicking
another hierarchy.
Solution: These, and other symptoms, can stem from browser caching or attempting to login too
soon after starting the application. To resolve, try waiting and/or clearing the browser cache.
Clustering
You must enable Clustering on multiple web servers, otherwise index and users become out of sync.
To solve this: enable clustering on the web servers by turning on cluster properties found within
synergy/conf/server-overrides.properties
