1.10.3 Unable to Change Node View to Network View
Symptom When activating a large, multinode BLSR from Software R3.2 to Software R3.3, some of the
nodes appear grayed out. Logging into the new CTC, the user is unable to change node view to network
view on any and all nodes, from any workstation. This is accompanied by an “Exception occurred during
event dispatching: java.lang.OutOfMemoryError” in the java window.
Possible Cause The large, multinode BLSR requires more memory for the graphical user interface
(GUI) environment variables.
Recommended Action Reset the system or user CTC_HEAP environment variable to increase the
memory limits. Complete the “Reset the CTC_HEAP Environment Variable for Windows”
procedure on page 1-122 or the “Reset the CTC_HEAP Environment Variable for Solaris”
procedure on page 1-122 to enable the CTC_HEAP variable change.
Note This problem typically affects large networks where additional memory is required to manage
large numbers of nodes and circuits.
Reset the CTC_HEAP Environment Variable for Windows

Step 5 Click New under the User variables field or the System variables field.
Step 6 Enter CTC_HEAP in the Variable Name field.
