Step 7
Launch Internet Explorer and open another CTC session. You should now be able to access the CTC
Help.
1.9.2 Unable to Change Node View to Network View
Symptom
Logging into CTC session, 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.
Table 1-7 describes the potential cause of the symptom and the solution.
Set the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP Environment Variables for Windows
Note
Before proceeding with the following steps, ensure that your system has a minimum of 1 GB of RAM.
If your system does not have a minimum of 1 GB of RAM, contact the Cisco Technical Assistance Center
(TAC).
Step 1 Close all open CTC sessions and browser windows.
Step 2
From the Windows Start menu, choose Control Panel > System .
Step 3 In the System Properties window, click the Advanced tab.

Table 1-7 Unable to Change Node View to Network View
Possible Problem Solution
The browser stalls when
downloading files from
a port because the
display requires more
memory for the
graphical user interface
(GUI) environment
variables. Reset the system or user CTC_HEAP environment variable to increase the
memory limits.
See the “Set the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP
Environment Variables for Windows” procedure on page 1-51 or the “Set
the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP Environment
Variables for Solaris” procedure on page 1-52
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.
