1.10.4 CTC Does Not Launch
Symptom CTC does not launch, usually an error message appears before the login window appears.
Possible Cause The Netscape browser cache might point to an invalid directory.
Recommended Action Redirect the Netscape cache to a valid directory. See the “Redirect the
Netscape Cache to a Valid Directory” procedure on page 1-122.
Redirect the Netscape Cache to a Valid Directory
Step 1 Launch Netscape.
Step 2 From the Edit menu, choose Preferences.
Step 3 In the Category column on the left side, expand the Advanced category and choose the Cache tab.
Step 4 Change your disk cache folder to point to the cache file location.
The cache file location is usually C:\ProgramFiles\Netscape\Users\yourname\cache. The yourname
segment of the file location is often the same as the user name.
1.10.5 Slow CTC Operation or Login Problems
Symptom You experience slow CTC operation or have problems logging into CTC.
Table 1-3 describes the potential cause of the symptom and the solution.
Table 1-3 Slow CTC Operation or Login Problems
Possible Problem Solution
The CTC cache file
might be corrupted or
might need to be
replaced.
Delete the CTC cache file. This operation forces the ONS 15454 SDH to
download a new set of JAR files to your computer hard drive. See the “Delete
the CTC Cache File Automatically” procedure on page 1-123 or the “Delete
the CTC Cache File Manually” procedure on page 1-123.
Insufficient heap
memory allocation.
Increase the heap size if you are using CTC to manage more than 50 nodes
concurrently. See the “Set the CTC_HEAP and
CTC_MAX_PERM_SIZE_HEAP Environment Variables for Windows”
procedure on page 1-120 or the “Set the CTC_HEAP and
CTC_MAX_PERM_SIZE_HEAP Environment Variables for Solaris”
procedure on page 1-121.
Note To avoid network performance issues, Cisco recommends managing
a maximum of 50 nodes concurrently with CTC. To manage more
than 50 nodes, Cisco recommends using Cisco Transport Manager
(CTM). Cisco does not recommend running multiple CTC sessions
when managing two or more large networks.
