1.7.5 Sluggish Cisco Transport Controller Operation or Login Problems
Symptom
You experience sluggish CTC operation or have problems logging into CTC.
Table 1-10 describes the potential cause of the symptom and the solution.
Delete the CTC Cache File Automatically
Step 1
Enter an ONS 15600 SDH IP address into the browser URL field. The initial browser window shows a
Delete CTC Cache button.
Step 2 Close all open CTC sessions and browser windows. The PC operating system will not allow you to delete
files that are in use.
Step 3
Click the Settings button on the initial browser window, then click Delete CTC Cache to clear the CTC
cache. Figure 1-19 shows the Delete CTC Cache window.
Table 1-10 Sluggish Cisco Transport Controller Operation or Login Problems
Possible Problem Solution
The CTC cache file is
corrupted. Delete the CTC cache file. This operation forces the ONS 15600 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 1-60 or the “Delete
the CTC Cache File Manually” procedure on page 1-61 .
Insufficient heap
memory allocation. Increase the heap size if you are using CTC to manage more than 50 nodes
concurrently. See the
“1.7.5.1 Set the CTC_HEAP and
CTC_MAX_PERM_SIZE_HEAP Environment Variables for Windows”
procedure on page 1-61
and the “Set the CTC_HEAP and
CTC_MAX_PERM_SIZE_HEAP Environment Variables for Solaris”
procedure on page 1-62
.
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.
