Java Plug-in If you have a Web Tools session open and you open a second session using the
File > New browser menu, this results in unexpected behavior of the original
Web Tools session. For example, you cannot change Admin Domains in the
second session.
Web Tools supports only one browser instance per JRE, and when you open
another window using the File > New menu, the two windows share the same
JRE environment.
Workaround: Open two independent browser sessions.
Loss of Connection Occasionally, you might see the following message when you try to retrieve
data from the switch or send a request to the switch:
Switch Status Checking
The switch is not currently accessible.
The dialog title may vary, because it indicates which module is having the
problem.
This is caused by the loss of HTTP connection with the switch, due to a
variety of possible problems. Web Tools will automatically try to regain the
connection. While Web Tools is trying to regain the connection, check if your
Ethernet connection is still functioning. If the problem is not with the Ethernet
connection, wait for Web Tools to recover the connection and display the
following message:
You will have to resubmit your request after closing this
message.
If the temporary switch connection loss is caused by switch hot code load, or
other similar operation, the Switch Explorer you are currently running can be
downloaded from a different firmware version than the new one. In this case
the following message displays:
Switch connection is restored. The firmware version you are
running is not in sync with the version currently on switch.
Close your browser and re-launch Webtools.
You need to close Switch Explorer and relaunch Web Tools to reopen the
connection.
Out of Memory
Errors
If you are managing fabrics with more than 10 switches or more than 1000
ports, or if you are using the iSCSI Gateway module extensively, you might
encounter out-of-memory errors such as the following:
java.lang.OutOfMemoryError: Java heap space
To avoid this problem, increase the default heap size in the Java Control
Panel. See “Configuring the Java Plug-In” on page 1-5 for instructions.
