Tips for Improved Performance
This section contains tips to help you improve performance of the HPOM
Java-based operator GUI.
Identifying Logged-on Java GUI Users
Before stopping the HP Operations management server or the database
processes for longer periods of time, it can be helpful to identify the
HPOM operators who are currently logged into the Java GUI, and notify
them of the upcoming downtime.
To find out who is currently logged into the Java GUI, start the following
tool:
/opt/OV/contrib/OpC/listguis -java
The output lists the number of open Java GUIs, the operator names and
the GUI hostnames. You can then either ask the operators to exit from
the Java -based GUI, or kill the opcuiwww processes.
About Security Exception Warnings
If you receive a security exception warning when trying to run the Java
GUI as an applet in a web browser, the security file identitydb.obj has
not been downloaded in binary mode.
To download the security file identitydb.obj in binary mode, follow
these steps.
1. Open the file /opt/OV/httpd/conf/mime.types, and add the
following line:
application/x-javakey obj
2. As user root, restart your Apache web server by entering:
/opt/OV/httpd/bin/apachectl restart
3. Download the file identitydb.obj again.
