Improving the Startup Performance of the Motif GUI
To increase the startup speed of the OVO Motif-based operator GUI, do
the following:
❏ Disable Logo
If you have a slow network connection between the OVO
management server and your X display (for example ISDN), consider
disabling the OVO logo.
This can be done by setting a resource in the OVO X resources file
/opt/OV/lib/X11/app-defaults//OpC:
Opc.showLogo
If set to False, the OVO login screen and the Help About window do
not display the OVO logo. The default is True. For details, see the
man page opc(1).
❏ Use Cache
In environments with many managed nodes, the operator Motif GUI
can take some time before it is fully loaded.
You can improve the startup performance by starting the Motif GUI
with the following option:
opc -use_cache
If you use this option, the Motif GUI uses a cache file to retrieve the
current status and configuration of the OVO objects. The cache file is
updated when the Motif GUI is closed.
CAUTION Do not use the use_cache option if you are using NNM functionality
with OVO. Changes in the OVO Windows maps or the NNM object
database are not detected when running the operator GUI with the
use_cache option. This means that configuration changes through
NNM or other integrated applications, as well as manual changes in
the NNM object database, are not detected.
