Software Maintenance on Managed Nodes
Installing or Updating ITO Software Automatically
a. In the ITO Application Bank window, select Actions:
Add ITO Application.
b. Enter a name in the Application Name field, and enter the
following in the Application Call field:
/opt/OV/bin/OpC/utils/opcnode -chg_commtype \
comm_type=COMM_DCE_UDP node_list="$OPC_NODES"
You can also choose COMM_DCE_TCP instead of COMM_DCE_UDP.
Note, however, that COMM_DCE_UDP is recommended.
c. Select Start on Management Server, and specify user root
to execute the application because opcnode must be called
with root permissions. Click on [OK].
opcnode is added as an application to the ITO Application
Bank.
d. Select the nodes for which you want to change the
communication type in the ITO Node Bank or any other node
hierarchy.
e. In the ITO Application Bank, double-click the opcnode
symbol to execute the application.
The communication type changes for all selected nodes. Verify this
by opening the Node Advanced Options window, or calling
opcnode -list -nodes. See also the man page opcnode(1M) for
more information.
4. Use the Install / Update ITO Software and Configuration
window to update the ITO agent software.
Depending on the communication type you have selected in the
previous step, ITO automatically selects the appropriate agent fileset
during the agent software installation.
