Troubleshooting on Managed Nodes
This section includes descriptions of specific problems that may occur on
the ITO managed nodes and provides a solution.
1. Identify the ITO version installed on the management server by
looking at the /opt/OV/bin/OpC/install/opcsvinfo file on the
management server.
Problem Ungraceful abort of the ITO GUI leaving some GUI processes still
running
Description You receive the error message The user is already logged on.
(50-17), when logging on to ITO after the ITO GUI has crashed while
users were still logged on.
Solution Some GUI processes may still be running; check for the following
processes and kill them:
opcuiadm
opcuiop
opcdispr
ovw
If these processes are not running, but you still receive the error message,
delete the entry for logged-on operators from the ITO database:
su - oracle
svrmgrl
connect internal;
select * from opc_op.opc_op_runtime;
To delete the entry for a specific user (currently logged on):
delete from opc_op.opc_op_runtime where name =
‘<username>’;
To delete the entry for a all users (currently logged on):
delete from opc_op.opc_op_runtime;
commit;
exit
exit
