Tuning, Troubleshooting, Security, and Maintenance
Performance Tuning
Suppress the appearance of the ITO Alarm Severity symbol in the HP
OpenView submaps by changing the ITO app-defaults file. Set the
line Opc.statusPropOnAllNodes in the file
/opt/OV/lib/X11/app-defaults/<language>/Opc to False.
The default setting is True.
For details about HP OpenView Network Node Manager performance
tuning, refer to the corresponding part of the "Configuration" chapter in
the HP OpenView Network Node Manager Administrator's Reference. See
also the HP OpenView SNMP Management Platform Performance and
Configuration Guide.

Improving Database Performance

Split the database over several disks as described in your Oracle
database manuals.
Periodically reorganize the database, by running opcdbreorg (1M).
This frees unused pages as well as restructuring the index tables. For
more details, see the opcdbreorg (1M) man page.
In addition, you should periodically tune the database by running
optimizedb followed by sysmod. Note, however, that during this
process, applications cannot work on the database.
For details about an Oracle database, see the documentation supplied
with the database and the online documentation in
/opt/OV/ReleaseNotes/opc_db.tuning.

Improving ITO's Performance

To both increase the speed of the GUI and to reduce the memory needed

Message Browsers:
Specify more precise filters (message conditions) for capturing
messages.
Specify more (local) automatic actions with automatic message
acknowledgment after successful operation.
Download the history database of acknowledged messages more
often.
