KNOWN PROBLEMS
----------------------------------------------------------------------
- None.
UPGRADE STRATEGY
----------------------------------------------------------------------
- This release is compatible with the previous version. The following
configuration options must be updated manually after installation if
they were modified from the defaults.
[LOCAL_DIR]/conf/service/SnmpService.xml:
- listener.port
- listener.details.off
[LOCAL_DIR]/conf/TrapRules.hmf:
where the default [LOCAL_DIR] is /var/opt/HMF.
During an upgrade this file is replaced with the latest version.
Any custom modifications must be manullay added from the backup
file that is created during the upgrade process.
- The unit of the following configuration parameter in PerfdbService.xml
file has been changed from 'second' to 'minute':
- reporter.dataCollectionInterval
Follow these steps to manually update the value:
- Save a backup copy of [LOCAL_DIR]/conf/service/PerfdbService.xml.
- Edit the above PerfdbService.xml file, and change the value (in
seconds) on the following line to the equivalent value in minutes:
<property name="reporter.dataCollectionInterval" value="3600" type="int"/>
In the above example, the value need to be updated to 60 (minutes),
instead of 3600 (seconds).

VERSION/DATE: 1.7.0/2009-11-16
ENHANCEMENTS
----------------------------------------------------------------------
- Added support for Sun Ops Center 2.5.
- Events can be deleted after configurable retention period or after
exceeding the configurable maximum number of events.
- Added ProcessRule command-line utility, which can be used to add,
update, or delete a filter from a rule, or add a new rule, or mark
a rule as deleted.
- Added a search bar in the Event Viewer of Neuron Management Portal,
which can be used to search for events that match the given keyword(s).
- User can define event tag(s) for events in the Event Viewer of Neuron
Management Portal, which can be used to classify events.
- Added ReverseAcknowledge.sh script, which can be used with various
Neuron Integration solutions to remotely acknowledge Halcyon Neuron
Core events from 3rd-party management frameworks.
- Performance statistics are collected and stored for Halcyon Neuron
Core, Neuron Integration solutions, and Neuron modules.
- Added a new log file RequestAction.log to record the execution
history of rules.
BUG FIXES
--------------------------------------------------------------------

with proper metric type.
- The asset of events received from Sun Ops Center is properly matched
to an asset in Sun Ops Center.
KNOWN PROBLEMS
----------------------------------------------------------------------
- None.
UPGRADE STRATEGY
----------------------------------------------------------------------
- None. This release is compatible with the previous version.
======================================================================
VERSION/DATE: 1.6.0/2009-09-30
ENHANCEMENTS
----------------------------------------------------------------------
- Improved stability and user-experience.
- Events received are linked to an asset for the originating host,
device, agent, or Neuron Core service. The Neuron Event Viewer
contains new topology views which make locating events for a
particular asset much easier.
- Neuron Core creates a list of aliases for each host it detects.
Common aliases are short host names, host names including the
fully qualified domain name, or IP addresses. This information
is used to link an event to an asset.
- Assets for agents such as the Sun Management Center Agent or
Neuron Agent contain a link to their parent asset, i.e. the host
on which the agent is running.
- Events received from Sun Ops Center or via IPMI now contain
a unique id for deduplication. This virtually eliminates the
possibility of duplicate events from these sources.
- The Neuron Core database supports the definition of operations.
These can be added by the user in order to execute them manually
or automatically based on a schedule. An existing command-line
tool has been extended to allow addition of, updates to, and
removal of these operations. A new utility has been included
which can be used to execute operations.
- Improved look and feel of alert boxes.
- Event Viewer contains an improved mechanism for selecting
date and time values for the Time Received filter. Values
can also be entered directly.
- Events are logged by all Neuron adapters and modules when they
are installed or removed.
- All components of Neuron Core as well as Neuron adapters and
modules reuse existing configuration information upon
reinstallation.
- Message Logger also logs the name of the rule that caused the
execution of an action.
- Neuron Management Portal displays detailed version information
in the About box.
BUG FIXES
--------------------------------------------------------------------
- Display correct text when logging out from Neuron Management
Portal.
- Improved error handling in Neuron Management Portal in case no
response has been received from Neuron Core.
- Corrected ownership of files in the run-time directories.
- File name of exported and published performance data reports
contains name of report.
- Increased default graph size of published reports.
- Raw events are always deleted from the database. In case of an
error the event is logged to the PostgreSQL log of Neuron Core.
- Improved the robustness of stored procedures used by Neuron Core.
- The source asset of SNMP v1 traps received by Neuron Core is
set to the IP address of the originating host or its host
name (if resolvable).
- Message Gateway sends events to Neuron Core if it cannot read
data from its message cache file and creates a backup of the
message cache.
KNOWN PROBLEMS
----------------------------------------------------------------------
- None.
UPGRADE STRATEGY
----------------------------------------------------------------------
- None. This release is compatible with the previous version.
======================================================================
VERSION/DATE: 1.5.2/2009-09-18
BUG FIXES
--------------------------------------------------------------------
- Improved stored procedure add_asset for better error handling.
UPGRADE STRATEGY
----------------------------------------------------------------------
- None. This release is compatible with the previous version.
======================================================================
VERSION/DATE: 1.5.1/2009-09-04
BUG FIXES
--------------------------------------------------------------------
- Time Received filter in Event Viewer allows selection of date and
time.
UPGRADE STRATEGY
----------------------------------------------------------------------
- None. This release is compatible with the previous version.
======================================================================
VERSION/DATE: 1.5.0/2009-08-18
ENHANCEMENTS
----------------------------------------------------------------------
- Neuron Management Portal can now only be accessed using a secure
connection. All communication between the Neuron Management Portal
and Neuron Core is also using SSL for improved security.
- Neuron Agent assets are automatically added to the configuration
database when events from these agents are received.
- Neuron Agent assets can be viewed remotely through the Neuron
Management Portal's Neuron Agent Viewer
- Neuron Agent's performance data as gathered by the Agent's
Reporter module can now be extracted by Halcyon's Neuron Core.
- ActiveMQ has been updated to FUSE Message Broker version 8.3.0.4
for improved performance and stability.
- PostgreSQL database has been updated to version 8.4.0. Support for
the PostgreSQL extension dblink is now included on all platforms.
BUG FIXES
--------------------------------------------------------------------
- Numerous bug fixes that improve the stability and user-experience
of the product.
KNOWN PROBLEMS
----------------------------------------------------------------------
- None.
UPGRADE STRATEGY
----------------------------------------------------------------------
- Upgrading the configuration from the previous version is handled
automatically. However, due to changes in security and database
versions an existing database cannot be reused. Future upgrades
will be fully supported.
- If the previous version of Neuron Core was used to integrate with
Nueron agents (Neuron agents setup to send events to the Neuron
Core), then the following strategy needs to be followed:
1) Stop Neuron Core.
2) Stop all Neuron Agents that were integrated with the Nueron
Core.
3) Upgrade each Neuron Agent that was integrated with the Neuron
Core from version 3.0.0 to version 3.1.0.
4) Upgrade the Neuron Core to the current 1.5 version.
5) Start the Neuron Core.
6) Start each Neuron Agent integrated with the Nueron Core.
The upgrade must be carried out in this order to ensure that no
Neuron 3.0.0 Agent is integrated with the Neuron 1.5.0 Core. If
a Neuron 3.0.0 Agent has been integrated with the Neuron 1.5.0
Core, and is then upgraded to a 3.1.0 Agent, Neuron Core will
recognize it as a new agent, but will be unable to distinguish
which is valid.
======================================================================

KNOWN PROBLEMS
----------------------------------------------------------------------
- None.
UPGRADE STRATEGY
