Tivoli Netcool/OMNIbus 8.1.0 Fix Pack 8, 8.1.0-TIV-NCOMNIbus-FP0008

Download Description

The following defect solutions are included in this release:

IV70937
The nco_config command will remove the newline character on
triggers that contain comments after the "When" clause. This
causes the trigger to fail the syntax check. This problem has
been resolved.


IV72912
A "ping host" command from a Netcool Administrator on Windows
will hang the Administrator process. The problem has been
resolved in this fix pack.


IV79347
Probes intermittently failed to connect to the ObjectServer with
the following error message in the probe logfile: 'Error:
E-UNK-000-000: Server verification failure. Failure Code=1013.'
This has now been fixed.


IV82539
The SQL generated by nco_osreport for use by nco_dbinit specifies
'persistent' as the memstore type for all memstores to be
created. This problem has been fixed so that memstore type in
the generated SQL will be persistent, virtual, or temporary, to
match the memstore type in the ObjectServer.


IV83155
A SELECT query can return incorrect results when it contains a
clause which compares 2 aggregate functions.
The following is an example of a query which can return incorrect
results:

"select count(*) as CNT,Node, max(Severity) as MAX_SEV,
max(Tally) as MAX_TAL from alerts.status group by Node having
max(Tally) < max(Severity)"

The code has been modified to fix this issue.

IV83627
This fix-pack adds four new features to scope-based event
grouping automation.

1. The scope-based event grouping automation is now extended to
also clear childless synthetic parents created by the
analytics-based event grouping.

2. The scope-based event grouping is now updated to allow a user
to modify the ScopeIDParent Summary text in relation to the
number of affected subgroups present. Previously it was hardcoded
to say "X sites affected". Customers use different things to
subgroup by, which are not necessarily sites. This additional
property allows users to specify the label, other than "site".
The new property is called SEGScopeIDSitesAffectedLabel and has a
default value of "site".

3. The scope-based event grouping automation creates journal
entries with the underlying children events' details in them.
Previously it did this function only for synthetic parent events
created for scope-based event grouping. This function is now
extended to also perform the same journaling function for the
synthetic parent events created by the analytics-based event
grouping.

4. The following two properties control whether OwnerUID and
OwnerGID propagate from parent events to child events, or not.
SEGPropagateOwnerUID
SEGPropagateOwnerGID
A 0 means it does not, and a 1 means it does. This enhancement
adds a third value. A value of 2 for SEGPropagateOwnerUID means
that it propagates only OwnerUID if the child event is not owned
by anyone i.e. the child has an OwnerUID of 65534 (Nobody).
Similarly, a value of 2 for SEGPropagateOwnerGID means that it
propagates only OwnerGID if the child event is not owned by any
group i.e. the child has an OwnerGID of 0 (Public). This feature
also applies to any groups created by the Event Analytics based
event grouping.


IV84051
The following two triggers, which are part of the self-monitoring
solution, are now modified to drop the insertion of housekeeping
synthetic events from the collection layer into the aggregation
layer:
sm_top_nodes_insert
sm_top_nodes_reinsert
Housekeeping synthetic events were previously allowed to be
inserted into the aggregation layer and might result in large
numbers of warning level alerts in the ObjectServer. The
$OMNIHOME/etc/update81fp7to81fp8.sql file contains new versions
of these triggers.


IV84144
The MIB Manager code is now updated to stop the MIBManager
utility from going into a hard loop. Before this update, the
MIBManager utility might go into a hard loop when it processed a
MIB file that contained the following definition.
Unsigned32 ::=
Unsigned32 (0..4294967295)
The hard loop behavior no longer occurs.

IV84416
The table 'master.correlation_scopealias' table became obsolete
in the event grouping extension shipped with OMNIbus 8.1 FP 7.
The FP4 to FP 7 update script attempted to drop the table but
after the update script ran, the table still existed in the
ObjectServer.
The 'SEGUseSiteNamePrefix' and 'SEGUseSiteNameCustomText'
properties that were added in FP 7 were turned OFF by default in
the original FP4 to FP 7 update script. The default for both
these properties is that they should be turned ON.
The script is now fixed:
'$NCHOME/omnibus/extensions/eventgrouping/update/update81fp4to81fp7/update81fp4to81fp7_aggregation.sql'.


IV84442
The ObjectServer is now modified to prevent high profiling times
that were previously caused by IDUC v1 clients not retrieving
change sets in a timely fashion. Now the IDUC v1 IBM Tivoli
Network Manager gateways and native event lists are no longer
automatically registered for notification of changes within the
alerts.journal table.


IV84621
Issuing the command 'flush iduc' from a SQL trigger can cause the
ObjectServer to terminate. Clients which issue 'flush iduc'
directly are not impacted.


IV84632
In response to RFE 18860, it is now possible for a probe to
failover/failback between an ObjectServer pair where the primary
server and backup server have schemas that differ from each
other. Previously the probe had to be stopped/restarted in order
to adapt to a new schema. This implementation extended the work
that was done for APAR IV75451 which was delivered in Tivoli
Netcool/OMNIbus 8.1.0 Fix Pack 4, 8.1.0-TIV-NCOMNIbus-FP0004.

Similarly as for APAR IV75451, the following schema differences
can be successfully handled:
* The addition of new fields added to any position in the schema.
* The complete removal of fields from the schema.
* Fields in the schema that have changed their order.
* Fields whose data types have changed. Existing values will be
converted if possible, otherwise a default value will be
populated.
* Fields that have been renamed will be treated as a new column.
The previous name will be treated as a field that has been
removed.
