Each ObjectServer property has a default value. In an unedited properties file, all

properties are set to the default values. At the top of the file, a list of the properties

with their default values, data types, and descriptions is provided, to act as a

reference. These properties are commented out with a number sign (#) at the

beginning of the line. Below the list of commented-out properties, another list of

properties with their default values is provided for editing purposes, if required.

Note: If you are running the ObjectServer in UTF-8 encoding on Windows, you

must also save the ObjectServer properties file in UTF-8 encoding.

Specifying ObjectServer properties

You can change the settings for ObjectServer properties in one of the following

ways:

v Edit the properties file and change the value of the required properties. Change

the entries below the commented-out list of properties. When you make changes

to the properties in the properties file, the changes do not take effect until you

restart the ObjectServer.

v Run the ALTER SYSTEM SET command from the SQL interactive interface.

v From the Netcool/OMNIbus Administrator interface, use the System menu

button and the Properties option to display the properties and edit their values.

When you use the ALTER SYSTEM SET command or Netcool/OMNIbus

Administrator to change the ObjectServer properties, changes to some of the

properties do not take effect until you restart the ObjectServer. For information

about viewing the properties that require an ObjectServer restart, see the list of

Tips that follows.

Whenever you change the ObjectServer property values by using the ALTER

SYSTEM SET command or Netcool/OMNIbus Administrator, a list of properties is

added at the bottom of the properties file to reflect your changes. As a result,

multiple entries for a property can exist within a file. The last entry for a property

takes precedence over any earlier entries.

Tips for viewing information about ObjectServer properties:

v You can query the catalog.properties table to view information about

ObjectServer properties. For example, to retrieve a list of properties that cannot

be modified, enter the following query in the SQL interactive interface:

select PropName from catalog.properties where IsModifyable=FALSE;

v Changes to some ObjectServer properties do not take effect until you restart the

ObjectServer. To retrieve a list of these properties, enter the following query:

select PropName from catalog.properties where IsImmediate=FALSE;

v You can also view information about the ObjectServer properties from the

Netcool/OMNIbus Administrator interface.

Specifying ObjectServer command-line options

When running the ObjectServer by using the nco_objserv command, you can

specify a set of command-line options. You can override both the default value and

the properties file value by changing the property value from the command line.

The command-line options for the ObjectServer use the following format:

nco_objserv [ -option [ value ] ... ]

Table 2. ObjectServer properties and command-line options (continued)

Property Command-line option Description

AlertSecurityModel integer -alertsecuritymodel integer This property determines whether group row

level security is enforced in the event list. By

default, group row level security is disabled (0).

In this case:

v A member of the Normal group can modify a

row that is assigned to themselves or the

nobody user.

v A member of the Administrator group can

modify a row that is assigned to themselves,

the nobody user, or a member of the Normal

group.

If the AlertSecurityModel property is enabled

(1), only users in the group that owns the row

can modify the row. In this case, a member of

the Normal or Administrator group can modify

a row that is assigned to a group of which they

are a member.

A member of the System group can always

modify any row.

For more information about system and default

groups, see the IBM Tivoli Netcool/OMNIbus

Installation and Deployment Guide.

AllowConnections TRUE | FALSE -disallowconnections Specifies whether non-root users can connect to

the ObjectServer. If FALSE, no new connections

to the ObjectServer are allowed. The default is

TRUE.

AllowISQL TRUE | FALSE -disallowisql Specifies whether connections to the

ObjectServer are allowed using the SQL

interactive interface. If FALSE, no user can

connect using nco_sql. The default is TRUE.

If TRUE, this can be enabled for each user using

Netcool/OMNIbus Administrator.

AllowISQLWrite TRUE | FALSE -disallowisqlwrite Specifies whether modifications to the

ObjectServer are allowed using the SQL

interactive interface. If FALSE, no user can

modify the ObjectServer using nco_sql. The

default is TRUE.

If TRUE, this can be enabled for each user using

Netcool/OMNIbus Administrator.

AllowTimedRefresh TRUE |

FALSE

-allowtimedrefresh TRUE |

FALSE

This property determines whether the user can

enable timed refresh in the Refresh tab of the

Event List Preferences window. If TRUE, the

event list preferences can be set to allow alert

information to be updated at a specified interval

rather than waiting for notification of updates

from the ObjectServer. The default is FALSE.

If FALSE, the timed refresh check box is grayed

out in the Refresh tab of the Event List

Preferences window and timed refresh is

disabled.

Table 2. ObjectServer properties and command-line options (continued)

Property Command-line option Description

Auto.Debug TRUE | FALSE -autodebug TRUE | FALSE If TRUE, automation debugging is enabled. The

default is FALSE.

Auto.Enabled TRUE | FALSE -autoenabled TRUE | FALSE If TRUE, automations are enabled. The default is

TRUE.

Auto.StatsInterval integer -autostatsinterval integer Specifies the interval in seconds at which the

automation system collects statistics. The default

is 60.

Statistics are gathered unless the -autoenabled

command-line option is set to FALSE, which

disables all automations.

BackupObjectServer TRUE |

FALSE

-backupserver Provides failback capability with desktop clients,

probes, the proxy server, and the ObjectServer

Gateway. The default is FALSE; the desktop

clients, probes, the proxy server, and gateways

are assumed to be connected to a primary

ObjectServer. When TRUE, the desktop clients,

probes, the proxy server, and gateways are

made aware that they are connected to the

backup ObjectServer in a failover pair. If this is

the case, the desktop clients, probes, the proxy

server, and gateways will automatically check

for the recovery of the primary ObjectServer in

the failover pair and switch back (fail back)

when it has restarted.

ClientHeartbeatDisable TRUE |

FALSE

-clienthbdisable TRUE | FALSE Disables the client heartbeating system if set to

TRUE. This causes a connected client to time out

if the ObjectServer is busy - for example, during

a gateway resynchronization or an automation.

The default FALSE setting enables heartbeating,

and prevents invalid and unnecessary client

timeouts. If the ObjectServer is active but busy,

this setting causes the ObjectServer to send a

pop-up message to a connected client, with

details of the type of processing in progress.

ClientHeartbeatRate integer -clienthbrate integer Sets the rate in seconds of a client heartbeat.

This rate defines how long a client should wait

for a response from the ObjectServer before

timing out. The default value is 10.
