Thread pools
Partition properties relevant to the configuration of this pool can be browsed and edited
in the Partition Properties dialog of a Partition displayed in the Borland Management
Console. For more information refer to Chapter 2, “Using Partitions.”
Configuration of the default thread pool is achieved through the partition
vbroker.properties configuration file. The necessary properties are automatically
configured in BES Partitions. The configuration file is located under /var/
domains//configurations//mos//adm/properties/
vbroker.properties, and they are described in the VisiBroker for Java Developer's
Guide.
Auxiliary thread pool
The auxiliary thread pool is used internally by a Partition to ensure that the default
thread pool is used exclusively for application requests, and to prevent issues such as
distributed deadlocks. The auxiliary thread pool is defined through configuration of a
VisiBroker server engine called aux_se.
Configuration of the auxiliary thread pool is achieved through the partition
vbroker.properties configuration file. The necessary properties are automatically
configured in BES Partitions. They are described in the following table.
Table 3.3
Auxiliary thread pool properties
Property Default value Description
vbroker.se.aux_se.host null Specifies the host name that can be used by
this server engine. The default value, null,
means use the host name from the system.
Host names or IP addresses are valid values.
vbroker.se.aux_se.proxyHost null Specifies the proxy host name that can be used
by this server engine. The default value, null,
means use the host name from the system.
Host names or IP addresses are valid values.
vbroker.se.aux_se.scms aux_tp Specifies the Server Connection Manager
name.

Socket
Specifies the type of Server Connection
Manager.
0 Specifies the maximum number of connections
to the server. The default value, 0 (zero),
indicates that there is no restriction.
0 Specifies the time in seconds that the server
uses to determine whether an inactive
connection should be closed.
IIOP
Specifies the type of protocol the listener is
using.
0 Specifies the port number used with the host
name property. The default value, 0 (zero),
indicates that the system will pick a random port
number.
0 Specifies the proxy port number used with the
proxy host name property. The default value, 0
(zero), indicates that the system will pick a
random port number.
1.2 This property can be used to resolve
interoperability problems with older VisiBroker
ORBs that cannot handle unknown minor GIOP
versions correctly. Valid values for this property
are 1.0, 1.1 and 1.2.
ThreadPool Specifies the type of thread dispatcher used in
the Server Connection Manager.
0 Specifies the minimum number of threads that
the Server Connection Manager can create.
