Application Programming Guide and Reference for Java
Specifies how often, in seconds, global transport pool statistics are written to
the file that is specified by dumpPoolStatisticsOnScheduleFile. The global
transport object pool is used for the connection concentrator and Sysplex
workload balancing.
The default is -1. -1 means that global transport pool statistics are not written.
This property does not have a setXXX or a getXXX method.
Specifies the name of the file to which global transport pool statistics are
written. The global transport pool is used for the connection concentrator and
Sysplex workload balancing.
If dumpPoolStatisticsOnScheduleFile is not specified, global transport pool
statistics are not written.
This property does not have a setXXX or a getXXX method.
Specifies the amount of time in seconds that an unused transport object stays
in a global transport object pool before it can be deleted from the pool.
Transport objects are used for the connection concentrator and Sysplex
workload balancing.
The default value for maxTransportObjectIdleTime is 60. Setting
maxTransportObjectIdleTime to a value less than 0 causes unused transport
objects to be deleted from the pool immediately. Doing this is not
recommended because it can cause severe performance degradation.
This property does not have a setXXX or a getXXX method.
Specifies the maximum amount of time in seconds that an application waits for
a transport object if the maxTransportObjects value has been reached. Transport
objects are used for the connection concentrator and Sysplex workload
balancing. When an application waits for longer than the
maxTransportObjectWaitTime value, the global transport object pool throws an
SQLException.
The default value for maxTransportObjectWaitTime is -1. Any negative value
means that applications wait forever.
This property does not have a setXXX or a getXXX method.
Specifies the lower limit for the number of transport objects in a global
transport object pool for the connection concentrator and Sysplex workload
balancing. When a JVM is created, there are no transport objects in the pool.
Transport objects are added to the pool as they are needed. After the
minTransportObjects value is reached, the number of transport objects in the
global transport object pool never goes below the minTransportObjects value
for the lifetime of that JVM.
The default value for minTransportObjects is 0. Any value that is less than or
equal to 0 means that the global transport object pool can become empty.
This property does not have a setXXX or a getXXX method.
