"OFF" or "0"
Parallel processing is disabled.
If this property is not set, no value is sent to the server. The value for the
PDQPRIORITY environment variable is used.
PSORT_DBTEMP
Specifies the full path name of a directory in which the database server writes
temporary files that are used for a sort operation. The data type of this
property is String.
If this property is not set, no value is sent to the server. The value for the
PSORT_DBTEMP environment variable is used.
PSORT_NPROCS
Specifies the maximum number of threads that the database server can use to
sort a query. The data type of this property is String. The maximum value of
PSORT_NPROCS is "10".
If this property is not set, no value is sent to the server. The value for the
PSORT_NPROCS environment variable is used.
STMT_CACHE
Specifies whether the shared-statement cache is enabled. The data type of this
property is String. Possible values are:
"0"
The shared-statement cache is disabled.
"1"
A 512 KB shared-statement cache is enabled.
If this property is not set, no value is sent to the server. The value for the
STMT_CACHE environment variable is used.
dumpPool
Specifies the types of statistics on global transport pool events that are written,
in addition to summary statistics. The global transport pool is used for the
connection concentrator and Sysplex workload balancing.
The data type of dumpPool is int. dumpPoolStatisticsOnSchedule and
dumpPoolStatisticsOnScheduleFile must also be set for writing statistics before
any statistics are written.
You can specify one or more of the following types of statistics with the
db2.jcc.dumpPool property:
v DUMP_REMOVE_OBJECT (hexadecimal: X'01', decimal: 1)
v DUMP_GET_OBJECT (hexadecimal: X'02', decimal: 2)
v DUMP_WAIT_OBJECT (hexadecimal: X'04', decimal: 4)
v DUMP_SET_AVAILABLE_OBJECT (hexadecimal: X'08', decimal: 8)
v DUMP_CREATE_OBJECT (hexadecimal: X'10', decimal: 16)
v DUMP_SYSPLEX_MSG (hexadecimal: X'20', decimal: 32)
v DUMP_POOL_ERROR (hexadecimal: X'80', decimal: 128)
To trace more than one type of event, add the values for the types of events
that you want to trace. For example, suppose that you want to trace
DUMP_GET_OBJECT and DUMP_CREATE_OBJECT events. The numeric
equivalents of these values are 2 and 16, so you specify 18 for the dumpPool
value.
The default is 0, which means that only summary statistics for the global
transport pool are written.
This property does not have a setXXX or a getXXX method.
