{true | false}
For DB2 UDB 8.1, the native DB2 batch mechanism is used. This
property determines whether certain restrictions are enforced to facilitate
data conversions as follows:
● false — The methods used to set the parameter values of a batch
operation performed using a PreparedStatement must match the
database data type of the column the parameter is associated with.
This is because DB2 servers do not perform implicit data conversions.
● true — This restriction is removed; however, parameter sets may not
be executed in the order they were specified.
The default is false.
{true | false}
This property value determines behavior as follows:
● true — Synonyms are included in the result sets returned from the
DatabaseMetaData.getColumns method.
● false — Synonyms are omitted from result sets.
The default is true.
This property is only applicable for DB2 UDB 7.1 and 7.2, DB2 OS/390,
and DB2 iSeries. This property is ignored for DB2 UDB 8.1. The driver
always returns synonyms for the DatabaseMetaData.getColumns method
when connected to DB2 UDB 8.1.

DB2
The DB2 schema to use for catalog functions. The value must be the name
of a valid DB2 schema.
The default is SYSCAT for DB2 UDB, SYSIBM for DB2 OS/390, and
QSYS2 for DB2 iSeries.
To improve performance, views of system catalog tables can be created in
a schema other than the default catalog schema. Setting this property to a
schema that contains views of the catalog tables allows the driver to use
those views. To ensure that catalog methods function correctly, views for
specific catalog tables must exist in the specified schema. The views that
are required depend on your DB2 database.
