OfflineUse offline mode to get the data from the cache instead of the live source.
CacheMetadataThis property determines whether or not to cache the table metadata to a file store.

Miscellaneous

CharBitDataCcsidAn Int32 value used to indicate which CCSID is used to translate iDB2CharBitData and iDB2VarCharBitData types when the CharBitDataAsString property is set to true. This property is ignored when CharBitDataAsString is set to false.
TruncateStringThis property specifies whether to truncate characters when INSERT or UPDATE is executed with a string that exceeds the column size.
SchemaThe schema used by default.
BatchSizeThe maximum size of each batch operation to submit.
