Время отклика выше, когда я вызываю процедуру в oracle через простой вызов Jdbc по сравнению с локальной средой

Я написал API, используя spring для вызова хранимой процедуры с типом таблицы в качестве входного параметра paremter и number out.Когда я называю это API, это занимает около 2 минут, чтобы получить результаты.Но когда я запускаю эту процедуру в среде оракула, она занимает не более 2 секунд.Я заметил, что на рукопожатие тратится больше времени.

Есть ли лучший способ улучшить мое решение и сократить время отклика API.

Примечание: размер orderList в моем случае не более 5.

Java Code 

public class getOrders(ApprovalAction approvalActionObj)
{ 
List<Orders> orderList= approvalActionObj.getApprovalQsType();

    SimpleJdbcCall jdbcCall = new 
    SimpleJdbcCall(jdbcTemplate).withProcedureName("XX_PROCEDURE")
    .withCatalogName("XX_PACKAGE").withoutProcedureColumnMetaDataAccess()
    .declareParameters(
    new SqlParameter("P_ORDER_ROLLUP", Types.ARRAY,"ALG_ORDER_TAB"),
    new SqlOutParameter("O_ERROR_MESSAGE", Types.NUMBER));
//Edited
jdbcCall.getJdbcTemplate().setNativeJdbcExtractor(new 
OracleJdbc4NativeJdbcExtractor());
Object[][] orderArray = new Object[ordersList.size()][2];   

for(int actionIndex = 0; actionIndex < ordersList.size(); actionIndex++) 
{

   ordersArray[actionIndex][0] = orderList.get(actionIndex).getId();
   ordersArray[actionIndex][1] = orderList.get(actionIndex).getType();
}
  Map<String, Object> orderResult=jdbcCall.execute(new 
  MapSqlParameterSource().addValue("P_ORDER_ROLLUP", new 
  SqlArrayValue(orderArray)));

Integer errorMsg = (String) orderResult.get("O_ERROR_MESSAGE"); 
}

DabaseConfigClass 

@Configuration
public class DataBaseConfig {
  private static final Log LOGGER = LogFactory.getLog(DataBaseConfig.class);
  @Autowired
  private Environment environment;
  @Bean(name = "jdbcTemplate")
  public JdbcTemplate jdbcTemplate() throws SQLException {
    OracleDataSource dataSource = new OracleDataSource();

    String url = environment.getProperty("spring.db.jdbc.url");
    String userName = environment.getProperty("spring.db.username");
    String password = environment.getProperty("spring.db.password");
    String driver = environment.getProperty("spring.db.driver-classname");

    dataSource.setUser(userName);
    dataSource.setPassword(password);
    dataSource.setURL(url);
    dataSource.setDriverType(driver);
    return new JdbcTemplate(dataSource);
    }
}

При реализации пула соединений со следующим DataBaseConfig выдается ошибка. 

@Configuration public class DataBaseConfig { 
  @Bean 
  public HikariDataSource getDataSource() { 

     HikariConfig config = new HikariConfig(); 
     HikariDataSource ds; 
     config.setDriverClassName(className); 
     config.setJdbcUrl(Url); 
     config.setUsername(userName); 
     config.setPassword(passWord); 
     config.addDataSourceProperty("cachePrepStmts", "true"); 
     config.addDataSourceProperty("prepStmtCacheSize", "250"); 
     config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048"); ds = new 
     HikariDataSource(config);  
     return ds; 
    } 
  }

uploadCall.getJdbcTemplate().setNativeJdbcExtractor(new 
OracleJdbc4NativeJdbcExtractor());

Необходимо добавить этот кусок кода для ошибки приведения.

Наконец-то, после многих поисков и реализации нескольких сценариев.Я нашел одну вещь, которая должна быть реализована для повышения производительности при использовании типа таблицы;

1) Нам нужно использовать дескриптор массива и дескриптор структуры для создания типа таблицы вместо массива объектов. 

OracleConnection connection = uploadCall.getJdbcTemplate().getDataSource().getConnection().unwrap(OracleConnection.class);
StructDescriptor desc1=StructDescriptor.createDescriptor("XX_TYP",connection);
ArrayDescriptor desc2=ArrayDescriptor.createDescriptor("XX_TAB",connection);
Object[] p1arrobj = new Object [uploadList.size()];
for(int i=0;i<orderList.size();i++)
{
    Object [] p1recobj = {orderList.get(i).getId(),orderList.get(i).getType()};
    STRUCT p1struct = new STRUCT(desc1,connection,p1recobj);
    p1arrobj[i]=p1struct;
}
ARRAY p1arr = new ARRAY(desc2,connection,p1arrobj);
