Java Universal Driver

bull Significant reengineering of Java support for DB2 Connect CAE and DB2 for OS390 and zOS client softwarendash Uses DRDA protocols for all client communication

ndash Eliminates DB2RA and net driver protocols

ndash Traditional DB2 client configuration (CCA) is optional

ndash Much better handling of different clientserver software levels

ndash Improved DB2 Connect consistencyperformance

ndash much higher percentage of common code

ndash fewer unique code paths for specific hardware configurations

ndash Several significant improvements to DRDA

ndash support for long SQL names and statements

ndash DRDA query block sizes can now be up to 2M bytes

ndash rely on server-supplied stored procedures for SQL error messagesdatabase metadata etc

ndash many internal performance improvements

SQLJ usage is increasing

bull Static SQL performance for Java applicationsndash less code written by the application programmer

ndash resulting code is easier to maintain

ndash significant performance advantage over JDBC

ndash Static SQL authorization model

bull Provides Java with a stronger authorization modelndash Monitoringmanageability

ndash static SQL packages for accountingmonitoring

bull Static SQL locks in access path so that access path changes dont occur without a conscious choice

IBM Software Group | DB2 Information Management Software

JDBC vs SQLJ example

bull Retrieve a single row from DB2bull SQLJ

sql [con] SELECT ADDRESS INTO addr FROM EMP WHERE NAME=name

bull JDBCjavasqlPreparedStatement ps = conprepareStatement(SELECT ADDRESS FROM EMP WHERE NAME=)pssetString(1 name)javasqlResultSet names = psexecuteQuery()namesnext()addr = namesgetString(1)namesclose()

bull -- portable across platforms and DBMSsbull -- compilebind time schema checkingbull -- static SQL performance and authorizationbull -- concisebull -- strong typing
