Oracle JDBC for RdbNative Driver

OracleRdb

Java Programnative driver

Dynamic SQL

• Purpose of this driver– Environment type Java application

and Java application as a middle tier.• JDBC call is translated to dynamic

SQL• Features

– JAVA applet can not be used.– Performance is best.

Java Socket

Rdb Thin ServerTCP/IP

• Thin driver connects to OracleRdb via JAVA sockets usingTCP/IP

• Features– No client libraries need to be

installed.• 100% JAVA

– only TCP/IP protocol issupported.

7

Oracle JDBC for RdbThin Server

• Multi-threaded server• Listens to single port• Single process• Synchronization needed at Rdb interface

may limit concurrency

Oracle JDBC for RdbPool Server

• Distributes connection requests• Pool of available Thin servers• Single Node:port address• Thin Server may be local/remote to pool

server• Better concurrency• NOT connection pooling

V7.1.3 release

• Multi-Process Server• XML –based configuration file• SQL/Services Manager server start and

close• More Controller features• Auto-start and keep alive with pool

servers

20

V7.1.3 release (Cont.)

• Secure Socket support (SSL)• DEC_KANJI , DEC_HANZI support is

still undergoing testing

21

Oracle JDBC for RdbMulti-Process Server

• Multi-threaded server• New sub-process started for each

connection• Single Node:port address• Better concurrency as multiple process

used, no synchronization needed

XML–based configurationfile

• *.CFG still supported• *.XML provides more features• Single configuration file for all servers or have

multiple configuration files – your choice• Other characteristics

– Session information– Databases– DEFAULT server characteristics

Oracle JDBC for RdbController features

• Start / Stop / Open /Close / Show server• Watch server ( Trace log sent to

controller console)• Poll of active servers on network ( using

Multicast)• Stop Client – Stop all Clients – Stop

Clients in database

34

Auto-start & Auto-restart

• Available only in conjunction with poolserver

• Thin servers auto-start on Pool serverstartup

• Also servers close down when Pool servercloses

• Auto-restart and keep alive timer

35

Asian Character Sets

• Previously a problem asUNICODE/Asian conversion libraries onVMS not compatible with server sharedimage.

• Now using JAVA to do conversions,more character sets supported by drivers

• Still undergoing testing

36

SSL Support

• Client/Server communication may use SecureSocket Layer sockets

• New SSL type servers– RdbThinSSL– RdbThinMPSSL– RdbThinPoolSSL

• Startup may take longer – handshake takes time• You can choose security aspects of SSL

SSL support ( Cont.)

• Server needs SSL information<server name="DEFAULTSSL" type="RdbThinSrvSSL" ssl.default="false" ssl.context="TLS" ssl.keyManagerFactory="SunX509" ssl.keyStoreType="jks" ssl.keyStore="rdbjdbcsrv.kst" ssl.keyStorePassword="CHANGETHIS" ssl.trustStore="rdbjdbcsrv.kst" ssl.trustStorePassword="CHANGETHIS“/>

RdbThinSrvSSL :New type of

Server

38

SSL support ( Cont.)

• Client needs SSL information• Use Properties block on connection

SSL support ( Cont.)Properties info = new Properties();info.put("user", user);info.put("password", password);info.put("tracelevel", traceLevel);info.put("ssl", "true");info.put("ssl.default", "false");info.put("ssl.context", "TLS");info.put("ssl.keyManagerFactory", "SunX509");info.put("ssl.keyStoreType", "jks");info.put("ssl.keyStore", "rdbjdbccli.kst");info.put("ssl.keyStorePassword", "CHANGETHIS");info.put("ssl.trustStore", "rdbjdbccli.kst");info.put("ssl.trustStorePassword", "CHANGETHIS");Connection conn = DriverManager.getConnection( “jdbc:rdbThin://bravo:1755/my_db_dir:pers",info);

40

Itanium

• Kit built with Native build of images• JAVA is JAVA is JAVA. No changes

needed for JARs• NO change needed to Oracle JDBC for

Rdb source code• Thin Server running on IA64• Thin Client running on IA64
