2 개요오라클과티베로에서 JDBC 를통해접속한세션을구분할수있도록 JDBC 접속시 ConnectionProperties 를통해구분자를넣어줄수있다. 하나의 Node 에다수의 WAS 가있을경우 DB 에서 Session Kill 등의동작수행시원하는 Session 을선택할수있다. 사용하기 JEUS 에서설정방법 1 Oracle JEUSMain.xml 파일에다음항목을추가한다. <database> <vendor>oracle</vendor> <export-name>orads</export-name> <data-source-class-name>oracle.jdbc.pool.oracleconnectionpooldatasource</data-source-classname> <data-source-type>connectionpooldatasource</data-source-type> <database-name>ora11g</database-name> <port-number>1521</port-number> <server-name> </server-name> <user>scott</user> <password>tiger</password> <name>drivertype</name> <type>java.lang.string</type> <value>thin</value> <name>connectionproperties</name> <type>java.util.properties</type> <value>v$session.program=was1_orads</value> <connection-pool> <pooling> <min>2</min> <max>20</max> <period>500000</period> </pooling> <wait-free-connection> <enable-wait>true</enable-wait> <wait-time>60000</wait-time> </wait-free-connection> <check-query>select 1 FROM DUAL</check-query> <check-query-period>120000</check-query-period> 2

3 </connection-pool> </database> 위의빨간부분과같이 ConnectionProperties 에 v$session.program 으로정의해주면된다. DB 쪽에서다음과같은 SQL 문을통해서확인이가능하다. SQL> select username, program, status, osuser, machine from v$session where username='scott' order by program; USERNAME PROGRAM STATUS OSUSER MACHINE SCOTT JDBC Thin Client INACTIVE ozke901 kkam SCOTT JDBC Thin Client INACTIVE ozke901 kkam SCOTT was1_orads INACTIVE ozke901 kkam SCOTT was1_orads INACTIVE ozke901 kkam SQL> 해당설정을하지않은경우는 PROGRAM 이 JDBC Thin Client 로나온다. 만약 v$session 의조회권한이없을시 sys or system 계정에서다음명령을통해권한을부여해주면확인이가능하다. SQL> grant select on v_$session to scott; v$session 이아닌 v_$session 에권한을부여할수있다. 2 Tibero JEUSMain.xml 파일에다음항목을추가한다. <database> <vendor>tibero</vendor> <export-name>tbds3</export-name> <data-source-class-name> com.tmax.tibero.jdbc.ext.tbconnectionpooldatasource </data-source-class-name> <data-source-type>connectionpooldatasource</data-source-type> <database-name>tibero</database-name> <port-number>8629</port-number> <server-name> </server-name> <user>tibero</user> <password>tmax</password> <name>connectionproperties</name> 3

DB 쪽에서다음과같은 SQL 문을통해서확인이가능하다.

5 Tibero 의경우는 JDBC Driver 버전이 Tibero 5 rev 이상, Tibero 5 이상에서사용이가능하다. 버전확인은다음명령을통해확인할수있다. 1) JDBC Driver 버전확인 $ java -jar tibero5-jdbc.jar Tibero JDBC Driver 5.0 (Rev.68181M) 2) DB 버전확인 $ tbboot -v Tibero 5 (Build 68328, DB 5.0) 드라이버버전과 DB 버전모두조건을만족해야사용이가능하다. 다음과같은에러가발생한다면버전을확인해보기바란다.

Oracle 의경우는 ConnectionProperties 에설정된 user, password 를무시하고 <user>, <password> 또는 로 user, password 를설정해야만 DB 로세션을생성할수있다. 이두가지설정중하나라도없이 ConnectionProperties 에 user, password 를설정할경우에러가발생한다. Tibero 의경우는 ConnectionProperties 에설정된값을무시하지는않지만혼용하여사용할경우최종적으로 setting 된값이적용되기에순서를주의해서사용해야한다. ConnectionProperties 의 <value>user=sys,password=tibero,program_name=was1_tbds</value> 와 <user>tibero</user> 를동시에쓸경우나중에쓴값이적용되고이는 JDBC Spec 에어떤방식을사용하라고명시된것이없다.

CASE #3 의경우는 sys 유저의 password 를 tmax 로입력한것과같아서에러가발생한다. 가능한 ConnectionProperties 에 user, password 를명시하지않을것을권고한다.
