방법

DB Link 설정 및 확인

Java Gateway 설정

tbJavaGW.zip 압축 해제

[tibero@kimmi bin]$ cd $TB_HOME/client/bin
[tibero@kimmi bin]$ unzip tbJavaGW.zip

Java Gateway 설정

DATABASE를 POSTGRESQL로 설정합니다. 
(default port : 9093, 설정 변경이 필요하다면 LISTNER_PORT 수정)

[tibero@kimmi bin]$ cd $TB_HOME/client/bin/tbJavaGW
[tibero@kimmi tbJavaGW]$ vi jgw.cfg
# Target database
DATABASE=POSTGRESQL

# Datasource class name for target database
# use with DATABASE=JDBC30 option.
#DATASOURCE_CLASS_NAME=com.tmax.tibero.jdbc.ext.TbDataSource
DATASOURCE_CLASS_NAME=org.postgresql.Driver

# XA datasource class name for target database
# use with DATABASE=JDBC30 option.
#XA_DATASOURCE_CLASS_NAME=com.tmax.tibero.jdbc.ext.TbXADataSource

# Listener port
LISTENER_PORT=9093

# Initial thread pool size
INIT_POOL_SIZE=10

# Max thread pool size
MAX_POOL_SIZE=100

# Max cursor cache size per thread
MAX_CURSOR_CACHE_SIZE=100

# Gateway Encoding-"ASCII", "EUC-KR", "MSWIN949", "UTF-8", "UTF-16", "SHIFT-JIS"
ENCODING=UTF-8

# Max length for Types.LONGVARCHAR
MAX_LONGVARCHAR=4K

# Max length for Types.LONGRAW
MAX_LONGRAW=4K

 

PostgreSQL JDBC 업로드

jdk 버전에 맞는 JDBC를 사용합니다. (다운로드 경로 : https://jdbc.postgresql.org/download/)

[tibero@kimmi tbJavaGW]$ cd $TB_HOME/client/bin/tbJavaGW/lib
[tibero@kimmi lib]$ ls -alrt

tbgw 수정

postgresqljdbc 인자 값에 2.1.3에서 업로드한 jar 파일을 입력합니다. 그리고 java 실행 인자에 $postgresqljdbc를 추가합니다.

[tibero@kimmi lib]$ cd $TB_HOME/client/bin/tbJavaGW
[tibero@kimmi lib]$ vi tbgw
