mycat字符集gbk
oracle字符集gbk
原jdbc连接串：
base.jdbc.url=jdbc:mysql://127.0.0.1:3306/XXX?useUnicode=true&characterEncoding=gbk

mycat中不是乱码，如下：
06/26 14:45:19.609 WARN [BusinessExecutor1] (MultiNodeHandler.java:126) -error response from JDBCConnection [id=68,autocommit=true,pool=org.opencloudb.jdbc.JDBCDatasource@1dbc0e73, schema=hs_tatrade2, dbType=ORACLE, oldSchema=hs_tatrade2, packetId=-55, txIsolation=0, running=false, borrowed=false, host=null, port=-1, con=oracle.jdbc.driver.T4CConnection@12645708, respHandler=null, attachement=null, headerOutputed=false, modifiedSQLExecuted=false, startTime=1529975130206, lastTime=1529995519607, isSpark=false, processor=org.opencloudb.net.NIOProcessor@2558af45] err ORA-00942: 表或视图不存在
增加characterSetResults=gbk，如下：
base.jdbc.url=jdbc:mysql://127.0.0.1:3306/bomp_test?useUnicode=true&characterEncoding=gbk&characterSetResults=gbk
异常信息如下：

问题解决，mycat->oracle，比较尴尬，准备sharding-jdbc->oracle。
