详细的步骤如下：

1.在环境变量的path中加入java的home目录：
%ORACLE_HOME%jdkbin
or
C:oracleproduct10.2.0db_1jdkbin

2.切换到isqlplus 的configure目录
C:>cd
C:>CD C:oracleproduct10.2.0db_1oc4jj2eeisqlplusapplication-deploymentsisqlplus

3.进入JAZN命令行并授权给admin这个default的isqlplus管理员帐号
C:oracleproduct10.2.0db_1oc4jj2eeisqlplusapplication-deploymentsisqlplus>java -Djava.security.properties=C:oracleproduct10.2.0db_1/sqlplus/admin/ip
lus/provider -jar C:oracleproduct10.2.0db_1/oc4j/j2ee/home/jazn.jar -user "iSQL*Plus DBA/admin" -password "welcome" -shell
JAZN:> help

cd ls set pwd help
mkdir rm man clear

JAZN:> listusers
iSQL*Plus DBA/admin

JAZN:> grantrole webDba "iSQL*Plus DBA" admin
JAZN:> listusers
iSQL*Plus DBA/admin
JAZN:> listusers "iSQL*Plus DBA"
admin
JAZN:> exit
JAZN:>

4.重新启动isqlplus
C:oracleproduct10.2.0db_1oc4jj2eeisqlplusapplication-deploymentsisqlplu
