oracle用户，定时插入数据脚本
脚本如下
#!/bin/bash
#---Insert 500 pieces of data into the database---
sqlplus / as sysdba << EOF
conn test01/shuyi123
select count(*) from test01;
insert into jd_test01 value( select rownum as id,rownum+10 as task_id,dbms_random.string('x', 40) as server_uuid,dbms_random.string('x',40) as proxy_uuid,dbms_random.string('x',40) as repo_uuid from dual connect by level<=500);
select count(*) from test01;
commit;
exit;
EOF
定时任务日志：提示sqlplus 命令未找到

/oradata/insert_data.sh:行7: sqlplus: 未找到命令
究其原因，是因为定时任务在执行脚本的时候读取不了oracle用户环境变量，找不到sqlplus命令
所以在脚本中加入下面一行：
source /home/oracle/.bash_profile
定时任务即可正常执行。
