解决：
jdbc_driver_library 配置
ojdbc10.jar 是我在官网下载的驱动，启动还是找不到，然后我又换了一个ojdbc8.jar 还是不行。
最后去oracle数据库那台服务器上。找驱动（所在oracle机器的安装位置）
命令搜索： find / -name ojdbc8.jar
[root@xx ~]# find / -name "ojdbc8.jar"
/home/oracle/database/stage/ext/jlib/ojdbc8.jar
/home/oracle/ora_home/oracle/product/12.2.0/dbhome_1/inventory/Scripts/ext/jlib/ojdbc8.jar
/home/oracle/ora_home/oracle/product/12.2.0/dbhome_1/inventory/backup/2019-07-17_03-11-45PM/Scripts/ext/jlib/ojdbc8.jar
/home/oracle/ora_home/oracle/product/12.2.0/dbhome_1/jdbc/lib/ojdbc8.jar
找到对应哪个jar /home/oracle/ora_home/oracle/product/12.2.0/dbhome_1/jdbc/lib/ojdbc8.jar
然后把它拷贝到之前服务器上对应目录下。就启动成功了。
jdbc_driver_class配置
jdbc_driver_class=>"Java::oracle.jdbc.driver.OracleDriver"
