数据库内连接会话超过参数配置,导致报错ORA-00020:maximum number of processes (500) exceeded同时sys用户无法正常登录
[oracle@test ~]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 4 13:05:22 2022

ERROR:
ORA-00020:maximum number of processes (500) exceeded
Enter user-name:
解决 ORA-00020 错误,加大processes的参数值即可,但是需要sys用户能够登录进行参数调整
通过加参数 “-prelim” 强制登陆数据库sqlplus -prelim / as sysdba

此时就可以正常关闭和开启数据库,进行参数调整
