ORA-09925 Unable to create audit trail file

denglj

数据库：oracle11.2.0.4

系统：anolisos7.9

环境：系统中安装过11g数据库实例，同时也安装了19.3数据库软件.

问题描述：

在/u01/app/oracle/product/19.3.0/db_1目录下使用deinstall命令后，11g数据库状态显示正常，但连接报错ORA-09925，如下所示：

[oracle@leo~]$ cat .bash_profile

……

exportORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

#exportORACLE_HOME=$ORACLE_BASE/product/19.3.0/db_1

……

[oracle@leobin]$ pwd

/u01/app/oracle/product/11.2.0/db_1/bin

[oracle@leobin]$ ./sqlplus / as sysdba

异常原因：

无法创建审计文件，若以sysdba用户登陆数据库都会被强制审计，如果审计文件无法写入，肯定会有问题.

解决过程：

使用strings查看二进制spfile文件.

[oracle@leodbs]$ strings spfileorcl.ora

……

*.audit_file_dest='/u01/app/oracle/admin/orcl/adump'

……

[oracle@leodbs]$ ll /u01/app/oracle/admin/orcl/

ls:cannot access /u01/app/oracle/admin/orcl/: No such file or directory

发现该目录不存在，判断为deinstall19c时该目录被删除.

新建该目录后，连接无异常.

[oracle@leodbs]$ mkdir -p /u01/app/oracle/admin/orcl/adump

[oracle@leobin]$ sqlplus / as sysdba
