數(shù)據(jù)庫：oracle11.2.0.4

系統(tǒng)：anolisos7.9

環(huán)境：系統(tǒng)中安裝過11g數(shù)據(jù)庫實(shí)例，同時(shí)也安裝了19.3數(shù)據(jù)庫軟件.

問題描述：

在
/u01/app/oracle/product/19.3.0/db_1目錄下使用deinstall命令后，11g數(shù)據(jù)庫狀態(tài)顯示正常，但連接報(bào)錯(cuò)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

ERROR:

ORA-09925:Unable to create audit trail file

Linux-x86_64Error: 2: No such file or directory

Additionalinformation: 9925

異常原因：

無法創(chuàng)建審計(jì)文件，若以sysdba用戶登陸數(shù)據(jù)庫都會(huì)被強(qiáng)制審計(jì)，如果審計(jì)文件無法寫入，肯定會(huì)有問題.

解決過程：

使用strings查看二進(jìn)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

發(fā)現(xiàn)該目錄不存在，判斷為deinstall19c時(shí)該目錄被刪除.

新建該目錄后，連接無異常.

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

[oracle@leobin]$ sqlplus / as sysdba
