数据库库报ORA-09925: Unable to create audit trail file,当时查 df -h有可用空间,目录的权限也正确,未df -i查看Inodes使用情况,审计目录下有将近24W个文件,初步猜测是因为审计生成文件过多导致目录所在分区的Inodes用光了,当时删除部分审计TRACE文件后正常未查看 Inodes使用情况。
汇总了下:ORA-09925的原因大致有以下三种:--其实可以根据报错判断是权限问题还是磁盘空间问题
原因一:目录权限问题--目录权限被改,无权限向目录写审计数据
Oracle bin目录(实际是整个oracle目录)的属主被更改: --ls -al bin
解决方法
chown -R oracle.oinstall /opt/orace
原因二:确实磁盘没空间了 --df -h
原因三:磁盘Inodes用光--df -i
参考:模拟Linux磁盘分区有可用空间无可用Inodes时报错:No space left on device
报错示例:--部分网络
示例1:可以根据报错信息判断是目录权限问题导致不能写入
ORA-09925: Unable to create audit trail file
Linux Error: 13: Permission denied
Additional information: 9925
ORA-09925: Unable to create audit trail file
Linux Error: 13: Permission denied
Additional information: 9925
示例2:--只读文件系统--没有写权限(可能是文件系统出问题)
ORA-09925: Unable to create audit trail file
Linux-x86_64 Error: 30: Read-only file system
Additional information: 9925
ORA-01075: you are currently logged on
示例3:--没有可用空间

MOS上的一段描述及解决:
Problem Description -------------------
Problem occurs when: $ORACLE_HOME/rdbms/audit directory is full or $ORACLE_HOME/rdbms/audit directory doesn't exist as a side effect of this problem oracle asks for password after connect internal
Solution Description --------------------
Make space available in $ORACLE_HOME/rdbms/audit by removing files that are not needed or Make sure the directory exists and is readable by oracle or Change init.ora audit_file_dest to an existing directory. Change init.ora parameter means restart instance as workaround kill pmon.
Explanation -----------
The behavior on Unix is to write a file named ora_
ORA-09925: "Unable to create audit trail file"
Cause: ORACLE was not able to create the file being used to hold audit trail records.
Action: Check the UNIX error number for a possible operating system error.
If there is no error, contact ORACLE customer support.
