asm添加数据文件时出现ORA-01157错误，文件大小为SIZE -8192！

背向天堂

数据库版本：10.2.0.4.0
操作系统版本：HP-UX B.11.23
单机

前段时间安全检查，修改了sqlnet.ora文件，增加了sysdba不能空口令登录的配置：
sqlnet.REMOTE_LOGIN_PASSWORDFILE=NONE
sqlnet.authentication_services=NONE

今天在添加数据文件的时候出现权限不足的错误，按以往的经验，屏蔽sqlnet.ora里面的配置就能正常操作。

但将sqlnet.ora临时重命名后，执行添加操作仍然报错，错误日志如下：

通过dbms_metadata包检查该表空间的ddl属性，发现几次失败操作后的数据文件都是 -8192

CAUSE

Improper Primary Group for the db_home owner

From all nodes:
* 'id' output for the <db_home> owner is: uid=60011(oracle) gid=60011(dba) groups=501(oinstall),60011(dba)
* The owner:group and file permissions for asm_home and db_home, is oracle:dba and 6751:
  -rwsr-s--x 1 oracle dba 196655349 Jan 21 16:13 /usr/app/oracle/product/asm/bin/oracle
  -rwsr-s--x 1 oracle dba 196658908 Jan 21 16:02 /usr/app/oracle/product/11.1.0/bin/oracle
* The ASM disks are owned by oracle:oinstall and all have 660 permissions
* The <db_home>/rdbms/lib/config.c shows proper values for SS_DBA_GRP (dba) and SS_ASM_GRP (oinstall):
  #define SS_DBA_GRP "dba"
  #define SS_OPER_GRP "oinstall"
  #define SS_ASM_GRP "oinstall"
* There is no sqlnet.ora file from any of the <asm_home>|<db_home>/network/admin directories (here we are looking if the parameter SQLNET.AUTHENTICATION_SERVICES is set to NONE)

SOLUTION

Change the Primary Group for the <db_home> owner from 'dba' to 'oinstall':

For example:

# id oracle
uid=60011(oracle) gid=60011(dba) groups=501(oinstall),60011(dba)

# /usr/sbin/usermod -u 60011 -g 501 -G 60011 oracle

# id oracle
uid=60011(oracle) gid=501(oinstall) groups=501(oinstall),60011(dba)

需要的信息

id oracle
ls  -l $ORACLE_HOME/bin/oracle
ls -l $CRS_HOME/bin/oracle

背向天堂

感谢刘大，这套库是单节点的。


$ id oracle
uid=200(oracle) gid=200(oinstall)

$ ls  -l $ORACLE_HOME/bin/oracle
-rwsr-s--x   1 oracle     oinstall   284460824 Nov  1  2008 /oracle/app/oracle/product/10.2.0/db_2/bin/oracle

oracle只有一个组，很少维护，去年出过一次类似的问题，屏蔽sqlnet.ora里面的设置就可以了。

但是这次修改以后，仍然有问题。而且库是非归档的，目前不敢重启，准备让应用的人备份以后在做重启操作。

为什么是非归档呢 存储不够？
