nbu 备份oracle数据库出错

tim123

我已经搞定了。

打开了nbu得详细日志，根据 bprd_connect: Cannot authenticate server jerry: 18 信息查找发现如下得解释：

Exact Error Message
<16> dbc_GetMediaListByName: Can't connect to host jerry: authentication failed (160)

Details:
The dbclient log will indicate the following error messages:
10:13:58 [8059] <2> bprd_connect: Cannot authenticate server jerry: 18
10:13:58 [8059] <16> dbc_GetMediaListByName: Can't connect to host jerry: authentication failed (160)
10:13:58 [8059] <16> find_backup_image: GetMediaListByName() failed
10:13:58 [8059] <4> error_setup: entering error_setup.
10:13:58 [8059] <16> sbtbackup: Failed to process backup file.
10:13:58 [8059] <4> sbterror: entering: errcode=7501, errtxt=sbtbackup: Failed to process backup file..

This error indicates a permission conflict with the directory "var" under /usr/openv/var.  
If the permission on the var directory file is 500, i.e:
ls -ltr /usr/openv/
drwx------ 3 root other 512 Feb 6 18:10 var

then this is incorrect.
Make sure the permission for this directory is 755, i.e:
drwxr-xr-x 3 root other 512 Feb 6 18:10 var

To change the permissions, perform the following from a command prompt:
chmod 755 /usr/openv/var


修改了目录/usr/openv/var的权限，备份即正常了。
