计划做一次备份还原测试，在另外一台服务器上安装好了SAP和nbu client，拷贝backint和配置文件到适当目录，并按实际情况做修改，但是在nbu 服务器端验证客户端时提示：cannot connect on socket，检查了网络和hosts文件都没有问题，最后一气之下重新安装，又自己好了，搞不懂！
完事后使用brbackup测试备份的时候一直提示输入oracle的密码都不对，按网上的方法：
conn / AS SYSDBA 登陆
alter user sys identified by 新密码
alter user system identified by 新密码
------------------------------------------------------
修改完oracle的密码，然后尝试登录sqlplus
sqlplus /nolog
conn /as sysdba
结果提示： “connected to an idle instance";
继续输入startup准备启动实例，又提示： "insufficient privileges"
只能关闭退出。
———————————————————
使用sqlplus "/as sysdba"
startup
可以成功启动实例，但运行brbackup
结果还是：'CONNECT system/******** AT PROF_CONN IN SYSOPER MODE'
ORA-01031: insufficient privileges
进入sqlplus
SQL> connect system as sysoper
Enter password:
ERROR:
ORA-01031: insufficient privileges
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> grant sysoper to system;
Grant succeeded.
SQL> connect system as sysoper
Enter password:
Connected.
SQL>
搞定实例和权限问题

再次使用 brbackup提示libnbclient.dll，这个是因为安装升级包后没有把backint.exe覆盖，轻松搞定，但是运行还是出现错误：

睁大牛眼仔细检查了配置文件，确实没有发现大问题，在netbackup 服务器上看了一下日志，发现问题在于，自己的磁带没有满但全部使用过，可能Retention不同，找了一盘磁带先过期，然后后专门划分给这个客户端的备份策略，果然不出现上面的错误，但是又出现新的错误：客户端brbackup运行一会就中断了，系统错误日志：
Faulting application backint.exe, version 7.0.2010.707, time stamp 0x4c3572a3, faulting module MSVCR80.dll, version 8.0.50727.6195, time stamp 0x4dcdd833, exception code 0xc000000d, fault offset 0x000000000002a696, process id 0x5d0, application start time 0x01cc52fcca183549.
最后找到的原因居然：log下没有见创建backint文件夹【（primary) The backint process crashes if the backint log directory is not
created or not with full permission】，赛门铁克也太搞笑了，你的系统在安装的时候创建个文件夹有那么难吗？！
创建了文件夹，还真管用，终于可以看见成功备份了。
