检查带库、和脚本都没有问题，网络解析也没问题

解决方法：

symantec nbu在备份是需要调用oracle lib库文件，symantec bin目录下提供了此脚本

[oracle@orc1 bin]$ pwd

/usr/openv/netbackup/bin

[oracle@orc1 bin]$ ls oracle_link

oracle_link

[oracle@orc1bin]$ ./oracle_link

All Oracle instances should be shutdown before running this script.

Please log into the Unix system as the Oracle owner for running this script

Do you want to continue? (y/n) [n] y

LIBOBK path: /usr/openv/netbackup/bin

ORACLE_HOME: /oracle/db/oracle/app/oracle/product/11.2.0/dbhome_1

Oracle version: 11.2.0.3.0

Platform type: x86_64

Linking LIBOBK:

ln -s /usr/openv/netbackup/bin/libobk.so64/oracle/db/oracle/app/oracle/product/11.2.0/dbhome_1/lib/libobk.so

Done

Please check the trace file located in /tmp/make_trace.12823

to make sure the linking process was successful.

再次启动备份，问题解决。
