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@testdb bin]$ pwd/usr/openv/netbackup/bin[oracle@testdb bin]$ ls oracle_link oracle_link[oracle@testdb bin]$ ./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/app/oracle/product/11.2.0/db_1 Oracle version: 11.2.0.3.0 Platform type: x86_64 Linking LIBOBK:ln -s /usr/openv/netbackup/bin/libobk.so64 /oracle/app/oracle/product/11.2.0/db_1/lib/libobk.so Done再次启动备份，，问题解决
