ggsci: error while loading shared libraries: libnnz11.so: cannot open shared object file

完整的错误信息如下:

ggsci: error while loading shared libraries: libnnz11.so: cannot open shared object file: No such file or directory

在通过ggsci启动时，有可能会遇到如上错误。找不到libnnz11.so动态库文 件. 通过find命令发现该文件在"$ORACLE_HOME/lib"路径中存在的:

$ find $ORACLE_HOME/ -name libnnz11.so
/u01/app/oracle/product/11.2.0/dbhome_1/inventory/Scripts/ext/lib/libnnz11.so
/u01/app/oracle/product/11.2.0/dbhome_1/inventory/backup/2019-03-08_10-41-36PM/Scripts/ext/lib/libnnz11.so
/u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so

难道是LD_LIBRARYPATH 没有配置该路径么？

查看LD_LIBRARYPATH 配置:

$ echo $LD_LIBRARY_PATH
/u01/app/oracle/product/11.2.0/dbhome_1/lib:/opt/jdk1.8.0_181//jre/lib/amd64/server/:/opt/jdk1.8.0_181//lib:

配置是对的。那问题出在哪儿呢？

追踪进程吧:

从追踪结果来看，ggsci 设定的查询路径是"/u01/app/ogg"(这是我的 OGG_HOME路径 ),及该路径下的tls, "/lib64","/usr/lib64" 三个主路径, 并没有根据$LD_LIBRARY_PATH配置的路径去查找，那么我们只有一个办法:

将该库文件复制一份到 以上三个路径中的一个即可。

• 解决方法

  cp $ORACLE_HOME/lib/libnnz11.so $OGG_HOME/
