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

完整的錯誤信息如下:

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

在通過ggsci啟動時，有可能會遇到如上錯誤。找不到libnnz11.so動態庫文 件. 通過find命令發現該文件在"$ORACLE_HOME/lib"路徑中存在的:

$ 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

難道是LD_LIBRARYPATH 沒有配置該路徑么？

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:

配置是對的。那問題出在哪兒呢？

追蹤進程吧:

從追蹤結果來看，ggsci 設定的查詢路徑是"/u01/app/ogg"(這是我的 OGG_HOME路徑 ),及該路徑下的tls, "/lib64","/usr/lib64" 三個主路徑, 並沒有根據$LD_LIBRARY_PATH配置的路徑去查找，那么我們只有一個辦法:

將該庫文件復制一份到 以上三個路徑中的一個即可。
