我试图使用Oracle.jl从julia连接到Oracle XE 11g2，如下所示。
环境：CentOS 7.5 64bit CentOS 7.5 64bit
a) 已下载 instantclient-basic-linux.x64-19.6.0.0.0dbru.zip 并解压到stdlib文件夹 /opt/julia/julia-1.4.1/share/julia/stdlib/v1.4
b) julia配置 etcprofile.djulia.sh内容。
#!/bin/sh
export JULIA_HOME=/opt/julia/julia-1.4.1
export JULIA_LOAD_PATH=/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4
export JULIA_DEPOT_PATH=/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4
export JULIA_PKG_DEVDIR=/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4
export JULIA_PROJECT=/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4
export JULIA_HISTORY=/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4/logs/repl_history.jl
export PATH=$JULIA_HOME/bin:$PATH
c) julia脚本，oraConnTest.jl内容。
import Oracle
global const dbHost = "localhost";
global const dbClientType = "thin";
global const dbName = "xe";
global const dbPort = "1521";
global const schema = "test";
global const dbUserPassword = "test2357";
global const conn_str="//"*dbHost*":"*dbPort*"/"*dbName;
conn = Oracle.Connection(dbUserName, dbUserPassword, conn_str);
rs=Oracle.query(conn, "SELECT * FROM TAB");
println(rs[:,1])
conn.close();
我得到以下错误。
julia> include("/root/oraConnTest.jl")
ERROR: LoadError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "libclntsh.so: cannot open shared object file: No such file or directory".
更新1。
但是，我的JULIA_LOAD_PATH里有libclntsh.so，如下所示。
[root@srvr0 ~]# find / -name libclntsh.so
/index/instantclient_19_6/libclntsh.so
/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4/instantclient_19_6/libclntsh.so

我尝试了find命令中列出的libclntsh.so的所有三个路径。但问题仍然存在。
请帮助我解决上述问题。
设置 PATH 你的甲骨文 .so 文件。Oracle驱动程序通常需要在 PATH.
export PATH=$PATH:/opt/julia/julia-1.4.1/share/julia/stdlib/v1.4/inst
